Guyao Mountain is not a mountain, but a small mountain range, with many peaks, and many places are not rich in aura, and it is also a so-called no-man's land. In a certain no-man's land, Ye Feng kept his knees cross-legged and closed his eyes. However, he was not meditating, but studying the formation, thinking about how to refine a set of equipment for himself.

Ye Feng had refined a lot of treasures, if it was an ordinary material, I am afraid that he would have opened the furnace to refine it a long time ago, but the Sanyan Red Refining Stone and the Yuanji Broken Gold were not ordinary things after all. Ye Feng didn't want to refine too casually, and he didn't want to wait until one day to refine his weapon strength to go one step further, and return the treasures he had refined before to the furnace for retraining.

The weapon has been following him, and after a long time, he will naturally have deeper feelings and tacit understanding of battle. This feeling of being a comrade-in-arms fighting side by side is not something that you can maintain by refining an identical treasure again. Therefore, this time, Ye Feng wanted to use this most precious material to refine a set of equipment that could always follow him. Even if his strength increases in the future, and the level of refining weapons also increases, this equipment can still follow him.

Ye Feng was still thinking, and even refined a lot of ordinary materials, all of which were experimenting with his own ideas. Experimenting again and again, thinking over and over again, and repeating the process of learning, in this process, Ye Feng integrated his comprehension and innovation into it, and formed his own set of formations, such as the density of the soul exploration materials, the degree of grasp of the fire, with them, the power of the weapons refined by Ye Feng was higher than that of the same level, and in the auxiliary perception of the supreme formation of the Heaven Dou Star Great Array, Ye Feng finally created a new refining technique - upgrading the alchemy technique.

As the name suggests, after an ordinary weapon is refined, it is what level it is, but Ye Feng can use his own method to make the weapon have the potential to be upgraded.

The main difference between different levels of treasures is that in the formation between the two, the formation level feels the treasure level. It is already remarkable for ordinary people to lay out a Six Tribulation Formation, but Ye Feng can not only lay out a Six Tribulation Formation, but also make this Six Tribulation Formation slightly changed to become a Seven Tribulation or even Eight Tribulation Formation, so that as long as it changes, the level of the entire weapon will be one level higher.

It must be known that the formation is an extremely cautious thing, the slightest deviation will be wasted, the more advanced the more so, if you want to make the formation not only successful, but also have the potential to upgrade, this must be built on a solid foundation of the formation, I am afraid that no one in the world can learn it, because no one has the foundation of the formation of the Heaven Dou Xingchen Great Formation like Ye Feng.

The Heaven Dou Star Great Array is the supreme formation that ranks second among the top ten divine arrays. It can be called one of the origins of thousands of formations. The real Heaven Dou Star Great Array was completed with the Ninety-Nine Eighty-One Star Array. When Ye Feng's strength was weak, he could only deploy it with a seven-seven-forty-nine star array. No matter how strong the strength is, it is also a fifty-four star array, and now it is only the strength of a fifty-nine star array. But with each increase, the power skyrockets. Based on the Heaven Dou Star Great Array, other formations are not like this, with the changes again and again, upgraded again and again, and applied to the refining weapon, the higher the formation level in the treasure, the higher the treasure level. This is the Upgrading Alchemy.

The theory is completely feasible, but there are still many problems in practice, so Ye Feng is also trying to use ordinary materials over and over again. Summarize over and over again.

The ordinary stones of the Nine Realms Venerable Realm were all huge treasures that could refine high-level pseudo-heavenly artifacts in other worlds, so Ye Feng could be said to have endless refining materials for experiments. After refining again and again, Ye Feng even finished refining a mountain, and in the end, Ye Feng, who had no refining materials, could only destroy the treasures he had worked so hard to refine, take out the materials and refine them again.

At first, Ye Feng used the primary formation to refine all kinds of low-level weapons, and then tried to upgrade these weapons, and succeeded less than one percent, but if there is success, it means that this idea is feasible, and the only uncertainty is that the key Ye Feng has not really grasped it.

Later, with the accumulation of experience, Ye Feng finally found the key point of grasp, and the success rate continued to improve. Zhizhi was almost 100% successful, and only then did Ye Feng open the furnace to refine the real weapon that belonged to him.

The giant treasures refined with the Sanyan Red Refining Stone and the Yuanji Broken Gold as the materials, each of these treasures Ye Feng comprehended every step of its refining with his soul, ensuring that every moment of refining reached the point of perfection, but the soul of the refiner himself also had to bear the pain of being tortured by the fire refining, and in order to refine them, Ye Feng endured great torture.

There are four pieces in total, and each one is a treasure that can be upgraded. The levels were all the highest level that Ye Feng could refine now, the Six Tribulation Pseudo-Heavenly Artifact.

A Six Tribulation Pseudo-Heavenly Artifact Defensive Battle Armor was completely refined by Yuan Ji Broken Gold. Yuanji broken gold is extremely soft, and it can be said to be extremely comfortable to wear on the body like silk. Not only is it invulnerable to fire and water, but it will not hinder the Heavenly Cultivators' combat effectiveness in the slightest. With the help of the formation, this armor can reduce the opponent's physical attack damage by 30% and the opponent's aura attack by 50%, which is definitely an excellent armor. The most important thing is that Ye Feng doesn't have to worry that this battle armor will be shattered, and the Yuan Pole Broken Gold, even the Six Realms Saint Heavenly Lord may not be able to destroy it. Ye Feng named this battle armor "Tianyuan Battle Armor".

The other is a long sword that is completely refined from the Three Flames Red Refining Stone, the long sword is very similar to the original Heavenly Relic Sword, but the level is higher, the power is greater, and the materials are not the same. With the help of the formation, this sword is enough to exert nearly twice its attack power, and the power of the ultimate is increased several times. Ye Feng also deliberately fused the golden sword to one and other ultimate moves with this sword, and in the future, with the help of this sword, the golden sword and the Jinmu Xunfeng and other tricks were enough to exert two to three times the power!

The third piece is a pair of combat boots, the sole of the boot is a fusion material of Sanyan Red Refining Stone and Yuanji Broken Gold, and the soft and hard are almost the same as the bottom of ordinary shoes. The body of the boot is extremely soft Yuan Ji Broken Gold, but the boot head is a hard Sanyan Red Refining Stone. Not only is it extremely comfortable to wear, but it is also enough to increase its speed by twice the speed, and the boot relies on the power of the boot toe, which is also a weapon for melee attacks. Especially when it comes to casting the Aeolus legs.

The last one is a space ring, although this space ring is refined by the precious Sanyan Red Refining Stone, it only has a simple storage function, except for a larger storage space and a more reasonable layout, there is nothing to say.
