I'm invincible since the end of the world

After seeing these plus signs, Lin Xinghai clicked on the "+" sign behind the advanced shooting skill proficiency without any hesitation.

"Ding! Do you want to spend 1,000 blood energy to improve proficiency?"

As Lin Xinghai chose "Yes", the proficiency of advanced shooting skills increased by 1%, and then a stream of knowledge also poured into his mind.

Among these knowledge, only a small part is about shooting skills, and the rest is almost all about how to better condense and compress one's own blood energy and inject it into the bullet.

Before, Lin Xinghai could only compress 1% of the blood energy, but now he can condense 2% of the blood energy and compress it into a bullet.

"Very good, let's see how much proficiency can be clicked." Lin Xinghai felt the memory in his mind, and it was exactly as he guessed, and he immediately clicked up without hesitation.

Soon he spent another 18,000 blood energy and directly clicked the proficiency to 20%, and the "+" sign disappeared.

At this time, Lin Xinghai was able to compress 20% of his blood and qi power and burst it out in one breath.

You should know that his total blood and qi power is not small, reaching 2833 points, 20% is 566 points.

Although this simple condensation of blood and qi power has no bonus, the damage caused is considerable due to the large total amount.

If these blood and qi powers are compressed into a depleted uranium armor-piercing bullet, it is hard to say whether it can deal with a fourth-level mutant zombie comparable to the God and Demon Realm, but if it is a third-level mutant zombie at the level of the Shaping Realm, even the most defensive iron-clad zombie can definitely kill it with one shot.

Of course, the improvement of his own strength is only secondary to Lin Xinghai. The most important thing is that this compression secret method finally has a practical effect.

"The next step is to find a way to sell this compression secret method at a good price. It's a pity that Lao Zuo is not here, otherwise I wouldn't have to go through so much trouble. Now I can only go to the school's top management." Lin Xinghai thought.

However, he was not in a hurry to go out, but instead set his eyes on the system panel again, and spent tens of thousands of blood and energy to upgrade all the martial arts that could be improved.

With the increase in martial arts proficiency, his strength has once again improved a lot, just like the move of stepping on thunder that comes with the Thunder Step. If it is used, it can now inject 200 points of blood and energy, and instantly burst out 2000 points of attack power and movement speed.

Under the condition of time power acceleration, the speed that can be burst out is terrifying.

In addition, various moves like the Wind and Thunder Gun Method, such as Thunderstorm or Sky Thunder Strike, have a certain improvement in attack power.

Of course, the one with the largest improvement is definitely the Thunder God Spear, which is the bottom-line means.

However, it is hard to say how much it has been improved, but it is definitely a move that can threaten the strong men in the God and Demon Realm.

"Now that I encounter a mutant zombie in the early stage of the fourth level, I should not be in a panic and flee. I can try to fight it one or two." Lin Xinghai felt his own changes and secretly evaluated his own combat power.

Of course, even if he imagined the best situation, he only dared to guess that he would fight for a moment. As for winning, he didn't dare to think about it at all.

The levels on the Abyss Plane are completely corresponding to their humans.

The first and second level mutant zombies correspond to the Blood Qi Realm and the Quench Viscera Realm. This level is completely for laying the foundation and is not too strong.

As for the third level mutant zombies, they correspond to the Body Shaping Realm. In the past, except for the stronger body, they did not have any special abilities.

But now that they no longer hide their strength, these mutant zombies will have an additional ability.

For example, the "Death Claw", when it bursts out with full force, the claws on the hand will burst out a cutting force, which will increase the attack power.

As for the other mutant zombies, they are not much different, such as the "Giant Arm", which can make the arm burst out a strange huge force.

For example, the "Hunter" has the ability to actively increase speed.

Of course, these new abilities are more like strengthening their original abilities, so overall they are not too difficult to deal with.

However, when these mutant zombies reach the fourth level, they are completely different. It is like when humans reach the God and Demon Realm and can display a complete God and Demon Body, their strength will directly undergo a qualitative transformation.

A God and Demon Realm strongman can defeat hundreds of Body Shaping Realm.

Similarly, a fourth-level mutant zombie can also defeat hundreds of third-level mutant zombies.

Because after the mutant zombies break through the fourth level, they can mobilize the Yuanli in the Yuan Crystal in their bodies to fight.

And this Yuanli is like the power of blood and qi, which can be used for both offense and defense.

In conjunction with the mutant zombies, the already terrifying physical fitness is simply no weakness.

Like Lin Xinghai facing the first, second and third level mutant zombies, as long as he finds an opportunity, he can harvest their lives with one bullet.

But the fourth-level mutant zombies, after being able to display Yuanli, completely make up for this weakness.

Unless you can break their Yuanli defense with absolute attack power, it is difficult to hurt them fundamentally.

And that requires at least the power of the God and Demon Realm to do it.

Thinking of this, Lin Xinghai shook his head. He was only in the middle stage of the Tempering Body Realm now. It was really a bit of a self-inflicted trouble to think about these problems.

He pushed open the door and walked out, intending to find Jian Hua, the head teacher, first, and then contact the school's senior management.

But as he opened the door, he was surprised to find that not only were several members of the Xinghai team outside, but even Zuo Wenyao was there.

"Teacher Zuo, why are you back?" Lin Xinghai asked in surprise.

"I came back injured, and then asked your girlfriend for treatment." Zuo Wenyao said unhappily.

"Ah! Teacher Zuo, you are injured. Is the injury serious?" Lin Xinghai was a little surprised.

He had just seen Zuo Wenyao more than an hour ago, and the other party was fine at the time. He was injured in such a short time, which forced him to re-evaluate the situation on the front line.

"Don't change the subject first. Your girlfriend's ability can actually heal the injuries of the gods and demons. Why didn't you say this earlier?" Zuo Wenyao said with some resentment.

Recalling the situation when he was asked by other gods and demons before, he didn't know anything, and he was a little angry.

"You haven't asked me before! Besides, we don't know why you are so short of healing psychics." Lin Xinghai spread his hands and said.

He also met Chen Yushi before, and from the other party's attitude towards Liu Miaomiao, he knew the importance of Liu Miaomiao's healing ability.

Zuo Wenyao was choked and didn't know how to question for a while.

At this time, Lin Xinghai took the initiative to speak, "Teacher, I have developed a compression secret method, which may change your current battle situation."
