Even though Fei 'er did not understand why Zhao Hai was so confident, he knew that Zhao Hai was very strong and would not joke about this matter. Therefore, Fei' er only nodded and did not say anything else.
On the other hand, the demonic Dragon King understood why Zhao Hai was so confident. Yesterday, they entered the space through the demonic city. Today, they came out and arrived at the aklaya Mountain line of defense. No matter how stupid he was, he understood that the space had a teleportation function. Thus, it made sense for Zhao Hai to say this.
What touched the demonic Dragon King the most was that he knew exactly what Zhao Hai meant by " something to take care of ". There was nothing left for Zhao Hai to take care of on the ark continent. All Zhao Hai had to do was to head to the demonic realm and bring the demons into the space.
