After Gu Ding was leveled up to the fourth level of Ultimate Arts, his regenerative ability allowed him to use Ultimate Arts Level 4 without it taking a toll on his body.
A Cell Index of 100 points paired with double the Combat Armor and twice the strength of his Ultimate Arts Level 4 ensured that Gu Ding's ability was comparable to that of a martial arts practitioner with a 400 point Cell Index. This also meant that he had combat effectiveness of a Rank 5 Gene Body.
However, his opponent, Cooper, was a proper Rank 6 Gene Body. He had evolved so much that he was now ruling his own kind. On land, he was undoubtedly the king of the planet. However, there were much more powerful beings in the sea. If he had not awakened the memories of the host, he would have undoubtedly tried to battle the powerful beings in the sea by engulfing everything to make himself stronger.
