Chapter 886

Penglai Immortal Mountain is very large, with many strange flowers and fruits growing on it, and the vegetation is extremely lush.

Even with the help of Zinu, the Da Siming, the Shao Siming, Xiaoyi, and some Yin-Yang School disciples, it is a difficult task for Duanmu Rong and the others to identify the properties of many plants in a short time.

After Su Xuan gave this task to Zinu and the others, he also realized this.

Consequently, he could only take action himself.

Among the Seventy-Two Earthly Transformations, there is the art of medicine. Back then, Su Xuan relied on this art, combined with the art of ingestion, to refine I don't know how many medicinal materials. It can be said that he initially relied on medicinal materials to rapidly improve his strength.

Of course, in this process, one has to mention the importance of a financial backer.

Relying on himself alone, although he could also collect many medicinal materials, how could that be as fast as relying on a dynasty? Initially, the Han Wang provided him with a large batch of medicinal materials.

Later, after the Han Wang died, he killed Ji Wuye and mastered the Yemu, and with the help of the Yemu's power, he also harvested many medicinal materials.

And the true peak period of his strength improvement was when Su Xuan came to the Qin Guo.

The Qin Guo is powerful, and many precious medicinal materials could be collected by the King of Qin. Later, Qin destroyed the six states, and the treasures in the treasuries of the six states all belonged to the Qin Guo. The medicinal materials among them were all handed over to Su Xuan by Ying Zheng in one go.

In the process of refining these medicinal materials, Su Xuan's understanding of the Dao of vegetation had reached an unprecedented realm.
