Jiaoxi's face was a little embarrassed, but he still tried to keep a smile as much as he could.

Most of the students below have prominent family backgrounds, and he can't afford to mess with a small teaching.

However, this is a classroom, and as a teacher, he has a natural sense of honor for lecturing.

Therefore, he still continued to speak, which was exactly in line with the wishes of Chen Kaiyu, who listened to it with relish.

"Source skills are created by talented sources. In today's era, the most mainstream source techniques are inherited from the hands of their ancestors, and few are self-created. At the same time, each source skill is incomparably precious. The middle-aged teacher continued to preach.

But there were not many students who listened carefully.

As the dull bell rang, the teacher left in a hurry, and Chen Kaiyu looked at his back and immediately followed.

"Teach." He stopped the middle-aged man from afar.

"What's wrong, what's wrong?" Jiao Xi looked at the people running over and asked.

This middle-aged man knew this usually hard-working boy, and perhaps he was the only listener in his class.

"That...... I would like to ask if you have any books on source energy properties? I would like to borrow it to enrich my knowledge. Chen Kaiyu asked.

Jiao Xi listened and nodded.

"Yes, you can come with me. I have one there, but you're going to have to get it back in seven days. As you know, the school has rules. ”

"Hmm."

Chen Kaiyu nodded heavily, he followed the middle-aged teacher to his office area, and took the ancient book without any twists and turns.

After thanking him, Chen Kaiyu returned to the slum along the road.

On the way, he tucked the books inside his clothes and returned home safely.

Chen Xiaoyue had already boiled the porridge, and after he hurriedly drank it, he opened the yellowed pages of the book with Chen Xiaoyue, who loved to study......

Chen Kaiyu followed the table of contents and found the pages of the source energy attribute classification, and he and Chen Xiaoyue looked at it carefully.

The first thing to introduce is the source energy of the five elements, and after turning those pages, it is to introduce the classification of source energy attributes, but there are only a few pages, and the records are very shallow.

Not as detailed as the description of the Five Elements Source Energy, Chen Kaiyu glanced at it a few times, and his head was a little drowsy when he saw that there were too many kinds of Source Energy, and he shook his head and found that Chen Xiaoyue was still watching seriously.

"My source ball is the kind that has no color, you help me find out, what kind of attribute is this." Chen Kaiyu, who was overwhelmed by the countless fonts and patterns, was fortunate to seek the help of free labor.

"Okay." Chen Xiaoyue replied cheerfully.

She has very little to do at home, just staring at the wall or thinking about the future......

Now, Chen Kaiyu borrowed such a thick book, which was enough for her to entertain for a week. And, that's where her fun lies.

In these turbulent times, books are a precious thing.

Chen Kaiyu, who was fine, looked at the house to see if there was anything missing.

As soon as today's sacrificial day is over, tomorrow will be the leisure period.

The so-called sacrificial day is the last day of work for all the people in the city.

After this day, the whole city will be in a period of leisure, that is, there will be nothing to do, factories will be closed, schools will be closed.

But people don't stop there, they work harder to build their houses, buy supplies all to deal with the coming 'dead period'.

After the 'period of silence', Vientiane was renewed and the weather gradually warmed up.

Chen Kaiyu roughly cleared up in his heart, there were still four days before the 'Dead Silence Period', and the 'Dead Silence Period' lasted for three days at most, so that teaching would let him return the books after seven days.

When the 'dead period' is over, it is a period of full development, and everything returns to normal.

At that time, on the twelfth day after the school opened, Chen Kaiyu would face expensive tuition, which was 1,500 Bai Yuan coins.

If he couldn't afford it, he would be ordered to drop out of school.

Therefore, excluding the three days of the 'dead period', Chen Kaiyu still has fifteen days left.

He had to scrape together 1,500 Baiyuan coins in these fifteen days, and the average was 100 Baiyuan coins per day.

In the past few days, due to his great luck, Chen Kaiyu was able to earn more than 100 Baiyuan coins.

