A few minutes later, Zhang Yun, who had succeeded, appeared at another emergency exit of the underground biological and chemical weapons arsenal.

This entrance is rarely used even by the Japanese, and it is even more dangerous step by step, but it is not just as simple as a few guns guarding inside, there are several checkpoints, and even explosives are buried......

The most important thing is that when the old devil explained this emergency channel, he had come to the last moment of his life, and there was a thick look of irony in his eyes. Thinking about it now, Zhang Yun can't help but feel chills in his heart!

I don't know why I suddenly recalled these fragments in my mind, especially when I saw this door, even more so!

Taking a deep breath, he shook off the distracting thoughts in his mind, and Zhang Yun, who didn't want to go out through the front gate and fight with a large number of military police, finally took out the C4 ......

"Boom!"

After a loud bang, a light passage appeared in front of me.

Just as he was about to leave, Zhang Yun hesitated for a moment. After thinking about it, he turned back and grabbed dozens of Japanese corpses, put them in the space, and then returned again.

In order to prevent being plotted, Zhang Yun even straddled the signal jammer on his waist......

Although Zhang Yun also knew that the military police outside could not enter from the main entrance, they would definitely remember the emergency passage.

But if you can delay the time of exposure as much as possible, it can also give your life an extra insurance!

Not long after, he encountered the second of the six gates of the emergency passage. This time, Zhang Yun was familiar with the road and quickly carried out the blasting again.

Before the smoke dissipated, a large wave of poisonous gas was spit out on both sides of the passage, seeing this, Zhang Yun hurriedly retreated quickly, and hurriedly began to put on protective clothing......

It's just that before Zhang Yun was busy, the roar of a heavy machine gun sounded on the other side of the passage.

Although he had been prepared for a long time, Zhang Yun still won the bid, after all, the bullet is not a bow and arrow, and it can be avoided......

Retreat to the lobby at the beginning, tear off the protective suit, and look at the small hole in the three-layer body armor. As well as the bullets left in the body, Zhang Yun wanted to cry at this moment!

There is no doubt that no matter how strong the physical fitness is. But in the face of heavy machine gun attacks, he was only hit by one bullet, and he was seriously injured immediately. Although so far it has not lost its combat effectiveness. But the rest of the journey may not be so smooth......

For the first time, Zhang Yun felt a trace of remorse for his reckless actions. But it is clear that regret at this moment is useless.

So Zhang Yun immediately put away these emotions that he shouldn't have, and his heart was ruthless. I took out a large number of C4 from the space......

"I wonder if there are still people on duty in these passages?" Despite this doubt in my mind. But Zhang Yun didn't stop.

After a little bandaging, he dragged half of his lungs and severely injured his body. Continue the unfinished journey!

"Yamamoto-kun, there is still no news from the base, and he may still be fighting with the bandit who attacked the base......"

Before the subordinates could finish reporting, Yamamoto slapped him. "Yaga, are your brains full of mush?"

Yamamoto, who was still unrelieved after scolding, continued: "There are hundreds of armed forces on the base alone, plus more than 1,000 researchers, so many of their own people are there, if they are still alive, they must have already spread the news!" ”

"So, now we haven't received any news from the base, the only explanation is that the base has been captured, and everyone has been shattered, so let's take care of this only emergency channel, just now the bandits wanted to break through from us, but we beat them back......"

Just when Yamamoto was still talking, the soldier in charge of watching the monitoring rushed in and said: "The monitoring of the No. 2 section has completely turned into a snowflake......

"Oops!"

Before the soldier finished his report, the impatient Yamamoto thought he was blocking the way, so he flew him to the corner of the wall with a kick, and hurriedly ran to the monitoring room.

After a while, Yamamoto saw the scene of all the surveillance on the No. 2 section turning into a snowflake.

This scene not only did not make him feel angry and panicked, but on the contrary, a glimmer of hope rose in his heart.

You must know that all the monitoring of the No. 2 road section just now has also become the current scene, and then the gas switch controlled by the system is automatically turned on. Immediately after that, his minions fired......

So now there is this scene again, and the only explanation is that the bandits are once again wearing signal jammers and starting to approach section 2.

These thoughts flashed through his heart like lightning, and Yamamoto immediately jumped up and immediately picked up the internal phone......

Zhang Yun on the other side didn't know that when he approached the vicinity of Gate 2 again with a signal jammer, he would make Yamamoto Nakasa, the supreme commander guarding this safe passage, suddenly see through his intentions.

Therefore, at this moment, Zhang Yun continued his actions step by step.

The first was that a corpse appeared in his hand inexplicably, and then the corpse was thrown out with all his might. At the same time, at the moment when the corpse shot, Zhang Yun immediately turned around and ran!

Sure enough, before the corpses hit the ground, the roar of heavy machine guns rang out on the other side of the passage.

Fortunately, this time I was prepared, and finally ran back for Zhang Yun again......

"Now that it has been proved that the weapons in the passage are indeed controlled by someone, then it is simple, the gas bomb can't help you, can't the bomb either?" Zhang Yun, who was taking a breath, muttered to himself.

As soon as his mind moved, two pieces of C4 appeared in his hand so suddenly. Hurried back to where he had been standing.

This time, Zhang Yun didn't play any tricks or throw any corpses, but directly threw out the C4 in his hand.

Almost instantly, the passage was blown up, and only a glimmer of light came from the other side. It depends on the situation, even if one wants to pass. You should also take the sapper's shovel and work for half a day.

The thought turned to this, and a sapper shovel immediately appeared in Zhang Yun's hand, and when he was about to go to work, the Japanese soldiers who were bombed on the opposite side finally remembered to shoot.

"Bang ......"

It's a pity that the originally deafening roar of the heavy machine gun is no longer so harsh at the moment separated by a large pile of dirt!

Lying on the ground, looking at a few stray bullets that stubbornly passed through the mound, Zhang Yun had a whim, and immediately lifted the sapper shovel in his hand upward, and with a bang, took down the sapper shovel again. Zhang Yun was pleased to find that although the sapper shovel was deformed, it did not penetrate it.

"Hey...... It seems that these boys did not use special types of ammunition such as armor-piercing bullets. Looking at the three-layer body armor on his body, at this moment, the light of hope for a successful escape rose again in Zhang Yun's eyes!

After waiting silently for a while, sure enough, the heavy machine gun stopped temporarily, and when he saw this Zhang Yun, he jumped up and hurriedly ran to the mound. Start digging up.
