PS: (Sorry, there was a power outage here today, but fortunately, it was not a high-voltage power outage, although it was slow for dozens of minutes, but fortunately, it was still rushed out! The second more was sent! By the way, I asked for a collection, recommendation, subscription! Thirteen is grateful!!)

Han Chen raised his head and looked at the sky, he didn't know when the road began, the originally endless clear sky, but at this time, it was already covered with dark clouds, and the thick black clouds gave people a strong depression, and their hearts were heavy, making people feel breathless.

"Boom"

From time to time, there would be bursts of deafening thunder from the depths of the dark clouds, and the gloomy weather made Han Chen couldn't help frowning, although it was a little strange that it was still a cloudless good weather just now, how could it be cloudy in the blink of an eye.

But looking indifferent, his mind focused on refining Guiguzi. Han Chen didn't think about this, he quickly gathered his mind and observed carefully.

In the "booming" sky, roaring thunder came from time to time, and the dark clouds were getting thicker and thicker, and it seemed that the next moment the Tianhe River would collapse and it would rain heavily.

As the black clouds became thicker and thicker, the suppressed momentum made the four-star demonic beasts in this mountain range also feel irritable, and the roars of beasts full of anger sounded from all directions and reached Han Chen's ears.

"What's wrong with these guys?" Hearing the roars around him, Han Chen couldn't help but mutter.

At this time, Guiguzi, who had already completed the 'smelting' step, looked up at the thick dark clouds in the sky that seemed to be like ink that could not be dissolved, and a smile appeared in his eyes.

"'Carving Array' is the fourth step of refining. It is also the most important step. It is necessary to use soul power to supplement the seal knot, and the formation one by one is entered into the refining embryo, this step is not only a test of the mastery of the formation and the connection between each other, but also a test of the proficiency of the control of the seal knot. It's very important!"

"You have to remember!!"

At this time, Guiguzi had already withdrawn his gaze, and his right hand of the false samadhi true fire was slowly withdrawn, and he joined the left hand, and his fingers were bent left and right, and he was connected up and down. Begin to tie up the knots. At the same time, he opened his mouth and said.

"Hmm!" Han Chen also knew in his heart that this was the most important time, and his eyes were even more staring at the movements in Guiguzi's hand without blinking, and he nodded in response.

I saw that with the change of the fingers between Guiguzi's hands. One by one, mysterious knots were knotted. And with the completion of the stamps one by one. Black light flew up quickly from the knots formed by Guiguzi's hands, and landed on the inky sword embryo floating in the true fire of Samadhi.

Guiguzi kept moving, and the movements between his hands became faster and faster. Streams of black light kept flying from the knots formed between the hands.

Han Chen's eyes stared at him tightly, although he struggled to see the movements of Guiguzi's seal, but as time passed, Han Chen's eyes gradually had a sour and stinging feeling, and his eyes gradually couldn't keep up with Guiguzi's movements.

I only felt that in front of me, it seemed that dozens of hands were moving together, and I couldn't see the changes in Guiguzi's hands clearly.

After a while, Han Chen finally couldn't hold on, and couldn't help but raise his hand to rub his dry and sore eyes.

At this moment, Guiguzi's voice happened to sound and came into Han Chen's ears: "This seal is called 'Array Seal', which is similar to the 'Dan Seal' of alchemy. With the 'array seal' as the guide, the formation is imprinted in the sword embryo. And the formations are the ones you usually learn in the Bagua diagram!"

"Uh, how many 'array marks' do you usually have to form before you can successfully imprint a formation?" Han Chen was slightly stunned, and then asked.

"An entry-level formation generally only needs nine array seals to be successfully imprinted, just like the thousand heavy formations you have already learned, it is nine array seals, and with the depth of the formation realm, the more array seals need to be formed. ”

"Some powerful formations, even if they are hundreds of thousands of formation seals, may not be able to completely imprint successfully!" Guiguzi said.

"Is that the more imprinted formations there are, the better the quality of the embryo will be?" Hearing this, Han Chen nodded as if he didn't understand, and then asked again.

It can be seen from Guiguzi's calm and calm expression that it is obvious that the step of 'carving array' does not have any pressure on him, and he smiled slightly: "According to the truth, it can be understood in this way! But the key to how many formations can be imprinted lies in the quality of the embryo!"

Hearing this, Han Chen's eyes suddenly lit up, and his eyes stared at the ink-colored sword embryo floating in the air and wrapped in samadhi true fire.

He knew that after such a short period of effort, Guiguzi's hands had never stopped, but the movements of the seal were getting faster and faster, and the movements of his fingers had already brought out the afterimage.

"At least more than 400 seals have been concluded!"

According to the standard of one formation for the lowest nine formations, Guiguzi has at least imprinted more than forty formations

"Boom"

"Roar!!"

"Roar!!"

"Huh!!"

As time passed, Guiguzi's hands moved faster and faster, and more than two thousand seals had been formed, but he had no intention of stopping.

The thunder in the sky became more and more rapid, and the roars of beasts in all directions of the mountains became more and more frequent, one after another.

So many four-star demonic beasts roared in unison, and the anger and powerful aura in their voices were condensed together, like a monstrous fierce flame, which actually squeezed out some of the dark clouds in the sky.

But these did not affect Han Chen and Guiguzi.

In the blink of an eye, the time of two teas has passed, and at this time, Guiguzi's hands are constantly changing, and more than 10,000 knots have been formed, and the continuous black halo has already formed a black line in the sword embryo and Guiguzi's hands, like a bridge.

Han Chen, who was on the side, was excited, and at the same time, he was dazzled by Guiguzi's rapidly changing movements.

Finally, when Guiguzi's hands completed a seal knot again, the movement between his hands suddenly stopped.

A black halo flew out of the seal and fell into the sword embryo, and the sword embryo floating in the samadhi true fire trembled slightly.

Seeing that Guiguzi's movements stopped, Han Chen felt a little regretful in his heart, but at the same time, he also breathed a sigh of relief.

After several hours of refining, the sword embryo became more pure, and a faint black halo enveloped it, making the inky black color more intense and rich.

At this time, as Guiguzi's movements stopped, Han Chen knew that the step of 'carving the array' was finally completed!

Separated his hands and dispersed the seal, Guiguzi exhaled lightly, after such a long time of continuous sealing, branding formation, Guiguzi also felt a little tired.

I looked up at the dark clouds that had accumulated in the sky, which were already as black as ink. From time to time, you can also see the silver snake-like thunder flashing in the dark clouds, and then bursts of thunder sounded in the ears.

"Almost!" The words with a slight expectation and relaxation slowly spat out from Guiguzi's mouth.

Hearing this, a trace of doubt flashed in Han Chen's eyes, and he looked up at the black clouds that were surging like ocean waves. Then he glanced at the inky black sword embryo.

It seems that this black cloud appeared because of this sword embryo!

At this time, Guiguzi's hands formed a knot again, and at the same time, his eyes condensed, and he gently spit out a word.

"Quench!"

When the words fell, I saw the Samadhi True Fire floating in the air suddenly surging rapidly like ocean waves, and the temperature soared sharply, reaching a terrifying level in an instant.

A faint ripple in the air, centered on the Samadhi True Fire, spread rapidly in all directions.

Seeing this ripple, Guiguzi frowned slightly, and with a wave of his left hand, the ripples in the air instantly dissipated. Immediately, his mind converged again.

Seeing this scene, Han Chen's pupils suddenly shrank.

With Guiguzi's current strong soul power, it will be uncontrollable, resulting in spatial ripples, which shows what a terrifying level the temperature in the Samadhi True Fire has reached at this time.

Turning his gaze, he saw that in the Samadhi True Fire at this time, the demonic blood color suddenly became extremely rich, like a blood cocoon, completely enveloping the sword embryo, and the rich blood color completely blocked Han Chen's sight, and he couldn't see what was inside at all.

The fifth and last step of the refining process.

'Quenching' begins!

"Boom!!" As time passed, the black clouds in the sky became thicker and heavier, and the oppressive aura became heavier and heavier, as if the sky was about to fall, which made people irritated.

At this time, the four-star demonic beasts in the mountain range seemed to know that the power of the Dao Heavenly Might was irresistible, and they had all died down, and there was not a trace of the beast's roar.

For a moment, between heaven and earth, it seemed that all sounds had disappeared, only the continuous roar and thunder in the sky. (To be continued......)
