Mortal blood!

Lin Fan seemed to have a normal expression, but the spiritual power in his body was secretly activated.

This made Cui Yu, who had just had the idea of ​​killing someone and seizing the treasure, calm down instantly.

"Friend Dao Lin, you are worrying too much. I, Cui Yu, am also a man of my word. Just take these two formations with you," Cui Yu said.

Lin Fan nodded and cautiously exited the small courtyard.

Only when he left Liuyun City in one breath and made sure that no one was following him did he feel a little relieved.

"It's so dangerous. Cui Yu just had the idea of ​​killing people and seizing the treasure. Why did he suddenly change his mind at the last moment? However, I have to leave Liuyun City now to avoid being spotted."

Lin Fan felt lingering fear.

This time, he took the risk to meet Cui Yu, even though he took a huge risk.

But the harvest is also great.

Not only did he take away two sets of high-quality protective formations in vain, but he also obtained a lot of defective source power.

After bringing it back to his cave, Lin Fan only needed to seize the time to strengthen it so that he could use it to improve the level of the "Five Elements Chaos Sword Art".

This is the biggest gain for Lin Fan right now.

"I made a profit this time. I have to be more careful in the future."

Lin Fan muttered, and after getting out of the forbidden air range, he set up the Wind Controlling Divine Boat and fired directly in the direction of Qixuanmen.

Little did he know that just when Lin Fan left Cui Yu's courtyard, the Lihuo jackdaw that had fallen on the tree suddenly spoke.

"Fellow Daoist Cui, you were really reckless just now. For the sake of just two sets of high-quality formations, you actually had the idea of ​​killing people and seizing treasures. It's really not worth it."

Cui Yu couldn't help but look embarrassed when he heard this.

Then, he quickly said: "Senior Lihuo, I have followed you to learn how to refine formations over the years. I finally refined two sets of high-quality formations with my own hands, but they were both picked away by someone named Lin. I really can't help it. Be willing to do so.”

"Hmph, a little impatience will mess up a big plan. We have been lurking in Liuyun City for so long, so we don't want to be exposed at the last moment. If it ruins our big thing, can you afford it?"

Lihuo Jackdaw snorted coldly, staring at Cui Yu with cold eyes.

The invisible pressure made Cui Yu break into a cold sweat.

"I was indeed reckless just now, please forgive me, senior."

"There must be no next time. Otherwise, I don't mind training a new disciple." Lihuo Jackdaw said coldly.

Seeing that Cui Yu still looked unwilling, Lihuo Jackdaw said again: "You are also an immortal cultivator in the early stage of foundation establishment. Can't you see that although this guy named Lin is not old, he is very difficult to deal with?"

"Senior, this..."

"You may not be able to detect it, but I can feel that the evil aura on his body is very strong. If this kid hadn't killed people like crazy, I really can't figure out why a twelve-year-old guy has such a strong evil aura."

"This... Lin really established his foundation at the age of twelve? If so, wouldn't he be a genius in cultivation?"

…

Driving the wind-controlling divine boat, Lin Fan did not dare to stop along the way.

After the spiritual power in his body was almost exhausted, he took out the Hui Yuan Dan to replenish his spiritual power without hesitation.

It took several days before Lin Fan returned to his cave.

boom!

The protective formation was fully activated, and Lin Fan sat down in the cave, breathing heavily.

Along the way, he was always on tenterhooks, fearing that Cui Yu would catch up and kill someone to seize the treasure. Lin Fan didn't feel relieved until he safely returned to the cave.

"This outing...was worth it!" Lin Fan said happily.

In the next moment, Lin Fan couldn't care less about his physical exhaustion.

With a wave of his hand, all the residual power was taken out.

Tens of thousands of small jade bottles are densely packed throughout the cave.

Lin Fan's eyes lit up.

After quickly taking out the mysterious copper bottle, he placed it in the spiritual spring, and then poured the collected residual power into it.

call!

An idea flashed on the mysterious copper bottle.

