"Time is secondary, and the Dead Daoist doesn't say when the Burial Sword Mountain will open."

Lin Yun said.

Then, Lin Yun took out the map and looked at his position.

"We've reached the edge of the central area, and the hard days are coming to an end."

Lin Yun said.

Looking at the sun that was gradually sinking in the west, Lin Yun breathed a sigh of relief and entered the Great Dao Stone Plate again.

At this time, Lin Yun had been staring at a picture for three or four days.

"Boy, if you want to cast a spirit stone cannon, I can tell you, the smallest one is the spirit stone cannon on the back of a beast-type puppet, it's too big, it's not easy to use, and the energy required is too great."

Bai Lao said.

"I know all of this, but I'm not looking at this one, but the latter one."

Lin Yun said.

"The latter one?"

Bai Lao leaned up and looked inside.

"Levitating Spirit Stone Cannon!"

Bai Lao said.

"That's right, this is it."

Lin Yun said.

"This can be driven by spirit spirits, or you can use high-grade spirit stones, I happen to have it here, and the casting difficulty of this is not small, on the casting material the size of half an arm, it is necessary to depict thousands of formations, including suspension arrays, attack arrays, energy transmission, and it also needs to cast thousands of materials combined, the difficulty is not ordinary.

And the attack effect is also good, one blow is equivalent to a full force blow of the nine layers of the quenching realm, although it is nothing, but this can also play a role in turning things around at a critical moment, and it also plays a role in the face of some cluster attacks of demon beasts, that is, a high-grade spirit stone can only be fired thirty times, and the spirit stone must be replaced, if there is a spirit crystal, it can be launched hundreds of times. ”

Lin Yun said.

"That's good, but is your casting technique okay? And these formations are very small, can your soul power do it? ”

Bai Lao asked.

"Bai Lao, I haven't left my soul power behind."

Lin Yun said.

Only then did Bai Lao realize that Lin Yun's soul power had already appeared a little orange.

"Since I had a soul soldier, every time he devoured my soul, he would give me some back, and after I refined, my soul power has increased by leaps and bounds."

Lin Yun said.

"You kid, how much else did you hide from me."

Bai Lao said.

"Don't dare, it's gone."

Lin Yun said.

Then, Lin Yun took out a piece of ore, sacrificed the spiritual fire and began to calcine.

"It's a pity that all the ores in Luofeng Mountain have been used to improve the Chixiao Sword, and there is not much left."

Lin Yun said.

Subsequently, the ore was quickly melted under the high temperature, and after removing the impurities, the solution was quickly formed under the control of Lin Yun's soul power, and the iron was struck while it was hot, and the formation pattern was quickly carved, and then put aside to cool, and then another piece was taken out and continued to be cast.

However, the difficulty of making the suspended spirit stone cannon surprised Lin Yun, and from then on, Lin Yun was in a hurry during the day and returned to the Great Avenue Stone Plate at night to make the suspended spirit stone cannon.

Tonight, Lin Yun carefully assembled the various parts of the suspended spirit stone cannon and put it into the spirit stone, and in an instant, the formation patterns on the suspended spirit stone cannon began to emit white light, and at the edge of the suspended spirit stone cannon, eight blue lights lit up, and then, the suspended spirit stone cannon slowly floated up.

"Levitation array, it's okay."

Lin Yun said.

But as soon as Lin Yun finished speaking, he found that a formation of the suspended spirit stone cannon had a spiritual energy accumulation.

Lin Yun didn't think about it, and directly threw the suspended spirit stone cannon out.

"Boom~"

The levitating spirit stone cannon exploded directly, blowing out a pit in the Great Dao Stone Plate.

Although Lin Yun was not injured, Bai Lao strictly forbade Lin Yun to experiment in the Great Dao Stone Plate again, and wanted to try to go to the outside for an interview, Lin Yun could only agree, and then, Lin Yun took out the ore again and forged it again.

In the next few days, in the center of the desert, there were always loud explosions from time to time.

Although the explosion was loud, because it was in the middle of the desert, no one paid attention to it, let alone looked at it.

"Ahem, failed again."

Next to a pit of black smoke, space distorted, and Lin Yun came out of the void.

"Go on, I still don't believe it, I can't build it myself."

Lin Yun looked at the few ores in the Great Dao Stone Plate and said.

Subsequently, Lin Yun continued to calcinate, while analyzing the reasons for the previous failure, summing up experience, and paying attention to the next time.

After several failures, Lin Yun's forging speed became faster and faster, and soon, another part of a suspended spirit stone cannon was cast.

"Last time, there was a problem here, last time was that the formation pattern depicted here was shallow, the aura did not pass, and the siltation here led to failure, and here was the time when the depiction was short, and the formation pattern was not connected."

Lin Yun recalled the reasons for his failure over and over again, and did not make the same mistake in the portrayal this time.

Finally, with the completion of the last formation pattern carving, this suspended spirit stone cannon was finally completed.

"Bless, you must succeed."

Lin Yun came outside and said.

Then, Lin Yun put the spirit stone inside, and soon, the formation pattern began to transmit spiritual energy, and the suspended spirit stone cannon began to slowly float into the air.

Lin Yun didn't have much of a problem with this step, but when he attacked, there was always a problem, causing the suspended spirit stone cannon to explode.

Lin Yun used his soul power to carefully control the levitating spirit stone cannon to move in the air, and after seeing that there were no problems with the levitating spirit stone cannon, Lin Yun used his soul power to activate a formation in the levitating spirit stone cannon.

In an instant, a white aura light appeared on the muzzle of the suspended spirit stone cannon, and the next moment, a pillar of aura light was launched directly from the muzzle.

"Boom~"

In an instant, sand splashed not far ahead, and a crater appeared there.

"Yes, it worked."

Lin Yun looked at the sand that had not yet fallen in front of him and said.

Subsequently, Lin Yun continued to control the attack of the levitating spirit stone cannon, and it was not until thirty rounds later that the spirit stone's aura was exhausted, and then the levitating spirit stone cannon was summoned.

"It's not easy to finally succeed."

Lin Yun looked at the suspended spirit stone cannon in his hand and said.

For a whole month, God knows how many times Lin Yun had failed, and now he finally succeeded.

"The next step is mass production."

Lin Yun said.

"Boy, that's a good idea, but it's definitely not going to work right now."

Bai Lao said.

"Well, uh, no."

Lin Yun turned around and just wanted to ask why, but when he turned around, he saw the ore that only two hands were left and understood.

"Forget it, just do as many as you can."

Lin Yun looked at the ore and said.

"The quality of these ores is not very good, so let's buy some better quality when you leave the desert."

Lin Yun said.

"Well, what's that?"

Lin Yun came out of the stone plate of the Great Dao, and was about to continue walking out when he saw a yellow line rushing towards this side in the distance.
