In the fourth year, the materials in the hands of the three were finally consumed.

The three of them have been busy in this alchemy workshop for more than four years, and have made a total of more than 300 pieces of equipment.

If anyone knew that the two of them had made so much equipment in more than four years, and it was also unique equipment of their own design, they would not be able to believe it.

The drawing of the magic array, there is no room for half a point difference, if you don't pay attention to it, you will fail, once you fail, the loss of alchemy materials don't talk about him, maybe a few days of hard work will be in vain, for an alchemist, which piece of equipment is not a failure piled up.

But one of Bai Qi has a precision talent, the other has a wise heart talent, one has a crazy love for alchemy, and the other is as calm as ice once the talent is stimulated, and there will be almost no mistakes in the alchemy process, and this speed will naturally increase.

It is not only the speed that is improved, but also the profit, the failure of the inscription circle, there is no loss for the main material, the grinding and removal of the failed circle, or the return to the furnace for refining, can be reused, but the auxiliary materials used to engrave the circle are lost.

For ordinary alchemists, a piece of equipment is refined, and even used with waste, the Chen Ben of auxiliary materials is often higher than the main material, but Bai Qi and Barian refine a piece of equipment, and the cost of auxiliary materials used is only one-third of the main material, just this one, Bai Qi's profit is more than twice as high as that of ordinary alchemists.

Bai Qi and the two of them refine an average of one piece of equipment a week, which is already an incredible opportunity in the eyes of ordinary alchemists, which can also be seen from this. The efficiency of alchemy is really not high, so. This technology will never serve the masses.

When the three of them left the alchemy workshop, even Bai Qi couldn't help but feel like he had seen the light of day again.

Alchemy is an extremely energy-consuming thing. The three of them plunged into this work, and they were busy for more than four years, and even Bai Qi couldn't stand it.

But this hard work is definitely worth it, not to mention the improvement of his skills, the value of the pile of materials in Bai Qi's hand alone can almost double or more!

You must know that Bai Qi has nearly a hundred middle-grade devils and demons in his hands, all the materials produced by nearly a hundred middle-level devils and demons, more than forty sets of devil equipment, and thousands of demonic iron refined from low-level devil equipment, and the total value of these things is almost nearly four thousand black evolution crystals. More than doubled, that's eight or nine thousand thousand black evolution crystals! Convert it into cyan evolution crystals, that's six or seven hundred!

Looking at these equipment, Bai Qi immediately decided to comprehensively improve the professional level of the back team.

When Bai Qi returned to the Golden Apple Bar with Barian and Qin Qing, the others were still waiting here.

Bai Qi had been busy in the alchemy workshop for more than four years, and for those who were waiting outside, it was just a few glasses of wine.

After Bai Qi took his seat, he took out a set of equipment. Hand it to everyone.

These equipment are all tailor-made for each person by Bai Qi, Barian and Qin Qing after their skills have matured, and if they are taken by others, it will be fine. But when worn on them, it can almost top the effect of half a set of cyan equipment.

After this exercise, Bai Qi's alchemy is also a masterpiece. A stronger alchemy rifle was designed.

The name of the rifle is also called "Bai Qi's Heavy Blow Shotgun".

Although the name has not changed, the appearance and performance of the new gun have changed a lot.

Two rifles designed by Bai Qi earlier. The exterior is similar to the old rifle, but this new gun is different. It looks weird.

The barrel of the new rifle is thick, several times thicker than that of a normal rifle, and the body of the gun looks thicker and bulkier.

The reason for such a change is that Bai Qi designed a multi-layer superposition method with a magic array attached to the barrel.

To put it bluntly, the magic arrays on the barrels of the alchemy rifles were all single-layered in the past, and the changes made by Bai Qi were nothing more than to make each magic circle occupy a shorter length.

The so-called multi-layer superposition method of the barrel with the magic array, to put it bluntly, is to make the appearance of the magic circle in two layers of magic circles, so that the number of magic circles arranged with the same length of gun barrel is three times more.

The appearance of the magic circle and the appearance of the magic circle are easy to say, but in fact it is not easy at all, otherwise it would not have waited for Bai Qi to invent it.

The difficulty of multi-layer circles lies in the fact that the multi-layer circles are arranged in the same area, and when the bullets pass, multiple circles must take effect at the same time, which needs to solve the mutual interference caused by multiple spells taking effect at the same time.

This problem is not easy to solve, and in order to solve this problem, Bai Qi and Barian have spent months researching and forgetting to sleep and eat, and finally solved it.

Their solution is to find a way to turn the three magic circles into a compound magic circle, so that each of them is enchanted independently and becomes a compound enchantment, and this three-dimensional attachment magic circle mode already has the shadow of a high-level magic circle.

Alchemy is a derivative of spells, and in turn, alchemy is another manifestation of spells, and through this research, Bai Qi and Barrian's understanding of magic has reached a higher level, and the two have even touched the doorway of high-level magic.

After the "multi-layer superposition method of the barrel with magic array", the "Bai Qi's heavy blow shotgun" is first of all the barrel kinetic energy addition increased significantly again, reaching 1500, and the additional armor-piercing technique has also reached the +4 level, because the initial velocity of the bullet is too high, so the air resistance of the bullet after the disembowel is also increased geometrically, in order to solve this problem, Bai Qi used alchemy to transform the seven-grade spell wind escape technique into a magic array, which was arranged at the front end of the barrel to solve the problem of bullet wind resistance.

Due to the thickening of the barrel, the ability of the barrel to withstand pressure has also increased significantly, and Bai Qi has deployed more powerful ammunition, which further increases the power of the bullet itself.

The rifles that have undergone this series of modifications have even surpassed the power of ordinary light cyan weapons.

When everyone got the tailor-made equipment, they were naturally amazed.

When everyone's excitement passed, Bai Qi took everyone to the auction house, rented an auction room, and took out nearly 300 pieces of equipment in the storage space.

Bai Qi pointed to this pile of equipment and said: "These equipment are the results of me and Barrian, Qin Qing, and more than four years, in addition to the equipment tailored for ourselves, the rest of these, even if they are sold cheaply, can be exchanged for six or seven thousand black evolution crystals." With so many resources, it's enough for our back team to move up a class level. (To be continued.) )
