After accumulating cement for ten days, construction began on Song Zhuiyan's biogas digester.

In the days that followed, everyone was very busy. Song Zhuiyan was busy supervising the villagers' work and giving them guidance, while Ye Moxun also had to supervise and guide them, mainly focusing on the concrete mix ratio.

If the villagers don't watch over it, they won't understand the proportions. If too much sand and gravel is added, it's like cutting corners. If the concrete isn't up to standard, the pond will be a waste.

When others don't go up the mountain, they also come to check on the progress and learn something. After observing for a few days, someone said that the cement could actually be used to build houses, making the houses very sturdy and resistant to hailstones the size of fists.

This person is really daring. Building houses with cement is something no one does in modern times. Of course, this person also couldn't have thought of using cement to pour floor slabs. Neither Song Zhuiyan nor Ye Moxun mentioned it. Pouring floor slabs requires steel bars, and iron is hard to find here, so where would they get steel bars?

However, what that person said earlier still enlightened Song Zhuiyan. Cement and lime powder mixed together can be used to paint walls, which is more effective than using pure lime powder. With cement walls, rainwater will not seep into the walls on rainy days, and the house can stay dry.

Once the biogas digester is finished, I'll have someone come and paint the walls of my house with cement plaster and renovate the exterior. It will look much better. It's a pity there are no tiles to use, otherwise it would be perfect.

Song Zhuiyan had been thinking about building a biogas digester for a year, and Ye Moxun had also spent a lot of time researching it. So the construction went relatively smoothly this time, and it was completed in about half a month. The biogas digester was not large, and could only accommodate a maximum of one hundred pigs.

"Paint the walls? Paint the walls?" The villager who was asked to help looked puzzled. Having a brick house to live in is already a great thing, why bother painting the walls? Isn't this just making trouble for nothing?

But they heard that after the walls were painted, water wouldn't seep into the house, and the stored grain wouldn't easily get moldy during the rainy spring season. They felt it was quite necessary, so they stopped worrying about it and decided to paint the walls of Song Zhuiyan's stone house first, and then see how it turned out.

This busy period lasted another half month. Because they were all novices, even though we hired seven people, it still took a lot of time to finish painting the walls.

"It's really beautiful, even more beautiful than the city walls of the prefecture."

"I'll get my house cleaned too."

The villagers said the cement gray walls were very beautiful, magnificent and grand. Song Tantan and Ye Moxun looked at the gray house and thought it was just so-so. It couldn't compare with later generations, but it was considered very good in ancient times. It was simply luxurious and high-class, wasn't it?

So the second family to need their walls painted was Zhong Qingyi's family. He didn't have enough food to pay the wages, so he could only exchange labor with others and repay them when they needed help.

Zhong Qingyi's idea was that his house couldn't be too much worse than the Song family's house; it had to be at least similar. Otherwise, it would be a disparity in family background, and how could he propose to Miss Song in the future?

Autumn passed and winter arrived. In the blink of an eye, another year had passed. Song Tantan calculated that three years had passed since she and her aunt transmigrated to the Great Jin Dynasty. Back then, she was just a five-and-a-half-year-old toddler. Three years later, she was almost nine years old.

Ye Moxun is already twelve years old. He has grown taller and taller at a speed that can be seen with the naked eye. He has grown from a short boy to a tall bamboo pole. Perhaps it is because of the good food and nutrition he eats every day. At only twelve years old, he has grown to 1.6 meters tall, which is half a head taller than Azhu, who is two years older than him.

There's also Ye Mo's pet wolfhound, "Taishan," which has grown to a meter long and a meter tall at the shoulder after more than half a year. Its size is enormous, and no one knows how it grew so big. It's a giant wolf that looks terrifying, and most people wouldn't dare to get close to it.

The other wolfhounds are of normal size, 70 centimeters long and over 800 centimeters tall at the shoulder. They grew up in the village and are used to interacting with the villagers, so they don't look fierce.

'Mount Tai' never interacts with anyone except Ye Moxun. It ignores others when they call it, and is very arrogant and aloof.

The only people it ignored were Song Tantan and Song Zhuiyan. No one else dared to call out to it, mainly because just one glance from its eerie green eyes made them tremble, as if they were being watched.

Unsurprisingly, 'Taishan' is the leader of the pack of wolfhounds in the village. He is solitary and aloof, never playing or hunting with the other dogs unless an enemy invades their territory.

Of course, no large beasts have entered the village so far, and no beasts have been encountered when hunting in the mountains. At worst, there is the medicine developed by Ye Moxun. Why should those bastards risk their lives?

"You said it looks big and strong, but it's not all show and no substance. This leader is clearly someone you've spoiled. You've pampered it since it was a puppy, giving it all the best food and things. The other puppies are just grass, they're already at a huge disadvantage from birth."

Ye Moxun only dotes on 'Taishan'. He trained all twelve puppies from a puppy, and they all obey him. So, naturally, the dogs in his household become the leaders.

They were promoted and flattered.

"Look further ahead, don't just focus on the present. Things are calm now, and we don't have a chance to show our 'Mount Tai' yet. You'll see how powerful it is later. This little guy is quite capable." Ye Moxun put on a mysterious expression.

Song Tantan, however, was not optimistic and said with a sneer, "Then I'll wait and see."

Watching someone start fiddling with the herbs for 'Taishan' again, Song Tantan sighed. She seriously suspected that the reason 'Taishan' was so huge was because he had stimulated it with drugs, saying that they were good herbs specially for wolves, to strengthen their bodies and prevent them from being poisoned.

"Take it easy, don't spoil this dog. You're just indulging him like this, turning him into a high-and-mighty playboy who does nothing but show off and sponge off his parents." Indeed, in Song Tantan's eyes, 'Taishan' was a playboy among dogs, especially spoiled, and was served by Ye Moxun like a master every day.

"You'll understand later. 'Mount Tai' deserves to be treated so well. It's very strong and will be of great help to me in the future." Ye Moxun didn't care about Song Tantan's repeated complaints and insisted on taking good care of 'Mount Tai'.

"Awoo." Taishan could sense Song Tantan's disdain for it. Every time Song Tantan confronted it, it would raise its head and let out a low, aloof growl, as if it were sneer.

Ye Moxun patted its head and said with a light laugh, "Don't be angry. Don't stoop to her level. One day she'll know how powerful you are, and then she'll be unable to reach you."

"Come on, I can't afford to associate with you now." Taishan, like Ye Moxun, visits the Song family every day. By the way, it has its own doghouse at Ye Moxun's house, a room specially built with bricks, which is quite luxurious and can be considered as luxurious as a human dwelling.

It eats meat every day, a lot of it. It can eat five rabbits and two pheasants in one meal, and Ye Moxun has to kill it for it and clean its fur and internal organs.

It's like raising pets. It's hard to imagine if one day, when Taishan encountered a pack of wolves in the mountains, he would surrender immediately, or he wouldn't even have the chance to surrender and would be bitten to death.
