Everyone, upon seeing the high tower, showed a look of amazement.
It's not that these cultivators lack knowledge; on the contrary, all the cultivators here come from various superpowers and are the most knowledgeable group in the Cultivation World.
The high tower in front of them is made from ordinary rock, but its surface is covered with runes.
This is what surprised the cultivators because ordinary rocks simply cannot withstand the engraving of runes.
Li Yuanba was also watching. Sharing artifact refining and formation abilities with his original self made him more aware of the material quality required for runes.
The spiritual treasures he refined were all based on materials of Fourth Grade Top Quality, and only such materials could withstand billions of micro-engraved runes.
Even with Li Shiming's artifact refining skills, he could not engrave runes on mundane rock, let alone so many runes.
The high tower before him stood over a hundred meters tall, resembling a pillar.
