Qi Ming fell silent. According to what Celestial Venerable Ying had said, if Qi Ming wanted to find a method that could allow the Three Pure Dao Scripture to fuse, he had to go to the Immortal King grotto-heaven.
The Immortal King grotto-heaven was in the Central World. The Central World was the territory of the immortals, and the entrance to the Immortal King grotto-heaven was at the top of the Central Divine Mountain.
It would probably be very difficult for Qi Ming to enter the Immortal King grotto-heaven.
With Qi Ming's status, if he accidentally leaked it, he would probably immediately be surrounded by the immortals.
Additionally, the Immortal King grotto-heaven was filled with invisible killing intent and nirvana tribulation qi. Even existences at the Tribulation Transcendence realm would probably die if they were surrounded by these tribulation qi and killing intent. Only those at the Mahayana realm could truly withstand it.
