After opening his second gene lock, Han Sen noticed his super spirit mode was considerably more powerful. While this was advantageous for a number of obvious reasons, there was a certain drawback that weighed on his mind.
This mostly stemmed from the fact that his fitness hadn't risen to coincide with the second gene unlock. With an even greater burst of strength, using super spirit mode could very well last even less time than it had before.
So Han Sen continued practicing the Dongxuan Sutra, wanting to fill up his geno points. But from his current locale, his options were limited. He had to wait for the shelter to arrive at the edge of Thorn Forest before going out to hunt and obtain meat. All he could do for now was harvest spirit geno points to bolster his elemental powers and resistances.
