The files in the computer record how these robots were built and obtained.

It took more than 30 years to collect the most advanced technologies from all countries on the planet and research them together.

If it were on Earth, it would certainly not be possible for more than 30 years.

However, these people are not ordinary people, and they digest it too quickly after learning those high-end knowledge. In addition, some monks even use deduction methods to study these technologies, so the speed of development is naturally rapid.

After completing a large number of robots, with a lot of high-tech equipment.

They began to look for places where these thermal weapons could be used. That is, if the spiritual power is imprisoned, and people cannot exert the spiritual power, then at that time, they can be tortured and killed.

However, in the last documentation, they ultimately failed.

With these technologies, it is impossible to fight their enemies, the heavens.

Gao Zu was furious, feeling that using these useless would only make people slack off their cultivation in the end. The researchers were ordered to destroy it.

Eventually, all the unused robots were left here.

And some of the researchers who came with them were unwilling to leave, and chose to die here. Here, it is a place of abandoned corpses, but it is not human corpses that are abandoned, but robots, those high-tech devices.

"Deal with the sky?" Liu Yi couldn't help but look up.

Heaven, what is it? Is it like the way of heaven that I have seen before, or is it someone who is stronger?

Why did Gaozu Liu Bang oppose the sky?

Another thing that shocked Liu Yi was that people in this world were able to go to the earth. Although the document does not specify how it went, it does say that these technologies and research methods were obtained on Earth.

And, he found a problem.

If it is true that he obtained these technologies on the earth, then when the earth has these technological levels, the time should be at most a few years different from before he crossed over.

Why is it that in a few years, it has become hundreds of years here? That's too fast, isn't it?

Liu Yi glanced at the skeleton next to him, this skeleton should be the one who left these documents.

In the end, he was reluctant to study these technologies by himself for decades, and finally chose to sleep with these technologies here.

"Let's go!" Liu Yi turned off the computer and said to the two.

"You seem to be quite familiar with this treasure, don't you take it with you?" Zhong Lingyu asked rhetorically.

"No, it's just useless. Liu Yi shook his head and said.

He has experienced a lot now, and he finds that the masters of the ancient times are all trying to fight against the heaven that he doesn't know what it is.

These technologies are useless to the heavens, and it is useless to bring them back, so it is better to concentrate on cultivation.

When you really need these things one day, you can find a way to return to Earth at that time. The people of this world can go to Earth, and he believes that he can find a way to go back.

And this key, he suspects that it is in the hands of Gaozu Liu Bang.

It's just that he doesn't know where Gaozu Liu Bang is now.

He knew that these mysteries could not be solved at once, and he needed to live longer before he had a chance to know more.

After leaving here, they walked quickly, and soon crossed the previous bamboo sea and came to a city.

In the sky above the city, Liu Yi saw a sky full of UFO-like flying objects, with blades on them.

This blade is not made of pure technology, but is combined with the forging methods of this world. Each blade is comparable to the hardness of a ground-level weapon.

As they came, the flying objects shone red light and flew towards them.

"You guys are dragging it out here, I'll fix it. Liu Yi said.

Naturally, these flying objects in this city were made by that researcher, and with the help of those robots, he was able to build a city here, and these things.

And the control center is also in the city.

Liu Yi had seen it from the document, so if he wanted to control it, it was naturally extremely simple.

"Good. Zhong Lingyu and the two nodded, for Liu Yi, she and the two of them could believe it.

Moreover, these treasures in front of them that they don't know, they can still deal with.

Liu Yi shuttled all the way through the wind, and directly shot down the approaching flying object with a sword.

Liu Yi quickly arrived at the center of the city and found the control center. There is also a computer here, Liu Yi clicked on the control program, and then selected the self-destructing program.

"Since you are going to abandon it, you should be decisive. Liu Yi muttered to himself.

At the same time, flying objects in the sky suddenly exploded, like fireworks.

Liu Yi walked out of here, and a Nine Palace Flame in his hand was freed up, destroying the entire control center in an instant.

Zhong Lingyu and the two arrived and said, "It seems that we are really looking for the right person when we ask Liu Gongzi to come in." Otherwise, these things are really hard to deal with. ”

Naturally, it was no problem to deal with them, but there were too many of them, and for them, it was very consuming of spiritual power.

It is very dangerous to consume a lot of spiritual power here.

After all, they know that danger is yet to come.

"I just saw it over there, but after here, the ones behind you need to be careful. Liu Yi said.

Walking through the city, Liu Yi saw from the documents that there was a swamp, and in the swamp, there was a kind of stone demon.

This kind of stone demon is extremely dirty, and those who touch it will lose their spiritual power in a short period of time. If a monk is unable to mobilize spiritual power, his fate can be imagined.

And the treasures here are behind the swamp, and there are nine treasures in total.

One of the most important is the core of this forbidden place, the treasure that seals the aura.

Locking Spirit Stone.

If the Heavenly Spirit Tree is a treasure that promotes people's cultivation, then this Lock Spirit Stone is the natural enemy of the Heavenly Spirit Tree, absorbing the spiritual energy and locking it.

Where the Lock Spirit Stone is located, the aura is completely absorbed and locked by the Lock Spirit Stone, which is extremely domineering.

As for the other eight treasures, three stones and five swords.

The three stones are the Phantom Moon Stone, the Sky Fire Stone, and the Elimination Stone.

The Phantom Moon Stone was originally taken out by the Pavilion Master of the Heavenly Machine Pavilion and Du Wei of the Valley of Ten Thousand Beasts. Both sides wanted to monopolize it, and as a result, they fought and finally reached a two-sided turn.

The Heavenly Fire Stone and the Elimination Stone were still inside, and as for the remaining five swords, they were five heaven-level swords. Heavenly Pole Sword, Earthfall Sword, Human Canal, Divine Sword, Ghost Spirit Sword.

Except for the lock spirit stone, the rest of Liu Yi wanted to take it away. Zhong Lingyu was booked, and he had no intention of turning against Zhong Lingyu.

After flying over the city, they saw a swamp.

A strange and unpleasant gas came out of the swamp, and it constantly made a sound of swallowing, which made people feel very disgusting.
