In the middle of this building, there is an ancient tower-shaped building, the building has ten floors, and each floor stores the spiritual vein map.

Among them, the highest level of the spirit vein map is the most valuable phoenix vein map of Tiangang Gate.

Then they were ranked down in turn, and the spiritual vein diagram, which was slightly worse, was ranked on the ninth layer.

The spirit vein diagram that is one more missing is placed on the eighth layer.

In short, from the first layer, the higher you go, the higher the grade of the spirit vein diagram, the more precious it becomes.

However, today, He Huimin did not bring Zhang Zichen and Zhang Jianfeng to the tenth floor, the three of them stopped when they came to the ninth floor of the tower.

The spiritual veins of the ninth layer are some medium-grade dragon veins and phoenix veins, which belong to the second precious spiritual vein map storage place of Tiangangmen.

"Min, what are we doing here?" Zhang Zichen couldn't help but ask when he learned that this tower was the top secret spiritual vein storage place of Tiangang Gate.

"I don't know, but I guess it's something about my second senior brother, and Master asked me to take you into that mid-grade dragon vein. And the corpse and soul of my second senior brother were placed there to nourish. He Huimin pointed to one of the spiritual veins and explained.

"Second Senior Brother?" Zhang Zichen understood, "Your second senior brother is actually Yuan Yingxing, the son of Senior Yuan. ”

As for Yuan Yingxing, Zhang Zichen had heard earlier that he was Yuan Xuanqi's only son and was killed by Ling Zihan.

Fortunately, although Yuan Yingxing was killed, his body was intact, and the three souls and seven spirits had not gone far, and they were all taken back by Yuan Xuanqi.

Although Yuan Xuanqi is a cultivator and understands this reincarnation, he still doesn't want to see his son die.

So, Yuan Xuanqi preserved his son's body and soul, and over the years, Yuan Xuanqi searched for treasures everywhere, mainly to pull his son back from the ghost gate.

Yuan Xuanqi gave up his cultivation and everything he had for his son, he just wanted his son to be resurrected.

"Min, I heard you just now, the highest-grade spiritual vein in your Tiangang Sect is the Phoenix Divine Vein, which is stored on the highest floor, the tenth floor of this tower. But now you, your second senior brother's corpse and soul are kept in a medium-grade dragon vein here, why didn't Senior Yuan store his son's corpse and soul in the Phoenix Divine Vein?"

In Zhang Zichen's opinion, since Yuan Xuanqi was the head of Tiangangmen, he could completely store his son's body in the Phoenix Divine Vein.

He Huimin explained: "This phoenix divine vein, for a long time, is one of the few ancestors of our Tiangang Sect to live there for a long time to cultivate, and very few people disturb it. Even my master rarely bothered them. And the dragon veins and phoenix veins of the ninth layer, although the grade is slightly inferior, they are all top-grade spiritual veins, and ordinary people cannot enter here to cultivate. Moreover, to raise the corpse and soul of my second senior brother, the master has already vacated a medium-grade spiritual vein for him, which is already a very good treatment. ”

Zhang Zichen said, "I see." ”

He Huimin snorted, "Okay, you two go in with me first, Master has been waiting inside for a long time." ”

"Then you lead the way. Zhang Zichen replied.

He Huimin turned his head at this time, looked at a dragon vein diagram hanging on the wall, and directly used light power to fly towards the dragon vein diagram.

I saw He Huimin directly crashing into the dragon vein diagram, and the dragon vein diagram burst out with a burst of white light, and He Huimin's figure had been lost in the tower.

He Huimin took the lead, Zhang Zichen and Senior Brother Zhang Jianfeng glanced at each other, "Senior Brother, let's go in too!"

After that, Zhang Zichen took the lead in flying up and flew towards the dragon vein diagram.

After two white lights in a row, Zhang Zichen and Zhang Jianfeng entered this medium-grade dragon vein diagram at the same time.

When the scene appeared in front of Zhang Zichen's eyes again, he had already entered this dragon vein diagram.

Unlike other dragon vein diagrams, Zhang Zichen entered here and appeared in a huge closed room.

The temperature here is even much colder than the outside.

Zhang Zichen couldn't help but tighten his coat, but even so, he could feel a trace of cold air penetrating into his skin from the air.

Next, Zhang Zichen looked up and saw a scene that shocked him.

Dozens of meters away from Zhang Zichen as the center, it is all a confined space, and in this space, the reason why it is cold is because here is completely a huge ice cave.

In this entire confined space, there is a thick layer of ice everywhere.

The air exhaled by Zhang Zichen and Zhang Jianfeng immediately turned into a drop of ice and fell to the ground.

Zhang Zichen can be sure that the temperature here is definitely minus 50 degrees, and ordinary people will really be unbearable when they enter here.

In addition to the scene here, Zhang Zichen also saw that in addition to He Huimin and Zhang Jianfeng, there were several people standing there not far away.

There were three people, one of them was Yuan Xuanqi, and the other two were Liuyue Shuang and Qi Jingyun.

Today, all the backbone elites of Tiangangmen have arrived, and Yuan Xuanqi must have something to order.

Yuan Xuanqi saw Zhang Zichen and the three of them coming in, so he waited in the distance.

"Let's go, Master is waiting for us. He Huimin said a word, and then pulled Zhang Zichen forward.

"Min, why is this a confined space? And it's freezing everywhere, and the temperature is so low. Zhang Zichen couldn't help but ask.

In Zhang Zichen's impression, the so-called dragon vein should be the same as the heaven and earth dragon vein of the Dragon and Tiger Taoist Temple, with mountains and water, trees and grass.

Moreover, in the dragon vein diagram, the temperature is suitable and the aura is strong, which is suitable for cultivators to cultivate.

But here, in addition to the strong aura, there are no mountains and no water, and the surroundings are closed, and it has become a huge ice cave.

This made Zhang Zichen a little depressed.

However, He Huimin's explanation made Zhang Zichen understand this qiē.

He Huimin explained: "Are you stupid? It's been a long time coming, this dragon vein is the place where my master used to store the corpse and soul of my second senior brother. Therefore, in the early years, my master used a thousand-year-old ice spirit bead to town here, and with this thousand-year-old ice spirit bead, coupled with the aura in this dragon vein, this can ensure that my second senior brother's body will not decay. ”

Zhang Zichen suddenly realized, he smiled embarrassedly: "I always thought that the dragon vein diagram was full of mountains and rivers, but I forgot about your second senior brother, his corpse is indeed easy to decay at ordinary temperatures." ”

"Hmm!" He Huimin nodded, "That's why my master will use these treasures to suppress the corpse of my second senior brother." ”

"Over the years, Senior Yuan must have also paid a lot for his son, which is really hard. Zhang Zichen was sad, followed He Huimin, and walked in the direction of Yuan Xuanqi.
