Du Tao sent a large number of people to various cities to purchase goods according to Xiao Yu's arrangements, and the result was satisfactory. In just two days, the number of recipes was as high as 100% and the number of various materials was extremely large. The major city lords did not know the importance of the recipes and many magical materials that were temporarily useless. The purchase cost was much lower than the budget, and the travel expenses were only used for a whole day.

After Du Tao sorted out the materials, they were all sent to Xiao Yu. Xiao Yu was very satisfied with Du Tao's efficiency. There were many types of alchemy formulas he purchased, most of which were more ordinary and more general formulas, but there were also two precious and rare formulas mixed in.

"Low-level physical energy explosion potion", second-level potion, material: dark grass essence, magic crystal (green) powder, low-level magic dissolver. Effect: After use, temporarily stimulate potential, increase the speed by 50%, increase the mental power by 25%, and maintain the effect for fifteen minutes. Side effects: within half an hour, the speed will drop by 50%, and decrease the mental power by 50%.

"Low-level vitality potion", second-level potion, material: blood coagulation herb essence, magic crystal (green) powder, low-level magic dissolver, lower-level life ice crystal. Effect: Quickly recover from injury after use. Side effects: Healing agents cannot be reused within ten minutes.

These two magic potions are very useful, especially the "lower level vitality potion", which is the same as the "lower level mental potion" potion, and are precious consumables. The cost of making life potion is much the same as that of the mental potion, but the concentration grass, one of the main materials, is changed to a blood coagulation grass. This is a life-saving thing. After mass production, I believe that many people will spend a lot of money to buy it.

"How much reserves do we have in the blood coagulation grass?"

Du Tao replied: "About thirty plants, the lower-level blood coagulation grass is a specialty of Stormwind City, and has certain effects on the treatment of injuries, so it has always been in short supply and the price is very high."

Stormwind City?

Xiao Yu was slightly stunned. His previous life was the main city of the Evil Emperor and one of the famous cities on the mainland. This Evil Emperor was once the boss of a gangster in a certain island country. He was indeed a top master, but he did not have any dignity as a master. He was very different from his personality and had no principles or bottom line at all. He was forgiving his righteousness when he saw profit, betrayed his faith, and was extremely arrogant and arrogant, and most powerful people were disdainful to join him.

In fact, Wentiancheng had never bought blood coagulation grass from Stormwind City. The batch in the warehouse was given to Han Kexin as a gift, but was all put into the warehouse.

Xiao Yu said, "Get all the blood coagulation herbs, and go to Stormwind City to buy a batch. If it is more expensive, it is more expensive. We are not short of this money." Halfway through his words, he suddenly heard something and said, "By the way, I need a laboratory, and I need to put all the alchemy materials into the laboratory in a quiet enough place, and no one is allowed to enter."

"Yes, the city lord."

Most potions require magic dissolvers and magic crystal stone powder. The role of magic dissolvers in alchemy is to dissolve various materials and play a neutralizing role. They can be made by themselves and can be extracted from many magic plants, but they are quite troublesome. You can buy them in goblin stores, and the price is not too expensive and it is a basic product that must be found in every issue.

Xiao Yu came to the hall and opened the secret realm of the Epic Tower. The secret realm of the goblin store was just opened. He brought enough soul gems in the secret realm. The goblin store was still the same, magical synthesized life No. 9 stood on the counter with a dull face, and the room was filled with goods. Xiao Yu was not like last time, but he was carrying a huge sum of money.

Twenty first-level inheritance crystals, three second-level inheritance crystals, and one precious third-level inheritance crystal. There is no doubt that you will buy them all.

Xiao Yu said to No. 9: "I need to buy low-level magic dissolvers."

No.9 pointed his hand at several huge crystal bottles in the corner and said dumbly: "Commodity No. 193, low-level magic dissolver, priced at two intermediate gems per ten grams."

The magic dissolver is in units of ten grams, because the dissolver used for a potion is about ten grams.

Xiao Yu said, "I want it all."

No.9 said dumbly: "A total of one kilogram, a total of two hundred superior soul gems."

Xiao Yu frowned, "Two hundred superior gems... are really a lot, but it's enough to make one hundred potions, and the profit should be several times higher." As he said that, he took out two hundred superior soul gems and gave them to No. 9.

The dull voice of No. 9 sounded again, "The No. 193 commodity barrier was lifted."

Xiao Yu walked over and saw that the low-level magic dissolver was loaded in ten crystal bottles, each with a standard weight of 100 grams. The solution was colorless and bright, and on the surface it looked no different from ordinary water. After putting it in the ring, Xiao Yu searched in the store for a moment and saw a huge wheel cannon, which looked a bit like a cannon, with two large wheels, the diameter of the cannon barrel was about a foot, the overall diameter was smooth and shiny, and a large number of magic symbols were engraved.

"Gomin Low-level Magic Cannon", a blue medium-grade, magic technology product, has powerful destructive power, level 4 attack intensity, optimal range of 5,000 meters, and requires consumption of spirit gems. The price for sale in the low-level goblin store: 450 superior soul gems.

