The Octopus King's demonic nucleus was the size of a fist, slightly larger than an average-sized demonic nucleus.
Qingfeng Li placed the demonic nucleus in his hand and channeled vital essence into it. It formed a black protective light veil around his body, blocking all the water from touching him.
Qingfeng Li found that the octopus's demonic nucleus acted similarly to the water repellent pearls, except that the ability to avoid water and the area of water avoidance was not as great as a water repellent pearl.
Qingfeng Li was very happy with this demonic nucleus. Now, he would be able to move freely in the sea and would not be interrupted by water pressure as much.
Qingfeng Li placed the demonic nucleus into his left black ring. This black ring was an interdimensional ring which had a hundred square meters of storage space, which he had retrieved from the Spirit King's Tomb.
