Both mechas fly at low altitudes and both set automatic navigation modes.

In the mecha automatic navigation mode, the driver can also control the body's limbs to move slightly.

Lei Ao flew in the sky, trying to swipe his arms in the air and pop out the Yin and Yang swords, splitting the air ahead dozens of times, and fine-tuning the parameters of his body.

"In the future, this will be your exclusive mecha. Ordinary damage can only be repaired and used for some care. The mecha is limited in the Dragon Falling Continent. Once it is completely scrapped, the procedures for applying for a new mecha are very complicated!" Leng Duanmeng sent a message to Lei Aotian through the team channel.

"Oh, the feeling in the egg cabin of this physical mecha seems to be different. I seem to have become stronger." Lei Aotian replied with a smile.

I just act as my wife as my mecha car and no one can borrow it.

"If the power of driving a physical mecha is controlled well, it will be stronger than when fighting in the egg cabin. After all, in some cases, the limits of the mecha and the user's thoughts cannot be simulated!" Leng Duanmeng explained.

Feng Shisan sat on the shoulder of the Leng Duanmeng mecha. After flying for more than ten minutes, he gradually got used to the flight speed and altitude and was no longer afraid.

Two mechas rushed to the road overnight, flew continuously for several hours, and arrived at Tianxuan City before dawn.

A border city with a size of no less than the Imperial City of the Tianlong Empire.

In the air, Lei Aotian and Leng Duanmeng removed the autonomous driving mode of their respective mechas and flew around Tianxuan City for a while.

One side of Tianxuan City is close to the sea, the city wall is twenty meters high, and most of the internal buildings are from one to three floors.

"The wall of Tianxuan City was rebuilt in the later stage of metal. In order to improve its defense and resist external invasions, it's a pity that the demise of Tianxuan City comes from the inside. Let's land, let's go to Tianxuan City underground to check the teleportation equipment." The sound of Leng Duan Meng came from the mecha's team channel.

Lei Aotian activated the mecha's biological exploration device and scanned Tianxuan City.

There were no living people, and even the bodies were not found.

Landed on the lawn of the city lord's palace with Leng Duanmeng.

Feng Shisan also jumped off Leng Duanmeng's shoulders and moved his lower limbs.

"I won't be on the mecha from now on. I will fly all the way, and the wind will blow it to me!" Feng Shisan complained in a low voice.

It was not dawn yet, but the two Destroyers' third-generation mechas have night market functions, which does not affect investigations in Tianxuan City.

"Where are the corpses in Tianxuan City before?" Lei Aotian asked.

Lei Aotian recalled his predecessor's memory of Tianxuan City.

My predecessor has been away from Tianxuan City for six years. I have a little vague memory of the city and some impression of the environment in the city lord's palace where I live, but I have never been underground in Tianxuan City.

"It was completely destroyed by the warriors from the Doomsday World to prevent the remains of the seldom beasts from remaining in the corpse." Leng Duanmeng whispered.

Leng Duanmeng took the lead in controlling the mecha to a large warehouse in the backyard of the city lord's palace.

The warehouse gate was covered with the seal of the court.

Leng Duanmeng controlled the mecha to unseal the seal and pushed open the big iron door.

An empty warehouse, what looks different inside.

Lei Aotian thought about the memories of his predecessor and had no impression of this big warehouse.

Leng Duanmeng controlled her mecha, scanned the surroundings, and came to a large stone pillar, with the metal index finger on his right hand stretched out and lit it on the pillar.

Three depressions appeared on the large pillars one after another, and then the ground began to creak.

At the center of the large warehouse, two metal plates are separated, revealing a long underground staircase.

The stairs and stairs are very wide. It seems that when we were originally designed, we considered allowing the mecha to pass through. The height and width of the passage are not a problem.

As the metal plates open, white lights lit up on both sides of the channel, and heavy metal plates on both sides.

"Can my city lord palace be mobile and combat?" Lei Aotian asked Leng Duanmeng.

"No, because of some connections, Tianxuan City, which was built by the trial office, only strengthened the Tianxuan City wall and underground facilities, and did not place any firepower weapons." Leng Duanmeng said casually.

Lei Aotian was a little disappointed after hearing this. It seemed that his Tianxuan City was not as capable of fighting like the metal fortress of the Inquisition.

After walking for more than ten minutes, he kept walking down, getting deeper and deeper. Lei Aotian suspected that the bottom of Tianxuan City had been hollowed out.

Finally, I walked out of the end of the metal passage, and in front was a huge underground square, with many thick metal cylinders rising from the ground, supporting the metal top above.

"At this time, this is the channel for the world of Doomsday to give away matter. It seems that it has not been destroyed. I will check it again!" Leng Duanmeng said.

Lei Aotian felt very novel after seeing it.

The center of this underground square is actually a large roller coaster with a double-track construction.

The metal double track ring, circles and ends of the roller coaster track, leads directly to a closed metal gate.

At the starting point of the roller coaster track, a train similar to a high-speed rail was parked, with several large truck boxes in the middle.

There are locomotives in front and behind this train.

"I used this to transport material to your doomsday world before. Why do you do so many circular tracks?" Lei Aotian asked curiously.

Leng Duanmeng pointed to the track and explained, "For acceleration, although the space channel between the Dragon Continent and our Doomsday World is stable, it is difficult to carry a lot of material by relying on human power. When crossing the space channel, carrying more things will lead to great resistance. Doomsday World has developed and built this double-track shuttle train, which accelerates in the circular track, so that the train can enter the space channel at a fast speed enough to break the resistance of the space channel and carry more material. There are also protective measures in the train, which will not let the passenger die in a hurry. Of course, ordinary people will feel a little uncomfortable if they ride."

Lei Aotian looked at the roller coaster and wanted to give it a try.

Unfortunately, the metal door of the transmission channel at the end of the roller coaster is now closed, which is probably related to the fact that my father takes away the positioning crystal.

Now this roller coaster cannot be turned on.

Leng Duanmeng came out of the mecha, walked to several units placed at the start of the metal track, recalled the data, and pre-started it.

The roller coaster track lit up blue light, and the double-headed shuttle train floated up, but did not move forward, and fell back on the track a few minutes later, and the blue light on the track went out.

"There is no problem with the shuttle equipment. The seal of the space channel by the Heavenly Dao has also disappeared. Now the positioning crystal is missing!" Leng Duanmeng said, and she looked at the metal gate of the teleportation channel that was closed at the end of the track, with a little fear on her face, and she quickly shifted her eyes and didn't want to look more.

"Don't you want to go back to your hometown to have a look?" Lei Aotian also came down from his mecha.

"I don't want to!" Leng Duanmeng said briefly this time without explaining too much.

Feng Shisan, who was standing beside him, walked towards the shuttle train curiously.

"Don't touch it, there's still some electric current!" Leng Duanmeng raised her head and shouted immediately.

But it's too late!
