Refining medicine not only requires the consumption of fighting energy, but also a large amount of soul power.

This process of consumption and recovery naturally results in a gradual increase in soul power.

“Hey, once we get the Azure Lotus Earth Core Fire, can we go look for the Fallen Heart Flame?”

Gu Fengchen had long wanted to visit the Black Horn Region and Canaan College.

In addition to the Fallen Heart Flame, the Netherworld Poison Fire, which ranks 20th on the Strange Fire List, is also what Gu Fengchen has coveted for a long time.

He himself used the [Seal of Taotie] to harvest the poison-attribute fighting spirit of the Little Medical Fairy, and this Netherworld Poisonous Fire, combined with the poison-attribute fighting spirit of the Evil Poison Body, would be absolutely invincible.

This Netherworld Poisonous Fire is the fire that existed in the ancient Netherworld Poisonous Swamp.

After being infected by the poisonous miasma that covered the sky for thousands of years, the flames burned the endless poisonous miasma. It took hundreds of years to become a spirit, and it took thousands of years to take shape. When it was completed, its color turned green, and it was like a will-o’-the-wisp traveling through the poisonous miasma. .

Since the flame itself is fed by poisonous miasma and is highly toxic, if it is contaminated by a spark for a moment, the body will be poisoned, let alone being swallowed and fused.

This kind of strange fire is extremely dangerous. Only those with a poisonous physique like the Eternal Poison Body and a domineering physique like the Three Thousand Flame Body dare to absorb this kind of strange fire.

According to legend, this Netherworld Poison Fire takes the shape of a butterfly, and the flame is filled with poisonous strange fire. It is lavender in color, and is formed by absorbing strange poisons between heaven and earth. It is extremely powerful, and even a little bit of it will make people live a life worse than death.

After I have conquered the Netherworld Poison Fire, I will try to use it to help Little Medical Fairy improve her realm.

Just like the time passes in the mountains, no one knows how much time has passed in this dark and dark underground ancient dust.

After a few days had passed, Gu Fengchen suddenly opened his eyes, and his powerful soul power condensed into a beam and drilled deep into the ground.

Through the continuous tempering during this period, his soul power has grown very well and has really improved. Although this process is very boring, Gu Fengchen is very happy that it can increase his soul power.

In this world, soul power is the most difficult thing to increase.

You know, to improve soul power, you either need some opportunities and insights, or extremely precious treasures from heaven and earth, but most of the improvements in soul power depend on the enhancement of strength and the gradual accumulation of time.

Gu Fengchen felt that this kind of opportunity was quite good, so even though he hadn’t found the Green Lotus Earth Core Fire yet, he wasn’t in a hurry.

Now that he had this opportunity and found such a good way to strengthen his soul power, he would naturally not let go of the opportunity.

Of course, Gu Fengchen also knew that this growth pattern was not suitable for long-term use. He could clearly feel that the growth of his soul power had gradually slowed down in the past few days.

In addition to the enhancement of soul power, Gu Fengchen discovered that the process of recovering soul power after each use up of soul power was also a process that allowed his understanding to continue to improve.

With his current soul power and comprehension, he could easily practice the earth-level techniques.

……

Finally, hard work pays off. After three days, Gu Fengchen finally found the place underground with the most abundant fire energy.

This place filled with fire energy is, naturally, the birthplace of the Qinglian Earth Core Fire.

Gu Fengchen took back all the soul power that was radiating like a silver snake. After entering the underground, he almost exhausted his soul power every day searching. Gu Fengchen’s soul power has increased by about 10% compared to before. (End of this chapter)
