Under the three-pattern pill, refining medicinal materials is relatively simple, and only the medicinal liquid in the medicinal materials needs to be roasted out.

When it comes to the four-pattern pill, it is the most terrifying stage of alchemy, and just the refining of medicinal materials will make many alchemists unbearable.

A four-star alchemist is also a watershed among alchemists, and only when he reaches a four-star alchemist will he be called a senior alchemist.

Chu Han controlled the Dan furnace of the Siding Dan Furnace alone, refining different medicinal materials respectively, so that this relatively boring night did not pass so slowly.

When the first rays of the morning sun shone on the earth, everyone realized that Chu Han had been refining for a night.

This night, Chu Han had taken the pill twice, and now among the fifth ring, there were only three mad spirit pills left.

On the square, many of the spectators who had left the day before rushed back, and when they saw Chu Han controlling the Siding Dan Furnace in his hand, a flash of shock flashed in their pupils.

Shout!

At this time, when the medicinal materials in the Fourth Ding Dan Furnace had been refined to only one-third of them, Chu Han's right hand moved again.

The Fifth Ding Dan Furnace has appeared!

Hiss......

This scene suddenly made the audience gasp, and a sense of suffocation permeated their hearts.

It's crazy!

Whether it was Cui Lao in the audience, or the heads of the three families, or the teachers of Triumph Academy, they were all speechless in surprise at this time.

Whether it is an alchemist or a non-alchemist, everyone clearly understands that every time they control one more Ding Dan furnace, the difficulty of alchemy increases exponentially!

Cracking sound......

Chu Han's little finger in his left hand came out little by little, and the Fifth Ding Dan Furnace was wrapped in thunder and lightning, and the terrifying temperature instantly rose.

Airplanes......

At this time, Chu Han's heart beat violently, and the dark golden blood rushed straight to his brain, which suddenly made Chu Han's head much clearer, and his thoughts on alchemy became clear.

This alchemy, for Chu Han, belongs to the dual experience of body and spirit, and it also made him understand one thing.

Only a strong physique can support the majestic spirit.

After Chu Han's body was transformed by the Dragon Emperor's essence blood, it revealed indescribable benefits in many places.

Whoa......

With a wave of Chu Han's right hand, the fifth batch of medicinal materials sank into the Dan furnace, and suddenly the heat rose, and the medicinal fragrance overflowed.

The Wuding Dan Furnace was located in the five directions of Chu Han's body, enveloping Chu Han in it.

After putting all the medicinal materials into the Dan furnace, Chu Han's right hand was completely liberated, and a crystal ring appeared on his finger, which was the dragon crystal jade ring that had not been used for a long time.

The next moment, the five fingers of Chu Han's right hand spread out, and five thunderbolts of lightning were held at the five fingers, intertwined with the electric light of his left hand, jointly maintaining the change of flames.

The Wuding Dan furnace has changed completely, and the temperature changes between each other are different, and Chu Han was able to maintain such a change, which made everyone in the audience look at each other in shock.

At this time, no audience felt that this was a boring thing anymore, tens of thousands of eyes were fixed on Chu Han's body, and each eye carried a touch of expectation, looking forward to what kind of surprise Chu Han could bring them!

As time passed, the spiritual power in Chu Han's body was gradually exhausted, and the thunder spiritual power stored in the dragon crystal jade ring frantically poured into Chu Han's meridians, maintaining the refining work.

Slowly, the sun hung high in the center, scorching the earth, and Chu Han still controlled the changes in the flames, without the slightest slackness.

The remnant sun was like blood, staining the clouds on the horizon red.

At this moment, Chu Han's eyes bloomed with brilliant lightning, and his hands changed continuously, removing the thunder and lightning on the Dan furnace, and the temperature of the Wuding Dan furnace plummeted in an instant.

Such a sudden change immediately attracted everyone's attention, and everyone realized that the step of refining medicinal materials was completed!

Everyone couldn't help but be secretly frightened, just refining medicinal materials lasted for a day and a night, what kind of ammunition was Chu Han refining?

On the high platform, Chu Han took a deep breath and slowly spit it out, trying to calm his mood.

The step of refining the medicinal herbs is complete, and now it's time to fuse the medicinal liquid!

This is the most important step in refining the four-pattern elixir!

Five kinds of potions containing majestic energy are about to be completely fused together!

Chu Han's wrist flipped, and three mad spirit pills appeared in his hand.

Now this time was the only time he could take the pill, but he only had the Crazy Spirit Pill left in his hand!

"Do your best!"

A look of determination flashed in Chu Han's eyes, and he immediately devoured the three mad spirit pills.

The fusion of the liquid medicine of the four-pattern pill is an extremely troublesome step, if there is no help from the power of space, you must keep absolute calm, and slowly fuse little by little, otherwise a little fusion will fail, and all the previous efforts will be wasted!

This situation was not suitable for taking the Madness Spirit Pill, but Chu Han had no other choice, and there was no better choice.

The Crazy Spirit Pill melted in his mouth, instantly causing the spiritual power on Chu Han's body to rise steadily, and his cultivation rose in a straight line.

The sixfold pinnacle of the Agile Realm!

The Sevenfold Early Stage of the Agility Realm!

Mid-Sevenfold Agility Realm!

Sevenfold Late Stage of the Spirit Realm!

The sevenfold pinnacle of the Agile Realm!

The Eightfold Beginning of the Agility Realm!

Chu Han's cultivation was finally frozen in the early stage of the eightfold spirit realm, and the instant fullness of spiritual power allowed him to grasp the fusion medicinal liquid a lot.

Chu Han carried the terrifying thunder and lightning in both hands, and directly rolled onto the Siding Dan furnace behind him, wrapped the medicinal liquid in it, and shot it out.

Boom! Boom! Boom!

Four streamers of light burst out of the four Ding Dan furnaces and poured into Chu Han's first Ding Dan furnace.

The five clusters of liquid medicine were located in the five corners of the Dan furnace, keeping a safe distance from each other as if they were strangers probing each other.

Whew!Whew!

Chu Han controlled the five clusters of medicinal liquid to rotate, and as the speed of rotation accelerated, these five clusters of medicinal liquid converged towards the center, blending with each other, constantly colliding with trembling energy.

"Melt it for me!"

Chu Han roared suddenly, like a dragon's groan, and the coercive aura compressed the entire Dan furnace, which suddenly caused the tumbling medicinal liquid to gradually merge, and the power of repulsion was much smaller.

On the square, there was silence, tens of thousands of eyes were staring at Chu Han, and everyone knew that Chu Han's alchemy had entered the most critical moment, and every move on the high platform tugged at their heartstrings.

Boom! Boom!

Just when Chu Han mixed the medicinal liquids with each other, a dark cloud appeared in the sky without warning, and the dark cloud just appeared directly above Chu Han's head.

Hiss......

In the dark clouds, thunder and lightning flashed from time to time, as if there were thunder and lightning silver snakes swimming in them, and the sound was extremely terrifying.
