Chapter 724 - 722 Tracking the Lich
Hearing that Rex needed to find a way to keep track of the lich. He decided to try and technique that he had once used before but was deemed useless because he was body cultivator at the time.
"Forced Qi into this coin"
Rex spoke as he tried to force Qi into the coin. This was the first step of the process.
"Remember a symbol on the coin"
Rex forged an arrow that would point in a certain direction.
"Qi Technique: Forced Tracker"
As the finishing touches were put on it. Rex felt a massive headache from trying this Technique. It was not because it was truly mind breaking, it did not consume a lot of Qi, but it forced the concentration of the Technique to the upmost limit of all cultivators.
First, making the symbol with the Qi is not hard but not easy depending on the symbol. Forcing the Qi into the coin or other small object is rough but not very long.
The truly hardest part was for the Qi to be laced into the symbol and for it to be set in before everything goes black and the cultivator fails the Technique.
