"How did the Martial Emperor's Wisdom Tooth end up in the hands of the Black Sky Sect?" Zhou Dao was puzzled.
```
```
The Black Sky Sect loudly claims to be offering treasures to the capital, yet actually, the Martial Emperor's Wisdom Tooth is inherently an imperial relic. How could it have fallen into their hands?
```
```
"That year, the Martial Emperor dispatched a hundred thousand troops to besiege the Longevity Sect. Unable to overcome them for a long time, he thus went to the Black Sky Sect and exchanged his Wisdom Tooth for a supreme treasure."
```
```
"A treasure that besieged the Longevity Sect!?" Zhou Dao's heart stirred slightly.
```
```
When he was cultivating his External Avatar, he had seen a corner of the past and knew that the Taoist Sect's nine gates were of the same origin.
```
```
Back then, a supreme existence entered the Western Great Swamp, created nine External Avatars, scattered them across the world, and established the nine sects.
