"Master, why is it so difficult to break through to enlightenment resonance?"

Zao Wou-Ki asked curiously.

"Pioneering resonance, that is, the cave heaven opened up by your Yuan Hai, must be able to resonate with the power of the rules of heaven and earth. If you want your future cultivation to be able to break through to the extreme, you have to resonate with the power of the rules of heaven and earth, and this state is also called the unity of heaven and man! If your cultivation cannot resonate with the power of the rules of heaven and earth, then your future cultivation will stay above a certain realm, and then you will never be able to break through again! Generally speaking, there are many ways to break through from one great realm to another. But among the many methods, if you want to bring out the full potential of the previous realm, you need to resonate! Only when you have resonance can it mean that your potential has been completely stimulated!"

"I see!"

Zao Wou-Ki completely believed what Yi Zhen said, and he knew a lot of the theoretical knowledge that Yi Zhen said, even his father did not know.

"What you have to do now is to gather nine elixirs of different attributes! In this world, there are a total of five elements of law power and five special law powers: wind, electricity, darkness, and demons! When you introduce the power of nine different attributes inside those elixirs into the cave heaven in the Yuan Sea, it will be as if you sprinkled nine different colors of ink into it, and will absorb all the power of those nine different attributes!"

Yizhen continued.

"And will they repel each other in there?"

Zao Wou-Ki frowned slightly and asked.

"Don't worry, they won't, the cave sky will only be like a bottomless pit, devouring and fusing them all! You are only opening up a cave heaven now, and each different attribute power will have a limit! You find that no matter how much attribute power you infuse, that cave heaven still does not absorb that kind of energy into it, which means that that attribute power is enough! You need to change to other different attribute powers immediately!"

Yizhen explained.

"I see, I understand, so what elixirs should I go to next?"

"I'll send you a divine thought, and later, you will read that divine thought, and then you will know what elixir I want you to find. ”

"Okay!"

A quarter of an hour later, Zao Wou-Ki received a divine thought from Yi Zhen.

He immediately read the divine thought, and after a while, he realized what kind of elixir Yizhen wanted him to find.

In that divine thought, Yi Zhen did not ask him to find any specific elixir, but asked him to find those elixirs with nine different attribute powers.

"I see, gold-based elixir, I have to find an elixir that can grow in a place where metallic power is abundant! Let me check the books and see where this elixir is found!"

Zao Wou-Ki flipped through it for a night, and finally listed all the elixirs he needed on a piece of paper.

"Hopefully I'll be lucky enough to get all these elixirs together!"

The next morning, Zao Wou-Ki got up early in the morning, and he went to the local elixir shop first to see if there was any elixir he needed.

He searched for a long time and bought some elixirs.

Soon, he discovered that there were a lot of elixirs he needed to buy, and many of them were still very precious elixirs.

Yi Zhen needed him to gather an elixir containing nine different attributes, which made him feel very troubled.

Just as he was on the road, suddenly, he sensed a faint murderous aura behind him that locked on him.

Although it was only a faint murderous aura, Zao Wou-Ki still sensed it keenly.

"Someone is staring at me! That person deliberately restrained his life breath and strength!"

He looked back quietly, but he didn't notice anyone following him.

"Is it my delusion?"

At first, he thought it might be a delusion, but when he walked more than ten steps away, he concluded that he was really being targeted.

"It's not my delusion! The reason why I didn't find that person is because my strength is too weak! The person who followed me is not weak!"

After pondering for a while, Zao Wou-Ki knew what was going on.

In order not to attract the attention of the man behind him, he pretended to be careless and walked down the street.

At this moment, his mind was spinning rapidly, and he was thinking about how he should deal with the man who was following him behind him.

He had been walking for some distance when suddenly, he saw a child in front of him blocking his way.

The little friend held a letter in his right hand and said to him, "This brother, just now a sister asked me to hand over this letter to you! That sister said to me, this letter is very important to you, please open this letter and read it!"

Zao Wou-Ki's brows furrowed, and he used a peek to see if the kid in front of him was a cultivator.

After making sure that the child was not a cultivator, he carefully accepted the letter.

"Thank you, this little friend!"

Zao Wou-Ki said lightly.

When the child saw Zao Wou-Ki take the letter, he left immediately.

Zao Wou-Ki first smelled the letter, and after making sure that there was no problem, he opened the letter.

Then he saw the letter: "Zao Wou-ki, there is a killer who wants to kill you, go quickly! Go home! Don't go anywhere!"

The handwriting on the letter was crooked, and he judged that it was most likely written on purpose.

His brow furrowed slightly, he had already sensed that there was a killer behind him who had been watching him.

And now someone actually hinted at him to avoid the killer and not walk around, he couldn't figure out what was going on.

After reading the letter, with a wave of his right hand, a flame came out of the fingers of his right hand, burning the letter to ashes.

With a frown, he made contact with Yi Zhen inside the orb, and he asked Yi Zhen if he could sense a killer nearby.

Yi Zhen had told him that even though he was trapped in the orb now, his spiritual power was still far stronger than Zao Wou-ki.

Therefore, Zao Wou-Ki felt that Yi Zhen should be able to determine the exact location of the killer.

After a while, Yi Zhen told Zao Wou-ki: "Just a hundred meters away on the left, the person who is dressed plainly and has a pockmarked face, he is the killer you are looking for! That killer deliberately restrained any breath of life, I judge that person's cultivation is in the middle stage of fusion! You have to be careful!"

Zao Wou-Ki's consciousness was released, and soon, he saw what the killer who had been following him looked like.

From the point of view of appearance, the biggest feature of the killer is that there are a lot of pockmarks on his face, and at first glance, he is no different from passerby A and passerby B.

"That's a killer who is good at using daggers, you can use the Trail to step on the snow, and then combine it with the Auror Spear Technique to kill him at close range, but you must do it with all your might, he is a mid-fusion cultivator!" Yi Zhen suggested.

Zhao Wouji listened to Yi Zhen's words, and his brows furrowed slightly.

He took a deep breath, his eyes flickering.

Suddenly, Yizhen asked him to deal with a mid-fusion killer, and he felt that it would be very difficult for him to defeat the other party.

But now that Yi Zhen let him choose to go toe-to-toe with the killer, he chose to believe Yi Zhen's words.

"I believe the advice you gave me was the most appropriate!"

Zao Wou-Ki replied lightly.

"Of course, don't worry, I will help you, I will use the Divine Soul attack when you are closest to him, temporarily making his Divine Soul lose control of the physical body, but this process can only last for a short time. If that killer dodges my Divine Soul attack, then it's up to you to do the next! This battle is where your real battle begins!"

Yi Zhen said instigatingly.

Actual combat is completely different from a drill on the training ground.

When Zao Wou-Ki heard Yizhen's words, his blood boiled.

He took a deep breath and prepared for battle.

In the past, he was only practicing the Auror spear technique and some basic body skills, and he had never actually faced an enemy on the battlefield.

He knew that real combat must be much more dangerous than hard training alone, and if he was not careful, he would fall.

And now that he has such a great opportunity to practice, he feels that he should not let it go easily.

He looked around for a moment, and then walked towards the remote corner according to Yizhen's words.

At this time, the person who was tracking Zao Wou-Ki was none other than Zhang Mazi, the killer of the Feather Dynasty.

The reason why he was sent to deal with Zao Wou-Ki was because the people above judged that Zao Wou-Ki's current strength was only at the pinnacle, even if Zao Wou-Ki had dual martial arts cultivation, they would only be able to deal with Zao Wou-Ki by sending a killer whose realm was two or three small realms higher than Zao Wou-ki.

The Feather Dynasty would not casually send top masters to hunt down and kill Zao Wou-Ki, for the top masters of the Feathered Dynasty, in their eyes, Zao Wou-Ki was simply a small character, and they did not need to send top masters to deal with such a small character.

Therefore, they sent Zhang Mazi, who was in the middle of the fusion, to deal with Zao Wou-Ki.

"What is he going to do?"

Seeing that Zao Wou-Ki was walking towards a remote corner, Zhang Mazi was a little puzzled.

As soon as he thought about it, he felt that the current Zao Wou-Ki cultivation was just to open up the pinnacle, unless there was a master nearby who secretly protected him.

Otherwise, he felt that he could completely kill Zao Wou-Ki on the spot.

"Looks like my chance has come! If I miss, I'll run away right away!"

Zhang Mazi's eyes flashed, and when he looked at Zhao Wuji's pupils in front of him, a fleeting cold light quickly flashed.

He quickly followed, and at the same time, he had already reached for a dagger in his right hand.

It was a vicious dagger, and the dagger was so sharp that he had stabbed to death many of the people he wanted to assassinate.

He felt that next time, Zao Wou-Ki in front of him would be the same as the previous targets he assassinated, after the body was stabbed by the dagger, the poison quenched by the dagger would quickly enter the target's body, and the target would die in a very short time.

However, just when Zhang Mazi thought that he could succeed immediately, suddenly, he saw a white light flash in front of him.

The white light came suddenly, and he didn't react in time for a while.
