"This... this is..." Dugu Qiubai frowned, looked carefully, and then said: "These oils may be poisonous. Be careful and ask people outside to come in and fill in the place as well. This will be safer."

"Wait!" Chen Xiao squatted down and looked carefully, then stuck some black oil on his hands, put it on his nose and smelled it, and suddenly exclaimed: "Petroleum! This is oil! Be careful, step back one after another!"

After all, Chen Xiao is from the 21st century. Although he has never seen oil with his own eyes, he has always seen what it looks like on TV. With the smell of gasoline, no matter how dull it is, he can guess what it is.

According to the five elements of the gold, wood, water, fire and earth in Yu Ji's tomb, now the gold and wood have passed, and the rest are water, fire and earth. The water and fire barrier may be closely linked, oil and fire attack... Not to mention the five of them, even if there are five thousand people, they will be burned out.

"Oil?" Dugu Qiubai asked, "Do you know this thing?" No wonder Dugu Qiubai didn't know the benefits of this thing. After all, he was an ancient man. This oil is usually buried in a very deep underground place, which is normal that he had never seen it before.

"Well, this is called oil, also known as crude oil, which is a viscous, dark brown liquid, exactly the same as the appearance of these things." Chen Xiao pointed to the large pond of oil in front of him and said, "This oil burns when it encounters fire, and the fire gate is below this water gate. Once a fire is touched, the consequences will be unimaginable."

"Can you cause fire?" Dugu Qiubai's eyes lit up after hearing Chen Xiao's words.

He didn't forget that when Huang Rong saved them, he caused fire and oil to block the ordinary blood demons. If this oil could also be ignited, so much oil would be of great use!

"Well, that's why I said this thing cannot be buried with soil, it would be too wasteful." Chen Xiao smiled, then turned around and shouted to the back: "I asked brothers to prepare various utensils. The big pit dug out when filling the pit before was smeared with soil around it. Let's take oil and burn the demons this time! Haha!"

Chen Xiao's words are now prohibited. The more than 2,000 fellow workers in the world are completely following Chen Xiao's horse. After hearing his words, he immediately took out all kinds of utensils, wooden barrels, large pots and large ceramic bottles, and all the things that could hold water.

During this process, Chen Xiao was particularly harsh instructing him to be careful of open flames. If these oils are just a little bit, they will definitely not be able to touch them.

There were more than two thousand people, and even if each person only had a jar of oil transported it out, it would be equivalent to a small pool together. However, the oil in the water pass had transported it for more than 30 times before it was considered to be all transported. Chen Xiao went to the big pit loading the oil and smiled immediately. With so much oil, when he met Shen Lie, he would definitely be enough for him to drink a pot.

After getting the oil, the pit will be filled. Now everyone has already practiced it and makes perfect. This time, it only took one hour to completely fill the pit after the water gate was taken out of the oil.

Once the water barrier is broken, without oil as a burning substance, the fire barrier will naturally be no problem.

At this moment, there is only the last level, Thick Soil Level!

Chen Xiao and the other two took a deep breath. Now there was only the last level left. I don’t know what Xiang Yu would make to make things difficult for everyone. However, I didn’t expect that after walking not far from Huoguan, the terrain began to go downhill. After walking for a while, I actually arrived in a huge underground cave.

After Chen Xiao truly saw the things in the underground cave, he was completely shocked.

Twelve night pearls are inlaid on the walls around this underground cave. Of course, these are far from what shocked Chen Xiao. What really surprised Chen Xiao was that there were twelve golden metal villains under the night pearls!

Chen Xiao couldn't tell what material they were made of. They were about half a person tall, and were lifelike in all kinds of shapes, both men and women, and they all looked like waiters. On these metallic villains, next to those night pearls, there were also handwriting written by Xiang Yu himself.

"My name is Xiang Yu. I have been invincible for forty-five years. I found that these irons fell from the sky were cast into twelve gold men and guarding the mausoleum of my wife Yu Ji." "If outsiders can see my handwriting, remember that they should not disturb my wife's sleep, otherwise they will suffer a sudden disaster and will not have a good end. Remember, remember!"

"These..." Chen Xiao and others looked at each other, and took a deep breath.

Xiang Yu, the overlord of Western Chu, told him not to disturb Yu Ji's sleep. The meaning of naturally was that he would never move Yu Ji's coffin. Otherwise, he would inevitably suffer a sudden disaster. I think with Xiang Yu's ability, the punishment would be extremely serious.

The twelve gold men in front of them couldn't tell what metal was made of. Xiang Yu put them here, which meant to guard the tomb. However, Xiang Yu did not mention what would happen if the twelve gold men were taken away. I think the real mechanism should be in Yu Ji's coffin, and the twelve gold men should not have a big problem.

Dugu Qiubai summoned the sword energy and gently touched one of the villains. With a touch, he immediately said "Huh".

His invincible sword energy could not be cut off from these little golden men, which was really strange.

Chen Xiao and the others were not in a hurry to observe the twelve golden men, and walked into the room at the same time. When they got inside, there was a huge cave about seven or eight feet high. As the few people were about to enter, Dugu Qiubai looked up inadvertently and suddenly said in a deep voice: "No, retreat!"

Of course, no one would have any doubts about his words, and immediately withdrew from the cave. At this time, Dugu Qiubai said solemnly: "I understand what Xiang Yu meant by not having a good ending. The last earth pass is here."

"Above this cave is a mechanism. If what I expected is not bad, there must be a huge rock worth hundreds of thousands of pounds inside it! When we go in, we may not encounter any mechanism. If the big stone falls, we will have to trap here!"

It is very likely that Dugu Qiubai is worried about. Several of them are very well-versed people. After thinking about it for a moment, they immediately turned around and quit.

"Let's go back now?" Chen Xiao asked in a low voice.

Dugu Qiubai looked at the twelve golden men in the cave, thought for a while, and said, "You go out first, I'll try to see if there is any danger in moving the golden men. If there is really any mechanism, you can save me."

This is naturally a good idea. Chen Xiao and the other two left the cave and watched from afar. Under the glimmer of night pearls, each of Dugu Qiubai pushed and moved the position. After all the twelve gold men moved, everyone saw that there was no mechanism to touch them. They immediately used their internal strength, each of them was responsible for two to three gold men, and returned according to the original path. (To be continued.
