"Girl, you have practiced well in the past two days, and the teacher wants to teach you the internal strength of the heart method, this is the top heart method of our Medicine King Valley, you have to practice diligently in the future." The wind said lightly after the morning breathing and breathing lessons.

"Yes, Master, Zisu knows that he started late, but diligence can make up for his clumsiness, and he will definitely not disgrace Master." Zisu is also eager to try it in her heart, this kind of internal strength or something, is one of the things she is most interested in when she comes to this world.

Xiao Ai said that this kind of internal strength is to take the aura of heaven and earth, collect it for its own use, broaden the eight veins of the human body, and exert extraordinary combat power, which is not possible in modern civilization.

"Okay, for the teacher, I will teach you the mantra of practice, I will prepare the medicinal materials later, I will help you open up the meridians, the pills given to you during this time are not for nothing, they are all prepared for today, and we will start after breakfast."

The pill he gave Zisu was not only to regulate her uterine cold, but also to make her meridians more flexible and able to withstand more internal force.

At present, this kind of pill can only be refined by Feng Qingyang, and the medicines needed are all rare treasures, so it can be said that Zisu has eaten an unknown amount of silver unconsciously.

"Sister, you have to study hard with grandpa, if you don't learn well, be careful and I'll spank you when you come back!" When Zisu sent his younger brother out to school, Xiao Zikang instructed Zisu in his ear.

"Okay, I know, little housekeeper, I'll come back in the evening and make something to eat for you, Cang, take care of the young master." Zisu glanced at Cang, who was waiting at the door.

"Yes, master."

After sending Xiao Zikang away, Zisu officially began her first internal exercises, "The legs are open, the head is flat, the current vision, the mouth is slightly closed, and the breathing is adjusted." With chest, straight waist, abdomen, loose shoulders, the whole body is naturally relaxed. The wind raised lightly, and with a serious expression, he guided Zisu to the preparatory ceremony for the entrance.

Zisu relaxed his whole body according to the instructions of the internal strength mantra, and felt the changes in the dantian with the guidance of the wind.

In the words of the breezy wind, the cultivation of internal force is to seize the vitality of heaven and earth, and to melt one's own creation, we must let go wholeheartedly, accept the baptism of the vitality of heaven and earth, and turn into the internal force that exists in one's own body, so that it can be used freely, both offensive and defensive.

According to the guidance of the breeze, Zi Su easily felt a trace of cool vitality in the dantian, and according to his own consciousness, he traveled along the meridians and acupuncture points of the whole body.

The last little bit of cool vitality quietly existed in the Tianshu acupoint of his dantian, Zi Su closed his eyes and felt it, this feeling was very wonderful, that trace of cool vitality was now like a seed, lying quietly in the dantian, as if asleep.

"Well, your comprehension is good, your qualifications are good, although you are older, your sense of qi is still good, the seeds you can feel now are the foundation of your internal strength, and in the future, you will practice according to the internal strength and mental method I gave you, don't be lazy."

The corners of his mouth rose slightly, touched his snow-white beard, and looked at Zisu with satisfaction, although this closed disciple was a little late and missed the best period for cultivating internal strength, but with this sense of childishness alone, his internal strength cultivation in the future will not be too low.
