The energy air mass slowly rose from the back of Xu Ze's neck, and a trace of coolness kept pouring in from the top of his head...

Xu Zewei closed his eyes and continued to promote the operation of the energy cycle, he felt okay today... There should be no problem...

As the energy air mass got closer and closer to the Baihui above his head, the excitement in Xu Ze's heart became stronger and stronger... A few minutes later, the energy air mass passed through the Baihui above his head smoothly, and in an instant, Xu Ze only felt that with the passage of the energy air mass, the place above the head Baihui was as if a hole had been opened, and a cool breath was poured in, accompanied by a huge amount of energy, from the Baihui acupoint towards the energy circulation...

The huge energy particles instantly lured into Xu Ze's Rendu second vein from Baihui, and filled Xu Ze's Rendu second vein full...

At this time, the large influx of hesitant energy particles, the energy air mass began to swell wildly, and then continued to further expand the sea of qi, circling in the middle...

Gradually, the sea of qi had expanded to a certain extent, and it was no longer able to expand, but at this time, the energy air mass was still expanding rapidly, until it was filled with this sea of qi.

It's just that at this time, those energy particles are still pouring in crazily, and the energy air mass is squeezed by these energy particles, and then it bursts violently, and a huge stream of biological energy rushes towards Xu Ze's body and limbs. "Huh" was shocked by these huge biological energies, and the whole body felt light, making Xu Ze exhale freely.

However, these huge biological energies continue to invade the cells of muscles, bones, and skin little by little, slowly staying and slowly strengthening these cells.

As these reinforcements progressed, Xu Ze only felt numb all over his body. Standing on the balcony, I couldn't help but take a few breaths before forcibly suppressing the feeling of tingling into my heart.

But fortunately, slowly the feeling of numbness gradually dissipated, and Xu Ze only felt that his whole body was refreshed at this time, as if he was full of infinite strength.

Suddenly, Xu Ze's voice suddenly sounded in his mind: "The host has successfully established a fifth-level energy cycle, the physique level meets the promotion requirements, and the system upgrade has begun..."

"Tick... The system upgrade was completed, it took sixty seconds, the energy consumption was forty-six percent, and the fifth-level authority was opened..."As the cold, but heavenly-like voice of No. 1 sounded, Xu Ze couldn't help but stand up suddenly, standing on this small cliff, facing the still hot mountain wind, and cheered loudly...

"Level five... Finally level five, -" Xu Ze cheered loudly a few times, but finally calmed down a little, and after taking two deep breaths, he finally said to No. 1: "No. 1, can I start waking up the knife now?" ”

"I'm sorry... Medical Officer Xu Ze, the energy is only fifty-four percent now, and it must be one hundred percent to try to wake up the main system... And the main system reboot time, it may be longer... When the system restarts, all system functions cannot be started, it is recommended to try it in a safe place. No. 1's answer made Xu Ze a little disappointed, but seeing that the time was not early, he had to temporarily put down the plan to wake up the knife and transfer it back to the Guo'an base, "Naturally, it is safe and clean there, and no one will disturb him...

After returning to the national security base and hurriedly picking up a few mouthfuls of food, Xu Ze returned to the barracks where he lived and practiced energy circulation, although the aura here was not as abundant as the small cliff, but it was not bad, enough for Xu Ze to accumulate the entire energy in a short period of time...

Although Xu Ze was very anxious about getting the system seriously injured as soon as possible and waking up the knife, Xu Ze was also very concerned about what new system functions could be opened after breaking through the fifth level, so before starting to cultivate the energy cycle, Xu Ze still asked No. 1 what he had gained now..."MRI, electrosurgical knife, air source disinfection, short-range wave light emission..."No. 1 mechanically reported to Xu Ze.

Magnetic resonance imaging Xu Ze has used it before, and it is not much different from the type of smack, and the electric knife, which is naturally the electric knife used in surgery, can prevent a lot of bleeding when cutting. As for air source disinfection and short-range laser emission, Xu Ze was a little confused...

Regarding Xu Ze's doubts, No. 1 explained very clearly that air source disinfection is mostly used for emergency operations in the field without disinfection equipment. Routine disinfection of the skin or wound can be carried out directly through air to complete surgery and debridement...

As for the short-range wave light emission, that is, the improved version of Xu Ze's small laser cutter, it has just become a close-range attack weapon that can shoot a laser with an effective range of fifteen meters, at least much farther than the attack distance of electric shock and laser cutting, and it can be regarded as the first shooting lethal weapon of the system.

