Quick travel: I am bound by the longevity system

In the afternoon of that day, Lu's Bookstore put these papers on sale and sold them out quickly. Fortunately, there was a lot of stock in Zhuangzi, otherwise there would not be enough for these students to grab.

Lin Jiu thought for a while and sent a copy of the formula for the second-level paper to Mr. Lu and Mr. Lin respectively, and then continued to encourage the craftsmen to continue to improve the papermaking technology.

"Madam, this is the harvest of each farm this year." The old housekeeper handed an account book to Lin Jiu.

"This year's harvest is good." Lin Jiu flipped through the ledger, calculated the total output with an abacus, and said to the housekeeper with a smile.

"Firstly, the weather has been good this year, and secondly, thanks to Madam's new planting method and fertilizers, the crops naturally grow better than before." Butler Lu said with a smile, "Even nearby farmers have asked us for advice, but there is no Madam With their consent, no one dares to publicize these methods.”

"There is no need to hide it. If someone comes to ask, just let the people in the village teach them the method."

"Yes." Butler Lu nodded in agreement. Seeing that Lin Jiu had no other instructions, he withdrew.

Lin Jiu stood up, tidied her clothes, and prepared to accompany Aunt Lin.

"Mother." Lin Jiu walked into the Buddhist hall and knelt beside Aunt Lin.

"We're done." Aunt Lin stood up, and Lin Jiu quickly helped her out.

"Well, I'm done."

"Mom, Rui'er Xiu Mu tomorrow, let's go to Taoshan as a family to play!"

Taoshan is a small mountain outside Jianing County. Legend has it that there was no mountain in Jianing originally. One day, a peach suddenly fell from the sky and landed on the ground, forming a small peach-shaped earth bag. This earth bag would grow one meter every day for one year. After that, today's Taoshan was formed.

On Taoshan, in addition to peach groves, there are also many peach blossom stones, which seems to further confirm the origin of Taoshan.

"Okay, then we will take the children to Taoshan." Aunt Lin nodded with a smile.

The next day, the family passed two newly built archways in a carriage.

"Rui'er, what are you looking at?" Lin Jiu asked worriedly when seeing the child's cold eyes.

"Mother, one day, the child will push these two archways with his own hands." Although his voice was still a bit childish, Lin Jiu could see the determination in his eyes.

"Brother, Han'er will push with you."

"Mother believes in you." Lin Jiu rubbed the heads of the two children.

The carriage quickly arrived at the foot of Taoshan Mountain. Lin Jiu helped Aunt Lin step onto the steps up the mountain, while Lu Rui held Lu Han's hand and followed step by step.

"Mom, sit by the pavilion for a while." Halfway up the mountain, Lin Jiu helped Aunt Lin sit down beside her.

"Mom, can I pick peaches?" Lu Han pointed to the peach tree not far away, with some small peaches hanging on the tree.

"Young master, not only is it small, but it is also extremely hairy. It tastes so hard that you can't even bite it. This is not delicious." Grandma Lu said with a smile.

"I won't eat it, so I'll just pick two for fun."

The peach trees in Momoyama are all hairy peach trees, and they produce a lot of peaches every year. However, because they are difficult to bite and there is no juice in them when eaten, even children don’t like eating them, so almost no one comes to pick them.

"Then be careful. And don't go too far."

"Got it, mother."

"Don't worry, mother, the child will look after his brother."

"Well, then you go play for a while and come back later for barbecue."

In preparation for today's trip, Lin Jiu ordered the kitchen to prepare a lot of ingredients yesterday, just thinking about having a barbecue here today. At this time, the maid and mother-in-law have already set up the rack, and they are just waiting for the charcoal to burn before they can barbecue.

"Yes."

The two brothers walked out of the pavilion holding hands, and Lin Jiu asked the waiter and maid to follow behind.

"Mom, eat some snacks first." Lin Jiu placed the snacks in front of Aunt Lin and made her a cup of tea.

Aunt Lin picked up a piece of pastry and placed it in front of Daju, "You're greedy! Eat it quickly."

"Meow." The system meowed, and then started eating in small bites.

After finishing a piece of pastry, the system looked at Aunt Lin eagerly.

"Meow meow, more."

Seeing this, Aunt Lin smiled and handed it a piece of pastry. After eating the pastry, she looked at the ingredients aside.

"Haha, you greedy cat." Aunt Lin rubbed the system cat's head, "Jiuniang, grill a fish for Daju."

"Okay? Mom, what do you want to eat?"

"The dried tofu baked last time was good. You can bake two skewers for me." Aunt Lin hugged the big orange and looked into the distance happily.

"Mom, my brother and I are back. My brother and I picked up several stones. My brother said to take them back to grandpa to see what kind of stones they are." Lu Han held up a stone and handed it to Lin Jiu, "Mom, do you know this stone?" What kind of stone is it?”

Lin Jiu's heart moved when she saw the reddish-brown stone in Lu Han's hand. She immediately took it and sat next to Daju to watch it carefully.

"System, scan it."

"No need to scan, it's just what you think. It's iron ore, and it's also magnetite with a high iron content. However, this piece turned into hematite after oxidation. Host, this iron ore is not small."

"Mom, do you recognize what kind of stone this is?" Lu Han blinked and looked at Lin Jiu.

"Isn't this what everyone calls the peach blossom stone? Look, there aren't stones like this everywhere on this mountain. You kids just pick them up as treasures." Lin Jiu put the stone on the table aside, and then dipped it in with a handkerchief. Wipe him with water, "Look, your hands are covered with dirt."

"hey-hey."

"Just laugh and eat quickly!"

Lin Jiu handed the barbecue to the two brothers.

Lu Rui looked at his mother inquiringly. He felt that her mother must know what kind of stone it was. It would be inconvenient to say that she didn't know it now.

Lin Jiudang didn't see Lu Rui's inquiry, but sat next to the grill and grilled them.

"Grandma, you eat this." Lu Rui handed a skewer of grilled meat to Aunt Lin.

"Ruier's grilled meat is pretty good." Aunt Lin said with a smile.

"Mom, you eat too." Lu Rui handed another skewer of barbecue to Lin Jiu.

In the afternoon, the family went down the mountain with more than satisfied. Of course, before leaving, Lin Jiu did not forget to ask the servants to take the stones picked up by the two children with them.

Lu Rui saw this scene, and he was even more certain that his mother knew these stones.

"These stones were picked up by the two young masters. Let's put them in the study!" Lin Jiu directed the boy to move the stones picked up today into the study. "Rui'er, come to the study with mother. Mother will test your recent studies."

"Yes, mother." Eunuch Lu Rui followed Lin Jiu respectfully.

After entering the study, Lin Jiu sent the waiter away from a distance. First, Lu Rui was tested on Lu Rui's homework. Lu Rui answered them one by one and was able to draw inferences. Lin Jiu nodded with satisfaction.

"Yes, I originally thought that you would not be able to keep up with the progress of Qingshan Academy, but now it seems that I was overly worried."
