Becoming a Demon King from Inuyasha

"I don't know much about the Yin-Yang master's talismans, but I can forge a seal that can swallow the talisman and then engrave it exactly as it was."

"It's actually possible to do this? Are there any requirements for the user?"

"No requirements, demonic power or spiritual power is fine."

“How long can it be used?”

"Not to mention decades, a few years shouldn't be a problem."

"How many talismans can one seal swallow?"

“It can be replaced at any time.”

With every sentence he heard, Hanakaiin Hidemoto's eyes would brighten a little.

Although it also consumes spiritual power, drawing talismans mainly consumes energy. Even an onmyoji who is an expert in this field must concentrate fully. If the talismans are drawn slightly crookedly, all the previous efforts will be wasted.

If there really is a seal, the cost of talismans will be greatly reduced.

If nothing else, it can at least solve the instant messaging problem in the Warring States Period.

However, there is still a problem.

"Mr. Yemen, the rune address book uses the same rune design. It can only be one-to-one, and it can't locate an individual like a mobile phone."

"If you want to talk to someone in private, you have to change the details of the rune. But then, every time you make a rune address book, you need to draw a new rune, which brings us back to the previous difficulty."

"Therefore, the telephone method is not advisable. We can only adopt a unified design and make it into a forum model."

"And if you want one-to-many, you have to create a relay station to receive the information, which is the server."

"Aren't you from an ancient time? How come you know about servers?" Ye Men couldn't help but ask.

"Before coming here, I made up some homework."

"Only one day and two nights? You learn really fast."

Ye Men exclaimed in praise, then turned to look at Dao Daosai:

“Can the server be built?”

Dao Daosai pondered for a moment, and said while thinking:

"I don't know what server you are talking about. If it is to intercept the rune information, it is completely impossible. But it is not a problem to copy the rune information and save it for everyone holding the rune book to see, and then clean up the information regularly."

"That's enough." Hanakaiin Hidemoto nodded slightly. "Then there's the eraser. Is there a way to make an eraser that can erase the rune information on the front without affecting the effect of the rune on the back?"

"I need to see what the rune address book you mentioned looks like first."

"No problem, Ye Men-kun, take out your book as well."

"it is good."

Ye Men took out the rune address book and rune pen from his waist pocket and placed them on the table together with Hanakaiin Hidemoto's.

"It's a good design. If you write on one talisman, it will be displayed on the other talisman at the same time, thus achieving the effect of long-distance communication."

"Unfortunately, the cost is too high and it can only be used on a small scale. Once the phone is developed, it will just be stored in the warehouse. Is there any way to improve it?"

"I don't know much about paper, and the talisman itself is nothing special. I can only think of a solution from the pen. How about improving the ink so that it can only be manifested for a period of time?"

"That's a good idea..."

Seeing that Tousai and Hanakaiin Hidemoto were discussing more and more seriously, Kagome couldn't help but lean over to Yemen's ear and whispered:

"After all, only a few people have spiritual powers. Even if these ideas can be realized, they can't replace phones and computers, right?"

"It's just a concept at the moment. If rune technology can really be developed, we can find a way to make a spiritual power version of the battery..."

Before Ye Men finished speaking, Hua Kaiyuan Xiuyuan raised his voice a little:

"Yes, batteries are also essential."

"If we can develop a spiritual power storage device, we can input spiritual power into it and store it during normal times, and then extract it when fighting."

"If we can add spiritual power conversion and purification devices, we can collect a large amount of spiritual power from monsters and humans."

"The so-called Four Soul Jade is nothing more than an energy crystallization of a large amount of energy gathered together. If we have a spiritual energy storage device, we can completely artificially create countless Four Soul Jades."

Ye Men burst out laughing. He just wanted to make a battery, but he actually thought of the Evil Emperor's relics, the Yin Seal, and the Four Souls Jade.

"Can it be done?"

Seeing that both of them were staring at him, Toudaosai scratched his head.

"It's not difficult to just store spiritual power or demonic power and transform it. But the problem is, what materials to use? Any material has a storage limit."

"If we use the bones of a monster, the storage limit should be the moment when it was the strongest in life."

"that's true."

Hanakaiin Hidemoto calmed down instantly. It was normal to have a storage limit, but in this case, the value would be greatly reduced, and he could only make a battery.

After all, every first-rate Onmyoji's spiritual power reserves are not low, so if it's just doubled or tripled, it won't make much sense.

Only when it is multiplied dozens of times and one can use at will those spells that consume several times the spiritual power to increase the power, will it have practical value.

Having said that, spiritual energy storage devices are still very important.

"By the way, I have something that needs to be improved. This is a storage talisman we developed. It can store a large number of items, but it can only be used once. Can it be improved to be used infinitely?"

"Let me see if you can use it."

"no problem."

Hanakaiin Hidemoto immediately demonstrated it on the spot, chanted a spell to put away the table, and then released it, and the talisman immediately turned into ashes.

Seeing this, Dao Dao Zhai was thoughtful:

"I can create a storage bag and incorporate the runes into it, and the effect will be just like you said."

"How long will it last?"

"If it's not damaged intentionally, it can be used for at least a few decades."

Hua Kaiyuan Xiuyuan's eyes lit up. Having a storage magic weapon was something everyone had dreamed of.

After all, who likes to carry a lot of bags when traveling?

Why don't you use the storage magic weapon? Is it because you don't like it?

No, it's purely because this thing only exists in myths and legends.

Even if it really exists in reality, it is a priceless treasure.

"Mr. Dao Daosai, let's start turning our ideas into reality. What materials do you need?"

"For the seal, special wood is needed. If possible, please allow me to get it from the Tree of Ages."

"no problem."

"For servers, we can actually use the Age Tree as well."

"no problem."

"As for the storage bag, the Tree of Ages..."

"no problem."

Seeing this, Kagome unconsciously interrupted:

"Sorry to interrupt, I have no objection to breaking off a few branches. Pruning branches is a normal thing."

"But according to what you said, I feel like the sacred tree is about to become a bare wooden stump."

"What is the Imperial Sacred Tree? We are talking about the Tree of Ages," Toudaisai asked in confusion.

"The sacred tree is what the Tree of Ages will be called five hundred years from now." Yemen explained, "By the way, in the world five hundred years from now, the sacred tree is the private property of the Higurashi Shrine, and Kagome owns it."

"How many branches do you need? Don't cut them into stakes."

"Although we rely on the Bone-Eating Well to travel through time and space, the power of the Bone-Eating Well comes from the Tree of Time."

"Although the Time Tree has only a vague consciousness, if we really make it angry, we may not be able to go back."

So that's how it is. Is the Tree of Time the key to traveling through time and space?

Dao Daosai thought for a moment, then said:

"If you don't use the Age Tree as the main ingredient but as a supplementary ingredient, you won't need too many branches. The seal and the server will require two branches, and the storage bag will require half or one-third of a branch."

Hua Kaiyuan Xiuyuan thought about it in his mind and spoke slowly:

"In that case, cut four branches."

"Two are used to make seals and servers, and two are used to make storage bags. Yato-kun, Kagome, and Yuura-chan will each get one, and the remaining one will be used exclusively for transporting military supplies."

"In order to avoid the hatred of the Tree of Ages, hold a sacrificial ceremony before cutting down the branches."

"Ms. Kagome, do you think this is okay?"

Kagome hesitated for a moment and nodded slightly:

"If it's just four, I don't have any problem with it, but... I'm a little worried about the opinion of the Imperial Divine Tree. It would be troublesome if I really can't go back."

"Then we can hold a spirit-inquiring ceremony during the sacrifice. If the Tree of Time has no objection, we can cut the branches."

"Ah."

Seeing this, Hanakaiin Hidemoto showed a slight smile on his face.

He actually didn't take what Ye Men said about the resentment of the Tree of Time seriously.

It's just four branches. If it is really so stingy that it doesn't allow itself and others to go back, just cut it off and ask Dao Daosai to turn it into a device that can travel through time and space.

If Totosai is not able to do it, then after unifying the country, we will gather the strength of all Onmyoji to find a solution.

Moreover, the Tree of Ages is not the Bone-Eating Well. There is still some distance between the two, and the probability of them affecting each other is very low.

Chapter 45 From resentment to bond, it only takes three seconds

Usami Sadamitsu sat at the table in a daze, letting the tea in front of him get cold without noticing it.

The secrets I heard today were like stepping into myths and legends.

If I go back and report like this, it will definitely be regarded as crazy talk.

While he was pondering, he suddenly heard the sound of the night door.

"What is the relationship between Usami-san and Nagao Kagetora?"

!! ?

Why are you asking this? Shouldn't you be asking me the purpose of my mission, or telling me to keep what happened just now strictly confidential?

"Your Highness Kagetora and I have a relationship of both teacher and friend."

"So, you are loyal to Nagao Kagetora himself, not the Nagao family?"

"I don't think there is any difference between the two. The only one who can keep the Nagao family going is Kagetora-sama."

"That's not wrong. It seems that Mr. Usami is a loyal minister."

Usami Sadami looked surprised, but quickly reacted.

Judging from the casual chat they just had, they seemed to be people from the future who traveled through time and space from five hundred years later.

Speaking of which, the temperament and conversation of these people are incompatible with this era, and they really don't seem like locals.

"Could it be that the Usami Sadami in historical records was a rebellious person?"

"That's not it."

Ye Men shook his head slightly, recalled the historical records of Usami Sadami, and sighed:

"Due to insufficient historical data, there are two mainstream accounts of Usami Sadami in history."

"First, Usami Sadamichi rebelled in his later years. The evidence is that after his death, his entire clan was exiled and never set foot in Echigo again. This statement is the traitor's theory, and it is believed that Usami Sadamichi was an ambitious person."

"Second, Usami Sadamichi is loyal and believes that it is impossible for Nagao Kagetora to deal with Nagao Masakage given his character."

"But Nagao Masakage was ambitious and would rebel sooner or later. For the future of his family, he invited Nagao Masakage to go boating alone in the lake, and they both drowned in the middle of the lake, perishing together."

"Compared to the first one, I personally prefer the second one, the loyal minister theory. Although it is regrettable, it is also the romance of this era."
