At one o'clock in the afternoon of the next day, the pollution outbreak in the cave world stopped, and at about three o'clock, Chen Bing and Amethyst came to the entrance of the cave where the pollution broke out.

Only a slight black-green mist emerged from the entrance, which in the condition of the Tron Machine was already a slight level of contamination that would not disperse far away.

In many places on the Tron Machine, there is permanent pollution at the geological level, and even if you try to clean it up, it only takes a heavy rain with heavy pollution to make the pollution worse.

"Got in."

Chen Bing put on the obsidian exoskeleton armor, picked up the amethyst, and jumped inside from the hole.

The cave is sloping downward, and there are many footholds.

Previously, Amethyst and her sisters explored deep into the underground cave, and they could only use the rope to slowly walk inward, and their movement speed was quite slow.

Chen Bing didn't have this restriction, he directly spread out his mechanical wings and flew down, and his speed was dozens of times faster than that of Amethyst and them.

In less than thirty seconds, Chen Bing was holding the amethyst deeper than a thousand meters underground.

The pollution inside the cave began to increase severely, and with the naked eye, Chen Bing could no longer see the scenery ten meters away.

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

"From here, the pollution can become deadly."

Amethyst reminded.

Not only had she been with Malachite, but Ivy had also acted with her.

But when you come to this area, the body of the ivy will be eroded by pollution and will have to retreat.

"Warning, heavy toxic contamination has been detected in the air!"

The intelligent AI then issued a warning.

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

"Extradimensional Computing Mode."

Seeing this, Chen Bing immediately entered the extra-dimensional operation mode, the air shield defense system was running to the maximum, and his whole body was wrapped in a stream of black metal.

"Warning, the Phantom Mechanical Wing has been severely eroded, and it will be damaged if it continues to go deeper!"

Chen Bing continued to go deeper, and the intelligent AI warned again.

"Except for the mechanical wings, what is the condition of the rest of the components?"

Chen Bing immediately asked.

"Obsidian alloy has the property of resisting erosion, and with super memory alloy, it will not be affected by erosion."

Intelligent AI answers quickly.

"Then retract the mechanical wings."

Chen Bing landed on a stone beside him.

The Phantom Mechanical Wing was obtained from Cindy, and although it was a good thing, the material was not obsidian and could not withstand the erosion of pollution.

The mechanical wing retracts back into the back of the exoskeleton armor, and the air shield defense system covers it slightly, hiding the mechanical wing underneath.

"Then we had to slow down."

Chen Bing said to Amethyst.

Having said that, compared to the speed of Amethyst, Chen Bing's falling speed was still much faster.

He jumped from one stone to another, and with each jump, he could drop more than ten meters.

"Be careful, a little further down is the area where we're being guarded by the machines."

After about ten minutes, Amethyst reminded.

"Got it!"

Chen Bing replied that in the scanning system of the obsidian exoskeleton armor in China, the scan data of several mechanical monsters had already appeared.

You can't use weapons here, and the weapons will be eroded and damaged when you take them out, and if you accidentally get attacked, the air shield defense system may also be damaged, which will cause fatal damage to him, so Chen Bing doesn't plan to entangle with these mechanical monsters, he is ready to break through with speed.

【Enemies Spotted!】 】

[Attack the intruder!] 】

Chen Bing was quickly discovered by the mechanical monsters, who all raised their weapons and launched an attack on Chen Bing.

Chen Bing didn't intend to get entangled, he suddenly increased his speed and flew past these monsters.

……

"General Orson, intruder found in exhaust hole 4! One is a human adventurer who has escaped from a futuristic city, and the other is the Gem Clan we are looking for! ”

The bottom of the Cavern world.

Just like the king and the demon god on the Tron mechanical planet analyzed, there is no cave here.

Tens of thousands of meters deep underground, there is a huge mechanical city.

There are not too many mechanical buildings, but the entire mechanical city is not composed of black and gray mechanical instruments, and only in the middle of the mechanical city is there a large research room.

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

A large amount of black-green smoke erupted from the mechanical sphere, obscuring the sky.

The contamination that envelops Tron was born from this mechanical sphere.

The polluted smoke ejected from the mechanical sphere did not sink to the ground, and all of them were sucked into the six large openings above the cavern.

Two large and four small, they are the exhaust holes that excrete pollution.

"The No. 1 main exhaust hole, the No. 2 main exhaust hole, the No. 3 exhaust hole, and the No. 5 exhaust hole have all found intruders, all of whom are fugitives from the future city!"

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

"Except for the intruders in the No. 4 exhaust hole, the guards of the rest of the exhaust holes are all dispatched to stop the intruders as much as possible! Set up guards under Exhaust Hole 4, and when they come, attack with all your might to make sure you grab that Jewel Clan! ”

General Orson said lightly.

Chen Bing and the others used the space teleportation instrument in the third laboratory to escape, and Aosen, as a mechanical clan, naturally noticed it at the first time.

If they were other enemies, they could only watch Chen Bing and them leave, but Aosen and the others chased after them after a little preparation.

For the mechs, Tron was not a secret place, just one of the many places where they conducted their experiments.

Tron Mechanic is almost an experimental planet in a free-range state, this mechanical city is only maintained by a few mechanical people who have received orders, and every ten years, a status report will be sent back to the mechanical family, and there are no special circumstances, this report will not even enter the eyes of the mechanical family's high-level management.

After Aosen chased after him, he couldn't find Chen Bing and the others at the first time, but in the research room, he found the sapphires that had been attacked into pieces and were in a sleeping state.

Sapphires haven't been on Tron Mechanic for too long, and reports about them haven't been reported to the mechs.

Orson came over, naturally checking the recent report first, trying to find Chloe and Chen Bing.

Then Orson found reports that sapphires were not corrupted by contamination, and after a little research, Orson noticed a startling possibility.

If he can catch more Gem Clan and conduct thorough research on the Gem Clan, it is possible for the mechanical lifeform to evolve to a new level!

For this reason, even the capture of Chloe was put aside by Orson, who launched a pollution outbreak and sent the mechanical guards out to capture the Gem Clan.

According to Ao Sen's analysis, as long as he can catch 6 gem people, it is enough to analyze the data he wants, and now he has caught five, Chen Bing and Amethyst came down from the No. 4 exhaust hole, and they fell into his arms.

(Khan, there are very few readers of this book who can follow the current chapters, and I didn't expect it to be reported...... The classmate who reported it raised his noble hand, he couldn't afford to toss, thank you! ）
