Your chance is good, now it's mine

Judging from the traces, the pangolin should have been buried here early.

He dug a small pit, and sure enough there were two thunder essences and a small wooden box lying quietly in it.

The Essence of Thunder, the best of the Mysterious Grade, is a treasure that can only appear in places where thunder-attribute minerals gather.

It can be used to create a perfect Dao platform, or to condense a perfect golden elixir.

Ling Xuan accepted the two lightning essences and opened the small wooden box.

Among them is the low-level defensive martial art "Four Sides Xuanmen".

He opened it and browsed it for a while, and he roughly understood the power of this martial skill.

There are four Taoist doors on all sides, a total of four floors.

With each level of cultivation, there will be more Taoism that can be condensed.

Completing the fourth floor, it can condense the four sides of the Taoist door at the same time to resist attacks.

The four-sided Xuanmen can be placed in four directions around the body to resist attacks from around.

It can also be stacked to resist attacks from the same direction.

It can be said to be flexible and changeable, and it is very useful.

Ling Xuan nodded in satisfaction, restored the small pit, and left quickly.

"Next, it's the Thunder Toad Demon Crystal and the Heavy Weapon Crystal Refining Technique."

"Xiao Fan's life panel shows that five days later, an elder from the inner door of the Heavy Equipment Sect sneaked into the Thunder Crystal Mine and came to the deepest part of the sixth tunnel to look for these two things."

Ling Xuan thought for a while.

He knew the situation of the Heavy Weapon Sect. Ten years ago, a traitor appeared in the Heavy Weapon Sect and stole the original "Heavy Weapon Crystal Alchemy". But nowhere to be found.

After that, with the death of a group of master craftsmen, the crystal refining technology of the Heavy Equipment Sect declined a lot.

Of course, even so, the Heavy Artifact Sect is the only sect in the vicinity that has a full set of spiritual weapon punching and inlaying techniques, and it still makes a lot of money.

"Maybe, this elder came to the Thunder Crystal Mine to look for it because he knew something about it."

"It's just that the protective formation is always on. How did he sneak in quietly? How did he escape with serious injuries? Someone betrayed the information?"

Ling Xuan immediately thought of Liu Yuanfeng.

Don't think about it, if someone in Qingxuanmen betrayed relevant information, it must be Liu Yuanfeng.

"Ignore the matter of betraying the information, the Thunder Chan crystallization and the heavy weapon crystallization technique must be held in hand."

"In addition, according to the normal situation, the elder of the inner sect of the heavy weapon sect was severely injured and finally escaped."

"However, since I know how the incident develops, it is naturally impossible for him to escape."

Ling Xuan smiled faintly, "Since you dare to come, then leave him here!"

Chapter 81 Thunderbolt Sword Promoted to the Best of Mysterious Rank

Ling Xuan left the third tunnel and went straight to the deepest part of the sixth tunnel.

He patrolled around here, summoned his spiritual power to search, and soon found the place where two things were buried.

These two things are hidden quite deep.

And there are no signs of digging anytime soon.

If Ling Xuan hadn't been able to see the life panel, if he searched carefully here, he would definitely not be able to find it.

At the bottom of the pit, there were two things lying quietly at this moment.

One is the size of a palm, shining brightly and bursting with thunder.

The other thing was actually a book made of metal!

No wonder it has not decayed after many years.

Ling Xuan had already made preparations.

Putting on the gloves, he took away the Thunder Toad Demon Crystal unscathed.

After all, this monster crystal was left after the death of a fifth-order monster, and it contained extremely powerful thunder attribute power.

Xiao Fan's life panel showed that the alchemy-level elder of the Heavy Weapon Sect just didn't pay attention, and directly touched it with his hands, which caused serious injuries.

Then, there was a thunderbolt here, which caused the formation to throb again.

Even more wounded.

In the end, it was only by relying on the loopholes in the formation that they could escape by luck.

After Ling Xuan put away the Thunder Chan crystal, he picked up the heavy metal book.

After wiping off the dirt on the surface, the words "heavy weapon crystal refining" were engraved on the cover.

"With this thing, I can punch holes for the spiritual weapon and embed demon crystals myself."

