The old monk intervened to prevent Xu Fan from killing Huang Siyuan not out of hostility towards Xu Fan, but as a form of protection for him.
Though unknown to each other, even though the Buddhist sect is compassionate and strives to save all beings, the old monk is not a person overwhelmed by benevolence. Especially at a cultivators' gathering, no one would offend a giant like the Huang Family for someone unfamiliar.
However, Xu Fan used his performance to evoke a fondness for talents in the old monk.
With a realm of Entering Dao Realm Peak, he could wield the power of the Middle Stage of the Vajra Realm!
With a realm of Entering Dao Realm Peak, he could even forge a Mechanical Warrior comparable to the Late Stage of the Vajra Realm!
Moreover, most importantly, Xu Fan is not even twenty years old!
Such a monstrous talent, once grown, is almost destined to become a strong person at the Zhiwei Realm! He might even have the qualification to reach higher realms!
