Chapter 1: Low-Grade Alchemy Potion: Each creation requires 120 mana points, Green Fluorescent Grass, Life Essence, Pure Spring Water, Wanda Tree Fruit, and a Crystal Vial.
...
Alchemy Pharmacology has been unlocked. Su Xiao attempts to create [Low-Grade Alchemy Potion], costing 800 Paradise Coins + 120 mana points.
He has enough Paradise Coins on hand, but his mana is running low. Earlier, when learning Demon Power, all the mana in his body was converted into Cyan Steel Shadow Energy.
The attributes of [Low-Grade Alchemy Potion] are unknown for now. Based on Su Xiao's speculation, this potion shouldn't be too weak.
All the gains from the One Piece World have been transformed into strength, and Su Xiao's body and mind gradually relax.
He still has 27,890 Paradise Coins left. Su Xiao leaves his Exclusive Room.
Before leaving the Exclusive Room, Su Xiao glances at Bubu Wang, who is gnawing on a bone. He plans to head to the Trial Grounds, and Bubu Wang doesn't need to come along.
But leaving Bubu Wang alone in the Exclusive Room gives Su Xiao a nagging sense of unease.
"Should... be fine, right?"
Su Xiao leaves the Exclusive Room. One minute after he leaves, Bubu Wang finishes gnawing the bone and looks around.
The owner is gone, so in the Exclusive Room, Bubu Wang has become the boss.
Bubu Wang surveys the surroundings like he's inspecting his territory, considering what to gnaw on next.
...
Inside the Trial Grounds.
Su Xiao slashes off the head of a metal puppet with one strike, then reverses his long blade and stabs it through another metal puppet.
Around him, hundreds of shattered puppets are scattered. He's using combat training, and the surrounding metal puppets are endless and feel no pain.
He has already held out for two hours under the siege of the puppet army—something he couldn't have accomplished before.
The increase in his Stamina attribute has greatly boosted Su Xiao's endurance. A healthy body allows him to swing his blade more freely and effortlessly.
He kicks a puppet away, then swings his long blade in a series of slashes, forming a net of blade light.
Clang.
A sharp edge flashes, and dozens of metal puppets in front are sliced into fragments. Su Xiao, on the other hand, is still in good condition.
Su Xiao's strength doesn't lie in immense power or incredible speed; his expertise lies in technique.
After finishing the combat training, he still has over 20,000 Paradise Coins. Su Xiao ponders. He only needs to keep 7,000 Paradise Coins; the rest he plans to spend in the Trial Grounds.
He activates the auxiliary mode, and a notification from Reincarnation Paradise appears.
[You have selected auxiliary mode. Please choose the level of the summoned mirror image.]
[Low-Level Mirror Image] 100 Paradise Coins per hour.
[Intermediate Mirror Image] 1,000 Paradise Coins per hour.
[High-Level Mirror Image] 10,000 Paradise Coins per hour.
Su Xiao hesitates between summoning an Intermediate Mirror Image or a High-Level Mirror Image.
After a long deliberation, Su Xiao chooses to summon an Intermediate Mirror Image, and specifically designates the target.
[You have selected to summon an Intermediate Mirror Image. Designated character: Uchiha Sasuke.]
[Please select the summoning duration.]
"Eighteen hours."
The reason Su Xiao summons Sasuke is that he wants to discuss the issue of energy-attached weapons with him.
Sasuke mentioned it once before: when Cyan Steel Shadow Energy reaches a certain level of strength, it can develop other properties.
Light surges, and Sasuke's figure appears.
At this stage, Sasuke has already been "lured away" by Orochimaru, his heart full of revenge, at the peak of his rebellious phase.
"We meet again. Same topic as last time: energy-attached weapons."
Hearing Su Xiao's words, Sasuke nods. At this moment, Sasuke is just a mirror image, so even if he's in his rebellious phase, he will still impart the knowledge Su Xiao needs.
"That pure spiritual energy inside you is already quite strong. More importantly, you can now freely control that energy, which is the prerequisite for development."
Sasuke draws the Kusanagi sword from his lower back, and Lightning Release chakra envelops the blade.
With Su Xiao's current insight, he immediately notices the difference. Sasuke's control over energy is very skilled. The Lightning Release chakra wraps around the Kusanagi sword in an extremely balanced manner.
"This is your current problem: uneven energy coverage. But you'll overcome that soon. The real issue now is how to deeply develop the energy within you."
Sasuke begins to explain how he developed his Lightning Release chakra. Su Xiao listens attentively. After a long while, Su Xiao nods.
"You borrowed the inherent cutting ability of lightning."
Su Xiao sits on the ground, a thoughtful expression on his face.
"Right. Many people have developed Lightning Release chakra, but I focused on developing the sharpness of lightning."
Su Xiao closes his eyes in contemplation, while Sasuke stands still without a word.
"If I'm not mistaken, the density of Cyan Steel Shadow Energy is dozens of times that of Lightning Release chakra. Cyan Steel Shadow Energy tends to decompose other energies, which makes this a bit tricky."
Cyan Steel Shadow Energy itself doesn't have a sharp property. To achieve that, Su Xiao would have to rely on his own ingenuity—or more precisely, his creativity.
What method could be used to strengthen Cyan Steel Shadow Energy? This is a thought-provoking question.
Suddenly, a flash of inspiration strikes Su Xiao's mind.
