The moment Chu Feng said those words, the old man's heart trembled. He thought that his identity had been exposed.
Unexpectedly, Chu Feng did not think about anything else.
It was mainly because of Chu Feng's preconceived idea.
Who would have thought that such a sloppy and lazy old man was the famous Grandmaster Mo of the Heavenly Book Academy?!
Chu Feng found it quite strange. Why did an old janitor have such a solid foundation in forging?
However, because he had just arrived at the Heavenly Book Academy not long ago, he did not know much about it. In addition, he had always heard that everyone in the Heavenly Book Academy was a genius! Those who were not geniuses could not enter at all!
From this perspective, it seemed reasonable for an old janitor to have some talent, right?
After all, he had lived for so long.
As time passed, even a sow could climb a tree!
