In fact, at that time, after Zhou Tian put in a period of effort, he really achieved some results.
At the original pitfall location, every time Zhou Tian cleared out zombies, that area no longer saw any zombies appear. Only after Zhou Tian dug further would new zombies emerge at that spot.
Thus, as Zhou Tian repeatedly cleared out zombies from that pitfall location, he inevitably deepened the pit he was excavating. Eventually, through the effectiveness of Zhou Tian's actions, he truly made an unexpected discovery while digging.
Facts proved that Zhou Tian's decision at the time was fairly correct.
