Li Xiu turned around and looked at the demon spirit in the crystal. It was still lying there, trapped inside the crystal without even opening its eyelids.

"Human, don't doubt it. It is me who is communicating with you. It is normal that low-level carbon-based creatures like humans cannot understand this advanced way of communication. You don't need to feel inferior." The voice sounded in Li Xiu's mind again.

Li Xiu was a little amused. How could this guy tell that he was inferior? Where did this condescending sense of superiority come from?

"Human, your luck has come. This king just needs a younger brother. If you become this king's younger brother, you will gain supreme glory." The voice continued.

Li Xiu stared at the demon spirit in the crystal in a daze, thinking to himself, "Are people so straightforward when it comes to deceiving people now? There is no technical content at all. What kind of people did this guy come into contact with before? How could he be deceived by a scum like this and become a subordinate? What gave him such confidence?"

"This ball is too straight, it's almost hitting me, you could at least make a turn, even if it's a small turn. Even if you can't perform miraculous powers, at least act noble. What little brother, are you kidding me? Are you insulting my intelligence? Even if you give it a fancy name, like Spokesperson for Gods, Spokesperson for the Devil, etc., it would be understandable if I fell for it. If I fall for it if you do this, wouldn't that make me look stupid?"

Seeing that Li Xiu had been silent, the demon seemed to have misunderstood something and continued, "Human, you don't need to doubt it. You are so lucky to have been favored by this king. But don't be too happy too soon. This is only temporary. Whether you can truly become my younger brother depends on your performance during the probation period."

"Is this evil spirit crazy? It wants to trick me into becoming its subordinate, and there's even a probation period. I've never encountered such a thing in my life." Li Xiu looked at the evil spirit in the crystal and felt that nothing he had encountered in his life was as outrageous as what happened today.

"Which one, what should I call you?" Li Xiu felt that this demon spirit seemed to have some problems with its brain and didn't seem very smart. Maybe he could have a good chat with it.

"Remember, I will only say this once. My title is the Supreme King who is invincible in the entire universe and looks down on the world." Although the evil spirit was lying there motionless, but from its voice, it seemed as if it had already raised its face to the sky.

"Supreme king who is invincible in the universe and looks down on the world, may I ask what level of demon spirit you are?" Li Xiu thought this demon spirit was quite interesting.

"Not bad, not bad. You, my little brother, are not bad. You are not as stupid as those humans in the past who couldn't even remember my title and still wanted to be my little brother. How could I give them a chance? You are very good and can remember my title." The Gai Shi King seemed very satisfied that Li Xiu could remember his title and praised him repeatedly.

“But you don’t need to know about my affairs. You just need to do your best to complete the tasks I give you, and you will naturally receive supreme glory.” said the Great King.

"I wonder what you want me to do?" Li Xiu asked.

"Go and bring me ten Glorious Magic Cores first." King Gai Shi said without even thinking.

"I don't know how long this thing has been trapped underground. It has been thinking about ten glorious magic cores for who knows how many years." Li Xiu pondered and said, "Supreme King of the Eight Desolations and Six Combinations, invincible and invincible, your request is very reasonable, but you see, I am just a weak carbon-based creature, I am afraid I don't have the ability to kill the glorious demon spirit. How can I get ten glorious magic cores?"

"What you said makes sense. Humans are such weak creatures that they really don't have the ability to get the Radiant Magic Cores that I need." King Gai Shi seemed to be in a dilemma. After pondering for a moment, he seemed to have thought of something and said to Li Xiu excitedly, "I remember now. When I came out of the Trial Gate, I saw a ruby ​​mine nearby. You can dig up the ruby ​​mine and go to Black Death City to trade for Radiant Magic Cores. If you mine all the ruby ​​mines, you should be able to exchange for ten Radiant Magic Cores."

"Are you the king of Black Death City?" Li Xiu's heart moved.

If this guy really came from the Black Death City, that means there should be a ruby ​​mine near the City of Light. This is great news.

"Hmph, the king of Black Death City is nothing. I am much stronger than him." King Gai Shi paused and said, "Now I will give you the location of the ruby ​​mine. You must dig out all the rubies in the mine as soon as possible and then take them to Black Death City to exchange for the Radiant Magic Core."

Li Zheng was wondering how King Gai Shi was going to tell him the location of the ruby ​​mine when he suddenly felt a map appear in his mind.

This map is like a 3D image, or a mini sandbox, where you can see mountains, water, and forests.

The mountain in the most central position should be the stone mountain before the City of Light was built. Some distance away from the stone mountain, there is a flashing red dot, which should be the location of the ruby ​​mine marked by King Gai Shi.

Li Xiu roughly judged that the place where the red dot was flashing should be about ten miles northwest of the City of Light.

"I remember that it should be a stone valley over there, but I haven't heard of anyone finding rubies there? When the Lord of Hongsha City opened the mountains and built the city here, he must have investigated the surrounding conditions. How could a ruby ​​mine be undiscovered in such a close distance?" Li Xiu was skeptical.

"As my temporary younger brother, if you can handle this matter well, I can consider promoting you to be my official younger brother." The voice of King Gai Shi sounded in Li Xiu's mind again.

"Don't worry, I'll go there and take a look. I hope the gem mine has not been discovered by others yet." Li Xiu said this but did not move.

"Why don't you go quickly?" King Gai Shi asked in confusion when he saw that Li Xiu did not move.

"I have a question and wonder if you can answer it for me?" Li Xiu said thoughtfully.

"Speak." The Great King was very straightforward.

"If a weak human like me goes to dig in a gem mine, it will definitely take a long time to dig out all the rubies. Why don't you go with me? With your great power, this can save a lot of time." Li Xiu asked doubtfully.

"Idiot, if I can get out, what do I need you for..." The Great King seemed to realize that he seemed to have let the cat out of the bag, and the voice in Li Xiu's mind immediately stopped.

"So you can't get out. Then I have to dig it myself. Although it will be slower, as long as there is enough time, I should be able to dig out all the rubies." Li Xiu said.

Seeing that Li Xiu didn't notice the loophole in his words, the Great King immediately said arrogantly: "It doesn't matter if it takes a little longer, just do your best. I will never treat you unfairly. After the matter is completed, you will be my official little brother, and I will grant you the highest honor."

"I'll do it right away." Li Xiu turned around and prepared to leave.

Since this thing can't get out at all, there's no need to pay attention to it. It's two thousand meters underground anyway and can't affect the City of Light. Besides, it should know nothing about the City of Light.

If it knew about the City of Light, the map transmitted to Li Xiu's mind would not still be a stone mountain.

And looking at the other scenery on the map, it is slightly different from the current area near the City of Light. It must have been trapped here for who knows how long and has no idea of ​​the changes outside.

"Wait." Before Li Xiu left the underground space, he was stopped by the Peerless King again.

"What else do you want?" Li Xiu turned around and looked at King Gai Shi and asked, but he was thinking in his heart: "Is this guy afraid that I won't come back and wants to do something?"

"You are a weak human being. If you run into trouble outside, it doesn't matter if you die, but it would be bad if you delay my important plans." King Gai Shi said thoughtfully.

Li Xiu discovered that he had actually overestimated the intelligence of the Great King. This guy was not an ordinary human being, and his thinking could not be measured by human standards.

"Go and look under the pool. There should be a few scales there. Take them out and carry them with you. When you meet an enemy you cannot defeat, throw the scales at your enemy. It will have a miraculous effect." The Great King was depressed for a long time before he said hesitantly.

Li Xiu had already guessed something by listening to its tone.

I guess those scales were from its body, and I don't know who pulled them off. It's such an embarrassing thing that it's certainly too embarrassed to say it out loud.

Li Xiu came to the edge of the pond, looked at the coral-like plant and asked, "What is this plant?"

"Don't worry about what it is, don't touch it. Take the scale and get to work." King Gai Shi said hurriedly.

Li Xiu immediately realized that this plant must be a good thing, otherwise King Gai Shi would not be so nervous.

The water in the pool was icy cold, but Li Xiu had magic armor to protect him, and he had the Ice Heart talent and Ice Ashes skill, so he was naturally not afraid of the cold.

He jumped directly into the pool, causing a huge splash.

"Be careful not to damage the gem." King Gai Shi shouted anxiously.

Li Xiu immediately knew what the thing was called, and he did it on purpose, but he didn't expect that King Gai Shi would take the bait so easily.

He stayed away from the gemstone and tried to dive towards the depths of the pool, staying close to the edge of the pool.

The pool is not as deep as imagined, only about 20 to 30 meters deep, and coral-like gems are connected to the rocks at the bottom of the pool.

The rocks at the bottom of the pool were all grayish white. Li Xiu originally thought that the scales on the body of the Great King were so huge that he should be able to see them at a glance.

However, after a careful search at the bottom of the lake, three palm-sized jade-white scales were found. Li Xiu was very suspicious. How could a creature as big as the Great King have such small scales?

"Could it be that I am wrong, and these scales are not from the Great King, then whose scales are they?" Li Xiu searched carefully again, and found only these three scales, and nothing else. Then they slowly floated out of the pool.

"Are these the three scales?" Li Xiu asked the Great King while holding the scales.

"Yes, that's them. Next time you encounter danger, just throw them at the enemy." said the Great King.

"Does it need to hit the enemy? Will it explode?" Li Xiu carefully inquired about the function of the scales.

"No need, it won't explode. Just do as I say. Stop talking nonsense and go dig for rubies." The Great King urged again and again.

Li Xiu had no choice but to leave the underground space with the three jade scales. After coming out, Sha Chu and the others were still guarding the cave entrance.

"What's going on below?" Chu Jun asked hurriedly.

"The two workers are dead. There's no need to go down to look for them. There are very dangerous demons down there. No one is allowed to go down without my order." Li Xiu looked at Sha Chu and continued, "Give double compensation to the families of the workers who died. Build me a gate on this cave. The stronger the better. Then change the design. Mark out this small area separately and build it according to the standards of a vault. No one is allowed to approach here without my order. You must follow up on this matter yourself. Never let anyone go down into the cave again, lest the demons inside be released by them."

Now that Sha Chu had money in hand, he didn't waste any time talking to Li Xiu. He just responded and went to call someone to do the job.

"What kind of evil spirit is that down there? Is it really so scary that even you can't deal with it? Will the existence of such an evil spirit down there have an impact on our City of Light?" Chu Jun asked in surprise.

"I really can't handle it. I have never seen such a demon spirit in my life." Li Xiu was speaking the truth. He had really never seen such a stupid demon spirit.

"As for the impact on the City of Light, there shouldn't be any impact for the time being. I will find a way to resolve it." Li Xiu doesn't want to kill King Gai Shi yet.

Firstly, it was because they didn't know what level of demon spirit the Great King was. If it was a super spirit, it would be difficult to deal with. He didn't want to act rashly before Ximen Guan made his new demon suit.

Secondly, the Peerless King should not be any danger now, and maybe we can get some benefits from him, so there is no need to rush to deal with him.

Li Xiu took the three jade scales to find Ximen Guan, wanting Ximen Guan to help him figure out what kind of demon the scales came from.

Ximen Guan studied the scales for a long time but couldn't figure out what they were. He only knew that they were scales from a demon spirit, but he couldn't tell what kind of demon spirit it was.

He just told Li Xiu that after instrument testing, it was found that the three jade scales contained very strong energy, but the energy was very strange, sometimes strong and sometimes weak, and it was very unstable.

Such unstable materials are not suitable for making magic armor, so Ximen Guan lost interest in them and returned them directly to Li Xiu.

Li Xiu then described the appearance of the evil spirit and the gem species, but Ximen Guan had never heard of them, so he had to give up.

"Let's go ask Lao Dao when we have a chance." Li Xiu put away the scales and called Chu Jun and A Fei to go out together.

This time he did not bring Qin Shi with him, nor did he call the Ye brothers and sisters. That was because only the people he trusted the most could participate in this mission. He wanted to find the ruby ​​mine that King Gai Shi mentioned.

If there really is a ruby ​​mine, all money problems will be solved in the future. Even if it is not a rich mine, it should be more than enough to support a few demons.

If the ruby ​​reserves are large enough and the quality is good enough, the excess can be used to buy some instruments and equipment for Ximen Guan so that he can create more powerful magic equipment.

"Why did you bring us here?" Chu Jun asked in confusion as he looked at the valley with sparse vegetation.

"Dig for gems." Li Xiu looked around the valley and said, "You've been in the gem business before, so you should know something about gem veins, right? See if there are any ruby ​​mines in this valley."

"I'm in the business of finished gemstones. I rarely deal in raw gemstones. It's completely different from prospecting for rubies. How do I know if there are ruby ​​mines here?" Chu Jun also looked around the valley and asked, "Who told you that there are ruby ​​mines here?"

"I heard what the evil spirit below the cave said." There were no outsiders here, so Li Xiu told the story of his encounter with the Great King below the cave. The two were stunned after hearing what they heard, as they had never seen this kind of evil spirit before.

Not to mention seeing it, I've never even heard of it.

"Is there such a weird demon spirit?" Chu Jun said with a strange look.

"Don't worry about whether it's weird or not. How can we know now whether there is a ruby ​​mine under this valley?" Li Xiu said.

"If there really is a ruby ​​mine, we must not let any news leak out. This is the area between Guyue City and Hongsha City. If they find out, they will definitely come to rob it..." Chu Jun pondered and said, "How about this? Since we have confirmed that the gem mine is in the valley, we can find a few places to dig down. At most, we can dig a few more holes. If there is a gem vein, we will definitely be able to dig up the raw stone. At most, it will just be a waste of time."

Li Xiu had no other choice. There was no prospector around them, not even a trustworthy gem hunter. They were worried about asking outsiders for help, and none of them were willing to kill someone to silence them, so they could only dig by themselves.

Fortunately, they all have magic spirits in their bodies, and they can use the magic spirits as free labor, so they don’t have to do the hard work themselves.

So those demons were turned into laborers digging pits. If other trial participants saw that they were using the brilliant demons as miners, they would definitely scold them for wasting resources.

Fortunately, the demon's strength is much greater than that of ordinary people. His hands are more powerful than a shovel, so he can dig the hole very quickly.

The valley is full of rocks, and the soil on the ground is mixed with a large number of rocks, making it difficult for ordinary people to dig.

However, several demons dug several deep pits separately, and the stones they dug out were almost piled up into a small hill, but no original stones were found.

"Li Xiu, could it be that we have been deceived by the evil spirit? If there really is a ruby ​​mine here, we should be able to dig up some raw stones after digging for so long." Chu Jun said as he turned over the stones.

"Is the Great King pretending to be stupid? His acting skills are too good. If it were in the past, he would have won an Oscar." Li Xiu also had some doubts, wondering if he had been fooled by the Great King.

"Strange, come and see what this thing is?" Just when the two people were suspicious, the bandit who was directing the demons to dig a hole in the distance suddenly waved and shouted at them.

Both of them thought that the bandit had dug up the raw stone and hurried over.
