In the following days, in addition to practicing, Ma Yan followed Yang Yifei to study mathematics, physics, and chemistry, and Ma Yan finally realized the fear of being dominated by mathematics, physics and chemistry.

But he is the only one here, Yang Yifei is one-on-one teaching, there is nothing to distract him, and he was brainwashed by Yang Yifei's "learn mathematics, physics and chemistry well, and he is not afraid to go all over the world", so he learned very hard and quickly.

The development of the Perfect T virus in his brain has also gradually manifested itself, and in just two months, he has learned mathematics from the first grade of primary school to the first year of junior high school.

He didn't need to take any exams, so Yang Yifei did not use the test-oriented education for his teaching, but paid more attention to practice and application, so he didn't experience the pain of the sea of questions.

Now he has also evolved telekinesis, and under Yang Yifei's teaching, he has learned how to use telekinesis, and he can fly on his own, but the speed is not fast and the flight duration is not long.

Being able to fly, in Ma Yan's opinion, this is a sign of truly becoming a cultivator, although it is not strong now, but he believes that as long as he dedicates himself to cultivating with his eldest brother, he will slowly become stronger, and his enthusiasm for cultivation can't help but rise.

He was fascinated by absorbing all the knowledge taught by Yang Yifei, and his daily schedule was full, and his life was extremely fulfilling, in one sentence, he was so busy that he didn't even have time to take a plane.

In addition to knowledge and telekinesis, he did not fall behind in martial arts, after following Yang Yifei to learn martial arts for two months, Yang Yifei gritted his teeth and bought a tracker bare machine to come out as Ma Yan's sparring partner.

When he saw the tracker for the first time, Ma Yan was frightened by its hideous appearance, so Yang Yifei put on an iron mask that only showed his eyes, which was much better.

The tracker can not only be used as Ma Yan's sparring partner, but also as a good laborer, at first Ma Yan didn't dare to order the tracker, but after Yang Yifei told him that this was just a puppet magic weapon, he was relieved.

……

Three months have passed in a blink of an eye, and on this day, Yang Yifei was giving Ma Yan a chemistry lesson, and the prompt sound in his mind that the experience was about to start suddenly sounded.

Yang Yifei said to Ma Yan: "You think about it yourself first, and go to the laboratory to do experiments!" I'll go to a hut. ”

"Oh, good." Ma Yan didn't think much about it, just now Yang Yifei taught him the decomposition of potassium permanganate to produce oxygen, he has almost mastered it, you can do an experiment and try it.

There are perfect experimental equipment and materials in the laboratory, and he only needs to use his hands, while Yang Yifei walked out of the room that was used as a classroom, and with a wave of his hand, he put away the tracker standing outside the door and entered the bathroom.

He knew that no matter how long it had been in the training world, only a few minutes would have passed in the Overworld, which was exactly the time of the last hut.

Yang Yifei locked the bathroom door, closed his eyes, and after a few seconds, his figure disappeared into the bathroom.

……

The peaks are tall and tall, and the walls are like sharpening.

The location where Yang Yifei appeared this time was a mountain with extremely steep terrain, and at this time he was still dressed in a leather coat and land combat boots, and there was nothing wrong with this outfit no matter whether he was in ancient and modern times.

In ancient times, this should have been a kind of night suit or power suit, but in modern times it is even less problematic.

Yang Yifei flew up slightly to a certain height, and after observing the surrounding terrain, there was a look of understanding in his eyes.

Not surprisingly, this should be Huashan, and when he was still alive, he traveled to Huashan once during his vacation to remember the overall topography here.

As a special forces, remembering the terrain where you have been is both basic and instinctive.

According to past experience, in general, near the place where he appeared, there are most likely situations that can make him cut into the plot, so he didn't choose to fly away directly, but planned to walk around the neighborhood first to figure out which world this is.

Otherwise, if you fly away blindly, you may miss a lot of plots, resulting in missing some plot changes, and as he progresses the number of times he has experienced, the basic score of the experience world is getting bigger and bigger, and even if the degree of change is less than 1%, it will be a great loss.

Yang Yifei walked in the direction of the slightly easier road, and when he didn't walk long, he suddenly heard two voices not far ahead, but because the terrain on the mountainside had a curvature, he didn't see anyone.

"Huashan is my Taoist spiritual land, and these twelve big dragon vines are said to have been planted by the ancestor of Mr. Xiyi." This is a clear male voice, and the voice should be a middle-aged man.

Another slightly younger, but more deep voice said, "Ancestor Chen? Is that the immortal who hasn't woken up after years of sleep? ”

The clear voice said: "Exactly, Chen Tuan's ancestor was born in the late Tang Dynasty, experienced the five dynasties of the Liang, Tang, Jin, and Han dynasties, and every time he heard that he changed his dynasty and changed his surname, he was always unhappy and lay down behind closed doors. ”

"It is rumored in the world that he has slept for many years, but in fact, he is just worried about the chaos in the world and the suffering of the people, and he does not want to go out."

"When he heard that Song Taizu had ascended the throne, he laughed and fell off the donkey's back with joy, saying that the world has been peaceful since then, Song Taizu is benevolent and loves the people, and the people of the world have indeed gained a lot of benefits from him."

The deep voice sighed: "If Ancestor Chen Shu was born today, he would inevitably have to sleep behind closed doors for many years. ”

The clear voice sighed and said: "Mongolia rose to the north and deliberately invaded the south, and my great Song monarchs and ministers were mediocre, and I saw that the world was no longer possible, but my generation of men, knowing that it was impossible to do it, should also do it." ”

Hearing this conversation, Yang Yifei naturally understood that it was now at the end of the Southern Song Dynasty, and Mongolia had risen to destroy the Jin State and was preparing to invade the Great Song Dynasty in the south.

Now that the world background has been determined, it will be easy to do, Yang Yifei immediately entered the system mall, and entered the keyword "Song Dynasty Hanfu" in the search box of the mall in the biochemical world.

Naturally, there are no Song Dynasty clothes to sell in the Luding world, only in modern society, no matter what dynasty clothes can basically be bought.

Soon, all the related goods were listed, and the prices were very cheap, all of them were a set of 1 point.

Now that Yang Yifei is fighting, he rarely fights with people in close combat, so he doesn't need to care about the choice of clothing.

After selection, he bought two of them, one was a white gown, one was white, well, all white, nothing else, just because the white clothes looked handsome and sassy enough.

But Yang Yifei has the capital of Sao Bao, he is already long and jade, handsome and extraordinary, coupled with a good skill, at this moment he has completely become a peerless heroic template.

Quickly changed into a white shirt, tied his belt, tied his long hair in a bun with a white ribbon on the top of his head, thought about it, and took out a bronze long sword of the Qin Dynasty on his back.

In fact, the main reason is that the bronze sword body is relatively wide, and it can stand more easily when stepping on it.