This is a blue-grade magic technology product, the price is as high as 450 superior gems, which looks a bit horrible, but Xiao Yu understands that the goblin magic cannon is a symbol of the Goblin tribe's famous continent, and its power and destructive power are enough to make any powerful opponent tremble.

The magic cannon is one of the most important inventions of the Goblin tribe. It is almost a symbol of the force of the Goblin tribe. The probability of this product appearing in the Goblin shop is very low. This time, there are some assets that happen to hit. Of course, it cannot be let go. With this cannon in hand, Wentian City's defense power can be doubled, which is not an exaggeration at all! Of course, the consumption and power of the magic cannon are also terrible. Only the spirit gem can be activated. A lower-level spirit gem will be exhausted after two cannons, which is equivalent to killing five upper-level soul gems with one cannon.

Xiao Yu gritted his teeth and took out 450 superior soul gems to buy magic cannons. Less than three days after he came back, Wentiancheng's savings of one month were squandered by half. This is not the end. Xiao Yu found a batch of green-grade magic weapons in the goblin store. Each piece of Qingjing costs twenty or thirty superior gems, and it costs more than 140 superior gems to buy. In addition, Xiao Yu bought a bunch of magic scrolls, which are important consumables, which can enrich Wentiancheng's warehouse, and can also sell them to make profits. A total of 200 gems were spent.

"Magic Crystal Crusher", a white top-quality tool used to process magic crystals into powder.

Xiao Yu unexpectedly saw this thing. Most potions require magic crystal powder. It is much more convenient to have a special powder processing tool and the price is very cheap. I bought it without hesitation.

After roughly estimating, thousands of superior soul gems have been used.

This number has exceeded more than 90% of the total wealth of the city. Wentiancheng's movable assets have been used up by Xiao Yu. There are still many purchase-worthy things in the goblin shop, but Xiao Yu had to give up. After all, Wentiancheng still has more than 3,000 people, and breeding farms and plantings. Whether internal or diplomatic, there will always be fixed consumption. If the movable assets are hollowed out, it will be impossible to maintain the welfare of residents and regular troops, and the impact will be very bad.

Xiao Yu left the goblin store and handed the magic cannon to Han Kexin for safekeeping. She asked her to arrange for people to build a strong enough artillery tower on the city tower to specifically accommodate magic cannons to ensure that the precious magic cannons are not damaged in war and can exert their maximum power.

The laboratory is arranged.

Xiao Yu came to the laboratory, and Du Tao found the quietest room according to his request. The entire laboratory was filled with various materials. Xiao Yu made it in front of the table and selected all the materials he could use.

Alchemy has begun.

Xiao Yu first made the "low-level vitality potion". He took out the thirty existing blood coagulation herbs. After the red lotus fire was extracted, there were only eight parts of the blood coagulation herb essence. In other words, it was only enough to make "low-level life water" eight times. Xiao Yu took out one of the blood coagulation herb essences, took out ten lower-level life ice crystals, a magic crystal (green) powder, and a magic dissolver, and put it in a crystal bottle for alchemy.

A complex magic array appeared between the two palms, and crimson flames gushed out from the surroundings. Potions mixed with various materials reacted in the middle of the magic array, gradually boiling and glowing, and a breath full of magic power emitted, and the red light became brighter and brighter.

Sudden.

Bang!

With a crisp sound, the entire crystal bottle exploded and shattered.

Failed.

Xiao Yu frowned, "The alchemy magic array is built according to the requirements of the formula, there must be no problem, come again."

Xiao Yu took out a piece of material again and refined it in the same way. Various materials reacted under the action of the alchemy magic array. The ingredients gradually extracted and fused, and the gorgeous red light burst out from the crystal bottle, and finally gradually converged and condensed, and finally a small bottle of crystal clear liquid was left.

"Low-level vitality potion", green low-quality, magic potion, effect: Obtain the "Minor Injury Treatment (Level 1)" effect every five seconds, and last for one minute. Side effects: Within ten minutes, therapeutic potion is ineffective.

"Haha...it's been successful! It's been successful!"

Xiao Yu almost jumped up excitedly. He really made a life potion as he wished! This is a life potion, an instant recovery potion that can be used in battle! Its value is immeasurable!

A bottle of "Low-level Body Vitality Potion" has an effect of one minute, and a minor injury treatment is obtained every five seconds, which is equivalent to a total of twelve "Minor Injury Treatment" effects. Although it is a first-level healing magic, it is superimposed to twelve times, which is enough to heal most ordinary injuries.

Calculate the cost.

One portion of blood coagulation herb essence, ten portions of lower-level life ice crystals, one portion of green magic crystal powder, and one portion of magic dissolver... The sum of it is absolutely no more than five superior soul gems. Xiao Yu thought that it is easy to take out the potion now and sell thirty or forty superior soul gems.

Of course, there is another factor in the success rate of making potions. Not every time they are made, but no matter what, the profit is extremely high. Xiao Yu has a powerful flame like "Red Lotus Hellfire", and the success rate of alchemy should be quite high, but he is not skilled enough at present.

Now there is an urgent need for a large amount of materials, especially the concentration grass that makes mental potions, and the blood coagulation grass that makes vitality potions!
