The Legend of the Immortal Cauldron

"Top-grade Biyun Stone."

After Matthew took out a fist-sized emerald green stone, he smiled with a smile on his face.

Biyun Stone has a wide range of uses, basically the same as Spirit Stone.

The good thing about Biyun Stone Wall Spirit Stone is that the Biyun Spiritual Qi inside it can assist in alchemy.

Top-grade Biyun Stone is a rare and precious thing.

After Matthew put away the piece in his hand, he immediately released the sword energy to continue cutting the nearby rock wall.

Soon, he found several more Biyun Stones.

One of them was also top-grade.

The elixir suitable for Yuanying Stage not only requires high-quality spiritual medicine.

Even the difficulty of refining is surprisingly high.

In the mysterious space, Matthew tried to refine some elixirs.

With his alchemy level, the success rate of refining these Yuanying Stage elixirs is only 10% to 20%.

If the Biyun Qi can be added, the success rate should be improved.

Since we have come here, and we have also discovered the existence of top-grade Biyun Stone.

Then Matthew would naturally collect more to prepare for his future alchemy.

This is the deepest part of the mine, and occasionally someone would come here.

Matthew was not worried about this, anyway, he was in an invisible state.

As long as someone came here, he would be knocked out immediately.

It took several days for Matthew to collect more than a dozen pieces of high-quality Biyun Stone and then quietly left this place.

This is not because he thinks that the collected Biyun Stone is enough.

But the high-quality Biyun Stone is really rare.

He has expanded the pit for hundreds of feet in the past few days to collect more than a dozen pieces.

He felt that it would be a waste of time to stay any longer, so he decided to leave decisively.

After coming out of this mine, Matthew did not rush to the place where the second fragment existed.

Instead, he followed the same method and sneaked into a mine next to it.

After searching inside, he only got five pieces of high-quality Biyun Stone.

Just when he was about to continue to the next mine.

He happened to see two Jindan monks counting Biyun Stone.

It is normal to count Biyun Stone.

But Matthew noticed that the two men secretly put some of the Biyun Stone into another storage bag.

Although the number of Biyun Stone stolen was not large.

But seeing that the storage bag was slightly bulging, there should be a lot of Biyun Stone stored in it.

Matthew cursed himself for being stupid.

He spent so much effort to mine Biyun Stone.

He didn't expect that there was ready-made Biyun Stone on it.

He didn't dare to rob those large quantities of Biyun Stone.

These were things that Tu Shen Temple valued very much. If he robbed them randomly, it might attract people from Tu Shen Temple.

However, it was different for the Biyun Stone that was secretly hidden.

Even if he robbed them, these Jindan monks would not dare to report it.

Otherwise, they would not be able to escape the charge of privately withholding Biyun Stone before sending people to investigate.

Thinking of this, Matthew's mouth curled up with a smile.

When the two Jindan monks counted the Biyun Stone, one of them flew away from the mine.

It seemed that he was going to go to Biyun City to deliver the Biyun Stone.

Matthew followed him all the way.

When the man in front of him was far away from the mine, Matthew flicked his finger.

A golden sword energy flashed out.

Because Matthew was invisible, the man in front of him didn't notice it at all.

The golden sword energy was extremely fast.

When the man found it, the golden sword energy had already pierced his shoulder.

With a scream, the man fell directly from the air.

Matthew moved his body and came to the unconscious Jindan monk, and took the hidden storage bag from his arms.

With a sweep of his spiritual sense, Matthew showed a smile on his face.

This storage bag contained hundreds of jade cloud stones.

Although there were no top-grade jade cloud stones.

But there were quite a few medium-grade ones.

It was also a big gain for him.

He did not kill this person, and left him here after taking the storage bag.

Then, another escape light flew out from the mine in the distance.

After the man flew out for a while, he was shot down by a golden sword light.

Matthew also looted a storage bag full of Biyun Stone from this man.

"These people all took their hidden storage bags to the city. It seems that they are not the only ones doing this. There should be someone in the city to support them."

After dealing with four people in succession, Matthew sat on a stone and murmured softly.

After waiting for a few days, he had to give up when he saw that no one left the mine.

These people are not fools. They dare not continue to come out when they know that someone specializes in robbing the hidden Biyun Stone.

Matthew also had more than a thousand pieces of Biyun Stone on him, which was somewhat satisfied.

After leaving this place, Matthew rushed to the location of the second fragment.

After circling around the light spot for several times, Matthew showed a puzzled look on his face.

"Ding Ling, where is the location of the fragment?" Matthew asked in a voice transmission.

He had searched here for several times, and even dived underground.

But he still couldn't find the location of the fragment.

"Master, it's in a stone brick under the city wall." Ding Ling reminded hurriedly.

"I see." Matthew suddenly realized.

His attention had been on other places, but he had not noticed the stone bricks.

After getting the exact location from Ding Ling, Matthew went underground again.
