"You really didn't disappoint me. You're a clever child too. What I'm thinking is exactly what you're thinking, so the two of us can be considered kindred spirits. There are many things that don't need to be spoken aloud for you to understand perfectly."
"I'm quite pleased to see you like this. It saves me the trouble of wasting my breath. Since that's the case, do as I said. I'll start helping you remove this seal now."
If they truly wanted to remove the seal, the location and timing were extremely important. They needed to perform it within the Great Tang, but they could not let others know about it or alert anyone.
They still needed to find a place with few people. They planned to wait until evening, when the moon appeared and absorbed the Essence of Sun and Moon. Only then would removing the seal achieve the best results.
However, this would consume a great deal of energy. To guard against unexpected incidents, they needed to find a medicinal herb. This herb had miraculous effects and could restore the spiritual power within one's body very quickly.
This medicinal herb was a treasure of the Heavenly Realm. Uchiha Hiko wanted to go to the Heavenly Realm and obtain it for his own use. Though it was somewhat improper, Uchiha Hiko did not think it was beyond his capabilities.
This Nether Vine also absorbed the Essence of Sun and Moon in the heavens, so the two similar things would greatly enhance each other's effects. However, obtaining this treasure would not be easy.
If Uchiha Hiko truly wanted to obtain this herb, he certainly could not do so openly. He had long been at odds with the Heavenly Realm, so how could he lower himself and ask for such a treasure?
