Since he had cultivated the Guixu Grand Dao, Chen Nianzhi no longer hesitated.
He immediately began using the Guixu Grand Dao as a blueprint, integrating it into his sixth blank True-Spirit Divine Mark.
With a ready-made blank divine mark and the Guixu Grand Dao, cultivating the Guixu Divine Runes was not slow. Mere centuries later, Chen Nianzhi had thoroughly cultivated the Guixu Divine Runes.

"This Guixu Divine Mark can devour nearly all enemy attacks."
Chen Nianzhi murmured inwardly and continuously tested the limits of the Guixu Divine Mark. In the end, he discovered in astonishment that the power it could devour was roughly equivalent to the limit of his physical defenses.
In other words, so long as an opponent's attack did not exceed the limits of Chen Nianzhi's defenses, all damage received would be absorbed.

Although early-stage Hunyuan Emperors could not inflict much damage upon Chen Nianzhi, if an early-stage Hunyuan Emperor unleashed their full strength, they could still injure him to some extent.
If he were besieged by a group of early-stage
