The pressure did not increase all the time, and when it increased to a balanced position, Xu Zhen had already drunk the third bottle of potion, and at this time he suddenly felt that he had been punched, and then Xu Zhen kept feeling beaten, if he hadn't noticed the place where he was beaten, the fluctuation of the air, Xu Zhen would have gone offline, and see if it was that bastard who took advantage of his inattention and attacked himself in reality.

After a period of time, Xu Zhen has become accustomed to the feeling of blowing—in fact, he has become numb. The last bottle of potion went down, Xu Zhen's physical training had reached a critical moment, many people couldn't go through four processes at once, and most people relaxed in the fourth process, but the effect became worse. Xu Zhen couldn't feel the oppression from the outside world, but a tingling feeling arose from his bones, and he wanted to reach out to scratch it, but the prompt sounded, and he gave up scratching.

Finally, I survived the itching period, exhaled a deep breath of exhaust gas, and inhaled again, feeling that the whole person was alive. There are no sequelae after strength training, and I feel very energetic, energetic, and have endless strength. At this time, the physical training should have ended, but it was a new beginning for Xu Zhen.

A cool air flow appeared in Xu Zhen's body, wandering around, passing through the place was very comfortable, feeling that someone was massaging him, and finally flowing through the brain and flowing into the heart, the brain was clear, you could easily feel your physical condition, and you could even feel the peristalsis of the internal organs.

Eventually, the gas flowing into the heart is consumed, and the heart beats vigorously, but the heart rate decreases. I clenched my fist, and I felt that my strength was stronger, no, not stronger, and my strength could be fully exerted. When I threw a punch before, I always felt that I couldn't use my strength, and it turned out that the lack of strength in my body limited the play of strength.

[Detects that you have enough dark energy, whether to start the second-level constitution enhancement]

"Isn't the training room graded? Why can Level 2 attributes be enhanced in Level 1 training rooms? Well, is there any difference between training and strengthening? "Xu Zhen grasped the key point, all the previous methods of enhancing attributes were called training, but here they are called strengthening, what is the reason? And if it can be universal, then why do you divide it into grades!

I didn't expect the system to give an explanation.

[Dark energy enhancement is not limited by scenes, the hierarchical training is because the external pressure required to absorb each reinforcement substance is different, the one-time process of reinforcement is simple but consumes precious energy, and the training is a long-term process, long but the strengthening conditions can be artificially made]

Thinking about the relationship, Xu Zhen chose to strengthen, this time the reinforcement is simple and unbelievable, 200 points of energy wander in the body, and the place where it flows is cool, sensitive, and feels the flow of air, a very vague but real feeling. Finally the energy flows into the heart again.

The strengthening of the connection twice made the heart beat faster, and in the quiet training room, Xu Zhen even heard an echo, it was really a powerful heart. As for the improvement in stamina, I can't see it for the time being, but from the results of scratching my skin with my fingernails, I can see that my skin is tougher, and I can't see the red marks at all. I don't know if it's a psychological factor, but I feel as if I've turned white.

Walking out of the training room, I feel that the world is so beautiful and my body is refreshed. I didn't expect that there were so many problems with my body that seemed to be okay in the past, but now that there are no problems, Xu Zhen even thought that it was impossible for him to be sick.

Drip, drip! Xu Zhen received a message from Zhao Bin, telling him to go to his room immediately and talk to him about something. Xu Zhen thought about it, Zhao Bin seems to have his own information, so he asked me to go because of this enhancement!

Feeling that a huge secret was about to be revealed in front of his eyes, Xu Zhen couldn't help but be a little excited.

After the game in the dormitory (only the dormitory area can log out of the game), get dressed, push open the door and hurriedly run to Zhao Bin's room, halfway through, Xu Zhen calmed down, he couldn't show such eagerness, he couldn't let them take the initiative, otherwise he could only be led away by them.

Adjusting his pace and breathing, Xu Zhen felt that he was in control of his body with ease, which was a bit similar to what he did in the game. I didn't think much about it, and I imagined the scene in my mind.

Knocked on the door three times, "Please come in." He pushed open the door and walked in. It's still the same table, but there is one more person, who looks like he is also middle-aged, sitting side by side with Zhao Bin.

"Please sit down, introduce yourself, my name is Bai Binghua, and I am also a mentor, we have all read your information." The middle-aged man said.

Seeing Xu Zhen sit down a little nervously, Zhao Bin said, "Don't be nervous, will you give you a chance to save the world?" "Don't do it, it's just a matter of leaving it to a professional to do such a dangerous thing as saving the world." Xu Zhen was a little flustered, but he immediately reacted that this matter was very dangerous, and opened his mouth to refuse.

"Giving you a superpower?" If you have superpowers, it seems easier to save the earth!

"Consider, consider."

"Sleeping in the same room with a beautiful woman."

"It's done."

After seeing Xu Zhen's agreement, he took out a contract and gave it to him. Xu Zhen took a closer look and found that there was a family insurance. Xu Zhen pointed to this clause and asked, what does this mean? Zhao Bin replied with an indecent face: "You are all big heroes who save the world, you can't let you still worry about the situation at home, and you can't save the world wholeheartedly!" Rest assured, we have the above background and will never let the hero's family suffer. ”

After signing the contract, Zhao Bin turned around and walked to the wall, and when he touched it, a door suddenly appeared on the wall. As he walked, he said, "Come in, let you see the truth of this world." ”

After entering, I found that there was a very high-tech room behind, everywhere with the naked eye was a small square without movement, constantly changing the shape of the combination, walking to the side, Zhao Bin waved his hand and the scene around changed, he and Xu Zhen appeared on a desolate land, looking into the distance, Xu Zhen was scared, the moon hanging on the edge of the sky was very big, and it was the same as the earth.

Seeing his surprised look, Zhao Bin said: "Don't think about it, that is the earth, the place where we are out now is called the 'Earth Frontline', and this is the only way for most alien creatures to invade the earth." ”

The field of vision moved rapidly, Xu Zhen saw a lot of monsters, not only a kind of bug, but also many monsters that were obviously not bugs, and soon a high wall appeared in front of him, and there were many people as small as ants behind them, and there were people standing on the wall, some monsters were attacking the high wall, and there were constantly cannonballs flying out of the high wall,
