"Don't worry, I have promoted so many disciples in the Cheng family, can I still make mistakes here?" Cheng Yu said with certainty.

"Okay, you guys can go in together!" Qing Yuanzi nodded and asked Xinhe and the others to go in too!

When everyone was ready, Cheng Yu told Qing Yuanzi how to activate the formation. Qing Yuanzi walked up to the formation and input spiritual energy into a small spiritual crystal outside the formation.

The formation suddenly lit up, and everyone was shrouded in the formation!

"This process may take a long time. The higher the level, the longer it takes to break through. I estimate it will take at least five days for them to complete the breakthrough!" Cheng Yu explained.

"In that case, let's wait here for five days!" Qing Yuanzi said.

After all, these are the future of Wuji Palace and cannot be lost, so it is better to stay and watch for safety!

——————————————————————

As time passed day by day, the conditions of these disciples seemed to be stable, and Qing Yuanzi gradually felt relieved.

"Xiaoyu, where are you going to practice this time?" Qing Yuanzi asked when he had nothing to do.

Cheng Yu is indeed a talented person in Wuji Palace. What's more, with his relationship with his daughter, Cheng Yu can also be regarded as his prospective son-in-law, so whether it is public or private, he does not want anything to happen to Cheng Yu.

"Actually, I have no direction. As you know, the Yin-Yang Mirror is not missing, but I have to find them!" Cheng Yu said helplessly.

"We old guys can't help you with this problem. We can only rely on your own opportunities!" Qing Yuanzi sighed and shook his head.

"The Yin-Yang Mirror you just mentioned refers to the Yin-Yang Mirror of the Sky Mirror?" But at this moment, Taoist Taixuan suddenly spoke.

"Uncle Master, do you know about the Heavenly Mirror?" Qing Xuzi said in surprise.

If Cheng Yu hadn't found the Five Elements Mirror, he wouldn't have known about the seven components of the Sky Mirror. But listening to what Uncle Master just said, he seemed to know about it.

"As far as I know, the Sky Opening Mirror is not a simple magic weapon. It has seven parts in total, which are composed of gold, wood, water, fire, earth and yin and yang. Seven fairy-level mirrors! Could it be the yin and yang mirror you just mentioned?

Is this the Yin-Yang Mirror?" Taixuan Taoist asked.

"Uncle Taishi! Have you ever seen the Open Heaven Mirror?" Cheng Yu suddenly became excited after hearing Taoist Taixuan's words.

There are probably not many people in this world who know that the Open Sky Mirror is a combined magic weapon, but he knows it, which means he must have seen it somewhere.

"I have never seen a real Open Sky Mirror, but I have seen a mural of the Open Sky Mirror in the ruins of the Forest of Death! It is clearly recorded that the Open Sky Mirror has seven components, and each part is independent.

Immortal weapon, the power is quite amazing.

Especially after the seven immortal weapons formed into the Sky Mirror, it has the ability to break through the void, and even an immortal can easily kill it!" Taoist Taixuan recalled.

"Death Forest? Uncle Master, shouldn't this Open Sky Mirror be at the Mirror Immortal ruins? How do you say you saw it in the Death Forest?" Qing Yuanzi asked doubtfully.

"That's right! It's the Forest of Death, not the ruins of the Immortal Mirror! In fact, the Forest of Death is not as simple as everyone thinks. If I guessed correctly, it should have been a very prosperous giant city.

But for some unknown reason, there seems to have been a devastating blow there." Taoist Taixuan seemed to recall his experience of wandering into the Forest of Death when he was young, and said slowly.

Qing Xuzi and Qing Yuanzi were very shocked when they heard this, but Cheng Yu became more and more strange the more he heard it.

He has entered the five major temples before, but Taoist Taixuan must have never entered the five major temples, because he must have the keys to the five major temples.

Since Taoist Taixuan has never entered the five major temples, how does he know these things? Are there other temples that he has not discovered?

But judging from his understanding of the Holy City, there are only five temples in the entire Holy City.

Also, why does this Heaven-Opening Mirror appear in the Holy City? Could it be that this Heaven-Opening Mirror was once a magic weapon of the Holy City?

"Why did this Open Sky Mirror leave traces in the Forest of Death?" Qing Yuanzi asked kindly.

"I don't know this anymore, but I'm sure that this Sky Mirror is closely related to the Death Sensen!" Taoist Taixuan said.

"Xiaoyu, you once obtained the treasure of the Death Forest. Have you discovered what the great uncle discovered?" Qing Xuzi asked, looking at Cheng Yu who had been deep in thought.

"No! I only know that there was indeed a very prosperous and very magnificent city there, but I have not found the Open Sky Mirror mentioned by Grandmaster Uncle just now. I am also very good. What exactly did Grandmaster Uncle mention?

Where did you find this?

Could it be that Grand Master's uncle discovered these secrets but failed to find the treasure of the Death Forest?" Cheng Yu asked.

"You actually got the treasure of the Forest of Death?" Taixuan Taoist did not answer Cheng Yu's words, but was shocked by what Qing Xuzi said.

This boy actually got the treasure of the Death Forest. Although he found these ruins when he was young, he did not get the treasure of the Death Forest. This is something he has always regretted.

But he didn't expect that a few years later, a junior from their Wuji Palace would actually get it. Maybe it was a kind of fate. Now he finally understood why this kid had such a low level of cultivation but had the ultimate soul weapon.

**It was obtained from there.

"Haha, accident! Accident!" Cheng Yu chuckled. He didn't want to mention too much about being in the Forest of Death.

Because many of the things involved here seem to have something to do with him, and he even seems to believe that he is really of the blood of the Holy City.

However, he couldn't let others know all this. As Taixuan Taoist said just now, there had been a devastating blow there.

Until he figures out why the Holy City was destroyed, he must not let anyone know that he is of Holy City blood.

"Whether it is an accident or not, it is your own opportunity after all!" Taixuan Taoist said.

"Uncle Taishi, why don't you tell me where you found the ruins of the Open Sky Mirror? Maybe I can go in and take a look this time, and maybe I can find the whereabouts of the Yin Yang Mirror?" Cheng Yu said with a smile.

.

"This is for you! Maybe it will really help you!" Taoist Taixuan suddenly threw a piece of silk cloth to him.

"Map? Is this a map of the Forest of Death?" Cheng Yu opened the silk cloth and saw that it was a map.

"That's right, this is the map I drew when I entered the Forest of Death. The red mark on it is where the ruins I found are. If you are interested, you can follow my map and go in and have a look!" Tai Xuandao
