Without stopping long, Li Xiaobai asked the dolphin to continue diving, and the vertical descent speed of these helicopters was too slow to catch up with him at all.

In less than half an hour, the dolphin dived to its destination, the palace above the trench, which is also the end of the vertical waterway, there is an invisible energy membrane blocking the way.

It's very hard, Li Xiaobai tried it, it was much harder than the beetle of the purple gold beetle, it was estimated to exceed the SS level, no wonder no country or individual on the earth could enter here, it seems that there must be a corresponding "key".

The old man in white can conjure a palace out of thin air, and he can leave behind a magical vertical channel and energy membrane, and if he really doesn't want to be disturbed here, he can completely prevent any living beings from approaching. Especially the vertical waterway, Li Xiaobai suspected that the old man in white had even modified a certain part of the legal system, and the universal theorem of the universe, the gravitational force of the planet, had to be overshadowed in front of his old man, otherwise people like Chu Yunfei would definitely try the atomic bomb to bomb.

He just "locked" it up. It makes people greedy, and whether they can see or not, this is not a test.

So what is the "key" to open this door? As far as Li Xiaobai was concerned, he only took two books of cultivation exercises from the old man in white, and if there was a key, then for Li Xiaobai, the key could only be hidden in those two books of cultivation exercises.

Li Xiaobai put the little dolphin into the space, pressed one hand on the energy membrane, and the energy of the "Changchun Gong" was transmitted, but as expected, there was no reaction. The energy of "Wanmu Decision" was run again, and this time there was a vibration from the energy membrane, and an opening opened for Li Xiaobai to fall into.

The key to opening the door is to test the familiarity and use of the gift by those who have received it once. Li Xiaobai was lucky to pass the test.

Swam through the gate into the palace. The inside is the same as before. The hall was empty, Li Xiaobai took the two futons there, the old man in white and the eight paws used to sit on them and meditate, Xiaobai also said that these two futons are good things, as long as they are good things, it is not wrong, and there is time to study.

The futon texture is soft, and the cloth surface seems to be silk, and it is filled with something soft. It looks light, but the weight is not light, it is estimated that there are 180 pounds, and it shows that it is not simple.

It's just a little troublesome, he found that he can't enter the space in this energy membrane, the space here is blocked, and it's not a big problem to talk to Xiaobai...... That is, the two trophies have to be carried in their hands, which makes Li Xiaobai, who has long been accustomed to throwing everything in the space, very unaccustomed to it.

I went around the main hall again, and there was nothing relatively independent. There were treasures in the pillars of the main hall, but Li Xiaobai did not dare to destroy the pillars. It's bad if there is an attack reaction mechanic that causes the palace to collapse.

The four corridors lead to the other four side halls, and there are a lot of energy spars inlaid in the corridors for decoration, many of which are pure colors, losers, Li Xiaobai used his fingers to pick them, but he couldn't pick them off at all, so he had no choice but to give up. As for the four side halls, they are as empty as the main hall, and there is not even a futon.

In general, Li Xiaobai walked around the palace and only got two futons as trophies.

Putting two futons under his arms and coming out of the door of the main hall, the sound of helicopter propellers came from above, and the helicopters finally flew down and stopped above Li Xiaobai's head, these people can't pass the energy film.

Regardless of whether the people above could see it or not, Li Xiaobai waved his hand to say hello to them very stinky - his hand was clenched into a fist and a middle finger was flicked.

Swimming into the trench, glowing small underwater creatures still live here, but the appearance of the vertical channel above caused sunlight to enter this level of deep sea for the first time, and some of the small creatures could not adapt to death, leaving coral polyps-like calcareous corpses, and more adapted to it, and a little green appeared on the glowing little body.

The graves were all made of boulders, and the huge water pressure in the trench and the weight of the boulders themselves made it difficult for Li Xiaobai to push, and after more than an hour of busy work, Li Xiaobai opened a grave, but the old man in white just waved his hand.

