Chapter 1470

After checking the attributes of the 【Ancient Secret Medicine (Improved Version)】, Su Xiao was quite surprised. Because he considered the addition of Reishi and the manufacturing cost, he greatly reduced the initial effect of the Ancient Secret Medicine. Humans drinking this bottle of potion could only restore 21% of their HP, which was equivalent to a green-quality potion.

It was precisely this significant reduction that lowered the manufacturing cost a lot. Now, Su Xiao manufacturing one bottle of 【Ancient Secret Medicine (Improved Version)】 required about 80~100 Mana points. If skilled enough, the Mana required for each manufacture could even be reduced to about 60~80 points.

For Su Xiao, whose Mana limit reached 6076 points, as long as there was a sufficient quantity and enough materials, he could manufacture nearly a hundred bottles of this potion in a short time.

Materials were indeed not the core; the core was the Reishi compressed into a semi-solid state. If the Devour Core hadn't broken through its upper limit twice, Su Xiao wouldn't have been able to do this.

The recovery effect of Shinigami drinking the 【Ancient Secret Medicine (Improved Version)】 was 4 times, which was a very considerable recovery amount. Not only that, drinking this thing could also permanently enhance Reiatsu.

Although it only increased by 0.2%, it was still an improvement. No matter how subtle the improvement was, captain-level Shinigami could perceive it. As for the upper limit of 3%, Su Xiao wouldn't let the Shinigami know about this.

If operated properly, Su Xiao could even give the Shinigami an illusion that this potion could increase Reiatsu without limit. In that case, he wasn't afraid that the Shinigami of the Seireitei wouldn't take the bait.

Su Xiao didn't expect that the 【Ancient Secret Medicine (Improved Version)】 could actually increase Reiatsu. He just prepared it according to the original preparation method of the Ancient Secret Medicine. Judging from the current results, this was caused by the properties of the Ancient Secret Medicine.

When he first obtained the Ancient Secret Medicine formula, Su Xiao had seen such a paragraph in the introduction of the Ancient Secret Medicine: "After mastering this formula, you need to be extra cautious. You will become a precious talent that many major forces in derived worlds/war worlds/native worlds will try to win over or snatch."

Judging from the current effects of the alchemical secret medicine, its introduction was not exaggerated, but rather somewhat understated.

"It seems... I need to change the plan appropriately."

Su Xiao stood up and came to the sliding door, pulling open the wooden door. Standing in front of the door were two Shinigami. These two Shinigami were nominally protecting him, but in reality, they were monitoring him. Now Su Xiao was under house arrest, but he didn't care about this at all.

"Please inform Captain Retsu Unohana that the Ancient..."

Su Xiao was just about to say the name "Ancient Secret Medicine" when a thought suddenly flashed through his mind: rename the Ancient Secret Medicine (Improved Version) to make it sound more mysterious.

"Tell her the 'Soul Spirit Medicine' has been prepared."

Su Xiao held a crystal bottle between his fingers. This crystal bottle looked very exquisite, but in reality, it only required 15 Paradise Coins to exchange for it in Reincarnation Paradise.

A mysterious name, high-end packaging, and exaggerated effects due to limited quantity—with this three-hit combo, Su Xiao didn't believe he couldn't stun the Shinigami of the Seireitei.

A slightly chubby Shinigami in front of the door took the alchemical secret medicine—no, now it was called Soul Spirit Medicine...

After Su Xiao handed over a bottle of Soul Spirit Medicine, he began to manufacture more. He had to ensure that he had at least 50 bottles of this thing in his hand. As for how many to hand over, due to the limited "output," 7~10 bottles a day was the maximum. As for mass production? After mass production, the Shinigami would completely figure out the characteristics of the Soul Spirit Medicine, and the value of this potion in the hearts of the Shinigami would be greatly reduced.

A potion that saves lives at critical moments + permanently enhances strength—Shinigami were not saints; they had desires just like humans. Su Xiao didn't believe they wouldn't be tempted.

As he repeatedly made the Soul Spirit Medicine, Su Xiao became more and more proficient. When his Mana was only 400 points left, he had already manufactured 16 bottles of Soul Spirit Medicine, all of which were stored in his storage space.

Researching and manufacturing potions for a whole day and night was a significant overdraft of mental energy. Su Xiao fell asleep as soon as he lay down. The Seireitei was very safe for him now. Once the effects of the Soul Spirit Medicine were announced, if any contractor wanted to kill Su Xiao, those captain-level Shinigami wouldn't sit idly by. At least four captains wouldn't: Retsu Unohana, Sosuke Aizen, Genryusai Shigekuni Yamamoto, and Nemu Kurotsuchi.

After Su Xiao took a nap for half an hour, Retsu Unohana came to visit. With her concentration, even if she knew what the Soul Spirit Medicine represented, she remained calm.

Su Xiao yawned, looking a bit sleepy, with a coat draped over his shoulders.

"That potion, I had someone test it. It's very good."

Retsu Unohana got straight to the point, looking at Su Xiao with burning eyes.

"Oh."

Su Xiao had just been woken up after sleeping for half an hour and was clearly still a bit confused. It would have been better if he hadn't slept; being woken up after sleeping for a while made him even more drowsy.

"It can be mass-produced. By the way, I'll help you change to a new residence."

"Mass production is somewhat difficult."

The lazy-looking Su Xiao spoke. His disguise was becoming more and more proficient, or rather, he had already entered the state.

"Hmm?"

Retsu Unohana frowned, and the smile on her face faded.

"You should have tested the effect of that potion. To tell you the truth, preparing the potion is not difficult; the difficulty is in extracting the semi-solid Reishi. This Reishi must ensure its biological properties. Natural Reishi is equivalent to a stone; even if you eat a stone, you can't absorb it. Transforming Reishi from an 'h' form into a biological form and forming a semi-solid state is like..."

After Su Xiao described it for at least five minutes, Unohana, who was proficient in healing abilities, was a bit confused. She experienced the feeling Hitsugaya had earlier.

"I don't understand. Please speak human language."

It was very obvious that the confused Unohana belonged to the more straightforward type.

"In principle..."

Hearing the word "principle," Unohana waved her hand. She had already guessed that she probably wouldn't understand the next few hundred words either.

"To be blunt, how many bottles can be mass-produced per day?"

"If I work harder, about eight bottles. You can consider abandoning this model. If you don't consider the increase in Reiatsu, mass production should be no problem, but it also needs to be mixed with semi-solid Reishi."

Su Xiao's meaning was very simple: except for him, no one could manufacture this kind of potion.

This was indeed the case. He was able to manufacture the Soul Spirit Medicine as a result of Alchemical Pharmacology + Devour Core + research experience. As for the Devour Core, not to mention the Bleach world, looking at the entire Void, only two people possessed it. One was Su Xiao, and the other couldn't manufacture potions.

Hearing the eight bottles Su Xiao mentioned, Unohana started to get a headache. A potion that permanently enhances Reiatsu while ensuring no harm to the body—this was the only one in the Soul Society.

"Follow me, someone wants to see you."

Unohana stood up and walked out of the room. Su Xiao, draped in a coat with a lazy expression, followed at a distance, enjoying the scenery of the Seireitei along the way.

Soon, Retsu Unohana brought Su Xiao to a wooden building. This wooden building looked a bit old but had a sense of majesty. The character "One" was written on the wooden building. This was the center of power of the Gotei 13, the station of the First Division.

As for the person Su Xiao was about to see, one didn't need to think to know it must be Genryusai Shigekuni Yamamoto, the Captain-Commander of the Gotei 13. He possessed absolute authority in the Soul Society, and his life was almost equivalent to the history of the Soul Society.
