An hour later, one-tenth of the spirit stone mine in the pit disappeared, and a full dozen tons of spirit stone ore were absorbed by the World Tree seedlings, but the World Tree seedlings were only more than one person tall, and the leaves on them were already the size of a baby's palm, and the pieces were shining like jade with a heart-warming luster.

Lu Tianyu was frightened by the appetite of the World Tree seedlings, this is a bottomless pit!

"I'm afraid one spirit vein is not enough for the World Tree seedlings to absorb!"

"If you simply let the World Tree seedlings absorb the spiritual veins, even ten spiritual veins are not enough, but the growth of the World Tree does not completely come from the spiritual veins, the real energy source is still the free energy in the air and the thunder and lightning in the sky, as long as the World Tree seedlings pass through the first stage, the required spiritual stone mines will be reduced to negligible!"

Lu Tianyu breathed a long sigh of relief, his heart was still a little painful, the spirit stone was very important to his future cultivation, and now there are not many spiritual veins left on the earth, it is still the kind of lower grade, if you can save a little, you will have more help.

However, the World Tree is still a seedling, and it will take some time to grow, and it will take at least three years to reach the stage of fruiting.

Suddenly, Lu Tianyu thought of an important thing and said: "Is there a little more number of biochemical people and robots in the city-level interstellar formation, and the resources consumed will not be less." ”

The smallest village-level spaceship is equipped with 500 biochemical warriors, or 100 robots, and more than 1,100 large and small spaceships are two or three million cyborgs, or nearly a million robots, and this expenditure is terrifying.

The reason why the number of biochemical warriors is four or five times that of robots is because of the limited control of the central intelligent brain.

Bio-Warriors, also known as Clone Warriors, are more autonomous than robots and can be manipulated using simple commands. Robots need to be controlled by the central intelligent brain in all aspects in order to exert the strongest combat effectiveness, so the number of robots is much smaller.

However, cyborgs also have their own shortcomings, because of genes, the lifespan of biocyborgs is generally not high, usually around twenty or thirty years, and over time, cyborgs' own genes will collapse, which is also a problem that cyborgs can't avoid.

Robots do not have this aspect, and robots are usually in a dormant standby state, which is only activated when in use, and can last for hundreds of years, which is much more cost-effective than BioWarriors.

Is it really hard to judge who is superior or inferior between biochemical warriors and robots?

"It's all standard, does Your Highness prefer to use Biochemical Warriors or Robot Combat Corps?"

Lu Tianyu was speechless for a moment, obviously the Central Intelligence Brain understood his meaning wrongly, but this is also normal, out of rejection of cyborgs, he thought for a while and said: "It's better to be a robot, by the way, can you add human skin and muscles to the outside of the robot, and it looks like a normal human on the outside?" ”

"Your Highness is talking about humanoid war puppets, of course there is no problem with this, but the skin and muscles attached to the robot can be maintained for up to ten years before aging, and after ten years, it needs to be re-implanted, and the price will be more than doubled, if Your Highness doesn't need much, there is no problem!"

"The island needs to be guarded, and I need someone to protect me, so let's make a hundred humanoid war puppets first, half male and half female! When will it be built? ”

"It will take half a year."

Lu Tianyu's consideration is a little different from the Central Wisdom Brain, there is no human figure on this small island for a long time, and there is no guarantee that there will be a blind guy who will quietly land on the island, what should I do if I find the secret on the island at that time, will I kill them all?

There are also parents and pleasure around them who also need to be protected at all times, Lu Tianyu is very worried that the guy who doesn't open his eyes will do these things, at that time, he was not only very passive, but also the taste of being coerced was not comfortable.

It is necessary to take precautions and prepare a little early.

Of course, Lu Tianyu is not worried that these humanoid war puppets will be discovered, human beings are now quite developed in robot technology, there are a large number of simulated robots to serve human beings, and the technical level is naturally inferior to the Martian civilization, but the appearance is very close to ordinary people, and as long as the humanoid war puppets are not sent to the laboratory for analysis, they are similar to the simulated robots made by humans just from the outside.

Lu Tianyu stretched out his hand to stroke the World Tree seedling, and dropped a drop of bright red blood on the leaf of the World Tree, and the blood droplet seemed to stick to the emerald green leaf all at once, and the blood threads extended along the veins of the leaf, and soon the blood droplet merged into the leaf.

"What's next?"

"It depends on the affinity between His Highness's genes and the World Tree seedlings, but now, the World Tree Seedlings do not reject His Highness's genes, and when the World Tree Seedlings grow to the first stage and have a weak sense of self, His Highness can try to communicate with the World Tree, if it is the World Tree Seedlings that have a reaction, even if they initially accept His Highness!"

"I see!"

Lu Tianyu is still the first time to know that the World Tree can communicate with the outside world, but it takes a long time, it is said that the ancestor of the Martian civilization resonated with the World Tree, thus getting many benefits, and some people even said that the soul of the ancestor of the Martian civilization did not disappear after his death, but merged with the World Tree, of course, these are all legends, and the real situation of the royal family is impossible to spread, so no one knows the authenticity.

Of course, if the World Tree seedlings can't really grow into the World Tree, all this is empty talk.

Lu Tianyu didn't take this matter to heart, and the future really couldn't be said clearly!

Lu Tianyu thought of another Martian relic space he had discovered in the Far East, which seemed to be a small war warehouse, the scale was nothing in the eyes of the Martian civilization, but now he could use it.

"I found an arsenal left over from the Martian civilization before, and the weapons in it should be able to be used, but unfortunately I don't have a large storage space now, so I can't carry too many weapons and equipment here, is there any other way to solve this problem?"

"Your Highness, this is not a problem, since Your Highness has already been to that arsenal, you have already left information about Your Highness inside, and you can use a remote quantum teleportation device to transfer the weapons there here! And in the future, if His Highness finds anything good in other remaining spaces, he can also teleport here directly! ”

Lu Tianyu didn't know that there was such a god operation, this is the legendary directional teleportation function!

What makes Lu Tianyu happiest is that he has a sharp weapon in his hand that can quickly shuttle around the country, as long as the coordinate points are input into the quantum directional teleporter, it will almost take a few seconds to go back and forth between the two places, not to mention the speed, and the security and concealment are also nothing to say.

But this kind of transmission also has some drawbacks, such as the same quantum directional transmission equipment must be installed between the two places, the same encoding and decoding program, the number of transmissions at one time can not be too much, the volume is only ten cubic meters, and the distance is also not too far, at most one million kilometers, that is, three light seconds, and there can be no strong interference in the middle, etc., but these drawbacks are not much of a problem for Lu Tianyu now.

"Is that all the Martian ruins have such quantum directional teleportation devices?"

"Quantum directional teleporters are usually set up in these places, but there are some exceptions, such as in imperial cities, such as in large military bases, or in extremely important mineral veins."

The problem of Lu Tianyu wanting to return to Black Reef Island in the future was easily solved, and even in the future, as long as he installed quantum directional teleportation devices in many places where he traveled and went, it would be a blink of an eye to go anywhere, and he couldn't help but start feeling homesick when he thought of this.

However, before going home, Lu Tianyu still decided to go to Amazon first, but before that, he had to make a phone call home to report his mother's safety.

This time, the communication line is controlled by the central intelligent brain, and Lu Tianyu does not have to worry about being monitored.

Inside a mansion in Jinling.

A middle-aged woman handed a glass of juice to a boy who was playing, and said to a slender and beautiful woman reading under a parasol next to her, "Are you still thinking about that kid?" ”

The young woman opened a pair of big jewel-like eyes, supported her chin with her hands, and said worriedly: "Tianyu has not been in touch for six or seven days, and I don't know where he is now, is it really worrying?" ”

The middle-aged woman was Lu Tianyu's mother, Miranda, and said with a smile: "That kid is a clever thief, when he was a child, he hid from the cat, and the other children couldn't find it and went home, and he hid outside and didn't come out, so I searched for a night before I pulled it out of the reeds by the pond and beat him hard?" ”

The young woman is happy, she still clearly remembers what Miranda said, she cried in a hurry, but Lu Tianyu just couldn't hide, and thought that something happened to Lu Tianyu? Frightened the pleasure.

While the two were talking, the communicator on Miranda's wrist vibrate, and when she looked down, she saw that it was an unfamiliar number, and she couldn't even see any information about the other party, and thought it was another sales call from that company, so she hung up without hesitation.

"Auntie, who's calling?"

"I don't know!"

Miranda's mood was also a little bad, but it was not as happy as on her face, but fortunately, Lu Tianyu went to Germany, met his father, and asked Scott to report Miranda's safety, which made Miranda feel a little more at ease.

At this time, the communicator on the wrist of the pleasure also vibrate, and it was also an unfamiliar number with no information, and I didn't want to answer it, but I pressed the answer button by mistake.

Lu Tianyu's voice came from the other end of the phone: "Happy, do you miss me?" Not surprised, not happy! ”

Yue Yue covered his small mouth all of a sudden, and he couldn't speak excitedly, but when he looked up and saw Miranda's inquiring eyes, he hurriedly said, "It's a call from Tianyu." ”

"Give it to me, this stinky boy won't even call me!" Miranda was a little jealous.

"Hey! Stinky boy, you're there, you're happy outside, and now you don't even want your mother! ”

Lu Tianyu was speechless for a moment, and said to the sky: "Didn't you call your old man just now?" If you don't answer, what should I do! ”

"Yo Yo! It's reasonable, don't you want to reason with your mother", Miranda finally showed a little smile, but still had to be unforgiving: "Stinky boy, no matter where you are now, give you three days to come to Jinling, I have something to tell you!" ”

Lu Tianyu had a headache for a while, and said helplessly: "Mom, I have something to do now, can I wait for ten days to talk about it?" ”

"Can't!"

Miranda said dissatisfiedly into the communicator: "If you don't come back immediately, I'll go to you with pleasure, this matter is not negotiable, do you hear?" ”

"Good, good!"

Lu Tianyu immediately surrendered: "Okay! It's good that your old man is happy! ”

Miranda launched a rush that even his father had to retreat, as a son, he didn't dare to make his mother angry at anything, but his plan was disrupted by his mother.

"This kid is getting more and more disobedient!" Miranda hung up the phone decisively, not giving Lu Tianyu the slightest chance to excuse himself, and said in a soothing tone: "When this kid comes back, you will marry him, and it's time to take care of your temperament!" ”

Pleasant and pretty, her face was slightly red, and she hurriedly lowered her head without making any answer, but her heart was sweet.

After Lu Tianyu was chased and killed by the mercenary group and was known by Miranda, Miranda felt more and more that Lu Tianyu was playing a little crazy, and he didn't tell his family about such a big disaster, and he should find someone to restrain him, so he talked about it with her husband.

When this matter is said to the happy parents, there is naturally no reason to object, and I also hope that the two will get married and have children as soon as possible, so that the old man will have to worry all day long.

However, the current situation is a bit special, if the marriage is done in Antekan, God knows if the mercenary group will jump out and cause trouble, so Miranda brought the pleasure to Jinling, preparing to let the two get married quietly in Jinling, and then go back to Antekan to hold a banquet after the matter subsides.

It's a matter of getting on the bus first and buying a ticket later!

But Lu Tianyu on the other end of the communicator was depressed, and after thinking about it for a long time, he didn't understand why the old lady wanted to go back to Jinling by herself, and she seemed to be in a hurry, for fear that the old lady would do something to her.

However, why did Miranda appear in Jinling, Lu Tianyu was not surprised, he quietly checked his mother's family background, and found that his mother's family was not simple, and it turned out to be the Mi family, one of the eight major families in Huaguo.

This is easy to explain why my mother usually doesn't mention family matters in front of Lu Tianyu, there are secrets that Lu Tianyu doesn't know, but I am very curious, my father is just a person with a fairly ordinary background, and he was able to marry Bai Fumei, and the heart of gossip was ignited, but these are all things between fathers, and Lu Tianyu didn't want to ask more, so as not to cause his mother's unhappiness.

But why did my mother appear in Jinling at this time, did she want to take herself back to her mother's house to see, but then she denied this idea, and she didn't take herself back for more than 20 years, what did she do when she went back at this time?

Lu Tianyu quickly roughly guessed his mother's intentions, he caused such a big thing, if there was no support from the big forces behind him, it was certain that he would be hiding everywhere, his mother was planning for her future, thinking of this, she couldn't help but feel hot, family affection is always selfless.
