Jing Lei raised his head and saw the clear and transparent water slowly flowing above his head, this river had no channel, and listened to Biluo tell her that the reason why the river flows honestly in the air is because there is something called "force field" that restricts them. And this invisible and untouchable force field is generated by those stone slabs engraved with runes.

"It's really Tianhe!"

The girl couldn't help but sigh in her heart.

Not only her, but many villagers also have the same idea in their hearts. The people present all looked at this heavenly river blankly, no one exclaimed or talked, under the clear sky of autumn, the crystal heavenly river slowly flowed overhead, and the shock brought to them by this scene can not be described in words.

The human worldview is a wonderful thing, it may not change for a lifetime, or it may be suddenly changed at a certain moment.

It is the latter situation that occurs at this time. These villagers, who have lived on the land all their lives, suddenly discovered at this moment that some things that were originally very ordinary would become so wonderful once they were put into the sky!

The conquest of the sky is an instinct rooted in the genes of every human being, and it is precisely because of this that ancient humans fantasized about becoming birds and immortals rising into the sky, and it is precisely because of this that modern humans invented airplanes and rockets.

And at this moment, the conquest of the sky has become the dream of every Biluo villager, and this idea is so deeply rooted that in the theocratic society in the future, the pursuit of the sky has become the common tendency of the whole society, and therefore, the appearance and style of the kingdom of God are finally completely beyond Fei Cai's imagination.

Of course, this effect will not be felt until much later, but there is another effect, and the effect occurs immediately.

There was a sound of footsteps around him, and Fei Cai turned his head and found that Qing Lei had come and walked in front of him.

"What's the matter?"

The girl looked like she wanted to say something, biting her lip and hesitating for a while, but she didn't say a word.

Fei Cai implemented the principle of "if the enemy does not move, I will not move", and he was not in a hurry to ask, and waited patiently for her to speak.

“......”

After a long time, Qing Lei finally made up her mind and spit out four words: "Teach me an oracle!"

"Huh?" Fei Cai showed an unexplained expression.

"Didn't you say that you knew the oracle? I heard Biluo say that this heavenly river was created by oracles, and it seems that there were no cruel means such as living sacrifices...... So I think what you said about the oracle...... Seems to have some merit...... So can you teach me ...... too?"

By the time the girl finished speaking intermittently, her pretty face was already a little red, after all, not long ago, she thought that Fei Cai was just a liar with stronger magical powers.

Fei Cai finally understood what she meant, and why she was so hesitant, and couldn't help but show a smile on her face.

When Qinglei saw his expression, her face immediately turned even redder, and she said loudly: "You, don't get me wrong...... I—I didn't let you teach me because I believed in you......"

"Poof......

As soon as he heard this, Fei Cai finally couldn't help laughing, and he couldn't help but complain wildly in his heart.

You're just a textbook tsundere line, isn't it? Am I in an RB light novel? Is the title of the book "My Witch Can't Be So Cute"?

After laughing for a while, seeing that the girl's whole person seemed to be about to explode, Fei Cai quickly held back his laughter and said seriously: "Okay, then go to the stone building to find me and start the first class!"

"Huh...... Good. The girl didn't expect him to agree so quickly, she was stunned for a moment, quickly agreed, and then turned and ran away.

......

The smooth operation of the pilot line of Tianhe Phase 1 represents a good start, but the really arduous project is yet to come.

Fortunately, the selection of wizards went more smoothly than expected.

Qinglei and the elders had already spread the teachings, especially the eighty villagers in the construction team, and because of the "cultural courses" carried out by Qinglei in the team, these people had already memorized a few oracles by heart, even if they did not understand them.

After learning that the wizard could participate in the construction of Tianhe, everyone immediately flocked to Yanli and asked to become his disciple.

Due to the fact that the number of people was far larger than expected, Fei Cai had no choice but to design a simple test paper, which mainly tested the candidates' understanding of the four oracles, and set up some simple logical questions to test the candidates' logical thinking ability.

In this way, the "First Wizard Apprentice Selection Examination" began in the open space next to the altar, and since most of the villagers could not read or write, the examination was mainly in the form of oral questions and answers. There are three examiners, namely Fei Cai, Biluo and Yanli, and the candidates are divided into three groups by drawing lots, of which the candidates in Group A are interviewed by Fei Cai, Group B Biluo, and Group C is Yanli.

Although the questions in the three groups are the same, and the scoring criteria are exactly the same, due to Fei Cai's special status as a divine messenger, most of the candidates who accept his questions are extremely nervous, so Group A unfortunately became the "Group of Death", and in the end, only one candidate passed the selection.

On the contrary, there are four in Group B and five in Group C, which makes Fei Cai cry and laugh.

Soon after, everyone was busy again.

During this time, Yan Li's main focus was on the training of ten wizard apprentices, and the next Tianhe project was much larger, with a preliminary estimate of as many as a thousand runes to be engraved. If these ten apprentices can be trained, even if they are not so skilled, it will be a carbon send-off for the construction of the entire project.

Biluo began the design of the force field structure of the entire Tianhe Phase I project. The first phase of the Tianhe River is conceived as a network of rivers suspended in the air, which will be exponentially more difficult to design than the pilot project's mere river. Fortunately, Biluo's mathematical skills are extremely solid, and the design is progressing in an orderly manner as planned.

In addition to helping Biluo solve a difficult problem in design, Fei Cai's other main job is to teach Qinglei. During this time, after Qinglei trained the construction team every day, she came to him to learn the oracle.

The content of his teaching to Qinglei is different from that of Biluo, and from the very beginning, he has designed the final direction for the other party: electrodynamics, or "electromagnetism" in layman's terms.

"Biluo's ability comes from the oracle of Newton, the great witch god, and your ability comes from the oracle of another great witch god, his name is Maxwell, and his oracle is called 'Maxwell's oracle', which is composed of four 'divine equations' (mathematical equations), and the meaning of these four divine equations is too difficult for you to understand. You just need to know that everything I'm going to learn from now on is to make you understand these four divine law equations. ”

Fei Cai began the whole course with such a paragraph.

"What, to understand this, what 'Maxwell's oracle' is so troublesome?" Qinglei couldn't help but complain when she heard this.

"Why? are you scared? But I can understand it, after all, it takes a lot of hard work to understand Maxwell's oracle before that. Fei Cai said deliberately.

When the girl heard this, she was really tricked: "Who is afraid! Hurry up and give a lecture, big liar!"

Looking at the other party's unconvinced expression, Fei Cai secretly laughed in his heart and said, "Then I'll start." Lesson 1, Four Operations......"

The busy but fulfilling days are passing day by day, the weather is getting cooler and cooler, the winter in southern Xinjiang is much better than in the north, and the villagers are doing what they should do every day, and they are not nervous because winter is approaching.

Fei Cai's first New Year after coming to this mission world is approaching.
