In the northern part of the Yanlong Swamp, in a valley shrouded in smoke.

Qin Feng sat cross-legged, and in front of him, there was a swarthy Night Demon Furnace.

Xuan Ying was right next to Qin Feng. I have to say that seeing the night demon furnace with seven fire eyes really surprised this Yanhuang princess, although Xuan Ying doesn't know soul refining, but she also knows that the refining furnace with seven fire eyes is already qualified to be on the "Heaven and Earth Double List".

The so-called double list of heaven and earth refers to the ranking list of the refining furnace, which is divided into two sheets: "Tiangong List" and "Geotechnical List". The refining furnaces of the Tiangong List are basically legendary treasures, and they are rare for idlers to see. Although the refining furnace of the ground work list is not as valuable as the heavenly work list, it is also quite precious and rare.

What surprised Xuan Ying was that Qin Feng, a sixteen or seventeen-year-old young soul man, actually had a Night Demon Furnace.

However, Xuan Ying's resentment towards Qin Feng was still unsubsidy, and she was a little unkind when she spoke: "It's too wasteful for you to use a refining furnace of this level." With your flesh and qi cultivation, you won't need seven fire eyes at all. ”

"What you said has some truth, I really don't need the seven fire eyes now," Qin Feng's face was relaxed, and he didn't get angry at all because of Xuan Ying's tone, "However, it wouldn't be a waste to say that it was wasteful." Just because you can't use it now doesn't mean you won't need it in the future. Soul people have a furnace that they are accustomed to, and now that they are familiar with the characteristics of this Daredevil furnace, they will not need to change the furnace in the future. ”

"Nonsense. If you want to perfectly exploit the potential of this refining furnace, you need at least a soul master of the sixth order or so to do it. In the entire Chiyang Kingdom, there is not a single sixth-order soul person, do you think you can be the first?" Xuan Ying sarcastically disdainfully.

"Sixth-Order Soul Person?"

Qin Feng shook his head a little amusedly, and did not continue to argue with Xuan Ying. His left hand pressed down on the three fire eyes, and under the infusion of blood qi, the steps of igniting the fire began.

A few minutes later, the flames rose. Qin Feng slowly put the Yanyan Tiger King Sword into it, carefully manipulating the flame temperature to heat up the Yanyan Tiger King Sword.

"What are you doing here, hasn't this sword been successfully refined?" asked Xuan Ying curiously.

"The innate material of this sword is too poor, which limits its power. I'm going to use my newfound refinement to sublimate its material and make it even more powerful. Qin Feng didn't hide it.

"The newly acquired method of refinement?" Xuan Ying said, "Could it be those fragments you found in the treasure trove of the old thief of the Smoke Dragon?"

Qin Feng nodded.

"I'm afraid it's not that simple, right? If you can learn it by comparing a few fragments, your soul refining realm won't attach so much importance to the inheritance of master and apprentice. Xuan Ying obviously didn't believe that Qin Feng could do it.

The method of refinement, improving the innate material of the beast soul soldier, no matter how you look at it, is not a low-end soul refining method. The advanced soul refining method often requires the master's words and deeds, and it takes a long time to gradually master it. How long did it take for Qin Feng to get the remnants of the method of refinement?

"Hehe, then you'll be optimistic. ”

Qin Feng didn't argue and decided to speak with facts. Since he signed a master-servant blood contract with Xuan Ying, Qin Feng must of course show his ability appropriately, so as to win Xuan Ying's respect.

Under the scorching flames, the Yanyan Tiger King Sword gradually showed a hint of melting, and on the surface of the sword body, there were drops of liquid ink iron circulating.

"Almost. ”

Qin Feng threw a grain of Xuansha into the refining furnace, and under the scorching flames, the Xuansha quickly exploded, turning into extremely fine, dust-like particles, and enveloping the entire sword body of the Yanyan Tiger King Sword.

Qin Feng pressed the fire eye with his left hand, continuously infusing blood and qi, and the seal of his right hand quietly changed, and a trace of soul power extended into the refining furnace.

Qin Feng's right hand, which changed thirty-six times in a row, was exactly the seal of the method of refinement mentioned in the golden silk fragment. Even if outsiders see this set of seals, they can't learn the method of refinement, because only the gestures have no matching soul power, and they have no effect.

Xuan Ying was originally a little disdainful, but seeing that the speed of the seal in Qin Feng's right hand was changing faster and faster, and there was actually a trace of phantom, the disdain in her heart gradually converged. Judging from Qin Feng's performance after he started to ignite the fire, he was proficient step by step, without the slightest sense of crampedness.

"Qin Feng is less than seventeen years old this year, could it be that while he has cultivated to the Spirit Transformation Realm, he also has a not weak attainment in the way of soul refining?" Xuan Ying thought secretly in her heart.

A crackling sound sounded, interrupting Xuan Sakura's thoughts. She looked up, but saw that Qin Feng's thirty-six handprint recipes had been completed, and the two fingers of her right hand were pressed on the center of her eyebrows, and streams of soul power continued to pour out, regulating the changes in the Yanyan Tiger King Sword in the refining furnace.

Xuan Ying couldn't see the changes in the refining furnace, but Qin Feng could perceive it clearly with his soul power. The sword body of the Yanyan Tiger King Sword, under the action of Xuansha, has begun to catalyze, transforming from an inky iron material to an unknown material.

Qin Feng sighed, this change at least showed that the method of refining was effective.

Under Qin Feng's soul power induction, the fine particles of Xuansha were infiltrating the sword body of the Yanyan Tiger King Sword step by step, changing the structure of the ink iron step by step at an extremely subtle level.

Xuansha is worthy of being an excellent auxiliary material for refining. However, without the cooperation of the method of refinement, the effect of the sand will be greatly reduced.

For example, ordinary soul people can directly use sand to upgrade the Beast Soul Soldier, at most, the hardness and sharpness of the Beast Soul Soldier will be increased by a grade, but it will not be able to change the grade of the Beast Soul Soldier. And Qin Feng relied on the method of refining and cooperating with Xuansha to upgrade the Beast Soul Soldier, but it was an improvement of the fundamental material of the Beast Soul Soldier, which could make the grade of the Beast Soul Soldier go to a higher level.

After an hour or so of careful training, Qin Feng finally breathed a sigh of relief and withdrew his right hand.

The Smoke Tiger King Sword quietly flew out of the refining furnace.

"Huh?" Xuan Ying frowned slightly, although she didn't know how to refine weapons, she knew the quality of the beast soul soldiers. This Yanyan Tiger King Sword seemed to be a little different from Qin Feng's before he was refined, but she couldn't say what the specific difference was.

"The original material of this sword was ink iron, a second-order metal material. After my refinement, its own material is more compact and pure, removing a large number of impurities, and the quality is between the third and fourth order metal materials. And the inner pill used by the Yanyan Tiger King Sword itself is from a mutated tiger king, and its power is at the peak of the third order! The original ink iron material limits the power of the Yanyan Tiger King's beast soul, and after the material is upgraded, the power of the Yanyan Tiger King's beast soul can be fully utilized. The grade of this sword should have broken through the third order by now, reaching about the middle grade of the fourth order. ”

Qin Feng waved lightly, and the Smoke Flame Tiger King Sword after refining slashed at each other, and a fierce smoke flame sword qi rushed out. There was a bang, and a large bluestone in front of him was cut into two pieces.
