With Tang Huan's promise, Shanshan and the others also settled down.

When husband and wife reunite after a long absence, they will inevitably linger, like glue. However, as time went by, Shanshan, Feng Ming, Yu Feiyan and Mu Yan all felt an increasingly strong sense of urgency.

In the Great World of God Casting for decades, their strength has also been constantly improving.

Before the tribulation ascended to the sky, the strength of each of them was not inferior to Gu Jinglei, the city lord of the Heavenly Providence City of the Vermilion Bird Great World. However, although that kind of strength can be respected in the Nether Realm, but when it comes to the Heavenly Realm, it only makes their strength far stronger than ordinary celestials.

Compared with Tang Huan, who had already crossed the catastrophe and ascended to the sky decades ago, and even Jiu Ling and Xiao Budian, there was an incomparably huge gap.

They are not indulgent and comfortable, in this place, there are countless various cultivation resources such as pills and martial arts, and the immortal aura is extremely rich...... Tang Huan had created such a good cultivation environment, if they didn't want to make progress and cherish it, it would be a tyrannical thing.

Therefore, it didn't take long for them to follow Jiu Ling and Xiao Budian and start practicing diligently one by one.

Seeing that they insisted on this, Tang Huan only had to let them, although there would be no danger here, it would not be a bad thing to cultivate a little higher.

The original Huanglong Tianfu station, in the Tianlong Mansion in the inner mansion space.

Tang Huan sat cross-legged, his mind as calm as water.

Now, his cultivation has reached the limit of the Peak Heavenly King, and if he continues to absorb and refine the chaotic power in the source crystal, it will not be of much help to the improvement of his cultivation.

What he needs now is insight, opportunity.

It is difficult for their own cultivation to grow, and Shanshan and the others are desperately improving their cultivation, Tang Huan simply stopped cultivating, but returned to his own residence.

At the beginning, the fire phoenix had revealed that the reason why it left and went straight to this Jade Emperor City after it left and fully awakened was because it sensed the dragon veins here.

Now that he is free, Tang Huan happens to explore the situation of the dragon vein.

In his mind, the "Imperial Dragon Ancient Bell" was revealed in Tang Huan's palm, and after an instant, Tang Huan's huge mind was completely immersed in this ancient bell about the size of a sea bowl.

This ancient bell can manipulate the Great Array of the Imperial Dragon Heavenly Mansion, and it is closely connected to the Great Array.

Through this small ancient bell, Tang Huan was able to clearly sense every trace of the situation within the scope of this Sect Protector Array, even the slightest situation.

If you want to explore the dragon vein, you may be able to find some clues from this ancient clock.

This ancient bell also contains a Taoist map.

The ancient bell is a high-quality holy grade dao weapon, if under normal circumstances, it would take a lot of time for Tang Huan to figure out the dao diagram it contains, but now that this holy grade dao weapon has fused with his mental imprint, it is much easier to do this.

It didn't take long for the diagram of this ancient bell to appear unusually clearly in Tang Huan's mind.

Tang Huan was immersed in it, and deduced it little by little.

This diagram has countless unfinished meanings, and it is closely connected with the Great Array of Protectors of the Imperial Dragon Heavenly Mansion, and only by understanding this diagram thoroughly can we deduce the Great Array of Protectors of Heavenly Mansion. If there was really a dragon vein in this place, when Tang Huan had finished pondering the Great Array of Protectors, the dragon vein would have nothing to hide.

"Huh?

About a month later, Tang Huan seemed to be aware of it, his brows couldn't help frowning slightly, and he exhaled in surprise, and then closed his eyes and calmed down again.

"I see. ”

Almost a month passed, and Tang Huan's closed eyes suddenly opened, and a smile of realization appeared on his face.

Although this Protector Sect Array is extremely complicated, relying on the "Imperial Dragon Ancient Bell", Tang Huan has clearly understood all its conditions after some careful deduction. To Tang Huan's surprise, in the depths of this Sect Protector Array, there was actually another space hidden.

After Nie Cangsheng passed on the throne to Tang Huan, he told Tang Huan everything he knew about the Imperial Dragon Heavenly Mansion, but he did not have any information about that space.

Tang Huan believed that Nie Cangsheng should not have hidden it from him.

This meant that even the former mansion lord Nie Cangsheng didn't know about the existence of that hidden space. Not only Nie Cangsheng, but all the previous mansion masters of the Emperor Dragon Heavenly Mansion probably didn't know either. Even the Mansion Master was like this, not to mention the other Imperial Dragon Heavenly Mansion Monks.

Throughout the ages, in the entire Huanglong Heavenly Mansion, there may be only one exception, and that is the Founding Patriarch.

It's just that I don't know if Ji Qingtian tens of thousands of years ago is another exception?

However, after thinking about it, Tang Huan felt that Ji Qingtian should be like Nie Cangsheng and the others, and he didn't know anything about that hidden space.

Ji Qingtian is indeed extremely amazing, and he has fused dual-attribute Dao fire, and his sensing ability is amazing, just looking at his current status in the Nine Heavens "Xuanhuang Dao Sect", you can get a glimpse of his original situation. In the entire history of the Imperial Dragon Heavenly Mansion, it was extremely rare to be able to compare with it, but judging from what Tang Huan knew now, with his strength at that time, he should not be able to detect the existence of this hidden space.

Tang Huan is very confident in his strength.

In Tang Huan's feelings, Ji Qingtian before leaving Chimangtian back then, his strength should not be as good as he is now. But even he, after perceiving the abnormality of the Protector Array, he also worked hard to finally find the location of the hidden space, according to Tang Huan's judgment, this step alone took almost a month, and this was still under the condition that Tang Huan urged the Casting God Crystal and the "Nine Yang Divine Furnace" to the extreme.

No matter how powerful Ji Qingtian's sensing ability is, it is impossible to compare with such a Tang Huan.

It is very likely that he will not even be able to discover the slightest abnormalities in this Emperor Dragon Heavenly Mansion Protector Array, let alone find out the hidden space completely.

"The dragon vein, it should be in that hidden space. ”

Tang Huan stood up slowly, a smile flashed in his eyes, the dragon vein was so hidden, and he didn't know how the fire phoenix noticed it, he was able to discover its existence in the incomparably distant "Dan Sea Realm", and he also relied on his own feelings all the way to find the outside of the Jade Emperor City.

However, the fire phoenix incarnation has died, and its "phoenix essence blood" has long been taken by Tang Huan to give to Feng Ming, and now it is being refined and absorbed by Feng Ming, and how it found the dragon vein is no longer very important. The important thing is that Tang Huan has roughly found the location of that dragon vein.

Since this is the case, Tang Huan naturally won't let the dragon vein stay under his nose all the time.