Xu Ze is still very satisfied with these functions, it seems that the system is now more and more biased towards a real medical soldier, from electric knife to air source disinfection, it is all surgery, and even more suitable for emergency surgery in the field

And what really moved him was naturally the function of short-range wave light emission... This function seems to be very powerful, the first real non-melee weapon, which makes Xu Ze, who doesn't like close combat very much, very happy.

With this thing, it is equivalent to carrying a pistol with you, although the range is indeed a little closer, but its advantage is that it is silent, not easy to be detected, and has good penetration... It's really a must-have for home killing...

After a general understanding of the new functions opened by his system, Xu Ze settled down and began to cultivate the energy circulation, in order to wait for the restart of the system, as well as to wake up the knife, it is best to prepare.

For this day, Xu Ze has been looking forward to it for a long time, and he really misses that knife that is a little rappy, but extremely concerned and considerate...

As the energy cycle runs, the energy accumulation mark in the virtual space gradually begins to rise rapidly and slowly...

It took Xu Ze six hours to fill his energy, and under the call of No. 1, Xu Ze slowly stopped his cultivation, and ordered No. 1 with a little nervousness: "Restart the system... Wake up the main system! ”

"The countdown to the system reboot begins... Ten, nine, eight, seven..."With the countdown of No. 1, Xu Ze was a little nervous at this time, because No. 1 said a long time ago that there was only hope - to wake up the main system by restarting, but it was not for sure...

If he finally entered the third level, but there was still no way to wake up the knife, Xu Ze didn't know what to do... For the knife, his feelings are really deep, and he has always hoped that the knife can be awakened... If there was no knife, relying on the old-fashioned guy No. 1 alone, Xu Ze didn't know how much regret he would have. "Three, two, one... The system reboots Kaihime-" As the voice of the first sounded, and then suddenly it became silent...

Xu Ze knows very well that this process must be in the process of restarting the system again, and whether the main system can be restarted to wake up the knife in the end depends on the situation after the system is restarted.

Xu Ze felt that time was so sad for the first time, although he was very sure that the waiting time was only four or five minutes, but it felt like it was as long as half an hour...

Finally, in the silence, a faint murmur began to sound in my head, and then a voice came: "System reboot complete..."

Hearing this calm and somewhat mechanical voice, Xu Ze's heart suddenly felt cold, could it be one by one

Just when he couldn't suppress the disappointment in his heart, a familiar voice suddenly sounded in his mind: "Xu... It's been a long time since you've seen me, do you miss me? "Knives? Is the knife you? Hearing this slightly ridiculous familiar ping tone, Xu Ze was stunned for a moment, but a wave of ecstasy suddenly poured into his heart, and he began to shout excitedly.

The sound of the knife is still --d. The tone of ridicule in the past, as if this long slumber had nothing to do with him, just in a sighing tone, he shouted loudly: "Xu... I'm glad I haven't seen you for a few days, and you've advanced to level five... Sky... It's incredible..."

"It seems that I still occupy a small place in your heart, it really touches me so much..."Xu Ze was instantly pulled closer to the virtual space, and then saw the familiar handsome face on the opposite side, full of excited expressions similar to those of those low-level actors...

"You guy, I haven't seen you for so long, haven't you learned to be serious?" The realism of the virtual space is really high, Xu Ze touched his sour eyes, wiped the eyelids that seemed to be a little wet, and looked at Xiaodaodao with tears and laughter.

"Serious? Like that damn backup system? Xiaodao looked at Xu Ze with a mocking and strange expression, and said with a smile: "Xu... Aren't you tired of that wooden one? Got used to it? Forget it... Then I'd better go back to sleep and call that guy No. 1 out..."

"You damn it... It took me so much effort and so much risk to get you back..."Xu Ze glared, then looked at the knife in front of him, and said angrily: "You slept comfortably..."

"Alright, alright... Dear Xu, I miss you too..."Looking at Xu Ze's embarrassed expression, Xiaodao shook his head and sighed: "Look at this damn No. 1, what did he do for you?" Sky... Damn, it didn't stop you from endangering your own life... I'm going to have to reprogram it..."

"Oh... Damn, there are so many useless services out there, what surveillance unknown satellite phone is coming... Obviously, all the energy has been drained during this time, and there is no monitoring, and these tasks are still in the list for so long-deleted, deleted... It's all garbage, and people have already changed the machine number at this time. The knife cursed as he stored the system that had been messed up by the one.
