Who understands? He traveled through time with a high-spec spatial ability.

Qiao Wanjun said happily, "Mother, have you finally decided to live with your son? You and Father can rest assured, your son will take care of you in your old age."

Madam Xu looked pleased and said with a smile, "Alright, Mother can still move around for now. When we really can't work anymore, we'll come to you to enjoy our retirement. Take the rice seeds back with you, and give them to me when you distribute the seedlings later."

"To prevent us from wasting good things in our old age, you take the things back with you, Third Brother, and study them carefully. Learning real skills is more important than anything else."

Qiao Wanhe readily agreed, "I'll do whatever you say."

Back in the house, looking at his wife, Liu, he was even more satisfied. Indeed, he needed a virtuous wife.

Meanwhile, the Changling Army camp

Xuan Yi knelt on one knee in front of the tent, bowed his head and said, "Your subordinate greets Your Majesty."

A deep, slightly weary male voice came from above, "You're back. Did things go smoothly?"

"Reporting to Master, we have found a place that is easy to defend and difficult to attack, and not easy to be discovered, as you requested. It can accommodate about a person," Xuan Yi replied respectfully.

The other party remained silent, and the tent was utterly quiet, save for the occasional rustling of pages turning. After a long while, "Go and rest. Go and call Xuan Wu in."

"Yes."

When Xuan Wu entered, he saw his master sitting slightly crookedly in a wooden chair. Dressed in plain clothes with black hair, his face was as handsome as jade, his posture was as upright as a pine tree, and his temperament was as noble as an orchid. Every move he made exuded elegance, and he was indescribably noble and dazzling. At this moment, his thin lips were tightly pursed, and his well-defined index finger and thumb were kneading his brow.

Hearing the noise, the hand kneading did not stop. With the other hand, she precisely took a letter from the book and handed it to Xuanwu, "Send this to Father Emperor as quickly as possible. Remember, if anyone notices, destroy the letter rather than risk your own safety."

Xuanwu was deeply moved. How could he not be loyal to a master who cared so much about his subordinates and treated them like human beings?

"Xuanwu obeys!"

He quickly returned to the camp of the First Squad of the Xuanjin Army after leaving the main camp. Since the First Squad was responsible for the safety of the Seventh Prince, it was very close to the central main tent, and Xuan Wu arrived in a few strides.

Only Xuan Yi, Eleven, and Fifteen were inside the tent; the others had gone to carry out their missions. The team had an unwritten rule: no one would inquire about their teammates' missions.

The 15 individuals each possessed unique strengths: some excelled in light-footed skills, others in stealth, some in intelligence gathering, and still others were adept at disguise and possessed high martial arts skills. They would also joke and banter among themselves, and once someone packed their belongings to leave, no one would inquire further; their actions were known only to their master and the person themselves.

"Captain, what kind of rare thing is this? I've never seen anything like it before," Fifteen asked curiously.

"Hehe, this is good stuff. Don't tell me you're only 13. I'm 19 this year, and I've lived 6 years longer than you, and I've never seen anything like it."

Without time to catch up with Xuan Yi, Xuan Wu carefully placed the letter close to his body, packed a small bundle, and tied it to his chest, knowing he was about to leave on a mission. Xuan Yi quickly stepped forward and said...

"Xiao Wu, take this with you, it will be much more convenient. This is how to use it." He took the water bottle and two biscuits that Qiao Jingjing had given him and repeated what Qiao Jingjing had told him to Xuan Wu.

Guards are human too, and they need rest at night. Even if the people can endure it, the horses also need rest along the way. Although there are official post stations, the distance between them varies due to the mountainous terrain. If one were to rest in the wilderness at night, having a water bottle would save time in searching for water.

Under Fifteen's envious gaze, Xuanwu accepted the item without hesitation. He carefully examined the object in his hand, secretly marveling at its rarity. "Thanks, brother. We'll talk again when I get back!" He then swiftly leaped onto his horse, spurring it on with his legs, urging it to gallop forward. The sound of hooves was crisp and melodious, raising a cloud of dust.

Only when he could no longer see him did Fifteen turn his gaze away, unsure whether he envied Fifth Brother for being able to go on a mission or for using his new gadget. Or perhaps, both?

That day, Daba Village became lively again. Qiao Jia's daughter "accidentally" discovered a food called chestnuts while climbing the mountain. After trying it, she found that it could be used as a staple food or a snack. It tasted excellent whether stir-fried or steamed. This rekindled the villagers' enthusiasm, which had finally cooled down.

Daya is truly a lucky girl in Daba Village.

Her good fortune didn't stop there. After the peanut harvest, she dug up a sweet potato in the mountains. After cultivating and planting it, it grew incredibly lushly on a patch of dry land. Digging into the sandy soil, she found that each section of the sweet potato vine was laden with fruit. This fruit was even sweeter than chestnuts and easier to eat. Aside from the negligible drawback of causing flatulence after eating too much, it was definitely a good food.

It's worth mentioning the yield of this crop. Qiao Jia Daya only planted one-tenth of an acre, yet the harvest reached a staggering 700 jin (350 catties). Villager A excitedly grabbed the arm of the person next to him.

"Does it hurt? I feel like I'm dreaming!" Villager B said, feeling both aggrieved and happy. "Why would you pinch me if you were dreaming! Of course it's real." If this were planted on one acre, the yield would be around 7000 jin! That would be enough to feed so many people, I can't even imagine.

When aunts and sisters-in-law came asking for seeds, Qiao Daya was generous and sold them to them at the price of rice seeds. These people were overjoyed and kept praising Qiao Daya and the Lin family for their kindness.

You see, this is real grain! Although rice tastes better, people who are often starving don't care much for sweet potatoes or rice; they're just grateful to have something to eat. Besides, sweet potatoes produce several times more than rice. Not only can they eat their fill, but they can also have some left over, enough to occasionally change things up with rice.

The more they thought about it, the more excited they became. They almost wanted to kneel down and worship Qiao Jingjing. In fact, to some extent, Qiao Jingjing did deserve this worship. She gave people a way to make a living, like a second parent, especially since it was a long-term, enduring way to make a living that benefited the whole village.

However, the Qiao family was kind and only asked for money for the seeds, nothing else. This filled the Qiao family with gratitude, so they spontaneously helped build the house without asking for wages, and left as soon as the work was done. Many hands make light work, and the house was completed in no time.

Qiao Jingjing was astonished by these people, but also felt gratified. She was willing to share her knowledge, but if they were all a bunch of selfish and malicious people, it would be quite disgusting. Fortunately, most of the villagers only wanted to escape hunger and cold, and once their basic needs were met, they were still willing to remain simple and honest.

The village's old woman, who often officiated at weddings and funerals, had no children of her own. Qiao Jingjing gave her some grain and asked her to calculate the auspicious day for raising the roof beam of her new house.
