As Tang Yin climbed up the steps of the Heaven Ascension Peak, the pressure increased exponentially. However, this was not a problem as he just devoured the Spirit Qi which pressured him. The amount of Spirit Qi he devoured increased on its own as the pressure intensified.
Tang Yin's proficiency in condensing spirit veins kept on increasing, it did not take even a minute to condense a spirit vein. The time required to condense a spirit vein kept being reduced.
When Tang Yin reached the 250th step, he reached the threshold of the 899th spirit vein. He would reach the 9th stage of the Spirit Vein Condensation Realm once he condensed this spirit vein.
Scattered Soul Daoist and the other cultivators were not too far ahead, only at the 280th step. They had noticeably slowed down. The pressure was not an issue for Tang Yin, he could reach the 1000th step if he wanted to. All he needed to do was to Devour the Spirit Qi which descended upon him.
