Emperor-Grade Heavenly Wisdom Fruit

Under the decision of Ming Yao, War-Heaven Dragon, Fu Dao, and the others, they decided to tunnel through the depths underground toward the secret realm entrance.

Though this was a massive undertaking, the surface was scorching and difficult to traverse. Only by traveling underground could they bring everyone to the secret realm.

Lin Yi knew nothing of what was happening outside.

On the third day after entering the secret realm, he had already subdued the Great Banyan Tree and the red-black Emperor Dragon, Liliya, and signed a certain Blood Oath Contract with them.

This contract originated from the Dragon God Legacy and could affect Emperor Realm experts.

After signing the oath, the Great Banyan Tree's attitude toward Lin Yi changed. Aside from certain major secrets, it told him much information about the Demon Dragon Realm.

For instance, this secret realm known as the Dragon Realm had been created by the Dragon God in the past, specifically to nurture the descendants of the Magic Dragon Clan.

As long as one lived in the secret realm for a long time, their Demon Dragon bloodline would gradually become denser and purer. Even ordinary living beings could be tainted by the aura of Magic Dragons and become part of the Sub-Dragon race.

Of course, aside from the Banyan Dragon itself, two powerful Emperor Dragons also lived in the Dragon Realm. They were likewise the Dragon God's closest descendants.

One of them was the Star Dragon. It had originally been a Holy Dragon, but after breaking through the shackles of its bloodline and entering the Emperor Realm, it could be called a Star Demon Dragon.

Over a hundred thousand years ago, the Star Dragon had entered the Emperor Realm and become the second strongest being in the Demon Dragon Realm beneath the Dragon God.
