Five days later, the Earth World.

Putting her hand around her bangs in front of the mirror and finding that her hairline seemed to have moved up again, Kelly sighed a little worriedly.

It was much more difficult to make a train from scratch than he imagined, and the existing rail carriage in the Holy Soul Continent world, except for the shell that could be used, everything else needed to be tinkered with by himself.

Although he studied a related major at the beginning, he did not engage in this work after graduation.

Even if he did, no one taught him how to make the original version of the steam engine...... Yes, the original version, at first he really wanted to make a modern train in one step, but he gave up on this idea in a few days, the tech tree, it had to be done step by step. Even the most primitive steam engine, there are many materials that the Holy Soul Continent does not need, and he needs to make it up little by little.

Taking notes, reading books, checking information on the Internet, and doing various experiments in the Holy Soul Continent every day, Kelly felt that she was working harder than when she was admitted to graduate school.

Especially in the past few days, Xia Yi has frequently run to his workshop, and even threw him a six-star mink demon as an assistant, letting him call him at will, which made him unconsciously bear huge pressure.

"Another day of little progress."

After washing her face and sobering up, Kelly sat back at her desk, ready to continue chewing on the college textbook, when she found that the screen of her mobile phone on the table lit up.

Exchange group, there are people Aite all.

[Management] [Duoer]: 'After half a month of training in my GZ48 girl group, it is about to perform for the first time, and the time of the performance is set for five days later, and the location of the first performance will naturally be selected in Lieyang City.

[Diao Kou]: 'So fast? ’

[Qiu Chan]: 'B-rank players who can't participate express envy (crying face)'

[Seven Sages]: "It's a bit fast, but the appearance is there, it looks good at will, Uncle is looking forward to it, wear less (bad laugh)'

[Hou Chou]: 'Must go!' ’

[Ran Elf]: "Hehe, let's just wait and see, the goddess is far-sighted, after the official establishment of the women's group, we are all branded with the three-star exclusive Holy Soul GZ48 women's group, practicing singing and dancing fast, one day is stronger than six days......

[Seven Sages]: '? 666, then Uncle is looking forward to it even more. ’

"One day is stronger than six days, how much does Nanfu battery give you?" Smiling, as a 27-year-old single dog, Kelly also has some expectations.

At this moment, he suddenly sighed softly, a flash of inspiration flashed in his mind, and he re-read this chat message, and the big bald brain seemed to flash the luster of wisdom!

"The Holy Soul of the GZ48 girl group is stronger than six days in one day of practice...... Holy Soul! ”

The next day, when Xia Yi went to Kelly's workshop to see if he had any problems that he needed to solve by himself, he found that Kelly had left behind the prototype of the big steam engine that was problematic no matter how much he saved, and instead tinkered with a small copper foil and some steel wires and copper wires.

Glancing at the baby mink, the baby mink, whose face was sticking to a lot of soot, jumped on Xia Yi's shoulder, and whispered: "This guy seems to be a little demonic, he suddenly got up at midnight last night and laughed, and then he has been busy until now." ”

Xia Yi sighed softly, carefully observing what Kelly was tinkering with for a moment, thoughtfully.

About ten minutes later, a simple needle was used to fill a small hole in the foil-shaped object with the wire twisted in her hand, and she smiled excitedly when she noticed that the water was flowing as expected.

At this time, he found out about Xia Yi's arrival, and hurriedly greeted: "Senior, there are results, there are results!" ”

Xia Yi: "Let me see." ”

Kelly nodded repeatedly, went to fetch a basin of water, and floated the foil-shaped object on the water.

Then take half of the candle, put it on the foil-shaped object, ignite the candle lead, and in an instant, the foil-shaped object rotates at high speed on the water surface of the basin like a small electric motor!

At the same time, a wave of Holy Soul power came out of Kai Li's body, and his level instantly increased by five or six levels!

[You have explored the four-star Holy Soul: Father of Steam, the current exploration degree is 10%]

The subtitles flashed, Xia Yi's eyes lit up, and he looked at Kelly approvingly: "I have ideas." ”

【Ding! Xia Yi's friendship +10]

[Current Opinion 20 (Friendly)]

Kelly smiled proudly, set her eyes on the prototype of the big steam engine, and for a while, she felt that most of the problems that had caused her headache were solved in an instant!

This is the inspiration he got from the holy soul of Zhang Duo's children's group! It is not possible to directly make a large steam engine that can pull the train car, so why don't I make a small and simple one?

He had already made a simple steam engine on a college campus, and it was not the same thing as a serious steam engine, but it could help him imprint the Holy Soul.

As soon as the Holy Soul of the Father of Steam is imprinted, many problems will be solved!

"It's just such a simple toy, it can brand a four-star holy soul, and if you make this big steam engine, it will definitely be able to rise to five stars, and then improve it, at least six stars, I will be able to make a seven-star holy soul?"

Kelly was more motivated for a moment, and quickly threw the toy improvised steam engine aside.

Take the next step.

"You don't have to be polite to it, you can ask it to do physical work or anything." Xia Yi touched the bald head of the baby mink and said.

"Yes, Senpai!"

The mink baby deflated the mink face, and it didn't dare to argue when it made a mistake some time ago, for fear that all the skin would be stripped off, so it started honestly.

Leaving Kelly's workshop, Xia Yi was in a very good mood. Kelly's method is good, so it seems that the day when the first steam engine in the Holy Soul Continent will be born is not far away, and after that, the train is also not far away.

And the Holy Soul of the Father of Steam should be very powerful, and it will probably not be worse than the Orbital Disease when it reaches the sixth star, and if you get any turbocharged steam engine, you may really have a chance to be promoted to the seventh star.

Is it called turbocharging? Xia Yi was a little unsure, he was very lacking in this knowledge before he crossed over, and he had forgotten it all after so many years after crossing, otherwise the steam engine would have been born eight hundred years ago.

He wouldn't envy Kelly's Steaming Father Holy Soul, this was Kelly's chance, not to mention that he wanted to, and he could also explore synthesis.

The player's is his.

What's his, it's still his.

"There's no need to go to Kelly's workshop every day to worry, there should be good news in a few days, calculate the time, the news from the north should also come over, right?"

Sure enough, at noon, Feng Sanzhi, who lived next door, came to the compound of Xia Yi's house to inquire and sent a letter from his uncle Feng Jiukang.

But the content of the letter was somewhat beyond Xia Yi's expectations...... I heard that there were traces of the Xia family's heirs in Lieyang City, and there was even a king who 'claimed' Xia Yi, the ancestor of the Xia family, and the patriarchs of the Shen family and the Ren family really wanted to come over to investigate.

But it didn't come.

King Jin, who was seriously injured by the Pig Demon God, was injured and directly killed the Shen family and the Ren family, and forced the patriarchs of these two clans to be his secret guards, including Feng Jiukang, who was also ready to ambush the Pig Demon God!

The three patriarchs didn't come to Xia Yi, but they almost wanted to try to join forces to kill the Jin King!

There is only one Yin family left outside the Wei family, because it is in the Great Jin Dynasty, it is very far away, and there is no reply.

Xia Yi was silent for a while after reading the letter.

"It's not a simple reckless man, the lesser of two evils, he knows in his heart that he is in danger of dying at the hands of the pig demon god."

This was a bit of a disruption to his plan to deal with these three first, and then deal with the four Wei families when the Seven Stars of Orbital Disease were there, but Xia Yi didn't care too much, and it was good to be able to concentrate more on the research and development of the train.

It was almost evening, and someone came to look for Xia Yi again, this time it was the right time, and he said excitedly: "I found the old man, I found the yard!" ”
