Chapter 434: Ancient Mine Road

"Gas bombs? Good idea, really good idea!"

Gao Gaotian smiled coldly.

"Against me, I will make your life worse than death!"

"Hurry up and get ready!"

Gao Gaotian ordered.

"No, son!"

Some private soldiers turned back and were gassed.

This gas bomb is also listed as a taboo by the military department in the Galactic Federation.

However, all major warlords will secretly develop poison gas bombs.

After all, this thing is extremely lethal, and it can also be used in some special environments to kill people invisible.

Nan Tian and Xue Yilao were like a strong "Great Wall", resisting the waves of attacks launched by Gao Aotian's subordinates.

In the mine tunnel, there are many corpses of Gaoaotian's private soldiers.

"It's not an option to fight like this. There are too many people in Gaoaotian. We have to find a way. Capture the thief first and capture the king!"

As Xue grew older, his eyes rolled.

"I can't kill it!"

Nan Tian immediately denied it.

Inside the mine, the roads are narrow and the space is limited.

The place where Gao Aotian was standing was quite far away from where Nan Tian and Xue Yilao were.

In this distance, there are layers of private soldiers, protecting Gao Aotian tightly.

In addition, the conditions of the mine are limited, and heavy weapons cannot be used to carry out devastating blows.

Nantian's "Taigu" spacecraft is basically useless.

It is too difficult and impossible to take the head of Gao Aotian among the ten thousand armies.

"As we fight, we retreat! That's the only way!"

Nan Tian said.

Gaoaotian's team is still increasing continuously.

Some private soldiers are also very strong, and they go up one after another.

Even though Nan Tian and Xue Yilao were both top players, they couldn't stand this kind of wheel battle.

Xue Yilao was the first to start to get scars on his body.

Later, Nan Tian also had several scars on his body.

At this time, Gao Aotian's gas bombs and some biochemical weapons were also ready.

One after another, low armored vehicles drove into the mine tunnel.

An officer came down and saluted Gao Gaotian.

"My lord, the gas bombs and biochemical weapons are all ready, just waiting for your order!"

"Ready? Are you sure about killing those three people?"

Asked proudly.

"Reporting son, there is absolutely no mission problem! At your order, I urgently dispatched 10,000 Z-type pestilence-gas bombs in stock, as well as thousands of biochemical cannons that can fire highly toxic substances."

The officer said triumphantly.

Gao Aotian nodded: "Okay, one milligram of Z-type plague poison can kill a million ninth-rank mecha warriors wearing A-type mechas. And in a poison gas bomb, at least Contains a hundred liters of toxic substances! Ten thousand gas bombs fired at once, it must be spectacular!"

"What the son said is absolutely true!"

said the officer flatteringly.

"My son, in order to ensure safety, you retreat first, and I will lead people to finish firing the shells, and then block the entrance of this mine."

said the officer.

"OK!"

Gao Gaotian smiled.

After receiving the order, Nan Tian and the private soldiers around Xue Yilao all retreated at once.

Nan Tian and Xue Yilao looked at it strangely.

"What's going on? How did these bastards retreat?"

Nan Tian was extremely puzzled.

"Yes, is Gao Aotian showing kindness?"

Xue Yilao was equally astonished.

Gao Aotian led most of the private soldiers to retreat.

In the mine tunnel, there is only one left, which is used to launch poison gas bombs -->>

Hundreds of armored vehicles, and thousands of biochemical cannons have been erected.

Armored vehicles and biochemical artillery lined up in the mine tunnel one by one, and blocked Nan Tian's way forward.

The officer was sitting in a main tank.

The officer and his soldiers had already put on special gas masks, and they had all swallowed antidote pills.

"Ready to launch! 123!"

The officer gave the order and pressed the fire button.

"Bang bang!"

Gas bombs, as well as the firing of biochemical artillery, were not so violent.

In the mine tunnel, only low voices echoed.

smoke!

There are also some powder dust, which also floated up.

The air in the entire mine tunnel became turbid.

Xue Yilao's complexion changed drastically.

Immediately, Xue Yilao cursed loudly: "The hateful and vicious Gao Aotian actually used poison gas bombs and some biochemical weapons! These things kill people invisible!"

"Master, this is poisonous gas! Extremely poisonous gas!"

Xiaoxing also reminded.

"The Meteor Mecha has automatically opened the air protection cover to isolate the poisonous gas!"

Xiaoxing reacted instantly.

In this poisonous gas, Nantian has Meteor Mecha, this heaven-defying mecha, and the dedicated Little Star, who assists it.

Nan Tian was in the poisonous gas, but he was fine.

However, Xue Yilao and Xiaoqing couldn't do it.

Xue Yilao and Xiaoqing were both wearing A-type mechas. In terms of protection ability, they were far inferior to the Meteor Mecha in the middle level.

Both Xue Yilao and Xiaoqing were infiltrated with poison gas to varying degrees.

Xue Yilao was able to hold on for a while after inhaling the poisonous gas because of his powerful mecha cultivation.

Xiaoqing can't do it.

The poisonous gas entered her body, Xiaoqing's whole body was black, and she was in danger.

"Go, the road ahead is also blocked by Gao Aotian and these bastards, we can only run backwards quickly! We must take Xiaoqing to a safe place!"

Nan Tian picked up Xiao Qing on his back, dragged Xue Yi old, and started running backwards.

The speed at which the poisonous gas diffuses is also very fast.

The UL-508 mine tunnel where Nan Tian and others are located was not the longest in the first place.

The gas bombs and biochemical artillery that Gao Aotian threw in were too many.

After a stick of incense time, the entire UL-508 mine tunnel is full of various toxic substances with extremely high concentrations.

Gradually, Xue Yilao couldn't stand it anymore.

"Young master, the old man is going to take a step first!"

Xue Yilao tilted his head and passed out.

Nan Tian knew that he couldn't delay any longer. It seemed that he could only bring Xue Yilao and Xiaoqing into his life realm, breathe fresh air, and relieve the toxicity.

It was the time when Nantian was about to take action.

Xiao Qing, who was on Nan Tian's back, moved her fingers in a daze, and accidentally touched a rock wall by chance.

"Branches!"

Suddenly, the land under Nantian's feet disappeared!

Nantian, Xiaoqing and Xueyilao all fell down.

"bump!"

Nan Tian landed, looked around, and found himself in a deep path.

Using the light on the Meteor Mecha to scan the surroundings, Nan Tian was startled.

Around this path, there are many bones.

Next to the bones are some rusty weapons.

There are also some ancient murals carved on the rock walls around this trail.

Everything here looks so old.

"I'm in a mithril mine. I saw these bones and weapons. Could it be that this deep and dark path used to be an ancient mine. It was used by the ancients to mine ore."

Nan Tian guessed.
