Li Xiu was a little surprised. After letting the demigod Setsuna and the Jedi Knight let go, he directly dug down along the edge of the thing.

After digging to a depth of one foot, a light suddenly appeared below. The light flickered, like a flash of lightning across the sky.

Li Xiu took a closer look and discovered that underneath the black substance was a transparent crystal like glass, and the flash was coming from inside the crystal.

After digging a few more times, there was still glass-like crystal underneath. From time to time, one could see lightning-like things suddenly appearing and disappearing, appearing and disappearing continuously, as if there were many lightning bolts growing and changing inside.

Chu Jun saw the strange scene here, but he did not run back to see, and continued to be on guard at the beach.

After a while, the demigod Setsuna and the Jedi Knight dug a big hole, and the thing was revealed intact.

It was a cylindrical object with a diameter of about fifty to sixty centimeters and a height of about one meter but less than two meters.

There is a section of black material wrapped at each end, like two lids sandwiching a cylindrical crystal container.

There were constantly winding lights flickering and tangling inside the crystal container, sometimes there were one or two, sometimes there were several, appearing in no regular pattern and no one could see what was producing these strange lights.

"What is this?" Li Xiu looked at it for a long time but couldn't figure out what it was.

Summon the Pink Nightmare and the Black Death as well, and let all the demons push the thing down together, and then push it out of the pit like a wheel.

This thing was very heavy. Even with the combined efforts of several demons, they were unable to lift it, and could only push it.

Fortunately, it was a cylinder. After they worked together to push it into the city gate, Li Xiu searched the beach again. After making sure that there was nothing else, he called Chu Jun back and lowered the city gate.

"What is this?" Chu Jun looked at this strange container and was completely confused. He couldn't tell what it was.

"I don't know what it is, but I feel that the energy of the light inside is very strong." Li Xiu said thoughtfully as he looked at the light that appeared and disappeared out of thin air in the container.

"Maybe it's a good thing. Let's take it back and study it slowly." Chu Jun said.

"I also want to take it back, but you also know that things from the trial ground must be able to be picked up before they can be taken back. Even the demigod Setsuna and the Jedi Knight can't lift this thing together, so how can we take it out?" Li Xiu said helplessly.

"Is it so heavy?" Chu Jun was shocked.

Although the levels of the demigod Setsuna and the Jedi Knight are not high, their strength is not small. The two demons can't lift it even with their combined strength. It is hard to imagine how heavy this thing is.

"If you don't believe me, try it." Li Xiu said, spreading his hands.

Chu Jun summoned out his two brilliant black death demons. No one knew what Chu Jun fed these two black death demons, but these two guys have now been promoted to C-level.

Two C-level demons, one on each side, grabbed the handles on both sides of the black lid and tried their best to lift the container. As a result, the two Black Death Demons were so tired that black smoke came out of their bodies, and the container showed no sign of leaving the ground.

"It's so heavy... It's a bit troublesome to take it back... If I leave it here, I don't know if it will still be here when we come in next time." Chu Jun was also depressed.

"It's better not to take such a risk if we can bring it back." Li Xiu pondered and said, "Do you think this thing fell from the ship?"

"It is most likely so. However, the broken ship is full of holes. If there is really such a thing shining inside, how come we didn't see it before?" Chu Jun expressed his doubts.

Li Xiu was also thinking about this problem. The light inside the container was as bright as lightning, and the broken ship was full of cracks. If it was really inside the broken ship, how could it not be seen?

"There are only two possibilities now. One is that it might have been blocked by something when it was inside the ship, so we couldn't see the light. Another possibility is that maybe this thing is not on the ship, but was dropped by the terrifying evil spirit in the Black Sea..." Chu Jun analyzed.

Although the second possibility Chu Ling mentioned was a bit far-fetched, it was not completely impossible.

"Let's think about how to bring this thing back." Li Xiu said to Chu Jun, "Let's call out all the demons and see if we can lift this thing up with their combined strength."

Upon hearing this, Chu Jun called out all his demon spirits. All his demon spirits only consisted of two black death demons and one dark blue knight.

Li Xiu also summoned the demons on his side. A group of demons surrounded the container. Some lifted it with their hands, some lifted it with their heads, and they actually lifted the thing up by shaking it.

But looking at the appearance of those evil spirits, the light on their bodies flickered and they looked very exhausted.

Bang!

Not long after it was lifted up, the demon could no longer hold on and the container fell down, leaving cracks on the black stone ground.

This scared both of them, but fortunately there were no cracks or damage on the glass-like crystal container, so they both breathed a sigh of relief.

God knows what would happen if this thing got smashed and the light inside leaked out.

"This won't work. We have to take those wooden boards back as well." Li Xiu thought for a moment, took out two rings and threw them to Chu Jun.

"Is this the magic ring of the Death Contract? Where did you get it from?" Chu Jun took the ring and looked at it, then asked hurriedly.

"I picked them up from the enemy. I was originally planning to find an opportunity to sell them. Now you can use them first. But don't use them in front of others. This thing is related to Changshengtian and cannot be used casually. If seen by people from Changshengtian, you will get into trouble." Li Xiu said.

