In Su Yuelong's refining room, many boxes were neatly placed.

On each chest, there is a good classification, and different refining materials are classified and stacked.

The box was refined by Su Yuelong himself, and it was put on a special lock, for example, Lin Nan and others were opening it now, and it was locked with water attribute spiritual power, once the lock was unlocked in the wrong way, it would cause the materials inside to be flooded.

At that time, when refining these locks, she was addicted to it for a while, Su Yuelong had refined hundreds of locks, and when Lan Luo came in just now, Lin Nan was helping her recall the unlocking method of this box.

After some fiddling, I finally opened the box, and a box full of lava stones was neatly arranged inside.

As a seventh-grade refiner, there were still so many low-grade materials left, Lin Nan really didn't expect that after all, lava stone was only a second-grade refining material, and it could be used when refining treasure weapons.

After the two of them discussed the refining theory just now, they were ready to use their actions to verify their ideas, and Su Yuelong said that he had a lot of low-level materials, so many that he couldn't fit them in the Qiankun bag, and the refining materials below the fifth grade were all packed and placed in the refining room, as well as in the specially prepared warehouse in the Yuelong Court.

Lan Luo's refining cultivation is not low, he is already a fourth-grade refiner, and it can be said that Su Yuelong has taught well.

The refining of the lower grade treasure is very simple, and the three of them started work at the same time, but fortunately, the refining room is large enough, and the three refining furnaces are placed in the middle, so they don't feel crowded.

Su Yuelong's new refining concept, Lan Luo is also in contact with it for the first time, and when Su Yuelong was refining this combined flying sword, Lan Luo also happened to go out, and Lin Nan also came here today after asking Lan Luo's return time, saying that there was something to negotiate, but he didn't expect to be cut off by Su Yuelong.

Anyway, things are not in a hurry, so I will learn from Su Yuelong first, when Su Yuelong explained to Lan Luo the refining method of this combination of magic weapons, Lin Nan also re-studied it next to him, and learned the new from the past, and Lin Nan really discovered the loopholes discussed by the two before, and after studying it again, he directly started to practice.

Based on Su Yuelong's flying sword, Lin Nan also refined a sword hilt and a sword body, and engraved runes, held the finished treasure weapon in his hand, and fixed the sword body into the hilt.

With the combination of the two treasures, the momentum of the magic weapon rose rapidly, and finally with a "bang", it was directly blown up, if it wasn't for Lin Nan looking wrong and releasing a spiritual energy package, the power of this explosion was still a little powerful, even the Jindan monk could be injured.

Lin Nan suddenly felt that he seemed to have inadvertently refined something incredible, as long as the two magic weapons were refined into a cylindrical shape, and when the time came, a combination would be thrown directly towards the opposite side, is this a Xiuzhen version of a grenade?

Lin Nan's movements on this side naturally affected Su Yuelong and Lan Luo, glancing at Lin Nan, Lan Luo's right hand was still attached to the refining furnace, and he was a little surprised by Lin Nan's speed of refining magic weapons, and at the same time refining the lower grade treasure weapons, Lin Nan was actually faster than the master.

Su Yuelong is a seventh-grade refiner, all along, Lan Luo has not encountered a refiner who can compete with his master in refining, of course, it is in the green domain, and now, not to mention anything else, just talking about the speed of refining, Lin Nan will win, after all, Su Yuelong's low-grade treasure has just been baked, and Lan Luo himself has just finalized the magic weapon and is preparing to depict the runes.

Lin Nan's failure did not touch the two of them much, after all, the invention of a new thing is accompanied by countless failures.

The hilt of the sword in his hand and the body of the sword were closed, and there was no change, Su Yuelong's face was expressionless, and he casually put the magic weapon aside, and took out the materials again for refining.

Lin Nan et al.'s plan is to first ensure that the combination of inferior treasures can reach a certain standard with a success rate, such as more than eighty percent, of course, it would be better to be able to understand the rules of the combination.

Taking out a small notebook, Lin Nan recorded the first test, although it failed in the end, but it was able to make a reference, it was obviously the same rune, and even the shape and material were exactly the same, the reason for the failure still needed to be explored.

As Lin Nan and Su Yuelong restarted the refining furnace, Lan Luo finally refined his low-grade treasure.

The whole process of refining this combined magic weapon is not much different from refining a magic weapon, and all materials need to be born in the same refining process.

For example, this combination of flying swords originally meant to refine a flying sword, but at the final stage of forming, it was necessary to divide the materials in the refining furnace into two parts, one to form the hilt and the other to form the sword body, and to depict the runes respectively.

This is the experience that Su Yuelong has gained after countless attempts, doing so will greatly reduce the probability of explosion, Lin Nan exploded the first time, it was purely a bad character.

Combining the sword body and sword hilt in his hand, with the climbing of the spiritual power of the magic weapon, it finally stabilized to the level of a medium-grade treasure weapon, Lan Luo's first time, actually succeeded.

Looking at the combination magic weapon in his hand, Lan Luo seemed to have returned to the joy when he had just learned to refine the weapon and successfully refined the first lower-grade treasure flying sword, you see, the master and Lin Nan both failed, and he actually succeeded at one time, this sense of accomplishment is really satisfying.

After several attempts in a row, Lin Nan and Su Yuelong invariably stopped the movements in their hands and looked at the four magic weapons visiting by Lan Luo's side, what is the situation, Lan Luo's success rate has reached 100%?

Yes, Lin Nan and Su Yuelong's successive failures in exchange for Lan Luo's full success, so far, Lin Nan and Su Yuelong have each tried seven times, Lin Nan has also made seven grenades, and Su Yuelong's seven combination magic weapons are lying quietly aside, without any movement.

Only Lan Luo has never failed, and he still changes the combination of tricks, after the first two flying swords were successfully combined, Lan Luo tried to replace the runes on the treasure weapon, and refined a war hammer and a dagger.

Looking at the two freshly baked magic weapons, Lan Luo confidently reached out and grabbed it, and an axe was successfully upgraded to a medium-grade magic weapon, are you going against the sky, and you have succeeded again?

Lin Nan and Su Yuelong agreed that there must be something wrong that led to such a huge difference, after all, even the inventor of the combination magic weapon, Su Yuelong, only succeeded once.

"Let's stop for a moment and see if there's a difference in the details. ”

At Su Yuelong's suggestion, Lan Luo also stopped refining her own weapons, although she already wanted to try the combination of medium-grade treasure weapons.

"So you came to Haotianfu to find me, what is the matter?"

After all, stopping the refining in advance is not a problem that can be solved overnight, Lan Luo asked directly.

"What happened to the explosion of the dragon vein passage last time?"

"The Qingyu wanted warrant hasn't been canceled yet. ”

Lan Luo pursed his lips and said a little unpleasantly.

"It's good that it's not canceled, I just want to ask you, are you interested in blowing it up again?"

As soon as Lin Nan's words fell, the door of Su Yuelong's refining room was pushed open, and the sect master of Haotian Mansion stood outside the door with a serious face.

I can't pretend I didn't hear that. ”
