After time travel, share a space with your modern family.

Physician Lu and Physician Yang immediately responded, "We can feel it."

"Young man, what are you giving us to drink?" Physician Lin asked Doctor Liu.

Looking at the group, Doctor Liu jokingly said, "I've given you a poison that will make you obey me from now on, hahaha..."

When Ruan Mumu got home, it was almost dinnertime.

After the family finished eating, Qiao Tinghao mysteriously pulled Liu Ziyun to his yard.

As soon as the two entered the door, Liu Ziyun saw Ruan Mumu sitting in the living room drinking tea.

"Girl, how can you just walk into a man's courtyard like that?" Liu Ziyun said, somewhat displeased.

Especially after hearing General Qiao directly say that Ruan Mumu was his daughter-in-law, Liu Ziyun felt even more uncomfortable.

Qiao Tinghao looked at Liu Ziyun with displeasure and said, "What do you mean by this? You think this girl can just come and go as she pleases in my courtyard?"

Seeing that the two were about to start arguing again, Ruan Mumu quickly stopped them, saying, "Don't argue. Is there something important you need to discuss tonight?"

After Qiao Tinghao sat down, he lowered his voice and said, "Today, the archers sent from the military camp came to participate in training. Half of them are my father's shadow guards."

They brought me two pieces of news.

First, the Second Prince suddenly arrived at the military camp last night, saying he was here on the Emperor's orders to find someone.

Secondly, the Second Prince went to Ma Shidao's camp last night, and the two plotted for a long time, but their voices were too low for the surveillance cameras to hear.

Upon hearing that his second brother had secretly come to the border, Liu Ziyun suspected that his purpose in coming to the border was not pure.

He secretly had some ideas in his mind, but he didn't say them out loud.

“Brother, it seems we need to get started on our plan right away,” Ruan Mumu said.

Liu Ziyun asked, "How do we change it?"

"Our sharpshooter team's training ground needs to be changed. We need to move it to the deep mountains, otherwise the noise will easily give us away," Ruan Mumu suggested.

Qiao Tinghao and Liu Ziyun exchanged a glance and nodded solemnly in agreement.

"Secondly, those who come from the military camp to participate in training are not allowed to leave here and return to the military camp at will."

"Villagers shouldn't leave the village unless necessary; it looks like war is imminent," Ruan Mumu added.

"Third, the village must take action and start digging tunnels."

As soon as Ruan Mumu said that, Qiao Tinghao understood instantly, but Liu Ziyun was completely confused.

"What do you mean by 'tunnel'? I don't understand." Liu Ziyun asked directly.

“A tunnel is a passageway dug underground, similar to the secret passages you’re talking about.”

"The tunnels were mainly dug underground to prepare for the coming war. Besides serving as refuge, they could also be used to secretly change exits and kill the enemy without anyone noticing." Qiao Tinghao saw that he looked blank and gave a simple explanation.

Liu Ziyun heard it, but still couldn't understand how this method was implemented.

Ruan Mumu and Qiao Tinghao felt that they couldn't explain it clearly in a short time, so they decided not to reveal too much for the time being.

"Girl, let's go to the village chief's house soon. We need to discuss digging the tunnel with the village chief and clan chief as soon as possible, otherwise it might be too late," Qiao Tinghao said anxiously.

Ruan Mumu knew that this matter needed to be addressed as soon as possible, so she quickly stood up, grabbed Qiao Tinghao's hand, and left.

Seeing that they ignored him, Liu Ziyun quickly followed them out.

Qiao Tinghao and Ruan Mumu each rode a motorcycle and waited for Liu Ziyun to come over in the backyard.

When the three men's motorcycles stopped in front of the village chief's house, the village chief heard the sound of the motorcycles and had his son open the gate.

When the three entered the village chief's hall, they saw that several clan leaders were already seated there.

When training ended today, Qiao Tinghao had privately sent a message home to the clan chief, asking them to gather at the village chief's house tonight to discuss important matters.

"Tinghao, Mumu, you've finally arrived." Village Chief Tian and the clan leaders all seemed to have been waiting anxiously.

Qiao Tinghao said unhurriedly, "The reason I've gathered everyone here tonight is because there's a very urgent matter I need to discuss with you all, and something that needs to be arranged immediately."

"What could be so urgent?" Chief Yang asked.

Qiao Tinghao then briefly recounted the news brought by the people who came from the military camp for training today.

"What? Are we going to war?" Village Chief Tian was shocked when he heard the news.

Although everyone had anticipated the possibility of war, since they were currently training in the two villages as a precaution in case war broke out.

"So what are we mainly doing now?" Chief Ruan asked.

Qiao Tinghao took out a piece of paper and a charcoal pencil and said, "My daughter and I both saw a book before that described a way to avoid war."

We dug underground tunnels that connected every household in the village. If we discovered an enemy attack, we would immediately enter the tunnels from the entrance.

We not only need to relocate the villagers, but also involve those who are capable in the battle to defend their homes.

"Oh...you have a specific plan, right?" Chief Ruan asked again.

Qiao Tinghao then drew a design for the tunnel on a piece of white paper, including designs for various exits and ideas for setting traps in the tunnel.

"Brilliant! How come we never thought of that?" After hearing Qiao Tinghao's plan, Village Chief Tian slapped his thigh in admiration.

The other clan leaders echoed, "Yes, absolutely brilliant!"

"This matter should not be publicized. Each of our clan leaders should go back and tell their brothers in the clan about the plan, and then go to each family in their own clan."

"Determine the tunnel plan for your own clan as soon as possible, and start digging as early as possible. Each clan will be responsible for the area within its own territory, and then the clans will connect with each other," Qiao Tinghao said again.

After a long silence, everyone agreed.

"Tomorrow, please have the clan leaders send someone to my house to collect the energy-saving light bulbs so that everyone can have light while digging the tunnel. Two energy-saving light bulbs for each household."

If the brightness is insufficient, we'll go to the clan chief's house to get a new one.

"Each clan chief's house should have one hundred replacement lamps. When half of them have been replaced, the clan chiefs should bring any lamps that are not bright enough to my house so I can replace them with new ones," Ruan Mumu said, making the arrangements.

"Great! This will make things much more convenient for everyone," Village Chief Tian said with a smile.

"If you need a hoe or shovel and you don't have enough, you can come to my house to borrow one," Ruan Mumu added again.

After all, some families have a large number of members and may not have enough tools. If they were to purchase them specifically for this purpose, they might not be able to afford the expense.

"Is the plan for Jinhe Village the same as ours?" Village Chief Tian asked tentatively.
