Refining world crystals into high-purity world coins requires not high technological content, so it should be easy to do it. After he purchases the production line, the cosmic crystals in his hands can be directly converted into world coins used by the gods!

With this expectation, Lan Tianyu's interest in digging cosmic crystals suddenly increased significantly. He simply took out all the combat robots, defense robots, ordinary robots, etc. under his reserve. Regardless of the efficiency, all robots could dig.

At the end of the day, the blue sky rain brought together all the cosmic crystals excavated by the robot, and it actually reached an astonishing 1.05 million square meters!

What is the concept of 1.05 million square cosmic crystal? That is 105 world coins, which is a huge fortune for the powerful man of level nine!

Of course, such an amazing harvest was only when the first day was first excavated. The next day, the harvest of cosmic crystals dropped by nearly half, with only 640,000 square meters of cosmic crystals.

For eight consecutive days, the Blue Sky Rain dug out a total of 3.27 million square meters of cosmic crystals. After the eighth day, the cosmic crystals in the central area were almost dug out by the Blue Sky Rain, and the harvest on the ninth day was less than 30,000 square meters.

On the tenth day, Lan Tianyu discovered other adventurers from afar, and put away all the robots and digged the universe crystal alone.

The first wave came with a four-person team. They were very fast. As soon as Lan Tianyu put away the robot, these people appeared in his sight.

The four people were surprised to see someone getting one step earlier than them. They looked at Lan Tianyu carefully. Seeing Lan Tianyu ignored them and still digging the universe crystal quickly. They took some care of it and looked at each other. They no longer paid attention to Lan Tianyu, but they all looked at the castle in the distance.

It is obvious that this ancient castle should be the treasure land in the middle of the world!

The four of them tried their best along the way, and even a piece of universe crystal was not excavated. In order to get the first to feel the core area. If the treasure land was in the central area, they would make a big profit.

Now seeing the towering castle, the four of them wished they could enter it immediately. Fortunately, they were not ordinary people, and even though they were excited, they still maintained a little rationality.

One of the green-skinned middle-aged men said: "The Lord of the Thunder Realm is not an ordinary person. This castle may hide fatal dangers. Let's be careful. It is best to use a robot to explore the way first. If there is no danger, we are going in."

"Senior brother makes sense. The more critical the moment, the more we should be careful not to fail, and that would be more costly." Another silver armored man echoed.

A man holding a long sword answered: "I have not brought any of those robots that have no effect. However, I just got a cub of a spirit beast swallowing the sky wolf some time ago, otherwise I would let this cub test it?"

"It is rare for the spirit beast to swallow the sky wolf's cub. If it is just abandoned like this, it would be a pity." The man in black armor said regretfully.

"Didn't you carry a robot? It seems that we need to prepare more fully when we go on missions in the future." The green-skinned middle-aged man looked at the man holding the long sword, "Junior Brother Fei Yan, it seems that you can only let your Tianlang Swallow cub test it. If you die in danger, no matter whether you can get the treasure, the three of us will compensate you."

"Although the swallowing wolf cub is rare, the lives of our brothers are more important. If they die, they will die as much as possible." Jian Yan summoned the swallowing wolf cub and stroked the top of his head, feeling a little reluctant.

After a while, Ji Yan made up his mind to order the Swallow's cubs to enter the castle to investigate first.

When the Tianlang cub arrived at the gate and hit the gate of the castle, Lan Tianyu stopped digging and turned his attention to it.

Without any surprises, another electric arc flashed, and the swallowing wolf cub didn't even have time to make a scream, and it was electrocuted into coke.

Seeing the terrifying scene in front of you, the four of you felt palpitations and then they were a little depressed.

Such a terrible protective method was completely shattered. Their plan to enter the treasure first was completely destroyed.

Since there is no hope of entering the castle first, the only thing that can be done now is to patiently dig the universe crystal. But looking around, the entire central area is full of potholes and traces of just being dug. It is obvious that the person who took the lead has almost dug up the entire central area in advance.

"Senior Brother Mingwei, it seems that this person has dug a lot of cosmic crystals. He has dug up the entire central area. How many cosmic crystals do you think he has obtained?" said the Silver Armor Man.

"The core area of ​​the world's middle realm has always been the area where the most universe crystals are stored. This is the world's middle realm of the top realm master. It has such a large range. The space crystals stored are at least one million square meters!!" Ming Wei's eyes were full of greed, "Junior Brother Wu, this is simply an unimaginable decisive wealth!"

When they heard the huge numbers of a million square cosmic crystals, the other three people changed their faces and their eyes were full of greed and fanaticism.

Silver Armored Man continued: "Our speed is already very fast. He is at most a day or two earlier than us. How do you think he dug up all the core areas of such a large range? I don't know if this has anything to do with his strength?"

"It should not have much to do with his strength. The biggest possibility is that he happens to carry a lot of excavation robots with him. Since he can enter the Thunder World, he is no exception. At most, he is the 9th-level star power!" Ming Wei analyzed.

Normally, even for the ownership of ten thousand square cosmic crystals, they are enough to sacrifice their lives! Now there is a huge temptation of one million square cosmic crystals, and their opponents are at most like them, and they are all stellar-level ninth-level strength. In this case, there is no need to consider it. The four nodded at the same time, preparing to be the lucky one who took the lead.

Seeing the four people walking towards him and vaguely surrounding him, Lan Tianyu already understood what they meant.

These four people came so quickly that they would definitely not have time to dig the universe crystals on the way and kill the four star-level powerful men. There would be no big deal of oil and water. Lan Tianyu was ready to give them a chance to survive.

After the four people stopped a hundred meters away from him, Lan Tianyu said: "Opportunities always coexist with risks. I advise you to consider it before taking action."

When Mingwei heard Lan Tianyu's words, he smiled instead. He was sure that the other party was afraid and said, "You are right. If you don't take any risks, how can you get something? You can only blame you for coming too quickly, but you don't know how to control yourself, and you actually dug up the entire core area."
