The exit of the elevator on the ground, under the fierce and rapid attack of the throwing knife, was pierced through more than a dozen holes, which were connected to form a circle.

Tremble in the balance!

Shen Yan burst out with all his strength and smashed into the middle of the circle, and in the boom, the connection between the holes was broken, and the middle piece was directly smashed away. And Shen Yan's body also thrust forward violently at this moment, and rushed out of the elevator door with the hole smashed by his fist.

"Boom!" The elevator roared up from behind, and Shen Yan rushed out dangerously.

The pungent smell of blood came to his face, and the terrible screams were endless, Shen Yan didn't have time to stay at all, and hurriedly ran to the nearest voice.

Sure enough, just like Tang Haotian said, the six living dead who were killed by him before have been "resurrected" at this moment, and even after being resurrected, their strength has improved compared to before.

A living dead man found Shen Yan and rushed towards him as soon as possible, this time Shen Yan did not repeat the mistakes of the past, the three flying knives rushed straight at each other under the control of spiritual telekinesis, and with a few snorts, the living dead was cut into pieces by his flying knife, and the dead could not die again.

"You're going to resurrect me again this time?" In his mind, Shen Yan had already rushed towards the second living dead.

Six fourth-level strengthened living dead, even if their strength reached the peak state, it would be a piece of cake for Shen Yan, and they were even more vulnerable under the attack of spiritual power. In the blink of an eye, he was eliminated by Shen Yan one by one, and soon he found Tang Haotian lying on the ground dying.

Tang Haotian's injuries were relatively not serious, but a hole was broken in his abdomen. On the contrary, around him, the corpses of many soldiers were scattered all over the place, apparently to protect him.

Shen Yan, who received the communication, returned extremely quickly, and he didn't even use a minute before and after, but even so, among the twenty-one people, including Tang Haotian, only nine people survived, and all of them were seriously injured and dying, and they could die at any time, and the only thing that could save them at this moment was Shen Yan's blood.

Without the slightest hesitation, Shen Yan immediately set out to save people, as for whether these people would become a member of the wolf pack after they were rescued, it was not something he could control now.

The creatures that were chasing Shen Yan underground before did not catch up with the ground, and even the elevator returned after not hitting Shen Yan, and even stopped at the exit of the elevator on the ground, as if waiting for Shen Yan to enter again.

As Shen Yan's level increased, the effect of his blood became stronger and stronger. Tang Haotian and the other nine people woke up in only half an hour after injecting his blood, and some of the relatively minor injuries were even able to get up and move.

"Thank you, Shen Yan, for saving the lives of all of us!" Tang Haotian said directly after waking up.

Shen Yan shook his head and said, "It's still a little late to return, twelve brothers are dead!" ”

"Don't say that, if it weren't for you, I'm afraid we would have casualties after we left Yangyuan Town." Even if he was injured, Tang Haotian was still the kind of person who saved time and sized, and after a little emotion, he immediately asked, "How is it, what is the situation underground?" ”

"It's not good, there are creatures down there, it should be mutant beasts and these living dead! And the underground control system has been controlled by them, which is not optimistic! As he spoke, Shen Yan looked around at the injured people around him. At this time, Tang Haotian understood for the first time that the not very optimistic in his mouth did not refer to the threats underground, but to the wounded people.

"If it doesn't work, let's go back to the building where we were stationed before, that building has a high floor, if we disconnect the stairs below and seal a few entrances and exits, the mutant beasts and zombies should not be able to go up to the room where we rest, and you ...... then."

Both of them were smart people and quickly understood what they meant.

Shen Yan was not polite, and after waiting for another half an hour, when everyone was almost able to barely move, they left the ground building of the scientific research institute and returned to the place where they were stationed before.

With Shen Yan's protection, the return to the garrison was very smooth, and after helping Tang Haotian and them establish a defense, Shen Yan returned to the scientific research institute again. This time, without Tang Haotian and their involvement, Shen Yan decided to go all out and directly crack all the secrets of this scientific research institute.

Because the elevator exit was broken by Shen Yan, it had lost its function of retraction, but it did not prevent it from entering the elevator. Shen Yan didn't think much about it, and after coming to the elevator entrance, he directly entered it and pressed the button to descend. The creatures of the underground scientific research institute seemed to be waiting for Shen Yan to enter, and the elevator went all the way down without the slightest change, and finally stopped in the hall again.

At this moment, the power was restored, and the entire hall and several corridors connected to it were once again displayed in front of Shen Yan's eyes.

"Damn, these guys are gone again, aren't they all ghosts?" Shen Yan muttered helplessly.

But as soon as his muttering stopped, the originally bright hall and the four corridors suddenly went dark, and the power supply was cut off again. Shen Yan, who had learned from the past, hurriedly closed his eyes in order to adapt his eyes to the darkness, and only opened them again after a while.

In the darkness, a vague shadow flickered, its movement speed was extremely fast, it was Shen Yan, who had an eighth-level strengthening strength, and at the moment he just opened his eyes, he almost couldn't catch the other party's movement trajectory.

The underground research institute is not an open space, coupled with the relationship between building materials, so that the detection effect of bioradar has been restricted to a certain extent, the original diameter of 500 meters of detection range, now can only reach half, and after encountering the wall barrier, the situation on the other side of the wall can only be vaguely detected.

Shen Yan pulled out the dragon teeth from the thighs on both sides, and with a flick of his body forward, he rushed towards the shadow that had been locked by the bioradar. In order to prepare for emergencies, the three throwing knives did not rush forward, but kept a fixed swim around his body to protect him.

"Click!"

The sound of metal cutting flesh and bones breaking sounded in an instant, and in less than two seconds, the shadow locked by the bioradar fell to the ground. Shen Yan looked intently, and saw that it was actually a person, a person covered in scale armor like a lizard.

"Is this a human?" Shen Yan was a little surprised.

"It's a mutant!" In her head, Mira's voice explained, "It's a combination of genes that causes the existence of mutations. Master, the creatures hiding here are not simple, you have to be careful! ”

From Mira's appearance to now, Shen Yan has never heard it, and the other party's words reminding him to be careful can also conclude that the creatures here are really not simple, which has attracted Mira's attention.

After the mutant was eliminated by Shen Yan, the darkness fell silent again, and Shen Yan set his eyes on a corridor, which led to the control center of the entire underground scientific research institute, "It can control the power system, and its location should be on the control center." ”

In his mind, Shen Yan had already determined the next action goal. Regardless of whether the other party is in the control center or not, as long as he can get there and control there, he can control the entire underground research base. When the time comes, it will be much easier to deal with that unknown creature.

Along the way, he suffered several waves of attacks, to be precise, he was harassed, and these people who harassed Shen Yan were all similar to the previous mutants. Aside from their appearance, they have very few other human features, and even a thick tail grows from the back of their buttocks.

Shen Yan didn't say a word, he advanced all the way, but all the obstacles that blocked his progress were cleared by him one by one.

Subconsciously concentrate on precautions, because the bioradar is affected by the wall, it can only detect the corridor under your feet, but the rooms on both sides of the corridor are very vague under the detection.

Suddenly, Shen Yan felt that his legs had become heavy, as if he had fallen into a swamp, and his whole body felt like he was soreness and weakness after strenuous physical activity. Even his very high spiritual power weakened at this moment.

According to the map of the scientific research institute given by Tang Haotian, Shen Yan is already very close to the main control room at this moment, and after passing through the last gate more than ten meters in front of him, and after going about 100 meters, he can reach the location of the master control computer.

In front of the gate, a T-shaped fork appeared in front of Shen Yan, the front room was the gate, and on both sides were two wide corridors. Shen Yan knew that the one on the left side of these two corridors was the passage to the miniature nuclear reactor; The one on the right is the passage to the small ecosystem of the underground research institute.

The gate was open, and when he approached the gate, Shen Yan was surprised to find that the door frame of the gate was completely covered by an unknown red goo, including the ceiling and the ground. The sticky substance hung down from the ceiling like snot, but it didn't break, and you could feel a slippery piece when you stepped on it.

Shen Yan didn't directly enter the inside of the gate, he had a very strange idea at the moment, the gate in front of him was like a mouth, if he walked in, it would be equivalent to walking into the mouth of the unknown creature. I'm afraid that the reason why the unknown creature was just harassing all the way, and didn't release a large number of creatures to attack itself like the first time he entered here before, was to let himself fall into the net like this.

"Mira, can you tell what this goo is?" During the stay, Shen Yan asked Mira Dao.

"The test has begun, the master ......," Mira responded, and quickly continued: "After the test, these sticky substances are organic matter, and the basic components are protein, sugar, and water...... and some trace elements, whose genetic agreement with humans is more than 93 percent......"

"What did you say?" Shen Yan's cheeks twitched, and he exclaimed in disbelief.
