When a dog was pushed into a corner, it would become desperate and do anything within its power to resist. And that best described Luo He's current situation. Luo He was just a dog that was pushed into a corner and could only helplessly resist.
Although Deus admitted that Luo He was stronger than Luo Huang, it was just that. In the end, Luo He's strength was just stronger than Luo Huang's but not strong enough to resist Deus.
Because of that, Deus didn't take Luo He too seriously since Luo He wasn't worthy to let Deus show his full power.
Deus no longer had any interest in stalling his battle against Luo He. Because of that, Deus forwarded his hand towards Luo He as he used his bone manipulation to control the bones inside Luo He's body.
But much to Deus' surprise, the aura within Luo He's was strong enough to resist his bone manipulation. Because of that, he couldn't pull off the same move he used to instantly kill Luo Huang.
