I opened the treasure chest in Demon Slayer: Kimetsu no Yaiba

The headquarters of the Ghost Slayer Team, where the Sanyashiki family is located.

"Mr. Scale, I haven't seen you for a long time, are you okay?" Yaoya said politely to the scales.

"My old bones are fine, the head of the family should take good care of his body, and you have to worry about the affairs of the ghost killing team!" Scales looked at Yaoya with concern.

"My body has always been like this, and the limit is approaching, and the ghost killing team will inherit it in the future, and the ghost will not be destroyed for a day, and the battle between the Sanyashiki family and the ghost will not stop!" Yaoya said indifferently.

"Indeed!" Scales nodded his head recently: "If the ghosts are not eliminated for a day, we will not have a day to stop, and the battle will continue!" "

"Speaking of which... Yaoya suddenly paused and continued: "Two days ago, I received a piece of news, a news from the Grand Priest, that there are ghosts on their side, and it seems that they are preparing to do something to them! "

"What ??"

Scales were taken aback for a moment: "Could it be that Onimai Tsuji is going to make a move against the priest clan?" "

"I'm not sure for the time being, but the priest family did find traces of ghosts!" Yaoya said in a deep voice: "I hope it's not what we think!" "

When Haneda Ryu heard this, his eyes moved, but he didn't say anything.

"We've already sent Sound Pillar and Snake Pillar to investigate, I hope we've thought too much!" Yaoya said.

"Hopefully!"

。。。。。。

Butterfly House, inside the laboratory.

Chanae and Butterfly Shinobu were experimenting, and after the two returned to the Butterfly House, they didn't care about anything, and they devoted themselves to the study of mental power potions and physical strength potions, which lasted for several days, and today they finally had some results.

"Sister, we seem to be about to succeed!" Butterfly Shinobu looked at the finished product in front of him and said happily.

"You can't be happy too early, you have to find a chance to test the effect!" Holding a bottle of the researched potion in her hand, Chana Hui was also very happy in her heart, but she didn't show it, and the actual effect still depends on the clinical results.

"Didn't Yin send a few seriously wounded people? Let's test them out! Butterfly Shinobu said, "Anyway, even if it doesn't work, nothing will happen!" "

"It's different, this is not the original healing potion, but a comprehensive potiony that we have researched by combining mental power potions and physical strength potions that can restore physical strength and mental strength at the same time!" Chanae said, thought for a moment and said, "I'd better try it myself!" "

"This... Sister, why don't you let me come? Butterfly Shinobu suddenly objected.

"It's decided!" Chanae didn't want her sister to be in danger, even if it wasn't too dangerous.

Seeing her sister's determined look, Butterfly was moved in her heart, but she did not continue to be willful.

"Since it is to restore physical and mental strength, then I need to consume some physical and mental strength first!" Chanae first went to the courtyard and used a lot of Flower Breath tricks and consumed a lot of physical and mental strength before she was panting and drank the potion she had researched.

As soon as the potion was in the stomach, it had an immediate effect, and after a burst of fever, the head area was cool, and then Chanae immediately felt the difference, the mental power and physical strength she had just consumed were rapidly recovering, but it had already recovered to its peak in a few minutes, even better than before!

"It works very well!" Chanae exclaimed happily.

"Really, sister!" Butterfly Shinobu also looked at Chanae happily.

"Of course it's true!" Chanae nodded, and then said: "However, the raw materials of this potion are the two potions provided by Haneda, and the current raw materials of those two bottles can only make about twenty bottles of this elixir, and if you want to continue to do it in the future, you still need him to provide the original solution!" "

"Well, if you say that, it's impossible to produce it in large quantities?" Butterfly couldn't bear to hear this, and immediately sighed.

"Of course not, this kind of anti-heaven elixir is the same as a healing potion, the healing potions can revive the dying, and the large amount of recovery potions we dilute and produce can only restore injuries!" Megumi Chana said, "The amount we made is indeed huge, but the effect is far less than the stock solution provided by Haneda!" "

"I don't know where that guy got these good things!" Butterfly muttered.

"No matter where he came from, he has done a great job of providing us with research!" Chanae smiled and looked at Butterfly Shinobi: "Sister, Haneda is a very good person, his personality is good, he is also very handsome, and his strength is strong, you, you can think about it more, I specially introduced you to him before, you see that you have gotten along well during this time, and you can develop in a deeper direction!" "

"Oh, sister, what are you talking about!"

Butterfly Shinobi's face turned red suddenly.

"What did I say?" Chanae grinned: "I'm thinking about your life's work!" "

"Then you're my sister, and what about your own life's work?" Butterfly pouted: "If you don't get married, I won't get married either!" "

"Nonsense!" Chanae shook her head, but did not continue to discuss this topic with Butterfly Shinobi, but said, "What is the name of this potion that we have researched that can restore both physical strength and mental strength?" "

"Body essence potion?" Butterfly Shinobu touched her lips and suggested.

"What the hell is the name?" Chanae rolled her eyes.

"That... Sperm elixir? Butterfly Shinobu continued.

"Go, go!"

Chanae waved her hand suddenly, and then thought for a moment and said, "Why don't you call it a salvation potion?" What do you think? "
