More than a month ago, Uchiha You erased one day's memory of old man Xin Yin, but he did not use too much force, which left the old man with a vague impression of many things.

In order to thank the old man for his generous "gift", and also to confuse these strong or weak impressions over time, Uchiha You hinted to Shisui to bring the old man home often to sit, eat something good, and drink some good tea.

Later, the old man could have a bowl of medicinal porridge once a day, which was very beneficial to his body.

After more than a month of intensive research, Uchiha You was able to obtain a large number of bitter medicinal herbs. He weakened the bitter taste through the offsetting of medicinal properties, and added a large amount of honey to cook them into a delicious sweet soup, or added them to fish and mutton soup to make a fresh and salty meat porridge.

Rich and willful.

However, the amount of money spent was too much, and Uchiha You had to use Shisui's money to cover it up, otherwise his spending would be enough to attract the attention of the family and the village, and even lead to an in-depth investigation.

So he dragged Uchiha Shisui and old man Xin Yin together and tried his successful medicinal diet in different ways every day.

Sometimes the effect of the medicine is too strong. The old man feels warm all over and very satisfied after taking it, but he is still hot when it is time to go to bed. He ends up sweating all night and feels dry when he wakes up in the morning.

There is a kind of medicinal food that is full of Yang energy, which is extremely beneficial to old man Xin Yin, but it is not friendly to the child Shisui. The reason is that his body's related functions are not developed, and the medicinal power has nowhere to go. It can only rush to the top of the head, causing nosebleeds, which is very scary.

Even though he was occasionally frightened, Uchiha Shisui still liked medicinal food very much, because the difference between eating and not eating was too great. Even within one day, the results of hard training would be significantly different.

As a genius and a reserve ninja pursuing power, how could Uchiha Shisui give up such delicious and powerful food?

Miwa Masayo is another beneficiary of medicinal diet. In addition to the daily necessary intake of meat, her main energy intake has shifted to relying on medicinal diet to meet the huge energy needs of her body when practicing immortal arts.

The tabby cat no longer has to eat meat that is three or four times its own weight at a time as it did before. Imitating the owner's rapid digestion ability is itself a burden and consumption.

The huge burden needs to be digested slowly. In the past two months, Miwa Yashi has been doing nothing but eating and sleeping, and can only practice magic in dreams. This kind of life seems to be free and easy, but it is actually very boring. After all, cats are not pigs, and they have the need to play, move and hunt in their nature.

Being full is a mysterious feeling for the Cat Immortal. It is not determined by how many kilograms of rice or meat one eats. No matter how much of these ordinary foods one eats, one can only feel full but not satisfied.

In the past, after eating a whole pork leg, even with the rapid digestion method, my stomach would still hurt, but I would not feel full.

Now, all she needs is a bowl of thick porridge made with angelica, wolfberry, crucian carp and mutton eggs, and Miwa Masayo will feel physically and mentally satisfied, letting her know clearly that she is full.

After eating, he felt energetic. Sanlun Yashio greeted his owner, waved his paws to sprinkle a ball of fire, and jumped into the fire to go to the cat castle.

As the only cat fairy in the cat castle, she has to teach the kittens. It is a very interesting job and Miwa Masayo never gets tired of it.

By the time Uchiha You finished the bucket of porridge, lunch time was officially over.

Uchiha Shisui put on the weighted vest that Uchiha Yuu had modified for him, and practiced the traditional swordsmanship of the Uchiha family in the yard to strengthen his muscles and bones. Shisui, who weighed only 16 kilograms, was oppressed by the 80-kilogram weight, and his muscles and bones groaned, and his heart was forced to start beating at an accelerated rate.

It is in this state that the medicinal power of the medicated diet is fully stimulated, just like a flame rising from the lower abdomen, warming and nourishing the whole body, allowing the body to support the heavy pressure of the weight.

In this state of high load and high recovery, Uchiha Shisui's body was strengthened to the maximum extent. In just one month, his bone density, muscle toughness, and fascia elasticity surpassed all his peers, and even reached the physical condition of most Genin.

The foundation of a ninja is ninjutsu, the foundation of ninjutsu is chakra, and the foundation of chakra is spirit and body. Uchiha Shisui's chakra has experienced explosive growth since a few days ago.

The arduous weight-bearing training also made Uchiha Shisui mentally tough, strengthened his willpower and self-confidence, and enhanced his physical control. It can be said to be the best and most comprehensive training method.

But this is not a training that anyone can do. You must have enough nutrition to keep up. However, the nutritional demand is too great, far exceeding the limit of the human digestive system. Only a rich man like Shisui can supplement it through medicated food.

Shisui's tremendous progress was naturally noticed by the clan leaders and elders who were paying attention to him, and they also got Uchiha Yu's medicinal diet formula, which verified the powerful effect of the formula.

In Shisui and You's opinion, the only problem with medicinal diet is that it is too expensive and not widely available.

But in the eyes of the clan leader and elders, this is actually the biggest advantage, which can be used to widen the gap between the direct descendants and ordinary clan members, and ensure that their own bloodline can occupy the high position for a long time.

Uchiha Shisui just felt a little regretful, but Uchiha Shinin had a deeper concern. He asked Uchiha You: "If this continues, will there be a clan within the clan?"

Uchiha You smiled and shook his head: "If the current situation in the ninja world can remain unchanged for a hundred years, such a problem will indeed arise, but how is it possible?"

"The only thing that has remained unchanged for a hundred years is the Warring States period. That era has passed."

"In the era of the ninja village created by the first Hokage and Madara-senpai, there was only a difference between drastic changes and gentle changes, but the changes never stopped, and the speed of change was getting faster and faster. It was an era of change."

"It's impossible to maintain your position with just a recipe for medicinal food."

Of course, if the Otsutsuki family dispute breaks out as expected, and ends smoothly according to the script arranged by Otsutsuki Hagoromo, and enters a peaceful era under the deterrence of the two idiots, the matter will be hard to say.

Uchiha Shisui was not even five years old yet, and even though his physical fitness was already comparable to that of a Genin, he was still immature and had a lot of growth to do, so weight training could only be strictly limited to forty minutes.

As soon as the time was up, Uchiha You immediately called a halt, quickly helped Shisui take off the weights, and performed a full-body massage to smooth out the dislocations of muscles, tendons, and joints, and to prevent growth errors during the recovery of the medicine.

After repeatedly telling Shisui not to practice more after returning home, Uchiha You let him and the old man go home, and then he began his own standing training.

Uchiha You's training has now entered a critical period, and even simple standing still is not suitable to be shown to others.

After naturally transitioning from the Hunyuan Posture to the Mabu Posture, wisps of flames will appear around Uchiha You's body. They are high-density natural energy of fire attribute, surrounding the body to form a local high-energy external environment.

The external fire natural energy and the internal earth natural energy combine to jointly promote the evolution of the body during the foundation-building period.

If anyone saw this scene, anyone who was not a fool would know that there was something wrong with Uchiha You.

Would Uchiha Fugaku not bother him? Would Uchiha Setsuna let him go? And Shimura Danzo, would he not send people to monitor, assassinate and frame him?

How can Uchiha You stay in his little nest peacefully and practice comfortably?

In the evening, Miwa Masayo brought the latest information: the Third Kazekage was missing.

Uchiha You knew that his comfortable time at home was over.