But he knew very well in his heart that a large part of his income came from the handouts of the noble queen.

It was the only thing in his life that he didn't get for nothing, and that kind of thing was really good, but it gave people a sense of extreme unreality......

Chen Kaiyu took a breath, one hundred yuan coins a day, it's really not a small number......

He looked at the room again, his head spinning.

Now, the tuition matter should be put on hold.

The important thing is how to get through the 'dead period', and this point every year is the time when Chen Kaiyu is most worried.

Due to Chen Xiaoyue's physical problems, she has a natural fear of the cold.

When the 'dead period' comes, Chen Kaiyu will put everything that can keep warm by his side, and the two will hug each other and keep each other warm.

Sometimes, when he looked at Chen Xiaoyue's pale and bloodless face and hugged her cold body, he would feel a pang in his heart.

Every time the girl can survive those extremely cold days, it is a one-time life-threatening test, and she is fighting against death.

Luckily, there is fire ore to prepare for this year.

Feeling the warmth coming from the dilapidated stove, Chen Kaiyu's slightly depressed mood slowly eased a little.

However, it was not enough to rely on a furnace of fire ore, and the faint heat it emitted alone was completely unable to resist the cold that seemed to come from the Nine Hells......

Due to the lack of food, the two sold all the shabby thick blankets in the house.

Looking at the bed slats covered with a bit of withered yellow grass, it was absolutely necessary to buy a few blankets.

Chen Kaiyu estimated that when the 'dead period' came, the two separate beds would come together.

Therefore, you need to put two blankets on the bed, and the bottom one needs to be covered with a rough one as thick as possible.

It is estimated that the price should fluctuate between 10 and 20 white source coins in the black market.

You need a softer, more popular red blanket on it.

The Red Blanket is made from the hair of the Red Flame Cat, a low-level alien beast abundant in the Heavenly Wind Wasteland, and is cheap and affordable, and is loved by the untouchables.

The price of the red blanket is estimated at fifty to sixty white coins.

Next, it's time for a quilt.

The price of the most ordinary quilt on the market is more than 100 white coins.

It can only be the most ordinary...... Chen Kaiyu thought in his heart.

Glancing around the house again, the inside of the window screen must be knocked with a layer of wood, preferably covered with some cotton cloth, so that the heat will not leak out.

The planks are very cheap, and you can buy a few pieces for one white source coin.

Chen Kaiyu compared, about five small planks are needed.

Bargain for the blanket you want to put on the plank, from the quilt you bought.

So, it's just one last important thing.

Food.

Yes, food.

The fire earth rice he had purchased was almost exhausted.

In the 'Dead Silence', if there is not enough food, it means that something terrible is about to happen.

Food is the real source of calories in your body, even though the inside of the house is hot, but the organs in your body are not supplied with heat.

It's scary.

Therefore, it is important to buy enough food to safely survive the 'dead period'.

Chen Kaiyu estimated that he would need fifty white source coins.

All of these combined, there is no two hundred white source coins that can't be solved.

Coupled with the tuition fee of 1,500 Baiyuan coins, Chen Kaiyu is still short of nearly 1,700 Baiyuan coins.

That...... What a lot of money to be worth!

If so many source coins are piled up, it is estimated that they will be piled up into a small hill.

Thinking about that scene, Chen Kaiyu felt a little incredible, but ...... He had to do it.

The urgent need now is to earn two hundred Baiyuan coins.

But he didn't have much of a sense of urgency in his heart.

Because, during the leisure period, the hunter's work can be carried out as usual.

Unless the day before the 'Dead Silence' arrives, the Hunter's Hall will not be closed.

Chen Kaiyu took out the instrument in his arms, and every task posted on it almost had a generous reward of hundreds of yuan coins.

As long as he completes one piece, he will not have to worry about the aftermath of the 'Dead Period'......

So, he had to be worthy of the hunter's uniform he was wearing.

has become a hunter and a source, so naturally I want her to live a good life!
