In recent days, Chu Feng has been either busy cultivating martial arts, or busy killing people and hurrying, so he doesn't have time to calm down and study this quaint and mysterious storage bag, and he hasn't even taken inventory of the various items in the storage bag.

At this moment, Chu Feng probed in the storage bag.

The first thing I saw was naturally the Thunder King Beast.

At this time, the Thunder King Beast was standing there like a leisurely horse, shaking its head and tail, its expression was very leisurely, and it was not irritable at all.

As expected, the gold ingots, silver ingots, and War Shadow Iron in the storage bag were like a mountain, piled up in large piles, not far from the side of the Thunder King Beast.

The storage bag has the function of producing metal items, and after these days of continuous production, it is not surprising that there are so many gold and silver ingots, War Shadow Iron and other items in the bag.

To Chu Feng's surprise, there were two more spear heads more than a foot long in the storage bag!

These two spear heads were the spear heads of the Overlord Shadow Chasing Gun that Chu Feng had put in before.

The barrel of the Overlord Shadow Chasing Gun is wooden, but the gun head is made of gold and steel, which is naturally a metal item, so after a few days of production, the gun barrel has not been created, but only two identical gun heads have been created.

Except for the metallic items, all other non-metallic items, including the secret book, the golden ticket, the Cave Moon Flying Orb, and the two puppets, were still in their original form, and no artifacts appeared.

"Well, that's good! I'll have to take advantage of this opportunity to be patient and pay full attention, and take a good look at the inside of the storage bag, maybe I can get a glimpse of the mystery!"

Thinking like this in his heart, Chu Feng immediately cleared out all the metal items in the storage bag, and none of the metal items were left in the bag.

As soon as it was cleaned up like this, all the gold ingots, silver ingots, and War Shadow Iron were immediately piled up into two large piles, and the room was suddenly golden and dazzling.

And the space in the storage bag has suddenly enlarged a lot.

Chu Feng picked up a piece of gold ingot, put it into the storage bag, and his eyes were fixed on this gold ingot.

I saw that after the gold ingots fell into the storage bag, the space around the bag immediately generated a cloud of colored mist, and slowly approached the gold ingot.

Chu Feng saw it, there were a total of five directions, a total of five colored mist, and each direction had a qi.

The five colored mist were dazzling gold, dark wood, clear and transparent water, a fiery yellow fire, and an earthy yellowish brown.

"Well, these five kinds of colored mist, with bright colors, will not be accidental, they should correspond to the five elements of metal, wood, water, fire, and earth!"

Chu Feng thought to himself while carefully observing the changes in the storage bag.

These five clouds of mist, which symbolize the elements of the five elements, approached this gold ingot from five different directions, and the mist was thick and light, and the speed was fast and slow.

The thickest and fastest-moving fog is the golden mist, followed by the wood mist, followed by the fire mist, and the earth mist.

Only the clear and transparent water-colored mist seemed to be only such a thin layer, as thin as light smoke, and the movement speed of this water-colored mist was also very slow.

At this time, the golden mist, wood-colored mist, fire-colored mist, and earth-colored mist had all approached the surroundings of the gold ingots one after another, only this water-colored mist was very backward, and it was still struggling to move towards the gold ingots.

"Hmm, what does this mean? This shows that the water element in the storage bag is not only very lacking, but also not active enough!" Seeing this scene, Chu Feng's heart suddenly moved, as if he had an understanding.

The intensity and activity of this water-colored mist are four or five times lower than that of the other four elements, which is obviously a drag on the storage zài.

After a few breaths, the water-colored mist finally arrived next to the gold ingot.

The next moment!

As soon as the mist of these five elements converged, it immediately tumbled and rolled like a dark cloud, blending and converging with each other, and in the blink of an eye, the five single colors merged into one complex color.

Five clouds of mist quickly merged into one.

This multicolored mist wraps this piece of gold ingot, the mist is like boiling water, gathering and scattering, with this repeated change of the mist, the mist itself is becoming more and more thick and heavy, the shape of the air mass is more and more regular, and the color is more and more single.

Soon, the multicolored mist stopped churning and scattering, and even disappeared.

And next to this gold ingot, there is an extra gold ingot! The two gold ingots are exactly the same, not bad at all!

Chu Feng witnessed the whole process of creating items in the storage bag, and did not miss a single detail, and he could be regarded as touching a little bit of the mystery of creation, but it was not easy to draw a conclusion.

Next, Chu Feng took a few more gold ingots, also put them into the storage bag, and also watched the whole process of making gold ingots in the storage bag intently.

After repeated observation like this, after half an hour, Chu Feng finally dared to make a conclusion.

This storage bag can produce exactly the same items, not out of thin air, but by using the five elements in the storage bag to reproduce the items as they are.

When it comes to the five elements in the storage bag, it is obvious that the water element is dragging its feet, not only in small amounts, but also not active enough.

"Looking at the situation of this creation, if the water element can keep up, the time to create a piece of gold ingots will be greatly reduced! Now it seems that the other four elements are abundant, but the water element is too lacking! The five elements are indispensable!"

Chu Feng already knew it in his heart.

But how do you increase the amount of water in the bag and make it active at the same time?

Chu Feng walked around the room, thinking about this question.

In Chu Feng's opinion, this storage bag is like an old ox pulling a plow.

The old ox pulls the plough and needs the support of energy, and only after eating a lot of grass and having enough strength can the iron plough be pulled.

And this storage bag creation is the same reason, it needs the support of a kind of energy to continue to produce items.

Here's the question, the old cow needs to eat grass to get energy, what does this storage bag have to "eat" in order to get the energy to create?

Now it seems that the most missing element of the storage bag is the water element. In other words, the water element in the storage bag is now lifeless, as if it is about to fall asleep.

Could it be that you need to add a little water to this storage bag and see if it needs the energy, can you activate some of the sleeping water elementals?

Chu Feng immediately shook his head and denied this somewhat crazy idea, many high-level items in the martial arts world are meant to avoid water, add water to the storage bag, in case this is not the case, the creation function of the storage bag will be lost, and it will be useless to regret the green intestines!

However, Chu Feng recognized a situation, at the moment, this storage bag did not exert its full effect at all, it was only equivalent to being in a half-awake state, and now something was needed to activate it, so that it could exert its full effect and maximize its value.

"What should I use to activate the lifeless water element in the storage bag?"

Chu Feng thought about it for a long time, but he couldn't figure it out, the key was that this storage bag was a treasure, and he didn't dare to try something casually.

And thinking of the origin of this storage bag, this is still a year ago, when Chu Feng was still working as a bitter soldier in the Fear Gate, a middle-aged worker gave it to Chu Feng before he died, which was a second-hand storage bag. And the middle-aged worker only bought it casually in the market, and it was purely accidental to own this storage bag.

After Chu Feng obtained this storage bag, he didn't find anything unusual about it, and it was only after escaping from the Terror Gate a few months ago that he was shocked to find that this storage bag could produce metallic items.

"Strange! Why didn't this bag come into being made sooner rather than later, but when I was fleeing, it suddenly had the function of making things in my most critical situation? Could it be that I accidentally added something to this storage bag?"

This time, I thought about it for another half an hour, and I was still puzzled.

"Hey, forget it, don't rack your brains anymore! Since this storage bag is a treasure, it should have been left by someone thousands of years ago, and it may be recorded in the martial arts classics! When you have time to go back, you may find something to gain from flipping through the relevant classics!"

Chu Feng immediately let go of the obsession in his heart and no longer thought about this curse-like question.

"Now it seems that the function of the storage bag to produce metal items is completely normal! I hope that after rushing to the Wuhan Snow Clan, the function of the storage bag will remain normal, but it will not fail on the spot!"

Thinking in his heart, Chu Feng put away the metal items all over the ground again.
