Eliminating the distracting thoughts in his heart, Chen Han slowly gathered the true yuan in his body.

"Bang!"

A muffled sound rang out.

A large area of green flame suddenly emerged, frantically surrounding the furnace of creation. A large area of flames jumped up desperately, and the moment it appeared, it had already raised the temperature of the entire space to the highest. The original world of ice sculptures is also slowly melting.

"It's going to be even hotter!"

On the side, Emperor Yu hurriedly commanded.

"This is a quasi-seven-grade elixir, if the temperature is not enough, it is difficult to melt and refine the herbs!"

Nodding secretly.

Chen Han immediately increased the output of Yuan Force, and immediately that large area of flames rose up desperately.

Taking out the green lotus, Chen Han threw it into the green flames.

Rumble!

The flames jumped up, quickly enveloping the green lotus flower in it. In the air, there was a scorching sound of 'hissing'.

The green flame quickly condensed.

The green lotus flowers began to melt one by one......

"Okay!" Emperor Yu nodded, "Now, condense the flames." Calcination section by piece!"

Hear the words.

Chen Han immediately complied.

The green lotus flower was quickly calcined into a mass of green liquid in the flames, and the liquid slowly rolled in the flames, reflecting a faint luster.

The bewitching flames rolled more and more intensely.

And at the moment.

The temperature of the flame was still gradually rising, and when the temperature of the flame was maintained to a certain limit, a little yellow impurity suddenly appeared in the green liquid.

"Impurities?"

Chen Han raised the corners of his mouth.

Just like before, the impurities in it are removed.

"Boy, slow down, leave that impurity behind...... Emperor Yu hurriedly shouted.

"Uh......"

Although he didn't understand the meaning of Emperor Yu's words, Chen Han still nodded.

Immediately.

Separate a cloud of spiritual power and separate the yellow impurities from the package.

Looking at the yellow impurities that had been separated, Emperor Yu nodded with satisfaction and motioned for Chen Han to continue.

After the impurities were separated, small pale yellow impurities appeared one after another. And these impurities were all retained by the emperor without exception. It wasn't until there were no more impurities in the green liquid that the Emperor slowly spoke—"Okay, let's get rid of those green liquids, we don't need them anymore!"

What the?

Although Chen Han had already guessed Emperor Yu's thoughts, when he said it, Chen Han couldn't help but be a little surprised.

"You're not kidding, old man. You actually want me to keep this mess of impurities, and also throw away the essence of the greenest lotus?" Chen Han said in surprise.

"Hehe, that's right!" Emperor Yu couldn't help but nod and said, "This green lotus is the Sun Lotus. The lotus itself does not have much ability. However, it is able to absorb the purest abilities between heaven and earth...... If you don't believe me, what are those yellow impurities?"

Nodding.

Immediately, Chen Han separated a ball of spiritual power and sensed the yellow impurities towards it.

Because.

In the past, when he encountered this kind of impurity, Chen Han would remove it and rarely keep it, let alone bother to perceive it.

But.

When the spiritual power sensed and left, Chen Han couldn't help but be surprised.

Because...... In that mass of yellow impurities, there was a huge amount of energy. Moreover, this energy is still quite huge, and the energy contained in it is even comparable to the true yuan possessed by a Martial Emperor!

"Old man...... What's going on?" Chen Han couldn't help but say.

"The role of the sun-facing lotus flower is to absorb the power of the sun. This flower has a thousand-year lifespan...... A thousand years is enough time to generate a powerful energy. Emperor Yu paused and continued. "Okay, let's just place this impurity in the Dan furnace and start refining...... Because the Lotus Flower sometimes draws on some of the power of the Taiyin of the night, you need to mobilize that trace of the power of the Taiyin right now and refine it into an elixir!"

There is still the power of Taiyin?

Chen Han couldn't help but feel that one head was two big.

If it weren't for Emperor Yu's guidance here, I'm afraid he wouldn't know how to do alchemy.

He took a deep breath and did as the Emperor had instructed.

Gradually.

The clumps of yellow impurities had fused together again.

However.

Chen Han's spiritual power did not stop at all.

Saw.

In the yellow impurities, a trace of silver bright gas was slowly pulled out, and quickly gathered in the Dan furnace.

"The yin and the sun are the most important objects that release the energy of heaven and earth. However, although the power of the sun is strong, the energy is too violent. Even a strong person in the Martial Venerable realm could not withstand the elixir refined using the power of the sun. The power of Taiyin is different, although its energy is slightly weaker than the power of the sun, but the effect is endless. If you take the Taiyin Pill during the battle, even if you fight for a whole month, you won't feel the slightest bit tired!"

And Chen Han.

While listening to the emperor's explanation, he did it according to the gourd painting, although he was a little in a hurry, but there was no big mistake.

Occasionally, one or two steps are taken wrong.

Emperor Yu will act in time to save Chen Han.

Gradually.

In the furnace of creation, the two round pills were already gradually taking shape.

"Up!"

When the green flame was about to disappear, Chen Han's left hand slammed into a jade bottle on the table, and then put the two pills in the Dan furnace, one black and one white, into it.

"It's finally over. This white elixir is the elixir of the sun. The black elixir is the pill of Taiyin. With just these two pills, I will be able to save my corpse faction this time and retreat!" Although his body was a little tired, looking at the two pills, Chen Han couldn't help but raise the corners of his mouth. After resting for a while, and waiting for the true yuan in his body to recover again, Chen Han was ready to start refining the 'Phantom Thunder Pill'.

Originally, the temperature in the house, which had gradually dropped, was once again raised by the green flames that flashed out.

Take a deep breath.

Put the herbs that had been prepared one by one into the Dan furnace.

Hands on the Dan furnace, slowly refining.

And the Emperor.

It was quietly stepped aside, and he didn't plan to continue to help with the next 'Phantom Lei Dan'. Because, Emperor Yu understands that a young chick who only needs the protection of his elders will never be able to transform into a real eagle......
