After nightfall, Chu Tianjiang returned to his home.

After eating something casually, Chu Tianjiang entered the ruins, took some special alloys, and then set out to build a long sword.

"Why do you want to promise her?"

Chu Tianjiang looked back and found that the figure was standing behind him.

"What is your biggest weakness?"

"You said that." Chu Tianjiang smiled bitterly and shook his head.

"You are too soft-hearted and too kind." The figure floated in front of Chu Tianjiang. Because it's just a 3D virtual projection, it can appear anywhere.

"We've talked about that." Chu Tianjiang glanced at the figure and said, "Although the world has changed drastically, I still believe that the reason why people are human is not because they have a human body and appearance, but because of their thoughts and souls. Without mutual aid and fraternity, man would not be human, and what is the difference between him and those invaders? Although this is a world where the strong survive, should we go with the flow? ”

"You can't always be responsive."

"It's nothing to us, right?"

The figure shook his head with a smile and said, "Ava is indeed a very attractive woman, but you should know that you will not have a result with her. ”

"Of course I know it, so I think I should do something."

"For her?"

"For them." Chu Tianjiang let out a long sigh and said, "Anyway, Mr. and Mrs. Jack helped me, took care of me, and let me stay. Before I leave here, I want to do something for them so that they can live a better life, and I can repay them for their kindness. ”

"There are other ways to do something like this." The figure pointed to the long sword that Chu Tianjiang was building.

"It's something I can do." Chu Tianjiang sighed secretly. "Actually, I don't know why Lu Dao wants to agree to teach Ava swordsmanship."

"Really?"

Chu Tianjiang shook his head with a smile and didn't say anything more.

Probably guessed Chu Tianjiang's thoughts, the figure didn't say anything more, and disappeared.

The next morning, when Chu Tianjiang came to the ground, Ava was already doing warm-up exercises. Probably saw what Chu Tianjiang did yesterday, she was running around the farm for a long time, and she was not wearing a fur coat, and she was bubbling with Han Qi on her body, and it looked like she had been running for a long time.

Taking off his animal skin coat, Chu Tianjiang caught up with Ava.

"Early."

"Early." Ava nodded at Chu Tianjiang.

Chu Tianjiang didn't say much, ran a few laps with Ava, and only came to the central open space after his body became hot.

"This sword was made especially for you." Chu Tianjiang threw the long sword he had built last night to Ava.

"It's ......"

Pulling the sword out of its scabbard, Ava was startled and then smiled sweetly. This is indeed a sword made for her, the blade is very narrow, without any decoration, the length of the blade is about seventy centimeters, with the hilt, the total length is less than a meter. Obviously, this is a longsword that is more suitable for thrusting, and it is very light, suitable for women who lack strength, whereas the previous longsword was more suitable for men.

"Your strength is insufficient, so don't learn from Schneider, his swordsmanship is not for you." After taking the "Blood Wave", Chu Tianjiang said again, "You must focus on dexterity, don't compete with your opponent hard, and don't fight to the death." Seize the opportunity and stab your enemies to death with a single sword. ”

Ava nodded, indicating that she understood what Chu Tianjiang meant.

"Ready?" Chu Tianjiang pulled out the "blood wave".

"Does this sword have a name?"

"Nope."

"Spike, how's it going?"

"Whatever." Chu Tianjiang put on a good posture. "Do as I say, attack me. Remember, don't try to compete with me until you have to. ”

Ava nodded, and set up her stance.

This time it was not a fight, nor a competition, so Chu Tianjiang did not fight back, but constantly corrected the problems in Ava's swordsmanship. Although Chu Tianjiang is not a master of swordsmanship, he has been systematically trained and knows a lot of swordsmanship knowledge, and he can also get some relevant information from the figure.

The training lasted all morning, and Ava's progress was very noticeable, but many of the habits still haven't been broken.

There's no way around it.

Before meeting Chu Tianjiang, Ava's swordsmanship was learned from Schneider, and Schneider's moves were not suitable for her at all. To put it bluntly, Schneider's open-minded style of play is all about strength, and Ava obviously doesn't have that much strength. Not to mention that she didn't meet a master, she met a real master, and Ava used Schneider's swordsmanship to find death, and there was no chance of winning at all.

In the afternoon, Chu Tianjiang continued to participate in collective labor.

Whenever possible, snow must be collected and disposed of. Ava was consciously involved in the labor, and under her influence, three other guards were also involved.

In the evening, Chu Tianjiang refused Ava's invitation and returned to his home.

For the next three days, the weather was fine. Every morning, Chu Tianjiang practiced swords with Ava as usual, and the other three guards also joined in. Although Chu Tianjiang did not agree to teach them swordsmanship, a few more opponents would also help Chu Tianjiang improve his sword skills. In the afternoon, they also participate in collective work, mainly to clear the snow and ensure that there is enough water to irrigate the crops next summer.

However, the fine weather ended on the evening of the fourth day.

The arrival of the snowstorm indicates that in the following days, you can only go out at noon every day, and you must control the outdoor activity time to less than half an hour. If manual labor is not done, it will freeze in less than ten minutes, and the stored food is not enough for everyone to participate in manual labor. On the third day of the blizzard, even at noon, the outside temperature was below minus 60 degrees. No one came out to do the event, everyone stayed at home honestly. Although he had a colorful battle armor, Chu Tianjiang was not afraid of the cold, but no one else went out, and he had no reason to go outside. Besides, the heavy snow that was flying all over the sky also made him nowhere to go.

Using this time, Chu Tianjiang forged a long sword for each member of the guard.

Although he didn't have any feelings with those guards, even to Ava, Chu Tianjiang was very indifferent, but he knew that these weapons could give them a greater chance of survival in this cruel world. In any case, the farm was Chu Tianjiang's first home in this worldly realm, even if it was only a temporary home. Without Jack and them, Chu Tianjiang would not be able to survive here, let alone survive the harsh winter.

Chu Tianjiang wanted to repay them, and the best way to do it was to give them a greater chance of survival.

Of course, in addition to weapons, Ava also needs armor.

Although it is more cumbersome and takes more time to build armor, in the harsh winter when blizzards are raging, the last thing is time.

"You're going to arm them all?"

"Can't you?"

"It's not that it can't be, but what's the problem?"

Chu Tianjiang glanced at the figure and said, "You have to find something to do." ”

"You're going to be so kind, why don't you go to Sophia, or Ava. I believe that in addition to weapons and armor, they also need newborns. ”

Chu Tianjiang rolled his eyes, a little speechless.

"If you could keep a man and a woman, they would be happier."

"That's right." Chu Tianjiang suddenly thought of a question. "Don't you think it's strange to hear Jack say that the birth rate of babies is very low, and there was only one newborn baby last year?"

"It's not surprising."

"What?" Chu Tianjiang looked at the figure.

"Human beings are living beings, and they are also affected by the natural environment. Knowing the physiological phenomenon of women, why do you only come once a month? ”

"Moon!?"

The figure nodded and said, "Although the relationship is not very obvious, there are some relationships. The moon's gravitational field disappears, altering a woman's ovulation cycle. We have been researching this issue for a long time, and we have come to the conclusion that the human fertility rate will definitely be significantly lower. In the past, we could also maintain fertility through technological means, such as IVF, but now there are no such conditions. ”

"This ......"

"Of course, in our time, the impact of the reduction in fertility was not obvious, mainly because the average life expectancy of human beings has been greatly extended, and the life cycle of fertile children has also been greatly extended, and it is not a problem for a couple to have more than ten children at all, but now it is obviously different."

"Life expectancy has decreased?"

The figure nodded. "The oldest man on the farm is in his sixties."

"This ......"

"There are also some factors that affect fertility, such as a decrease in the hormones secreted by women, and the lack of nutrition to keep up, which is not a simple problem anyway."

"There's no way to fix it?"

"Not yet. Maybe the church has a way, but we don't. ”

"The church?"

"According to my observations, almost all the children on the farm are born a month before the harsh winter comes, so their mothers are conceived in the spring. If my guess is correct, there must be a way for the church to impregnate women, and it is used as a means of control. ”

Chu Tianjiang nodded thoughtfully, this is entirely possible.

In this world, the most valuable asset in this world is the population, and everyone wants to have more children, so the church can use this to control other people and convince the common people that only God's believers can conceive and give birth to children. It is not difficult to do this, some drugs or foods that contain estrogen and can enhance the physiological activity of women are sufficient.

Just as Chu Tianjiang was thinking about this question, there was a noise outside.

Daredevil!?

Chu Tianjiang was secretly startled, left the cellar, and entered the underground passage.

The Night Demon hadn't been to the farm for almost half a month, and it seemed that the cold had affected them as well. Tonight's temperature is around minus 80 degrees, which is colder than ever. If the Daredevil is also afraid of the cold, it is obviously a very unusual thing to come to the farm now.
