"Yes, it is the magic armor. In fact, the magic armor was created by Changshengtian, and it is just an accessory for the experiment." Sha Chu's words became more and more unbelievable.

Li Xiu didn't know what to say and could only wait for Sha Chu to continue.

"What do you think the evil spirit is?" Sha Chu seemed to be keeping people on suspense. He did not continue talking and instead asked Li Xiu a question.

"I don't know. Maybe it's a creature from a planet with a different civilization in the universe, or maybe it's a creature from another space." Li Xiu shook his head.

"If I say that evil spirits have existed on Earth for a long time, would you believe it?" Sha Chu continued to ask.

"This is hard to believe." Li Xiu thought of the Jedi Spike. Could a demon like that be considered the one that has existed on Earth for a long time?

"Well, let me ask you, what do you think the value of the gem itself is?" Sha Chu did not answer Li Xiu's question, but instead asked another question.

"Of course the value of gems is very high." Li Xiu said.

"What if it was before the appearance of the demon spirits and the Gate of Trials? Do you think the gem's usefulness is worth its price?"

"Maybe it's not worthy." Li Xiu thought about it carefully. If there were no magic spirits and the trial gate, most gems would be just decorations. Compared with their prices, their own functions are not that high.

"Have you ever wondered why gemstones that can only be used as decorations are so expensive?"

"Because he's rare?"

"Some gems are indeed rare, but most are not as rare as you think. For example, diamonds have an astonishing reserve. If used in industry, artificial diamonds can completely replace natural diamonds. However, before the advent of the demon spirit, the price of diamonds continued to rise. Have you ever thought about why?"

"Why?" Li Xiu always thought that it was a means of capital, but listening to Sha Chu's tone, it seemed that it was not the case.

"Thousands of years ago, a man got a gem. Due to an accident, he discovered that there was a strange creature in the gem..."

Sha Chu told a story. Although she told it vaguely, it could be heard that this should be the origin of the Changshengtian organization.

Thousands of years ago, a man obtained a magic spirit from a gem, and with the help of the power of the magic spirit, he became immortal and has lived until now.

He has been studying the relationship between gems and evil spirits. In order to obtain more gems, he founded the Changshengtian organization.

With the progress of the times, the means of mining gems have become more and more advanced, more and more gems have been obtained, and the research results of Changshengtian have also increased.

But they still didn't understand the relationship between gems and evil spirits. The vast majority of gems were unable to give birth to evil spirits, and only a very small number of gems contained evil spirits.

There are almost no inevitable rules here. One thing in common is that the gems that generally have magic spirits are top-grade gems that are large enough and pure enough.

But this is not absolute. Occasionally, some smaller gems may contain evil spirits.

Moreover, even for top-level gems, the chance of a magical spirit appearing is very low. Until now, they still have no way to distinguish which gems have magical spirits and which gems do not.

During thousands of years of research, they have achieved many results.

Until one day, a gem mine deep underground was discovered and mined, and an unimaginable gem was found there.

When the gem was touched, mankind officially entered the Demonic Age.

Li Xiu knew everything that happened next. Countless demons descended to Earth, and mysterious trial gates appeared all over the world.

Almost everyone who came into contact with the gem died, and there were only a few survivors. The gem mine was also sealed by a huge trial door, and no one could enter there anymore.

Changshengtian was the first organization to come into contact with and study evil spirits, and the magic equipment was also developed by them.

Ximen Guan was originally a member of Changshengtian, but for his own benefit, he stole the information of magic suit and became the "Father of Magic Suit" recognized by the world.

"In Changshengtian, you can get the best of everything, whether it's magic equipment or magic spirits. When it comes to the research on the Gate of Trial, no one is more professional than Changshengtian. People like you should join Changshengtian. Only there can your talents be fully displayed, not to mention you can get the secret of immortality." Sha Chu said.

"After all, these are just stories." Li Xiu murmured.

"Then let's not tell the story. Look what this is?" Sha Chu took out a small box, opened the lid and presented it in front of Li Xiu.

Inside the box was a gem, a sapphire, a rich blue with a velvety texture, and the glow within was like a blooming daisy.

