Before four o'clock in the morning, Yan heard the sound of squirming next door, and after a while, Xiaoxue and Dou'er were already boxing outside...

Although these two children have only learned Taijiquan and cannot be used as a normal foundation building method, they are still quite hard.

Yan sighed and followed out.

When the two children saw him, they couldn't help but stop.

This is a very complicated emotion, sending people under the fence, and not knowing Yan's character, every move is cautious, even if he is self-motivated, he is afraid that he will ruin the future because he disturbs Yan.

Yan was a little distressed to see it, he really didn't know what they had experienced before, like those cultivators he had met before, they were either confident or hardworking, and there was no one as timid as them.

"I'm angry!" Yan said.

"Master, Master..."Xiaoxue said timidly, "I pulled my pocket to practice..."

"I'm coming by myself..."Dou'er hurriedly said, "It's not about Senior Sister!"

"Shut up!" Although Yan was angry on the surface, he was still secretly happy in his heart.

He said lightly: "I should have said yesterday that the practice should be moderate, two hours a day is enough, why do you get up at four o'clock in the morning?"

It's not the Hokage here, the children in the Hokage are overtrained, and it doesn't matter if they leave a dark wound, it's just a big deal to burp a few years ago...

But it doesn't work here, your goal is immortality, what if you overtrain when you were a child and affect your physical development?

"Let's all go back to sleep!" Yan patted the shoulders of the two of them and said, "Just train according to the schedule I gave, you don't need to practice, if you really feel free, it's better to read more books..."

"Oh..."The two little ones nodded silently and went back to their room.

Yan put away his hand and began to calculate wildly in his mind.

He didn't pat the child on the shoulder for no reason, but through this means, he extended the vision of the Eye of the Origin to the two children.

After having a meal yesterday, these two children played Tai Chi several times, although it is not a perfect foundation boxing method, but it is also a boxing method that focuses on upper limbs and muscle exercises, and naturally has the effect of physical realm exercise.

And the result of this day's exercise is that less than one-fifth of the area of the arm and lower arm has been refined.

At this rate, it will take them about 140 days to train their whole body.

The amount of qi and blood required to train the muscle realm is about 8 times that of the skin realm, 6 times that of the bone realm, 4 times that of the marrow realm, and 4 times that of the blood realm...

In this way, as long as the two elementary schools complete the training of the perfect meat god realm, it will take 34 years...

In fact, the closer you get to the limit, the more difficult it becomes, for example, it may only take three months for a person to review from 0 to 80, but from 80 to 100, it will take three months.

So if you really want to quantify, it will take about 40 years to complete the training of a perfect flesh god realm.

Moreover, Yan uses their current qi and blood values to calculate, as the two children grow older, a large part of the qi and blood they absorb every day will be converted into nutrients for physical growth, which will also slow down the time for them to practice.

"It's no wonder that the foundation building fist methods of the major sects are not very complete..."Yan pondered.

For example, the Red Lotus Eclipse Palm, which is only about 60% of the perfect foundation building method, has been fully practiced, and it is estimated that it will take about ten years.

But Yan didn't want Xiaoxue and Dou'er to change to the ordinary foundation building method, it was very simple, if the master cultivated the perfect foundation, and the apprentice cultivated the ordinary foundation, then the gap between the master and the apprentice would become wider and wider, and in the later stage, these two apprentices might be useless...

It's like if you practice the Perfect Foundation Building Method for them, and because of the relationship between flesh and blood, the time consumed will be too long...

There's no way he's going to find a second Polar Eye Heavenly Monarch to pass on to the two of them...

Therefore, the final contradiction falls on the problem of too little blood intake every day!

"Aren't there exercises to increase the speed of digestion?" Yan recalled those exercises in the Library Pavilion, as if there were no such exercises.

The visceral realm increases the digestive capacity, but it is already the sixth level of the viscera realm, and by that time the most time-wasting period has passed.

The masters of the Great Wilderness discovered this problem, but their solution was to simplify the foundation building boxing method and try to exercise to the key parts...

As for the elixir that promotes digestion, there should be none, after all, the elixir is made of medicinal materials with abundant spiritual energy, and after eating, it is full of vitality, how can it help digestion.

"Master, please drink tea..."Xiao Xue timidly brought a small table and placed it next to Yan, they saw that Yan liked to sit on the stairs and drink tea during the day, but they remembered this way of arrangement.

"You go to bed first, don't worry about me, it's six o'clock, but you have to get up early!" Yan said.

"Hmm..."Xiaoxue nodded, secretly happy in her heart, they may have really met a good person...

Yan took a sip and then frowned, this elementary school doesn't know how to make tea...

However, it doesn't matter, anyway...

Well, tea...

Yan remembered all kinds of tea drinks in his previous life that shouted to help digestion through the stomach and intestines, tea drinks do not necessarily help digestion, but in his previous life, the scientific community did research on human digestion in depth.

The digestive system of the human body is mainly the stomach and small intestine, and Yan can feel that the blood qi is born from the position of the dantian, which they said (not that the small intestine is equal to the dantian, but the two organs are located in the same position).

Therefore, the small intestine is the key to converting food into blood gas, and to strengthen digestion, it is necessary to strengthen the probiotics on the small intestine!

But why didn't the scientific community discover the energy of blood qi in the previous life, Yan guessed, could it be that people in this world have a kind of bacteria in their bodies that can convert food into blood gas?

There are more than 500 kinds of probiotics in the human body, billions of which are probiotics, which are symbiotic with humans, enhance immunity, promote digestion, and even have an impact on the intellectual development of infants and young children.

This kind of example is not uncommon, such as the Force Knights in Star Wars, the reason why they can feel the Force is because the mitochondria in their bodies have mutated into Force fibers...

Yan sat down cross-legged again, meditated, and then the pupil power slowly spread to the small intestine, and then he felt that something was wrong...

He saw himself as useless, because the blood qi in his body was left to him by the inheritance, not from food, and since he accepted the inheritance, he hadn't eaten for nearly a year!

Yan was speechless for a while, then got up and went to the kitchen again, and began to cook, and when he was done, it was almost six o'clock.

Dinner for two kids!

"Master, aren't you going to eat?" Xiao Xue and Dou'er looked at their plates, and then looked at Yan who was sitting quietly next to them, and asked.

Yan shook his head: "I Bigu..."

He doesn't know if it's right for him to adhere to the various ideas of cultivators in the fantasy world, anyway, he can convince himself!

As he spoke, he stretched out two poems and pressed them on the shoulders of the two of them, and said, "You eat, I feel where the blood comes from!"

The pupil force slowly penetrated into the two small bodies, silently passing through various cells and organs, and finally came to the destination...

The human organ, magnified countless times, is simply a biological factory, with all kinds of complex cells performing their own duties, and countless cells running precisely, providing their own strength for this huge system.

However, these Yan had already seen it on him countless times, and he was not too surprised, as long as he paid attention to a kind of small dots of silver light in a world full of darkness...

"It's this kind of thing that gave birth to mysterious blood!" Yan amazed and narrowed his vision to the silver dot.

This thing looks like a mango, glowing with a silvery white light, and it is impossible to tell whether it is a living thing or a cell of the human body itself.

They attach to the lining of the small intestine, absorb the energy of food, which is called ATP in biology, and then convert it into a part of the blood that can be commanded and manipulated...

It is this kind of thing that constitutes the basis of the entire Great Wilderness cultivation, countless people have become immortals and Buddhas, and the biggest hero is actually this kind of thing?

Yan feels that he has discovered a big secret...
