The earth's crust had once been torn by the spatial crack and was now loose and soft. But the lower one went, the harder the earth became. Even with the Abyss Ancient Sword to open up the path, Zhang Ruochen still kept slowing down.
It wasn't the rock layer anymore. It was more like jade and metal.
In the end, Zhang Ruochen stopped completely. A layer of dark gold appeared under his feet. It looked like some mineral or something formed by condensed energy.
Cutting down with his sword, the blade created a crisp sound on the ground. Sparks flew. Upon closer inspection, he saw that a thin layer of golden light had appeared on the ground. It actually forced the Abyss Ancient Sword aside.
"There's really something harder than the Abyss Ancient Sword in this world?" Zhang Ruochen shook his head. Lifting a palm, he pressed onto the ground and released his Spiritual Power.
