"Well, the poison in this water has been completely removed!

Feng Qingchen's voice trembled, and as he spoke, he even drank the water in the bowl, and he didn't know whether he was excited or shocked on his face, in short, he kept changing. → eight → eight → read → books, .↓.o≥

I've never seen this kind of detoxification, it's unbelievable!

As soon as everyone heard Feng Qingchen's words, they cheered happily, if it weren't for Ye Xuanling blocking on the side, these people would have rushed up and lifted Qiao Nianxi up!

Alive, finally alive!

An experiment was successful, Qiao Nianxi's face was filled with joy, and she turned her head to look at Ye Xuanling, her squinted eyes squinting with a hint of playfulness.

It's magical, and there's nothing magical about it.

The iron content of the water in the Chizi River is too high, and the water quality is acidic, so Qiao Nianxi asked the carpenter to make this simulated sink according to the source of local drinking water.

The ash placed in the first water storage area is alkaline, and the water stays in this area, and the acid and alkali neutralization can form some iron ions into precipitation.

Most of the precipitation can sink to the bottom when the water is still, and a small part of it flows through the spunyarn and sawdust, and then precipitates again, and finally there are almost trace amounts of iron ions left in the water, which is naturally drinkable.

"It's just a miniature simulation, and for the people's water situation, we need to build several drinking water gates, and the plant ash and sawdust have to be replaced in large quantities, so I don't know if it will work. Qiao Nianxi looked up at Ye Xuanling as she spoke.

Ye Xuanling's gaze still stayed on the sink, thought for a moment, and turned his head to look at Qiao Nianxi: "After the sawdust is dried and wiped clean, it will burn to plant ash, which can be used here, as for sawdust, if the tree vegetation is increased every year to supply sawdust, it should not be too much of a problem." ”

"Yes!"

The big head next to him listened to Ye Xuanling's analysis, and took over the conversation: "There is a vacant land in the back mountain, and the grain does not grow, but the poplar trees grow very quickly there, if the wasteland is cleared to supply sawdust, it will not be too much of a problem!"

The geographical advantage can be regarded as giving everyone a way to live, and the big head quickly summoned the craftsmen of Xiaozhou City to stand by in front of Qiao Nianxi.

An hour later, Qiao Nianxi gave the drawings he had drawn before to the craftsman, and explained the details, and officially started work at noon.

Here the craftsmen make the sink, and there are elite soldiers who build the periphery by the river according to the size of the sink, Qiao Nianxi and Ye Xuanling are not idle, personally supervising the work day and night, and every detail is checked in place.

Five days later, the first drainage tank that everyone worked on overnight was completed.

Sawdust is ready-made and left over from making sinks, and plant ash is the cleaner ash left over from cooking porridge during this time, and everything is taken at will.

A drainage port has been built at the riverside interface, and there is a gate next to it to control the flow of water into the storage area, and the subsequent areas are also equipped with gates to control the flow of water, and the water introduced is easy to control.

I have to say that there was no such high-tech craftsmanship as modern in ancient times, but the manual work of craftsmen is also incomparable to modern times, just looking at this sink made Qiao Nianxi reveal the virtue that he had never seen the world, and then looked at the details, his jaw of surprise was about to fall to the ground!

Everyone watched with excitement the reaction of the river water after flowing through the drainage tank, Qiao Nianxi and Feng Qingchen tested the final water quality, and when the water flowing through the tank was brought back to the jar, the entire Xiaozhou City was boiling!

Ye Xuanling and Zhang Yuan are the gods of war who saved everyone's lives, Qiao Nianxi is the female Bodhisattva who relieved the suffering of the people, no, it is even more divine than the Bodhisattva, when the Bodhisattva didn't care about everyone's lives, it was Qiao Nianxi who dragged everyone back from the ghost gate!

This night, the elderly clansmen of Xiaozhou City led everyone to hold a god ceremony for Qiao Nianxi, and when the beads that have been passed down from generation to generation are hung on Qiao Nianxi's neck, she has become a god worshiped by the clansmen!

After tossing all night, he finally regained his calm, and after so many days, Qiao Nianxi finally breathed a sigh of relief, couldn't sleep, and dragged Ye Xuanling for a walk in the woods in Yanbian.

The two of them talked about the past two days while walking, Qiao Nianxi looked excited, and as she was talking, she seemed to feel something, and suddenly turned her head, and a thin child followed behind them, too late to dodge, and was caught.

"Why are you following us?"

While speaking, Qiao Nianxi squinted her eyes at the child, who seemed to be a little familiar, stared at it carefully, and remembered that it was the child she met at the city gate.

Seeing that he had been discovered, the child hesitated for a moment, raised his feet and walked over, bowing his head with a little shyness on his face: "Sister...... See the princess and princess!"

The child didn't finish saying "sister" and seemed to realize that he had said the wrong thing, so he hurriedly changed his words, and knelt on the ground and kowtowed while speaking.

"Hurry up!"

Qiao Nianxi stretched out her hand to pull the child up, looked at the nervousness on his face, and couldn't help but hook the corners of her lips: "It's okay to call my sister, what's your name?"

"I, my name is Baby!"

The baby's voice was still a little nervous, and after a moment of calmness, she reached out and handed the thing she was holding to Qiao Nianxi: "Grandma said that this is a rhinoceros bone that has been passed down from generation to generation, and it can bless peace......!" I've washed the rope!"

Qiao Nianxi took it from the baby's hand, and looked closely at a round pendant worn with a rope, which was often rubbed, and a uniform layer of grease appeared on the surface.

I didn't want to accept other people's things, but listening to the baby's sentence "It's been cleaned", Qiao Nianxi couldn't help but swallow back the words of refusal.

If he doesn't pick up, the child will think that he is disgusted, and the mud on his feet should have been followed for a long time.

"Okay, the things that the baby sent, my sister will wear them every day in the future!"

As he spoke, Qiao Nianxi hung the pendant around his neck, looked at him grinning, and reached out to pat him on the shoulder: "How are you and grandma doing now?"

As soon as he said this, the look on the baby's face became even brighter, and a big smile bloomed at the corner of his mouth: "My grandmother and I lived in a new house, and my brother in white has cured my grandmother's illness, and now I can stand up and walk, everyone says that my sister and brother are the bodhisattvas who save the world!"

As he spoke, the baby looked up at Ye Xuanling on the side, still grinning, although he had a serious expression on his face, he didn't have the slightest feeling of coldness.

This kind of news made Qiao Nianxi have a great sense of accomplishment, in his previous life, in addition to training, he was on a mission and killing people, and he never knew that saving people would be like this, especially after saving so many people!

I don't usually feel much when I watch TV, but it's different when I'm there, and my nerves are always so sensitive.

"You have to take good care of grandma!" Qiao Nianxi touched the baby's head and smiled gently.

"Hmm!"

The baby responded, raised her head and swept her gaze over Qiao Nianxi and Ye Xuanling's faces, and said seriously: "I will also learn my skills in the future and save others like my brothers and sisters!"

With an ambitious immature voice, Ye Xuanling laughed, but after experiencing this, Qiao Nianxi believed that this child would work hard for his words.

When the baby left, Ye Xuanling turned her head to look at Qiao Nianxi, and saw that she was holding the rhinoceros bone pendant given by the baby in her hand, and there was a layer of depth between her eyes.

"You're such an incredible woman!" As she spoke, Ye Xuanling reached out and put her hand around Qiao Nianxi's shoulder.

Qiao Nian paused for a moment, looked up into Ye Xuanling's gaze, and thought for a while, "Have you already noticed that my hands are different from others?"

Ye Xuanling didn't expect her to say it like this, and nodded instantly, but didn't ask.

Qiao Nianxi raised her eyebrows, and in an instant, she bent her hand into a claw and stretched out towards Ye Xuanling, calling out in a terrified voice: "I'm a monster!"

Ye Xuanling was stunned for a moment, grabbed her hand, and dragged her whole person into his arms with his wrist and wrapped her: "You are my treasure!"

This sentence made Qiao Nianxi's heart tremble, turned his head to look at him with a serious face, somehow felt his eyes be hot, buried his head in his chest, and said sullenly: "I'm not a monster, I will tell you all the secrets about me slowly in the future." ”

Ye Xuanling didn't speak, he reached out and touched her head gently, knowing that she had a lot of secrets, but he also knew that she didn't want to say it for the time being.

Actually, what's the matter if you don't talk about it? She's still the girl she likes!

Over the next few days, tanks were built in almost all parts of the river where drinking water runoff, and there was little need to transport it from distant waters.

However, the solution of the water source matter did not completely relieve people's breath.

In the past, when the people rioted, they had burned the disaster grain brought by Gao Jin, but now the follow-up food has not arrived, even if the grain collected from Sun Jiang is still a little nervous.

Moreover, it has rained heavily in the past two days, and Gao Yun's team has also been delayed a little, and now the food in the city can only last for three or five days.

Not only food, but even Weiyang grass is in short supply.

The Weiyang grass brought by Feng Qingchen was cooked with porridge to delay everyone's condition, but to be cured, those residual leaves picked up by the river were far from enough.

Moreover, after all, the river still needs to rely on Weiyang grass to maintain balance, and the surviving ones cannot be collected too much.

Seeing Feng Qingchen frowning and pacing back and forth in the room, Qiao Nianxi's head was dizzy, and he reached out and grabbed him, not angry.

"What's the use of you going around in circles! This isn't the only place in the area where there is Weiyang grass, right?"

While speaking, Qiao Nianxi rolled his eyes, turned his head and ordered the soldiers outside to find the big head.

Feng Qingchen looked at Qiao Nianxi and didn't speak, her brows still twisted into a pimple.

Although he is used to wandering in ordinary times, after all, the doctor is benevolent, not to mention seeing so many people who are suffering and suffering, the feeling of powerlessness makes his heart very depressed.

Qiao Nianxi ignored Feng Qingchen, turned his head to take the few remaining Weiyang grass leaves, and the little finger of his left hand inadvertently touched the grass blades for a moment, then turned around and walked out.

Ye Xuanling knew that she had an idea, so she didn't ask too much and followed her out.

Out of the tent, Qiao Nianxi submerged his fingers into the dirt, and with the memory of the material analysis in the Weiyang grass leaf just now, the search system of the chip radiated a detection signal.

"Across the river in the southwest, there is a large area of Weiyang grassland. ”

Qiao Nianxi stretched out his hand and pointed in the southwest direction as he spoke, according to the detected information, that place was about fifty kilometers away from Xiaozhou City, not very far.

"The princess is right!
