During this process, Zhang Yifeng carefully took out the Sand of Time that had been extracted before and threw the Sand of Time into the furnace.

However, he did not put all the sand of time in it. After all, he extracted it from Yang Xiao's giant axe, so he left some for the other party.

Under the burning of a slight fire, the sand of time flowed into the melted refining material, emitting a light blue light.

About five minutes later, Zhang Yifeng used the object control technique again, took out the refining materials fused in the furnace from the inside, and placed them on the forging table.

Dangdangdang!

Zhang Yifeng once again used the meteor hammer technique. With his waving movement, the refining materials on the forging platform continued to change shapes, gradually forming the shape of the array flag.

"Now, it's time to carve into the formation."

As the medium for the formation master to arrange formations, the formation flag itself has formations inside, and its function is to absorb the spiritual energy of heaven and earth. Each formation flag echoes each other, forms a connection, and maintains the formation's long-term operation.

Zhang Yifeng is now an eighth-level formation master. It is not very difficult for him to carve formations on the formation flag. Not long after, he completed the formations in each formation flag.

"It's only the last step."

The formation flag is the most important equipment of the formation master and the prerequisite for them to successfully deploy the formation. If a formation master wants to better use the formation flag to arrange a powerful formation, he must strengthen communication with the formation flag.

The best way to strengthen communication is to integrate your own essence and blood into the array flag.

But the monk's essence and blood are only three drops, which are very precious. And every time he uses one drop, the monk himself will be greatly damaged. If there are no special means or secret methods, it will be difficult to recover.

The essence and blood cannot be recovered. Over time, the strength of the monk will undergo a serious regression, and even in serious cases, it will endanger life.

Most ordinary formation masters do not have a deep background and do not have a way to recover their essence and blood, so they rarely integrate their essence and blood into the formation flag, which invisibly greatly affects their strength in setting up formations and controlling the formations.

However, Zhang Yifeng did not have this worry, because he was not only a formation master, but also a alchemist. As the former Dan King, he could refine pills to quickly recover essence and blood, so the loss of a drop of essence and blood was not a big problem for him.

Taking a deep breath, Zhang Yifeng used the secret technique and forced a drop of essence and blood to merge the essence and blood into the array flag. The moment the essence and blood merged into the array flag, a feeling of blood being connected appeared in Zhang Yifeng's heart.

He had a feeling that he had just one thought, and the array flag could instantly arrange and arrange the array according to the array he had conceived in his mind, and his array speed would be several times that before, and this was not counted as the bonus of the Sand of Time.

At this time, Zhang Yifeng's eyes were gathered on the array flag, and he saw that the array flag was filled with light and several powerful energy fluctuations emanating from the array flag. The light blue lines on the array flag gave people a deep and cold feeling.

After picking up a flag of the array and checking, a smile appeared in Zhang Yifeng's eyes.

He thought that this time the upgrade of the array flag would only make the level of the array flag reach the level of the eighth-level weapon at most, but what he didn't expect was that perhaps because of the addition of Shi Zhisha, the array flag was actually upgraded to the level of the ninth-level weapon.

In other words, as long as his formation cultivation reaches level nine, he can use this array flag to arrange a level nine formation!

Thinking of the power of the ninth level formation, Zhang Yifeng felt a heat in his heart, but in an instant he came to his senses. Now his formation cultivation is only at the eighth level, and it is still a bit far away from the ninth level. The ninth level formation is not what he should consider now.

"The light blue flag body and most of the materials are obtained in the Netherworld, so let's call you the Nether Blue Flag."

The moment he thought, Zhang Yifeng named the array flag.

At this moment, Zhang Yifeng didn't know how big a nightmare the three words "小无王子" had brought to his enemies for a long time.

After putting the upgraded light blue flag into the storage ring, Zhang Yifeng looked at the refining materials he had decomposed on the shelf.

When he was outside, in order to get Shizhisha from the giant axe, he promised to help Yang Xiao upgrade the giant axe to a level nine weapon for free, so he naturally had to fulfill his promise.

Zhang Yifeng frowned when he placed the decomposed refining material on the forging table.

To upgrade the giant axe to a level nine weapon, he had several solutions in his mind, the most direct and effective one was to use the Soul Blood Forging Technique, thinking that his current mastery and understanding of the Meteor Hammer Technique could easily forge a level nine weapon as long as he used the Soul Blood Forging Technique.

However, to use the soul blood casting technique, the spirit of the beast must be added during the forging process, that is, the essence and blood of the beast.

Although his storage ring contains some beast blood, and the storage ring of Miaoshui Zhenren has very powerful beast blood, these beast blood must be used to upgrade the spirit of the Sky Strike, and cannot be used to forge giant axes.

Thinking of this, Zhang Yifeng made a decision in his mind, not to use the soul blood casting technique, but to use other methods to upgrade the giant axe to a level nine weapon.

"In addition to the two materials I just exchanged for in Zhenbao Pavilion, it should be OK."

Thinking of this, Zhang Yifeng calmed down and devoted himself to the work of forging a giant axe.

...

Just as Zhang Yifeng was concentrating on refining weapons, the Tie Family Refining Pavilion became lively.

Although there are people coming to the Tie Family Weapon Refining Pavilion on weekdays, there are not too many people coming. After all, the cultivators who come here either go to the Weapon Refining Pavilion to buy weapons and various refining materials, or ask the Tie Family's weapon refining masters to forge weapons for themselves. As for those who rent the refining room, most of them are some refining masters.

But no matter which type of person you are, it will cost a huge price to come to the weapon refining pavilion. In a short period of time, they simply cannot save enough capital to come here to squander it once.

But today, there were many monks gathered in the lobby on the first floor of the weapon refining pavilion, and even monks rushed in from outside the door one after another.

"Old Yang, I heard that a young man wanted to help you upgrade your giant axe to a level nine weapon. Isn't it true?" A new monk asked with a curious look on his face.

Before Yang Xiao could speak, a monk standing next to him said to the monk he had just asked: "Of course it's true. I was here just now. I heard what the young monk said with my own ears."

hiss!

Everyone around them felt a little incredible when they heard this.

Immediately afterwards, their eyes became sympathetic when they looked at Yang Xiao, and some people even began to speak sarcastic words.

"Hey, Lao Yang, you're confused. Your giant axe is a level 8 weapon no matter how you say it is. If it is forged by that young man, you will have no place to cry."

"Yes, although the level 8 weapon is not as good as the level 9 weapon, it is not cheap either."

Listening to the words of everyone around him, Yang Xiao's face became more and more gloomy.
Chapter completed!
