In the next half year, Chu Yunfeng devoted himself to cultivating the Phantom Heavenly Technique and the Nine Immortal Killing Styles taught by Meng Wenxian.

The Phantom Heavenly Technique is an extremely unusual method of concealment, much more magical than the tenth form of the Heavenly Sword Technique: Void. With Chu Yunfeng's current cultivation strength, in the case of using the Phantom Heavenly Technique, it would be difficult for even a powerhouse in the Mahayana realm to find his traces.

This was a means specially prepared by Meng Wenxian for Chu Yunfeng to deal with the Dark Demon Shadow Death.

Under Meng Wenxian's teaching, Chu Yunfeng's understanding of the Nine Styles of Killing Immortals quickly entered the doorway, allowing his strength to improve by leaps and bounds, saving him nearly a hundred years or even more time for contemplation.

Compared to before, although he could only use the first form of the Nine Immortal Killing Forms, the combat power that burst out with all his strength was infinitely close to the middle stage of the Mahayana realm. It is no exaggeration to say that he can now fight against any powerhouse in the early stage of the Mahayana realm.

After fusing the Sword Ji and the Cleansing Spirit, the Sword Spirit of the Killing Immortal became a child, and the whole person was like a blank piece of paper, except for one rule: Killing Immortals, Killing Demons, Killing Demons, and not killing people.

If Chu Yunfeng wanted to exert his power beyond the early stage of the Mahayana realm, he had to seek the cooperation of the Immortal Sword Spirit. In the current period, it is good for him to deal with the dark demons, once he leaves the Sword Spirit Hall and returns to the Sky Eagle Continent, he will have to deal with people more, and I am afraid that he will need to find a way to solve it.

"Senior, the Sword Spirit Hall is only a temporary appearance, and the junior is not yet expected to be promoted to Mahayana, if the physical body is in hand in the future, how can I contact the senior?" asked Chu Yunfeng when parting.

Meng Wenxian took out a jade plate, handed it to Chu Yunfeng, and said, "This is my sword master token, after finding the flesh, you only need to capture a trace of breath and put it on the token, and it will take you to find me!"

"The Shadow Death Technique is extraordinary, you don't want to fight, just escape from the Sword Spirit Hall as much as possible! Remember! Remember!" Meng Wenxian was worried that Chu Yunfeng would be young and vigorous, and he would rely on the methods he had just learned to fight with the Shadow Death, so he reminded.

"Remember, juniors!

Chu Yunfeng arched his hand, turned into several figures, and fled upward.

After a few breaths, as soon as Chu Yunfeng entered the Sword Spirit Hall, Shadow Death sensed the abnormality and threw out a blow fiercely. When the attack landed, strings of shadows rushed in all directions, making it impossible for Shadow Shadow to tell which was his real body.

But Shadow Death is not an ordinary powerhouse, and immediately used a wide range of killing moves, enveloping all the shadow bodies, and quickly shattering them, but there was no human shadow.

After a while, the Sword Spirit Hall returned to normal, and there was no other trace to be found. But he knew that someone must be hiding here.

Secretly, Chu Yunfeng was also afraid for a while. Shadow's reaction was so fast that it almost forced him out. He clearly felt that even though his strength had improved a lot, he must not be the opponent of Shadow.

The pinnacle of the Mahayana realm is really extraordinary!

In this way, Chu Yunfeng not only followed Meng Wenxian's warning, but was more cautious, making up his mind not to make a move with the shadow as much as possible, but to flee directly from the Sword Spirit Palace.

Shadow Death naturally knew Chu Yunfeng's purpose, but fortunately, the Sword Spirit Hall was not closed, and there were exits in all directions. After all considerations, Shadow Death returned to the place where he had originally smashed the teleportation array, and searched for it in the direction of the teleportation array, and finally found a clue, and shot it decisively with one palm.

Bang!

After a palace wall collapsed, no trace was found, and Shadow immediately changed direction and continued to look in another direction.

And at this moment, Chu Yunfeng was hiding behind a broken palace wall, if Shadow Death used a little more strength just now, he would be able to force it out.

"It's worthy of an old monster tens of thousands of years ago, and his mind is too meticulous! I can actually judge the direction I am moving from the traces of the teleportation array!"

This time, if he wasn't lucky, I'm afraid he would have to go down to accompany Shu Shilan and Wu Buju.

Shadow Death had just attacked in this direction and would not come back for the time being, so Chu Yunfeng continued to flee in the direction pointed by the teleportation array. After a few hours, he finally came to the edge of the Sword Spirit Hall, and as soon as he broke through the barrier in front of him, he was captured by the Shadow Death.

Syllable!

Chu Yunfeng couldn't react in time, he was hit on the spot, flew out for several zhang, and sprinkled a piece of blood in midair. The only fortunate thing was that the shadow was far away from here, and the lethality caused was not high, and Chu Yunfeng was not fatally injured.

He didn't dare to stay, so he immediately got up and ran.

After walking out of the Sword Spirit Palace, it is not within the control of Shadow Death, and it is much safer than before. But he didn't dare to be careless at all, after all, the other party was a dark demon at the peak of the Mahayana realm.

An hour later, on the way, I met many monks who were desperately struggling in the squeeze of the pillar of light, only to learn that they had not escaped from the Yao Palace, but had entered the Baicao Palace.

"Roar!"

An inhuman beast roar suddenly sounded, but it was the shadow that turned into the body of a dark demon and chased after it. But all the monks who got in the way died miserably under his collision.

The shadow in the dark demon state seemed to have become very sensitive to smell, no matter how Chu Yunfeng changed his direction and hid his aura, he could never get rid of it. If it weren't for the extraordinary magic of the Phantom Heavenly Technique, he would have fallen into the mouth of the tiger and been killed by the Dark Demon.

"It's not a way to go on like this, you have to get out as soon as possible!" Chu Yunfeng was anxious, the longer the time dragged on, the more dangerous it would be for him.

After escaping for a while, he stopped near a disc. Standing next to him, he could clearly feel the unusualness of the disc, and just wanted to put it aside, the disc opened automatically, and a breath from hell suddenly came to the surface.

If he had stayed in the past, he would have run away a long time ago, but now that the shadow is chasing after him, encountering such a dangerous place, it makes him happy in his heart. For the sake of safety, he didn't rush into the disc right away, and was about to investigate, when he felt the shadow chase after him.

"It's a blessing or a curse, it's a curse that can't be avoided! Fight!" Chu Yunfeng gritted his teeth and decisively rushed into the disc.

As soon as he entered the disc, he saw a group of monsters with dog bodies and ghost faces staring at him with green eyes, and Chu Yunfeng couldn't help but start his scalp tingle. That breath of hell is what they emanate.

"Lingmang!" Chu Yunfeng saw Xun Qixi buried in Lingmang's mouth with his own eyes, so he recognized the origin of this monster at a glance.

His current strength is much stronger than that of Xun Qixi back then, but the aura fluctuations on these Lingmang's bodies are not something that ordinary monks can deal with.

"Phantom Heavenly Technique!" Chu Yunfeng decisively hid his tracks, and in the next second, the restless spirits began to attack, and cracks appeared in the void.

If he hadn't been able to hide, he would have really died.

Rumble!

Just then, there was a crash, and Shadow Death rushed into the disc.

Losing Chu Yunfeng's traces, the Lingmangs were already furious, and when they saw someone coming again, they immediately spewed out a large amount of corrosive liquid in unison, shooting towards the shadows.
