In fact, after Zhou Tian successfully executed a sneak attack, although it didn't directly inflict severe damage upon the God of the Burrow Spiders as he had hoped, it did manage to injure him somewhat given Zhou Tian's strength.
Even though the injury wasn't life-threatening and the impact on his strength was not significant, it was undeniable that Zhou Tian's attack hurt the God's pride. Given his power and status in this world, when had he ever suffered such humiliation? Thus, while the physical injury was one thing, it was the hit to his pride that drove the God of the Burrow Spiders into madness.
Regardless of the reason, after Zhou Tian injured the God of the Burrow Spiders, their relationship was immediately defined. If there were no accidents, the God of the Burrow Spiders would inevitably see Zhou Tian as a mortal enemy; and given the situation at the time, if Zhou Tian's performance had been slightly inadequate, he might have ended up being killed.
