Review Detail of MarkoCapco in I Can Track Everything

Im at ch 400 and its gotten pretty messy at this point of his ascension to the immortal world. It was great at the start but everything changed after he got that mark from heaven. He became scared of picking up treasures because he doesn't want to be killed in the lightning tribulation, so he just lets go of all the treasures he comes across which is a waste because wtf is the point of the system then?Next, even after 400 chapters, his power is extremely low. This is the first time Im seeing an MC whose power is literally on par with the small fries and doesn't dominate his cultivation realm. He can defeat people on the same cultivation realm (cant be higher than 1 minor realm) barely. His greatest strength which is the divine sense is so useless because everyone in the upper world has divine sense protecting treasures so at this point, MC is pretty much just an average cultivator who is extremely afraid of picking up treasures, the system is useless, and the only thing salvaging this novel is the fact that MC is street smart.
