As the days passed, kukas spent most of his time digging a cave in this cave and then cultivating his fighting spirit and body. In just six or seven days, he felt that his strength had improved significantly. Of course, during this period, he also received a large number of materials provided by the military headquarters, many of which were for doctors.

The strength of this rapid improvement is entirely due to the female doctor and the drugs she makes. Of course, this is also inseparable from kukas\' hard cultivation. If kukas does not practice hard, even if the female doctor provides him with more drugs, his strength will not increase much.

On this day, kukas dug out the cave needed by the doctors, and a cave covering at least one mu appeared in front of the people. The doctors who got the news quickly came to check it, and then looked very satisfied. In their opinion, as long as there is enough space, they can plan the laboratory structure they want only with some boards. After all, they are only studying some drugs, not cultivating morale, so they won\'t ask how strong the laboratory is.

"This is a kind of exercise method that we specially modified for you according to your body. HMM! The effect is much better than what you used before." the old doctor looked very satisfied after inspecting their cave, so he took a scroll out of his arms and handed it to kukas. "It\'s just that this kind of exercise method brings you more and greater pain."

"If you want to be strong, it\'s normal to pay some." kukas was a little stunned, then took the scroll and said with a smile: "is it because my work has not been completed, you won\'t give it to me?"

"Of course not. You know, the deduction of this cultivation method is extremely time-consuming. We can push a set of methods for you in just a few days. It\'s great luck. How can you ask for more?" the old doctor said to kukas in his usual calm tone. Of course, later, when kukas practiced this secret method at night, she was seen by the female doctor. According to the female doctors, his cultivation method was deduced by doctors a long time ago, but it did not spread to ordinary professionals, but was controlled by senior officials of the military headquarters.

At the request of the doctors, kukas exchanged his surplus military skills for many materials, including heavy wooden boards, wide wooden beds, wooden doors, specially treated animal skin blankets, and a large amount of paper and pen and ink. Of course, he got more green ointment and some special drugs from doctors.

Those green ointments are of great help to his cultivation, and those special drugs he will use in the future. Any of them is very precious. Like those green ointments, there is no such thing in the military headquarters, or there is, but they are hidden by the military headquarters and never distributed to ordinary soldiers like kukas.

After receiving the new cultivation secret method provided by the old doctor, kukas couldn\'t wait to try to practice after dealing with some things about the miners.

In fact, this new cultivation secret method is very similar to the first one, except that one can only mobilize a small muscle to beat, while the other can mobilize dozens of muscles to beat at the same time.

A layer of ointment was applied to his body, accompanied by a large number of muscle beats, and they quickly integrated into his body. The integration of these ointments alleviated the pain caused by the violent beating of his muscles, but if ordinary people feel it, they will still feel extremely painful. But kukas is used to it now.

Kukas was practicing, while the female doctor took a magic timer and pen, ink, paper and inkstone and stood beside him to observe carefully. After counting the progress of kukas\' cultivation, apply more or less ointment to him, so as to make the best use of those precious ointment, so as not to waste the efficacy of these ointment.

While practicing in kukas, the door was knocked. Kukas exchanged military merit for this door. For privacy, he customized many wooden doors in the military headquarters to place them at each hole, thus replacing the extremely simple curtain and bell.

"Come in!" kukas answered in a rough voice after his muscles beat violently and absorbed the ointment completely.

"Sir, there is a steward of a chamber of commerce outside who wants to see you." the message was sent by a guard of kukas. The guard had been saved by kukas on the battlefield, so he was very loyal to kukas and served as the leader of all the guards.

"Let him in after a moment of magic." kukas was a little stunned. He didn\'t know what the people of the chamber of Commerce wanted him to do. You know, he has never been out since he arrived at the mine. If there is anything, he also gives it to his soldiers.

"Yes." the guard answered kukas\'s orders firmly.

When the door closed, kukas was not in the mood to practice. After wiping his body, he put on his officer\'s clothes and sat in his chair waiting silently. And the female doctor looked through her records.

"Knight, from tomorrow, our experiment will begin. At that time, I can\'t help you practice better." the young female doctor went to kukas and whispered after sorting out the documents in her hand.

"Ha ha! Your experiment is not carried out all day. There is always leisure time! I\'ll find you or you\'ll find me, and then continue to help me practice." kukas was a little stunned, and then laughed loudly. He couldn\'t accept the sudden words of the female doctor, so he wanted to continue the current relationship in this way.

"It\'s impossible. At the beginning of the experiment, I didn\'t know when I would have free time." the female doctor smiled. "But don\'t worry. I\'ll come to you every time and give you some advice on applying drugs."

"Your lab has been set up? I mean it will be set up in less than half a day?" kukas asked, scratching his bare head.

"Yes, because your men help. You know, they are very willing to help the doctor." the female doctor closed the golden curl in her ear and said with a smile: "they have great strength, and some of them are dexterous, so the arrangement is very smooth. You don\'t have to worry about that."
