The way of the rat is difficult, more challenging than ascending to the heavens.
The narrow rat passages allowed only for crawling on the ground, and if Zhou Chun were alone, just crawling to the rat nest might take him several "two hours".
Fortunately, he was not alone.
He turned the "Golden Cauldron Profound Light" into a membrane of light to shield himself and then tied a rope around the Silver Lightning Python Baibai, letting it drag him along.
Although this appeared quite undignified, the speed of advancement was incredibly fast.
The troublesome rat passages posed no obstacle to serpents, and they only traveled a bit slower than rats themselves.
Because of this, Zhou Chun experienced a sensation of rapid advancement underground.
He was like a person being dragged by a warhorse, clinging to the rope while being rapidly pulled through the twisting subterranean rat passages, his body swinging and slamming into the hard cave walls countless times.
