Follow Zhagu to the depths of the castle, and walked down, walking a thousand feet away, then suddenly came to a huge cave.

The heat waves hit my face.

Yang Kai looked at him and suddenly showed an unexpected look, because there was a natural earth fire surging in this underground cave, and the omnipresent heat wave was caused by the earth fire.

There are also traces of human bans in this cave, and the entire cave is surrounded by a large array.

The place where the earth fire gathers is the center of the formation.

There are also some miscellaneous materials placed around the cave, and many of them look like they have been used.

Yang Kai frowned, revealing a confused look.

Zhagu went straight towards the center of the formation. The breath of the living creature seemed to activate the power of the formation. The earth fire that was enough to melt gold and jade to suck the flames at Zhagu. Zhagu ignored it and activated the power of ink to cover the big hand, reaching out to grab the earth fire.

After his big hand was pulled out of the earth fire, something was already added on his hand.

Zagu withdraws from the center of the formation and throws the thing in his hand to Yang Kai: "Look at this."

Yang Kai reached out to catch it, his arms sank slightly, and with his brute force, it shows how much weight this thing is.

This was a big suppress, about five feet long and as thick as a human leg. It seemed a bit inappropriate when Yang Kai held the big suppress in his hand, but this thing was obviously complementary to Zagu's body shape.

"This is..." Yang Kai looked at the halberd in surprise. With his divine sense, he quickly gained some insight: "The human race's weapon refining object?"

Turning his head and looking at Zagu in surprise: "Where does this thing come from?"

With his eyesight, it can naturally be seen that although this halberd was made by the human weapon refiner, it was not completely refined. It only had some prototypes roughly. Such things could not play a role on the battlefield. Under the power of the human race's Kaitian Realm, it would be easily destroyed.

"I originally had a Mo Tutor under my command. That guy knew a little about refining weapons. He spent a lot of time and resources to refine this thing for me."

Yang Kai was stunned, but he didn't expect it to be like this.

"The reason I placed my residence here is because of his suggestion. There is the earth fire he needs to refine weapons here, so that he can use his strengths. Unfortunately, before he can refine this thing... But before he left, he left a arrangement and told me to put it in the earth fire to warm it up, and it may be available in a hundred years."

Yang Kai shook his head and said, "It's useless, the foundation is not enough, no matter how warm you are, it's hard to become a climate."

Zhagu raised his eyebrows: "How do you say this?"

Yang Kai said: "I don't know what level of your Mo Tu's weapon refining technique is, but in my opinion, the refining technique is too rough. This secret treasure has been established from the foundation. Even if it is successfully nourished in a hundred years, all you get is just a low-grade secret treasure."

Zagu's eyes shimmered slightly: "So, your refining skills are higher than him?"

Yang Kai smiled proudly: "That's natural."

Zagu couldn't help but be excited: "If you take action, what kind of thing can you refine?"

Yang Kai pondered for a moment: "The secret treasures used in the Kaitian Realm of the Human Race are generally divided into three grades: upper, middle and lower levels, corresponding to the three grades: upper, middle and lower levels of the Human Race. All those who can refine top-grade secret treasures are master-level weapon refiners. My weapon refining skills are sloppy, far from the master, but it is still okay to refine middle-grade."

The one who practiced hard in weapon refining for ten years and taught him that he was also from the Divine Ding Cave Heaven.

This person is the six disciples of Dongguo Anping. Although his skill in refining skills is not as exquisite as that of Dongguo Anping, he is also at the level of a master. Such a person personally teaches him that even if his qualifications are poor, he can still grow in ten years of hard work.

What's more, many ways of refining weapons and alchemy are common. Yang Kai himself is still the seventh-grade Kaitian and has a good understanding. During that ten years, he followed Zhang Hao to practice refining weapons. His skills can be said to be a thousand miles a day.

Now his level in the art of refining weapons is somewhat considered to be in the hall.

However, Yang Kai is destined to achieve much in the art of refining weapons. Perhaps one day in the future, he will be able to grow to the level of refining top-grade secret treasures, that is, the level of a master. But that is his limit, a limit that he cannot break through in his entire life, and he will never be able to become a master like Dong Guo Anping.

He studied under the Divine Ding Cave Heaven, not to mention Yang Kai's current level of refining weapons, his eyesight alone is no longer comparable to ordinary refiners. In his eyes, the various crude aspects of this halberd are clearly visible.

However, Yang Kai did not expect that there was a weapon refiner under Zhagu's command. However, judging from the refining techniques of the halberd, the level of this weapon refiner is really not very good. Moreover, since I haven't seen it now, I think it has fallen on the battlefield. Fortunately, the weapon refiner has arranged some arrangements in advance and placed the halberd in the earth fire to slowly nourish it. In a hundred years, Zhagu can also get a low-grade secret treasure of the Heaven-Level Treasure.

