After saying that, Yang Qingwei rolled up his sleeves and said to Doctor Zhong: "This is the vaccine that Master Nineteen just gave me. It can prevent infection."

"I see. But... is it really possible?" Although he already knew that An Tingyu was the Nineteenth Concubine, Doctor Zhong still had doubts. Could a small soybean really have such a big effect? ​​Could An Tingyu have made a mistake?

An Tingyu proudly raised her head and chest and said calmly: "I don't joke with my life."

Although she was a doctor, she was not so great as to disregard her own safety and come to die, not to mention that chickenpox was just a common skin disease in her eyes, and Doctor Zhong's suspicion was unnecessary.

Hearing this, Doctor Zhong finally nodded, "Okay! Then plant it on me too."

With the approval of Doctor Zhong, the other doctors also nodded. Just like that, under the leadership of An Tingyu, the military doctors and doctors from the Imperial Medical Bureau took action. They even gathered all the doctors near the border, and then acted separately according to their assignments.

This busyness lasted for several days. On this day, An Tingyu did not get some space until the sun set. She sat tiredly on the soft couch covered with tiger skin. Behind her, a pair of big hands suddenly pressed on her shoulders. An Tingyu was stunned and turned around, only to see Jing Aotian standing behind her without her knowing when.

"Are you tired?" Jing Aotian said gently, rubbing her stiff shoulders.

An Tingyu smiled and said, "If your opponents saw you like this, their jaws would probably drop."

"I'm shocked, but a woman who takes care of herself is afraid of what others think of her."

Hearing this, An Tingyu curled her lips and smiled again, "How is it going on your side?"

"We've done what you said. Don't worry about it. Be careful not to overwork yourself." Jing Aotian took a step forward, sat beside her, and hugged her gently.

An Tingyu leaned on his chest, closed her eyes, and enjoyed the warmth for a moment.

"Tomorrow..." Jing Aotian lowered his head and wanted to say something, but when he lowered his head, he found that the person in his arms had fallen asleep. Jing Aotian smiled slightly and gave her a gentle kiss on the forehead.

She was exhausted these days from traveling and dealing with the plague.

"proud……"

"Shh!" Jing Aotian put his finger to his lips, signaling the visitor to be quiet.

Liu Yunsheng was stunned, then closed his mouth until Jing Aotian carried An Tingyu to the bed and they walked out of the room.

"It seems that these words have really exhausted her." Liu Yunsheng glanced at Men Pin with admiration in his eyes. She was just a little girl, but An Tingyu shouldered a heavy burden and was no less capable than those male doctors. She was even more persevering. I really don't know how the waste before could become what she is now.

Jing Aotian nodded, then skipped his question and said, "Is there anything wrong?"

Liu Yunsheng shrugged. "It's not a big deal. The water pipes are already built. You wouldn't believe it, it's truly amazing. The water that was originally at the mountainside has now flowed to the camp on its own, and there are now water outlets throughout the camp. This way, we won't be afraid of Mo Youcan's fire attacks."

The more he spoke, the more excited and impressed Liu Yunsheng became. He added admiringly, "It seems her brain is really different from ours."

"That's right. It's so effortless to bring water into the position. No one has ever done it since ancient times. Who else can do it?" A shrewd light flashed in Jing Aotian's sharp eyes.

An Tingyu asked them to cut some bamboo, then pierce the bamboo joints with swords, and then connect the bamboo one by one, extending it from the side of the mountain all the way to the camp. The water flowed from high above, and they just led the water down like that. It seemed like a simple thing, but no one had ever thought of it.

Jing Aotian thought he was smart, but compared to An Tingyu, he also admitted that he was not as good as her. He didn't know how An Tingyu could come up with these wonderful methods, but they were very practical and effective.

"By the way, Aotian, do you think Mo Youcan is really interested in Miss An?"

As soon as these words came out, Jing Aotian's handsome face, which was originally smiling, suddenly turned into frost, and a cold air enveloped the surroundings. "If he dares to touch her, this king will destroy him and make him a true cripple king."

"Well……"

Liu Yunsheng was speechless, thinking that Mo Youcan was really pitiful. Before, An Tingyu made him "disabled" and "brain-dead", and now Jing Aotian really wanted to cripple him. What a bad luck!
