Thus, Lin Yifan and his team hurriedly used Qinggong to jump down; they slipped into the enemy's interior before the enemy arrived.

The steel plate above the launch shaft must be movable, or able to be opened outward, since whenever the arms organization wanted to launch a large missile, the grassy area above would definitely change, revealing the entrance to the launch shaft.

It was precisely because of this that the steel plate covering the shaft entrance was made of thinner, tough steel; because thick steel plates are too hard to move, the arms organization would not engage in such thankless, labor-intensive tasks.

However, it was this design that gave Lin Yifan and his team an opportunity to exploit.

Actually, one can't blame them, as normally such tough steel plates are impossible to break through; it's just their bad luck that they now faced extraordinary people.

After hearing the alarm, the arms organization's personnel realized that something serious had happened; so they quickly put on gas masks and protective suits and began to execute their final attack plan—a biological weapon attack.

Meanwhile, after entering the missile launch shaft, Lin Yifan and his team quickly found an iron door.

This iron door should lead to the arms organization's underground base; thus, without a word, they opened the door by the most savage, violent means.

"Boom!"

Instantly, the iron door fell, and Lin Yifan and his team stepped on it and swiftly walked in.

After walking through this corridor, they entered a relatively spacious hall.

The hall was empty except for some machines operating there.

Lin Yifan and his team did not linger too long, continuing along the corridors of the arms organization's base.

There were signs along every corridor, which greatly facilitated Lin Yifan and his team.

They could follow these signs to find the command center of the military base and thus take control of the leader of the arms organization.

However, what they did not know was that danger was drawing near.

At this moment, nearly all personnel in the military base had donned gas masks and protective suits. They were waiting for the arrival of those four East Asian people, preparing for a most sneaky poisoning.

Turning left and right, following the signs, Lin Yifan and his team quickly arrived at the military base's command center.

However, as soon as they entered the command room, they were surrounded by mercenaries wearing protective suits and gas masks.

Seeing this situation, Lin Yifan immediately thought of the arms organization's malicious plan; the arms organization wanted to use biological weapons to kill the four of them.

"Everyone be careful, they are going to use biological weapons. Biological weapons are a type of bacterium and virus weapon that can directly damage human organs and tissues; make sure you do not breathe in these gases, and be sure not to let these gases corrode your skin," Lin Yifan warned and instructed.

Having witnessed the formidable power of biological weapons and experienced them in the military, he knew how dangerous they were; thus, one must not breathe in this virus-laden air.

"Understood." Having said that, Li Dafeng and the others immediately used their Cultivation Power to protect their bodies.

Cultivation Power could repel and defend against attacks, poison gases, and water, and it could also provide oxygen; so for a short time, biological weapons posed no threat to them; however, in the long run, they would definitely be killed by the biological weapons; because as they resisted the poison gas and provided oxygen, Cultivation Power would gradually be depleted. Once Cultivation Power was exhausted, they could no longer resist the virus-laden gases.

However, looking at the current situation, their Cultivation Power should be sufficient to eradicate these arms organization personnel. By then, after seizing the gas masks and protective suits from the arms organization personnel, they could conserve their Cultivation Power.

The next moment, the mercenaries from the arms organization started launching biological weapons in an attack.

They stored the poison gas in a glass bottle, and as soon as the glass shattered, the poison gas rapidly dispersed and blended into the air.

Lin Yifan and his team had been fully prepared; at this moment, they swiftly retaliated and charged to massacre the arms organization's mercenaries.

Seeing the enemy's fierce deployment, the people from the arms organization accelerated the launching of biological weapons, swiftly filling the command center with poison gas.

"Bang! Bang! Bang!"

One bottle after another shattered, releasing clouds of green poison gas; soon the entire command room was engulfed in the gas.

Yet, despite this, they still couldn't kill these four Asian people, as if they were divine beings from the heavens that didn't need to breathe the air of the human world.

The people from the arms organization were astounded, unable to believe that even their most potent biological weapons were ineffective against these four Asians who didn't wear gas masks or protective suits. This left them feeling incredulous and completely out of options.

Meanwhile, having stormed into the enemy's encirclement, Lin Yifan and his team unleashed a slaughter, killing one ruthless mercenary after another.

Instantly, the military base was filled with continuous shrieks; one mercenary after another was killed, their bodies poisoned by the virus, eventually decomposing into the grotesque form of zombies.

"Damn, is a biological weapon really this horrifying?" Li Xiaofeng was utterly shocked; it was his first encounter with the power of biological weapons. Now, he despised these inhumane arms organization personnel even more.

If these biological weapons were to spread to every country, it would surely result in catastrophic loss of life; therefore, they must eradicate this arms organization.

"Inhuman scum, they can't be allowed to live," Lin Yanping also detested them deeply. At that moment, she struck even harder.

"Die, you malicious scum!" Li Dafeng roared furiously, slashing vigorously with his sword.

"Boom!"

Suddenly, the mercenary before him collapsed, never to rise again.

As group after group of soldiers fell, the high-ranking officials of the arms organization who had been observing from the back grew frightened. If they allowed these four Asians to continue their attack, their own demise was inevitable; so they decided to change their plan.

Since biological weapons were useless against these four Asians, they decided to use the weapons these Asians feared—bombs, rocket grenades.

So, they immediately ordered a group of soldiers to arm themselves with hand grenades and rocket launchers to attack these four Asians.

Before long, the mercenaries on the front line heard the retreat order and immediately began to pull back. Then, a group of mercenaries armed with hand grenades advanced to the front line and pulled the pins, hurling the grenades towards Lin Yifan and his team.

Watching this scene, Lin Yifan and his team quickly batted the hand grenades back, killing the suicidal group of mercenaries.

The mercenaries throwing the grenades never anticipated that these four Asians would dare approach and strike the hand grenades back, and it was outrageous enough that they dared, but what was even more insane was that they managed to hit every single one, utterly dumbfounding them.
