At noon, after lunch, Su Chen found Han Qing and asked him to accompany Chen Mo for a walk around Dragon City. By the way, he explained about the mutated creatures around Chen Mo, and then set off from the north gate with Ye Yao.

Ye Yao and Chen Mo don't deal with each other, and Su Chen doesn't want to be caught between them in this operation.

Chen Mo understood what Su Chen meant. He chatted with Su Chen for a few words and then left with Han Qing.

Outside the north gate, the z3 off-road vehicle has been modified many times. Its performance and appearance have been significantly improved. In the passenger seat, Ye Yao's little head turned around, as if everything around her was full of freshness.

"It's been a long time since we went out together. How about spending the night together tonight?" Su Chen held the steering wheel and turned to look at Ye Yao.

"If you don't go back until you become a level four immune person, I will definitely surpass you!"

"Then it's a happy decision. Xiaoying will stay in Longcheng. I will rush back if necessary." Although Longcheng is developing rapidly and there are no forces around it that can pose a threat to Longcheng, it is necessary to keep a guard up.

"Drive slowly, it's hard to go out with you. I don't know when the next time will be." Ye Yao muttered.

"It was my fault some time ago. I will take time to spend time with my wife." Su Chen said with a smile.

"You might as well call me Sir." Ye Yao pouted, her expression changing again and again.

"Yao, tell me about your shortcut to promotion, I'm very interested." Su Chen changed the subject.

"There is no shortcut, but I have accumulated enough similar experience. Some conditions need to be met to advance, otherwise you cannot upgrade, just like you need to kill the second-level defensive zombies." Ye Yao explained.

"You were lying to me yesterday about your feelings, you bad woman." Su Chen looked away and said.

"No, it's just that the conditions for my promotion are a bit harsh. No one can help me except you." Ye Yao shook her head and said.

"What conditions?" Su Chen asked curiously.

"Kill a fourth-level mutated creature with sensory skills! Among the people I have seen, apart from you, only Chen Mo can do it, and I will definitely not go to him." Ye Yao emphasized her tone and said to her. Chen Mo is very prejudiced.

"...Your conditions are much more stringent than mine. No wonder you surpassed me in combat power but still couldn't improve. It turns out you're stuck here." Su Chen thought thoughtfully.

"Then have you chosen your target?" Su Chen asked again.

"Not yet, but I know the territory of several level four mutated creatures. I can't be sure whether they have perception-type skills. I need your help."

"Then do you need to make the last stab, or should I directly kill it?" Su Chen said.

"I'm not sure. It's best if I kill it myself."

"Okay, then as long as it is determined to be the target you need to hunt, I will leave the last knife to you."

"Thanks."

"...Don't say thank you between the two of us, it would be awkward." Su Chen scratched his head, feeling a little at a loss.

"..."

An hour and a half later, somewhere in the suburbs of Nanshi, an area Su Chen had never been to.

According to Ye Yao's words, Su Chen stopped the car and looked around.

Although this is a suburb, there are many buildings around it. Although it is not as prosperous as the urban center, it is much more prosperous than most urban areas.

There was no third-level mutant creature in Su Chen's perception, let alone the unique oppression of fourth-level mutant creature. Su Chen observed it for a while and said: "Where is it?"

"Don't worry, there are still three miles to go. The road in front is blocked. Let's walk over." Ye Yao explained.

"...I thought there was something wrong with my perception." Su Chen said.

"This target is the strongest in my perception. If nothing else, it is the strongest among the six level four mutant creatures I know, and it is also the mutant creature most likely to have perception skills."

Ye Yao paused and continued: "About five kilometers away from here to the east, there is a fourth-level mutant creature. It is slightly weaker. Should we practice with it first?"

"No, wait until I take care of it, and we will harvest the fourth-level mutated creatures together." Su Chen was confident.

Mutated creatures of the same level have slightly stronger combat power than those who are immune. The higher the level, the greater the difference.

The larger the mutant creature is, the stronger it will be as its level increases. The Zombie Illustrated Manual only provides basic information, and the actual information will have some changes. This is also stated in the Zombie Illustrated Manual when prompted.

Despite this, Su Chen, who had just been promoted to the fourth level of immunity, was not worried. He learned from the zombie illustrated book that he needed to accumulate 2,000 experience points to advance to the fifth level of immunity, and he had already exceeded 3,000.

To put it simply, although he was only promoted to the fourth level immune person yesterday, after one day, his foundation has been solidified, and his strength is considered to be the most delicate among the fourth level immune persons. In addition, his skills and special skills can completely match him.

The top level four immune person.

As for Ye Yao, Su Chen doesn't need to protect her. Once he gets into contact with a fourth-level mutant creature, how can he give it a chance to hurt Ye Yao? As for other third-level mutant creatures, Ye Yao's strength is completely capable of dealing with it.

Su Chen was confident but would not act recklessly. The two of them moved forward slowly, avoiding mutant creatures as much as possible along the way.

Su Chen had walked about two miles when he sensed the unique aura of a fourth-level mutated creature. Its power was unmistakable and could be clearly sensed even from a long distance.

Based on his perception alone, Su Chen was able to determine that the level four mutated creature he was about to face was more powerful than him, but after using skills and special skills, it was not certain who would win.

"Yao, I have figured out its location. You stay here and retreat if the battle situation is not favorable." Su Chen gently held Ye Yao's little hand and said.

"How confident are you?" Ye Yao stopped and asked.

"Based on combat power alone, there is no hope, but in a real fight, there are six levels of certainty." Su Chen made an estimate and replied.

"Well, I'll wait for your good news here."

Su Chen nodded, let go of Ye Yao's little hand, and moved forward alone.

Su Chen was talking about the sixth level of certainty. In fact, he did not know the skills of level four mutant creatures. In order to avoid accidents, it was better to keep Ye Yao away from the battlefield.

The fourth-level mutated creature did not conceal its aura, and within one mile, Su Chen's perception could easily locate its precise location.

Just yesterday, Su Chen was shocked by the power of level four immune beings. Today, he sensed level four mutant creatures, but found them to be unremarkable.

Su Chen quickened his pace and cut off the heads of any mutated creatures that blocked his way.

Nowadays, there is no way to gain experience by killing level one mutated creatures, so there is absolutely no need for him to waste time on them.

On the way, once Su Chen encounters a second-level mutated creature, he will still take action. After all, he does not know whether he will be able to kill the second-level mutated creature and gain experience after being promoted to a fifth-level immune person.

If that's the case, each level up requires a huge amount of experience, and there are fewer and fewer ways for him to obtain experience. It is necessary to accumulate experience before advancing.

As soon as Su Chen took action, his breath was quickly detected by the fourth-level mutated creature. Strong people of the same level have inexplicable reactions to each other, and it noticed Su Chen immediately.

Su Chen could sense that a powerful aura was rushing towards his direction.

Its reaction speed was slightly faster than Su Chen expected. Su Chen gave up the idea of ​​continuing to kill the second-level mutant creatures and quickly faced the fourth-level mutant creatures rushing towards him.

Su Chen had to distance himself from Ye Yao so that Ye Yao would not have time to retreat after the defeat.

Half a minute later, Su Chen, who was moving at full speed, met the fourth-level mutated creature at the street entrance.

To the south of the street entrance, Su Chen was the first to stop, and the fourth-level mutated creature to the north also stopped.

It has been more than two months since the apocalypse broke out. The current level four mutated creatures stand out from the hundreds of millions of mutated creatures. Regardless of their intelligence or combat power, they cannot be underestimated.

Just when Su Chen stopped to observe it, it was also observing Su Chen and at the same time ordered the surrounding mutated creatures to stop Su Chen.

It was very simple for Su Chen to check its information. The Baibaoyan only needed to scan its body to get its basic data, and it would not be hindered by the mutated creatures around it at all.
