'What is it doing?' Yu Nianzhen wondered but he didn't need to wonder for too long.
A few breaths after the sword entered the pool, the gold source essence began to boil.
A vortex appeared in the middle of the pool and a sucking sound reverberated in the surroundings.
'The gold source essence should be good for the sword.' Yu Nianzhen thought with a little regret.
He originally planned to take the essence for his own use.
Unfortunately, his sword had other plans and was greedily sucking the essence.
Within an incense stick, the gold source essence disappeared and a sword floated in the middle of the pool.
The sword's blade was brighter than before and its edge appeared extremely sharp.
"I will take you back to warm." Yu Nianzhen said and the sword turned into a silver light.
It entered his dantian and sunk into his qi ocean.
