At around 1:00 p.m. the next afternoon, the pollution outbreak in the cave world stopped. At around 3:00 p.m., Chen Bing and Amethyst came to the entrance of the cave where the pollution outbreak occurred.

Only a slight black and green mist emerged from the entrance. In terms of the Tron Mechanical Star, this is already a slight pollution and will disperse if it doesn't float far away.

In many places in Tron Machinery Star, there are permanent pollution at the geological level. Even if you work hard to control it, just a heavy rain of severe pollution can intensify the pollution again.

“Go in.”

Chen Bing put on Obsidian exoskeleton armor, picked up the amethyst, and jumped into the hole.

The cave is slanted and rugged, with many places to settle down.

Previously, Amethyst and the others went deep into the cave to explore, and could only use ropes to slowly move in, and the movement speed was quite slow.

Chen Bing had no such restrictions. He directly spread his mechanical wings and flew downwards, which was dozens of times faster than Amethyst and the others.

In less than thirty seconds, Chen Bing carried the amethyst deep into the ground with more than a thousand meters.

The pollution in the cave began to worsen seriously. With the naked eye, Chen Bing could no longer see the scenery ten meters away.

The scanning system of Obsidian exoskeleton armor can be used, but the scanning range is also greatly weakened and can only scan to more than 200 meters away.

“From here, pollution can become deadly.”

Amethyst reminded.

She has not only come with malachite and the others, but Changqing Teng has also acted with her.

But when you come here, the Changqing Vine's body will be polluted and eroded and have to retreat.

『Warning, severe and highly toxic pollution was detected in the air!』

Smart AI then issues a warning.

When the warning was raised, Chen Bing flew inward for a while, and red spots appeared on his body and arms, expanding at a speed visible to the naked eye.

"Super-dimensional computing mode."

Seeing this, Chen Bing immediately entered the super-dimensional computing mode. The Qi Shield Defense System was maximized, and his whole body was wrapped in a stream of black metal.

"Warning, the Phantom mechanical wings are seriously eroded, and continuing to go deeper will be damaged!"

Chen Bing continued to go deeper, and Smart Ai warned again.

"How is the condition of the rest of the components except the mechanical wing?"

Chen Bing asked immediately.

"Obsidiary alloy has the characteristics of resisting erosion, and will not be affected by erosion with super memory alloy"

Smart ai answers quickly.

"Then take back the mechanical wings."

Chen Bing fell down on the stone beside him.

The Phantom Mechanical Wing was obtained from Cindy. Although it is a good thing, the material is not an obsidian alloy and cannot withstand the erosion of pollution.

The mechanical wings retracted to the back of the exoskeleton armor, and the coverage of the air shield defense system was slightly increased, hiding the mechanical wings below.

"Next, we'll slow down."

Chen Bing said to Amethyst.

Having said that, compared with Amethyst and the others' speed, Chen Bing's whereabouts are still much faster.

He jumped from one stone to another, and he could fall for more than ten meters every time he jumped.

"Be careful, go a little further and there is the area where we encounter the mechanical guard."

About ten minutes later, Amethyst reminded me.

"knew!"

Chen Bing replied that in China, the scanning system of Obsidian exoskeleton armor, there have been scanned data of several mechanical monsters.

Weapons cannot be used here, and the weapon will be eroded and damaged when taken out. If it is accidentally attacked, the Qi Shield Defense System may be damaged, which will cause fatal damage to him. Therefore, Chen Bing does not intend to entangle with these mechanical monsters, and he is ready to break through with his speed.

【Discover the enemy!】

【Attack the invader!】

Chen Bing was soon discovered by those mechanical monsters. They all raised their weapons and launched an attack on Chen Bing.

Chen Bing did not intend to worry, but suddenly increased his speed and flew past these monsters.

...

"General Orson, exhaust hole No. 4 discovers the invader! One is a human adventurer who escaped from the future city, and the other is the target Gem clan we are looking for!"

The bottom of the cave world.

Just as the king and the demon god on Tron Machinery Star analyzed, there is another world here.

Under the ground tens of thousands of meters deep, there is a huge mechanical city hidden.

There are not many mechanical buildings, but the entire mechanical city is not composed of black and gray mechanical instruments. Only in the middle of the mechanical city can there be a larger research room.

In the air of the mechanical city, a huge mechanical ball was hung in the air by a huge chain of various directions.

A large amount of black and green smoke ejected from the mechanical ball, covering the sky and the sun.

The pollution that enveloped Tron mechanical star was born from this mechanical sphere.

The polluted smoke ejected from the mechanical balls will not settle down to the ground, and they are all sucked into the six huge holes above the cave.

Two large and four small, they are exhaust holes for exhaust pollution.

"The intruders were found in the No. 1 main exhaust cave, the No. 2 main exhaust cave, the No. 3 exhaust cave, and the No. 5 exhaust cave, all of them were fugitives from the future cities!"

In the research room, the intelligence assistant reported to Orson urgently.

"Except for the invaders of exhaust hole No. 4, the guards of the other exhaust holes are all dispatched to stop the invaders as much as possible! Arrange guards under the exhaust hole No. 4, and when they arrive, they will attack with all their strength to ensure that they can grab the gem clan!"

General Orson said indifferently.

Chen Bing and his team escaped using the space teleportation instruments in the third research room. As a mechanical clan, Orson naturally noticed it immediately.

If it were another enemy, I could only watch Chen Bing and the others leave, but Orson and the others chased after a little preparation.

For the mechanical race, Tron Machinery Star is not a secret place, but just one of their many places to conduct experiments.

Tron Machinery Star is almost an experimental planet in a stocking state. Only a few mechanical tribes who have received orders are maintaining this mechanical city. Every ten years, a status report will be sent back to the mechanical tribe. There is no special situation, and this report will not even enter the eyes of the senior management of the mechanical tribe.

After Osen chased after him, he failed to find Chen Bing and others as soon as possible. Instead, he found sapphires that were attacked into pieces and were in a sleepy state in the research room.

Sapphire and the others have been to Tron Machinery Star for too long, and the reports about them have not been reported to the Machinery Clan.

When Orson came over, he naturally checked the recent report first, trying to find out Chloe, Chen Bing and others.

Then Orson discovered a report that sapphire is not contaminated and eroded. After a little research, Orson noticed an amazing possibility.

If he can catch more gems and conduct thorough research on gems, the mechanical life forms may evolve to a new level!

For this reason, even the arrest of Chloe was put aside by Orson. He launched a pollution outbreak, letting the mechanical guards go out and arrest the gemsmen.

According to Orson's analysis, as long as he can catch 6 gem clans, it will be enough to analyze the data he wants. Now he has caught five. Chen Bing and Amethyst came down from the No. 4 exhaust hole, hitting his mind.

(Shan, there are very few readers who can follow this book so far, and I didn’t expect to be reported again... The classmate who reported it was so proud that he couldn’t afford to make trouble, thank you!)
