Regarding the dangers caused by the Tao Realm, heaven and earth have made an instinctive response. This is the origin of the invisible shackles Qing Yu speculates about.
Although it's just one man's opinion and there may be errors Qing Yu doesn't know about, at least half of it should be correct.
To prevent the extremely destructive Tao Realm from reappearing, heaven and earth have placed shackles on this realm, causing martial artists to reach the peak of the Divinity Realm with nowhere further to advance, thus naturally calling this peak the Realm of the Supreme.
Simply because when martial artists reach this realm, they have reached the ultimate.
"The Dao Ancestor should have achieved the Tao Realm before the shackles appeared. As for the Buddha..." Qing Yu mused.
The Buddha's enlightenment occurred thousands of years ago. At that time, the shackles should have already appeared. To achieve the Tao Realm, he would have had to use one of the two methods mentioned earlier.
