The hatred of killing a son

Ling Han kept studying Niu Er's horn. After so many days, he naturally gained considerable understanding of it.

The horn was formed from all the concentrated energy of the Herculean Iron Bull Race. From a certain point of view, this was a Celestial medicine. In fact, it was even stronger than Celestial medicines.

Ling Han did not use it in the concoction of alchemical pills, because he was still not very familiar with the Celestial medicines of this world, and could not use it effectively.

Hence, he made some changes, and decided to just do a simple refinement of the two bull horns, extracting the essence that was contained inside.

After returning to Tang Yuan's courtyard, he began this task, and because he feared that he would be disturbed, he entered into his Spatial Celestial Tool.
