In the first interstellar era, with the development of science and technology, more and more people relied on technology and electronic equipment, and later it was the same for warfare, relying too much on high technology, so that they suffered a big loss in the war with other races, a large land war, and the imperial army was completely wiped out.

Since then, the empire has begun to pay attention to the development of the human body itself, and various body refining methods have appeared, among which the effect of relying on drugs to refine the body is the most prominent, and the time is also the shortest, and a batch of high-physique warriors can be created in batches in a short period of time.

But the side effects are also obvious, such fighters are very strong in combat effectiveness at the beginning, especially the ability to fight alone, but barely more than two years, there will be all kinds of problems in the body, and the decay is very rapid, so that many times later there were problems in this in the coordinated operation, and then the method of purely using medicine to improve physical fitness was abandoned.

It took the empire more than ten years to figure out the correct way to refine the body, which is to carry out high-intensity exercise with the assistance of drugs, which can quickly stimulate the body's potential.

This is a common method in the Empire, and there is another method called the Law of Internal Refining.

The dependence of the internal refining law on drugs is very small, and they are all divided into factions, not everyone has this opportunity to come into contact, and even most people do not know this method at all.

An Yunshan was also obtained by chance, and for this reason, she singled out three high-level Zerg without any hot weapons, and died nine times.

The principle of internal refining originated from qigong at the earliest, and in layman's terms, the principle of breaking a boulder in the chest also lies in this, lifting it in one breath can make a certain part of the body relatively hard, and when performing similar performances, it will not hurt the body.

To simply understand the law of internal refining is to use this method to improve physical function for a long time, continuously develop the potential of the body, and make the physical fitness improve as quickly as riding a spaceship, and there are no side effects!

An Yunshan came here, in addition to all kinds of abilities and experience as the king of individual soldiers, what was also valuable was the law of internal refining, which was probably the only way to quickly change her current situation.

She had to quickly recover her previous combat effectiveness, otherwise she would be very insecure in such an unfamiliar environment.

This is not the first time An Yunshan has practiced the law of internal refining, there is no sense of stagnation at all, as long as she can sweat successfully on the first night, she will be on the right track.

As soon as she concentrated on cultivating the Inner Refining Method, the pores of her body gradually opened, waiting for the sweat to drain out.

Sweating in the first two days will bring out a lot of moisture in the body, which can be said to be the source of the lesion, and many diseases are caused by moisture.

After the moisture is discharged, the qi in the body is generated, but the qi is very small, and I am afraid that it will not have much effect on the body, just like the thread of sewing clothes.

Qi is the core of the entire internal refining law, and it is also the core of developing the body's potential.

After three hours of practice, An Yunshan's whole body was soaked, as if he had just been fished out of the water, and although he had not yet reached the point of removing the residue stains in his body, he also had a faint smell on his body.

This made An Yunshan unbearable, which was the most important reason why she kept thinking about how to take a bath.

An Yunshan sat up and looked at the moonlight outside.

I can't say it, so I can only take a risk.
