Boris looked at the grandson before continuing his explanation. "As I have already said. The entire Imperial Royal Palace is protected by an extremely powerful defensive dome. It is strong enough to block the attacks of Seventh-Order cultivators. Only the attacks of an Eighth-Order cultivator are capable of weakening the barrier."
He paused for a moment before adding another important detail. "Even then, an ordinary Beginner Eighth-Order cultivator would not be able to break it with just a few attacks. It would require repeated strikes over a period of time before the defensive dome showed any signs of weakening."
"Is it really that strong?" Aditya asked, unable to hide his surprise.
Boris nodded. "I was not the one who created this defensive dome. It was built by one of the Founding Fathers of the Celestial Dragon Empire. At that time, its purpose was simply to protect the Imperial Royal Palace, which was much smaller than the one you see today."