For the old man in white, Li Xiaobai is still too weak now, everyone has gone to Mars, Li Xiaobai is still tossing things on the earth, and his realm and vision are not at the same level.

A huge sarcophagus, in good condition, with a simple fish and dragon pattern on it, may be the aesthetic relationship between civilizations, no matter how Li Xiaobai looks at it, he feels that the "dragon" on it is carved like a pig with scales.

There is a dragon pattern on the coffin, which indicates that the owner of this tomb has a relatively high status, and Li Xiaobai chose a relatively large tomb in this area for some reasons.

kowtowed a few times to the coffin, and said his sins, everyone is likely to be an ancestor, your predecessors have gone, and the funeral goods will be kept for the benefit of future generations, Amitabha.

The sarcophagus is a sliding structure, Li Xiaobai easily pushed it open, the coffin was covered with a simple energy membrane to block the seawater, and there was a corpse in a coarse cloth coat lying inside, the head and part of the sternum were missing, there were traces of burning, and it may have been shot in the head when it was at war with scientific and technological civilization.

The funeral goods were only a lump of black metal, the size of a fist.

"Xiaobai, can you scan it to see what it is?"

"No, the energy film on the coffin is blocking my signal wave, you need to take it out."

Li Xiaobai said hello, with the previous experience, the energy of "Wanmu Duel" was covered in his hand, and his arm penetrated into the energy membrane. didn't disturb the peace of the seniors, just scooped up the piece of metal.

"And now? Look. ”

"Wait, scanning...... It seems to be a rare metal called LGH in the universe, and no, it has had a long-term chemical reaction with something, and you see that it has a lot of bubble-like holes on its surface. ”

"The essence of Ugin that has been soaked in the cold pool for thousands of years is legendary?"

"Your analogy is good, according to the ancient cultivation civilization, it is estimated to be very close."

"And what's the use of this LGH metal?"

"It is very versatile, it has an ultra-high melting point and steel hardness, and the temperature of the core of the neutron star cannot melt it, making it a good material for melee weapons."

"But that's all." Li Xiaobai grabbed this piece of LGH metal and said depressedly, it's good, but it's ...... That's too little, isn't it?

Xiaobai said speechlessly: "User, please pay attention to your discipline, do you know how big the largest piece of LGH metal that Dr. Lu Dao Z has ever handled?" ”

"How old?"

"Less than 1/2 of your piece, plated on the melee weapon of the Flesh Machine Zero model, do you want to use LGH metal directly to forge weapons? Searching for ten galaxies won't satisfy you. ”

"Well, it turns out that I'm richer than Dr. Z."

As a joke, the thing was taken away, Li Xiaobai closed the sarcophagus for his predecessors, and rebuilt the tomb with a boulder, which was a natural move, but he didn't want to, an illusory light and shadow suddenly appeared in front of Li Xiaobai.

It's an old man in white.

"Ancestor, are you back?" Li Xiaobai was startled and blurted out subconsciously.

"It's not a real person, it's a 3D stereo radio wave."

"Phantom?"

The phantom said: "The junior is good, the first to pass, and you know how to respect the predecessors, I will allow you to open an additional grave, and then leave quickly." After saying that, he just disappeared.

Sure enough, it's a phantom.,It seems that whoever is the first to pass through the energy membrane and restore the tomb after taking the things in the tomb will be excited.,According to the meaning of the words,Everyone is only allowed to take the things of one of the tombs.,Many,Hehe,The old man in white has a way to kill him even if he is not there.。 Li Xiaobai had a guess about this rule from the beginning, so he chose a large tomb.

It is lucky to be able to take one more, the trench is not wide, hundreds of meters, but it is very long, stretching for tens of kilometers, the grave does not know the geometry, and the style and structure of most of the graves are similar, the graves damaged by geological movements in the past were either repaired by the old man in white or opened by the old man in white and emptied.

Li Xiaobai swam in the trench for a long time before he determined his goal.

Next to the wreckage of a huge technological civilization warship, there is a tomb that is not only large in size, but also has a rather peculiar shape. (To be continued......)
