23 The Source of the Virus, the Zombie Rats!

A huge jar filled with a faint red liquid was filled with zombies of various shapes.

Jumping zombies, crawling zombies…

Wang Chen had seen all of them before. Other than that, there were also a few breeds that he had never seen before.

Obviously, this virus laboratory was studying zombies.

Now, the evidence was irrefutable. The catastrophe outside came from the White Birch Virus Laboratory.

Soon, Wang Chen found a document that had fallen to the ground.

He picked it up and saw that it was a diary.

Wang Chen immediately began to carefully study it.

[March 8, 3012. The first experiment failed. We underestimated the virus's growth rate. The test subjects couldn't withstand it at all.]

[March 9, 3012. The second experiment failed again, but the test subject survived for 10 minutes after being infected with the virus. This is of great significance.]

[April 15, 3012. The third experiment made great progress. We obtained the first living experimental subject. However, he had low intelligence and was like a living corpse.]

[May 7, 3012. Experiment 4. The experiment has reached a bottleneck. We have obtained another form of monster, but it still does not have intelligence.]

[...]

[September 14, 3012. Experiment 17 had the same terrible result. The test subjects were still bloodthirsty monsters. The project might have to stop!]

[December 5, 3012. Experiment 18 was an even stronger monster. We still haven't gotten what the company wants. Dr. Dawson is going crazy.]

[January 7, 3013. The last experiment. We have failed! The crazy monster swallowed the extraterrestrial meteorite that carried the virus and completely lost control. Many people died. Poor Alice. God bless her.]

[...]

[March 17, 3013. We've received orders to terminate the project and immediately close the laboratory. I have to leave tomorrow.]

At this point, the log stopped abruptly.

Wang Chen finally found the information he wanted.

The meteorite that carried the virus was obviously the source of the zombie virus.

However, the task was not completed. Obviously, he still needed to find that meteorite.

Recalling that the log mentioned that all the monsters were trapped in the experimental area, Wang Chen immediately rushed to the test area.

A few minutes later, he arrived at the experiment holding area.

A thick metal door separated the experiment holding area from the office outside.

However, it was obvious that there was a problem with the metal door.

Red blood mist seeped out from it and slowly diluted into the air.

'It looks like that thing is inside!'

Wang Chen took a deep breath. He was about to open the door.

Squeak! Squeak! Squeak!

A terrifying cry suddenly sounded nearby. He looked over and saw rotting rat zombies crawling out of the corner.

What was unusual was that these rat zombies only stared at Wang Chen and did not attack him. They were like loyal guards, guarding the door behind them.

Wang Chen frowned and waved his hand, sending out a fireball that smashed into the group of rats.

Squeak, squeak!

Screams echoed throughout the laboratory as hundreds of rat zombies were killed in one strike.

Wang Chen's actions undoubtedly angered these rat zombies.

However, they still restrained themselves and did not make a move.

At this moment.

Roar!

A terrifying roar suddenly came from behind the metal door. Then, the rat zombies immediately pounced on Wang Chen as if they had received an order.

At this moment, Wang Chen finally saw a few holes leading to the outside at the corner of the experimental area.

Rat zombies were surging out of that place.

The ceiling, the walls, and the entire passageway…

Everywhere he looked, there were rats and zombies.

Boom! Boom!

Wang Chen threw out two Fireballs and instantly killed a large number of rat zombies.

[You have reached Level 18!]

However, those rat zombies were still rushing out, and their numbers seemed endless.

Wang Chen only felt his scalp go numb. Although these rat zombies were extremely fragile, there were so many of them. If he used a knife to cut them, he definitely wouldn't be able to cut them all!

He hurriedly retreated.

However, he would not miss such a good opportunity to level up.

Boom! Boom!

He threw a fireball spell as he retreated.

The three Fireballs exploded, and the blazing flames almost drowned the entire passage.

[You have reached Level 19!]

Another 1,000 plus points of EXP directly raised Wang Chen's level by one level.

"Again!"

Boom! Boom!

Fireballs kept exploding, killing all the rat zombies that were charging at them.

[You have reached Level 20!]

Another few thousand rat zombies were killed, and Wang Chen's level rose to Level 20.

[Detected that the Descender has reached Level 20. The Class System has been unlocked!]

[Professionals can use the Career Skill Roulette to change professions to obtain greater strength!]

The voice of the System Wizard sounded.

However, Wang Chen didn't have time to think about the Career Skill Roulette. His energy was almost depleted.

Those rat zombies were still rushing out.

'I'll retreat first!'

He did not dare to be greedy anymore. He turned around and ran.

If he was really surrounded by rat zombies, just thinking about it made Wang Chen's hair stand on end.

Rat zombies weren't like human zombies.

Even if there were tens of thousands of zombies, only a dozen of them could attack at the same time.

As long as he had enough stamina, he could continue fighting.

However, the rat zombies could attack hundreds of them at the same time.

Fortunately, the rat zombie was not as fast as Wang Chen, so he quickly shook it off.

He rushed all the way to the exit and used Fireball to blow up the desk blocking the door. He then activated his shield and drilled out.

Before Wang Chen could stand up…

Boom!

The Flying Flower Shield exploded, and Wang Chen felt as if his back had been hit by a hammer. The pain was so intense that he almost couldn't breathe, and he directly lay on the ground.

A pair of large black feet appeared a meter away from him.

The Eye of Insight immediately sent the monster's attributes back to Wang Chen.

[Giant Zombie (Elite)]

[Level: 18]

[Basic Attributes: Strength (57), Stamina (?), Agility (3), Charisma (2)]

[Skill: Bone-hardening]

"Strength +9!"

After seeing the monster's attributes, Wang Chen didn't even think about it. He directly added the remaining 9 free Attribute Points to Strength.

Then, he endured the pain and jumped up from the ground. He swung his sword at the giant two-meter-tall zombie in front of him.

Kacha!

The giant zombie could not dodge in time, and its skull was split in half by Wang Chen.

However, its tough bones also broke the blade in Wang Chen's hand.

Only then did Wang Chen see that the passage outside was already packed with zombies.

"Roar!"

At that moment, the rest of the zombies surrounded them.

"Get lost!"

Wang Chen was worried that the zombies behind him would catch up, so he didn't dare to continue killing zombies.

He activated the Flying Flower Shield and pushed through the zombie horde like a truck, then rushed out.
