According to Han Yijian and the others, the 10,000-year Stalactite was able to improve cultivation without any side effects. Furthermore, it could purify the body, strengthen the body constitutions, as well as heal any injuries.
Su Mo had no idea how effective it was, so he swallowed all of it except a few drops which he kept for Li Feng.
After entering Su Mo's body, it turned into a warm current that purified his body and flooded his elixir field.
Streams of black impurities were then excreted by his pores. Although his physical strength did not increase, his body constitutions had improved and became better for cultivation.
Su Mo's cultivation rose quickly at the same time, from Late Lv 6 True Spirit Realm to Peak Lv 6 in the blink of an eye. It still showed no signs of stopping and loosened his cultivation bottleneck.
Concurrently, attacks from Yuwen Jun and the rest were already right before him.
