Both mechs flew at low altitudes, both with autopilot mode.

In the autopilot mode, the driver can also control the limbs of the mech to move in a small way.

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

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

"Oh, it doesn't feel like it's the same in the egg bay of this physical mecha, I seem to have gotten stronger." Lei Aotian replied with a smile.

If you use your mecha car, you can be your wife, and no one can borrow it.

"The power of piloting a physical mecha, if controlled well, will be stronger than in the virtual battle in the egg pod. After all, there are some situations where the limits of the mecha and the user's thoughts cannot be simulated in the egg cabin! Leng Xuanmeng explained.

Feng 13 sat on the shoulder of the Cold Dream Mecha, and after flying for more than ten minutes, he gradually got used to the speed and altitude of this flight, and was no longer afraid.

The two mechs traveled overnight, flying for hours on end, and arrived at the Chosen City before dawn.

A border city no less than the Imperial City of the Celestial Dragon Empire.

In the air, Lei Aotian and Leng Xuanmeng lifted the autopilot mode of their respective mechs and flew around the sky above the Chosen City.

The Chosen City is close to the sea on one side, the city walls are twenty meters high, and most of the internal buildings are one to three stories.

"The walls of the Chosen City were rebuilt in metal in the later period, in order to improve the defense against external invasions. It's a pity that the fall of the Chosen City came from within. Let's land, let's go underground to the Chosen City to check the teleportation equipment first. "The mecha squad channel, there is a sound of cold dreams.

Lei Aotian activated the mecha's biological detection device and scanned the Chosen City.

There were no living people, not even corpses found.

Landing on the lawn of the City Lord's Palace with Leng Xuanmeng.

Feng 13 also jumped off Leng Xuanmeng's shoulders and moved his lower limbs.

"In the future, I won't sit on the mecha, this flight, the wind will blow for me!" Feng Thirteen complained quietly.

It's not yet dark, but the two Destroyer third-generation mechs have a night market function, which doesn't affect the exploration in the Chosen City.

"What about the corpses in the Chosen City before?" Lei Aotian asked.

Lei Aotian recalled his predecessor's memories of the Chosen City.

The predecessor has been away from the Chosen City for six years, and his memories of the city are a little vague, and he has some impressions of the environment in the city lord's palace where he lives, but he has never been to the underground of the Chosen City at all.

"It was completely destroyed by the warriors from the apocalyptic world, so as not to leave the baby beast in the corpse." Leng Xuanmeng whispered.

Leng Duanmeng took the lead in controlling the mecha to a large warehouse in the backyard of the City Lord's Palace.

The door of the warehouse, with the seal of the Inquisition.

Leng Xuanmeng manipulated the mecha to unseal and push open the big iron door.

An empty warehouse, inside which looks different.

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

Leng Xuanmeng controlled her mecha, and after scanning the surroundings, she came to a large stone pillar, and the metal index finger of her right hand stretched out and lit it on the large pillar.

Three depressions appeared in succession on the large pillar, 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 staircase steps and passages are very wide, and it seems that when it was originally designed, it was considered to allow mechs to pass, and it was not a problem to walk four or five mechs side by side in the height and width of the passage

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

"My family's city lord's palace, can I move to fight?" Lei Aotian asked Leng Xuanmeng.

"No, the Heavenly Chosen City, which was built with the assistance of the original Trial, only strengthened the Heavenly Chosen City Wall and underground facilities due to some relationships, and did not place any firepower weapons." Leng Xuanmeng said casually.

Lei Aotian was a little disappointed after hearing this, it seemed that his Chosen City was not like the metal fortress of the Inquisition.

After walking for more than ten minutes, going down all the way, getting deeper and deeper, Lei Aotian suspected that the underside of the Chosen City had been hollowed out.

Finally out of the end of the metal passage, in front of me is a huge underground plaza, many thick metal columns, rising from the ground, supporting the metal roof above.

"Here, this is the passage to the apocalyptic world, it doesn't seem to have been destroyed, I'll check it again!" Leng Xuanmeng said.

Lei Aotian felt very novel after watching it.

In the center of this large underground square, there is a large roller coaster with two tracks.

Metal double-track rings, one in a circle, lead to a closed metal gate at the end of the roller coaster track.

At the beginning of the roller coaster track, a high-speed rail-like train is parked, with several large wagons in the middle.

This train has locomotives in front and behind.

"What did you do with this to transport materials to your apocalyptic world and make so many ring orbits?" Lei Aotian asked with some curiosity.

Leng Xuanmeng pointed to the orbit and explained, "Acceleration, although the space passage between the Falling Dragon Continent and our apocalyptic world is stable, it is difficult to carry a large amount of matter through it by manpower. When traversing the space passage, there will be a lot of resistance when carrying too many things. The apocalyptic world has developed and built this double-track shuttle train, which accelerates in the ring track, so that the moment the train enters the space channel, the speed is fast enough, it can break through the resistance of the space channel, and carry more matter. There are also safeguards in place inside the train to prevent passengers from dying in a hurry. Of course, if ordinary people take it, their bodies will also be a little uncomfortable. ”

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

It's a pity that the metal door of the conveyor passage at the end of the roller coaster is now closed, which is probably related to the fact that Daddy took away the positioning crystal.

Now this roller coaster can't be turned on.

Leng Jiemeng came out of the mech, walked to the several units placed at the beginning of the metal track, called up the data, and performed a pre-start.

The roller coaster track lit up with a blue glow, and the double-headed shuttle train levitated, but did not move forward, and after a few minutes, it fell back onto the track, and the blue light on the track went out.

"There is no problem with the shuttle equipment, the seal of the Heavenly Dao on the space channel has also disappeared, and now there is a lack of positioning crystals!" Leng Xuanmeng said, she looked at the metal gate of the teleportation channel closed at the end of the track, her face showing some fear, and quickly shifted her gaze, not wanting to look more.

"You don't want to go back to your hometown?" Lei Aotian also got down from his mecha.

"I don't want to!" Leng Xuanmeng said briefly this time without much explanation.

Feng Thirteen on the side walked curiously towards the shuttle train.

"Don't touch it, there's still some current!" Leng Xuanmeng looked up and immediately shouted.

It's too late, though!
