Lu Chen was shocked and instinctively tried to withdraw his hand.
But at that moment, it felt as though his hand had grown into the jade bottle!
He couldn't imagine how his hand had entered the bottle without any sensation through such a small opening!
What's more, Lu Chen found that his hand was still beyond his control!
At the same time, within his Dantian, all his Spiritual Power naturally transformed into Fire Spiritual Power, flowing continuously towards the jade bottle!
While he tried to pull away, he also feared his body might be drained by the bottle.
It was as if there was a wolf in front and a tiger behind, a dilemma with no easy solution!
Yet at this moment, Lu Chen was surprised to find that his body was beginning to change!
Originally, he needed to cultivate the Heaven-Breaking Spiritual Method to transform the Spiritual Energy in the air into his own Spiritual Power before infusing it into the jade bottle to form Spiritual Liquid through the mouth of the bottle.
