Seeing that Lu Chengfeng was still hesitating, the female mage's first reaction was that Lu Chengfeng was disgusted with low pay. However, she quickly saw that Lu Chengfeng was not ignoring the value of this elixir, but was thinking about some other things. While curious about Lu Chengfeng's true thoughts, she hesitated for a moment, and then added a new chip.

"I guess you also know that the Demon Soul Demon Vine is about to advance, right? As far as I know, this is the time when the Demon Soul Demon Vine bears fruit. If you are willing to help, you will definitely have a share of the Demon Soul Demon Vine Fruit you get in the end. ”

This is a new condition added by the female mage.

The fruit of the Demon Soul Demon Vine is the essence of this strange demonic beast, and it is the most valuable part. Probably worried that Lu Chengfeng would be suspicious of her words, the mage also swore in the honor of the Liu family that he would definitely fulfill his promise.

Lu Chengfeng stared at her eyes for a while, and this sexy female mage also looked at him calmly. After stopping for a few seconds, Lu Chengfeng finally nodded and said, "Okay, I'll take this job!"

He decided to trust the woman, and his instincts told her that helping out would give him something in return.

"Feel free to sit and wait for me to advance. ”

Lu Chengfeng invited the girl into his room, and then sat alone in the next quiet room. After calming down for a while, he swallowed this Qinglian Peiyuan Pill with clear water, absorbing the medicinal effect of the pill with all his might.

This pill from the Liu family was at least from the hands of a senior pharmacist, and the medicinal effect was very strong. As soon as he entered his body, warm pure energy quickly poured out. At first, it was a little like a stream, but in an instant it became a big tide. The powerful medicinal effect made Lu Chengfeng's body shake violently. He worked hard to maintain his calmness, channeling the Dou Qi in his body to attract medicinal power, and finally began to refine frantically.

In the small quiet room, the air that should have been windless quietly rippled at this moment.

Before being reborn, as the prince of the empire, Lu Chengfeng began to receive the tempering of precious herbs since he was a child, and his physical foundation was excellent. When I took Qinglian Pei Yuan Dan for the first time, there were almost no problems, and I successfully refined all the medicinal powers. However, after being reborn, the foundation of this body is obviously much worse, and the tenacity of the meridians is incomparable. Under the double pressure of the huge medicinal power and the full operation of the fighting qi, the meridians of the whole body continued to send bursts of tearing pain.

Fortunately, Lu Chengfeng is also very experienced in this area.

He carefully guided the medicinal power and always controlled the refining rhythm. Although the meridians were in pain all the time, the body was not damaged too much. On the contrary, with the continuous refining, there is constantly energy being assimilated into a part of the Dou Qi. With the addition of these continuous helps, the scale of the Heavenly Wind Dou Qi in Lu Chengfeng's body is constantly expanding at a degree that is visible to the naked eye.

However, the pure medicinal power of Qinglian Pei Yuan Dan seemed to be endless, and it was still in full play.

The entire refining process lasted almost ten minutes. When the refining medicinal power and Dou Qi were almost saturated, Lu Chengfeng's Dou Qi was also a few points faster, and it could be said that it had reached the peak of what the third order could bear. Realizing that the opportunity for a breakthrough was coming, Lu Chengfeng put out the unique guidance technique of the Tianfeng Lu family, using his handprints to cooperate with the control of the spirit, so that the fighting qi in his body was like a wild horse, and suddenly burst out.

In the quiet room, there seemed to be a dull clicker sound.

In the next moment, Lu Chengfeng's 72 Heavenly Wind Fighting Qi was devastated, breaking the original confinement.

After completing the breakthrough, both the total amount of Dou Qi and the running speed were nearly doubled, directly allowing Lu Chengfeng to step into the fourth order. After the cyclone in his body stabilized, it was also twice as large as before, and the color of the fighting qi had almost turned milky white.

After looking inwardly at his body, Lu Chengfeng nodded with satisfaction.

After relying on the new Heavenly Wind Dou Qi to break through the fourth order, Lu Chengfeng's strength has made great progress compared to before. The medicinal effect of Qinglian Pei Yuan Dan has also improved the previously slightly weak physique. Feeling the surging fighting energy in his body, Lu Chengfeng was finally able to release the true fourth-order lightsaber technique without the help of ogre potions.

After opening his closed eyes, Lu Chengfeng pulled out his lightsaber, simply threw a few sword flowers in the quiet room, and changed the starting style of his sword skills one after another, and finally let out a sigh.

This is the power of a fourth-order swordsman!

Stepping into the fourth order earlier than expected, Lu Chengfeng no longer had to worry about the threat of the Blood Knife Squad. Moreover, if this trip goes well, it can also make the Liu family in the southeast province owe themselves another favor. It is undoubtedly very beneficial to its future development. Once he was allowed to successfully step into the fifth order and get the Infinite Frost Technique in the Heavenly Wind Empire's secret vault, Lu Chengfeng would no longer have anything to worry about.

After thinking about it secretly, Lu Chengfeng tidied up a little, and then opened the door of the quiet room with a confident smile.

"Congratulations!" The girl glanced at Lu Chengfeng, knew the result, and said a little impatiently: "Let's go!"

"Don't worry. Lu Chengfeng smiled and motioned her to be calm: "I'm going to find someone, if I deal with the Demon Soul Demon Vine, he may have some good things there." ”

After all, the Demon Soul Demon Vine was a special demonic beast at the peak of the fifth order, and even if Lu Chengfeng successfully advanced to the rank, he still didn't dare to underestimate it. Therefore, he thought of going to Xu Yinjie. No matter how powerful the Demon Soul Demon Vine is, before stepping into the sixth order, it is more plant-oriented after all. And as long as it is a plant, it will be afraid of fire. Xu Yinjie is an intermediate alchemist, and if he gets some flame-bursting potions and the like from him, it will definitely be very effective.

In fact, if it weren't for the Demon Soul Demon Vine's innate restraint mage, it would be the best choice to let this powerful fifth-order fire technique around him deal with it. It's a pity that the target is so special, and this sister obviously cares about her sister very much, for fear that Lu Chengfeng will hurt her by mistake. As a result, Lu Chengfeng could only find a way to increase his chances of winning.

"Welcome, welcome!"

Seeing that Lu Chengfeng took the initiative to come to the door with a person, Xu Yinjie couldn't help but take a look, but he still enthusiastically let Lu Chengfeng in. When he learned of Lu Chengfeng's intention, he didn't say a word, and found a whole bundle of explosive potions from the magic closet.

This explosive inflammatory potion, after being mixed and shaken out, will produce a violent explosion and continuous high-temperature burning once the bottle shatters and comes into contact with the air. For the Demon Soul Demon Vine, it can greatly suppress its combat power.

Lu Chengfeng looked at the bundle of potions and asked with satisfaction, "How much?"

Xu Yinjie's eyes blinked, and he said a little unhappily: "If you want to see you like this again, I won't welcome you next time." ”

Lu Chengfeng smiled and pointed to the mage beside him who had put on his cloak again: "The rich man is here, I'm here to pull business for you." ”

"She checks out?" Xu Yinjie glared, there was a big meaning of why you didn't say it earlier, and immediately changed his words in a hurry: "A bottle of explosive potion is two thousand gold coins, and a bundle of six bottles of potion will benefit 12,000 gold!"

Although the explosive potion is easy to use, the lethality to humans is not as great as imagined, so the real price is definitely not two thousand bottles. Xu Yinjie obviously also noticed the extraordinaryness of this fire mage, so he at least raised the price by three percent.

As a family of mages that have been inherited for hundreds of years, it is certainly impossible for the genius fire mage of the Liu family not to know the true price of the flame popping potion. However, even the Qinglian Pei Yuan Dan was taken out, and she didn't bargain for this bundle of medicines, and simply took out the crystal card and drew 12,000 gold.

"What a rich man!"

Xu Yinjie smacked his lips, and saw that Lu Chengfeng had put the potion into his space bag with peace of mind, and suddenly found that he still had the potential to be a little white face. While being happy for his friend, Xu Yinjie couldn't help but be happy. The materials for the preparation of the explosive potion are not expensive, and if he continues to do this business, he can at least earn seven or eight thousand gold coins.

In the evening, you can consider getting some wine and food.

"Alright, now it's time to go. ”

With the potion in hand, Lu Chengfeng did not delay any longer, and went out of the city with the beautiful fire mage beside him. By the way, Lu Chengfeng and this woman have met twice, and they have also talked about a business, but they still don't even know what the other party calls her, only know that her surname is Liu.

"I thought you could keep your breath and don't ask......"

Seeing that Lu Chengfeng finally asked his name, the fire mage muttered vaguely and replied, "My name is Liu Yuhan, and my sister's name is Liu Yubing." Well, she's only half a day older than me. ”

Are they twins anyway?

Before Liu Yuhan said it, Lu Chengfeng already had a little hunch. Now that it has been confirmed, I can't help but envy the people of the Liu family. Such a young pair of sisters are actually genius elementalists. is only in his twenties, and he is already a fourth-order and a fifth-order, and there are absolute successors!

Because both sides have their own scruples, when Lu Chengfeng and Liu Yuhan went out together, they went out in a caravan. After leaving the city, the two of them entered the Endless Forest as fast as they could. So even if someone wants to do something, it's hard to keep up.

Worried about Liu Yuhan's sister, the two avoided most of the battles along the way and rushed to the Tianquan Mountain Range. In just over a day, the two arrived at their destination. After a short rest, Lu Chengfeng and Liu Yuhan finally confirmed the plan, and then went up the mountain side by side.

If it was against other magical beasts, Liu Yuhan might use a scroll that could cover his breath to help the two launch a surprise attack. However, the spiritual perception of the Demon Soul Demon Vine was too strong, and the ordinary hidden scroll was not effective at all. Therefore, the two did not use any special means, but went up the mountain in a timely manner.

However, perhaps sensing the familiar enemy coming again, the Demon Soul Demon Vine took the initiative to attack this time. Soon after the two of them stepped into the snow line, the controlled fourth-order ice method stopped in front of the two of them.
