The creator of the Secret Realm not only set up challenges but also set up extremely cruel ones.
To inherit the corresponding legacy, one either needed to possess the Sealing Heaven Flag, otherwise, failure meant death.
Neither Wang Sheng nor Luo Tian doubted its authenticity.
If someone from the Tenth Realm truly wanted to kill someone from the Ninth Realm or even lower, it wasn't difficult at all.
Luo Tian was bewildered; he had never anticipated such a test.
The Sealing Heaven Flag was merely a protection from death.
It was not hard to predict that the difficulty of the test would not be low.
There was a high probability that those from the Ninth Realm would not pass.
Similarly, he could guess that if one failed once, the Sealing Heaven Flag would definitely be taken back, and the treatment thereafter would be the same as for everyone else, with no difference.
He even didn't know whether he could leave after using the Sealing Heaven Flag.
