In the underground secret room, Sasuke opened his eyes and immediately checked the time.
"Is it really a fixed seven hours?"
Sasuke became more certain of his thoughts.
Only when it is observed will time begin to pass normally; if it is not observed, no matter how much time passes in other worlds, until Sasuke returns again, time will only pass exactly seven hours.
This is the case with Demon Slayer: Kimetsu no Yaiba, and it is also the case with the ninja world.
Therefore, his inference after the first time travel was wrong. If calculated according to the ratio of 300:1, even if each month has exactly 31 days, the total of three months would still be more than 3000 hours.
Of course, this is definitely better now. It is more beneficial to Sasuke to fix seven hours than to calculate it proportionally.
Because he cannot guarantee that he will not stay in a certain world for more than three months in the future. If he really wants to calculate it proportionally, he will probably disappear for many days at a time, which will lead to unexpected situations.
A fixed seven hours is good, just enough time to sleep for one night, and nothing will be delayed.
It was already dark outside, and Sasuke called the construction team to repair the damaged areas of his house.
No one came to ask him what happened last night, it was as if nothing happened, and there was no movement from either the ANBU or the police force.
Oh, I forgot, the police force is gone.
"Why can't this brain remember it?"
Sasuke patted his forehead with a smile on his face, but there was a hint of gloom in his eyes.
"Sarutobi, Danzo, Itachi, Obito..."
He would not let any one of these people go.
For the next few days, Sasuke temporarily stayed in his parents' bedroom.
His daily schedule is very full. He practices ninjutsu and sun breathing in the morning, and studies demon blood in the afternoon.
In order to study demon blood, he also bought a set of very high-end research equipment.
Having said this, I have to mention that the technological development of the ninja world is really good.
First of all, there is electricity in the ninja world. It is not the thunder escape used by ninjas, but serious electric energy that can enter thousands of households.
Not to mention the distance, there are countless telephone poles and wires in Konoha Village alone. Sasuke's family also uses electrical appliances, including TVs, refrigerators, washing machines, etc.
In terms of medical treatment, there are all kinds of medical equipment such as electrocardiographs.
Other technological products such as radios, computers, cameras, movie playback equipment, trains, engines, etc. have also appeared long ago.
There are also many high-tech weapons in the military, such as the Chakra Cannon of the Kingdom of Thunder, which is said to be able to directly shatter the moon. Another example is the weapons on the Shura Path in Pain's Six Paths. Sasuke doesn't think that Nagato made them by relying on his imagination. He doesn't have that ability.
In addition, in some lesser-known corners of the ninja world, there are also many black technologies.
For example, the Snow Country's chakra armor and large-scale illusion projector, especially the latter, are actually unfinished products of the environmental transformation machine. Once completed, it will be able to turn the snow and ice of the Snow Country into spring-like weather all year round, which is simply outrageous.
It can be said that the technology of the ninja world is not backward, and in many places it is even much more advanced than the technology of the earth in the previous life.
With these technological supports, Sasuke's research on ghost blood has been greatly accelerated.
He first took out the blood of special ghosts such as Nezuko, Muzan, and Tamayi Through an electron microscope, he could clearly see the differences between the three types of blood.
Then the extract of the Blue flower was added to the blood of Tamayo and Muzan respectively, and the two bloods gradually appeared to be similar to Nezuko.
In addition, he also drew his own blood and compared it, and found the similarities and differences between his own blood and the blood of three-point demons. The difference is normal. After all, people in the ninja world have 130 trillion body cells, three times as many as people in other worlds.
As for the similarities, Sasuke found that his blood had the same changes as the previous three.
Obviously, this is brought about by the blue flower.
"This thing is really unreasonable. Can it change the blood of anyone who eats it?"
Unfortunately, the experiment is still in the observation stage. The next step is for Sasuke to inject demon blood into animals to see what happens.
If the animal experiments are successful, he will try to conduct human experiments.
He has selected the test subjects. There are many death row prisoners in the Fire City Prison. Executing them will consume national resources. It is better to leave them to the waste and use them. It can also save the Fire Country a lot of money. The Daimyo should be grateful. You are right.
The practice of Ninjutsu is relatively step-by-step. Sasuke's current main goal is to learn all the Uchiha clan's signature fire escape.
In terms of breathing techniques, he planned to suspend the practice of Thunder Breathing and focus on Sun Breathing.
Like most Uchiha, Sasuke's chakra is born with the attribute of fire. He can directly learn and perform fire escape ninjutsu without having to learn attribute conversion.
As for the thunder attribute chakra, in his past life memory, he should have mastered it through Kakashi's guidance during the Chunin Examination.
It's just that now Sasuke has taken this step forward a lot, and successfully developed the thunder attribute chakra when he first entered Demon Slayer: Kimetsu no Yaiba. And because he could only come into contact with the breath of thunder at that time, he made deep cultivation in this aspect.
But if we really want to be honest, his talent for fire is actually even better.
Therefore, the Breath of Flame and the Breath of the Sun are more compatible with him. Considering that the Breath of Flame is equivalent to a weakened version of the Breath of the Sun, he chose to get it right in one step and directly strengthen the Breath of the Sun.
Changing the breathing method requires re-adaptation to the full concentration and normal practice. After all, the breathing rhythms are very different between different breathing methods.
Fortunately, with the foundation of learning Thunder Breath, Sun Breath progressed very quickly. In just five days, Sasuke successfully improved Sun Breath to the level of full concentration and regularity.
I have to say that Sun Breath is indeed very powerful.
As the ancestral breathing method, in the normal state, the strength of Sun Breathing is all-round, with no shortcomings in explosive power, speed, lethality, and body skills.
However, after the Breath of the Sun entered the normal state, when Sasuke observed his blood again, he found that there were new changes in his blood.
"Is it because of the sun's breath?"
Sasuke took a second blood sample and compared it with Nezuko again.
Sure enough, the two bloods had something new in common.
Could it be that resistance to sunlight has something to do with the breathing of the sun?
Although Nezuko has never learned Sun Breathing, her father can.
In the world of demon slayers, blood is a very magical carrier that can pass on the various powers of ancestors to the next generation.
Tanjiro's family has studied Kagura, the god of fire, for generations, and the power of the sun may have already been contained in their blood. This can also be seen from Nezuko's vampire technique.
Without the power of the sun, why would her demon technique be able to ignite blood? Why can this blood technique hurt other demon?
"The breath of the sun and the blue flower of the other side, I am afraid that only by having both together can one be truly immune to the sun."
The more Sasuke thought about it, the more likely it seemed.
He immediately took out more blood, and then took out part of Muzan's blood, divided it into many different groups, and conducted more controlled experiments.
