At this time, Su Yuan also expressed his position and said: "I also agree with Xiao Ling. Go explore the tunnel and maybe you will find something!"

"Oh yeah! Big brother, your thoughts are exactly the same as mine!"

Lan Qingling shouted excitedly, this little girl is quite adventurous.

"Okay! But for the sake of safety, we'd better prepare first. I just discovered that there are several undamaged rooms in the Underground Biological Research Institute. Let's go to those rooms first and see if we can find some.

Bring the appropriate equipment, and then go into the tunnel to explore!"

Seeing that Su Yuan and Lan Qingling both agreed, Yu Baiying no longer objected, but put forward her own suggestions.

"Then just do what Sister Bai Ying said!"

Lan Qingling nodded immediately.

So the three of them returned to the Underground Biological Research Institute, entered the rooms that had not been damaged, and started searching.

After a while, they found several portable flashlights and several military backpacks in one of the rooms. After inspection, they found that these items were well preserved and could still be used even if they had been stored for decades.

So the three of them each brought a military backpack and a portable flashlight.

Then they found a large iron shelf in another room with a large iron box on it. When they opened it, they found dozens of buttered firearms and hundreds of ammunition boxes inside.

Inside is a magazine full of yellow bullets!

Yu Baiying came closer to identify it: "This is the Type II submachine gun! This gun was designed and produced by the Japanese military during World War II for fighting in the Pacific War. It was mainly distributed to the Japanese Marine Corps fighting in the Pacific. Because the cost was quite high,

Therefore, there are not many of them, but I heard that this gun is quite powerful!"

While talking, Yu Baiying picked up a Type II submachine gun and skillfully pulled the bolt, finding that it was quite smooth.

So Yu Baiying picked up another magazine and loaded it into the Type II submachine gun, raised the gun and fired at the door.

Da da da…

Amidst a series of dense, clear and loud gunfire, the door of the room was suddenly swept into a honeycomb shape by bullets!

"This batch of firearms is well preserved and very powerful!"

Yu Baiying nodded and said, "I suggest that each of us bring one for self-defense!"

Hearing what Yu Baiying said, Su Yuan also stepped forward and picked up a Type II submachine gun, followed her example, and loaded a magazine of bullets.

In fact, with Su Yuan's strength, he didn't need to use firearms, but he thought of the rules of Yun Zhongzi and the Sword Immortal Sect, so he chose to keep a low profile. Moreover, he had never played with a gun before, and he wanted to take this opportunity to give it a try.

.

Lan Qingling just glanced at the Type II submachine gun and said with disgust: "What's so good about this crappy gun? I don't care about it!"

It's no wonder that Lan Qingling said this. After all, the department where this little girl works is the technical department of the LHD super elite force, which specializes in the research and development of various advanced equipment. Naturally, she looks down upon this kind of World War II-era weapon.

Yu Baiying was stunned for a moment, and then said to Lan Qingling: "Xiao Ling, I know you don't like this kind of gun, but these are extraordinary times, so you can make do with it!"

"Anyway, I don't like this kind of gun. I'd better look for it myself and see if there is any equipment suitable for me!"

Lan Qingling still didn't take the Type II submachine gun, but continued to search the room.

After a while, Lan Qingling found several large sealed wooden boxes in the corner of the room. She looked at the Japanese writing outside the boxes, and then excitedly said to Su Yuan: "Brother, please come and help me."

Let’s open these boxes!”

Su Yuan hurriedly walked over and asked Lan Qingling: "Xiao Ling, have you discovered anything good again?"

"Here, the good things are in these boxes. Just open them for me!"

Lan Qingling pointed to the large wooden boxes and said.

Su Yuan didn't ask any more questions, directly raised his hand and struck it with several palms.

Bang! Bang! Bang!

The sealing lids of those large wooden boxes were suddenly cracked open by Su Yuan.

Inside were piles of things that looked like square bricks sealed in yellow paper, as well as detonators and fuses.

"These are TNT explosives. I can modify them and use them!"

As Lan Qingling said this, he took out the square explosives, rummaged through some wires, and even disassembled dozens of Type II submachine guns, took out the gun springs inside... and then took them to a table outside.

, and started to tinker.

After struggling for about an hour and a half, Lan Qingling made dozens of things that were about the size of cans.

Su Yuan had been watching Lan Qingling curiously from the side. After seeing her finish, he couldn't help but ask: "Xiao Ling, what are these things you made?"

"Oh, these are the mini bouncing bombs I made. With these things, we can basically walk sideways on this island!"

Lan Qingling said this in a rather proud tone.

"Uh...is this mini bouncing bomb...very powerful?"

Hearing such a name that was full of the aura of a middle school student, Su Yuan couldn't help but feel a little suspicious.

"Brother, don't question my professionalism!"

Lan Qingling smiled, then she put the dozens of "mini bouncing bombs" into her military backpack and waved her hand: "Ready, we can set off..."

After saying that, Lan Qingling kicked open the door and walked out first, looking furious.

Su Yuan and Yu Baiying looked at each other for a moment, then picked up a dozen bullet magazines, stuffed them into their respective military backpacks, and left the room.

After a while, the three of them came to the entrance of the tunnel again, bypassed the corpses of more than a dozen giant rats, turned on their portable flashlights, and walked deeper into the tunnel...

This tunnel is very deep, cylindrical in shape, and is surrounded by thick cement walls. It becomes wider as you go deeper, and the air does not seem dull in such a deep underground. It turns out that in this tunnel

There are many ventilation and exhaust openings at the top, which should lead directly to the ground.

The more the three of them walked inside, the more they discovered that the engineering and scale of this tunnel was far greater than the military base on the surface!

As I continued walking forward, I suddenly heard a strange squeaking sound and black shadows.

The portable flashlights of the three people shone in the direction of the sound, and red eyes flashed in the darkness. They turned out to be a large group of giant rats, gathering in groups outside a large iron gate.

There was a strange sign printed on the big iron door.

When the light beam of the portable flashlight shone through, the group of giant rats were immediately alerted, and they rushed towards the three of them!

Seeing this, Yu Baiying picked up her submachine gun without hesitation and started shooting at those giant rats.
Chapter completed!
