A huge whirlpool suddenly appeared in the void, and when the whirlpool calmed down, Ying Chengfeng had already drilled out of it.

He looked around, and his eyes lit up.

After giving him the token, the old man in the treasury immediately sent him into the sacristy material room.

Although the old man's opinion of outsiders is a little extreme, once he determines something, he will act vigorously and resolutely.

This room is not very large, compared to the huge hall just now, it can only be said to be a small room.

However, the items in this room are much more precious.

The first treasure he saw was a fist-sized piece of black iron, if it was an ordinary person, even if a knighthood forging spirit master like Tu Jianwei saw it outside the treasury, he might not be able to recognize it.

However, what can be carefully placed here will definitely not be a piece of mortal iron.

Taking a step forward, the divine thought swept over the black iron block layer by layer. Slowly, Ying Chengfeng's eyes lit up.

The essence of heptane.

This turned out to be a piece of the essence of heptogold.

Heptane gold is an extremely rare metal, and it is only possible to give birth to such a point in large metal mines. And the essence of Gengjin is a treasure that only has legends.

Not to mention this fist-sized piece, even if only a little bit of the little finger is integrated into the holy soldier, it can make the grade of the holy soldier rise to a higher level.

He took a deep breath, and a hint of greed flashed in his eyes.

If this piece of Gengjin Essence fell into his hands, he was absolutely sure that he would forge a complete set of Heavenly Jealous Holy Suits.

Heavenly Jealous Holy Suit, this is thousands of times better than an ordinary Sacred Weapon Suit.

Her lips trembled slightly, and Ying Chengfeng finally suppressed the greed in her heart. He turned his head, struggled to move his steps, and walked away from the spirit of Gengjin.

This stuff is good though. It's powerful. But it is not of much help to Yingchengfeng at present.

Moreover, the attributes of the overlord are not in harmony with this thing, even if it is forcibly smelted. Unable to release the maximum power of this object.

For a powerful forging spirit master like Ying Chengfeng, it would be better to do less of this kind of thing.

With a turn of his gaze, Ying Chengfeng's eyes condensed again.

He saw a mass of white balloons. Although it was blocked by a prohibition, even with his eyesight, Ying Chengfeng could still see that this balloon contained an incomparably huge chill.

If this kind of chill rushes out at this moment, then Ying Chengfeng is afraid that he will be frozen to death here on the spot.

Leaving cautiously, although Ying Chengfeng can barely be called well-informed, he can't judge the origin of this thing for a while.

However, the power of the cold attribute also has little to do with the ability improvement of the overlord, so Ying Chengfeng will give up for the time being.

Slowly. Ying Chengfeng has already seen more than ten items.

What opened his eyes was that the value of the items here was far beyond his imagination. If there really is a parable. So take out whatever is here. It can be similar to the value of the things in the box that Tu Jianwei originally gave him.

Looking at these hundreds of materials with different origins and attributes, Ying Chengfeng is really difficult to start.

Because any kind of material is for him. It's all something I've always dreamed of, and now that I've suddenly seen it, it's strange if I can easily let it go.

Glancing at the token in his hand, he was pleasantly surprised.

Every month, being able to take an item from this material room is a reward that even he has an incredible feeling.

Shaking his head, Ying Chengfeng's gaze continued to move.

Suddenly, he stopped his gaze, raised his eyebrows slightly, and stared at the object in front of him tightly.

In front of his eyes, there was a crystal ball, this sphere was transparent, if it weren't for a faint film of light on the outside, it would almost make Ying Chengfeng miss it.

Taking a step forward, Ying Chengfeng was lucky enough for his eyesight, and even his spiritual power was released at the same time.

There are many treasures that must be explored using spiritual power, and even more so for a treasure of the level of Si Yang.

After a moment, Ying Chengfeng's brows furrowed, and he listened slightly.

In this transparent crystal ball, there seems to be a strange sound of "whooshing ......" at all times. The sound was like the sound of a sharp blade breaking through the air, but the problem was that he couldn't see any sword or sword shadow at all.

The eyeballs rolled slightly, Ying Chengfeng closed his eyes slightly, and the wisdom spirit in his mind was running at high speed, analyzing the origin of this thing.

Inexplicably, he actually had a nervous feeling, as if the purpose of his entry into the treasury this time was to have a relationship with this thing. Although this was just an unreasonable feeling, the sixth sense of a cultivator like them was extremely powerful, and once they had this sense, they naturally refused to let it go.

After a long time, Ying Chengfeng suddenly opened his eyes, and he stared at the crystal ball deadly, his eyes revealing ecstasy.

He was already well-read, and under the guidance of the Dan Furnace Spirit, he possessed an incomparably wealth of knowledge. However, it takes a lot of time to hone this knowledge if you want to fully turn it into experience.

Just like at this moment, after he saw it, he felt something. After a detailed search by Zhiling, the name and origin of the object were finally determined.

"Invisible winds. ”

Ying Chengfeng muttered in his mouth, his fists clenched a little.

Wind is a force in nature.

As long as you are in an open place or an alley, you can always feel the presence of the wind.

The power of the wind is one of the most powerful natural elements in the world.

Although the overlord is huge and powerful, his natural attribute is wind.

This can be seen from the power of the wind that he unleashed when he was promoted to the knighthood.

The power of the wind is extremely powerful, but what the overlord is best at is the simplest and most simple kind of wind power, the wind blade.

Although the Wind Blade sounds like the lowest level of wind power, its power can be unleashed to the extreme. But it will never be inferior to any power in the world.

The road to simplicity. When all power is at its extreme, it is transformed into its simplest form.

Wind Blade, no less.

This invisible wind is actually a manifestation of the power of the wind blade after it has climbed to the extreme.

This crystal ball looks transparent. There is nothing in it either. But in fact, inside the crystal ball, there are countless invisible winds flying and raging.

Ying Chengfeng can be sure. If the invisible wind in the crystal ball is integrated into the overlord's giant axe, it can more than double the strength of this guy.

The overlord with such a huge axe in his hand can't say that he can compete with the darling of heaven and earth, but it won't be too different.

His heart had been spinning for countless years, but he wasn't too sure about how to smelt the invisible wind.

Glancing slightly towards a certain place, Ying Chengfeng secretly said in his heart: "Brother Instrument Spirit, this time it still depends on you." ”

Although he didn't have this knowledge, the invisible wind was something that the spirit of the Dan Furnace had imparted, and presumably it had a good understanding of how to smelt. There should be some way.

In this material room, there may be something more precious than this one, but Ying Chengfeng has stopped picking it.

Only the most suitable treasures. is the most powerful treasure.

Ying Chengfeng believes. There is nothing more powerful than this to help the Overlord at this moment.

Reaching out, he gently picked up the crystal ball.

There's not much of a good thing in this. If you accidentally break it, I'm afraid that this little life of yours will have to be explained here.

"Boom ......"

At the moment when Ying Chengfeng picked up the crystal ball, a soft sound came from a certain direction.

Then, the old man appeared in front of him like a ghost.

After seeing the item in Ying Chengfeng's hand, the old man was slightly stunned and said, "How do you choose this item." ”

Ying Chengfeng smiled slightly and said, "What's wrong with this thing." ”

The old man's brows furrowed slightly, and he said, "This thing is an invisible wind, a treasure that one of our Holy Sect's predecessors inadvertently obtained. However, this thing is mysterious and powerful, and for generations, many forging masters have not been able to control it, let alone integrate it into the Holy Soldiers, even if they want to touch the slightest clue, it is absolutely impossible. So, it's been here all along. ”

Ying Chengfeng's face changed slightly, as if he was a little worried.

The old man said slowly: "If you are not sure, then change it." ”

Ying Chengfeng smiled bitterly, but he secretly said in his heart, unless he invited the Dan Furnace Spirit out now, he really couldn't answer this question.

"Hey, seniors, juniors still want to give it a try. Ying Chengfeng hesitated for a long time, but still insisted.

The old man shook his head slightly, and said helplessly: "Okay, just try." However, the old man has one condition. ”

"Tell me. ”

"If you change your mind, don't force your hands and take it back, and the old man will allow you to pick it again. ”

Ying Chengfeng was stunned for a moment, grateful, bowed deeply to the old man, and said, "Thank you seniors." "If the previous thank-you were still perfunctory, then this time, Ying Chengfeng was definitely willing.

The old man waved his hand lightly and said, "The material room has been selected, let's go to the Dan Pharmacy." ”

He stretched out his hand and pulled Ying Chengfeng, and gently pushed back, and a whirlpool suddenly appeared behind Ying Chengfeng. And when Ying Chengfeng's body entered the whirlpool, this space immediately distorted, and after a while, Ying Chengfeng's body disappeared, and the whirlpool disappeared.

This old man's manipulation of spatial power has reached the point of being superb.

Compared to it, Lingta Zhenren and Wu Lao are like two little guys who are learning to speak, and their control skills of spatial power are not worth mentioning.

After the old man sent Ying Chengfeng away, his gaze turned around in the material room. Then he came to the table where the invisible wind had been in place.

He stretched out his hand and patted it lightly in a certain place, and an object suddenly flew over and landed lightly on the table, taking the place of the invisible wind.

The number of treasures in this room has returned to its original state again.

The old man sighed lightly and muttered, "Invisible Wind, I hope he can succeed in forging it." ”
