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

As Dr. Liu packed his things, he replied, "More than half a month."

Upon hearing this answer, Wang Dezhu and the other two were stunned.

"I didn't expect it would take so long to learn this stuff! If even doctors have to learn it for so long, then it must be even more difficult for us to learn it!" Wang Dezhu lamented.

Seeing their reactions, Dr. Liu chuckled and said, "We have to be responsible for the injured. We need to be careful with disinfection when suturing, and try to prevent the wound from getting infected. Once infected, it can easily cause a high fever."

After listening, the group remembered Doctor Liu's words.

"Dr. Liu, could you perhaps provide us with some disinfectant? We often have wounded soldiers in the military camp. If we had this, it would reduce wound infections and significantly decrease the number of deaths and injuries," Wang Dezhu asked hesitantly.

Before Dr. Liu could answer, Ruan Mumu walked in from outside, carrying a half-full glass of water, and said with a smile, "Deputy General Wang, our workshop will soon be in production."

The first batch will consist of painkillers and infection prevention pills. With the war about to begin, we need to expedite production.

Wang Dezhu and the others were very excited when they heard the news.

"That's great! This will save many of our brothers." Wang Dezhu grinned from ear to ear.

Dr. Liu took an antibiotic pill from the medicine box and handed it to Qiao Qianjiu. He also took the half-cup of water that Ruan Mumu handed him and asked Qiao Qianjiu to use it to take the pill.

In fact, Doctor Liu was reluctant to take out even a single piece of medicine. If Ruan Mumu took out the spiritual spring water and gave it to Qiao Qianjiu to drink, the wound would slowly heal. Even if he ate it, it would be a waste.

This medicine should be used sparingly, since Ruan Mumu's spiritual spring water is limited and cannot be by her side at all times.

"Now that the wound has been stitched up, Uncle Liu, Deputy General Wang, would you be interested in watching the battle?" Seeing that everything here was finished, Ruan Mumu suggested that the two of them go and watch their training.

Doctor Liu had already packed his things, glanced at Wang Dezhu, and said, "Let's go! Let's go watch the game and see how capable they are."

Wang Dezhu looked at Qiao Qianwu and said, "Qianwu, you stay here and take care of Qianjiu. We'll go check on him."

After saying that, the two followed Ruan Mumu to their training area.

Soon the group reached the mountainside. Below, the valley floor was covered with shrubs and few trees, offering a fairly open view.

Ruan Mumu handed each of them a pair of binoculars and said, "Let's look from here! There are guns and cannons down there, so we can't get close to avoid being accidentally injured."

Dr. Liu and Wang Dezhu took the binoculars and quickly put them in front of their eyes. Through the binoculars, they saw the real scene below.

The group below was large, numbering over a hundred, but their division of labor was very clear. Each group consisted of ten people, and each group had a different task and used different types of weapons.

Upon closer inspection, one can see that some groups are carrying pistols, some are carrying long-handled guns, some are carrying machine guns, and some are even carrying grenades or explosive charges...

Of course, they didn't recognize all the weapons they saw.

"Uncle Liu, Deputy General Wang, look over there. They are trying to blast open an extremely hard stone wall."

"Blowing up that stone wall is their primary objective; for now, we can treat it as a heavy city gate," Ruan Mumu explained, pointing in a direction.

Following the direction indicated by Ruan Mumu, Dr. Liu and Wang Dezhu looked and saw four people carrying something that looked like a cotton quilt, crawling on the ground, seemingly trying to get closer to a stone wall in front of them.

Behind the four men were two groups of people. One group was covered in grenades, and their expressions were tense yet resolute, as if these grenades were not deadly weapons but part of their lives.

The other team carried bombs, at least twenty bombs per person, which looked quite heavy, but they carried them with ease.

About several dozen meters away from them, a group of officers armed with police pistols were firing at the four men, sometimes aiming at their heads and sometimes at the city gate. Their purpose was clear: to provide cover for the four men.

Each gunshot rang out in response to an enemy attack, ensuring the safety of the four men.

A hundred meters away, another squad stood armed with long machine guns.

Their eyes were sharp and fixed on the upward direction, their aim being to eliminate enemies such as archers on the city walls.

Their movements were skilled and swift, each trigger pull accompanied by a deafening gunshot, giving the enemy above no chance to catch their breath.

In addition to the people providing cover, there was also a team of snipers hidden in the shadows.

Their figures were hidden high up where they were not easily spotted, their eyes as sharp as those of eagles.

Their mission was to target enemy generals and kill them with a single shot whenever the opportunity arose.

Their existence is for the purpose of "capturing the king first to catch the thief"—once the general is dealt with, the remaining underlings will only cause chaos.

As the four men drew closer to their target, even Dr. Liu and Wang Dezhu, who were observing, began to tense up.

As they approached the stone wall, the four men simultaneously placed the explosive charge in front of it. The width of the charge was roughly the same as the width of the city gate. Then, they all lit the fuse of the explosive charge at the same time.

The fuse ignited quickly, crackling and popping. Without hesitation, the four turned and fled as fast as they could to a safe area several dozen meters away.

At that moment, time seemed to freeze, and everyone held their breath, waiting for the explosive charge to detonate.

"boom......"

"boom......"

"boom......"

"boom......"

The four explosive charges detonated almost simultaneously, their deafening roar echoing through the sky, causing the birds and beasts in the canyon to scatter in terror.

At the same time, various gunshots were also mixed in, giving the entire canyon a shocking feeling.

Meanwhile, Dr. Liu and Wang Dezhu, who were watching the battle from halfway up the mountain, were also startled by the roar.

Because they had never heard such a powerful sound before.

When they looked more closely at the spot where the explosives had been placed, it was now littered with flying rocks.

"Mumu, what was that big package just now? How could it be so powerful?" Doctor Liu asked curiously.

"That was a bomb, did it scare you?" Ruan Mumu was worried that the noise had frightened the two of them.

“You little rascal, although we’ve never seen anything like this before, we’re not completely ignorant either. If you, a little girl, aren’t afraid, what are we afraid of?” Wang Dezhu laughed heartily.
