When he heard Qin Mo's words, Shi Qing suppressed the fear in his heart and raised his head to look at the last sealed container. He carefully identified it and finally found a trace of familiarity from the bloody face.

Was this really the experimental subject that had escaped just now?

Why didn't he stay away from the glass bottle? Why did he run into the glass bottle by himself?

Did he want to pretend to be a corpse and get away with it?

Did he have to be so naive, monster?

'Wait a minute …' Shi Qing suddenly realized that something was amiss. This experimental subject was missing a leg, but why did it grow back now?

Could it be that this place could allow the experimental subject to quickly repair its body?

Was that why this monster was hiding in here?

Just as he was feeling shocked, the glass bottle shattered completely with a bang. It instantly disintegrated like a sand castle. The glass shards that burst out were like stars in the sky, beautiful but dangerous.

Qin Mo and Li Su both retreated quickly. They avoided large pieces of glass shards but were inevitably injured by the shards, causing some blood to flow.

Shi Qing knew that things were not good. Although these glass shards were hard, they didn't cause much damage to humans. However, they were enough to cause a small disturbance and create an opportunity for the experimental subject to escape.

He thought of it, and Qin Mo wouldn't be careless. He quickly raised his hand and fired a shot at the fast-moving figure without hesitation.

The bullet pierced through the flying glass shards, tore through the air, and shot directly at the experimental subject that was trying to escape.

The experimental subject's speed was indeed exaggerated. He actually jumped up in such a one-thousandth of a second and avoided a fatal injury. Only the bullet shot into his calf.

Perhaps for humans, a calf injury would greatly reduce their mobility, but the experimental subject didn't have such concerns. His speed didn't decrease at all, as if he wasn't injured at all.

Qin Mo saw it clearly, but he wasn't anxious at all. As he fired another shot, the corners of his mouth slowly curled up.

He didn't buy many bullets in the system space, but he spent a lot of money to buy a few explosive bullets. As long as they were shot into the body, they would cause an internal explosion.

It didn't matter if he didn't feel pain, but if the lower half of his body exploded, where could he run to?

Bang …

The flames of the explosion burned, mixed with the smell of blood and gunpowder. It was extra pungent, and at the same time, the scene was very unbearable.

At least, Shi Qing, who was timid and afraid of being disgusted, had looked away early. But when he looked away, he unexpectedly caught a glimpse of Leng Lin who had jumped down from the entrance of the cave.

Leng Lin stared fixedly at the experimental subject that had fallen limp on the ground. Perhaps he thought that no one was looking at him, but a strong anger burst out from his eyes, almost burning the black in his eyes into a blazing red.

He clenched his fists tightly, as if he was suppressing his emotions. The next moment, he calmed down and became serious and reserved as usual.

His expression changed so quickly that it was almost gone in a flash. It made Shi Qing, who had been watching, feel as if his eyes were playing tricks on him.

At this moment, Leng Lin spoke, "That's great. You guys are indeed very outstanding!"

Li Su immediately turned to look at him.

Qin Mo glanced at him before walking towards the collapsed Experimental.

This time, he did not destroy it humanely. Instead, he carefully examined it, as if he had discovered something interesting. He was very engrossed in it.

Shi Qing was thinking about what he had just seen. He couldn't figure it out. It was impossible for it to be an illusion. What did Leng Lin mean by that?

Why was he so angry?

And why was he trying so hard to hide it?

It was a pity that there were outsiders present now, so he couldn't talk to Qin Mo. However, he still placed all his attention on Leng Lin, wanting to observe him for a while longer.

Leng Lin frowned as he observed the experimental subject. He put on anti-bacterial gloves and started to collect the serum.

Qin Mo stood beside him. "Do you need help?"

"No need."

Qin Mo didn't leave even though he was rejected.

There was a special device for collecting the serum. After the preliminary preparations were completed, they could wait quietly.

Leng Lin kept looking at the experimental subject. There wasn't much expression on his serious face.

Qin Mo looked at him and suddenly asked, "Will he die after the serum is extracted?"

Leng Lin stared at the experimental subject. After a while, he replied, "Yes." After that, he became silent, as if he was in a daze.

Qin Mo sized him up. Then, he asked casually, "There are only two experimental subjects here?"

"Yes."

Leng Lin replied casually. But the next moment, he was suddenly stunned. He quickly glanced at Qin Mo, but he met Qin Mo's gaze.

Qin Mo stared straight at him. His pair of dark eyes were unfathomable. There seemed to be a temporarily silent ferocious beast hiding in them, waiting for the prey to reveal itself so that it could pounce and kill.

Leng Lin's temperament was strong. He forced himself to look away and said calmly, "That's what the detector shows."

Qin Mo didn't continue to ask. Instead, he changed the question. "Can this serum be refined into antibodies?"

Leng Lin paid attention to the collection of the serum and replied, "There's an eighty percent chance."

"Then … is it infectious?"

Leng Lin's body suddenly stiffened. He turned his head extremely slowly and looked at Qin Mo expressionlessly.

Qin Mo was also staring at him. Then, he opened his mouth slowly and asked almost word by word, "Is it?"

The air seemed to have frozen. The two of them looked at each other, their gazes glued together.

