Tang Yin pondered for a moment before making his decision.
He bought 2 small vials of Void Lightning's Lightning Essence, 2 small vials of Soul Lightning's Lightning Essence and 1 small vial of Holy Lightning's Lightning Essence.
The reason why he bought 2 vials for each Lightning Essence instead of 1 was because a small vial was only around half of what he needed. The Tribulation Lightning's Lighting Essence that he had was twice the quantity of 1 small vial of Lightning Essence.
So, purchasing 2 vials of Lighting Essence for each type of lightning was equivalent to the quantity of Tribulation Lightning's Lightning Essence that he possessed.
Unfortunately, he did not have enough contribution points left, so he could only purchase 1 small vial of Holy Lightning's Lightning Essence.
Tang Yin then checked his Personal Identification Token.
