Shadow on the Moon

Lu Changsheng, who transmigrated as the apprentice of Elixir Garden, originally wanted to work hard to become a divine doctor who could save people. But when he began to practice martial arts, he found that every time he practiced martial art to perfection, he could improve his insight.
Moreover, it seemed that his insight could improve ceaselessly. Lu Changsheng wondered where the upper limit of his insight was.
Unremarkable: slightly better than waste.
Preliminary: an ordinary person
Potential: the potential is shown
Whiz: capable of a lot!
Renowned: sharp and invincible!
Genius: the name of genius spreads to the world!
Legend: establish a sect and be the first!
Saint: shock the world!
Unprecedented: dominate the whole world!
Top Insight: Unspeakable, invisible, and inaudible!

Top-Class Insight: Start with Basic Fist Techniques

Lu Changsheng quietly returned to the Miracle Hand Garden.

He took out a porcelain bottle from the secret compartment and poured out the black worms inside.

Lu Changsheng had caught the black bug from a dead body in a ditch outside the city. Now, he was sure that it was the black bug in Old Man Wang's body.

He poured the black bugs on the table and found that they were indeed dead.

"The strange black bug is closely related to the demonic cultivator Old Man Wang. Once Old Man Wang dies, these strange black bugs will also die."

Since these strange black insects and the demonic cultivator Old Man Wang were in the same boat, they could also detect whether Old Man Wang was dead or not from these strange black insects.

Lu Changsheng put the black bug back into the bottle.

If the black bug resurrected after some time, it would mean that Old Man Wang had also resurrected.
