Zhang Lan walked away after saying that.

Mo Tian smiled and then entered the cave.

With his hands stretched out, a wave of heat swept through, and the chill in the entire cave was immediately dispelled a lot.

"Fire Spirit Crystal!"

The iron-feathered giant eagle looked at the crystal in Mo Tian's hand in surprise.

The size of a thumb is fiery red all over, just like a solidified flame.

At this time, there were already signs of burning in Mo Tian's palm, but Mo Tian not only did not feel the pain, but could not help laughing.

"Senior, I exchanged it for spring water. Do you think it's worth it?" Mo Tian asked with a smile.

"value!"

The Iron Feathered Eagle nodded very simply.

"I feel it's worth it."

Mo Tian said as he took out the flying sword, and then put the fire spirit crystal on the sword.

Then this fire spirit crystal began to melt slowly and merge into the flying sword bit by bit.

After a period of time, the fire spirit crystal disappeared, but strands of flames began to rise on the surface of the flying sword, and finally completely wrapped the flying sword.

The flames disappeared, but some impurities appeared on the surface of the flying sword, and these impurities fell down one after another as the flying sword vibrated.

Mo Tian thought, and the flying sword began to grow bigger, and after reaching a certain level, it began to shrink again.

Then it becomes larger and smaller again.

More than a dozen times later, the flying sword turned into a beam of light and shadow, and then penetrated into Mo Tian's palm.

Refining a sword into the body.

Mo Tian finally did this.

The flying sword kept wandering in the body, but it blended with Mo Tian's bloodline. This experience is very strange. In Mo Tian's view, the flying sword is a part of his body.

"But now it is not considered a natal flying sword, and it still needs to be nourished with all your efforts." Mo Tian's heart moved, and the flying sword penetrated his body and turned into three inches in size and fell into Mo Tian's palm.

"A piece of fire spirit crystal has advanced the flying sword into a medium-grade spiritual weapon. With the fire power of the fire spirit crystal, it will be faster to melt other materials in the future." Mo Tian felt the changes of the flying sword carefully, and felt more and more joy in his heart.

"I wonder if the power can be comparable to the Blood Shadow Sword?" Mo Tian had such a thought.

However, Mo Tian quickly shook his head again. In terms of power alone, it is still not as powerful as the Blood Shadow Sword, but it is definitely more lethal than the Blood Shadow Sword when used to fight against the enemy.

"Do you want to go to the sword cultivation?" Tieyuki asked curiously.

"I can be considered a sword cultivator, but I have also practiced other things." Mo Tian thought for a while and said.
