Chambord Islands, Mangrove District 72, inside the underground base.

Su Xiao was concentrating on mixing the potion in his hand, when a sudden knock on the door interrupted his manufacturing, the energy particles in the solution turned white, and the fine ice crystals covered the wall of the test tube, and the preparation failed.

Bubuwang opened the door, and as expected, it was Kerra, who carried a large tray with all kinds of delicacies in her hand.

"Hey, what's going on with this amount of production, how long have you not rested."

Kerra saw the stigmata potions placed side by side on the metal table, and walked briskly into the room.

Hearing this, Su Xiao picked up the timer on the table, which showed 49 hours and 26 minutes, that is to say, he hadn't closed his eyes for two days, this may be the only shortcoming of alchemy, once you concentrate on research, it is easy to indulge in it.

"About two days."

“……”

Kella was speechless for a while, and a sense of guilt appeared in her heart, she had always suspected that Su Xiao had ulterior motives, but now, Su Xiao was helping the revolutionary army to make stigmata potions day and night, which made her conscience very painful.

"If nothing else, take these potions, and you're good to go.

"Uh~"

The guilt in Kerra was gone, and she was even speechless by Su Xiao, so she could only put away the stigmata potion on the metal table and leave the room.

Bang!

The door was closed, and Korra's lips opened and closed outside the door, and finally she could only walk away in a slightly depressed manner.

Su Xiao sat on the wooden bed in the room, opened the alchemy skill tree, and checked the plant harmony chapter.

[Plant Harmony Lv.8 (Mastery: 304/80)]

Lv.1 Unlock Recipe: Vitality Potion (Permanently increases the stamina attribute by 2 points after drinking, and this effect attribute takes effect below 20 points).

Lv.3 unlocks the recipe: Stigmata Elixir (Permanently increases 1 Strength attribute, 1 Agility attribute, 100 HP after drinking, and this effect attribute takes effect below 20 points).

Lv.8 Unlock Recipe: Ancient Potion (Permanently increases the intelligence attribute by 2 after drinking, and this effect attribute takes effect below 50 points).

……

Su Xiao tried to improve the plant harmony chapter, knowledge skills can be improved in the derivative world, this he has practiced many times, the paradise coins needed to improve the plant harmony chapter are not much, the constant 10,000 points per level, the required proficiency is the most difficult to accumulate.

[Plant Harmony has been upgraded to Lv.9.] 】

[Plant Harmony has been upgraded to Lv.10.] 】

[Plant Harmony has been upgraded to Lv.11.] 】

[Unlocked a new recipe: Flame of Dawn.] 】

[Flame of Dawn: 480 mana points per craft, materials consumed, soul essence, sourceless fountain, dawn crystal, power birth, life polymer H, life polymer C, crystal bottle. 】

[Effect: After drinking/injecting, permanently increases 3 strength attributes and 3 stamina attributes (this potion attribute takes effect below 50 points, and can be fatal if used repeatedly). 】

……

Su Xiao looked up at the hint, and he couldn't understand why the unlocked formula had an explosive increase after the Elixir Harmony Chapter was upgraded to Lv.10.

A large amount of knowledge was integrated into his brain, coupled with a long time of potion dispensing, which made Su Xiao's brain a little dazed, and after initially understanding the new knowledge in his brain, he knew why the formula had been explosively improved.

If he can increase the Plant Harmony to Lv.20, he will be able to concoct a permanent buff potion that can be used with 80 or less attributes, and if he reaches Lv.30, he will unlock a recipe that can be used with more than 80 true attributes, and he will be able to drink it himself.

It's good to be able to raise the Plant Harmony Chapter to Lv.20 in the near future, but as for the upgrade to Lv.30, the possibility is not too great, and it's unknown whether the materials needed for that level potion can be scraped together in the Pirate World.

Su Xiao was lying on the bed, seeing this scene, Eminem in the room was sitting in front of the door to block the door, and Bubuwang was penetrating the wall after integrating into the environment, and went to the ground above the base to guard against the enemy.

After sleeping for more than eight hours, there was a vibration sensation from the ring on Su Xiaowei's finger, and he immediately opened his eyes, in the derivative world, he would not completely relax and rest.

"Eminem, go and inform Kella and tell her that she doesn't need to prepare the previous materials."

Not long after Eminem informed Kerra, Kerra, wearing a green dress and short dress, hurried over, she was wearing light makeup, and her appearance changed, and it looked like she was going to perform a sneak-up mission.

"Is something wrong?"

Kerra looked at Su Xiao with a straight face, now the headquarters attaches great importance to the stigmata potion, so there must be no problems.

"You've experimented with those potions before."

"Well, it works great."

Kella was quite reserved, and the news from the headquarters was more than good.

"Now that we have the initial trust, we can start to mix the potions that are suitable for long-term supply."

Su Xiao touched his chin as he spoke, smiling, he had already let the revolutionary army taste the sweetness, it was time to let the other party know how much money was burned in the plant harmony chapter, for this reason, he didn't even choose to mix the ancient magic potion with higher consumption at the beginning, you know, the higher the quality of the potion, the more proficiency will be obtained after the successful blending, if it is the ancient magic potion before, the proficiency obtained in the same time will be more than three times higher.

Su Xiao stayed awake for two days and two nights in a row, just to let the revolutionary army know how important the potion he concocted, and now that he has just mastered the formula of the Flame of Dawn Elixir, the success rate is not high, if he uses the Paradise Coin to resist, it will be a terrifying number.

"What?"

Kerra was a little dazed, and the tone she listened to Su Xiao, the stigma was clearly a very weak elixir, just to establish initial trust with them.

"I told you before, stigmata is a recipe I developed a long time ago, the effect is not strong, long-term blending, Dawnflame is a better choice, if you are ready to let me mix stigmata for a long time, then I will consider leaving the revolutionary army, and mixing that initial potion for a long time is boring."

"Wait, let me gather my thoughts."

Kerra rubbed her forehead lightly, and she felt that things were starting to get tougher, and the foreboding she had felt before was even stronger.

"This is the material needed by Flame of Dawn, if there is a problem with the material, let the headquarters contact me directly."

Kra took the list when she heard this, and this time her expression didn't change, because she hadn't heard of most of the material on it, which was also equivalent to rarity.

"I'll report this to HQ, but the third batch of Stigmata has already arrived, otherwise ......"

Su Xiao didn't speak, just smiled and looked at Kerra at each other.

"You can't go back, ha, haha."

"Go back."

"Let's discuss, these materials are shipped from special channels, and the cost is very high~"

Kellah was pitiful, but ......

"I'm not interested in continuing to make that kind of defective product, so I'll go back."

Su Xiao didn't want to continue to be tired and half dead, so he decisively refused.

"You should, it's not a woman."

Kerra was so angry that he almost stomped his feet.

“……”

"Since you insist, you can only go back, by the way, are you interested in accepting a disciple, I am very talented."

Kella changed her strategy and wanted to solve the problem at its roots.

"1476×48334+1573459+4347762, give me the answer in ten seconds."

“？”

Kella looked at Su Xiao blankly, she didn't even remember how many numbers Su Xiao said, but she thought of one thing instead, and asked rhetorically: "Then you say, what is the answer." ”

"77262205, numeracy is the most basic discipline of alchemy."

"This ......"

Kella was surprised to find that she couldn't be sure whether Su Xiao's answer was correct.

"Go and inform the headquarters, your IQ won't allow you to study alchemy."

Su Xiao turned off the calculator on the tablet as he spoke, in fact, alchemy and mathematics were not too directly related.

Kerr took a long sigh of relief and calmed herself down, the other party is an important staff member, she can't have conflicts with the other party, and if she can't beat it, it's a matter of death, so she can only endure it, and if she can't beat it, she won't be ashamed.

In the afternoon of the same day, the materials that Su Xiao needed arrived, and he began to try to mix new potions.

Three hours later, there was a crisp sound, the test tube burst open in Su Xiao's hand, and the blending failed, he was not discouraged, the material was not his money, and he was not distressed at all.

Provisioning Failed, Provisioning Failed, Provisioning Failed......

After more than a dozen failures in a row, Su Xiao's mana value was only more than 400 points left, and after he sat cross-legged on the bed and meditated for more than three hours, his mana value recovered to full.

Time passed quickly, and before I knew it, it was already two days before the start of the battlefield on the top.

Su Xiao shook the test tube in his hand, the orange elixir shook in the test tube, and there was a flame burning in the liquid medicine, this was the Flame of Dawn Elixir.

Glancing at the 49 bottles of Flame of Dawn Elixir on the table, nearly 270 materials, only 49 bottles of finished products were produced, if Su Xiao was responsible for the loss of materials, it would be cutting meat.

Mixing stigmata potions, each successful blend can only get 1 proficiency point, Flame of Dawn is different, a successful bottle can increase 15 proficiency points, which makes Su Xiao gain a total of 735 proficiency points.

Not only that, among the 49 bottles of elixir, he completed a perfect blend, and the properties of the elixir obtained were extremely amazing.

【Flame of Dawn (Perfect)】

Quality: Purple Rare

Effect: After drinking/injecting, it permanently increases the Strength attribute by 5 and the Stamina attribute by 5 (Strength and Stamina stat can be used below 50 points).

……

Su Xiao put down the potion in his hand, just now, the Whitebeard Pirates had already contacted him, and the Moby Dick had entered the second half of the Great Voyage.