Li Su noticed the undercurrent between them. He looked at them with confusion. He could feel the hostility the mercenary had towards Leng Lin, but he didn't understand why.

At this moment, there was a sudden beeping sound. It turned out that the collection device had finished its work and successfully collected the serum.

A trace of joy flashed past Leng Lin's eyes. He ignored Qin Mo and hurriedly finished the final finishing work.

Qin Mo suddenly raised the gun in his hand and aimed it accurately at Leng Lin's heart.

Leng Lin was forced to stop. He stared at Qin Mo without fear. "What do you want?"

Li Su was also stunned. Just as he was about to take action, Qin Mo lifted the corners of his mouth and smiled evilly. Then, he changed his direction.

The gun was aimed at the unconscious experimental body on the ground. He quickly added a few more shots to the vital parts, completely killing the experimental body.

The second experimental body died.

The notification of the side mission rang in his ears. Shi Qing didn't care at all. He continued to stare at Leng Lin, trying to see other emotions on his face.

But this time, there was no flaw in Leng Lin's expression. He didn't have any reaction to Qin Mo's actions. He was very calm.

But in Shi Qing's eyes, this calmness was a little too much.

Leng Lin collected the serum silently. At this moment, the other two soldiers and two mercenaries rushed over. When they saw that the mission was completed, they couldn't help but heave a huge sigh of relief.

The mission was completed. They could finally go back.

At this moment, Shi Qing finally stopped observing Leng Lin. He suddenly became anxious.

Although the main mission was to escort the serum back to the camp, their side mission hadn't been completely completed.

There was only one experimental body left out of the three.

If they left now, they could only give up on the side mission.

But if they didn't leave and didn't personally send the serum back to the camp, would they be judged to have failed the mission?

If they failed the main mission, it would be useless even if they completed the side mission. Not only would they not receive any rewards, but they would also be deducted some coins.

As a newly appointed system master, Shi Qing was very clear about these rules.

Could it be that they had to give up the side mission to complete the main mission?

Please, they had already completed two-thirds of the mission. How could the two thousand five hundred coins that were already in their mouths fly away?

Unexpectedly, Leng Lin, who Shi Qing had always disliked, actually helped him.

He stood with his hands behind his back. His expression was calm. "Colonel Li, Mr. Qin, although we have successfully collected the serum, it is rare for us to come to this experimental base. Why don't we search for some data and bring it back to the camp to facilitate the research team's work?"

Li Su frowned. His mission was to bring the serum back safely. Now that the collection was completed, in order to avoid any accidents, they should immediately and safely retreat. They really shouldn't continue to stay here.

Especially … He looked up at Qin Mo and Leng Lin. His sharp senses reminded him that there was definitely something going on, and it definitely wasn't a good thing.

Thus, he said decisively, "Doctor, although there is no danger here for the time being, no one can guarantee safety. If we are surrounded by zombies again, our resources and manpower won't be enough to fight back."

Leng Lin looked at Qin Mo.

Qin Mo said, "Colonel, why don't you leave first. Leave the doctor to me."

This sentence was like a slap to Li Su's face. He immediately became angry. He was a soldier and was fearless. In this situation, how could he escape?

Leave the doctor to him?

What a joke. Who was the one who put the gun on Leng Lin's chest just now?

Leave it to him?

Then the doctor would really f * cking die here.

Although an impulse rushed to his head, Li Su still maintained his rationality. Even if he thought that leaving immediately was the best choice, he couldn't be reckless in the face of Leng Lin's persistence and Qin Mo's provocation.

Instead of arguing and wasting time, it was better to act immediately, find useful data, and take it away immediately.

After weighing the pros and cons, he finally nodded in agreement.

The experimental base wasn't big. It was about twenty meters long and ten meters wide. In this kind of space, the seven of them moved and found things very quickly.

When Shi Qing saw this situation, he knew that it was an opportunity. He gave Qin Mo a hint and Qin Mo left the crowd slightly.

Once he left, Shi Qing hurriedly told Qin Mo about his discovery just now in a low voice. He told Qin Mo about Leng Lin's abnormality and the emotions he inadvertently revealed when no one was paying attention.

The moment he finished speaking, Qin Mo touched him gently and said softly, "You did very well."

This generous praise stunned Shi Qing. In the end, he felt a little embarrassed and a little proud.

Shi Qing faked a cough and hurriedly suppressed it. He continued, "Leng Lin is strange. Do you think it might be related to the experimental subjects?

I think he might be familiar with the experimental subjects. Think about it, when he was doing the research, he might have known the experimental subjects … Eh, do you think Leng Lin might know where the third experimental subject is? "

Shi Qing's thoughts wandered as he spoke. He was almost convinced by his high IQ!

What a strong inference, what a reliable guess!

When he saw that Qin Mo didn't refute, he continued to spread out, "Leng Lin was a scientist who participated in the research back then. He must know a lot of things. And these experimental subjects that survived are the first batch. They are strong and have a strong influence on the zombies. From the contact during this period of time, they seem to have a certain level of intelligence!

And this place is an experimental base. This means that there are people in this group of experimental subjects who can conduct research. They might even be extraordinary scientists … "

Wait … Shi Qing was suddenly shocked by his own thoughts.
