The energy gas slowly moved up from Xu Ze's back neck, and a hint of coolness kept pouring into the top of his head...

Xu Zewei closed his eyes and continued to push the energy cycle. His feeling today is OK... There should be no problem...

As the energy gas mass became closer and closer to the Baihui place on the top of his head, Xu Ze's excitement became stronger and stronger... A few minutes later, the energy gas mass successfully passed through Baihui on the top of his head. In an instant, Xu Ze felt that as the energy gas mass passed, the Baihui place on the top of his head was like a hole was opened. A cool breath, accompanied by huge energy, suddenly poured into the energy cycle from the Baihui point towards the energy cycle...

The huge energy particles instantly poured into Xu Ze's Ren and Du meridians from Baihui, filling Xu Ze's Ren and Du meridians...

At this time, a large number of hesitant energy particles poured in, and the energy gas mass began to surge wildly, and then continued to further expand the sea of ​​qi, hovering in the middle...

Gradually, the Qi Sea had expanded to a certain level and could no longer continue to expand. However, the energy gas mass was still expanding rapidly until it filled the Qi Sea.

But at this moment, those energy particles still poured in frantically. The energy gas mass was squeezed by these energy particles, and then suddenly burst out. Huge streams of biological energy rushed towards Xu Ze's limbs.

"Hu" was impacted by these huge biological energy, and his whole body felt light and fluttering, making Xu Ze breathe a long sigh of relief.

However, these huge biological energy continues to invade muscles, bones and skin cells one by one, slowly staying and slowly strengthening these cells.

As these strengthening progressed, Xu Ze felt his whole body numb. Standing on the balcony, he couldn't help but breathe a few breaths before forcibly suppressing the numbness into his heart.

Fortunately, the numb feeling gradually dissipated, and Xu Ze only felt refreshed at this moment, as if full of infinite power.

Suddenly, Xu Ze's voice that he had expected suddenly sounded in his mind: "The host successfully established a level five energy cycle, his physical fitness level B meets the promotion requirements, and the system upgrade begins..."

"Beep... The system has been upgraded, it took 60 seconds, and the energy consumption is 46%, and the level 5 permission is activated..." As the sound of No. 1's cold but natural sound sounded, Xu Ze couldn't help laughing and stood up suddenly, standing on this small cliff, cheering loudly against the still hot mountain wind...

"Level 5... Finally, level 5..." After cheering loudly for several times, Xu Ze finally calmed down a little. After taking two deep breaths, he finally said to No. 1: "No. 1, can you start to awaken the little knife now?"

"Sorry... Medical Officer Xu Ze, the energy is only 54%, and it must be 100% before he can try to wake up the main system... And the restart time of the main system may be long... When the system restarts, all system functions cannot be started. It is recommended to try it in the safe place." No. 1's answer made Xu Ze a little disappointed, but seeing that it was getting late, he had to temporarily put down the plan to wake up Xiaodao and return to the National Security Base...

It is naturally safe and pure there, and no one will disturb you...

After returning to the Guoan Base and hurriedly ate a few bites of rice, Xu Ze returned to the barracks where he lived and practiced energy circulation. Although the spiritual energy here is not as abundant as that of the small cliff, it is quite good, enough to allow Xu Ze to accumulate the entire energy in a short period of time...

Although Xu Ze was very anxious about restarting the system as soon as possible and awakening the knife, Xu Ze was also very concerned about what new system functions could be activated after breaking through level 5. So before starting the energy cycle, Xu Ze still asked No. 1 what he had obtained now...

"Nmature resonance imaging, electric knife, air source disinfection, short-range laser emission..." No. 1 reported mechanically to Xu Ze.

Xu Ze has used MRI to go beyond the level before, and it is not much different from the type of CT. Electrical surgery is naturally an electric knife used in surgical operations, which can prevent large amounts of bleeding during cutting.

As for air source disinfection and short-range laser emission, Xu Ze is a little confused...

Regarding Xu Ze's doubts, No. 1 explained it very clearly. Air source disinfection is mostly used for emergency operations in the field without disinfection equipment. The skin or wound can be regularly disinfected directly through the air to complete the surgery and debridement...

