Compared to the opportunities in the 300 small worlds, the opportunities in the 3,000 large worlds could be said to be both dangerous and opportunities. Moreover, the danger was relatively greater.
Under normal circumstances, no high-level cultivator would attack a high-level cultivator who had entered the 3,000 macro worlds, but what about under abnormal circumstances?
For example, if some high-level cultivators who entered the 3,000 worlds earned too much world origin energy, they would attract the jealousy of some high-level cultivators. Or if some high-level cultivators had special secret techniques to extract the world origin, then these high-level cultivators who entered the 3,000 worlds would be in danger.
Even with Zhu Wuyang's strength, he didn't dare to be careless. He specially set up layers of spiritual arrays on a hill to protect himself. Even the Qianyuan Sword Saint and the Wuque Grand Sage were called over to protect him at any time.