Chu Jun nodded and said nothing more. If it were in the past, he would have asked questions to the end. But now that he trusted Li Xiu, there was no need to ask so many questions. He knew that Li Xiu was not the kind of person who would kill and rob for his own selfish desires.

After Chu Jun used the two magic rings, he found that one was a B-level lava stone man, and the other was a C-level demon snake man. The lava stone man was a brilliant magic spirit, and the demon snake man was a shining magic spirit.

The two men put part of the wooden board on the backs of the Masked Emperor and the Pink Nightmare, and the remaining wooden board was held by Chu Jun and his Chu Jun.

Li Xiu asked the Jedi Knights, the demigod Setsuna and his own Black Death to lift the container together.

As for Cupid Archer and White Night Demoness, Li Xiu did not summon them at all. Their power was very limited at E level and they could not be of much help.

"Can it be lifted like this? Should we give up part of the wooden board?" Chu Jun knew of course that it was impossible to lift the container with just these evil spirits.

"With the addition of my strength, it should be possible. You go back first and clear the space in front of the trial gate for me. Don't let others see this thing." Li Xiu walked to the side of the container, stretched out his hand to grab the semicircular handle, and tried it with a little force.

"Okay." Chu Jun didn't waste any words. He held the wooden board and blew out the longevity lamp beside him.

In an instant, Chu Jun and his demon spirit disappeared, leaving only Li Xiu and his demon spirit in the city.

After waiting for a while to give Chu Jun enough time to clear the area, Li Xiu estimated that the time was almost up. He took a deep breath and a faint white light emanated from his body. In that white light, there was a hint of blood.

This is the light energy from the Forbidden Spear of the Symbiotic Contract. With the blessing of the light energy of the Forbidden Spear, Li Xiu's strength suddenly skyrocketed.

This is the benefit of the symbiotic bond, being able to share light energy with the master.

Before using the light energy of the Forbidden Spear, Li Xiu's original quality was 1.2, and he had no other enhancements except for his skills.

After being blessed with the light energy of the Forbidden Spear, it was equivalent to Li Xiu possessing the blessing of glorious quality, and his power was far beyond usual.

This is why the demigod Setsuna can contend with high-level demon spirits, relying on the blessing of high-quality light energy.

Li Xiu carried one side himself, the demigod Setsuna and the Jedi Knight carried the other side, and the Black Death held the crystal on the side.

The skill imprints on the fingers emerged, emitting various strange light patterns. Li Xiu and the demon spirit worked together but failed to lift the container.

The light on Li Xiu's body changed again. In addition to the red light, there was also blue light in the white light. It was the shared light energy from the evil spirit card.

This is equivalent to two kinds of brilliant qualities of light energy blessing Li Xiu at the same time. Now Li Xiu's power is no weaker than that of the demigod Setsuna.

After all, the demigod Setsuna is already at D level. With various skills and the blessing of two kinds of glorious quality light energy, Li Xiu is no weaker than him. This is a quite scary thing.

The container kept shaking and was about to leave the ground, but it just fell short by a tiny bit.

A light flashed in Li Xiu's eyes, and the Ultimate Light was activated. His entire body was dyed transparent by the light. A terrifying force erupted, and he lifted up one end of the container by himself.

The demigod Setsuna, the Jedi Knight and the Black Death also desperately burst out their strength and lifted the container together.

The moment the container left the ground, Li Xiu blew out the Longevity Lamp and felt a darkness before his eyes. When he reappeared, he was already outside the Trial Gate.

Bang!

The container fell heavily to the ground, with a small part of it sinking into the ground, and the stone floor around it cracked like a spider web.

The light on Li Xiu's body had dissipated. He looked around and saw that there was no one else in the yard where the trial gate was located except Chu Jun. He breathed a sigh of relief.

Chu Jun got a large piece of thick canvas from somewhere and covered the container directly to prevent the light inside the container from being too dazzling and attracting the attention of outsiders.

"What should we do now?" Chu Jun looked at Li Xiu and asked.

"Go find the old official and let him see what this is." Li Xiu found a chair and sat down with some fatigue.

Using multiple skills such as Blood Boiling, Super Stimulation, and Fanaticism at the same time to stimulate his body and inspire his potential, the burden on his body is quite heavy. Now he just feels that all the muscles in his body are a little sore.

Chu Jun responded and dragged Ximen Guan over after a while.

"What do you want to do? I've already told you that my experiment is at a critical juncture and I can't leave now. Why do you have to drag me here? Can't you wait a while?" Ximen Guan was pulled over by Chu Jun, still complaining.

"Old official, look at what this is." Li Xiu pointed to a pile of wooden boards and said to Ximen Guan.

"What's so interesting about a pile of broken wooden boards?" Although Ximen Guan was somewhat reluctant, he still walked to the front of the pile of wooden boards, reached out and grabbed a piece of board, intending to pick it up and take a look at it.

But who would have thought that even though he grabbed with all his strength, he was unable to lift the wooden board.

Ximen Guan was stunned for a moment, then he looked at the wooden boards carefully. He picked up a palm-sized board and raised it in front of his eyes with great effort.

