As the energy circulation operated, the wonderful energy in the surrounding space began to slowly gather towards the qi circulation in Xu Ze's body, but while passing through the musculoskeletal, it was slowly strengthening the strength of these muscles and bone cells......

At this time, fine beads of sweat gradually began to appear on Xu Ze's forehead, and his handsome face, which was originally relaxed and casual, gradually began to be solemn.

At this time, in the energy circulation, the speed of the airflow was slowly slowing down, but Xu Ze was going all out to promote the airflow to continue to run.

At this time, Xu Ze has run eight laps smoothly, and at this time he is running on the level of the ninth lap, with the increase of the airflow lap speed, the energy contained in the airflow is getting more and more sufficient, so the slower it runs, and after running to the eighth lap, it will not be able to go up again to the middle of the back.

Xu Ze is now going to break the boundary of this boundary, and run the airflow over his head for a hundred meetings, as long as he passes a hundred meetings, it will be easy to make the ninth lap, and after a hundred meetings, he will directly descend and flow back into the sea of qi.

At this time, the energy airflow, under the full impetus of Xu Ze, was going up along the second vein of Rendu at a turtle speed, almost rising at a speed of less than ten millimeters per minute, and at this time, it was still at the big vertebral point in the neck from the top of the head.

The sweat on Xu Ze's forehead is getting thicker and thicker, beads of sweat the size of sesame seeds are thinly covering his white forehead, his thin lips are tightly pursed together, and his two handsome eyebrows are slightly wrinkled, and it can be seen that Xu Ze is working hard now.

Xu Ze himself was really struggling to support himself at this time, and the feeling of pushing a thousand catties was too hard, and almost every time he took a step forward, the resistance was much greater. However, he still did not have the slightest idea of giving up, Xu Ze was very grateful to Xiaodao and Bond for the training he had given him in this month, which made his willpower much stronger than before.

If it had been so hard in the past, his somewhat lazy surname would definitely make him decide to rest for a while and then try again next time.

Persistence is bound to be rewarded, Xu Ze now feels this very really, feeling the energy flow slowly under his own efforts, although the speed is very slow, but still moving forward, he can't help but cheer up: "It's fast, it's fast... It's only a short paragraph, and it's about to go to a hundred. ”

The sweat on his forehead began to slowly descend down his sideburns, but Xu Ze's face began to reveal a trace of excitement, but after knowing how long it took, it finally seemed to "pounce" with a soft sound, and at Xu Ze's insistence, the energy airflow instantly broke through Baihui, and then quickly flowed back from the forehead to the bottom, and the wonderful energy particles in the surrounding space fluctuated for a while, and then quickly swarmed in from Baihui at a speed several times the usual, merging into the energy airflow, making the energy airflow expand rapidly, and slowly hovered in the sea of qi.

Xu Ze was looking at the energy mass in his qi sea through his spiritual power in a daze at this time, watching it slowly circulate, and then expanding the qi sea step by step, I don't know how long it took before it slowly stopped.

At this moment, Xu Ze saw the sea of qi that had been more than doubled, and the huge energy mass gathered in the sea of qi, and was stunned, the difference in this circle turned out to be so big......

At this time, the knife in Xu Ze's body was also overjoyed by the swarming energy, and he was looking at a certain number and shouting: "25% 28% 30% 60% 83%!

The voice of the system's automatic response program also automatically sounded in Xu Ze's mind at this time: "The host has successfully established a first-level energy cycle, a first-level knowledge perfection, a f-level physique, and meets the promotion requirements, and the system will automatically upgrade and start ......."

"Tick... The system upgrade is completed, which takes 58 seconds, consumes 60% of the energy, connects to the host, and opens the first-level permissions. ”

With the sound of the system, Xu Ze instantly appeared in the virtual space of the system.

Looking at the obviously bright and spacious virtual space around him, Xu Ze couldn't suppress the excitement in his heart, and suddenly shouted loudly: "It's upgraded... After working for so long, I finally upgraded ......"

"It's so easy to be satisfied when you see this kid happy..."Xiaodao was on the side, looking at Xu Ze, who was excited like a child, touching his smooth chin, and shaking his head with an unfathomable face: "I wanted Tao Jun to be promoted to level six back then, but I wasn't so excited......

"Knife, hurry up and get all the permissions... Hurry up..."Xu Ze, who finally calmed down from the ecstasy, one thing was to run to the knife and reach out for permission, he had been looking forward to this for a long time, he wanted to know very much, such a powerful system, in addition to the functions he already knew, at the first level, what else was there?

Xiaodao blinked, looked at Xu Ze curiously, shrugged his shoulders and said, "The system has automatically granted you permission, what are you still asking me for permission." ”

"Uh... Permission given? Xu Ze was stunned for a moment, but he reacted quickly, grabbed the collar of the knife, shook it a few times, and said hatefully: "I have permission, but I don't know what my own authority is... Hurry up... Isn't it just for this day that I've worked so hard... If you don't say anything, I'll tear you down..."

Looking at Xu Ze, who was anxious and red-eyed, the knife laughed dryly twice, flashed, took out Xu Ze's palm, appeared two meters away, reached out and stroked the collar, and then reached out to block Xu Ze, who was about to come forward to pull the collar again, and said, "Okay... I'll show you, I'll show you... We're all Svens, so why bother... Why bother... Alas... The so-called gentleman does not move his mouth... Yes... No, the gentleman doesn't move his hands..."

At this time, due to the system upgrade, the running speed soared, and he was so excited that he was running the train with a knife, looking at Xu Ze at this time and began to roll his sleeves, it seemed that he was ready to start fighting, so he quickly stopped, waved his hand, and a light screen appeared in front of him, which stopped Xu Ze's anger.

Xu Ze stared at the rows of words displayed on the light screen, and gradually his face became exciting, and he was surprised and happy for a while......

Routine blood test... Urinalysis... Poop routine... Electrocardiogram... X-ray... Basic CPR ......

These are extremely basic, but also extremely commonly used things, compared to other things, Xu Ze is much more curious about this basic cardiopulmonary resuscitation, and after a closer look, he found that it can be used as an electric shock for the defibrillator when the patient is in cardiac arrest.

Moreover, this electric shock is not a mechanical shock, but a biological electric energy, which can directly activate biological cells and make the heart beat again. When Xu Ze saw this function, he couldn't help but sigh that it was too strong, now it's okay, with this thing, unless the patient is really bad enough to be saved, otherwise it will be a death on his hands in the future, but it is really not an easy thing.

But Xu Ze also discovered a new surprise, it turned out that the ring on his hand also had a lot of special effects.

You can go directly to the extreme to perform some tests, such as blood routine... Electrocardiogram... It's all extremely practical, and there's even a chicken rib function... The electric needle can be used to release lightning arcs of about 1,000 to 10,000 volts for attack, but each attack requires a lot of energy.

This function is indeed a good attack weapon for ordinary people, but in the eyes of Xu Da, who has an F-level physique and is initially proficient in future actual combat combat, it can only be regarded as a chicken rib, anyway, now ordinary three or five people are no problem for him, and he doesn't need to use this thing at all.

The voltage of this thing is not too high, and it also consumes electricity, and the original power consumption is nothing, but this electricity is accumulated by Xu Ze's own hard work......

PS: Thank you, the new book list has risen one place...... Hey
