Slaughter the Zombie Rats! A Great Harvest for All!

"Let's not talk about these things for the time being." Wang Chen waved his hand and said, "There are only those zombie rats in the laboratory now." However, the zombies will soon gather outside.

"We have to hurry! Brother Shi, do you want to go with us? Those zombie rats were the best opportunity to upgrade quickly."

Wang Chen looked at Shi Tang.

Shi Tang hesitated for a moment. "My energy has been exhausted, so I won't trouble everyone!"

He didn't know if the upgrade was real or not. He just wanted to save his life.

In addition, he had no value to Wang Chen and the others now. He didn't want to test whether Wang Chen and the others would use him as bait at a critical moment.

"Then, do as you please."

Seeing this, Wang Chen didn't insist.

Now, he had enough energy to cast more than a hundred fireballs.

Han Ying and the others had over a hundred fireballs in total.

In addition to that, killing the zombie rats would also allow everyone to level up rapidly. It wouldn't be a problem even if the number of zombie rats increased.

"We'll set off in half an hour. Be prepared," Wang Chen said to everyone and left.

He found a washroom with water, washed the Zombie Crystals, and swallowed them.

To Wang Chen's surprise, the effect of the Rank 1 Zombie Crystal began to weaken.

All the Rank 1 Zombie Crystals added together only increased his attributes by one point. Strength +2, Stamina +3, Agility +5, Spirit +2.

On average, a single crystal could only increase his attributes by one point.

After that, Wang Chen swallowed the Rank 2 Zombie Crystal.

[You have consumed a Zombie Crystal (Stage 2). Strength +3, Agility +5.]

'The effect is not bad, but it's a pity that Rank 2 Zombie Crystals aren't easy to get.'

Wang Chen felt somewhat regretful.

Level 30 Lord-rank monsters were considered the best among the zombies, and there weren't many of them in the city.

Half an hour later, everyone set off on time.

"We must come back later. Brother Shi, please make the necessary plans," Wang Chen reminded Shi Tang.

Since Shi Tang did not want to join them, then he would not care about Shi Tang's life or death.

Shi Tang's expression changed slightly. He understood what Wang Chen meant.

"Thank you for your reminder, Brother Wang. I also plan to go out in a while."

He smiled and nodded.

With his skills, as long as he did not encounter any accidents, it would not be difficult for him to escape.

…

In the White Birch Virus Laboratory, Wang Chen walked to the front and brought them to the door.

"I'll go in and lure those guys out, then block the door and kill them!" he said in a deep voice. "There are a lot of zombie rats. Don't be afraid."

"Don't worry, Brother Wang. Since we're here, we definitely won't run!" Duan Lang said confidently.

"Trust me, you won't lose out."

After Wang Chen said that, he walked deeper into the laboratory. He came to the experimental area with familiarity.

Roar!

A low roar came from inside.

The voice was filled with anger as if it was extremely dissatisfied with Wang Chen's repeated disturbances.

Wang Chen sneered, "What's wrong? Are you unhappy? Then, why didn't you come out and fight with me? Why did you hide behind these rats?"

His taunting was obviously effective.

Screech!

Following that, a sharp roar came from the darkness, causing Wang Chen to feel a little dizzy.

At the same time, an overwhelming number of zombie rats also rushed out and rushed toward Wang Chen.

"That's right! Follow me!" Wang Chen laughed and turned to run.

The zombie rats chased after him relentlessly, and he quickly led them to the laboratory door.

"F*ck! Isn't this too many?"

Looking at those zombie rats that were as big as ordinary cats behind Wang Chen, Duan Lang felt his heart trembling.

"There are as many rats in a city as there are humans. These should be only a portion of them," Qi Yi said faintly,

"Stop talking nonsense and kill all these zombie rats!" Han Ying's face was filled with disgust. She hated rats the most.

Boom! Boom!

Fireballs flew into the door and smashed into the group of rats behind Wang Chen.

Although their skills were not as powerful as Wang Chen's, every fireball that landed still burned hundreds of zombie rats to ashes.

"Let's do it! Chen Feng, summon your Berserk Bone Locust to guard the door and kill the zombie rats that have escaped." Wang Chen also rushed out and stood in front of everyone.

Boom! Boom!

Fireballs exploded among the zombie rats as if they were free.

A large number of zombies were killed.

More than 20 agile Berserk Bone Locusts were guarding the door, and the zombie rats that were lucky enough to rush out were quickly killed.

Everyone's EXP and Spirit Points rose rapidly.

"Hahaha! It feels so good! I've already leveled up by 5 levels!" Duan Lang's face was full of smiles. He had never thought that he could level up so quickly.

"I've risen by 5 levels too." Fu Zhe was also a little excited.

The two of them were of lower levels and required less EXP, so they leveled up faster.

The Attribute Points gained from leveling up also replenished everyone's energy, maintaining the absolute suppression of the zombie rats.

"Be careful, these beasts are coming up from behind!"

At that moment, Wang Chen suddenly realized that some zombie rats had come up from behind.

"Fu Zhe and I will take care of the door. You guys take care of the rear," he said in a deep voice.

Now that the number of zombie rats had been greatly reduced, he could barely defend the gate area alone. With Fu Zhe's help, it was not a problem to guard the direction of the laboratory.

"Leave it to me!"

Chen Feng's eyes turned red as he immediately turned to deal with the zombies behind him.

He was worried that he wouldn't be able to win against Wang Chen, but the zombie rats came from behind, which was exactly what he wanted.

Boom! Boom!

Blazing fireballs exploded continuously.

A few minutes later, under the bombardment of hundreds of fireballs, the zombie rats were completely repelled, leaving charred corpses on the ground.

"I'm on Level 20!" Chen Feng could not help but roar in excitement. He had reached Level 20 and had more than 1,000 EXP.

"Little Feng, you're not the only one on Level 20." Duan Lang was in high spirits.

Wang Chen's gaze swept across the group. Other than Fu Zhe, Qi Yi and Han Ying had also reached Level 20.

Among them, Han Ying had accumulated more than 3,000 EXP. As long as she changed her class, she could immediately level up to level 1.

Apart from that, everyone's Spirit Points had also accumulated to an extremely terrifying number.

Fu Zhe, who had the least, had more than 5,000 Spirit Points. Han Ying and Chen Feng had the most, both with more than 9,000 Spirit Points.

However, compared to him, these guys' gains were completely insignificant.

He glanced at his panel and saw 

[EXP: 48,534]

[Spirit Points: 46,433]

He had killed tens of thousands of zombie rats alone.

In total, the six of them had killed more than 30,000 zombie rats.

"Alright, you guys can leave for now! Leave the rest to me!"

Wang Chen looked at the laboratory that was filled with the stench of corpses.

This amount of experience was enough to raise his level by a large margin.

At that time, the guy hiding in the experimental area should not be a problem.
