"At least forty or fifty years, and at most one or two hundred years."

The woman in yellow dress had a bit of anticipation in her bright eyes.

In the next few months, a woman in yellow was busy refining elixirs.

Because most of the materials are available to several elders on the island, after the water content of Tianyihun is enough, the woman in yellow began to refine the Tribulation Pill.

The Tribulation Pill has two functions.

First, improve the breath of the robbery, thereby reducing the power of the robbery to a certain extent.

This is the ability of ordinary tribulation elixirs, which is excellent if it can weaken the power of the heavenly tribulation by one or two.

The second one is to resist the inner demon disaster.

The second function is the best tribulation pill, which requires Tianyi Soul Water and Jade Tianhun Fruit, which is extremely difficult to achieve in one world.

It is said that the second tribulation pill, looking at Xianyun Island, has only been refined into one since ancient times.

During the elixir of a woman in yellow shirt, Yang Fan made a request to observe.

Alchemy is the exclusive secret and is generally not allowed to be watched by others, but the woman in yellow agreed with a smile.

Half a year later.

Hiss bang—

A stream of blue smoke exploded over Elder Huang's cave.

"Failed..."

The woman in yellow looks a little ugly.

The materials he prepared can only be refined twice at most.

Yang Fan pondered: "Yang's true fire is miraculous in refining alchemy, and may help the elders."

The woman in yellow nodded half-believingly.

However, facts have also proved that in Yang Fan's body, whether it is the Taixu Heavenly Fire or the Consecrated Pure World Flame, they are excellent true fires for alchemy.

Three months passed in a flash.

The woman in yellow dress had a soothing eyebrows, with a happier look: "I didn't expect that Fellow Daoist Yang would have such a brilliant alchemy technique."

Yang Fan smiled without saying a word. He also learned a lot from it, and also learned the methods and procedures for refining the Tribulation Pill, as well as the material formula.

In other words, Yang Fan will have certain confidence in the future and independently refine the tribulation pill.

He is now helping the woman in yellow clothes, and he is also accumulating the foundation of experience for himself in the future.
