Waiting for six days, but only waiting for this result, ye CuO is naturally very depressed, but there is no good way.

At the same time, thinking of his doubts just now, he didn't believe his master's saying that the appetite of the metal sub dragon beast had changed, which was such an unreliable reason.

Previously, on other islands, he found that the metal sub dragons usually eat rare metals first, and then eat those ordinary metal ores after eating them.

So, it's even more impossible to let go of these rare metal ores when the metal sub dragon beast can't eat it, as the bad old man said.

Thinking about it, ye CuO frowned slightly. After a while, he said, "master, I don't think we should put all the metal ores on one island."

"Do you mean to put the metal on several islands near here at the same time?" he said

Ye CuO nodded and said: "yes, if I put metal ores on several islands, maybe they will not all go to one island. As long as they are scattered, the probability of being left alone will be much greater!

Even if the metal Yalong beast is not on the island where the dragon is trapped, it doesn't matter much. At that time, we just need to bring it here! "

Bad old man agreed: "yes, this method is feasible!"

Ye CuO didn't think of this idea before, mainly because his thinking was limited by the trapped dragon array, because only one trapped dragon array could be arranged, so he just wanted to put all the metal ores on this island.

This time, the total value of all kinds of metals placed on the islands has reached tens of millions. If the metals are placed on several islands at the same time, the wealth consumed each time will be hundreds of millions.

If you fail ten or eight times, it will cost billions. However, with Longteng's current financial resources, ye CuO can fully afford it.

Moreover, once you kill the metal sub dragon beast, you can get the golden dragon pearl! In order to get the Golden Dragon bead, in order to break through to the mysterious realm, even if you pay a big price, it is worth it.

So, ye cuodang even made a decision: "that's it!"

Then, he quickly returned to the temporary base, let Longteng people buy a lot of metal ore, and let them hurry to send it.

Because the quantity of this purchase was too large, ye CuO didn't wait for all the metal ores he needed until three days later.

In these three days, the metal sub dragon beast, after returning to its old nest, seemed to be busy digesting the metal in its body and did not leave the island again.

So in this way, yecuo has more time to put metal ores on each island.

However, when he put the metal ore and returned to the temporary base again, a new situation appeared on yalongshou island.

In addition to the previous dozen, on the other side of the island, a group of metallic sub dragons appeared, and the number was as many as 25. In terms of size, there should be seven adults.

After learning about this situation, the bad old man didn't seem to be surprised: "my guess is really right!"

Although Ye CuO was a little surprised, he was also a little surprised. Because of the appearance of this group of metal sub dragons, they would go out to look for food soon, so he didn't have to wait so long.

Sure enough, in the early morning of the next day, this group of metallics left the island and swam towards the sea area where the islands were.

Looking at the figure of more than 20 metal sub dragons, ye CuO was not surprised, but sighed helplessly.

At the same time, his heart can only look forward to good luck, hope that this group of metal dragon beast after full, don't return at the same time.

This time, the speed of the metal sub dragons was much faster than that of the previous group. In the afternoon, they arrived at the sea area.

That is, at this moment, after smelling the metal smell of several islands, they suddenly stopped, as if they were hesitant about which island to go to.

When ye CuO looked forward to their separation, he was disappointed by the choice of the 25 metal dragons, because they just hesitated for less than three seconds, and then all the metal dragons swam in the same direction.

Bad old man suddenly said: "your luck is really bad!"

Hearing the bad old man's words, ye CuO said helplessly, "master, can you stop hitting me?"

After a while, the metal sub dragons boarded an island, found the metal, and immediately began to eat.

They devour very fast, all kinds of hard metal, in their mouth, is directly crushed by sharp teeth, and then swallowed into the abdomen.

After more than an hour, 25 metallics left the island. After a while, ye CuO came to the island.

Soon, ye CuO was puzzled: "they only ate half of these rare metals, but all the other metals were eaten up. What's the reason? Do they want to save it for the next time? "

Not only is Ye CuO puzzled, but even the bad old man is also puzzled. But for a moment, he can't understand why the metal Yalong beast did it.

Ye CuO was puzzled and said, "master, is there any other metal Yalong beast that finds good things, but doesn't eat them all at once, but keeps the habit of eating them again next time?"

"I don't think so..." the old man's tone seemed uncertain.

At this time, ye CuO found that the metal sub dragon beast did not return according to the original way, but swam to another island.

After discovering this abnormal situation, ye CuO became more confused, and then quickly left the island and quietly followed them.

Ye CuO asked the bad old man: "they shouldn't be. They didn't have enough just now, did they?"

"Very likely!"

The bad old man thought for a moment, and then asked the same question: "although I don't know why, if not, how can I explain why they do it?"

Ye CuO thought of the doubt again and couldn't help saying, "this time, will they finish all the metal?"

Just in Ye CuO's and Tsao's doubts, the metal Yalong beast has arrived on the island, and then runs directly to the metal's location. After finding the metal, it opens its mouth and begins to swallow it.

At this moment, ye CuO didn't want to eat enough for this problem, because the behavior of the metal sub dragon beast had helped him to solve his doubts.

More than an hour later, after the metal left the island, ye CuO's figure appeared in the place where the metal ore was placed. It was found that they did not devour all the rare metals, but left about two-thirds of them.
