After that, Zhong Lingyu and the two invited Liu Yi to the City Lord's Mansion, and after arriving at the City Lord's Mansion, they handed over many medicinal materials to Liu Yi.

After Liu Yi accepted the medicinal materials, he began to refine the Heavenly Spirit Pill.

However, he just left it to the system to refine, and he always paid attention to the movements in the city lord's mansion.

A day later, he finally had a catch. I heard the city lord call Miss Zhong Lingyu. This made him confirm his previous guess that Zhong Lingyu was the daughter of the Marquis of Tsing Yi.

At noon, Liu Yi left his room and divided the packed pill into two parts for Zhong Lingyu and Qiao Juan.

After Zhong Lingyu and the two of them checked it, they exclaimed: "Sure enough, it is a perfect elixir, no matter how much you take such an elixir, you don't have to worry about any problems." ”

"When are you going to the forbidden land?" asked Liu Yi.

"This is going to trouble the city lord to lead the way. Zhong Lingyu said.

After that, call the lord of the city. Under his leadership, he came to the backyard of the City Lord's Mansion. Here, the lord of the castle went to move a stone table in the pavilion.

Then, I saw the wall in front of me move away. When the wall was removed, a cave was seen. There is still light in the cave, which is very mysterious. There is also a fresh breeze blowing inside from time to time, which makes people feel very comfortable.

"Let's go in!" Zhong Lingyu said.

The three of them walked into the cave, after a dozen steps. When they turned back, they found that the entrance was gone, and all they could see was a sea of bamboo.

In the bamboo forest, the breeze blows, and the sun shines brightly in the sky.

However, it was this place that seemed very comfortable, but there was no trace of aura, as if it had been emptied.

"Young Master Liu, be careful. It's hard to take care of each other and deal with each other carefully. Zhong Lingyu reminded.

As soon as the words fell.

"Bang!" "Bang!"

There was a burst of gunshots, and this sound made Liu Yi think that he had heard it wrong, because it was the sound of gunshots, machine guns.

Liu Yi quickly flew up, dodging the bullets, and stood in the air with the help of a bamboo.

Zhong Lingyu and the others did the same, standing up quickly to avoid these bullets.

At this moment, there was a sudden sound of propellers. Then I saw something like a spinning top flying over.

No, it's more like a UFO than like a spinning top. It's just that it's smaller, and there are sharp blades on it, and everywhere you go, the bamboo forest all falls. In an instant, Liu Yi and they had nothing to hide.

At this moment, there was a sound of footsteps.

Liu Yi saw a group of robots rushing over, these robots were athletic, and in just a blink of an eye, they surrounded Liu Yi and the three of them. Each robot holds a machine gun in its hand and carries a bazooka-like device behind its back.

"This is the wrong set, how can there be such a thing here?" Liu Yi scolded in his heart.

You know, these robots in front of him are even more powerful than what his world has seen in the news.

In this world, it is difficult to even generate electricity, and even make the most basic daily necessities, let alone make machine guns and robots.

However, there was not much time to think about it at this time.

Because these robots have already been dispatched, first there is a burst of strafing. Then a cannon blasted from behind.

Liu Yi and the three of them carried spiritual power in their hands, and all the attacks at the moment were blocked.

Although this offensive seemed to be strong, it was of little use to Liu Yi and them.

In front of spiritual power, even their shields can't be broken.

Liu Yi summoned the Chengying Sword in his hand and took the initiative to kill it directly, because he wanted to see how these robots worked.

The spiritual power on Liu Yi's body formed a shield, and the bullet hit it, only to hear a clanging sound, and then fell.

After Liu Yi got close, the Chengying Sword in his hand was quickly slashed, and one by one the robots were quickly disassembled by Liu Yi.

And Zhong Lingyu and the two did not slow down.

Each summoned their own weapons and quickly destroyed the robots in front of them.

After destroying the surrounding robots, Zhong Lingyu and the others wanted to continue to step forward, but Liu Yi did not, but stopped to check on these robots.

"Is Liu Gongzi interested in these puppets?" Zhong Lingyu said curiously.

"There is some interest indeed. Liu Yi said.

"Then let's stop and take a look! Zhong Lingyu said to Qiao Wan on the side.

Liu Yi checked it and found that these robots did use electricity, and they also used solar energy to generate electricity.

He checked it for a while and noticed that there was still text on it.

"Yanwu third spring!"

And Qiao Xuan, who came to see it, immediately said at this time: "The spring of the third year of Yanwu, the third year of Yanwu is the second year of Gaozu of the Han Dynasty, and it is the eighth year of the establishment of the Han Dynasty. ”

After Qiao Huang mentioned this, Liu Yi also remembered.

"Was it created in the early days of the Han Dynasty, is there such a high technology in this world?" Liu Yi said with doubts in his heart.

However, these things in front of him are indeed in front of his eyes, and it is impossible not to believe it.

They took apart several robots in a row, all of them, all produced in the same year.

"Take a look at it with the Heavenly Solution. Liu Yi said secretly in his heart.

He used his spiritual power to urge the Heaven Solving Machine, and soon, the path of these robots seemed to be replayed in his mind.

"Fairy Zhong, if you trust me, can you come with me? If you are busy, you can also leave first. Liu Yi said.

"It's okay, we're curious about these puppets, after all, we've never seen a puppet like this before. Zhong Lingyu said.

Liu Yi followed the path he knew and quickly returned.

After walking for about half an hour, Liu Yi and the others came to a cave.

The door of the cave is made of alloy, and it doesn't look like it's today's craftsmanship.

Liu Yi went over and summoned the Nine Palace Flames to directly melt the alloy gate.

When they walked in, Liu Yi found that there were electric lights, monitors, and other things that should not exist.

Liu Yi used his divine sense to sweep and quickly identified an office here.

He walked quickly, and where there was a door, he dissolved it with flames.

It didn't take long for Liu Yi to arrive at the office, and when he opened the office door, Liu Yi found a skeleton sitting on a chair here. It looks like he's been dead for many years.

On the side, there are also computers and even some documents.

"What are these?" Zhong Lingyu looked at these things, all of them extremely puzzled.

After all, even Liu Yi was stunned when he saw these things in this world.

He hesitated for a moment, then went over to look at the computer. Discovery is also able to open.

After turning on the computer, Liu Yi had a feeling that he had not seen for a long time.

There were a lot of documents hidden in it, and when Liu Yi opened these documents, the whole person stood there as if he had been struck by lightning.

"This ...... How is this possible?"
