In the early morning, the soft sunlight fills the courtyard of the Aoyagi family, and the melodious sound of birds occasionally sounds. It was the joyful call of the birds that had found breakfast.

"Ah~"

Sitting up from the bed, Aoyagi's eyebrows furrowed, his right hand covering his head, and his face wrinkled in pain. The head that was woken up by the alarm clock was still dizzy, and with the beating of the blood vessels, the Yin Hall seemed to be squeezed vigorously, and the pain hit one after another, stirring up the mind and the spirit was scattered.

After sitting on the bed for a long time, the sleepiness receded, the consciousness was clear, and the pain was slightly lessened, Aoyagi gently rubbed the stinging temples. The headache upset him, but he couldn't help but think of the experience of last night.

Last night, I should have entered my own mental space in my sleep.

The sore body reminded Aoyagi that the body that was in good condition last night was not real, and it should have been in the spiritual world at that time.

This may also explain why my head hurts so much when I wake up after finally fainting from exhaustion in space. Being tired and dizzy in the mental space means that the spirit is exhausted, and it may even be mentally damaged, which is not surprising, causing headaches.

In his previous life, Aoyagi sometimes lacked rest and was not in good spirits, and he also had headaches, but he finally got rid of it after a good night's sleep.

Alas, it seems that today can only rest.

Sure enough, if you don't do it, you can't die, and you have the illusion of adding a "I can break through the limit" in life.

Aoyagi was unwilling, but he understood that seizing the time to become strong did not mean that he was reckless regardless of his physical condition.

Last night's encounter also taught him a lesson, if you don't work hard according to your physical condition, you will not only fail to achieve the effect of exercise, but also may harm your body. Only by compressing the body can we break through the limit, but excessive compression is harmful.

Now that my spirit is somewhat damaged, it is appropriate to rest more and recover as soon as possible. In the case of headache and mental disability, the effect is poor, and it may also be injured due to the decrease in control of the body, and furthermore, it delays the recovery of the spirit, which is harmful and unprofitable.

Sighing, Aoyagi remembered his current situation, if only someone had taken care of him. My head hurts so much that I don't want to move at all. When you are sick alone, you have to take care of yourself.

Enduring the headache, Aoyagi washed up hastily and ate something casually. After eating, he sat on the bed for nearly half an hour, estimating that sleeping should not affect much at this time, and Aoyagi lay back on the bed.

Empty your head. Maybe it's psychological, but the pain is reduced when I'm in bed.

Although it was better, the pain lingered and hindered sleep. I don't know how long it took for Aoyagi to fall asleep in a daze.

…………

Compared with the transparent and shallow morning light, the afternoon sun is bright yellow, thicker and warmer.

Sitting on the bed and leaning on the pillow, Aoyagi opened the curtains and looked out the window at the courtyard in a daze.

After a long sleep, the headache has been greatly relieved, and only occasionally there is a slight stinging.

After the torture of headaches, I realized how precious the health I was accustomed to, and the pond water in this yard looked a little more colorful. When the surface of the pool is wrinkled by the breeze, there is also a smart charm. And the leaves of the trees look a little more tender than yesterday's.

I didn't eat much in the morning, slept until five o'clock in the afternoon, missed lunch, and Aoyagi's stomach was empty.

After enjoying the scenery for a while, Aoyagi's stomach screamed.

After slowly cleaning up, Aoyagi ate a bowl of soba noodles for dinner at a nearby shop.

When I got home, it was already dark. The dark night sky, twinkling with countless stars, standing in the courtyard and looking up for a while, Aoyagi couldn't find any constellations that he was familiar with in his previous life, but this is normal, they are not on the earth anymore, and it will be surprising to be able to find them.

Turning on the electric light and sitting at the desk in his bedroom, Aoyagi took out a pen and paper and prepared to clarify the important matters and make a practice plan, which he recorded in kanji.

After thinking about it, Aoyagi put the study of the characteristics of the spiritual space and how to use it at the top of the list. Establishing a clear practice plan and improving physical fitness are ranked second. As for the search for ninja-related knowledge, secret arts, etc., it is ranked third, although this matter is important, but now there is no clear way to obtain it, and it can only be fate.

After clarifying a few important things, Aoyagi recalled what he had learned last night and recorded it in a special notebook. Then, based on this knowledge, he began to develop a detailed exercise plan to try to get enough exercise and rest for each part of his body.

Since he only studied part of the materials last night, Aoyagi only made an initial version of the plan based on the materials he learned, and planned to continue to study hard in the space at night before revising the plan.

After all this, Aoyagi lay down in bed with anticipation, ready to enter the space again in her dreams.

He has fallen in love with learning and genuinely loves the feeling of being filled with knowledge. Knowledge and theory can guide him forward, and he no longer needs to blindly grope by himself, and this sense of security and steadfastness fascinates him deeply, which he has not experienced in his previous life for more than ten years of study. Sure enough, applying what you have learned can greatly stimulate people's motivation to learn.

However, he rested well at night, had no dreams and had no opportunity to learn.

Early in the morning, as soon as Aoyagi opened his eyes, he realized that something was wrong, and it was not the space that was shining everywhere, but the ceiling of his bedroom.

The head is completely painless and has returned to its normal state.

He sat on the bed and wondered why he hadn't entered the space this time.

Comparing the two days, the biggest difference is that I did a lot of high-intensity workouts the day before yesterday, while yesterday I didn't. Previously, Aoyagi had not done a high-intensity workout, and he had not entered the space. In this way, the presence or absence of high-intensity exercise is related to whether or not you can enter the space. Relevance is not the same as the cause, but it foreshadows that one of the parties may be the cause of the other.

So, it's a good idea to assume that high-intensity exercise is a necessity to open up space.

Aoyagi made a decision to continue exercising today to see if she could enter the mental space again. And this is exactly in line with the plan, using the exercise knowledge learned in reality, really digesting it, and turning it into your own.

As Aoyagi had predicted, after a long and hard workout during the day, he once again entered the mental space when he fell asleep at night.

And the mental space is the same as the last time I came in, there is no change.

Aoyagi, who was eager to learn, did not look at the space too much, he immediately walked to the bookshelf, picked up the books, sat cross-legged on the ground, and carefully read and memorized this precious knowledge. It wasn't until he was mentally exhausted and sleepy that he stopped reading and fell asleep on the floor of the space.
