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

"This explosive charge is so powerful, I wonder how many of these explosive charges you have, Mumu?" Dr. Liu asked curiously.

Ruan Mumu lowered her voice and said, "Although I don't have it at the moment, I can have it if I want to, but I can't say that. I'm still somewhat useful now that we're preparing to fight the Western Rong, but if we conquer the Western Rong, I might become a great threat in the Emperor's eyes."

Dr. Liu and Wang Dezhu nodded in agreement with Ruan Mumu's words.

They knew in their hearts that emperors had always been suspicious and would never allow any potential danger to exist.

If the Emperor knew that Ruan Mumu could produce so many powerful items, he would probably make her disappear from the world without hesitation once she lost her usefulness.

"Deputy General Wang, when you get back, remember to tell your general not to report her matter to the Emperor, otherwise Mu Mu might even lose her life," Doctor Liu solemnly instructed.

Wang Dezhu replied solemnly, "Alright, Doctor Liu, I will definitely pass on the message. Please rest assured, I will definitely convey it to our general, and this matter must be kept secret."

He knew that this matter concerned Ruan Mumu's safety, so his attitude was firm and decisive.

After the drill, the soldiers returned to their camp to rest.

Ruan Mumu also returned to the camp with Doctor Liu and Wang Dezhu.

"Uncle Liu, Vice General Wang, you're here!" Qiao Tinghao greeted them loudly as he watched them walk back from afar.

Doctor Liu and Wang Dezhu nodded slightly at Qiao Tinghao.

"Father, why did you come up the mountain today?" Liu Ziyun asked Doctor Liu.

“Someone was injured. Tinghao sent someone down the mountain to inform me, so I came up here,” Doctor Liu replied.

The group went into the meeting tent and sat down.

This tent is similar to a Mongolian yurt, and it was specially prepared by Ruan Mumu's older brother.

"Deputy General Wang, why have you come in person today?" Liu Ziyun was quite surprised to see Wang Dezhu arrive so suddenly.

Wang Dezhu took a deep breath and then briefly told Qiao Tinghao and Liu Ziyun about the Second Prince's private conversation with Deputy General Ma after arriving at the military camp.

"Hmph, that idiot has no ability whatsoever, yet he dares to try and steal military merits. How laughable." After hearing this, Liu Ziyun revealed a disdainful sneer on his face.

"How are you all feeling about your practice? Today is already October 14th, and there are only half a month left until the second day of the eleventh lunar month," Doctor Liu asked with concern.

Mentioning practice, Liu Ziyun immediately perked up: "Dad, I've tried all the weapons here, they're amazing! And I feel like my marksmanship and grenade throwing are pretty accurate now, I have to be the vanguard."

He said smugly, his eyes gleaming with confidence.

After hearing this, Dr. Liu did not answer directly, but remained silent for a long time.

“Young Master Liu, you shouldn’t get involved in this. The battlefield isn’t a suitable place for you. You just need to stay behind and oversee things,” Wang Dezhu interjected, his tone tinged with worry.

Upon hearing this, Liu Ziyun frowned slightly and said with displeasure, "I train so hard and strive to improve myself so that one day I can personally go to the battlefield to fight bravely and protect the peace of the people of Beisheng. How can you leave me behind?"

With General Qiao and Vice General Wang both here, things are more than manageable. Besides, some people wouldn't allow me to stay in the rear with peace of mind, would they?

Upon hearing Liu Ziyun's words, Wang Dezhu couldn't help but nod in agreement, for it was indeed as he had said.

So he replied, "Yes, what Young Master Liu said makes sense."

"Deputy General Wang, you must remember this: whatever you do, don't let that person know I'm here! Otherwise, who knows what he might do?" Liu Ziyun warned anxiously.

Wang Dezhu quickly assured him, "Please rest assured, Young Master Liu, your father has already instructed his subordinates not to reveal your whereabouts, nor will he disclose a single word about your father's identity."

Liu Ziyun nodded in satisfaction.

"Deputy General Wang, please tell my father that everything is proceeding according to plan and is going smoothly, so he doesn't need to worry."

"When the time is right, I will personally lead the troops into battle and will absolutely not give the Western Rong any chance to retaliate." Although Qiao Tinghao's face was still somewhat youthful, he exuded a composure and determination beyond his years.

"Don't worry, young general," Wang Dezhu said confidently.

"Tinghao, didn't you say there was some cannon? Why haven't we seen it today?" Doctor Liu suddenly asked curiously.

Qiao Tinghao replied, "We didn't schedule any practice for this today because it allows for shooting at a relatively long distance. We only practice it every few days, so you've come at an inopportune time."

However, everyone has basically grasped the essentials, so there's no need for too much practice or wasting too many resources.

Doctor Liu nodded knowingly: "I see!"

"Young General, I also want to see the power of that cannon, so I can explain it to you when I get back, and see if I can..." Wang Dezhu said with great interest.

They didn't demonstrate this cannon when they were on the mountaintop last time, so Wang Dezhu was eager to see it today.

"Brother, since that's the case, why don't you go and show it off!" Ruan Mumu interjected from the side.

"Deputy General Wang, come on, let me show you." Liu Ziyun said, then got up and walked outside.

"Uncle Liu, let's go take a look too!" Ruan Mumu called on Doctor Liu to go and see as well.

So the group began to head into the mountains.

Liu Ziyun went to the armory to collect a cannon.

Because the cannon was quite heavy, it had a pusher, and two people kindly stepped forward to help push it down the mountain.

"Thank you so much, Brother Lei, thank you so much, Brother Meng." Liu Ziyun was very grateful for their kindness and quickly expressed his thanks.

The two men who helped push the cannon were named Lei Dashui and Meng Hai, and they were in the same group as Liu Ziyun.

These two usually volunteer to do any hard work, and Liu Ziyun has a good relationship with them.

When they arrived at their usual training location, Ruan Mumu and the others had been waiting for quite a while.

Liu Ziyun didn't say much, but quickly fixed the cannon in place and carefully adjusted its direction.

Then he said to Doctor Liu and Deputy General Wang, "Father, Deputy General Wang, you two better watch out! This time, the target is the third big tree below, and I'm going to hit the root of the tree."

Liu Ziyun clearly explained his objective to them. The people present picked up the binoculars hanging around their necks and stared intently at Liu Ziyun, waiting for his next move.

Liu Ziyun aimed again, and after ensuring the angle was accurate, he pushed the lever to engage the gear.

A deafening roar, like a thunderclap, echoed throughout the surroundings.

Everyone's eyes followed the sound and saw that the big tree that Liu Ziyun had mentioned earlier had suddenly collapsed. The place where the tree's roots had been was now a deep pit, surrounded by a mess of sand and gravel.

Dr. Liu slowly lowered his binoculars, a satisfied smile spreading across his face. He then patted Liu Ziyun on the shoulder and praised, "Good lad, your aim is really good!"

Hearing Doctor Liu's praise, Liu Ziyun was filled with pride and satisfaction.

He looked at Dr. Liu with a smug look on his face, his eyes gleaming with confidence, hoping to receive more praise from Dr. Liu.
