After pondering for a while, Su Yu took out a severed finger.
It was cut off from insect ancestor’s hand by ancestral Dragon Yiyu.
When Su Yu left, Ancestral Dragon Yiyu took it with him before it fell into Su Yu’s hand.
After a brief inspection, Su Yu found that there were about ten drops of pure insect ancestor’s blood inside.
The blood in a living being’s body was divided into pure and thin drops.
There were only so many pure blood, and each drop was less than the last.
The ancestral insect had gone through an era, and every day, a drop of blood was dripped into the cauldron. Where could he get so much pure blood?
What he dripped was the thin blood that ran under his skin and could be expelled from his body at any time.
The essence contained was less than one-ten-millionth of a drop of pure ancestral blood.
Every drop of the ten drops of essence blood in his finger should be able to activate the ancestral dragon feather for an instant.