"This is the gatekeeping skill of the Heavy Equipment Sect, and now I have it so easily."

Ling Xuan smiled, took his things and left to return.

Back in his room, he immediately began to read through the Heavy Weapon Crystal Alchemy.

After about an hour, he looked up from the book.

"So that's the case. The method of punching holes in the crystal refining technique of heavy weapons is very ingenious, and requires the use of special materials to make hammer chisels."

"This hammer chisel must be stable enough to punch holes without damaging the spirit weapon."

"Therefore, a variety of materials are needed to make a hammer chisel, and Lei Jing is one of them. No wonder the Heavy Equipment Sect has been occupying the Lei Jing mine before."

"As for the inlay, we need a kind of inlay liquid, which can be injected into the hole so that the demon crystal and the spirit weapon will not repel each other, so that the demon crystal can be inlaid perfectly."

"Hammer chisel and inlay fluid are the foundation of heavy weapon crystal refining!"

Ling Xuan nodded slightly.

Get ready, let's get started!

The Thunder Crystal Mine not only has Thunder Crystal, but also some associated ores, among which Ling Xuan needs.

Two days later, he got a pair of hammer chisels and a jar of mounting fluid.

Ling Xuan took out some yellow-rank spiritual weapons and some second-rank demon crystals.

According to the method of crystal refining with heavy tools, the holes are drilled with a hammer and chisel.

Then apply the mounting fluid and proceed with the mounting.

This process requires concentration, and a little carelessness will fail.

Ling Xuan also failed at the beginning.

But after all, he has taken Wuxing Pill and Great Wuxing Pill, and his understanding is far beyond that of ordinary people.

After failing a few times, I clearly understood my mistake.

Every time it gets better and better.

Ling Xuan felt that it was safe, so he took out the Thunderbolt Sword, and followed the previous procedure again.

Finally, he put on the gloves, took out a third-order demon crystal and embedded it in.

This monster crystal comes from the third-order monster, the fire ape, which is a monster that can breathe flames.

The Jinglei Sword is a mysterious spiritual tool, which cannot withstand too strong demon crystals.

The third-order demon crystal is the limit.

As for the fifth-order Thunder Toad Demon Crystal, Ling Xuan planned to drill and inlay it after he got a stronger spiritual weapon.

A moment later, a strange splendor wrapped around the Thunderbolt Sword.

Ling Xuan tightly grasped the hilt of the Jinglei Sword.

Immediately felt the meaning of joy coming from it.

Obviously, the trace of spirituality in the sword has also been felt, and he is becoming stronger.

Ling Xuan nodded slightly.

After inlaid with this fiery ape's monster crystal, the Jinglei Sword has reached the top grade of Xuan rank.

"In the heavy equipment crystal refining technique, the formulas of four kinds of hammers and chisels and four kinds of inlay fluids are recorded. This is the most important thing."

"I have this technique in mind, there is no need to keep it, it can be handed over to Nangong Yun."

Of course, Ling Xuan didn't intend to hand over all the heavy equipment crystal refining techniques.

In the world, only oneself is the most trustworthy.

Therefore, the best things, that is, the formulas of the best hammer chisel and the best mounting fluid, must be kept in one's own hands.

As for the others, they can all be handed over, there is no need to hide them.

Ling Xuan knocked lightly on the door.

Because he is the master of the young sect, there are always two inner disciples with strong strength guarding his gate.

Many people are scrambling to do this job.

When the two disciples heard the voice, they immediately responded, "Young sect master, what are your orders?"

Ling Xuan, "Please invite Elder Li to come over, just say that I have something important to discuss with her."

The two disciples nodded repeatedly, "Yes!"

After a while, Elder Li, who looked a little tired, came to Ling Xuan's room.

"Young sect master, why do you want me to come here?" Elder Li asked doubtfully.

Ling Xuan never bothered them much, but she was a little surprised to make this request suddenly today.

Ling Xuan smiled, "A few days ago, I chased a monster, entered the depths of the mine, and found this thing by accident."

"Elder Li will definitely be very interested."

He showed the metal book in front of Elder Li.
