I'm invincible since the end of the world

Lin Xinghai's arm trembled, not because of fear or nervousness, but because of excitement.

He also has a system.

At this time, a translucent light and shadow screen appeared in front of him, on which the option of absorbing blood energy appeared.

Is this still necessary to consider?

He immediately chose yes!

The next moment, Lin Xinghai felt a strange feeling coming from his arm, as if some kind of energy entered his body through his arm.

At the same time, he also found that the wound on the back of the zombie's head, which was originally bleeding, had dried up directly.

Not only the wound, but the zombie's skin was also a little pale, as if all the blood in the body had been drained.

"This!" Lin Xinghai was startled. He pinched the flesh and blood at the wound with his hand, and really couldn't squeeze out a drop of blood.

"This blood energy, can't it be the blood in the zombie's body!" He had a guess in his heart, and at the same time, he looked around calmly.

Fortunately, no one paid attention to his situation here. After all, the zombie's wound had appeared for a while, and it was normal to stop bleeding now.

Moreover, the skin of zombies is pale, so if it is a little whiter, it will not be noticed if you don't look closely.

"Ding! Congratulations to the host for absorbing 1 point of blood and energy. Open the attribute panel function and start the main task."

As the system prompt sounded, the dialog box in front of Lin Xinghai turned into an attribute panel.

Host: Lin Xinghai

Constitution: 7 points

Strength: 7 points

Speed: 9 points

Blood and energy: 1 point

Genetic optimization degree: 9%

"Could it be that I am a speed player?" Looking at his attribute panel, Lin Xinghai muttered.

However, there was no one for him to refer to, and he didn't know whether his basic attributes were good or bad.

So after glancing at the attribute panel, he looked at the task bar below.

Main task: Please ask the host to collect 10 points of blood and energy.

Description: Blood and energy is the foundation of improving strength, the more the better.

Reward: Open the exploration function.

Task progress: 1/10.

After reading the task, Lin Xinghai couldn't help but show his joy. If he wanted to complete such a task under normal circumstances, it would probably not be easy.

But here, zombies are everywhere!

He did it as he thought. He stood up calmly and walked towards a zombie not far away.

This time he studied it. If he touched other parts of the zombie, the system would not react.

Only when he touched the bleeding wound would the system prompt pop up.

"It seems that it can be confirmed that even if the blood power is not equal to blood, it must come from blood."

Open the attribute panel, task progress: 2/10.

Lin Xinghai was immediately full of energy and soon touched 5 more zombies. At this time, the task progress has reached 7/10.

As long as he touched 3 more zombies, the main task would be completed.

But what he didn't know was that Roger had been secretly observing him.

The content of this "First Lesson" not only gave the members of the shelter a warning, but also tested their courage.

For an organization like the mercenary group that needs to fight zombies, courage testing is the top priority.

Roger originally intended to recruit Lin Xinghai, so of course he had to observe his courage carefully.

So, when he saw Lin Xinghai lining up to touch the zombies, Roger couldn't help but nod secretly.

However, when Lin Xinghai took the initiative to touch the second zombie, the expression on his face became subtle.

But Roger didn't expect that this was just the beginning.

Then, Lin Xinghai actually touched the zombies around him one after another. The more zombies he touched, the more interesting the expression on Roger's face was, "This man won't have necrophilia!"

And when Lin Xinghai touched the seventh zombie, Roger couldn't help but walked over, "What are you doing?"

Seeing Roger suddenly blocking in front of him, Lin Xinghai was shocked.

However, he had expected that his abnormal behavior would be noticed by someone with ulterior motives, so he said the reason without changing his face.

"I'm a little surprised. These zombies were obviously killed by bullets through their heads, but why did they have to cut open the back of their heads afterwards?"

The strange expression on Roger's face suddenly turned into surprise. It was good enough to keep a normal mind when touching zombies for the first time.

But Lin Xinghai not only found the abnormality, but also took the initiative to seek the answer.

At this moment, Lin Xinghai's importance in Roger's heart instantly rose to a higher level.

"Very good! If you want to survive in the end of the world, your insight is indispensable. As for why you have to cut open the back of the zombie's head, I can also tell you the reason, that is..."

"Don't tell me." Lin Xinghai interrupted hurriedly: "I want to find the answer myself."

What a joke, you tell me the answer, what reason do I have to continue to touch the corpse?

Roger hesitated slightly, showing an approving look, "You are really better than I thought."

Seeing that this level was passed, Lin Xinghai breathed a sigh of relief and hurried to the next corpse.

Soon, he touched 3 more zombies. When the task progress reached 10/10, the system sound sounded again.

"Ding! Congratulations to the host for completing the main task, the exploration function has been opened. Another 10 exploration times will be awarded."

Lin Xinghai hurriedly opened the attribute panel and found that there was an additional exploration skill behind the character attributes.

Detection Technique: Consumes blood and energy to detect the target's attributes. The higher the target's strength, the more blood and energy it consumes. Note: No blood and energy is consumed in the first 10 detections.

In addition to the addition of a detection technique, the main task has also changed.

Main task: Kill 100 zombies.

Note: Taking shortcuts is only temporary. If you want to obtain blood and energy, you still need to rely on your own strength.

Reward: None.

Seeing the reward for this task, Lin Xinghai's forehead suddenly had a black line. What the hell is the reward "none"?

Since there is no reward, why should he complete this task?

However, he found out that he had to do this task because he would definitely face zombies.

And if he didn't complete this task, the main task behind it would not be updated, which was the worst.

I was feeling depressed when I suddenly found that there was another change on the attribute panel.

Genetic optimization degree: 9%+

Yes! There is a + sign after 9%.

Lin Xinghai clicked it immediately.

"Do you want to consume 1 point of blood power to improve the degree of gene optimization?"

Lin Xinghai's heart skipped a beat and he quickly chose yes!

The next moment, a warm current appeared out of thin air, spreading to his entire body, making him extremely comfortable.

But he didn't have time to enjoy this feeling, and immediately looked at the attribute panel.

Host: Lin Xinghai

Constitution: 8 points

Strength: 7 points

Speed: 10 points

Blood power: 9 points

Gene optimization degree: 10%+

Lin Xinghai's face suddenly showed joy, the degree of gene optimization increased by 1%, and both physique and speed increased by 1 point.

"This blood power is indeed the root of improving strength!"

Having found a way to improve strength, Lin Xinghai did not hesitate and immediately added all the remaining blood power to gene optimization.

The warm current that appeared this time was even more terrifying, as if there was a fire burning in his body, but he could also clearly feel that his body was strengthening at a terrifying speed.

The attribute panel in front of him changed again.

Host: Lin Xinghai

Constitution: 15 points

Strength: 13 points

Speed: 19 points

Blood Force: 0 points

Gene Optimization Degree: 19%+

Blood Force is cleared, and the gene optimization degree is increased from the initial 9% to 19%. At the same time, various attributes have also been greatly improved.

Looking at the three attributes and the different improvements, Lin Xinghai's face showed a thoughtful look.