As for short-range laser emission, which is the improved version of Xu Ze's small laser cutter, it has only become a close-range attack weapon that can shoot a laser with an effective range of fifteen meters. It is at least much further than the attack distance of electric shock and laser cutting, and it is also the system's first shooting-type killer weapon.

Xu Ze was still very satisfied with these functions. It seems that the system is becoming more and more inclined to a real medical soldier. From electrocution to air source disinfection, it is all surgical procedures, and it is even more suitable for emergency operations in the field...

What really touched him was naturally the short-range laser emission function... This function seemed very powerful, the first real non-melee weapon, which made Xu Ze, who didn't like close combat, very happy.

With this thing, it's like carrying a pistol with you. Although the range is indeed a little closer, its advantage is that it is silent, not easy to be discovered, and has good penetration performance... It is really a must-have product for killing people at home...

In addition to having a rough understanding of the new functions enabled by his system, Xu Ze then calmed down and began to practice energy cycles. It is best to prepare for restarting the system and awakening the knife.

For this day, Xu Ze has been looking forward to it for a long time. He missed Xiaodao, who was a little raving but very caring and considerate...

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

It took Xu Ze six hours to fill up his energy. After No. 1's call, Xu Ze slowly stopped practicing and ordered No. 1 with a little nervousness: "Restart the system... wake up the main system!"

"The countdown starts with the countdown of the system restart... Ten, Nine, Eight, Seven..." With the countdown of No. 1, Xu Ze couldn't help but feel a little nervous at this time, because No. 1 said a long time ago that there is only hope to wake up the main system by restarting, but it is not certain...

If he had finally entered level 5 but still couldn't wake up Xiaodao, Xu Ze didn't know what to do... His feelings for Xiaodao were really deep, and he always hoped that Xiaodao could be awakened... If Xiaodao hadn't been Xiaodao, Xu Ze wouldn't know how regretful it would be to rely on the old-fashioned guy No. 1 alone.

"Three, two, one... the system restart begins..." As the sound of No. 1 sounded, it suddenly became silent...

Xu Ze knew very well that this process must be the system restarting again. Whether the main system can be restarted and the Xiaodao can be awakened depends on the return after the system restarts.

Xu Ze felt that time was so sad for the first time. Although he was sure that the waiting time was only four or five minutes, it felt as if it had been more than half an hour...

Finally, in the silence, a little noise began to sound in my mind, and then a sound came: "The system has been restarted..."

Hearing this calm and somewhat mechanical voice, Xu Ze's heart suddenly felt cold. Could it be...

Just when he couldn't suppress the disappointment in his heart, a familiar voice suddenly sounded in his mind: "Xu... I think you haven't seen me for a long time. Do you miss me?"

"Xiaodao? Is Xiaodao you?" After hearing this familiar voice with a little teasing, Xu Ze was stunned, a ecstasy suddenly surged into his heart and began to scream excitedly.

Xiaodao's voice was still full of teasing tone as usual, as if this long sleep had nothing to do with him. He just shouted loudly in an exclamation tone: "Xu...is very happy. You have not seen you for just a few days, and you have advanced to level 5... God... It's really incredible..."

"It seems that I still occupy a certain position in your mind. It really touched me..." 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 low-level actors...

"You guy, you guy, haven't you learned to be more serious for so long?" The imitation of the virtual space is too high. Xu Ze touched his sour eyes and rubbed his eyelids that seemed to have some moisture. He wanted to cry and laugh.

"Be serious? Like that damn backup system?" Xiaodao looked at Xu Ze with a joking and weird look, and said with a laugh: "Xu...Aren't you tired of that wooden No. 1? Are you used to it? Then forget it... Then I'd better continue to sleep and call out that guy No. 1..."

"You damn... I took so much effort and took so many risks to get you back..." Xu Ze glared at the eyes, then looked at the little knife in front of him, and said shyly: "You are sleeping comfortably..."

"Okay... Dear Xu, I miss you too..." Looking at Xu Ze's embarrassed and angry expression, Xiaodao shook his head and sighed: "Look at this damn number one, what did you do for you? God... Damn it, it didn't stop you from endangering your life... I must reset its program..."