However, with his lord-level cultivation level, activate a low-grade secret treasure on the battlefield, which is really helping his own combat power.

On the other side, Zagu's expression was obviously even more excited: "Don't lie to me."

Yang Kai sneered: "What a lie to you!"

"It's no point to say that you can make a spell for me as this secret treasure. All the materials are provided by me. If it can be successful, the Lord will thank you very much."

"It's easy to say." Yang Kai agreed. His purpose for coming here was to do this, but he didn't expect that things would go so smoothly.

Moreover, there is already a suitable environment for the weapon refiner here, and it can be said that he also inherited the legacy of the Mo Tu weapon refiner under Zhagu's command.

Taking caressing the phlegm in his hand, Yang Kai looked up and down for a while and said, "It would be too wasteful to refine it. Although this method of refining this thing is a bit rough, it has been formed. The materials used are very precious, and you just need to refine it."

"What do I need? I'll prepare." Zagu was very excited.

Yang Kai said: "Some supplies for restoration of practice."

"Just this?" Zhagu was a little surprised.

Yang Kai nodded.

This is nothing difficult, Zhagu quickly fiddled out a space ring and handed it to Yang Kai: "Let's see if these are enough?"

Yang Kai took it and saw that there were a lot of Kaitian Pills in the ring, as well as several sets of fifth-grade sixth-grade supplies.

The sources of the materials of the fifth and sixth grades cannot be verified, but only the Kaitian Dan can be refined by the human race, and it is only useful to the human race. Zhagu has it in his hands, which is obviously a spoil collected from the battlefield.

Judging from the number of Kaitian Pills, there are a few human soldiers who died at Zagu’s hands.

Yang Kai looked calm, put away the space ring, looked at the big formation in the cave again, turned to look at Zagu: "Where is the control array card for the big formation here?"

Zagu slapped his head: "Forgot!"

As he said this, he threw a formation card over, Yang Kai took it, and activated the power to refine it.

It is not difficult to refine this thing. It has been completely refined after only a dozen breaths. Holding this token, the formation here can be controlled and activated by Yang Kai.

This is of great help to refining weapons. After all, with the help of the power of earth fire here, refining weapons can achieve twice the result with half the effort.

Everything was ready, Yang Kai reached out and grabbed it in the void, and a silver light flashed, and something like an iron hammer appeared on the palm of his hand.

The iron hammer is given to him by Zhang Hao. This is also something that Zhang Hao used to refine weapons in the early years, but later he had a better one and stopped using it. He also saw that Yang Kai had some qualifications in refining weapons, and he was eager to study, so he gave it to him, otherwise how could he give it to him?

This thing is useless to him now, but after all, it is a witness to growth and has special significance.

Although it is useless to Zhang Hao, it is a good thing for Yang Kai. With his current level of refining weapons, he can only barely activate part of the power of the hammer, so he can't use better refining objects.

Yang Kai slapped the horde of heavy weight and inserted it into the ground and stood up straight.

While watching, Zhagu saw him swing the sledgehammer in his hand towards the halberd and smashed it hard.

When the sledgehammer was swung, the power of earth fire that was permeating the cave was frantically pouring into the sledgehammer, making the entire sledgehammer turn red.

There was a bang, and it was shocking.

Such an attack should have destroyed the entire cave, but the bizarre thing is that all the power is added to the halberd, without any spare force to escape. This is obviously because Yang Kai's control over his own power has reached its peak and he has not given any waste of his own power.

This move alone made Zhagu brow look up. The lord and the seventh-grade Kaitian are essentially the same level, but he can't control this move.

From this we can see that the gap between himself and Yang Kai is no wonder that the Mo army that others can kill has suffered heavy losses.

However, the scene in front of him made him extremely confused.

When the Mo Tu under his command was refining weapons, he had also watched from the side. Although he didn't understand the method of refining weapons, the Mo Tu's technique was exquisite and beautiful, and extremely mysterious. But Yang Kai was so rough and clumsy, and it looked like... a iron-smashing?

I was puzzled and heard another banging sound.

One after another, continuous, Yang Kai seemed to have used all his strength every time he waved the sledgehammer in his hand, and the rhythm between each hammer was clear, not bad at all. Every time he waved the sledgehammer, it triggered the power of the earth fire of the formation, and the iron hammer in his hand was red and hot.

With such a loud sound, eighty-one consecutive sounds, a large escalator was hammered from the beginning to the end by Yang Kai.

At first, Zhagu didn't notice anything, but as time passed, he clearly felt that the phlegm, which had only a prototype, seemed to have changed slightly, but this change was a bit indescribable, and he didn't know if it was his own illusion.

After eighty-one hammers, Yang Kai's aura was obviously a little unstable.

Immediately, I took out a large handful of Kaitian Pills to swallow.
Chapter completed!
