The area of the inner city is not large, about one-tenth of the entire Dandi Immortal City.

However, the entire inner city is the territory of the Alchemist Alliance, which is closest to Tianyao Mountain and the most core area of Dandi Immortal City.

The layout of the inner city is from south to north, and it is divided into three parts: "Ten Thousand Medicine Immortal Pavilion", "Danmeng Hall" and "Dandao Emperor Tower".

After Yang Yi entered the inner city from the south gate, passed through the "Ten Thousand Medicine Immortal Pavilion", and entered the "Danmeng Guild Hall", he finally saw his master Wu Qi Ancestor.

Although Wu Qi Ancestor is a member here, there is only one room in the "Dan League Hall".

As for Yang Yi, although he has the qualifications to enter the inner city, he is not yet qualified to enter the "Danmeng Hall".

"You look good, it seems that you should have a good harvest in the forbidden land of Tianyao Mountain this time. What about the three companions you invited?"

In Wu Qi Ancestor's room, he looked Yang Yi up and down for a moment, and nodded with a satisfied smile.

"Back to the master, they are all visiting the outer city. The disciple was afraid that the master would be worried, so after entering the city, he came to see the master as soon as possible. ”

Yang Yi replied respectfully.

Yang Yi remained silent, secretly observing the movements of Wu Qi Ancestor.

This time when he entered the forbidden land of Tianyao Mountain, Yang Yi thought of a question several times after learning that his identity had been exposed.

In the outside world, there are currently two people who know that he is related to Emperor Yan.

One is the Lingxi Fairy, and the other is the Wu Qi Ancestor.

Although they didn't know much and didn't know much about it, Yang Yi didn't dare to take it lightly.

How powerful his enemy is, Yang Yi knows very well.

In the Nine Heavens Star Domain, the identity of his clone is the Great Heavenly Venerable, and he can mobilize many Celestial Clans for his use.

Under the Nine Shadows Demon Abyss, his clone is the Nine Shadows Demon Venerable, and he commands countless demon clans and ghost clans.

Under such a behemoth, whether it is the Lingxi Fairy or the Wu Qi Ancestor, they are all just ants.

"Apprentice, the teacher noticed that there seems to be a very special witch aura on your body, could it be that this time you found the inheritance of the witch clan in the forbidden land?"

After pondering for a moment, Wu Qi Ancestor asked with a slight hesitation.

"Don't get me wrong, I'm just a little curious. ”

Wu Qi Ancestor seemed to be worried that Yang Yi would have a misunderstanding, so he hurriedly added an explanation.

Yang Yi said: "That's right, the disciple recaptured the bronze witch face from a Heavenly Clan. ”

As he spoke, Yang Yi's mind moved, and the bronze witch face instantly appeared on his face.

Seeing this bronze witch face, Wu Qi Ancestor suddenly took it up excitedly, and his body couldn't help but tremble a little, staring at the bronze witch face carefully.

This bronze witch mask has been refined by Yang Yi, and the inheritance has been obtained by him, so he doesn't worry about anything else.

He took it off directly and handed it to Wu Qi Ancestor.

Wu Qi Ancestor shook his hand and took the bronze witch face, and held it in his hand to observe it carefully.

After a long time, he finally calmed down, looked at Yang Yi's gaze, and became more and more full of appreciation!

"Yes, yes! I didn't think you would be able to retrieve this treasure! I hope that in the near future, within these nine heavens and ten earths, a heavenly wizard will be born again!

Wu Qi Ancestor was still a little excited, and he returned the bronze witch mask to Yang Yi.

As for the fact that it had been refined by Yang Yi, Wu Qi Ancestor didn't ask, and Yang Yi didn't mention it much.

"By the way, with your Dan Dao attainments, if you want to come to that Witch Dao Medicine Ding, you should have already condensed it, right?"

Wu Qi Ancestor seemed to have thought of something and said to Yang Yi.

"Yes. Yang Yi nodded.

Wu Qi Ancestor smiled: "Very good. In this case, then this time the Dandao Emperor Pagoda is opened, you must go and break through. If you can break through this tower, you will have a chance to enter the Heavenly Medicine Mountain. This has immeasurable benefits for you to improve the medicine tripod!"

As he spoke, Wu Qi Ancestor flipped his palm and took out a jade slip and handed it to Yang Yi.

"This is some information about the Dandao Emperor Pagoda and Tianyao Mountain, you can take a good look. ”

Yang Yi took the jade slip in his heart, and then released his divine thoughts, leaned into the jade slip, and examined it carefully.

The content of the jade slip is divided into two parts, one part introduces the matter of the "Dandao Emperor Tower", and the other part introduces some of the situation of Tianyao Mountain.

Yu Jian's introduction to the "Dandao Emperor Tower" is very detailed, but about Tianyao Mountain, the introduction is relatively brief.

"Dandao Emperor Tower" is a landmark building in Dandi Immortal City.

Of course, it's not as simple as a building in the usual sense.

In fact, it is a Heavenly Forbidden Pagoda that contains the mysteries of the Dan Dao and even the laws of the Dan Dao.

This pagoda was built by an ancient Dan Sanctuary to cultivate and ascend to the Dan Dao realm.

The "Dandao Emperor Pagoda" is opened every three years, and the time of each opening is three months.

Any Dan King of the Alchemist Alliance has a chance to break into the tower, and whether there can be a second chance depends on the specific performance in the "Dan Dao Emperor Tower".

Two years ago, when the Ancient Forbidden Land of Tianyao Mountain was opened, it also coincided with the opening of the "Dandao Emperor Tower".

When Yang Yi and the others entered the forbidden land to explore, Wu Qi Ancestor, accompanied by King Sun Yaoquan Dan, broke through the "Dandao Emperor Tower" together.

The "Dandao Emperor Tower" has a total of nine layers, the first five layers correspond to the five realms of the Dan King, and the last four layers correspond to the four realms of the Dan Emperor.

Wu Qi Old Ancestor and Sun Yaoquan both broke through the first five layers and stopped at the sixth layer.

According to the meaning of Wu Qi Ancestor, since Yang Yi has condensed the medicine tripod, if he goes to break into the "Dandao Emperor Tower", he will definitely gain a lot.

Breaking through the first four layers of the "Dandao Emperor Tower" can condense the mystery of the medicine tripod to perfection, and if you can break through the fifth layer, you can make the mystery of the medicine tripod advanced to the law, so as to make it turn into a law artifact.

With the assistance of this medicine tripod law artifact, it will have an immeasurable effect on refining the pill in the future.

It is no exaggeration to say that once Yang Yizheng can quench the medicine tripod into a Dan Dao Law artifact, no matter what kind of pill he refines in the future, he will be able to increase the pill rate and quality by several percent out of thin air.

As for the specific value of the promotion, it is naturally related to the level of the law it masters, and the higher the level, the more it will be improved.

Yang Yi naturally knows this point.

He also knew that with the assistance of Shennong Ding, coupled with his previous alchemy talent and experience, when he was refining pills below the level of Shendan, he was able to make the Dan rate reach 100%, and the quality of the pills was also very high.

After all, Xuanyuan Yan was Emperor Dan before, and with Emperor Dan's experience, these are naturally not a problem.

And once he refines the Divine Pill, his success rate will not reach 100%.

Even Xuanyuan Yan in his previous life, when refining the Divine Pill, when the Cheng Dan rate was the highest, it was only sixty percent.

The refining of the Divine Pill has already involved the laws of the Dan Dao, and the slightest carelessness may lead to the collapse of the Divine Pill.

Since this "Dandao Emperor Tower" is so magical, Yang Yi naturally wants to go in and break in.

And according to the description in this jade slip, Yang Yi naturally guessed its origin.

Needless to say, this "Dandao Emperor Tower" must be from the handwriting of the "Heavenly Medicine Dan Sage".

The "Heavenly Medicine Pill Saint" is the original owner of this Heavenly Medicine Pill Realm.