Even Li Xiu, who doesn't pay much attention to gems, can recognize that this is the top-grade sapphire Kashmir Cornflower. Kashmir is the origin and Cornflower is the name given to the color of this top-grade gem by later generations.

The mines in Kashmir had long been almost exhausted, and even before the advent of the evil spirit, Kashmir cornflowers were difficult to find on the market.

Those sapphires that were later described as cornflower-colored were not true Kashmir cornflowers.

"There is a demon spirit inside this Kashmir cornflower. If you are willing to become a member of Changshengtian, it will be yours. You can verify the authenticity of those words yourself." Shachu's voice was as strong as the voice of the devil.

"Didn't you say that Changshengtian hasn't found a way to identify the magic gem? How can you be sure that there is a magic spirit in this gem?" Li Xiu found the loophole in Sha Chu's words.

"There is indeed no way to identify which gemstone owns the magic spirit before the magic spirit chooses its master, but as long as the master of the magic spirit dies, the gemstone left behind naturally does not need to be identified again." Sha Chu said lightly.

"So that's how it is." Li Xiu was secretly shocked. Since magic spirits can be plundered, it would probably be another trouble if Sha Chu found the Jedi magic spirit ring on his finger.

"How about it, are you willing to join Changshengtian?" Sha Chu asked again.

"I've heard so many secrets, can I still say no?" Li Xiu asked back.

"Okay, but you can only take the secret to the underworld." Sha Chu said with a smile.

"Since there is no choice, why are you asking me? How can I summon the evil spirit in the gem?" Li Xiu asked as he took the gem box.

"This is not your pet. How can you summon it and dismiss it at will? You need some time and patience." Sha Chu took out a diary and handed it to Li Xiu, then walked towards the door: "The diary contains the method of summoning the magic spirit. There is food and water in the cabinet next to it. I will come to pick you up in a month. I believe you should be able to summon the magic spirit by then."

As he spoke, Sha Chu had already walked out of the stone room, and the door of the stone room slowly closed.

Li Xiu glanced at the door of the stone chamber and did not look for a way to escape. Instead, he sat down on the stone bench next to him and read the contents of the diary under the light.

In fact, Li Xiu had already known that there must be an evil spirit inside this Kashmir cornflower.

Because when he saw the gem, that feeling of hunger came back again.

Now he just wanted to see what method Changshengtian used to summon the evil spirit in the gem, and whether he would swallow the gem into his stomach like he did.

After reading the diary, Li Xiu realized that he had overthought and it was not the method he had imagined at all.

Changshengtian's method is much dumber and slower than Li Xiu's.

He needs to keep the gem close to him all the time and drip some of his own blood on it every day.

The gem will not absorb his blood, but this process is indispensable. It needs to be repeated over and over again for about thirty days to a year. If there is a demon spirit inside the gem, it can establish a connection with the demon spirit and summon it.

Unlike Li Xiu who directly swallowed the gem and turned it into a ring, the gem will still maintain its original appearance. If you want to wear it, you need to specially make a gold or silver ring setting or pendant setting for it.

The reason why gold or silver is used is that after Changshengtian's research, the magic gem will not be affected by gold or silver. Other metals and the like will affect the connection between the magic spirit and the master.

Just like the gem that Shachu used to summon the two-headed demon, it was inlaid on a platinum ring.

"I might as well just swallow it directly." Only then did Li Xiu understand how difficult it was for Changshengtian to identify whether there was a demon spirit in a gem. Even with this method, Changshengtian had studied it for who knows how many years before discovering it.

Li Xiu put away the gem, walked to the iron cage, and shouted a few more words to the wild-looking Ximen Guan: "Are you really Ximen Guan? Are you interested in chatting? Can you give me some response?"

As a result, Ximen Guan ignored him and just ate his food. When he was full, he lay down on the ground and fell asleep.

After waking up, he drank water from a running water trough in the iron cage. Later, Li Xiu saw an even more disgusting scene.

That guy not only drank water from the sink, but also urinated and defecated in it. Although the sink was filled with running water and looked like it was drained underground river water, it still almost made Li Xiu vomit.

"What a lunatic." Li Xiu shook his head helplessly.

After staying here for two or three days, Li Xiu estimated that Sha Chu should be gone and began to study how to leave this stone chamber.

Li Xiu knocked in the stone chamber for a long time and found that the inside was in the middle of the mountain. Except for the main door he came in through, the rest of the room was made of rocks of unknown thickness that could not be opened by human power.

"A magic armor master without magic armor is really helpless in a place like this. Unfortunately, I am no longer a simple magic armor master." Li Xiu's mind moved, and the ring turned into a Jedi Knight.

Li Xiu ordered the Jedi Knights to chop the stone gate. The samurai swords in the Jedi Knights' hands shone with fluorescent light. They chopped the stone wall with one blow, instantly creating a long crack in the stone gate.

But Li Xiu soon discovered that there was only a layer of stone a few centimeters thick outside the stone gate, and inside was a grayish-white substance. When the Jedi warrior's sword slashed on it, it only left a series of shallow white marks.

Li Xiu was not giving up and asked the Jedi Knight to chop the stone wall next to the door. As a result, he found that there was also the gray-white substance inside the stone wall.

The Jedi Knight chopped and chopped continuously for a long time, but only left some marks. He didn't know how long it would take to break through the gray-white substance, which was unknown how thick it was.

"What is this thing? Why is it so hard?" Li Xiu frowned as he looked at the grayish-white substance.

"That is magic ash. It's made by grinding the materials from the demon spirits into powder, and then mixing it with other materials such as iron, zinc, chromium, sand ash, etc. to make magic ash similar to cement. The magic ash here is made from the materials from S-level demon spirits. Your E-level little demon spirit will never be able to cut the door open even if it spends a year chopping." A hoarse voice sounded behind Li Xiu.

Li Xiu was slightly startled and turned around to look, only to see the savage-like Ximen Guan sitting there and looking at him coldly.

"Are you not crazy?" Li Xiu asked Ximen Guan.

"Anyone trapped in a place like this for decades will go crazy. I am crazy, but I am not stupid." Ximen Guan said coldly.

"Are you really Ximen Guan?" Li Xiu asked again.

"I am Ximen Guan, but not the Ximen Guan that woman mentioned. I am not a traitor to Changshengtian. The magic armor was developed by me. Changshengtian not only stole my achievements, but also imprisoned me in this place, turning me into a madman who is neither human nor ghost. Sooner or later, I will settle this account with them." Ximen Guan's eyes were cold, but his face showed no joy, anger, sorrow or happiness.

"You can't get out at all, how can you settle accounts with them?" Li Xiu heard Ximen Guan's tone and it seemed that there was a way to get out.

But if he really had a way, it has been decades, why is he still living a life worse than pigs and dogs here?

As if seeing through Li Xiu's thoughts, Ximen Guan said coldly: "You'd better not have those unrealistic fantasies. I just said that casually. If I could really get out, I wouldn't have been a beast here for decades."

"Everything depends on human efforts. As long as we are still alive, there will always be a way." Li Xiu said.

"It seems that you have not yet accepted the beatings of this cruel society. I hope that after a month, you can still maintain your current state of mind." Ximen Guan sneered, obviously disdainful of Li Xiu's childish ideas.

"Where does this waterway lead to?" Li Xiu asked, pointing at the ditch that was used for eating, drinking, defecating and urinating.

"It's an underground river, but you don't have to think too much about it. The bottom is also reinforced with S-level magic ash, leaving only a few waterways as thick as arms. This is the place where I, Ximen Guan, am imprisoned. They designed it according to the highest standards. Even if God comes, he will be trapped here." Ximen Guan continued to attack Li Xiu.

Li Xiu ignored him and took out the cornflower sapphire from his pocket.

"I advise you not to use it." Ximen Guan hadn't had any contact with people for decades. Finally, someone talked to him and he wanted to interrupt in everything.

"Why?" Li Xiu asked puzzledly.

"The people in Changshengtian are as stupid as pigs. They are not good at research, but they are very good at some crooked ways. They have a way to tamper with the magic gem. Once you really use your own blood to establish a connection with the magic spirit, your life and death will be in their hands. You can only live if they want you to live, and you must die if they want you to die. They call this kind of crooked way a blood seal, which is like some kind of curse with blood as the medium. Do you think that woman is really so kind as to give you a magic gem for free? This is just a means to control you." Ximen Guan explained with a sneer.

"So that's how it is. Blood is the key to the blood seal. If I don't use blood to establish a connection with the evil spirit, will the blood seal be ineffective against me?" Li Xiu asked thoughtfully.

"Of course, the blood seal needs blood to be triggered. Without blood, the blood seal cannot be activated." Ximen Guan looked at Li Xiu as if he were an idiot and continued, "But without blood, how can you establish a connection with the demon spirit?"

"Well, this is actually quite simple." Li Xiu pinched the gem and threw it directly into his mouth like taking a pill, then swallowed it.

"You are also an idiot. If it is possible to establish a connection with the evil spirit in that way, the people of Changshengtian would have tested it out long ago. After all, you also have a evil spirit, why are you still so stupid..." Ximen Guan had just finished speaking when he suddenly saw a blue light coming from Li Xiu's fingers. Strands of crystal light came out from under the skin and gradually formed a sapphire ring on his finger.

"What is this?" Ximen Guan widened his eyes, threw himself against the wall of the iron cage, holding the cage tightly with his ten fingers, and looked at the sapphire ring on Li Xiu's finger with disbelief.

Li Xiu ignored him and summoned a new demon spirit with a thought.

There was a flash of blue light, and the sapphire ring turned into a blue figure in front of Li Xiu.

It was actually a heavily armored knight. Both the knight and the giant horse under him were covered in heavy armor. The knight held a blue crystal-like shield in his left hand and a dark blue knight's spear in his right hand.

Countless blue threads of light flickered inside the shield, like a blooming flower.

Chrysanthemum Knight: E-level monster, can summon E-level monster Chrysanthemum Knight.

"Why is there no ability to evolve?" Li Xiu was a little disappointed. In Li Xiu's opinion, if an E-level magic spirit cannot evolve, it is of little use.

"How did you do it? It's impossible to establish a connection with the Magic Gem using this method. Changshengtian has done countless trials like this. Not to mention eating it, even if the Magic Gem was embedded in the bones, it would be impossible to establish a connection with it. This is impossible... This is unscientific..." Ximen Guan seemed to be greatly stimulated and kept repeating it over and over again.

Li Xiu ordered the Chrysanthemum Knights to attack the gate made of magic ash, but the result was similar to that of the Jedi Knights. This level of power only caused limited damage to the gate made of magic ash. Even if they worked together with the Jedi Knights, it would be impossible to break through the gate within a month.

Li Xiu had to think of another way. Since he couldn't break open the door, he could only think of a way when Sha Chu came next time.

The first thing to do is to get rid of the Fire Lotus Sword on your body, otherwise the Fire Lotus Sword will always be around your body and no matter how good your skills are, you won’t be able to use them.

Now Li Xiu regretted not bringing the magic core with him. Although he knew that the disappearance of the magic core would have an impact on his body, his physical fitness would also become stronger because of the disappearance of the magic core.

There is nothing here now, and Li Xiu can only rely on exercise to improve his physical fitness.

"Can I use the magic spirit to draw out the Fire Lotus Sword?" Li Xiu was struggling alone in the stone chamber.

Ximen Guan sometimes spoke coldly and sometimes asked Li Xiu how he established a connection with the Chrysanthemum Knight. He really was talking incoherently like a madman.

Li Xiu ignored him and just kept on doing his own thing. Unfortunately, the Jedi Knight and the Chrysanthemum Knight were unable to pull out the Fire Lotus Sword from his body.

Li Xiu did not give up. As long as he kept practicing, even if he could not pull out the Fire Lotus Sword, he would try it next time Sha Chu came.

There was no tool to calculate time in the stone chamber, so Li Xiu could only calculate time by feeling, and a long time passed in a flash.

On this day, Ximen Guan suddenly became quiet, sitting there blankly, no longer making any noise, and no one knew what he was thinking about.
