Professor Ma was stumped by Zi Yi's question and answered, "This can't be restored at all."
"Why not?" Zi Yi was a little surprised. "Don't tell me such a simple restoring reagent is yet to be invented?"
Professor Ma: "…"
If not for the fact that he had been working as an archaeologist for decades, Professor Ma would have thought restoring oxidized cultural relics was easy to accomplish based on how Zi Yi said that.
He did not know whether to laugh or cry and he purposely said, "In that case, does Student Zi know of the method to restore the oxidized area and at the same time, not damage the cultural relic?"
"Yes, I do." Zi Yi mentioned several different types of chemicals. "After mixing these chemicals according to the correct ratio, add in a natural anti-corrosion grass and the oxidized area can be restored."
Professor Ma: "…!"
