After Wu Qingdao left, Cheng Yi spent some time continuing to study the Cool Talisman, and finally finalized the Cool Talisman before he was about to fall asleep.

The cool talisman is a talisman he has been developing recently, which is specially made for the people who are watching the live course in the square.

It stands to reason that as a high-level talisman master, the creation of a junior talisman is as simple as drinking water for him, but there is a premise for this, that is, this talisman can only be used for other purposes.

No matter how well the talisman is portrayed and used, he is invincible in this world, so when creating a primary talisman, he doesn't have to care about the number, type, arrangement, and complexity of the spiritual power routing of the runes and rune patterns of the new runes he is creating.

Because his rune level is too high, these things are not the difference between lifting a bucket of water and carrying two buckets of water, but the difference between holding a grain of sand and holding two grains of sand.

However, for other people who have a very low level of runes or even do not have the ability to depict runes, a random creation of an unoptimized rune may be more difficult to learn and make than an intermediate rune.

Because of this kind of primary talisman created by him as a senior talisman master, he often needs to use the talisman making skills of intermediate or even advanced talismans.

That's why the new talisman he created casually is likely to be used only by him.

However, optimizing a primary talisman is not that simple, he not only needs to optimize the rune, optimize the pattern, optimize the materials and spiritual power routing, he also needs to consider the suitable people of the talisman, the adverse reactions after using the talisman, and so on.

Cheng Yi wanted to solve this problem during the first live broadcast, and after upgrading the rune to an advanced level, Cheng Yi immediately began the research and development of the cool rune.

After a few days of research, today, it is finally possible to finalize the sample.

Maybe the current cool charm is not perfect, and it has to go through the personal production and use of the masses, and then give corresponding feedback before the final sample.

But at least, Cheng Yi can basically guarantee that it will not be difficult for the vast majority of people to depict this talisman.

After finishing a major matter, the night was late, and Cheng Yi was sleepy, so he finally washed his face, dried it with a towel, and went to bed.

However, in the dark night, there was always a pair of clear eyes, staring at the window of Cheng Yi's bedroom, listening carefully to the movement in the house, until he heard Cheng Yi go to bed and fall asleep, and his breathing gradually became slow and steady.

After waiting for another quarter of an hour to confirm that Cheng Yi had completely fallen asleep, the black-clothed man began to approach Cheng Yi's room.

It's not that the man in black is careful, but Cheng Yi's prestige is too scary.

First, a master in the middle of the Martial Sect Realm sneaked up on Cheng Yi at night, and his entire army was wiped out, and the man in black was also seriously injured and fled in embarrassment, and then disappeared.

After the black-clothed man checked the yin, the master of the middle stage of the Martial Sect Realm was the head of the Huifeng faction, Liu Heifeng, it is said that Liu Heifeng has not appeared again during this time, and it is estimated that he is still recuperating from his injuries.

Then, there was another Cheng Yi battle against the mid-stage swordsmanship master of the Wuzun Realm, defeated that master, and fled in embarrassment.

These two major achievements made the man in black have to be careful.

The first battle record, said that Yin Cheng Yi's vigilance is extremely high, even if he is asleep, he has always kept a heart, and his perception is keen, at least in the middle of the Martial Sect Realm, he will not be able to sneak up on him.

The second battle record, after Cheng Yi used the talisman, he at least had the strength of the middle stage of the Wuzun realm.

The man in black's own strength is in the late stage of the Wuzun Realm, but he doesn't dare to guarantee whether he can win Cheng Yi in a head-to-head battle, after all, as a child now, Cheng Yi has not experienced a battle that has been forced out of his hole cards.

Moreover, who knows if Cheng Yi still has a talisman in the Martial Spirit Realm!

If Cheng Yi really has a talisman of the martial spirit realm, if he is still discovered by him, wouldn't it be very dangerous, and he won't be able to run away when the time comes.

However, the man in black only hesitated for a moment, and then continued to approach Cheng Yi's bedroom.

If he is really discovered, and he can't resist it, he will take off the mask and reveal his identity, I believe that Cheng Yi will not hurt himself after knowing his identity.

In this way, the man in black was very careful, walked a few steps and stopped for a few breaths, and then walked a few steps, and finally reached the corner of the wall under Cheng Yi's bedroom.

Cheng Yi's bedroom is on the second floor, and the man in black needs to jump up.

This was very simple for the man in black, and with a slight jump, the man in black climbed to the edge of the window of Cheng Yi's bedroom.

The man in black did not rush to open the window, but slowly adjusted his breathing, then took out a thin letter from his clothes and carefully slipped it through the crack in the window.

When the letter was completely stuffed in, the man in black exhaled slowly.

Fortunately, Cheng Yi didn't wake up.

The man in black was about to leave, but then he paused again.

I have done this, if it was me, I would have woken up a long time ago, but Cheng Yi didn't wake up like this, could it be that he thought too much, in fact, Cheng Yi was not as godly as he thought?

"There aren't many opportunities to observe him secretly, why don't you open the window and take a look before leaving?"

The man in black hesitated, and after a while, he decided to open the window to take a look.

So, the man in black stretched out his hand and gently pushed the window in front of him, the window was getting bigger and bigger, and Cheng Yi's sleeping figure was already looming.

"Isn't it as godly as I thought?"

Just when the man in black was proud, he suddenly saw a talisman posted on the inside of the window, and he didn't see the window closed just now, but he finally found it at this time.

Moreover, the talisman is now glowing, and the Yin Manifestation has been activated!

"Who!"

Cheng Yi sat up from the bed abruptly and burst into applause!

The man in black didn't care much, and immediately exerted his maximum speed and fled like a fly.

Cheng Yi used the Wuzun Realm family bucket and slammed it towards the window, the black shadow was already gone.

Looking at the black shadow that was already too far away to be seen, Cheng Yi was afraid for a while.

Just looking at the speed of the man in black, it must be above the middle stage of the Wuzun Realm, and it is very likely to be the late stage of the Wuzun Realm, if he suddenly attacks himself, it is really dangerous, if he doesn't handle it well, he may lose his life!

But then after looking at the warning charm on the window, Cheng Yi was a little puzzled.

"No, this warning charm is not triggered by hostility, but by being physically activated by the window being opened."

This is yin, and the person who comes does not have any hostility towards himself.

But since there is no hostility, what is the other party here for, to come and see himself sleeping? Impossible, right?

"Huh? This is......? ”

Cheng Yi noticed the letter that had fallen by the window.

When I picked it up, it read: Cheng Yi personally opened.

After opening the envelope and reading the contents of the letter, Cheng Yi's expression was a little surprised.

"What is Lingyun Sect? Am I being targeted by it? But who is so kind? Came quietly in the middle of the night to remind me, and did not reveal my identity. ”
