After passing through several tight checkpoints in a row, Chu Yi arrived at the fourth layer of the space in the city wall.

Compared to the low height of the upper two floors, the bottom fourth Zeng is quite empty, and the height has reached the height of a normal room.

The fourth floor of the entire space is composed of three areas, the dormitory area, the arsenal, and the martial arts training ground, and the martial arts training ground occupies more than one-third of the entire space in the whole room, and several well-equipped martial arts training grounds are distributed throughout the city wall.

According to the regulations on rotation, from six o'clock in the morning to six o'clock in the afternoon, these twelve hours are the time period for each department to take turns to rest.

Of course, six hours of rest is far from enough for such a high-intensity combat readiness situation, so they are generally on duty at night, and if the situation allows, some personnel can rest on the spot at their combat posts.

Under such regulations, the daytime rest time is undoubtedly precious, but under such circumstances, the entire daytime martial arts training ground is still overcrowded.

Without disturbing these cultivators, Chu Yi found a vacant place and began his own cultivation.

Breaking through from a martial apprentice to a martial artist, the cultivation method changes accordingly.

The thirty-six body refining methods combined with the breathing method constitute the cultivation method of the martial arts realm.

Martial arts muscle training, that is, a cultivation of the human epidermal muscles, through the movement of the body refining method and the coordination of breathing, exercise to improve the strength and vitality of the human body's epidermal muscles.

Martial arts cultivation is a process of transformation and evolution of the human body.

As the action continued, the energy on the skill panel dropped rapidly, and Chu Yi could clearly perceive the heat flow constantly washing over the muscle epidermis of the body, slowly increasing the strength and vitality of the muscle epidermis.

Judging from the current situation alone, no one knows how strong the martial arts realms are in those last few realms, and it is even difficult to simulate them.

When creatures from different time and space enter the Blue Star, they will be inexplicably suppressed, and how much of this suppression has not yet been studied.

But one thing is also clear, the stronger the cultivation power, the greater the suppression.

It's like a barbarian powerhouse that ravages at night, just when its cultivation power is suppressed, it shows a power like a god and a demon, and it is hard to imagine how terrifying it would be if it was in its heyday.

After a round of cultivation, Chu Yi habitually glanced at the skill panel.

Bow & Arrow: Xiaocheng (865/10000)

Knife Technique: Xiaocheng (2232/10000)

Refining Breathing Method: Refining Muscles (53/5000)

Terran Warbody: Beginner (19/1000)

Energy: 208

In the past few days, although a few barbarians have been killed, the speed of energy growth is far from keeping up with the speed of consumption.

Cultivation has reached the present, and a single cultivation can easily consume nearly 100 energies, and the acquisition of energy, in this special period, is not too difficult to say, nor is it easy.

At least before the large-scale invasion of the barbarians, it was still difficult to have enough energy to cultivate.

His eyes were withdrawn from the skill panel, and while thinking in his heart, the bone knife was already in his hand, and after looking at the bone knife in his hand, Chu Yi couldn't help but shake his head.

This bone knife, which was quite difficult to obtain at the beginning, has now been completely unable to keep up with its own development, and it can be regarded as being eliminated when it is obtained.

Although the bone knife weighs more than 100 catties, in terms of its current strength, it is still too light and light, and it is difficult to exert all its strength.

But fortunately, the tenacity of the bone knife is not bad, and it can barely be used. And for now, the opportunity for hand-to-hand combat seems to be difficult to appear.

The fingers lightly swiped the blade, and every move of the knife technique began to flicker in his mind, and the knife technique took off, and when he was about to practice, a hurried footstep came into Chu Yi's ears.

"Xiao Song!"

However, in an instant, Chu Yi judged the identity of the person who came just from the footsteps, the bone knife was sheathed, and Chu Yi turned to look at the figure that was rushing towards him.

"Commander. ”

After saluting, Xiao Song said what he meant,

"Regiment leader, there are people from the logistics of the mountain base, and there is a batch of materials that you need to sign for in person. ”

"Need me to sign for it?"

Hearing Xiao Song's words, Chu Yi was stunned, since entering the state of war, the original cumbersome rules have long been simplified to the point that they can no longer be simplified, equipment and supplies have always been connected to each other by logistics, and then reported to themselves after receiving them.

Even if it was the distribution of new equipment some time ago, there was never a situation where you had to sign for it yourself.

"Let's go, let's see. ”

Since the logistics of the base has put forward this request, it is natural that it has been considered, and it will be known by looking at it yourself.

......

Walking to the bottom of the city wall, Chu Yi saw dozens of armored transport vehicles parked on the side of the road, and beside the convoy, there were hundreds of heavily armed officers and soldiers guarding them.

Seeing this scene, Chu Yi was a little curious in his heart, here, this place where the army gathered, and such a heavily guarded guard, it can be imagined how important the things they escort are.

After being inspected by the vigilant soldiers, Chu Yi walked into the convoy, and at this time, next to a command car, several officers also walked towards Chu Yi.

"I'm Chu Yi. ”

After saluting, Chu Yi reported his name.

"Please show your ID. ”

One of the colonels replied with neither humility nor arrogance.

Hearing the officer's reply, Chu Yi couldn't help frowning, but he still took out his military ID card again and handed it to the officer.

After receiving the document handed over by Chu Yi, the colonel officer carefully observed the document before returning it to Chu Yi.

"Hello Commander Chu, I am Chu Wenfeng, a researcher of the Strategic Missile Forces. ”

"It was the task just now, and I ask for your forgiveness from Head Chu. ”

After confirming the documents, Chu Wenfeng's tense expression eased.

"Strategic Missile Forces!"

Hearing these words, Chu Yi's heart suddenly jumped, and his eyes couldn't help but turn to the armored convoy behind him.

It seemed that seeing Chu Yi's gaze change, Chu Wenfeng's voice sounded again.

"Commander Chu, here is the list of materials, please check and sign for it. ”

Taking the folder handed by Chu Wenfeng, Chu Yi focused his eyes on the document in his hand.

500,000 F-grade Blue Ying cultivation potions.

The first line of words that caught his eye made Chu Yi's heart tremble, cultivation elixirs, from the brute beast blood elixir at the beginning, to the later system standardization, evolved into several kinds of cultivation elixirs.

There is no doubt that the effect of the beast blood elixir is the best, and it is classified as an E-level cultivation potion, while the F-level Blue Ying cultivation elixir is an elixir developed by the research institute itself according to the cultivation of the body refining method.

It is said that the raw materials of this medicine are all kinds of Chinese herbs, which are refined and proportioned, and the color is also strange blue, so it is ordered to be called Lan Ying.

It's just that the effect is much worse than the beast blood elixir, so it is classified as an F-level cultivation potion.
