As I walked into the cave, I could faintly hear the sound of dripping water.

The cave was very dark, but fortunately there was a bright flame jumping on Zhang Chuheng's hand, otherwise it would be pitch black inside and nothing could be seen. The flame illuminated the entire cave, allowing them to see the situation inside the cave clearly.

Above your head are upside-down stalactites, colorful. Water drops drip down the stalactites and onto the ground. There is a thin layer of ice on the ground, and the sound of ice and water hitting each other is like beautiful music.

The shapes of the stalactites are bizarre, yet remarkably harmonious, hanging upside down overhead.

This is just the first cave. There is a corner further ahead. At the corner stands a huge cliff, like a judge from the underworld. Gusts of cold wind come from the corner, which is creepy.

The two looked at each other and walked towards the corner cautiously. The gusts of cold wind became more and more fierce, making people stop and dare not move forward.

"Go in and take a look!"

Xiang Heng nodded and walked around the corner. Under the illumination of the flames, they could see the situation inside the cave clearly. It seemed that there were people living in the cave, otherwise why would there be a stone bed, a stone table, several stone benches, and even a few sets of stone bowls and chopsticks in the corner.

The area inside the cave is three times larger than that outside and can accommodate dozens of people. After turning the corner, the gloomy wind disappears and there is a warm feeling instead.

"It looks like someone once lived here. It seems like a good choice!"

"Um!"

Unlike outside, it doesn't seem humid here, and it's even a little dry. Xiang Heng thought a lot and thought that if they encountered any danger, this place could still be their shelter.

"Let's go, let them in first!"

Seeing the two people come out, the Thunder team breathed a sigh of relief.

"Is everything all right?"

"Well, don't worry, there's no danger in there. It's big enough to accommodate dozens of people. Just find some dry firewood, and there won't be any danger!"

"good!"

After finding enough firewood for tonight, everyone followed Xiang Heng into the cave.

When they saw the scene inside the cave, everyone was shocked. Their first reaction was the same as Xiang Heng's. Someone even wondered if this was where some hermit or sage lived, and they began to look for treasure in the cave with great interest.

"Le Yan, this is what you gave us this morning. Do you have any more? Do you want to eat some with us?"

Looking at the tent that Su Leyan took out, a hint of envy flashed in Jiang Mianmian's eyes. This envy happened to be seen by Zhang Chuheng, and he was even more dissatisfied with Su Leyan. However, he was not a fool. He would not act rashly before finding out Su Leyan's strength!

"Need not!"

Then, under Su Leyan's gaze, he walked calmly into his tent, not feeling embarrassed at all, or thinking of inviting Jiang Mianmian to sleep in the tent with him!

Jiang Mianmian tightened her grip on the bread. She knew that Su Leyan was not sociable and even a little cold and arrogant, but she didn't expect that even at the end of the world, she still hadn't changed at all. Was she really capable of fighting, or did she have someone to rely on?

"Mianmian, Miss Su will definitely have enough to eat. Come over and eat something first. I've made the bed for you. You can sleep on it tonight!"

There is only one bed in this cave. Su Leyan has his own tent. Mianmian is a girl and the main member of their Thunder Team. Of course, they can't let Mianmian sleep on the ground.

"Um!"

Jiang Mianmian did not refuse. They were comrades-in-arms. A month of getting along was enough for them to understand each other. Too many excuses would make them become strangers, which was unnecessary!

"Don't worry, when we come out later, we'll bring the tent with us too!"

Jiang Mianmian grinned, "Yeah!"

…

"Don't worry about us old guys. If you break through, you still have a chance to leave here. If you guard us old guys, you will die!"

"Captain Han, take your men and leave 9899. Communications are sporadic, and the situation outside is definitely worse than here. We old guys have lived long enough, and you're still young. You can't die here!"

Han Qingsong said with a stern face, "It is our responsibility to protect the 9899 Military Research Institute and you. No matter what happens, we will not abandon you!"

"But this is a special period. As you can see, if the Military Research Institute is in such a state, then the situation outside must be even more chaotic. We can't just sit there and wait for death!"

"You guys go from the back. Without us old guys holding you back, you'll definitely be able to break out!"

"it's useless!"

Looking at the dense swarm of zombies in the square, Han Qingsong couldn't help but feel a chill in his heart. No one expected that things would happen so suddenly. Overnight, the whole world changed. Now they not only have to face the threat of those zombies, but also the mutated plants and animals around them. They are already under attack from both sides.

If he led his men out, they would indeed be able to break out of the siege, but there would also be heavy casualties. They only had more than 200 people, while there were more than several thousand monsters. There were more than 4,000 people in the entire military research institute, and in the end only a few of them survived. You can imagine how high the mutation rate is!

"Professor Yang, don't worry. We will definitely be rescued. The Military Research Institute still has plenty of food reserves. Even if we stay here for a year or two, we will be able to survive!"

"Gao Jianwei, you take care of these professors. I'm going to be out for a while!"

"team leader!"

A trace of worry flashed in Gao Jianwei's eyes. He knew that the food reserves in the laboratory had been almost eaten up in the past month, and the military research institute's stored supplies were not in the laboratory. The captain must want to break through the heavy encirclement of zombies to get the supplies, but there are so many zombies outside, the captain is in great danger this time!

"It'll be fine!"

Fortunately, he had moved a lot of supplies in from outside intermittently before, otherwise he would not have been able to hold out for a month. But it was still too little. Now there are more than 200 people waiting to eat. Only when they are well fed and well watered can they fight against the monsters outside!

"careful!"

…

The next morning, after everyone had eaten and drunk their fill, they set out again to find the Military Research Institute. Today's journey seemed to be particularly smooth, and they did not encounter any attacks from mutated animals or plants, which was good news!

"Wait, I think I heard something!"

Ning Chuan suddenly frowned, and lay on the ground, listening carefully. Jiang Mianmian explained on the side, and Su Leyan nodded in understanding. The direction of Ning Chuan's evolution should be hearing. This ability is neither good nor bad!

"How about it?"

"We may have found the Military Research Institute!"

Ning Chuan's eyes flashed with a smile, and he said excitedly, "I just heard the roar of zombies. Because the distance is too far, I can't hear it clearly, but I can be sure that it is in this direction!"
