"Success!" Qin Manwu stared at Jiang Xingchen who was excited. She said something for a moment but the soul came. She really thought there was no hope before. The reason why she waited for two months was due to the last chance of luck, but she didn't expect...

Turning his head, Qin Manwu looked at Jun Bumi, wanting to confirm the news from him, but seeing him as he was also stunned.

At this moment, Dingbei Hou and Tang Chuxue had already rushed over and picked up a little of the precipitated crystal and put it into their mouths.

"It's really successful!" In an instant, the two of them showed ecstasy at the same time.

When the old man saw their expressions, he jumped to Jiang Xingchen, clamped his neck with his right arm, and grabbed his left hand on his head.

"Hahahaha... Little Soul Dan, I really have you, I really solved the problem of salt! How did you think of this method..."

"Success! It's really successful!" Qin Manwu finally reacted, with tears in her eyes. She had invested too much energy in the desert line, which directly concerns her future status in the Great Qin Kingdom... Now, she has finally been saved.

Jun Bumi was the same. He let out a long breath with relief, then looked at Jiang Xingchen who was struggling hard under the old man's arm, and a strange look flashed: "How did his brain grow? How could he know such a method... Is there nothing he can't do as the eldest princess said?"

Tang Chuxue straightened up, and the smile on her face could not be concealed: "Jiang Xingchen, you can do it, I knew you would definitely bring me surprises!"

Dingbei Hou smiled so hard that his beard shook his face and his mouth could not be closed. This was a great contribution! It was a bit exaggerated to say that he saved the country, but he saved the alliance. He avoided the powerful Xuanyuan Tianzong alone, and that super mine vein would not be thrown away!

"After this incident, I see who can stop the emperor's reward... Even Tang Chuxue and I will probably benefit from it! It's so lucky to have this kid by my side!" Dingbei Hou thought proudly.

At this time, Du Rushan, Mei'er and the others also ran out, unable to figure out the situation of the gods, and they were a little confused for a moment.

"Let go! Old man, let go!" Jiang Xingchen struggled hard, and the old man was so excited. It was nothing. The key is that his right hand hurts so badly now.

"Damn it, so joy makes me sad! I can't control my emotions. It's true that I'm going to be very bad..." Jiang Xingchen reflected on himself. He slapped the ground just now. He didn't feel anything at that time, but now it hurts to the bone.

"Stop it quickly. It's not finalized whether it's OK... Don't believe it, I'm so good, old guy, you can eat white flour cakes every day in the future!" Jiang Xingchen had to use his trump card in the end, which made the old man let him go.

As soon as the old man let go, Jiang Xingchen jumped to the side immediately, raised his right hand, which was swollen like a bear's paw, and kept blowing.

"Brother! What's wrong with your hand?" the little girl shouted in a whisper. She hurriedly ran over, and tears flowed down her eyes.

The old man realized that Jiang Xingchen's right hand was swollen like this, and his face changed immediately. This kid is the most agile with these hands. If something goes wrong, it will be troublesome.

He flashed to Jiang Xingchen's side, and the old man made a move like lightning, and a long thin needle lit up a few times in his hand.

When Jiang Xingchen saw the old man coming, he wanted to hide, but his formation was activated but it didn't work. In the blink of an eye, the old man's movements were over and his hands no longer hurt.

"I'll go! This is the old guy's real strength, it's too fast! He hasn't acted seriously before!" Jiang Xingchen shook his hand and said in his heart.

"Boy, does it hurt?" the old man asked.

"It's okay! The old man is good at medical skills!" Jiang Xingchen complimented.

When he heard Jiang Xingchen say that it was no longer painful, the old man breathed a sigh of relief, and then raised his head with stern eyes: "That's right, I'm a great doctor! I'll give you some medicine later, and it will be fine in three or five days!"

Jiang Xingchen turned around and comforted Mei'er, and then he squatted down again. The work he had just finished was only halfway through.

Sure enough, as the temperature continues to drop, not only salt, but also other impurity crystals precipitated.

At this time, his formation finally came in handy. After heating the solution again, he quickly judged the temperature of the salt precipitation and the temperature of other crystals precipitation.

In this way, if you want to completely separate the salt, the process becomes complicated. You need to maintain a certain temperature and continuously add mineral salt to saturate the solution.

"This work is probably going to require a lot of labor, and the temperature control is also a technical job... But no matter what, the problem of bitter salt mine has finally been solved!"

Jiang Xingchen breathed a long sigh and told Qin Manwu the final result.

The ecstatic Qin Manwu immediately wrote a letter to the Great Qin Kingdom and released the Speed ​​Eagle.

Tang Chuxue and Dingbei Hou were not idle either. The news had to be notified immediately by the empire and Luo Yu.

At this time, Jiang Xingchen felt physically and mentally exhausted. He spent the whole day fiddling with the mineral salt and repeatedly doing experiments. It was really laborious and troublesome.

"I'll go and have a rest first!" Jiang Xingchen greeted everyone and turned back to the room.

Dingbei Hou and Tang Chuxue didn't stay for long. They had been in Qingshan Village for a long time. Now that things are resolved, they must go back immediately.

Qin Manwu and Jun Bumi stayed, and they had to quickly transfer people from the Great Qin Kingdom. Jiang Xingchen's salt-making technique is definitely a technical job, and he has to learn it specifically, especially the control of temperature.

The supper was made by Mei'er, and when she was eating, she didn't let Jiang Xingchen take action and wanted to feed him with her.

Jiang Xingchen felt a little awkward when he asked the little girl to feed him. When he was about to refuse, Mei'er had already delivered the spoon to his mouth: "Brother, be good, open your mouth, ah~"

"I'll go! Feed you baby!" Jiang Xingchen's cheek muscles were thrusting, but when he saw the cunning light flashing in the little girl's eyes, he immediately remembered the experience of being forced to feed him by this girl. He couldn't help but shrink his heart and opened his mouth obediently.

"Hehe! So good!" The little girl's face was filled with a victory smile and gently put the spoon into his mouth.

When Jiang Xingchen heard the little girl's words, he was originally a little depressed, but when he saw her cautious look, he seemed to be afraid of touching his lips, and his heart felt warm again.

After that, the little girl didn't say anything, but just fed the whole bowl of rice spoonful by spoonful. Jiang Xingchen didn't say anything, silently enjoying Mei'er's careful care.

After packing up the dishes, Mei'er brought another basin of hot water, squatted down and removed Jiang Xingchen's shoes and socks.

"Mei'er, my brother's hands are fine, you can wash them by yourself!" Jiang Xingchen was really embarrassed.

"Don't move!" Mei'er shouted softly, raised her head, her face was a little rosy, and she said softly: "Last time when Mei'er was seriously ill, my brother took care of me, fed me and... gave me a bath!"

Speaking of this, the little girl lowered her head, but continued to say, "It's been half a year since my brother has been taking care of Mei'er. Today my brother's hand was injured, so of course it's time for Mei'er to take care of her brother!"

Jiang Xingchen was inexplicably moved, stretched out his left hand and gently rubbed Mei'er's head: "Little girl, how can I calculate it so clearly with my brother? Isn't it natural for me to take care of you!"

"It's not natural for Mei'er to take care of her brother? Really!" Mei'er said, pressing Jiang Xingchen's feet into the basin.

"Aowu~ It's hot!" Jiang Xingchen immediately let out a wolf howl.

"Ah!" Mei'er was also startled and hurriedly took out her brother's feet and asked anxiously: "Brother, are you okay? I've tried it, this water..."

Halfway through, Mei'er suddenly found that Jiang Xingchen was pursing her lips, her cheeks kept twitching, obviously she was holding back her laughter, and she didn't look a little painful.

I quickly put my hands in the basin and tried it. It was just right not cold or hot, and it was not hot at all.

"Brother~" Mei'er's little face wrinkled together and she let out a roar.

"Ahem!" Jiang Xingchen hurriedly begged for mercy: "Mei'er, brother is just kidding you because you're too arrogant, you won't mind, right?"

"Hmph!" Mei'er stomped her feet gently, bulged her mouth, and said, "It's up to you! Seeing that your hand is injured, I won't bother with you!"

"Uh!" Jiang Xingchen was stunned when he heard this: "It's over like this, it's a bit different from this girl!"

When he was wondering, the little girl squatted down again, put his feet in the basin, and washed them carefully.

Both of them no longer spoke, and there was only a sound of water squirting in the room.

The soft little hand touched Jiang Xingchen's soles of his feet, which made him feel itchy and wanted to laugh. But at this moment, he really couldn't laugh, and he was immersed in a strong warmth.

"Brother, don't be so excited in the future. If there is really something wrong with your hands, what's going on!" Mei'er suddenly spoke.

"Yes!" Jiang Xingchen nodded: "I won't know anymore, I'm worried today!"

"That's good! My brother has been tired for a day. After washing, go to bed early!"

"Okay!" When Mei'er said this, he was really sleepy. He was soaked in warm water under his feet and was kneading him. The sleepyness arched upwards and his eyes began to fight.

When he was in a daze, he suddenly felt Mei'er greeting him: "Brother, get up, go to sleep!"

"Oh!" Jiang Xingchen opened his hazy eyes, put on his shoes and walked towards the kang.

At this moment, the old man walked in: "Boy, the chess was occupied by the boys of the Shocking Mercenary Group. Give me this picture of yours, and I will abuse the Lord and Budi this...Puff!"

Halfway through his words, the old man suddenly squirted out a big mouthful of water, pointing at Jiang Xingchen and burst into laughter.

"Uh!" Jiang Xingchen was stunned and asked dumbly: "Old man, why are you laughing at? What's wrong?"

"What's wrong! I..." The old man burst into tears, covering his stomach and constantly pounding the table with his right hand.

"Mei'er!" Jiang Xingchen turned his head to greet Mei'er, but found that the girl was missing, and immediately screamed "Not good".

A moment later, Jiang Xingchen heard a roar in the whole village: "Jiang Mei'er~ wait for me!"
Chapter completed!
