Ever since he had promised the three old men, Leon felt that he could not wake up, and the dream was so lingering, because everything he saw and heard afterwards was so unexpected and unbelievable. Unlike the history shown to him by the brain, all the past of mankind is divided into two clues, one wrapped in the outside and reasonable, and the other obscure and complicated, unbelievable.

History is full of deceptions, almost thousands of years ago, the apostles of the Eye of God began to intervene and quietly influence the path of human development, from the glory of the Nile to the rise of Asia, from the female emperor who broke through the feudal patriarchy to the scientist who was inspired by the apple smash, from the elegant tyrant Napoleon to the butcher of literature and art Hitler...... The whole history of mankind is full of surprises, and under the surface of these seemingly reasonable surprises, there are turbulent undercurrents, and every bit hides countless secrets and conspiracies.

The Eye of God watched quietly, and with a slight movement of his finger from time to time, he quietly changed some of the small details of the grand line, and no one noticed the dusty past, but after a certain period of time, these changed lines often became the key point of life and death.

Leon struggled to understand and learn the deep meaning of these contexts, events that contained the wisdom of countless predecessors, as well as the blood and tears.

While receiving this "history education", he also had to do more adaptive learning, and the place he was about to return to was not full of thick alkane energy or high-density metals, everything was very primitive, primitive to the point of headache.

At the moment, Leon was dealing with a mess of copper wire, known as the "Computer", a stupid tin case filled with all sorts of components and messy copper wire, and very excessively, the thing had been scorched. Leon needed to restore the main part of this thing in twenty minutes, and find a copy of the information inside, about which he had spent no less than five hours studying, which was very excessive for Leon, who had learned to make twenty bombs in 30 minutes.

"Can anyone tell me who invented this bite-bite, broken apple?Why display images in such a stupid way?...... hell" Leon's fingertips tensed slightly, and the block keyboard shattered into powder, and he looked at the pile of ghostly flashing commands, and almost wanted to smash the box called the screen in front of him.

"Don't look down on this thing, its appearance has pushed the development of human science and technology forward a lot, and all fields have been helped by this broken apple, do you think that memory metal or three-dimensional projection ball has been there since then?" Huang Zifang shook his head as he said, he rarely made such superfluous movements or exaggerated expressions, but in the face of this ancient box printed with colorful striped apples, his unprecedented expression was enriched," This is the initial prototype of the world's first personal computer, and the next hundreds of models will gradually become more simple and intuitive, and it will take me a lot of effort to get these things, don't waste my mind, in the place where you are going, everyone will use a computer, and you, what you need to do is to be proficient"

A few hours later, Leon was sitting in a simulator, bored with the buttons around him, he felt that these things operated in the same way and in the same way, there was no need to rehearse each of them, and now he was facing an ancient fighter called the A-37, and the thrilling reality simulation did not interest him in the slightest.

Bishop San Juan was standing outside the simulator and humming, the remote control device in his hand kept changing, he had just piloted the U-2 transport plane, and it had been less than 5 minutes since he switched to the fighter plane.

"Okay, stop" Huang Zifang patted San Juan's shoulder sympathetically, "I have changed more than 170 kinds of driving equipment, including those that go to the sky and enter the sea, and the span has long exceeded 40 years, you should also understand, these things can't stop him, with his strong physique and mind, it is estimated that it will not be too much of a problem to throw it directly on the shuttle, let alone those things of the old times"

San Juan had a calm face, and angrily stuffed the remote control into Huang Zifang's hand, turned around and left, and said to the built-in communicator at the same time:

"Follow me to the gun room, there's no rest for today"

In the evening, it was the hardest part of the training, and Hugh Grant always found pleasure in this time period, watching Leon frown in the face of those ancient words, he would leisurely brew a cup of vanilla tea, quietly appreciating, and he was a little proud that he could embarrass this genius-like guy.

Hugh Grant is in charge of the language part, of course, not simply teaching Leon to learn reading and pronunciation, but to understand the cultural connotation of hundreds of years ago, and even more difficult is cryptography, including decipherment and production, covering nearly a hundred years of cipher sequences, which are complex and boring.

However, Hugh Grant's fun lasted for three days, and on the evening of the fourth day, he was stumped by the first password designed by Leon, which was a set of text messages in the format of Tang poems in ancient Chinese, and after 30 minutes, Hugh Grant threw the pile of square words next to the teacup in frustration.

"Tell me what this thing is? Hide your head, piggyback, sound trains, I've tried it all, it's not written at all!"

Leon looked at Hugh Grant's tangled face with a grin, shrugged his shoulders and said:

"It's the Chinese character code made with Russian pronunciation, and it's you who told me to think outside the box and look at the whole world"

Hugh Grant picked up the memory in disbelief, began to reinterpret it again, and after a while, he looked up angrily and shouted:

"You actually put mandala alkali in my teacup!"

"If you had just decoded it, you wouldn't have drunk it," Leon replied with a hippie smile, and then looked at Hugh Grant's face with a foolish smile and his face began to flush.

Leon pretended to be relieved:

"At least you'll get a good night's sleep tonight"

On the morning of the fifth day, Leon sat down in the pharmacy early, as usual, this part is what he is most interested in, all kinds of hallucinogens and paralyzing drugs, chemical agents that can make the body stiffen or various physiological illusions, from subtle recipe changes to control the subtle effects of drugs, fine manipulation and matching inspiration, mysterious, Leon even thought that if he was born in the old times, maybe he would become a doctor.

On this day, however, the three bishops appeared together in the large room full of bottles and jars, followed by four monks, each pushing four hoverboards, on which four corpses lay flat.

Huang Zifang's face was as calm as ever, he pointed sideways to the display wall behind him and said:

"There is nothing we can teach you anymore, starting today, you will learn the most important lesson, which is basic biology, and there will be two very good teachers to teach you, you are all old acquaintances, I believe this learning process will be very enjoyable"

Leon watched as two familiar faces appeared on the display wall, two fat old men, Smith and Ptolemy.

The two fat people have their own styles, but at this moment, whether it is the slightly majestic Smith or the somewhat funny Ptolemy, they all have serious faces, even angry, Leon looked at them with tears and laughter, wondering in his heart whether the Bishop knew that these were two old rivals, and they were teaching together, I was afraid that they would drive the students crazy.

Then, the scene that made Leon even more devastating continued, and the black forehead and the firebird, who had not been seen for several days, also appeared in the small pharmacy,

"From now on, you'll be trained in biology together," Hugh Grant said very seriously, "and in three days the Archbishopric will be in Uptown, and you'll need to figure out how to get through their observations during those three days."

"Let me fight hard, and I want them to agree?" Leon pouted disdainfully, "When I'm a slut"

"If you want to go back, you have to be prepared for this, their old-fashioned and conceited are probably unimaginable, the archbishops are old monsters who have lived too long, each with a strange temper, but we have our goal, it's a deal between us, isn't it?"

"Deal, good, I like that word" Leon shrugged his shoulders indifferently, "If enduring the harassment of the Archbishopric is also part of the deal, then I have to attach one more condition"

The three old men glanced at each other, and they all saw the helplessness in each other's eyes,

"What conditions?" asked Hugh Grant in a low voice,

"Take care of some people for me," Leon's expression became serious, "those of my buddies, they're still fighting those nuclear storms and mutant beasts in the wilderness, and to put it mildly, I agreed to enter the time stream to be a bullshit golden apostle, just for them"

San Juan had in his mind the information he had, and the faces of the boys and girls appeared one by one,

"No problem" he felt a little relaxed, it was only a dozen or so people,

"Don't be so easy to promise, I'm talking about the 20,000 C-Crows of the Monolith," Leon said, looking at the three bishops, "You owe them too much, I'm just giving you sinners who believe in gods a chance to redeem yourself."

Ten minutes later, the three bishops left the apothecary room with gloomy faces, which had been adjusted to become a medical laboratory with advanced equipment, while Leon and Blackforehead, along with Firebird, had already begun their first lesson in biology, human anatomy.

"He wants too much" San Juan couldn't help but be the first to grumble, the footsteps of three people echoing in the empty passageway,

"The more he wants, the easier it will be for us to control him," Hugh Grant replied leisurely, "Bonds are the best motivator, and now that we finally know his weakness, it's good" A strange smile appeared on the bishop's blade face, like an old cat holding down the tail of a mouse.

At the same time, the two fat old men in the laboratory were also smiling at each other,

"That's it, make a final decision with these three little ones?" said Ptolemy, fiddling with a laser cutter in his hand.

"Yes, but don't regret it, as far as I know, they're all murderous guys, and I know a lot more about them than you do," Smith replied proudly, and Ptolemy froze when he heard this, and then smiled whimsily,

"Hmph, since you said so, of course I'll pick people first, otherwise it's too unfair"

"Take your pick!" in three days, let's see whose student is better," Smith glared at each other viciously, and the gaze of the two men could almost wipe out a spark.
