Xiao Changfeng was surprised. These purple crystals were extremely rare soul crystals.

Among the three treasures offered by Emperor Bai in exchange for the Nine Transformations of the True Dragon, there was a soul crystal.

But Bai Di has collected it for thousands of years.

I could only get three low-grade soul crystals.

And now in this treasure box.

There are a total of nineteen soul crystals.

And in addition to eighteen pieces of low-grade soul crystals.

The last piece.

It turned out to be a middle-grade soul crystal! The low-grade soul crystal was only the size of a fingernail, and it was only lavender.

The middle-grade soul crystal is about the size of a tea cup lid.

Purple light is also pure like water.

The soul power contained within it is also extremely abundant.

"Master, these are the treasures left by the old slave for thousands of years. The old slave is willing to dedicate them all!"

Wu Changsheng held the treasure box with both hands and spoke respectfully.

Although he is not strong.

But over ten thousand years, he also collected a lot of good things.

However, with Xiao Changfeng's current vision, he cannot see these things.

He even gave the high-grade holy artifacts, heavenly artifacts, etc. to his father.

Not to mention these.

"You keep these things yourself, but this soul crystal is useful to me. I will teach you an immortal method to compensate."

Xiao Changfeng said calmly.

These treasures were all accumulated bit by bit by Wu Changsheng.

Xiao Changfeng will not swallow it up.

However, this soul crystal can make his martial soul grow.

Therefore, Xiao Changfeng was not polite.

"Thank you, Master!"

Wu Changsheng was overjoyed when he heard this.

If all these treasures were taken out, he would naturally feel extremely distressed.

Now that Xiao Changfeng gave it back to him, how could he be unhappy?

As for the soul crystal.

He has no martial spirit and is of little use.

But in exchange for an immortal method, it is extremely important to him.

Whether it is immortal cultivation techniques or magical techniques, they are not accessible to ordinary people.

"Let's go, it's time to leave!"

Xiao Changfeng put the treasure box into the storage ring and was not in a hurry to teach the immortal magic.

It will take a long time to go to China, so there is no rush.

Wu Changsheng quickly put all the treasures in the treasure house into the storage ring.

So far this treasure house is empty.

The two walked along the passage and returned to the ground.

"Um?"

Xiao Changfeng suddenly frowned slightly.

And at this time.
Chapter completed!