Soon, a small dragon about the size of a foot appeared again.

After his smart little eyes rolled around, his mouth opened quickly.

The spiritual energy of heaven and earth outside the cave was instantly absorbed by the mysterious copper bottle.

The residual power that was put into the mysterious copper bottle was rapidly strengthened at this moment.

The originally emerald green residual source power actually became transparent at this moment.

As time went by, it turned into as transparent as the spiritual liquid in the spiritual spring.

"Is this...the fully enhanced source power? It seems to be purer than the wood attribute source power I collected last time."

Lin Fan looked expectant.

Only after all the strange phenomena in the mysterious copper bottle disappeared did he pour out the enhanced original power.

After carefully comparing it with Cui Yu's tempering experience and introduction about the power of the perfect origin, Lin Fan was pleasantly surprised.

"It has completely reached the standard of perfect origin power. If the strengthened perfect origin power is used to improve the level of "Five Elements Chaos Sword Art", the foundation of the avenue will not be damaged, right?" Lin Fan said happily.

After happily putting away the strengthened perfect source power, Lin Fan put a bottle of unstrengthened defective source power into a mysterious copper bottle to continue strengthening it.

As the number of times of strengthening increases, the time interval for the mysterious copper bottle to strengthen its original power becomes longer and longer.

Lin Fan didn't intend to waste time.

Take out Cui Yu's experience of extracting the original power and study it carefully.

Cui Yu was a formation master himself, and his teachings were obscure and difficult to understand. Lin Fan had a hard time reading them at first.

However, Lin Fan couldn't help but read it patiently over and over again, pondering it carefully bit by bit.

After ten days, Lin Fan finally understood all of Cui Yu's thoughts.

"Cui Yu's realm is not high, but his understanding of the source of power is quite unique. His method of arranging formations to extract the source of power will definitely be of great use to me in the future."

"Especially the residual power that was given to me this time, it really helped me a lot."

Lin Fan was secretly happy.

Before the remaining residual source power could be strengthened, Lin Fan began to activate the "Five Elements Chaos Sword Art" to refine the perfect source power.

call!

The majestic power of the perfect origin was absorbed into Lin Fan's body and continuously refined through the "Five Elements Chaos Sword Art".

This process is extremely boring.

Lin Fan was not dissatisfied at all, and patiently meditated and refined.

Since the "Five Elements Chaos Sword Art" is upgraded from mid-level to high-level, it requires a lot of perfect source power. Lin Fan has never stopped since he started refining the power of perfect origin.

The time of cultivation always passes quickly.

In a blink of an eye, three months passed.

A thick layer of dust had fallen outside Lin Fan's cave.

But Lin Fan still stayed in the cave, showing no signs of coming out.

Soon, another two months passed.

A harsh rumbling sound came from Lin Fan's cave.

Immediately afterwards, the spiritual energy of heaven and earth within a radius of several hundred feet roared, pouring into Lin Fan's cave like a tide.

If anyone could see what was going on in Lin Fan's cave, they would be surprised.

Around Lin Fan, the rich spiritual energy of heaven and earth had gathered into small droplets.

Lin Fan, on the other hand, can refine spiritual energy extremely quickly. In the blink of an eye, the small droplets of spiritual energy within one foot of him were completely refined.

Just like that, as the spiritual energy in the cave became thinner and thinner, Lin Fan, who was still practicing, finally opened his eyes.

Lin Fan looked ecstatic as he felt the spiritual power flowing rapidly in his meridians when he activated the "Five Elements Chaos Sword Art".

"This cultivation speed is more than ten times faster than before. Has the "Five Elements Chaos Sword Technique" finally become a top-grade technique?"

Hard work pays off.

Lin Fan no longer has to worry about the slow speed of refining spiritual energy.

However, it didn't take long for Lin Fan to be happy.

A powerful aura suddenly shot towards Lin Fan's cave.

"Late stage of pill formation? Could it be that my strengthening of the "Five Elements Chaos Sword Art" was noticed by others?"
