Leave Dingsheng Auction House.

Cao Chuan and Wen Jinghao chose to go back to Cold Moon Palace directly with Yu Qinglan.

Qingyun and Xiaoxi, the two little foxes, naturally also brought them.

It's just that when leaving, the group did not take a carriage or horse, but directly boarded the flying spirit boat of the Cold Moon Palace, which was already waiting outside the city.

The speed of the flying spirit boat is fast.

Even though the Cold Moon Palace was 108,000 miles away from Tai'an City, with the full strength of the elders of the Cold Moon Palace, it would only take less than a week to return to the Cold Moon Palace.

And on the way to the Cold Moon Palace.

Cao Chuan took out the bottle of essence blood that he had bought from the Dingsheng Auction House.

First, let Qingyun feel the power of the bloodline contained in the essence blood, and after confirming that this bottle of essence blood was indeed from the power of the ancient fox clan, he divided the whole bottle of essence blood into five points first.

Among them, the little fox swallowed two drops of essence blood, and Qingyun devoured three drops of essence blood.

After each swallowing the essence blood, the little fox and Qingyun entered a state of retreat together.

The speed of the flying spirit boat was also slowed down slightly, so that the retreat of Qingyun and Xiaoxi would not be affected by the many monks in the Cold Moon Palace.

Meanwhile.

Cao Chuan took out the mutilated spirit sword that was also auctioned at the Dingsheng Auction House.

Ren Xiaoyao had said before that this sword resonated with the Holy Spirit Sword Technique he had cultivated, so he felt that this mutilated Spirit Sword might be related to the original owner of the Holy Spirit Sword Technique, and he might even be able to get a glimpse of the opportunity to achieve the Wonderland.

Such an opportunity cannot be missed.

Cao Chuan immediately took this sword and began to operate the mental part of the Holy Spirit Sword Technique that he had obtained from the Lintian Pavilion before.

With the Holy Spirit Sword Technique's mental method began to work.

The mutilated spirit sword that Cao Chuan placed on his knee actually began to shake on its own, constantly touching Cao Chuan's body, as if it was coquettish and close.

At this time, Cao Chuan just stretched out his hand towards the Broken Spirit Sword, and saw that the Broken Spirit Sword flew up directly and ran into his hand.

In the next second, Cao Chuan felt that there seemed to be some kind of very mysterious connection between himself and this broken spirit sword.

It was as if the sword was originally part of his hand.

"Do you mean..."

"Is there a possibility that this mutilated spirit sword is actually an arm of the founder of the Holy Spirit Sword Technique?"

This thought suddenly popped up in his mind, and Cao Chuan suddenly scares himself awake with a spirit.

But after he came back to his senses, he found that the mutilated spirit sword he was still holding in his hand just now had disappeared at some point, as if it had never appeared.

Until Ren Xiaoyao's voice sounded again in the sea of knowledge.

I only heard Ren Xiaoyao use his slightly surprised tone to speak: "It seems that we all guessed wrong, this mutilated spirit sword is not a spiritual weapon, an immortal weapon, but a bone from the great power, and it may even be an arm bone that evolved into a long sword after breaking away from the great power." ”

"Otherwise, how could it directly fuse with your arm after you run the Spirit Sword Technique?"

"It seems that there are still many secrets about the Holy Spirit Sword Technique that are worth digging into."

"The senior who created the Holy Spirit Sword Technique must be a supreme being who has surpassed the Supreme Realm in the cultivation realm, or even beyond the immortal realm."

In the depths of the sea of knowledge, Ren Xiaoyao sighed at the power and mystery of the person who created the Holy Spirit Sword Technique.

And Cao Chuan had a whim.

"Since this mutilated spirit realm is actually an arm bone, it can evolve into the appearance of a sword weapon."

"Then can I use this arm bone as a sword weapon?"

"For example, use it to perform the Holy Spirit Sword Technique?"

Thinking of this, Cao Chuan immediately got up, and while recalling the moves of the Holy Spirit Sword Technique, he raised his right hand that had just fused the Broken Spirit Sword, pointed it at the sky in front of him, and then let out a loud shout.

"Holy Spirit Sword Qi!"

As soon as the words fell.

I saw that Cao Chuan's right hand that had fused with the mutilated spirit sword suddenly glowed with a burst of luster like spirit jade, and then a solid jade-white sword qi suddenly burst out towards the direction where his finger was pointing, leaving a series of spatial cracks in the air that were torn apart.

Eventually, there was a burst of bang in the air far away.

A fluctuation of spiritual power even affected the flight of the flying spirit boat.

"It's really doable!"

Seeing that the Holy Spirit Sword Qi that he used casually was so powerful, the smile on Cao Chuan's face could no longer be hidden.

But here it is.

Ren Xiaoyao suddenly shouted loudly in his sea of consciousness: "I advise you not to rely on that arm bone frequently to use the Holy Spirit Sword Technique. ”

"Why?" Cao Chuan suppressed the joy in his heart and asked rhetorically full of doubts.

"Naturally, because your right hand and that arm bone have not been completely fused, if you use the power of your arm bone to perform the Holy Spirit Sword Technique, it is very likely that the arm bone will detach, resulting in the tragic situation of your entire right arm being broken."

"What Ren seniors said is reasonable."

Cao Chuan has never been an anxious person.

After hearing Ren Xiaoyao's explanation, he thought it was true, so he temporarily abandoned the idea of trying other moves in the Holy Spirit Sword Technique, and instead returned to the deck of the Flying Spirit Boat and sat down, while asking Ren Xiaoyao how he could speed up the fusion of his arm bone and his right hand.

He wanted to know what kind of realm of the Holy Spirit Sword Technique he would be able to perform with his right hand once he was fully fused.

"There's a way to do this."

"Ready-made solution?" Cao Chuan raised his eyebrows, as if he had guessed what Ren Xiaoyao wanted to say.

Ren Xiaoyao didn't hide it, and said bluntly: "If you want to speed up the fusion of the arm bones with your right hand, you may be able to borrow those divine fire seeds from your dantian and burn your right hand and arm bones with their flames, so that your body and arm bones can be bathed in fire Nirvana, and then complete the fusion from the fire nirvana." ”

"In this way, the right hand and the arm bone can be fully integrated."

"Of course, the use of this method is bound to be accompanied by extreme pain and uncertain danger, and I would not recommend using this method unless you are completely sure."

"Is there any other way?" Cao Chuan frowned and continued to ask.

"I don't know."

Ren Xiaoyao replied very simply.

He really didn't know that there was any other way.

But he continued, "Maybe there will be a way you want in the Lintian Pavilion, but you may need to defeat me in the Dao Slashing Realm first. ”

This time, Cao Chuan didn't pay attention to Ren Xiaoyao anymore, but got up and walked to Yu Qinglan's room on the flying spirit boat.

Since he and Wen Jinghao had already planned to go back to Cold Moon Palace with Yu Qinglan, there was no need to continue to disguise their appearance.

He intends to show his true colors from today onwards.
