There are two roads leading to the second floor of the underground. One is an electric vertical elevator with a box-shaped pod as the carrier medium, and the other is an ordinary staircase. To complete the plan Su Hao mentioned, you can only walk the walking staircase.

But Bu Er turned on the backup power system, operated the computer, connected it to the host of the underground research institute, and continuously created new programs to take over the operating system here.

Su Hao looked at Buer friendly and said softly: "Thanks to you."

Buer typing on the keyboard with his hands frantically, his forehead was covered with sweat. When he heard this thank you, he couldn't help but raise his head and smiled slightly, and replied confidently: "The system program here is very complicated, but if you just want to focus on a little bit, control the channel system... Give me another 10 minutes and I can get them done!"

After hearing this, Su Hao nodded, and then said to Lantian in a suggestive tone: "It's better to turn on the lighting system."

Lan Tian frowned and said, "No, after turning on the light, aren't we exposed it?"

Su Hao smiled and shook his head, and replied: "The second underground floor is like a closed dark hell for the zombies hiding inside. They have become accustomed to living in the darkness. If they suddenly see light, they will be extremely uncomfortable, and then we will have the advantage of the territory."

Lan Tian pondered for a moment, nodded in agreement, and said, "It makes sense." Then he said, "Open the light."

Soon, the dim layer suddenly became brighter, and the environment was clearly presented to everyone. In fact, compared with zombies, their eyesight is excellent, and there is no big difference between day and night. For humans, it is better to see clearly during the day. Su Hao advocates turning on the lights, which is based on this consideration.

"It's done!" Buer rubbed his fingers excitedly, then knocked on Enter, "The stair door opens in 30 seconds!"

"Hurry, take your place!"

30 seconds passed quickly, and the stair door leading to the second floor underground finally slowly opened through remote control. The dazzling light shone the already dark area. At the moment of light being thrown into it, a series of painful howls came out, as if they were suffering great pain.

The sound gradually became louder from far to near, and finally, a tall male zombie in a tattered white coat came first. His eyes were dull and his face was filled with black corpse spots. This was obviously a feature of the zombie, but a ferocious parasite was spurted out from its mouth! The parasite that bloomed like four-petal chrysanthemum and closed looked extremely terrifying, and sharp fangs appeared on it. If it was bitten, it would be a dead end.

Looking at the characteristics, it should be that the body is zombie-like and is parasitic by parasitic beasts. Not only is the zombie-like physical fitness greatly enhanced, and there is no pain to make it the most terrifying combat machine. At the same time, the parasitic beast takes over the control of the body, and its thinking ability is slightly better. The parasitic beasts sprayed out of its mouth also have extremely strong attack power... This kind of zombie is the most terrifying existence.

And following the light, he finally walked here step by step, a layer underground.

Lan Tian stared at the parasitic zombie, his narrow and soft eyes flashed with a knife-like light. Although he saw this zombie, he used the watch on his wrist to continuously emit information codes to communicate with his teammates around him, because as an agile contractor, his hearing was undoubtedly very good, so he naturally knew that this enemy on the second floor of the underground was not the only one.

Su Hao's M4a1 bullet was loaded, but he was still waiting quietly because he knew that there were even more terrifying enemies that had not come out.

Next, some ordinary zombies and parasites came out, perhaps because they had been suppressed in the dark for too long. They looked extremely violent and restless. When they observed their bodies, they found that their muscles were deformed and developed. Although they were very fast, their movements were extremely stiff.

But after they came out one after another, no new enemies appeared.

“6…7.”

Lantian silently counted the number of enemies and finally confirmed that there were only 7 enemies, but these seven enemies were obviously stronger than ordinary zombie parasites, especially the parasitic zombie in the lead, which was even more powerful.

The dark underground second floor finally made no sound, and even the smallest sound did not appear at all. Lan Tian finally confirmed that the only enemy was the zombie parasites in front of him.

Su Hao and the other four were arranged in a four-sided array at this time, and they were hiding in four corners of the first floor. There were old machines in the corners that could block the view, so it was basically an ambush, which theoretically was foolproof.

What they are doing now is to wait, waiting for the enemy to be completely exposed to everyone's sight, and then they can use the advantage of guns to suppress the other party!

Buer's headphones finally received a very exciting and exciting sound wave signal. This signal was sent by the blue sky. Although he looked like a weak scholar and his main attack direction was electronic, his bones were also full of belligerent genes. This sound wave signal sounded as exciting as if he was injected with chicken blood. He couldn't wait to take out the AK100 behind him, and directly exposed his head and poured out a crazy bullet, directly pressing a zombie to the ground!

The first gunshot was like the death horn blown by a massacre. The others also hurriedly showed their heads, and Su Hao and the other man also took out their rifles and fired them!

The guy Lantian even used his crossbow to shoot silver arrows. The silver crossbow arrow seemed to have a strong killing effect on zombies and parasites. The bullet hit the enemy but could not see any actual effect. It only had physical impact and repelled. As long as the silver crossbow of Lantian shot the enemy, it would be a transparent hole!

So in all, only five silver arrows in the blue sky caused real substantial damage to the enemy, and even if the zombies and parasites were beaten with holes, they could not kill their vitality at all!

"Does it depend on him? These scumbags are really hard to fuck. How could they not be killed by life or death?" Another strong man who looked tall and strong, tilted his firepower frantically, but under Gatlin's anger, the enemies could withstand it. The vitality was strong and the ability to resist the attack was imaginable.

Su Hao found that his firearm output was not powerful, so he took out another grenade (this grenade was asked for at Lantian), bit off the safety bolt, and threw it directly at it!

"boom!"

A lotus of death bloomed on the ground. The grenade was so powerful that it exploded the surrounding instruments and equipment, not to mention those zombie parasites with flesh and blood, they were even more blown up and lost their bodies as a medium of action, so it was not a threat at all!

However, the remaining parasitic zombie was far away from the center of the explosion and was very strong, so he did not suffer any harm in this explosion. After lying down, he stood up and headed straight for Su Hao!

When Su Hao saw this, he quickly leaned over. The only remaining zombie squirted out of the ferocious parasitic beast, and four flesh teeth bloomed. It seemed that he wanted to wrap around and swallow Su Hao!

Su Hao looked at the parasitic zombie that was rapidly amplified in front of him. Even he was shocked at the speed and quickly activated the demonic aura. Although the demonic aura at this time had no effect on dead creatures like zombies that only rely on instinct, Su Hao saw that the parasitic beast was the one who controlled the body at this time, so it was also said that the demonic aura was concentrated in the ferocious four-petal flesh flower that spurted out from his mouth!

Sure enough, after being disturbed by Su Hao's demonic aura, his movement speed did drop a little, so the pounce was actually avoided by Su Hao and hit the wall!

I still can’t write it out, so I’ll break my promise, but don’t collect it!! I’ll see if I can make it up tomorrow!
