"Liu Yu, I contacted you to tell you that the robot team I sent to the mutated forest to mine fire attribute energy stones has set off, and it is estimated that at night, it will be able to reach the veins of fire attribute energy stones."

Liu Yu was slightly stunned, he still remembered that Mu Yan said last time that the robots in the flagship were all made for battle, and if you want to use these robots to mine energy stones, you also need to transform some modules.

But I didn't expect that Mu Yan's transformation efficiency was so high, and it only took more than a week to transform a batch of them.

After a slight shock, Liu Yu opened his mouth and asked, "Captain Mu Yan, how many robots are there in the first batch you sent over?" ”

"Not much, only a thousand." Mu Yan said casually.

Liu Yu listened to Mu Yan's understated tone, and was almost choked by his own saliva, "It's not much, it's only a thousand" This tone really kills all the scientific research workers on the Kalan planet in minutes......

Without waiting for Liu Yu to speak, Mu Yan continued: "After these robots pass, a signal point is established, and I can also check the situation and scale of the vein through the signal point, if the scale of the energy stone vein is large, I will send some more robots over." ”

Liu Yu nodded, trying his best to make his expression look professional, and asked, "Is there anything I need to do in terms of mining fire attribute energy stones?" ”

Mu Yan shook his head and said, "No need, my robot can complete all the mining work." ”

After ending the call with Mu Yan, Liu Yu began to ponder. Mu Yan didn't know the complex relationship between the major forces of the human race, but he understood it very well.

Take this ruby vein as an example, the ruby vein is considered to have been extorted by him from the Xiahou family.

Although the ownership of the ruby vein is now in his hands, it is estimated that the Xiahou family will not relax its monitoring of that vein.

At that time, if the Xiahou family discovers that the people who go to that vein to mine ore are all robots, it is difficult to guarantee that the Xiahou family will not have doubts about his identity.

Although there are also some robot guards in his Potion Villa now, there are only a hundred of them, which is not much, and it will not attract anyone's special attention.

But if all of his ruby veins were mined using a large number of robots, it would be easy for others to associate them with something else.

For example, the Xiahou family would suspect that he was cooperating with a force that specialized in robots, otherwise, he would not have been able to make so many robots as a pharmacist.

Liu Yu thought about what kind of impact it would have on him and Mu Yan if the outside world guessed that he might have a cooperative relationship with other unknown forces.

In fact, as far as he is concerned, he doesn't care about all kinds of speculation from the outside world. Because that speculation would not hurt his interests. Even, the random speculation of all parties is still beneficial to him, and he can use the speculation of all parties to pull the tiger skin as a banner!

After all, an unknown force with a large number of robots is definitely a weapon that can deter all sides.

However, with the speculation of the outside world, there will definitely be forces that will list him as a special focus and try to dig out a trace of information about the mysterious forces on that side from him.

He was afraid that because of this, the existence of Mu Yan and the flagship would be exposed!

Mu Yan's existence, it's not a joke, she is an intelligent life.

At least, from the overall perspective of the entire interstellar world, intelligent beings and human beings who have awakened their self-consciousness are mortal enemies!

When he thought of this, Liu Yu couldn't help but sigh.

It's a pity that regarding the mining of ruby veins, Liu Yu really has no more efficient way than robot mining. However, the large-scale use of robot mining is indeed too big and too difficult to conceal.

And all he can do is to do his meager strength and try not to let others find out about Mu Yan's existence!

After figuring this out, Liu Yu immediately called the four robot leaders and ordered them to take fifty robots to patrol around the ruby veins in the mutated forest, stun those people who had bad intentions left behind, and temporarily controlled them.

Those people must not be allowed to see the thousand mining robots sent by Mu Yan.

Until the thousand mining robots sent by Mu Yan entered the inside of the ore vein, and then let the spies left behind by these people leave!

Seeing the four robot leaders lead the order to leave, Liu Yu sighed secretly, "I hope that by doing this, the matter of allowing a large number of robots to enter the mine vein will be hidden from the eyes and ears of the Xiahou family." ”

The speed of the four robot leaders is very fast, and in less than an hour, he has already sent a message to Liu Yu, and the four spies who stayed in the mutation forest have been controlled, and at the same time, the four robot leaders also told Liu Yu a message.

It turned out that the actions of the four robots had been known to Mu Yan, and Mu Yan also relayed a message to Liu Yu through the mouths of the four robots.

She asked the four major robots to tell Liu Yu that his worries were unnecessary, and the thousand mining robots she sent were all optically invisible.

As long as those robots turn on optical invisibility, they can't see those robots with human eyesight.

Although the optical invisibility ability is more energy-intensive, if she just lets the robot rush in the state of optical invisibility, she can still afford that kind of consumption.

At the same time, Mu Yan also asked the leaders of the four robots to tell Liu Yu that she had asked the thousand robots to remain invisible until they arrived at the location of the fire attribute energy stone veins.

Only after entering the inside of the vein will the mining robot turn off the optical invisibility.

After hearing this news, Liu Yu breathed a long sigh of relief, since those robots can achieve the degree of optical invisibility, then the possibility of exposure is much smaller.

……

On the same day, in the early hours of the morning, Liu Yu received a notice from the leaders of the four robots that the thousand mining-type robots sent by Mu Yan had all entered the inside of the fire attribute energy stone vein.

And the four spies who were originally controlled by them have also been released.

……

On the second day, the Xiahou family set off a storm.

The head of the Xiahou family and several high-ranking members of the Xiahou family, when they handed over the ruby vein, left a hand and let four specially trained people stay in the position around the ruby vein to observe what Liu Yu would do with the ruby vein next.

But just after a little past yesterday morning, the head of the Xiahou family and several high-ranking officials of the Xiahou family received a report from four spies at the same time.

They said that at noon, they were inexplicably knocked unconscious, after which they were controlled by several robots. But the strangest thing to them was that after midnight, those robots inexplicably let them go!

It's just that when they want to continue to dive back into the ruby veins to explore, they will always be intercepted by robots patrolling everywhere!
