In the past, Lin Fenghan didn't care about the refining methods of the eighteen magic weapons recorded in the "Xuanyuan Refining Records", but now that he recalled carefully, Lin Fenghan suddenly found that these eighteen magic weapons were all extraordinary, and each of them had unique value and magical powers.

And today, when Mu Xitong mentioned Xuanyuan Zhenren's past, Lin Fenghan suddenly woke up, with Xuanyuan Zhenren's refining achievements back then, even the Nine Demon Venerable Zhao Lie admired it incomparably, so how could the magic weapon he designed be as simple as it seems?

Lin Fenghan was suddenly silent, and his mind sank into the "Xuanyuan Refinery Record".

And this research was not tight, Lin Fenghan's face changed dramatically in an instant, because with the deepening of the research, these seemingly simple magic weapon refining actually contained infinite mysteries, including the Chongshan Thick Earth Armor that he refined according to the record in the "Xuanyuan Refining Record", which was actually wrong.

Lin Fenghan couldn't help but smile bitterly and muttered, "Careless, careless!"

Mu Xitong looked at Lin Fenghan's face was cloudy, and did not make any disturbances, and heard that Lin Fenghan suddenly laughed at himself, and immediately held Lin Fenghan's big hand with his small hand, and said: "Brother Han, although I don't know what you are thinking and what happened, I always believe in Brother Han!"

Lin Fenghan's expression perked up, looking at Mu Xitong's worried face, he couldn't help but feel a little in a trance, as if there was another cold shadow.

"Brother Han?" Mu Xitong stretched out his hand and waved in front of Lin Fenghan's eyes.

Lin Fenghan came back to his senses, and after a while, he said slightly: "Don't worry, I just suddenly found that I actually took a detour, if it weren't for your reminder, I really have to continue to make mistakes." ”

Mu Xitong smiled gently, as long as he could help Lin Fenghan, there was nothing more worthy of happiness than this.

Lin Fenghan continued to speak: "Xi Tong, the Cold Star Tribulation I just mentioned is extremely powerful, and I will also refine it, so you and I will search for a while to see if we can find some more Cold Star Tribulations, if we can, I want to refine a Cold Star Tribulation first, and then we will continue to act." ”

The reason why Lin Fenghan did this was not only because he wanted to see what he was wrong, but also because his research on the "Xuanyuan Refining Instrument Record" had reached a bottleneck, to see if he could continue to make new breakthroughs through what he had just discovered.

Regarding Lin Fenghan's opinion, Mu Xitong had no objection, "It's just right, just now after passing the Styx Cave, my true yuan consumption is extremely high, and now I happen to be a little tired, so naturally I want to take a rest." ”

Lin Fenghan smiled faintly, Mu Xitong thought about himself everywhere, and couldn't help but feel some fluctuations in his heart.

Soon, Lin Fenghan suppressed the throbbing, and the two of them concentrated on searching carefully in the cold.

The Chill Crystal is indeed a rare thing in the world.

The two of them searched the entire cold land, only to find only eight fist-sized cold pith crystals.

These numbers of cold pith spars are already extremely rare, not to mention anything else, just one cold pith spar is enough to make a guy like Duobao Dao people drool.

Fortunately, with the cold pith spar as the main material, only three pieces can be used, and the remaining five pieces are left for future research.

When Lin Fenghan was about to start researching the refining of the Cold Star Tribulation, he suddenly found a new problem in front of him.

In addition to the need for three cold pith cold diamonds, the Cold Star Tribulation also needs all kinds of bits and pieces of materials, Lin Fenghan has knocked a lot of materials from the Huanxi Sect and the Five Great Buddha Sects, materials, he naturally doesn't care, but the key is that in order to be able to maximize the power of the Cold Star Tribulation, he also needs Geng Jing.

Gengjing is the essence of Gengjin, not to mention the value of Gengjin, let's just say that Gengjin is of extraordinary value in the cultivation realm, among the ordinary flying sword magic weapons, if it can be integrated into Gengjin, its sharpness will rise greatly, and Gengjing is the essence of Gengjin, the sharpness is naturally absolutely exaggerated.

However, Gengjin, although Lin Fenghan happened to have a piece in his hand, and it could also be used instead of Gengjing, but in this way, not only the power of the Cold Star Tribulation would be greatly reduced, but even Lin Fenghan's research would be weakened.

Mu Xi's pupils were as thin as silk, and her red lips opened lightly, "Brother Han, are there any difficulties?"

Lin Fenghan sighed slightly, "The refining of the Cold Star Tribulation is still missing a key material. ”

Mu Xitong understood Lin Fenghan's distress, Yurong was gloomy, and said, "So, I don't know which material is missing?"

"Gengjing!"

Lin Fenghan said the name of the material, and immediately heard Mu Xitong's exclamation, no wonder, a rare thing like Gengjing is indeed a little too difficult to find.

Who knows, just when Lin Fenghan was at a loss, Mu Xi's big eyes flickered, and he said, "Brother Han, but this thing?"

Lin Fenghan looked at him suspiciously.

Mu Xitong was holding a fist-sized golden stone in his hand, which was emitting a dark golden light.

Lin Fenghan said in disbelief, "How do you have Gengjing?"

The corners of Mu Xitong's mouth curved slightly, and he smiled: "Someone else gave it!"

Lin Fenghan opened his mouth, speechless for a while, it was good to be the saint of the Taiqing Sect, and even such a rare thing as Gengjing could be received as a gift.

Dissipating the strange thoughts, Lin Feng said coldly: "In this way, you will be able to refine the Cold Star Tribulation." ”

Mu Xitong simply handed over Geng Jing to Lin Fenghan, not caring about the value of this thing at all.

Lin Feng calmed down and studied carefully, the refining method of the Cold Star Tribulation, after three days, finally comprehended it, and opened his mouth to spew out a dense three-infant yuan fire with emotion, forming a heavenly furnace, and began to refine the magic weapon.

The raging three infant yuan fire burned for a day.

During this period of time, Lin Fenghan always stood there with the same expression, looking up motionlessly at the changes in the materials in the three-color yuan fire, and under his sharp gaze, the materials in the inner were changing subtly according to Lin Fenghan's requirements.

The corners of Lin Fenghan's mouth were slightly raised, and when he saw that the Heavenly Furnace transformed by the Three Infant Yuan Fire, there was a sudden exudation of earth-shattering spiritual pressure and cold energy.

The fire of the Three Infant Yuan Huo was suppressed and extinguished by the cold energy on the spot, which made Mu Xitong, who was on the side, look shocked, thinking that Lin Feng's cold refining device had failed, but after careful observation, Lin Fenghan's face still had a smile on his face, which was not at all like the decadence that would only be revealed when the refining failed.

Don't......

Mu Xitong looked towards the center filled with cold smoke and saw a strange blade, the whole body exuded an amazing aura and cold energy, suspended in the void.

Ancient treasures?

Just by looking at it, Mu Xitong's eyes flashed with all kinds of doubtful light, because at this moment, the fluctuations emitted by the blade when it was only formed, it already made her feel extraordinary, and after identifying it, Mu Xitong was surprised to find that the blade was actually just ...... Foolishness?

"This can't be?" Mu Xitong muttered.

Lin Fenghan said with a slight distraction: "It's still a failure!"

Seeing Lin Fenghan say this, Mu Xitong was also slightly gloomy, and wanted to persuade a few words, but then heard Lin Fenghan continue to mutter: "Obviously, according to the requirements, it should be able to reach the top level of treasures, but it turns out that it can only reach the top of fools." ”

Mu Xi's moist red lips opened, and when he came to his mouth, he swallowed it back.
