Mr. Rao is Yin's Qi cultivation kung fu has been perfected, and after hearing what Lin Fei said, he couldn't help but show a look of surprise.

However, with Mr. Yin's vision and knowledge, when his mind moved, he quickly understood what Lin Fei's purpose was, so he nodded slightly and said, "With your current strength, it is just a ******** retreat and penance, and it really won't help you much." However, you should understand the reason for making a big move, you are now on the cusp, if the news of going out leaks, do you know how much trouble it will cause?"

Lin Fei nodded again and again: "Thank you for your concern, this is something that the students know in their hearts." Therefore, this time the students plan to retreat for more than ten days, and if this problem can be solved, it is not too late to go out for trials at that time. ”

Mr. Silver was a little puzzled and asked, "How are you going to solve it?"

Lin Fei said: "The student has a little idea, but if it doesn't work out, I have to ask your old Professor Hehai to help check it." When the students finish this retreat, please invite your veteran Professor Hai to come over, and see if it will be effective or not!"

Lin Fei's demonic talent has always been unable to be regarded as common sense, this Mr. Yin has long known, and he is also very curious in his heart, he really wants to see how incredible things Lin Fei can do, so he nodded and agreed: "Okay, this time you retreat first." When you come out, if you can't satisfy the old man and Xiaohai, don't think about leaving the academy, it's better to stay in the academy honestly and wait until you have accumulated enough!"

Lin Fei nodded with a smile and said, "Okay, I hope the student can satisfy you this time!"

After getting Mr. Yin's approval, Lin Fei immediately stepped into the thunder pool and was soon teleported into the Wind Thunder Gate.

This time, the purpose of Lin Fei's retreat was very clear, that is, to improve the ******** and the Eighteen Swords of Blood Evil, so he directly chose a suitable place for the retreat refining weapon, and began to transform the ******** as soon as possible.

I have to say that ******** can indeed be regarded as the genius stroke of the ugly master, once such a special magic weapon comes out, it will even attract jealousy, otherwise there will be no such exaggerated side effects.

Lin Fei was able to improve his ******** in his previous life, in addition to being the number one refining master in the Kunlun Realm, he also had a unique advantage that only he possessed, that is, he controlled the Origin Fire!

Why are the side effects so great? It is because although the ugly master is clever in refining weapons, it is not enough to refine such an artifact, even if he refines the ******** under the burst of inspiration, but when it is finally refined and finalized, there will inevitably be some mistakes, making it impossible for the ******** to refine it to a perfect state.

If you want to remedy this, it is not something that can be done casually, even if Lin Fei cultivates the true fire to the highest level, it is still a little bit hot when it is used to refine ********. However, the Origin Flame is different, as long as this Origin Flame power that exists at the beginning of heaven and earth is used, what else can't be done?

In particular, the Origin Fire Red Lotus Fire obtained by Lin Fei in his previous life has the wonderful use of extinguishing and rebirth, and it can be said that it is the most suitable peerless divine fire for refining weapons and alchemy, so it can be said to be extremely suitable to improve the ******** and complete the last step of purification.

As for the current life, although Lin Fei has not been able to get his hands on the Red Lotus Fire again, the Green Flame Fire he obtained, in terms of flame power alone, is still above the Red Lotus Fire, as long as he can use the little power of the Green Flame Fire to purify ********.

In the final analysis, although ******** can be regarded as a top-notch disguise magic weapon, even the Yuanying powerhouse can hide it, but after all, it is refined by the day after tomorrow, and it is too far from the innate origin fire. Therefore, whether it is a red lotus fire or a green flame fire, it only needs to use a little power to successfully improve the ********!

Being within the Wind and Thunder Gate, Lin Fei could finally use the power of the Qingyanhuo with confidence and boldness, even if the Qingyanhuo was not refined by him, and it was not under his control, but borrowing a little Qingyanhuo power was enough to achieve his goal of refining.

I saw that after Lin Fei sacrificed his ******** and let it levitate in mid-air, he first used the Golden Crow Fire to wrap the entire ********, and then borrowed a trace of the power of the Green Fire to integrate a faint cyan fire into the Golden Crow Fire!

With the help of the Blue Flame Flame, the power of the Golden Crow Fire was not only multiplied? Now it can be seen with the naked eye, and under the scorching ******** flames, it will soon become brilliant, and the water ripples on the surface will appear even more lifelike!

The transformation of ******** is a slow work and meticulous work of water milling, which does not allow for a little impatience, as long as the ******** is purified little by little, its side effects will eventually be eliminated in one fell swoop.

After nearly ten days, Lin Fei suddenly felt something, and he put away the Golden Crow Fire, and the trace of green flame that had originally seeped out naturally shrank back into his sea of consciousness.

At this time, when I looked at ********, it seemed that I had lost all my spirituality, and there was no longer that layer of water ripples on the surface, as if it had become the most ordinary bronze mask. However, Lin Fei was able to establish a mental connection with ********, and it was easy to confirm that the ******** had been transformed and there were no more side effects.

Being able to successfully improve the ******** can be regarded as completing Lin Fei's main purpose of this retreat, and as long as the side effects of the Eighteen Swords of Blood Demon are eliminated, it can be regarded as a complete success.

Solving the problem of the Eighteen Swords of Blood Demon is much simpler than improving ********, at least there is no need to use the Origin Fire, just the Golden Crow Fire is needed to achieve the goal.

The side effects are caused by the lack of ability of the ugly master to purify it sufficiently. The side effects of the Eighteen Swords of the Blood Demon are completely opposite, because the ugly master used too much force and was too devoted, which led to a set of flying swords at the end of the line, and he fell into a problem of sucking the essence blood of the sword master.

What Lin Fei has to do now is to refine the Eighteen Swords of Blood Evil, on the premise of retaining their Blood Evil Qi without weakening, so that it will no longer suck essence blood, and only ordinary blood is needed to completely stimulate the Blood Demon Qi.

The transformed Eighteen Swords of Blood Demon will be more suitable for the way of killing, and with the sword array supernatural power, it will be even more powerful, which is the most suitable set of offensive magic weapons for Lin Fei at this stage. (To be continued.) )
