As Lin Feng refined it, another month passed.
At the same time, his strength had also improved considerably during this period.
He had now advanced from the Mid-stage Nine-star Dou Sheng realm to the brink of a breakthrough.
As long as he took that final step, he would break through the barrier and enter the Late-stage Nine-star Dou Sheng realm.
However, the vast amount of blood surrounding his body had also grown much scarcer.
