[In the core area, a large amount of rich spiritual energy rushed towards us, and countless spiritual medicines were in the spiritual fields. ]

[But these spiritual medicines are not yet capable of being refined with your current alchemy level.]

[So you directly passed those spiritual fields and took out all the spiritual stones in the spiritual gathering array.]

[You did not disturb the Master Wanmu in the bronze sarcophagus. Before leaving, you took a reluctant look at the spirit dragon.]

[After leaving the ancient tomb, you took out Zong Laogou's diary and found the location of the Five Elements Mountain.]

[In front of the Five Elements Mountain Ruins Formation, you felt a slight pain between your eyebrows. ]

[This means that if you step into the Five Elements Mountain ruins, your life will be in danger.]

[For the sake of caution, you decide to put aside the exploration of the Five Elements Mountain ruins for the time being and continue to collect more Spring Dew Pure Water.]

[In the 20th year, you return to the real world and continue to collect spring dew water.]

【This year, the amount of your spring dew water has reached 190 drops. 】

[From now on, you will collect spring dew and clean water every year on the day of Jingzhe, and practice diligently.]

[Four years have passed in the blink of an eye. ]

[In the twenty-fourth year, after the Waking of Insects Day, you already have 230 drops of spring dew and pure water.]

[Although you have strengthened your practice of the Fire Separation Technique, you find that you are still a long way from mastering the Fire Separation Technique.]

[The biggest problem is that your current spiritual power is not enough to make the Fire Breaking Technique explode with extremely high temperatures.]

[Perhaps after reaching the Return to Void Stage, when my cultivation base increases dramatically, I will be able to better activate the Fire Separation Technique.]

[In the twenty-fifth year, hundreds of legendary monsters broke through the Monster Suppression Pass, and a large number of human warriors died in the battle.]

[A small number of powerful human beings escaped back to the real world, preparing for a final resistance. ]

[And you, after collecting this year's spring dew and pure water, are ready to explore the Immortal Martial Era dungeon again.]

[You came to the Five Elements Mountain, broke the ruins formation, and walked into the ruins tomb. ]

[According to the information you have obtained, the person sleeping in this ancient tomb should be a powerful cultivator from the Five Elements Sect, a powerful immortal cultivation sect thousands of years ago.]

When Su Xing saw this, he felt a little excited.

"Inside the ruins of the Wanmu Sect, the one sleeping is Wanmu Zhenren..."

"Could there be a powerful being in the Fusion Stage sleeping in the Five Elements Sect's ruins?"

Thinking of this, Su Xing felt a little nervous and expectant.

After all, there are many good things in the Wanmu Sect ruins, such as spiritual medicine, spiritual stones... and even a fully formed spiritual dragon! If there are also these in the Five Elements Sect ruins, then Su Xing will make a fortune!

"Tsk tsk, when I reach the fusion stage, I will definitely lift the coffin lids of all you old antiques!"

Su Xing initially had a good impression of these powerful monks, but after knowing what Master Wanmu had done, Su Xing immediately lost all his good impression of them.

Thinking of this, Su Xing looked at the simulation panel.

[The Five Elements Sect's formation is stronger than you thought, but you still broke it and entered the ancient tomb ruins.]

[After passing through the long and narrow tomb passage, the road ahead gradually becomes wider. You suddenly become alert, activating your Yuanli armor and supporting your body's protective Qi.]

[After walking a few miles forward, a dark shadow suddenly flashes before your eyes.]

[An astonishing force hits your protective Qi, and it is instantly shattered.]

[Even with the protective qi cushioning you, you were still knocked down by a punch onto the stone wall of the ancient tomb, and your entire chest was in pain.]

[You were shocked instantly, and at the same time you saw clearly the appearance of the person in front of you.]

【This is a living dead! 】

[However, this living dead is much more powerful than the living dead puppet in the Wanmu Ruins. ]

[When this living dead was alive, he was at least in the late stage of the Void Breaking Realm, or even close to the Great Perfection of the Void Breaking Realm! ]

[You carefully looked at this living dead and found that his hair and beard were all white, even his eyebrows were white, very much like the Taoist priest with white eyebrows in a certain movie.]

[But his condition was extremely miserable at this time, his pale hair was a mess, his face was pale, and he was filled with endless resentment! ]

[Seeing the living dead coming at you again, you immediately raised your protective Qi without a second thought and ran towards the core area of ​​the ruins.]

