Copying this is simply too lowbrow.
Beyond their literal meanings, every stroke and line in the carvings of this room, left behind by Dugu Qiubai, also embody the profound essence of Sword Dao. Compared to copying, making rubbings could certainly maximize the preservation of the enormous value of these carved inscriptions.
After learning that there were carvings left by Dugu Qiubai in this room, Ye Weiming was prepared with more than just these items.
In addition to all the items needed for the rubbings, he also brought hammers and chisels.
If the System hadn't warned him that attempting to destroy these carvings would incur a counterattack from the latent Sword Intent within them, he even planned to prise these carvings off the wall.
He would cram them all into his bundle and take them back to the Constabulary!
