Chapter 981: 992

Tian Lan Hua, ten thousand year old snake strain, all turned into pure liquid medicine, and Chen Feng's mouth was slightly raised. All the three auxiliary medicines had been refined into liquid medicine, and they were constantly refined in the Dan Ding. The only impurity left in the liquid was completely stripped off, and Chen Feng stopped refining it!

But at the same time, Chen Feng did not dare to have any interruption in his movements. Suddenly, a piece of black wood appeared in his hand. The electric arc around the dark curtain made Chen Feng's palms crisp and numb!

Chen Feng's mouth slightly raised, looking at the thunder iron wood heart, he said: "it's amazing, this thunderbolt iron wood core is going to become our cultivation resources today!"

With that, Chen Feng directly threw the thunderbolt iron wood core in the Dan Ding, and suddenly a chaotic fire was wrapped up. Chen Feng's eyes could see that the thunderbolt iron wood core could not resist the burning of chaos fire when facing the chaotic fire!

As if, this is wrapped by chaos fire, burned into slag, forced out of the liquid medicine is inevitable!

Chen Feng mouth slightly Yang, quietly urged the chaotic fire to roast the hard skin of thunder iron wood heart!

The outer skin of this thunderbolt iron core is extremely hard and dense bark forged by the force of thunder. Besides, there is a layer of thick resin outside, which forms a very hard pulp film layer after curing!

Although this kind of film is very hard, after being burned by a strong enough flame, the pulp film will become soft and even become a combustion supporting material to help enhance the power of the flame and help refine Lingzhi Baoyao!

After 30 minutes, Chen Feng's eyes suddenly burst out with a touch of pure light. Looking at the outside of the thunderbolt iron wood core, there is a layer of grease like substance. Chen Feng knows that this is the resin formed after the hardened pulp film layer outside the thunderbolt iron core softens!

This resin is very flammable. It was ignited by the fire of chaos when it was just formed. Suddenly, the fire of chaos in the red dragon of Dan Ding was burning more vigorously and blazing!

Chen Feng's mouth slightly raised, palm suddenly virtual grip, the fire of chaos in the cauldron more burst, as if with all his strength to roast, refining this thunderbolt iron wood core!

This thunderbolt iron wood core is a sacred object formed by the tempering of thousands of times of thunder. It is very hard. Even if the hard resin outside is burned and softened, it can't be relaxed!

The hardest part of the core is wood!

The tree core itself!

A towering ancient tree, only a small arm length of the tree core, and after tens of thousands of times of tempering Tianlei tree core plus the wax of oil, it becomes a thunderbolt iron wood core!

And at this moment, it is the most difficult place to be refined!

But Chen Feng now is to increase the firepower, although the core of the tree is hard, but still a little bit blackened, and even some places have a little spark!

"Hum, it's stubborn. I really think I can't refine you?"

Chen Feng is not satisfied with the current refining speed and directly increases the temperature of chaos fire to the highest level!

Boom!

Just hearing the sound of a flame explosion, the red cauldron and the dragon were all melting at this moment. Chen Feng was shocked and quickly lowered the power of the chaos fire, which ensured that the Dan Ding could still be used!

This time, Chen Feng did not dare to be impulsive again. He was regular and refined a little bit!