[Fortunately, your flight speed has increased a lot, and this living dead man seems to have a disabled leg, so he couldn't catch up with you immediately. ]

[You ran forward at full speed, and in a few breaths you arrived at the core area of ​​the Five Elements Mountain Ruins and Tomb.]

[Strangely, there seems to be no formation in the core area of ​​this ancient tomb...]

[No, it seems that there was a formation before, but it was violently destroyed by someone! ]

[While you were running for your life, you were filled with doubts. Could it be that Zong Laogou had been here before? ]

[But you quickly denied it, because the diary of the old dog of the sect described in detail that he did not dare to set foot on the ruins of the Five Elements Sect.]

[Soon, as you entered the core area, you noticed a huge bronze sarcophagus.]

[It looks very similar to the one in the Wanmu Ruins, but the difference is that the painting on this bronze sarcophagus is not a large forest, but the five elements of gold, wood, water, fire and earth...]

[What makes you even more confused is that this bronze sarcophagus has been opened, and the monk who was supposed to be sleeping inside has disappeared.]

[You suddenly have a thought in your mind: the living dead chasing you is the monk who was supposed to be sleeping in the sarcophagus! ]

[But for some unknown reason, this monk who was supposed to be sleeping revived early and turned into this living dead appearance. ]

[But at this moment, the living dead are still chasing you, and you can't think about the reason carefully. ]

[You begin to look for useful treasures in this ruins. ]

[Your spiritual sense quickly scanned every corner of the core area, but did not find a large area of ​​medicinal fields, nor did you find other living dead puppets.]

[I only saw a few skeletons that looked like jade.]

[What makes you a little disappointed is that there is no trace of the spirit dragon in this ruins. ]

[But you found a lot of spiritual stones in a corner. ]

[At this moment, the living dead behind him are chasing him again. ]

[You grit your teeth and once again raise your protective Qi, running straight towards the spirit stone.]

[You quickly put the spirit stone into the storage device, and at this moment, the living dead behind you have attacked again.]

[This time his attack is even more fierce! ]

[Fortunately, you were protected by the protective qi, so you didn't die immediately, but you were seriously injured and looked extremely miserable.]

[You have a sudden thought and prepare to flee to the Lingtian Cave to temporarily avoid the attacks of the zombie puppets.]

[However, there seems to be a space formation in this ancient tomb, which slows down your entry into the Lingtian Cave Heaven by one second.]

【And this second is fatal! 】

[Your body was badly damaged by the repeated attacks of the living dead.]

[You are forced to leave your body in the hope of escaping.]

[But the living dead will not give you any chance and will directly destroy your soul. ]

【You are dead! 】

[Ding, this simulation ends! ]

After the simulation ended, Su Xing frowned, as if he was thinking.

"Why are the Five Elements Sect ruins different from the Ten Thousand Trees Sect ruins... Why are there no spirit vein dragons in them?"

"Why... the Master of the Wanmu Sect is still asleep, but the cultivator of the Five Elements Sect who has reached the Great Perfection of the Void Breaking Realm has revived ahead of time?"

Su Xing seemed to have captured several key pieces of information in his mind, but he couldn't connect them together for a while.

"Wait... Master Wanmu, cut off the spiritual veins of the world, gather spiritual dragons, and cultivate himself..."

"Maybe, people from other sects don't know about this at all!"

"It is precisely because the spiritual vein was cut off that the spiritual energy quickly dried up over the past few hundred years..."

"As for the Five Elements Sect cultivator who turned into a living dead...I'm afraid it's also related to Master Wanmu!"

Su Xing seemed to have captured the key information.

"In this way, the resentment rising from the living dead can be explained..."

"Perhaps someone discovered Master Wanmu's plan, which is why a fight broke out in the Wanmu Sect ruins and why there are zombie puppets in the Wanmu Sect ruins?"

Su Xing was thoughtful and felt that if he continued along this line of thought, he should be able to find the answer.

"However, how to try it specifically... I still need to go to the Immortal Martial Era instance to look up ancient historical books and search for it..."

Su Xing sighed. Thousands of years have passed, and those historical books should be hard to find.

However, there may be some traces in the three major sects of the Xianwu era copy.

Su Xing plans to explore it when he has time later. Perhaps this information will be helpful to Su Xing in exploring the ruins and ancient tombs.

"But, in short, the purpose of this simulation has been achieved!"

