This night, she flipped through the ancient books, there was no practical way, the 800,000 army was fortunate to be on the front line, how could they be thirsty to go to the battlefield!

"Xiaoli, you haven't slept all night, this is a peach pot sent by the palace." Yao twisted the peach sealed in the jar with chopsticks and put it on a white porcelain plate.

"Hmm."

She didn't have the heart to eat anything right now. Watching Yao pick out the peaches one by one, he thought about how to filter the water clean.

At this time, a drop of peach juice fell on her shirt and instantly soaked into her clothes.

When people make wine, they will take cloth to filter the debris in the wine, but the cloth can only filter large residues, and the water in the Qingshui River is so badly damaged that you may have stomach trouble if you drink it.

It is not enough to have cloth alone, the ancients had a method of using charcoal to cross the water, but preparing a large amount of charcoal wastes wood fire, and the time cannot catch up.

Suddenly, she grabbed Yao's hand and shouted excitedly.

"I've figured it out!"

Early in the morning, she took people up the mountain to see a lot of bamboo tubes back, and then found a cloth and stuffed it into the bamboo tube, and used the big water wheel outside the city to send the water into the bamboo tube, after layers of cloth filtration, and then to the final charcoal filtration to eliminate the odor, and then sent into the pot to boil the precipitated water, which is always reassuring.

Soon the third day passed, and the two armies went to the Qingshui River, which was downstream, but the enemy had already piled up dirt bags in the middle of the river to isolate the sewage, but no matter how clear the water was, it would have to be turned red by the blood today.

"Kill!"

The drums of war sounded, and the general led hundreds of thousands of troops to charge into battle, fighting happily, and when they were having fun, the army of thousands of illusions was defeated one after another.

The enemy army once pursued as fierce as a tiger, but did not want to be a trap, rolling down a piece of rocks, walking in front, or dead or wounded, none of them were spared, and the enemy troops who were lucky to survive in the back retreated, and encountered outflanking, it can be said that there are tigers in front and wolves in the back, and they are in a dilemma.

At this time, in the midst of the Thousand Illusions army, there was a loud bang, and countless soldiers were blown apart.

Lige's eyes widened, what was that! How lethal it is!

The situation, which was already about to win, changed in an instant, and the Thousand Illusion army was dodging the sudden explosion and the drums of war in all directions, and it became more and more chaotic, so it had to retreat.

This battle ended in defeat.

After retreating to the city defenses, the army of more than 700,000 was now drastically reduced to 400,000.

Lige looked at the black fragment in her hand, which she had picked up from the dirt in her hasty retreat, and it was such a small piece of thing that forced them back into the city.

"Xiaoli, this kind of thing appeared in the big war more than ten years ago, it is called explosives, but compared with the scene described in the historical records, this one seems to be more powerful."

"Such a terrifying thing, now being used by Lan Qiguo, I'm afraid it will be even more difficult for us." She held her chin, others were still pestering her mother to ask for candy at this age, but she went to the battlefield, difficult for her family and country, she was just a child.

"The bomb first appeared in the hands of Empress Baili Wuxin of Qian'anguo, I heard that she was inspired by the signal flare, so it is better for you to study it." Yao knows that she is smart, always learns faster than others, and never admits defeat.

"I can't find a way to develop a bomb for a while, if only I could steal the method of making it from the enemy." She grabbed her hair in embarrassment, who should she send, let Yao go, she was reluctant, what if Yao was in danger.

Thinking about it, it seems that those who have the ability to probe the enemy camp are not very suitable.

"Xiaoli, let me go."

"No, I'm selfish, so I don't want you to take risks."

"I'm glad to hear that Xiaoli cares about me so much, but Xiaoli doesn't want to end the war early."

"I ......" It would be good to end the war sooner, but she didn't want to lose Yao because of an accident.

"I'll go with you." She tugged at Yao's sleeve, afraid that he would never return.

Yao warmed up, bent down and hugged her into his arms, sniffing the fragrance of peach blossoms in her hair.

"Without Xiaoli's permission, Yao would not dare to die."

Her face was slightly red, since the two of them had made their minds clear, she couldn't just hug and hug, every time Yao was very close to her, her heart would always beat fast.

"If I die, my soul will crawl back for me."

"Yes."

After Yao left and went to the enemy barracks, whenever she was free, she would wander out of the world, thinking about what Yao was doing at the moment, whether she had enough to eat or something, and half a month passed.

"Meow~"

"Bayu, you're finally awake again, hug it."

"Meow~" Bayu stuck to her body and coquettishly, her white hair exuding a little light green shimmer.

"Uh~" Lige suddenly throbbed all over his body, and he was holding his heart with shortness of breath, which seemed to be torn apart.

"Girl, the heart of Sansheng is here with you."

"Who!" She looked around warily.

Bayu seemed to sense that something was wrong, and immediately cut off the aura that interacted with Lige's heart while it had just started.

Now, the reincarnation of thousands of lives has reached the last and most critical life, living in the body of a phoenix to cast a delicate heart, but the exquisite heart has not reacted for a long time.

Little master, you have tasted all the flavors in the world, what is still missing.

Lige's face gradually improved, but there was still a burst of pain in his heart, could it be that he was sick?

She knows a little about medicine, but she only knows a little about the skin, and she can't see what's wrong with her.

"Rain! I'm hungry. She took Bayu into her arms again and stroked her hair, took out a bottle of peach cans from under the bed, opened it and fed it to him.

"Meow."

"Lord Wang, Yao's letter." At this moment, a secret guard suddenly appeared in the room, kneeling on one knee, holding a creed wrapped in a white envelope.

She was overjoyed, happily put Bayu on the chair, wiped her hands and carefully opened the envelope.

"Your man is in my hands, if you want to see him for the last time, tonight, enter the camp alone, and put pen to paper"

I'm really afraid of something. But with Yao's concealment technique, she can escape even if she is discovered, she is faintly uneasy.

This matter is related to Yao's life and death, even if it is Daoshan, she has to break through tonight.

"Meow." Bayu jumped into her arms, as if he didn't want to leave her half a step.

"Bayu, I know you are very spiritual, if you can understand my words, nod, I will take you with me tonight, if you don't understand, just go back to bed to rest and take care of your body as soon as possible."

For Bayu, she can be said to love it on the tip of her heart, and there is always a stronger and stronger bond that pulls her.

"Meow~" Bayu nodded, no matter where she goes, she must be in front of him all the time, so that it is convenient for him to save her in time.

"It seems that you can really understand human speech, are you a demon?" It would be better if he was like Dugu Lian and had some strange and fun mana.

Bayu shook his head, now he can't speak, and it is more difficult to communicate with the little master.

"Can you turn my eyes blue, then?" Dugu Lian's blue eyes, with the charm of a demon and the agility of a fairy, even when they are full of cold, they are just icing on the cake, and they are even more beautiful, which makes her envious.
