A huge vortex suddenly appeared in the void. When the vortex leveled, Ying Chengfeng had already drilled out of it.

He circled his eyes and his eyes suddenly lit up.

After giving him a token, the old man in the warehouse immediately sent him into the holy artifact material room.

Although the old man's opinion of outsiders was a little bit extreme, once he determined something, he would be decisive when he did it.

This room is not very big. Compared with the huge hall just now, it can only be said to be a small house.

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

The first treasure he saw was a black iron block the size of a fist. If it were an ordinary person, even if a genius forging spirit master like Tu Jianwei saw it outside the warehouse, he might not be able to recognize it.

However, what can be placed here with caution is definitely not a piece of iron.

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

The essence of Geng metal.

This is actually the essence of Geng Jin.

Geng metal is an extremely rare metal. Only in large metal mines can a little of it be born. The essence of Geng metal is even more a treasure that is only known as the legendary one.

Not to mention the size of this fist, even if it is only a little bit integrated into the holy weapon with a little finger, it can improve the level of the holy weapon 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 would definitely be sure to forge a complete set of Tianji Holy Outfits.

Tianji Holy Outfit, this is thousands of times better than an ordinary holy weapon set.

His lips trembled slightly for a few times, and Ying Chengfeng finally suppressed the greed in his heart. He turned his head, moved his steps hard, and walked away from the Gengjin Essence.

Although this thing is very good and powerful, it is not of much help to Ying Chengfeng at present.

Moreover, the attributes of the Overlord are incompatible with this object, and even if it is forcibly smelted, the maximum power of this object cannot be released.

For powerful forging spirit masters like Ying Chengfeng, it is better to do less things like conquering heavenly things.

As his eyes turned, Ying Chengfeng's eyes condensed again.

He saw a white balloon. Although it was blocked by a ban, Ying Chengfeng could still see that the balloon contained an unparalleled huge chill.

If this coldness rushed out at this moment, Ying Chengfeng would probably be frozen to death here on the spot.

He left carefully. Although Ying Chengfeng could barely be known for his knowledge, he could not tell the origin of this thing for a while.

However, the power of the cold attribute has nothing to do with the improvement of the Overlord's ability, so Ying Chengfeng gave up temporarily.

Slowly, Ying Chengfeng had seen more than ten items.

What opened his eyes was that the value of the items here was far beyond his imagination. If there was really a metaphor, then any thing here could be taken out and worth the same as the things in Xirang and the box that Tu Jianwei gave him at first.

Looking at these hundreds of materials of different origins and attributes, Ying Chengfeng is really a little difficult to get started.

Because any material is something he dreams of, and now he suddenly sees it. If he can easily let it go, it would be strange.

He looked at the token in his hand and was very surprised.

Every month, I can take an item from this material room. Even if I do this reward, I feel incredible.

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

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

In front of him, there was a crystal ball, which was transparent. If it weren't for a faint light film on the outside, Ying Chengfeng would have missed it.

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

There are many treasures that must be explored using spiritual power, and this is even more true for treasures of this level, such as Xirang.

After a moment, Ying Chengfeng frowned and he listened slightly.

In this transparent crystal ball, there seemed to be a strange sound of "swoosh swish swish..." at all times. This sound seemed to be the sound of a sharp blade breaking through the air, but the problem was that he could not see any sword light and sabers at all.

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

Inexplicably, he actually felt nervous, as if the purpose of entering the warehouse this time was to have a fate with this thing. Although this was just a sense of unreasonableness, the sixth sense of the powerful cultivators like them was extremely powerful. Once they had this sense, they naturally refused to let it go.

After a long time, Ying Chengfeng suddenly opened his eyes. He stared at the crystal ball tightly, and his eyes showed ecstasy.

He has read a lot of books and has an extremely rich knowledge under the guidance of the Dan Furnace Spirit. However, if he wants to completely turn this knowledge into experience, it will take a lot of time to practice.

At this moment, after seeing this object, he felt a little. After a detailed search by Zhiling, he finally determined the name and origin of this object.

"Invisible Wind."

Ying Chengfeng murmured, his fists clenched tightly.

Wind is a kind of power in nature.

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

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

Although the Overlord is huge in size and has infinite power, his natural attribute is wind.

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

The power of wind is extremely powerful, but the overlord is best at the simplest and simplest wind power among the wind powers.

Although the wind blade sounds like the lowest level of wind power, if it is released to the extreme, it will definitely not be inferior to any power in the world.

The way is simple. When all power reaches its extreme, it will be transformed into the simplest form.

Wind Blade, the same is true.

This invisible wind is actually a manifestation of the power of the wind blade after it reaches its peak.

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

Ying Chengfeng is sure. If the invisible wind in the crystal ball is integrated into the Overlord's giant axe, this guy's power can be more than doubled.

The overlord holding such a giant axe is not afraid to say that he can be comparable to the darling of heaven and earth, but it will not be much different.

His heart has been moving for countless years, but he is not very sure about how to melt the invisible wind.

With a slight glance at a certain place, Ying Chengfeng said in his heart: "Brother Qiling, I still have to rely on you this time."

Although he did not have this knowledge, the invisible wind was taught by the spirit of the alchemy furnace. I believe it should have some solutions for how to melt it.

In this material room, there may be something more precious than this one, but Ying Chengfeng no longer chooses it.

Only the most suitable treasure is the most powerful treasure.

Ying Chengfeng believes that nothing can help the overlord at this moment more than this thing.

He reached out and gently held up the crystal ball.

The things here are not good deceptions. If they are accidentally broken, they will probably explain their life here.

"boom……"

Just as Ying Chengfeng picked up the crystal ball, a light sound came from a certain direction.

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

After seeing the items 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 frowned slightly and said, "This thing is an invisible wind, a treasure that a predecessor of our Holy Church accidentally obtained. However, this thing is mysterious and has boundless power. Over the years, no one can control it. Not to mention integrating it into the holy weapon, it is impossible to even find a clue. Therefore, it has been put here."

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 one."

Ying Chengfeng smiled bitterly, but he thought to himself that he would not be able to answer this question unless he would invite the spirit of the alchemy furnace and weapon out now.

"Hey, senior, I still want to give it a try." Ying Chengfeng hesitated for a long time and insisted.

The old man shook his head slightly and said helplessly: "Okay, it's okay to give it a try. But I have a condition."

"Please say it, always."

"If you change your mind, don't force yourself to take this item back. I'll allow you to choose again."

Ying Chengfeng was stunned, grateful in his heart, bowed deeply to the old man, and said, "Thank you, senior." If the thanks from the previous few times were also perfunctory, then this time, Ying Chengfeng was definitely willing.

The old man waved his hand gently and said, "The material room has been selected, so let's go to the pharmacy now."

He stretched out his hand and pulled Ying Chengfeng back gently, and a whirlpool suddenly appeared behind Ying Chengfeng. When Ying Chengfeng's body entered the whirlpool, the space immediately twisted. After a moment, Ying Chengfeng's body disappeared and the whirlpool disappeared.

This old man's control of space power has reached a level of superb level.

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

After the old man sent Ying Chengfeng away, his eyes turned around in the material room. Then he arrived at the table where the invisible wind was originally filled.

He reached out and patted it lightly in a certain place, and something flew over and fell lightly onto the table, replacing the invisible wind.

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