"Spring dew, pure water, spiritual stones... With these, I believe my cultivation in the Return to Void Stage will be smoother!"

Thinking of this, Su Xing turned his gaze to the reward for this simulation.

[I am not the Rain God]: Purple talent, priced at 1 million energy points.

[Twenty Years of Alchemy Experience]: Enlightenment of alchemy, including the Rebirth Pill (mid-grade perfect, top-grade entry-level), price of enlightenment, 7 million energy.

[Two Hundred and Forty Drops of Pure Spring Dew Water]: The first ray of rootless water that falls on the day of Jingzhe, contains mysterious power and can be used to refine Lianxu Pills. There are 240 drops in total and the selling price is 24 million energy.

[Zong Laogou's Diary]: Sold for 10,000 energy points.

[1,000 cubic meters of ore containing third- and fourth-order exotic metals]: Worth 15 billion energy, but its value is halved because it contains a large amount of impurities.

Su Xing looked at the simulated rewards without much hesitation.

After all, the purpose of this simulation was to obtain the spring dew pure water and spirit stone resources to prepare for the breakthrough in the Return to Void Period.

But the problem is that Su Xing's simulation energy is not enough! His current simulation energy is only 147.56 million points at most, and it takes 324 million energy to bring out the spirit stone and spring dew water.

Su Xing looked at the last reward option with a look of surprise on his face.

"The third and fourth level exotic metals contained in the Red Lotus Demon Cave are actually worth 15 billion energy?"

"Wait... after the simulator charges a tenfold price difference... it should be 1.5 billion simulation energies!"

Seeing such a huge amount of energy, Su Xing's heart almost jumped out.

1.5 billion energies are enough for him to cultivate to the state of Breaking the Void Realm and reaching the state of Returning to the Void Realm!

"But...how come the value is halved?"

Su Xing asked with some doubt.

And the simulator also gave Su Xing a rare answer.

[Ding, since the proportion of foreign metals contained in this ore is 3.7%, it is a secondary energy material... If it is purified, it can be worth 3 billion energy. ]

Su Xing immediately understood what the simulator meant.

"So, if I absorb it directly, it's worth 1.5 billion energy... and after purification, it's worth 3 billion energy?"

Su Xing was a little excited. Whether it was 1.5 billion or 3 billion, it was a huge sum of money for Su Xing! "In that case, we should go to the Red Lotus Demon Cave dungeon first!"

Su Xing murmured.

He had previously used the immersive simulation function to completely simulate the scene of heading to the Red Lotus Demon Cave.

Now if I go there again in the real world, it will definitely be safe! Thinking of this, Su Xing took a look at the sky and began to disguise himself.

When it got a little dark, Su Xing left Kyoto Academy and ran out of Kyoto city.

After making sure that no one was paying attention to him, Su Xing used the Heavenly Secret Shielding Technique, then flew on his sword and rushed to Mayi City in the Northwestern Province.

Soon, Su Xing arrived near the Red Lotus Demon Cave copy in his memory.

When Su Xing got closer, he indeed found a fully armed army of professionals hanging around outside the Red Lotus Demon Cave dungeon.

As a forbidden-level copy, the Red Lotus Demon Cave must naturally be strictly controlled.

These professional armies are not only to prevent monsters from escaping from the dungeon, but also to prevent people from accidentally entering it.

However, the strength of these professional soldiers is only around the master or grandmaster level, and they dare not get too close to the entrance of the copy.

Su Xing simply used the Eight Trigrams fortune-telling technique to block these people's perception of himself, and successfully blended into the Red Lotus Demon Cave copy.

To Su Xing today, these master-level professionals are no different from ordinary people.

Stepping into the Red Lotus Demon Cave dungeon, Su Xing quickly entered an unfamiliar environment.

Obviously, this is no longer the Blue Star.

"Hmm... the temperature around me has risen a lot, and the temperature I feel is around 50 to 60 degrees..."

Su Xing nodded slightly, but this temperature was no different from normal temperature to him.

Even though Su Xing's strength is now comparable to that of a legendary warrior, for the sake of caution, Su Xing still raised his body's protective qi and activated his energy armor.

After a little exploration, Su Xing found a cave that went almost straight down and was bottomless, and could only accommodate one person.

"This should be the passage leading to the core area of ​​the dungeon..."

Su Xing didn't hesitate and flew straight into the cave.

Because the cave is narrow, it is impossible to reach the maximum speed.

Therefore, it took Su Xing several hours to reach the Fire Demon area thousands of miles deep.

At this time, the surrounding temperature has skyrocketed to three or four thousand degrees Celsius, and only those who are at the King level or above can survive.

With the help of his spiritual sense, Su Xing quickly discovered the fire demon he encountered in the simulation.

There was no dragging of feet.

The energy wrapped around his arm, and then he punched out! In just a moment, the Flame Demon's life force quickly diminished.

Even the Flame Demon at the peak of the Martial Emperor level couldn't survive a single move from Su Xing! "This is the benefit of steady development!"

“I don’t care what level of enemy you are… Once I’ve grown enough, I’ll kill you all!”

Su Xing raised the corners of his mouth slightly and continued to explore the Flame Demon's lair.

Soon, Su Xing discovered a deeper cave leading to the magma layer.

"Down here, that should be where the exotic metal mining area is..."

Su Xing explored deeper into the cave and soon saw a lava pool.

At this time, the temperature here has reached over 5,000 degrees Celsius.

Fortunately, Su Xing possessed protective Qi that isolated him from the inside and outside, so his body was not affected.

Su Xing looked past the magma pool and towards the ore area on the side.

Sure enough, among the uneven rocks, there were a lot of special red metals mixed in.

"Sure enough, a different metal ore!"

"Then... let's start working!"

Su Xing took a deep breath and took out his spiritual sword Mo Bing.

With the nourishment of Yuanli, the Mo Bing Sword became sharper and tougher.

Su Xing's mind moved, and he wrapped his energy around the Mo Bing sword.

Then he chopped at the rock layer mixed with foreign metals.

Under the action of Yuanli, these uneven rocks were cut into smooth pieces like tofu.

Su Xing cut each piece of ore into one cubic meter size with some obsessive-compulsive disorder.

Then, Su Xing continued mining throughout the night.

It was not until noon the next day that the last piece of exotic metal ore was dug away by Su Xing.

Su Xing was satisfied and ready to leave.

"I got my hands on a thousand cubic meters of ore containing exotic metals... This ore is worth at least 1.5 billion energy!"

"As for whether to purify or absorb directly, we will consider it later... We should not stay here for long, let's leave first!"

Therefore, Su Xing spent several more hours to leave the Red Lotus Demon Cave copy.

He flew on the sword until the evening, when he returned to the dormitory.

Su Xing decisively entered the blessed land of Lingtian, and felt relieved, but he couldn't help but feel his heart pounding.

"Wow, this is a metal worth 1.5 billion energies!"

Su Xing looked at the mountain of strange metals in front of him and began to think.

"If it is absorbed directly, it is only worth 1.5 billion energy..."

"But if it is purified, it will be worth 3 billion energy!"

"However, I guess it will take a lot of time to purify this exotic metal... I just don't know how long it will take?"

Su Xing hesitated for a moment, then called Jin Congxue.

"Hello, busy man, how come you have time to call me?" Jin Congxue's voice came from the other end of the phone.

Su Xing chuckled and said, "Ahem... I have something to ask you. Those exotic metals need to be purified and refined, right?"

Jin Congxue gave a positive reply from the other end of the phone:

"You are talking nonsense, aren't you? You are the boss who has contracted six mining dungeons! You don't even know this?"

"Mining is not easy, but purification also takes time. The exotic metals you obtain every week probably need to be purified four to seven days in advance..."

"Of course, the higher the grade of the exotic metal, the more time it will take to purify and refine it."

Su Xing showed a look of astonishment when he heard this, so he asked: "Sister Xue, if it is a thousand cubic meters of ore containing third or fourth-level exotic metals and a purity of about 3.7%... how long will it take to purify and refine it?"

Jin Congxue didn't expect Su Xing to ask such a detailed question in such a serious manner.

After thinking for a moment, he said, "According to your description... I estimate that it will take about a month to purify this batch of ore..."

Su Xing's eyes lit up after hearing this. In one month, he purified 1.5 billion worth of exotic metals, which means he made 3 billion directly! Hiss~ This is a lot of money! "But there is a problem... If I purify all of it, then I will have no simulation energy to use next..."

After hesitating for a while, Su Xing decided to absorb one third of the alien metal first, which was 500 million simulation energies.

The rest was given to Jin Congxue for purification.

"There are more than 600 cubic meters left. It should take three weeks to purify it... By then, 1 billion energies will become 2 billion!"
