Zhang Heng looked at the blue spiral-shaped test-tube potion in his hand, and couldn't help but lose his mind slightly.

Although he had expected it, when this virus really appeared in front of him, the shock in his heart was still beyond his expectations!

This is a T-virus, just such a small tube of liquid, and it completely destroyed a civilization! Even the infamous nuclear bomb is as ridiculous as a child's play in front of it!

Before, Zhang Heng attracted the licker to leave the laboratory, and then came to find the goal of his trip at the fastest speed in his life, but when he saw three rows of identical T virus stock solution on the experimental table, his heart was still surging. He even found a bound book of test materials next to him, on which were only a few large words: Tyrant materials.

This is really nowhere to find the iron shoes, and it takes no effort to get it!

"Roar!"

Just when Zhang Heng was holding the T-virus test tube with a trembling hand, suddenly there was a violent roar from the bottom of the building! At the same time, there was a sound of glass and concrete breaking out of thin air, the sound came from far and near, Zhang Heng woke up from his emotion, it seemed that the creeper had found out that he had been tricked to divert the tiger from the mountain!

didn't care how the other party found out, Zhang Heng didn't say a word, pulled out three T-virus stock solutions with one hand, grabbed the information with the other, ran down the stairs quickly, ran to the fifty floors, and then hid in an office in the depths of the corridor!

"Julian, how much is the teleportation cooldown?" Zhang Heng said eagerly.

"There are still four minutes and thirteen seconds until the forty-eight hour cooldown, come on, just hold on for another four minutes, and you can complete the trial!" Julian's voice was so heartless at all times, and he didn't care at all about whether the host was alive or dead.

Four minutes!

Zhang Heng began to take a deep breath, because he remembered the information of the licker - judging from the movie and so on, the licker lost his vision, so his sense of hearing and smell was greatly strengthened, and his sense of smell was estimated to be weaker than that of the wolf dog, and his sense of hearing was far superior to that of the wolf dog!

The zombie blood on Zhang Heng's body has not dried up, and it can still hide his own taste, but the sound of his heartbeat can't escape the other party's ears no matter what!

Well, the only way to lower the sound of your heartbeat is to take a deep breath and forcibly suppress the intensity and speed of your heartbeat to hide your position!

In the great horror between life and death, Zhang Heng's desire to survive was completely transformed into the potential of life, as he took a big breath, his heartbeat quickly decreased at a speed that was difficult for ordinary people to match, and at the same time, the sound of heavy breathing gradually weakened, and finally it was undetectable!

At this moment, if there was an ordinary person by his side, then he would be surprised to find that Zhang Heng's sense of existence had miraculously decreased, if he didn't deliberately pay attention, then even if the other party stood in front of him, it would be difficult for him to pay attention to the other party!

"Roar!"

However, when Zhang Heng's heartbeat gradually dropped below that of a normal person, the roar full of anger from the licker had resounded on the roof of the building, and Zhang Heng knew that the other party had climbed up again! He looked at his watch, there were still three minutes left before the teleportation cooldown!

Come on!

Zhang Heng only felt that his whole body was slimy, because of the excessive secretion of adrenaline, Zhang Heng broke out in a cold sweat all over his body, and the blood that was almost dry was soaked again, emitting a strong stench!

However, Zhang Heng didn't care about these anymore, he just stared at the time in his hand, and didn't dare to imagine how long the other party would find him.

Rumble!

An office on the fifty-second floor was blasted open by a licker, and from the position, it should be the office where Zhang Heng threw the computer before and attracted the other party. It seems that although he is smeared with zombie blood, he is still a little worse than a licker who is more sensitive than a dog's nose......

There was a violent turning sound from the fifty-second floor, as if because the licker couldn't find Zhang Heng, he used those tables and chairs to vent his anger, but soon, the sound disappeared completely......

Did the other party give up?

Zhang Heng simply switched to breathing through his mouth, trying not to make a little noise, filling his lungs with air with every breath, and only exhaling it again after a short period of breathing.

Rumble!

However, before Zhang Heng could let out that breath, the door of an office on the fifty-first floor shattered. It seems that the Licker has searched the fifty-second floor, is it not ready to search the entire floor?

Thinking of this, Zhang Heng panicked in his heart, and his heartbeat became rapid again. He immediately adjusted his breathing. There are two minutes left, just two minutes! Please, it's only two minutes!

Zhang Heng looked down at his watch from time to time, he hated for the first time why time was moving so slowly, it felt like a long time had passed, but the watch had only gone a little!

Gradually, there was no sound on the fifty-first floor......

Rumble!

This time the silence lasted much longer than last time, but the sound of the wooden door breaking made Zhang Heng's whole body tremble, because that voice was only a wall away from his office!

Zhang Heng took a deep breath and no longer suppressed his heartbeat, and at the same time he stood up suddenly, ran to the window and opened the floor-to-ceiling window in front of him!

Twenty seconds to go!

At the moment when Zhang Heng opened the floor-to-ceiling window, a large wind poured in, and the higher he went, the stronger the wind speed, which was originally common sense, but at this time, there seemed to be something in the wind.

Be...... Raw cravings?

Zhang Heng originally had a slight fear of heights, but at this time, looking down from a height of nearly two hundred meters, he did not feel a little afraid, but turned his head frequently, looking at the fragile and vulnerable wooden door!

Twenty seconds...... Ten seconds, nine seconds, eight seconds!

At the moment when there were still eight seconds left, Zhang Heng saw the door bang and be smashed open by a huge force! A large amount of debris flew onto Zhang Heng's cheeks and body, but at this time, Zhang Heng didn't even blink his eyes, but he breathed a sigh of relief, and gestured a middle finger towards the ugly monster that poked his head into the door!

"You're late!"

As he spoke, he watched as the monster kept rushing towards him, and with a slight leap, he jumped out of the window like a bird!

Six seconds!

The moment Zhang Heng jumped out of the windowsill, he also looked at his watch, there were still six seconds left!

For a normal person, six seconds is just an insignificant moment in his life, a slight loss of consciousness, a brief daze, and six seconds pass quietly like flowing water.

Sometimes, however, six seconds is ...... A moment that is enough to decide life and death!

Enough is enough!

Zhang Heng fell rapidly towards the bottom of the building at the speed of free fall, with a height of nearly two hundred meters, anyone who saw it would think that this person was dead, but this common sense cognition did not include Zhang Heng at this time!

At the moment when it was only a millimeter away from the ground, Zhang Heng's rapidly falling figure flashed suddenly and disappeared completely!