After looking for a while, Ximen Guan's expression gradually became solemn. He let go of his hands and let the wooden board fall to the ground, cracking the stone slab with a sound of metal and stone.

Then he squatted down again, tapped the wooden board with the metal ring on his finger, and listened attentively to the sound.

Then he took out a magnifying glass he carried with him and almost lay on the wooden board to look at it carefully bit by bit.

Finally, Ximen Guan even stuck out his tongue and licked the wooden board.

"Old sir, can you tell what kind of metal this is?" Chu Jun asked from the side.

"Bullshit metal, this is wood." Ximen Guan cursed without even raising his head.

"Is this really made of wood?" Chu Jun said in surprise. He thought this thing was made of metal.

"Where did you get these woods?" Ximen Guan raised his head, his eyes full of excitement.

"Don't worry about where we got it from. Do you know what this thing is?" Li Xiu asked Ximen Guan.

It would take half a day to explain it clearly, and Li Xiu just wanted to know what these wooden boards were.

"If I'm not mistaken, these should be magic wood..." Ximen Guan looked at the pile of wood on the ground and said with a strange look: "But it shouldn't be... so many magic wood..."

"What is the Demonic Wood?" asked Chu Jun.

"Just like its name, it is made of wood grown by evil spirits." Ximen Guan said.

"Can the devil also plant wood?" Chu Jun was greatly surprised.

"Of course you can. Catch a living demon spirit and transplant a sapling into its body. Let the sapling absorb the demon spirit's flesh and energy to grow until the demon spirit's energy is drained. The wood that grows is called demon spirit wood. Of course, that's not an ordinary sapling. Changshengtian cultivated some demon spirit wood in the past. I don't know where they found those saplings from."

"Those saplings are very special in themselves, as hard as iron and stone. After absorbing the energy of the magic spirits, the wood that grows is as hard as gemstones, and has the toughness of wood. It is the best material for making magic equipment..."

Ximen Guan said, his eyes sweeping over the pile of broken wood boards: "But Changshengtian didn't grow many magic woods at the beginning, and not every magic tree can be grown. Even if it can be grown, because the magic spirits used to grow the magic trees are different, the magic woods that grow are also somewhat different... These woods look exactly the same, and they are so big. If they are all magic woods, it is really hard to imagine what kind of magic spirits they grew from... Besides..."

"Besides what..." Li Xiu asked.

"If these woods are really magic woods, I feel that they are somewhat different from the magic woods I have seen in Changshengtian. They are probably of higher quality than those magic woods... Of course, the premise is that they are really magic woods." Ximen Guan looked at Li Xiu and asked, "Where did you get these woods from?"

"Black Death City." Li Xiu replied.

"Is there such a thing in Black Death City?" Ximen Guan was skeptical.

"How can we be sure whether these are demonic wood?" Li Xiu asked.

"That's easy. I'll take it back and test it and we'll know. It'll only take a few hours at most." Ximen Guan said as he wanted to take the sample back. He also wanted to know whether this was the Demonic Wood or not.

"Wait a minute, there's something else you need to help take a look at." Li Xiu stopped Ximen Guan and pointed at the strange container covered by canvas.

"Is there something else?" Ximen Guan walked over puzzledly and reached out to lift the canvas.

"This...what is this thing..." Ximen Guan looked at the glowing container and opened his mouth in surprise.

"This is the question I want to ask you." Li Xiu said helplessly.

Ximen Guan's expression changed. He ignored Li Xiu and lay directly on the container, staring at the flash inside through the crystal container without blinking. He muttered incoherently, "This is unscientific... How can light energy be generated out of thin air... How can light energy be generated without an energy source... No... No..."

Seeing that Ximen Guan was about to go crazy again, Li Xiu quickly winked at Chu Jun, who quickly stepped forward to pull Ximen Guan away. Li Xiu then covered the canvas again to prevent the flash from attracting the attention of people outside.

"Let me go...what are you doing...I'm the only one who can figure out that thing...If you don't let me see it, you're going to have kids?" Ximen Guan struggled to rush back.

"Old official, don't be anxious. You can take the things back to the laboratory and study them slowly. But we have an agreement in advance. You must inform me first when you get the results, and you cannot use these things for experiments without my permission." Li Xiu said.

"This..." The old official was a little unhappy.

Before he could say anything, Li Xiu said, "If you don't agree, go back and continue studying your magic suit. I'll keep these things for now."

"What's the point of keeping it...Okay...I understand..." Looking at Li Xiu's expression, Ximen Guan knew that if he continued talking, he would probably have no chance of getting these things, so he had to grit his teeth and give in.

He also knew that it was a bit disrespectful for him to use Li Xiu's materials for his own research without even saying hello, and it was all his own fault.

However, Ximen Guan knew very well in his heart that he would have to use these materials sooner or later, so he was not too panicked.

"Put these things into my experiment first." Ximen Guan immediately forgot about the unpleasantness just now and couldn't wait to take them back for research. This strange container really made him curious.

Li Xiu and Chu Jun secretly transported the things to Ximen Guan's laboratory. Fortunately, the container could be pushed over, otherwise they would not be able to find any means to transport it in the City of Light.
