At noon, Su Chen, who had finished lunch, found Han Qing and asked him to accompany Chen Mo to walk around Dragon City, and by the way, he explained about the mutated creatures around Chen Mo, so he set off from the north gate with Ye Yao.

Ye Yao and Chen Mo didn't deal with each other, and Su Chen didn't want to be caught between the two 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, which has been modified many times, has significantly improved its performance and appearance, and on the passenger seat, Ye Yao's little head is turning left and right, as if everything around is full of freshness.

"It's been a long time since we've been out together, how about spending the night together tonight?" Su Chen held the steering wheel in his hand and turned his head to look at Ye Yao.

"If you don't become a fourth-level immunizer and don't go back, I must surpass you!"

"Then it's a happy decision, Xiaoying stays in Dragon City, and I will rush back if necessary." Although Dragon City is developing rapidly, there are no forces around it that can pose a threat to Dragon City, but it is necessary to keep a hand.

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

"It was my fault some time ago, and I will take the time to spend time with my wife." Su Chen smiled lightly.

"You can just call me sir." Ye Yao's mouth pursed, and her expression changed again and again.

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

"There are no shortcuts, it's just that I've accumulated enough similar experience, and I need to meet some conditions to advance, otherwise I can't level up, just like you need to kill a second-level defensive zombie." Ye Yao explained.

"Feelings, you lied to me yesterday, you bad woman." Su Chen retracted his gaze and said.

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

"On what terms?" Su Chen said curiously.

"Kill a level 4 mutant creature with a perceptual skill! Among the people I have met, apart from you, only Chen Mo can do it, and I will definitely not go to him. Ye Yao accentuated her tone, and there was a great prejudice against Chen Mo in her tone.

“... Your conditions are much harsher than I did at the beginning, no wonder your combat power surpassed me at the beginning, but you have never been able to improve, it turns out that you are stuck here. Su Chen was thoughtful.

"Have you chosen your target?" Su Chen spoke again.

"Not yet, but I know the territory of several fourth-level mutant creatures, and I can't be sure if they have perceptual skills, so I need your help."

"Do you need to make up for the last stab, or will I just wipe it out?" Su Chen said.

"I'm not sure, it's better for me to kill it myself."

"Okay, then just make sure it's the object you need to hunt, and the last knife will be left for you."

"Thank you."

“... Don't say thank you between the two of us, it's embarrassing. Su Chen scratched his head, a little overwhelmed.

“...”

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

According to Ye Yao's words, Su Chen stopped the car and observed left and right.

Although it is a suburb, there are many buildings around, and although it is not as prosperous as the city center, it is much more prosperous than the metropolitan area of the city.

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

"Don't worry, there are still three miles of road, the road in front is blocked, let's go over." Ye Yao explained.

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

"This target is the strongest in my perception, and if nothing else, it is the strongest of the six level 4 mutant creatures I know, and the one most likely to possess perception skills."

Ye Yao paused and continued: "It's about five kilometers to the east here, and there is a fourth-level mutant creature, its strength is slightly weaker, should we use it to practice first?" ”

"No, when I clean it up, let's harvest the fourth-level mutant creatures together." Su Chen was full of confidence.

The combat power of mutant creatures of the same level is slightly stronger than that of the immune, and the higher the level, the greater the difference.

The larger the mutant creature, the stronger it will be after the level increases, and the zombie illustrated book provides basic information, and the actual information will have some changes, which is also explained by the zombie illustrated when prompting.

Even so, Su Chen, who had just been promoted to a fourth-level immunization, was not worried, he learned from the Zombie Illustrated Book that a fifth-level immunizer needed to accumulate 2,000 points of experience, and he had already surpassed 3,000.

To put it simply, although he was only promoted to the fourth-level immunizer yesterday, after a day, his foundation has been solidified, and his strength is considered a delicate child among the fourth-level immune, plus his skills and special skills, he can completely match the top fourth-level immune.

As for Ye Yao, Su Chen didn't need to protect her, once he fought with a fourth-level mutant creature, how could he give it a chance to hurt Ye Yao, as for the other third-level mutant creatures, with Ye Yao's strength, they were completely able to deal with it.

Su Chen was full of confidence, but his actions would not be reckless, and the two of them moved forward slowly, avoiding mutated creatures as much as possible along the way.

Su Chen walked about two miles, and the unique aura of the fourth-level mutant creature appeared in his perception, and its power was unconcealed, even if it was far away, it could be clearly sensed.

Based on perception alone, Su Chen was able to determine that the combat power of the fourth-level mutant creatures he was about to face was stronger than him, but after using skills and special skills, it was not certain who would win and who would lose.

"Yao, I've figured out its location, you stay here, and if the battle situation is unfavorable, retreat." Su Chen lightly held Ye Yao's small hand and said.

"A few layers of certainty." Ye Yao stopped and asked.

"If you rely on combat power alone, there is no hope, but there are six layers of certainty in the real fight." Su Chen estimated it and replied.

"Alright, I'm here waiting for your good news."

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

The sixth-layer grasp was Su Chen's nonsense, in fact, he didn't know the skills of the fourth-level mutant creatures, in order to avoid accidents, it would be better to keep Ye Yao away from the battlefield.

The fourth-level mutant creature did not conceal its aura, and within a mile, Su Chen's perception could easily lock on to its precise location.

Just yesterday, Su Chen was still shocked by the strength of the fourth-level immune, and today he sensed the fourth-level mutant creatures, but he felt unremarkable.

Su Chen quickened his pace, and all the mutant creatures that stood in his way were cut off by him.

Now that he couldn't gain experience by killing Level 1 mutant creatures, there was no need for him to waste time on them.

On the way, once Su Chen encounters a second-level mutant creature, he will still take the initiative to take action, after all, he doesn't know whether he will kill a second-level mutant creature after being promoted to a fifth-level immune creature and will not be able to gain experience.

If that's the case, each level will require a lot of experience, and there are fewer and fewer ways for him to gain experience, so it is necessary to accumulate experience before advancing the ranks.

As soon as Su Chen made a move, his aura was quickly detected by the fourth-level mutant creatures, and the powerhouses of the same level had an inexplicable sense of each other, and it discovered Su Chen for the first time.

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

Its reaction speed was slightly faster than Su Chen expected, and Su Chen gave up the idea of continuing to slaughter 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 as not to have time for Ye Yao to retreat after the defeat.

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

To the south of the street entrance, Su Chen took the lead in stopping, and the fourth-level mutant creature in the north also stopped.

It has been more than two months since the outbreak of the end times, and the fourth-level mutant creatures at this stage stand out from the hundreds of millions of mutant creatures, whether it is wisdom or combat power, they should not be underestimated.

Just as Su Chen stopped to observe it, it was also observing Su Chen, and at the same time ordered the mutated creatures around it to obstruct Su Chen.

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

---------------------------------------

Only from the information of the Zombie Illustrated Book, it is known that this mutant ape, which looks twice as big as an orangutan, not only has a huge appearance, but also has combat power beyond Su Chen's expectations.

Two skills, one special skill, the fourth-level mutant creatures at this stage are not simple characters!

Judging from Su Chen's perception and the information provided by the Hundred Treasure Eye, the combat power of the mutant ape is not inferior to Su Chen, if there is no experience potion to assist, even if Su Chen can defeat him, he will at least be seriously injured or even die together.

With just a brief glance, Su Chen defined it as the strongest existence among the mutated creatures he currently knew!

Even if it's a fourth-level Cerberus, it's just a younger brother compared to it.

Su Chen didn't dare to slack off, and while dodging the mutated creatures around him, his brain quickly calculated how to deal with it.

It's worth mentioning that its special skills are heavy and draining, and once used, it quickly goes into a weakened state!

And it didn't know that Su Chen had a zombie guide, and the effect that its consciousness sweep could have was extremely not optimistic.

Standing beside the mutant ape, which was nearly four meters tall, Su Chen was like a stunted child.

The mutant ape is huge, but it doesn't affect its speed and agility, and it will be a tough battle to tell.
