For the next three days, Chu Chen practiced in retreat in the Great One Dart Bureau, waiting for the Fengdu Business Alliance to send over the spiritual materials and elixirs he needed.

In the past three days, Xia Qiongying has been as gentle as water, always by Chu Chen's side, allowing him to enjoy all the gentleness.

Except for not correcting her on the spot, the two are already extremely intimate, as if they were a young couple.

Three days later, Elder Yang sent someone to send over all the things he needed, and the number was fully doubled, which made Chu Chen have a better understanding of the background of the Fengdu Business Alliance.

On the fourth day, Chu Chen began his retreat.

"The first thing is to refine the Zhan Dan!" Inside the house, Chu Chen sat cross-legged, enclosing the space of knowing the sea to prevent the little old man from knowing his secret, and then took out the Thunder Flower and other materials found in the Thunder Mansion and began refining the Zhan Dan.

The so-called war pill is a kind of elixir used by alchemists in ancient times for fighting, after all, although the alchemist has a respected status, but his own combat power is not strong, and he has refined this kind of war pill with powerful predecessors, which greatly enhances the alchemist's ability to save his life.

The elixir is not only to improve cultivation, detoxify and cure diseases, but also to kill people!

"It's not difficult to refine the Battle Pill, the most difficult thing is the last step, to melt the martial arts into the Dan!" Chu Chen's heart flowed through the record in the Martial God Treasure Vault, and he began to refine it.

The Xuantian Ice Flame flew out in an instant, transforming into a small flame tripod, and each piece of spiritual material was carefully thrown into the fire tripod by Chu Chen, but none of them were medicinal materials.

Zhan Dan is more like an alternative magic weapon, rather than an elixir, and what is needed for refining is spiritual materials, not elixirs.

"Melt!" Chu Chen scolded, and the materials in the fire tripod slowly melted into liquid under the high temperature of the Xuantian Ice Flame, and then began to fuse and condense.

"Refine!" The next moment, Chu Chen began to manipulate the dual power of ice and fire of the Xuantian Ice Flame, refining the essence of these spiritual materials, the liquid in the fire tripod slowly shrank, and the essence was refined.

Time passed slowly, and the essence of the spiritual material slowly condensed into a circle, circulating in the fire ding.

Suddenly, the round liquid began to tremble, as if it might collapse at any time, Chu Chen's eyes suddenly shrank when he saw this.

"Go!"

The thunder petals that he had held in his hand for a long time were shot out by him with a flick of his fingers, impartially, just on top of the circular liquid, the slightest ray of thunder flashed, wandering around the circular liquid, the tremor slowly disappeared, and finally settled down completely.

Finally, the liquid slowly condensed, and gradually became an elixir the size of a dragon's eye, and the whole body was shining with thunder, which seemed to contain huge energy.

Zhan Dan, Cheng!

But the last step was not yet completed, Chu Chen carefully put away the Xuantian Ice Flame, took this battle pill in his hand, and slowly condensed his mind, immersed in the internal space of the pill.

"Whoosh!"

Suddenly, Chu Chen's mind all entered the inside of Zhan Dan, this was a pitch-black world, Chu Chen's figure suddenly condensed, in front of him, a mirror made of petals emitted a faint blue light, completely reflecting his figure, which looked a little weird.

Chu Chen carefully observed the Thunder Petal Mirror in front of him, and suddenly his eyes froze, and his right palm instantly slapped out.

"Aang!"

The dragon groaned, but there was no sound at all, and the dragon-shaped phantom reappeared, surrounding the giant palm of true qi that appeared out of thin air, with the violent and raging thunder attribute energy, and shot towards the mirror in front of it!

"Bang!" Kang Long slapped on the mirror with regret, causing layers of ripples, bursts of thunder flashing, and after a long time, it calmed down, and the mirror of the petals was not damaged at all.

"It's finally done!" Seeing this, Chu Chen, who had been transformed by his divine sense, smiled faintly and slowly dissipated in the internal space of Zhan Dan.

Inside the room, Chu Chen's eyes suddenly opened, a smile flashed from the corner of his mouth, and he carefully looked at the battle pill in front of him, which had been completely refined, and let out a long sigh of relief.

The so-called war pill can be fused with martial arts in the pill, and a martial art can be sealed in the war pill, and when used, it can be used directly without consuming a trace of true qi.

If it was just like this, it would be similar to the magic weapon in Lan Ao's hand in Qingyulou, and it would not be worth Chu Chen's attention so much, and he would use it as one of his hole cards.

The biggest role of Zhan Dan is that in addition to sealing a martial art, it can also increase the power of martial arts by one level!

This is the horror of Zhan Dan!

"Kang Long has regrets and seals it in this battle pill, when it is used, the power can be raised by another level, if this war pill can be refined in batches, I am simply a mobile battery!" Chu Chen looked at this thunder attribute battle pill happily and carefully put it away.

"It's a pity that there is only one Thunder Flower, and this time I can only refine a maximum of seven Battle Pills, even so, my combat power can definitely increase by a few more!"

Time was limited, Chu Chen breathed a little, released the Xuantian Ice Flame again, and began to refine the next Battle Pill.

Time passed slowly, and the seven war pills were completely refined by Chu Chen, refining the war pill is mainly because the materials are difficult to find, and the refining method is not difficult, and its power mainly depends on the martial arts sealed in it!

Therefore, Chu Chen's success rate this time was ten percent, and all of them were received by him in the mustard seed bag.

After the pranayama was finished again, Chu Chen took out the Thunder Stone found next to the Thunder Flower, and his thoughts flowed in his mind, and then he controlled the Xuantian Ice Flame again and began to refine it.

Time passed slowly, and before he knew it, Chu Chen had been in retreat for seven days.

At this time, it was not far from the day of the assessment of the Lan Sword Sect, and there was still a long way to go to the Imperial City of the Wind Capital, and Chu Chen needed to set off as soon as possible.

"Whew!" Inside the house, Chu Chen put away the Xuantian Ice Flame, slowly breathed a sigh of relief, and looked at the various items in the mustard seed bag with a relieved face, these were his achievements in the past few days.

In addition to the seven battle pills, he also refined six sets of seventy-two Ice Spirit Divine Needles, and the Reverse Water Cold Sword was also re-refined with the Xuantian Ice Flame, basically recovering his spirituality, but the Burning Flame Knife had been broken, and with his refining level at the moment, he couldn't reforge it.

In addition, it is those things that are refined from thunder stones, and of course, it is indispensable, and some pills are also refined.

"With these pills, the strength of the big one dart game will definitely be greatly improved, and with the care of the Fengdu Business Alliance, I can also be a little relieved to leave this time. Chu Chen's thoughts crossed in his heart and he slowly got up.

It's time to leave.

Pushing open the door of the house, at a glance I saw Xia Qiongying practicing swords outside the courtyard who was practicing swords at the door, she was careful not to make a sound, thinking that it was to not disturb Chu Chen's retreat, and that appearance made Chu Chen's heart warm.

"Childe!" Hearing the movement, Xia Qiongying stopped practicing her sword and happily rushed to Chu Chen.

Her Cihang Sword Code has just stepped into the first level and is in the entry stage, but the power has already been shown, and Chu Chen believes that as long as she cultivates for a while longer, there will be no more opponents in the Qi Refining Territory.

"Xia Xia, this is the elixir I refined for you, you can give it to the second master. After confirming the relationship, Chu Chen's title became intimate, "The two Xuanling Pills, as well as some Xuanyuan Pills and Xuanqi Pills, are all high-quality pills that can help break through the realm, and you can assign them to your disciples as appropriate." ”

Chu Chen didn't refine many pills this time, after all, the time was limited, but it was still possible to let the big one dart game have more martial artists from the Qi Refining Realm, plus Xia Zhenxi, who had the possibility of breaking through to the Alchemy Realm, at least in the vicinity of Lei Ling City, they could completely deal with any situation.

"Okay!" Xia Qiongying took a few bottles of elixir, but her eyes were a little gloomy, "Childe, is this going to leave?"

Chu Chen was also a little reluctant, but he still said ruthlessly, "Yes, the assessment of the Lan Sword Sect is about to start, I must rush to the Fengdu Imperial City as soon as possible, I will go and say hello to the second master and them, and leave!"

"En, I'll send my son!" Xia Qiongying's eyes faintly flickered with tears, but he didn't hold back, he knew that Chu Chen's world was in the entire Nanyun Domain, and even, the Tianxia Domain!

There, is the place where Chu Chen gallops vertically and horizontally!

"Hehe, cultivate hard, we'll see each other soon!" Chu Chen smiled, gently picked up Xia Qiongying's pretty face, and kissed it lightly in the other party's gentle gaze, "This sword against the water and cold, you keep it for self-defense!"

As he spoke, he couldn't help but say that he handed over the Reverse Water Cold Sword to Xia Qiongying.

"Well, it will be!" The girl's gaze was extremely firm, and she vaguely seemed to return to the time when the two met for the first time, at that time, Chu Chen was also moved by these eyes, and took a strong move to save them.

Fate, sometimes that's just the magic.

Xia Zhenxi took everyone in the big dart game to greet Chu Chen at the door, and Yang Lao was also among them, which made Chu Chen a little surprised.

"Hehe, Master Chu, Mr. Ye had an explanation when he left, and when you arrive at the Imperial City of Fengdu, please send this letter to the Zhenguo General's Mansion. Elder Yang looked at Chu Chen and said with a smile.

"Okay!" Such a trivial matter, Chu Chen naturally would not shirk it, but as a result, the letter was put away with his hand and looked at the big dart board on the side.

"You don't have to send it anymore!" After a pause, he turned to Xia Zhenxi and said solemnly, "Second master, I will leave Xia Xia's safety to you, if something happens to her, I will ask you!"

The voice was clear, mixed with a touch of majesty, Xia Zhenxi nodded solemnly.

"Okay, I'm leaving!" Chu Chen smiled at Xia Qiongying, and Ling Bo's micro-step body unfolded, disappearing in an instant.

"Uncle, have a good trip!!"

Suddenly, there was a loud roar from behind him, which shocked Chu Chen's true anger, he almost didn't fall, and he was not angry enough to start his body again, and suddenly his heart moved, and his body quickly flashed back to the door of the dart game.

"Childe!" Xia Qiongying asked with concern when she saw him go and returned.

"Hehe, Xia Xia, I think the name of our dart game needs to be changed!" Chu Chen smiled slightly, and in the incomprehensible gaze of everyone, he took the Reverse Water Cold Sword from Xia Qiongying's hand, and in a flash, several sword lights flashed.

On the plaque in front of the dart game, the four big characters of "Big One Dart Board" originally engraved have quietly changed.

"The world's dart game!"

Everyone was shocked, and they actually felt a residual sword aura in these extra strokes, exuding a sharp aura that cut everything, and a sense of ambition and pride that vowed to rise to the sky!

At the same time, Chu Chen's figure still disappeared, leaving behind a loud laugh.

"The world's dart game, the world's darts!"

Everyone looked at each other, and they were all impressed by the pride of the young man, Xia Qiongying became more and more determined in her heart, looking straight at Chu Chen's back as she walked away, at this moment, she understood Chu Chen's heart.

The world is far from the end!
