Li Tian naturally wouldn't reject Nangong Zhen's suggestion. He nodded and walked out of the room with a pale face. He then took out two vitality Dragon pills and swallowed them.
To Li Tian, consuming his blood essence wasn't a big deal. Even if he used up all his blood essence, he could recover quickly.
Previously, when he was practicing the blood-ignition Dark Demon transformation, he would often use up all of his blood essence. In the end, he would be able to recover quickly every time without any accidents.
Of course, only Li Tian could do this. If it were other cultivators, they would probably need to rest for half a month before they could recover.
At the end of the day, it was all because of his extraordinary physique. As long as he had enough qi and blood, he would be able to condense blood essence at a terrifying speed.
