I started with a seed, luckily I have probability glasses

Cheng Nannan fell into deep thought and spoke after a while.

"I, I don't think I did anything. It was triggered after I killed a purple enhanced biochemical experiment."

Li Chuan scratched his head.

Killing a purple biochemical experiment triggered it? That shouldn't be the case. I've killed at least eight hundred of those monsters, if not a thousand. If it could be triggered, Lin Yaoyao and I should have triggered it long ago.

"Did you do anything else besides killing that monster?"

Cheng Nannan frowned and thought, then said uncertainly.

"I released my Bai Ting to gain some experience, but after that purple experiment appeared, I was afraid Bai Ting would get hurt, so I took him back."

Bai Ting is Cheng Nannan's new pet, a snow-white black dragon lizard.

The reason why the black dragon lizard is snow-white all over is due to Zhang Heng’s dangerous attempt.

Could the side quest be related to pets? Li Chuan thought it was impossible.

Cheng Nannan continued to reminisce.

"Before, the two of us were killing test subjects on this street, and we didn't do anything else."

The more Li Chuan thought about it, the more confused he became.

Everyone is killing biochemical experiments, so why is it that only Cheng Nannan triggers the side quest? What is the difference between her and the others?

Roar--

Just as he was thinking about it, a low-level biochemical experimental subject, the weakest zombie, crawled out from the sewer well and pounced on Li Chuan without knowing his own limitations.

Cheng Nannan couldn't let that kind of low-level thing disturb her president's thinking, so she immediately rushed forward with a long knife and killed the weakest zombie with a few strokes.

Li Chuan's eyes gradually brightened as he watched Cheng Nannan killing the zombies.

The difference is found!

The difference is that Cheng Nannan killed almost all the weak, low-level experimental subjects, while Lin Yaoyao and I only killed the strong ones! This is the difference between Cheng Nannan and me! I didn't kill enough low-level experimental subjects!

"I think I know what's going on. Wait here for me. I'll go and verify it and come back soon!"

Lin Yaoyao and the other two girls were confused, but Li Chuan had already rushed out very far away with a dagger in his hand.

[Ding, kill lv34, low-level biochemical experiment (elite) *1...]

[Ding, kill the lv34, low-level biochemical experiment...]

……

Li Chuan rushed at high speed on the streets of Beicheng, killing any low-level biochemical experimental subjects he encountered, with extremely swift movements.

After about half an hour, Li Chuan didn't know how many times he had killed people in the nearby streets, from East Street to West Street, from South Street to North Street. In short, he had killed 500 low-level biochemical experimental subjects.

Just when Li Chuan felt there was no hope, the system panel that triggered the side quest suddenly appeared.

[Ding, you have triggered the side quest 'The Long Relief'.]

[Side Quest: Long Liberation]

[Mission Difficulty: Intermediate]

[Go to the garbage dump area and kill a lot of mutants! No one is born a rotten monster! I am not one of them!]

【当前击杀数量：低级变异者0/1000、中级变异者0/500、高级变异者0/100】

[Quest Rewards: Experience Points*2000000, Mysterious Key*1, Part of the secrets of Gazing Island.]

[Mission Penalty: Level -10, randomly destroy half of the player's items.]

[Task time limit: 10 days]

"Is that so? The condition for triggering this side quest is to kill a certain number of experimental subjects of various grades. If I had known it was so simple, why would I have taken that risk yesterday?"

On the second floor of a building on the street, the bored Lin Yaoyao suddenly became excited when she saw Li Chuan.

"You're back, Brother Chuan. How's it going? Did you find a solution?"

Li Chuan appeared beside the three women and nodded.

"It's been triggered. You only need to kill about 500 low-level biochemical experiments yourself. But you must do it yourself. Your teammates can't kill them."

Lin Yaoyao jumped up happily.

"Great! Brother Chuan, you are amazing."

Li Chuan rubbed Loli's head.

"While there's still time, go and kill 500 low-level biochemical test subjects yourself. Zhang Heng and Feifei are supportive, so I'll help them kill enough."

Lin Yaoyao couldn't wait any longer, and nodded vigorously, then disappeared.

"Okay!"

Because the subjects to be killed were low-level biochemical experimental subjects, Li Chuan did not enter the sewer this time. Instead, he killed the zombies and zombie dogs wandering on the streets nearby.

But in order to kill faster, Li Chuan and the other three took off the Ghost Blade Society's armbands and put them into their backpacks.

After half an hour.

Cheng Nannan once again sent a zombie with low health in front of Yuan Feifei, who killed it with an ordinary light bullet.

Yuan Feifei frowned.

"President, I've calculated that I've killed at least five hundred low-level biochemical test subjects, but the side quest hasn't been triggered."

Zhang Heng also nodded in agreement.

"Yeah, I didn't trigger it either."

Li Chuan kicked a zombie away and said decisively.

"Then take the Ghost Blade Society armband, let's go into the sewers and kill another 500 of the other grades!"

Li Chuan was certain that this side quest was definitely related to the number of experimental subjects killed, but the specific number of each grade was still uncertain.

The four of them donned Ghost Blade Club armbands and plunged into the sewers, luring monsters, killing them, gaining experience points, and picking up dropped equipment.

After a while, Lin Yaoyao, who had successfully triggered the side quest, also entered the sewer and joined the ranks of hunting monsters.

Yuan Feifei counted the number of monsters she had killed.

"Three hundred blue ones and one hundred and eighty purple ones."

"Three hundred and forty blue ones, and two hundred purple ones."

[Ding, you have triggered the side quest 'Long Relief']

[Side Quest: Long Liberation]

[Mission Difficulty: Intermediate]

[Heading to the garbage dump area...]

"President! I triggered a side quest."

Li Chuan's reply came from the dark sewer.

"Well done! Zhang Heng has also triggered it, right? Well! Then there's no need to hold back, kill the monster with all your might!"

"Okay, President!"

"Got it! Mr. President."

……

[Ding, Phantom Master experience points have been maxed out, level +1, current secondary occupation level: lv44.]

[Ding, your pet 'Mysterious Cat' has reached the maximum experience value, level +1, current level: lv44.]

At around four o'clock in the afternoon, Li Chuan's main and secondary professions as well as Xiao Huang were all upgraded to level 44.

It just so happened that it was time to collect the harvest as agreed with Zi Xiangwang.

The situation in the Beicheng ruins is similar to the situation in the Wancheng ruins before. There are two sides confronting each other, one strong and the other weak. It is said that they were originally evenly matched, but on the day of "Doomsday", one of the forces was particularly unlucky. Before the personnel could disperse, most of the players were killed by the light of sanctions. Then they fell into a disadvantage and could not recover for a long time.

The weaker side was very decisive. Seeing so many genetic warriors standing behind Zi Xiangwang, they decisively handed over 200,000 kal and all kal stores above silver grade.

But the stronger side is not so easy to scare.

They were confident of their large numbers and great strength, and not only did they not give Zi Xiangwang any face, they also tried to treat Zi Xiangwang and others as bosses and surround and kill them in this reserve city.
