When Leon appeared a kilometer away from the boulder with the deer in love, Nero led five young needle wolves to meet him, and the lead-bone deer finally calmed down a little and stopped in the distance with a cower, while Leon, gratefully embraced Nero.

"Little one, you've changed" Nero seemed to smell in Leon what he loved more, "becoming much like Black Forehead"

"The black-fronted guy, he knows to see my jokes, he's tired of me" Leon panted and communicated with the Wolf King, and he found that the transmission of information with Nero was extremely smooth,

"Why don't you stun it" Nero looked at the leadbone deer in the distance majestically, and seemed to know everything that was happening,

"It carries the most important parts, and it would not be good if it were crushed," said Leon, as he walked with Nero towards the boulder, and the lead-boned deer followed behind him grumblingly, and after walking for a long time, he saw the hazy silhouette of the boulder, and he quickened his pace and ran, for he had seen Lina from a distance.

Well, it feels so good to be home.

The construction of the boulder did not stagnate because of the teenagers wandering around, Gehr and the old guys did really solid work, two large casting machines have been completed, a batch of refined characteristic metals have also been forged, and they are stacked in the queen's tent in different categories, and the space in the tent is divided into several areas in an orderly manner, and at the same time five small buildings of different heights have been built. Many of the megalithic posts had already been delivered, so the planning of the living quarters was basically in place, and even the livestock shed set up next to the tent had been completed, where ten Yan Niu Geng and four lead-boned deer were fed, and the coercion of the needle wolf was isolated from the constant pressure, and those guys at least would not suffer from depression.

However, the construction of the outer wall of the boulder never began, and even the energetic Pyrros had little confidence in building the wall, given the sheer amount of work.

But now that Lyon had returned, everything began to look optimistic, and they brought back not only the enthusiasm and confidence of the young man, but also some good things that Geer had never dreamed of.

The trophies they had brought back were piled up in the corner of the queen's tent, and the strange equipment and equipment attracted Jiao and Picasso to go around twice a day, but the two old men soon discovered that most of the things they couldn't figure out what they were.

As soon as Leon returned to the boulder, he was dragged to the queen's tent by two old men, and Picasso pointed to the pile of things and said excitedly:

"Stinky boy, let us two old fellows wait! you must tell me the same today," the old black man waved his little fist, his white beard trembling violently.

"That's right!" Lao Jiao's small eyes behind the goggles also widened, Leon meditated in his heart, these two old naughty boys didn't know what bet again, they were so excited, but he spread his hands and said helplessly:

"I don't know what to use a lot of things, I can't explain them all until Luo Luo comes back" Then his face changed, and he said with a smile: "However, I know the usefulness of two of them, and it depends on the two of you masters to carefully study and thoroughly understand this technology, this is the secret weapon of the future boulder"

The two old men were immediately elated by these words, and Lao Jiao patted his chest with a proud face and said:

"Just say it!

Leon picked up and dragged out half a robotic arm and a string of curved bends from the mass of things,

"This is the mechanical arm of the war ashes, a lot of their work is done by this big guy, the power is great, the speed is fast, the most important thing is that the operation is precise and will not make mistakes, if it can be mass-produced, it can replace labor, and this ......" Leon unscrewed the elbow from the middle and continued:

"Don't underestimate this rusty barrel-like broken tube, this is a transmitter that can greatly refract distant scenes, its effect is magical, for example, it can be used like this" Leon filled a small energy bubble in the middle of the elbow, pressed the small button on the other side, and saw his body suddenly disappear, "How is it? Isn't it amazing?" Leon's lonely head said in the air, which made the two old men gasp,

"If it's bigger, you can make people invisible!" Lao Jiao immediately thought of this,

"Think about it, what if it was bigger, what if you copied more elbows?" asked Leon, like a good teacher.

"You mean...... Can you hide the whole team?" Lao Jiao couldn't help but scratch his head, this thought made his scalp explode, what a terrible army it would be,

"I'm afraid it's not just the army ......that hides," Picasso smiled, his eyebrows fluttering, "this stinky boy always has a big appetite"

"That's right! I'm going to make the boulder a gathering place where you can hide invisible!"

The day after Leon returned to the boulder, the two old men and Piros entered the stage of frantic calculation and development, the elbow was carefully broken down into more than 200 small parts, they analyzed the principle of the device from all angles, and deduced the feasibility of Leon's crazy idea.

Leon also handed Gehr two other devices, which put Gehr into a painful state of research, which were the outer defense sound waves from the ashes of war, and the same strange smell meter, which made the island of Ember Rock perfectly hidden in the Pacific Ocean for hundreds of years, and Leon believed that the boulder could do this on land.

Lina had long been interested in several mechanical launchers and specialty bullets, and she was pondering the possibility of mass production, since these guns didn't need energy bubbles to be used.

Daigo has given full play to his ability to manipulate the peel, he is now the busiest person in the boulder, and all kinds of calculated data need him to make a final demonstration, but fortunately, the boy has not yet taken the "time potion", and the brain's manipulation ability has made greater progress than before, however, there are not many days like this.

Oolong has already set off for the Chiwu gathering place, and the time agreed with Udai Ye has arrived, and he needs to retrieve the "time medicine" between himself and Daigo, their fingertips are already a little gray, and they can't delay any longer, otherwise they will soon become gray aliens.

Also worrying Leon were the other three guys, Lockdorge, Figama, and Midow. Miduo slipped away quietly with her skewer princess before Leon returned, and she somehow got a test spot, and she didn't even tell Piros to go on her own road, which shows how determined she is. At the moment, the three of them should still be doing the upgrade test somewhere, I don't know what kind of process it is.

Regarding his future, Leon had to rethink, during this time he spent most of his energy on "internal vision", observing the black spiral towers in his body with the black forehead, and trying to find the law of the development of those black cells, but unfortunately, they knew too little about biological knowledge, except for understanding the division law of the black cells, nothing else was found, and what made both of them quite puzzled was that those cells were not exactly the same as the black forehead.

"Is it because the venom of that poisonous jaw mother worm has mixed in?" Leon closed his eyes, "looking" at the strong and active cells, and at the same time communicating with Blackforehead, who also closed his eyes, observing the subtle images that Leon transmitted to him,

"I'm afraid it's more than that," Black Forehead remembered the dirty hematopoietic machine that Piros picked up back that year, "There may be something left in that machine, but unfortunately we will never know what it is"

"I should be thankful for that broken machine, if it weren't for what was left in it, I might have been swallowed up by your black blood a long time ago, or my blood vessels burst and died, hehe" Leon still had his eyes closed, but he couldn't help but turn up the corners of his mouth, "But I'm curious, why don't you use 'nai'?"

"Hmm...... I just thought it would be a very dangerous move, so I naturally avoided that evolutionary direction" Black Forehead hesitated a little for the first time, Leon felt his dazedness, the dazed by his own ignorance,

"Evolution...... Leon also began to think, this is indeed like an evolution, in an unknown direction, but it doesn't seem bad, at least he can get rid of the control of the five-star union.

It's just that Locke Dorjee should they do? Even, what should Show Moore do? Leon reflected the beautiful face of Show Moore in his mind, and suddenly remembered that he didn't even say goodbye to her.
