Global Plunder: Start with Heart of Darkness

"City Master Gu, this is indeed a gas spring, but it is not pure. I suggest not letting ordinary soldiers get close to it. If you inhale too much, there may be problems."

Swann pondered for a moment before speaking in a deep voice. His eyes fell on the corpses of the goblins.

Gu Yu's face changed slightly, and he immediately sensed it carefully, and sure enough he found that the green gas he inhaled into his body not only contained highly active energy, but also had a weird smell.

This breath is very subtle. If he hadn't been promoted to Silver, it would probably be difficult to detect.

As he inhaled more gas, the breath grew stronger, became a little manic and violent, and began to try to invade his brain and heart.

However, Gu Yu's spiritual energy was now very powerful, and under the control of his consciousness, he quickly wiped out that weird aura.

But Gu Yu was not very happy because he realized that it would be difficult for people with less than silver level strength to remove harmful substances from the gas by themselves.

"Liu Qing, Mei Ninghua, all of you who are below the silver level, please retreat a hundred meters away." Gu Yu's expression changed and he immediately cleared most of the people.

Although Liu Qing and Mei Ninghua were a little dissatisfied, they understood that Gu Yu was thinking about them, so they evacuated with a large number of their men.

At this moment, the only ones left in place were Gu Yu, Ajit, Swann, Latte and Spider Queen Black Pineapple.

Black Pineapple is the only one in the Blade Spider clan who has broken through the limits. After the racial civilization was upgraded to Silver, her strength successfully reached the third level of Silver.

Black Pineapple's dream of being the master of the family has gone further and further away from him.

"Mr. Swan, do you know about the gas springs? Can you tell me about it?" Gu Yu was keenly aware that Swan might know the gas springs very well.

"Gas spring is a very pure gas energy. It can not only be used as raw materials for military industry, but also can strengthen military units and even produce mutants."

Swann spoke directly without hesitation.

Living in Dark Sky City these days, he has a good impression of the young city lord and is willing to provide some help.

"You mean this kind of gas can directly transform the body?" Gu Yu was shocked. This is much more powerful than those wood ore mines.

"Yes, if it is a pure gas spring, it is indeed a precious mineral." Swann nodded.

"Then do you think the gas spring here is polluted?" Gu Yu caught the meaning of Swann's words.

"This requires further testing, but judging from the death of these goblins, it seems that they have inhaled some kind of neurotoxin, which made them crazy and bloodthirsty."

Swann said with certainty.

"Mr. Swan, thank you very much for the reminder!" Gu Yu took a deep look at Swan and immediately gave instructions to Yingyi.

With the current level of civilization in Dark Sky City, it is difficult to test gas and analyze its components, but Gu Yu only has one way to quickly achieve his goal.

It didn't take long for the Shadow Thorns to capture a few goblins, bite each one with a piece of iron, and bring them to the edge of the gas spring.

Gu Yu silently observed the performance of these goblins.

Time passed minute by minute, and ten minutes passed in a flash.

As a large amount of gas was inhaled, the goblin who was originally screaming in terror gradually calmed down, his breathing began to become heavier and heavier, and his eyes became fierce.

After a while, the goblins began to roar threateningly, and rushed towards Latte with their teeth and claws bared, completely ignoring the difference in strength between them and attacking desperately.

Now not only Gu Yu and Ajit, but also Mei Ninghua, Liu Qing and others in the distance realized that something was wrong, and everyone's expressions became solemn.

"Go and catch some stronger ones." Gu Yu said while observing.

This time Ajit personally led the team and captured several fourth-level bronze wasteland cattle.

These huge wasteland cattle have a docile temperament and delicious meat. Many forces will capture and tame them, and there are some near Dark Sky City.

The waiting time was longer this time. After breathing gas for an hour and a half, the Wasteland Cow gradually began to show abnormalities.

They began to become turbulent and became more and more irritable, acting almost like goblins.

Gu Yu also noticed a detail. The skin of these wasteland cows was originally gray, but after inhaling excessive gas, it slowly turned green.

Three hours later, the Wasteland Cow could no longer suppress it and began to attack all creatures it could see.

However, after Lao Ai and Latte knocked them down, they somewhat restrained their murderous intent, but their eyes were still unruly, always looking for opportunities to counterattack.

Gu Yu had to knock them all out and take them away from the gas spring.

However, neither the goblins nor the wasteland cows returned to normal just because they stopped inhaling the gas. They were still crazy.

Gu Yu didn't know how long this abnormal state would last, whether it was a day, a month, or a lifetime.

Therefore, he ordered all the creatures who had inhaled excessive gas to be held in prison and observed slowly.

This gas spring was strictly blocked by him and no one was allowed to approach without authorization.

By the time he returned to Dark Sky City, the exploration team had discovered seven gas springs within a radius of a hundred miles. Including the earliest one, there were eight in total.

This is their initial discovery. As the scope continues to expand and the search becomes more detailed, this number will increase several times.

Gu Yu was secretly shocked. It seemed that the appearance of the gas spring would definitely cause a terrible storm.

Although he still doesn't know what this storm will be, he knows that the Hand of Judgment and the Flame Rose will probably not fight.

If there are enough gas springs, who would still want to play around with them?

The messages in the chat channel also verified his idea.

After half a day of deliberation, the news of the gas spring has completely spread.

More and more people are beginning to study this new energy mine, and have discovered various strange effects, announcing them in the chat channel.

"Hahaha, my homemade gun has been upgraded. Now I can make a gas rifle. The prosperous era of human civilization is coming!"

"It turns out that gas is a far more efficient energy source than oil. With it, our civilization will soon be able to upgrade, and by then we will be able to build cars, tanks, and airplanes."

"What does the technology you master mean? The powerful arms in this world cannot be dealt with by modern technological weapons."

"Support upstairs. Since inhaling the gas, my spearmen are now much stronger and extremely ferocious. Their combat effectiveness has increased by at least 30%."

"Me too. My gargoyle is now invulnerable and powerful. It can tear apart as many planes and tanks as it can."

"You are all idiots. Didn't you realize that we can also inhale gas? I feel extremely powerful now and can kill any monster!"

…

Occasionally, there are one or two calm people who point out that this kind of gas may have hidden dangers, and call on everyone not to be too aggressive and to explore slowly.

Unfortunately, this kind of alternative speech was quickly submerged in the wave of applause and did not attract many people's attention.
