In the exclusive room, Su Xiaopan sat on the bed, holding two treasure chests in his hands, all of which were epic treasure chests, one of which was dropped by the big boss Saint Zaga.

As a lucky attribute as high as 8 points, the 'European Emperor' who can temporarily reach 12 points, Su Xiao is more confident in opening the treasure chest this time.

With a snap, the cigarette was lit, and the state of the European Emperor was added, and Su Xiao took the lead in opening the treasure chest dropped by the Black Abyss Wulong.

The harvest of the treasure chest, Su Xiao was not surprised, he just slaughtered a wulong, and it was impossible to open an item such as the Dragon Slaying Sword or the Black Dragon Secret Book when opening the treasure chest.

There was not much time for the European Emperor state, and Su Xiao opened the treasure chest dropped by Saint Zaga.

……

Su Xiao's heart couldn't help but beat faster, because he noticed a sentence, 'It can create a permanent buff potion', what kind of concept this is, he couldn't know it very well.

[Yes/No Mastery of Advanced Knowledge of Alchemy: Plant Harmony Chapter.] 】

"Mastery."

As soon as Su Xiao's words fell, a large stream of information melted into his mind, fortunately his physique was strong enough, otherwise this would be enough to make him faint.

[You have unlocked the advanced knowledge of alchemy, plant harmony. 】

[You have mastered Plant Harmony Lv.1.] 】

You have unlocked a new recipe: Vitality Potion. 】

[Vitality Potion: Each manufacturing requires 300 mana points, and requires consumable materials, Soul Essence, Source of Origin, Source of Vitality, Urnoflower Juice, Life Polymer C, Life Polymer T, Ridding +, Crystal Bottle. 】

[Effect: After drinking/injecting, permanently increases the physical strength attribute by 2 points (this potion's physical strength attribute takes effect below 20 points, and repeated use is invalid, and it will produce poisoning). 】

……

From Su Xiao's fourth-order contractor's point of view, the vitality potion is actually not very good, but don't forget that this is only the formula of the 'Plant Harmony Chapter Lv.1', and as this ability increases, the permanent buff potion produced by Su Xiao will become stronger and stronger.

Moreover, the vitality potion is not without a market, if Su Xiao starts to make this thing to improve the proficiency of the 'Plant Harmony Chapter Lv.1', then he is the father of the first-order contractors, even if those newcomers are allowed to smash the pot and sell iron, they will find a way to buy a bottle.

After Su Xiao gathered the items from the treasure chest, the [Chain of Fraternity] was handed over to Beni and Bubuwang to sell, as for the pile of black dragon products, except for the [Black Dragon Fang], all the others were packed to Reed, and that guy was willing to buy the materials at a high price.

Right now, Su Xiao needs a large amount of Paradise Coins as a turnover, and he is ready to appropriately improve the ability of 'Plant Harmony Chapter Lv.1'. There is no doubt that the finished vitality liquid will sell very well, but this also requires a lot of money, and Su Xiao is not interested in making a bottle and selling it one bottle at a time.

Secondly, the funds will be used to repair an epic sniper rifle in the future, provided that the sniper rifle actually arrives.

Bennie's side can probably sell about 50~600,000 paradise coins, after all, that legendary piece of equipment is too strange, for very few people, it is a treasure, but for 99.9% of contractors, that thing has no use, but will make you die faster.

As for the black dragon products on Reed's side, the other party gave a price of 860,000, after all, it was just a bunch of materials, and the price was not low.

After Su Xiao rummaged in the storage space, he found a bottle of elixir, [Polymeric Acid Enhancement Elixir], this bottle of legendary-level elixir was most suitable for selling to second- or third-order contractors, so he contacted the God Emperor, they had many second-order or third-order members.

After some bargaining, the [Polymeric Acid Strengthening Elixir] sold for 890,000 Paradise Coins, and after waiting for about half an hour, Beni quickly sold the [Chain of Secret Love] at an ultra-low price of 490,000 Paradise Coins, so that Su Xiao's assets reached 2.29 million Paradise Coins, which was extremely tyrant.

However, in addition to consuming 300 mana points, the cost of each bottle is nearly 28,000 Paradise Coins, Su Xiao seriously doubted whether the first-order contractor could afford it, considering the gain of 2 points of physical strength attribute to the newcomer (the highest attribute of the newcomer is about ten points), if Su Xiao sells 30,000 bottles, those newcomers will grit their teeth and buy a bottle nine times out of ten.

Needless to say, as long as the level of Plant Harmony Lv.1 can be raised, it will definitely become one of the important economic sources in the later stage, and when joining any faction, the ability to create permanent buff potions will give you a lot of power.

Su Xiao entered the alchemy laboratory, and after exchanging Paradise Coins for materials, he began to make vitality potions, but he soon found that it was very difficult to make permanent buff potions.

If the difficulty of crafting a Recovery Flask is 3, then the difficulty of concocting a Permanent Buff Flask is at least 70 or more.

Sweat slid down Su Xiao's sideburns, and the rows of test tubes on the laboratory table were either gurgling and bubbling, or calm as solid, and before he knew it, he was addicted to making permanent buff potions, which was difficult, but it was very interesting and very expensive to make.

Separated, blended, diluted, and finally snapped, and a bottle of emerald green elixir burst open in Su Xiao's hand, dripping down the tips of his hair.

There are only 150 mana points left at 7,326 points, and 672,000 Paradise Coins, Su Xiao has not made a bottle of vitality liquid, but he feels that it is already very fast, as long as he can make the first bottle and has the least experience, it will not be so difficult to make it after that.
