Endless wind and sand erode this once glorious land, and after experiencing the turbidity of the years, some only the vast sea of sand remains, full of traces of desolate and sad years.

Whew-

"Finally came out, take a break, I really can't walk!"

Spanning half of the desert, Yechen's whole person has long been exhausted, if it weren't for the only remaining heart fire in his heart still burning, if it wasn't for that unyielding faith, how could he have come here.

I took out the last water bag, took a sip and it was gone, and there was not much left when I stepped on the last sandy field. The last bite was left under his own strong insistence, and men just have to learn to control their desires, which Yechen himself admires.

The desert is like an invisible barrier with the outside world, the inside of the barrier is lush, vibrant, and the continuation of eternal life, but on the outside is death, endless desolation, and the end of life with traces of death!

"The desert is lonely, and the sun sets on the long river!"

Before noticing, it was almost sunset, and Yechen lay on a high tree, his head resting on his hands, and his eyes looking into the distance. When the last rays of the sun shone and the sun disappeared on the horizon, Yechen's face felt a little lost......

Got up and stretched, then groped his way through the night to find a more secluded cave. I found some dry firewood, made a fire in the cave, and then I was ready to get to work.

I took out the Dan furnace from Na Ring, although it was very old, and it was constantly eroded by wind and sand in the desert, but it was not destroyed, indicating that its material was very good.

"This is supposed to be the bronze furnace, the bronze performs very well, and... The thermal conductivity is extremely high, and although the surface is slightly worn, it does not affect the production of hidden weapons!"

First of all, from the chemical point of view, it has not changed for such a long time, it should belong to an inert bronze material, and this aspect alone is enough to keep it from oxidizing. And physically, its structure and texture are also very good. Yechen looked at the Dan furnace for a long time, thought about it repeatedly in his mind, and then took out the heart source vibranium.

"Whew-"

summoned the Fallen Heart Flame, but I saw that the vibranium was gradually softening, what is the principle of this?

"It's... Vibranium will soften when it gets close to the fire, what's the situation?"

I didn't expect to see such a scene, a physical phenomenon that is difficult to explain. Even the physics knowledge that I have learned before cannot explain this phenomenon. Yechen ponders, this is a novel discovery.

"It's called the Law of Molecular Transformation!"

Just as Yechen was thinking, the system said the name. Just by hearing the name, you know that it's not a simple thing, and besides, Yechen has never heard of it.

"What is the law of molecular transformation?"

Yechen asked curiously.

"In a certain situation, if two incompatible objects, when they reach a certain distance, the substance in the body will interfere with the substance in the other body, thus changing the structure of the molecule, which can be more or less, long or short, dense or sparse, of course, there is no further interpretation of this law in my database, so I can only tell you this!"

In a particular situation, what is this particular situation, and it is also a place that Yechen is very concerned about, although it is impossible to speculate at the moment, but with this law, it saves himself a lot of time.

Since the vibranium has become soft, the initial stage of alchemy is simple, and the rest is the four stages of refining, removing impurities, forging, and refining. And forging and refining are carried out at the same time, so there is no order.

"But to be honest, I think you should have a domineering name, otherwise I don't know what to call you, and... Your voice needs you a good name even more!"

Yechen said with a smile as he moved.

"I don't have a name, I'm just a system without emotions, and you don't need to remember anything about me!"

This kind of rejection is the first time Yechen has experienced, after all, I haven't had too close contact with girls before, so I'm a little lost in my heart.

Put an appropriate amount of Heart Source Vibranium into the alchemy furnace, and then release the Falling Heart Flame, "Then how about I give you a name?"

"There's no need, and I don't need to!"

The system firmly rejected Yechen's request, he never had a name, what was the use of asking for that thing? it was just a title, not something that needed to be there.

"What don't you need, I... Let's call you a little thorn, although I know you only in a mental state, but I can make friends with all things, and you are also my friend!"

Dripped a part of the juice from the poison pill into the pill furnace, and he needed to express his true thoughts in his heart, instead of going on so indifferently.

"Anyway, I only belong to the virtual, you can call it however you like, I don't care!"

The two argued for a long time, and Yechen focused his attention on the alchemy furnace. Anyway, in her own opinion, Xiao Thorn is a knife mouth tofu heart, maybe she hasn't learned how to have a human emotion, but as a system, her learning ability should be unique and super strong.

Summoning the Origin Fire of the Fallen Heart Flame, due to the state of the Heart Origin Vibranium, it is now only necessary to start from the refining stage. Slowly refining that giant venom juice into the Heart Source Vibranium and letting it slowly become a part of it is an extremely time-consuming process. And among the four stages, refining and melting is also the most consuming of fighting energy, so you must make good use of every trace of your fighting energy as much as possible, and the so-called things should be used to the best of their ability, which is the truth.

"Not enough, this is not enough ......"

Just relying on a little bit of indoctrination of vindictive spirit, the best effect cannot be achieved at all. Yechen thought about it, and summoned Hai Xinyan again, trying to slowly integrate Hai Xinyan into the Falling Heart Flame.

The Fallen Heart Flame itself is a cheat for cultivation and refinement, and if it can completely stimulate the potential energy in the body, then the result will obviously be different.

And the energy that erupted at this time, Yechen didn't dare to guarantee that it could be controlled, so he approached as slowly as possible, relying on the precise control of power. The Purple Pole Demon Pupil was opened, and the Xuantian Gong was also running at the same time. It is necessary to pay attention to the energy changes of the different fires themselves at any time, and also control the possible changes that may occur when the two different fires collide with each other at any time.

"Strange fire, different fire, what is your true source?"

Just by fusing the two different fires with each other, there is already an incredible power, and if the twenty-two different fires are gathered, then the energy that erupts after the successful fusion can simply defy the sky.

The energy is about to burst out, gradually expanding, and Yechen desperately tries his best to prevent the leakage of energy, control every cent of his fighting spirit, and appease the restlessness of the strange fire. You may not fully understand the performance of the fire itself, but through various experiments, you can slowly figure it out.

"Boom~~~"

The energy was too huge, and an ultra-high heat energy spread out in an instant, and Yechen immediately released his Dou Qi, mobilizing the energy in the surrounding air, and then the Dou Qi armor instantly covered the entire body, which escaped the danger of being attacked by the heat energy.

Sea Heart Inflammation is the mildest form of alien fire, and it can also have this effect after fusing with Fallen Heart Inflammation. And the falling heart is fierce and fierce, between them there is a rigid and a soft, a yin and a yang, yin and yang, yin and yang, and the refining effect can be excellent!

Inside the Dan furnace, the vibranium was already rapidly melting, and the puddle of black juice lingering around was slowly soaking into the vibranium. This is like mixing noodles before making jade dumplings, it must be even.
