บท 401: Training in the Dragon Abyss

The level of difficulty of making a breakthrough to Heaven Master was higher than Su Yu had expected!

If he was still unable to make a breakthrough even after swallowing four Heaven Masters, the difficulty of overcoming this obstacle must have been extreme. Moreover, even after he had swallowed tens of thousands of people and massacred all the forces of the North Continent's Alliance, he was still unable to make a breakthrough.

By now, Su Yu felt hopeless. This gap was impossible. If slaughtering the whole north continent wasn't enough, what would he have to do to break through successfully?

However, he did feel that he was very close to making a breakthrough. His only hope seemed to be to go to the Dragon Abyss of the Nine Underworlds and rely on chance to make a breakthrough!

Standing atop the ocean, Su Yu looked back. He shot his cold eyes toward Long Feiyu and the Four Great Ancient Clans, who were only 10,000 feet away.
