His entire family perished in battle; he rose from the ashes to conquer the world.

Gao Song grinned maliciously, his facial features contorted from the exaggerated gesture, making his smile look extremely creepy.

Upon hearing this and seeing his father's expression, Gao Yan's eyes lit up. He knew that his father must have come up with a better way to deal with Mu Yuan.

Meanwhile, Mu Yuan and his group traveled day and night, finally returning to the Xifu Army camp before dawn.

However, he had just entered the tent.

Then he saw his second sister-in-law, Su Wanqing, glaring at him angrily.

"Do you think you've grown too big for your britches? Or do you think you're too old for this world?" Su Wanqing's words carried a accusatory tone.

Mu Yuan suddenly realized that he had forgotten about the medicinal bath when he went to the Gao family yesterday, and he immediately felt a little guilty.

"Second sister-in-law, how could I dare?"

Mu Yuan gave an awkward smile, feeling neither justified nor assertive.

"The Heart-Changing and Bone-Eroding Soup must be used for daily soaking for forty-nine days before it can completely change your constitution."

Su Wanqing became increasingly angry as she spoke:

"It's only been a few days, and you've already forgotten? Do you know the consequences of abruptly stopping?"

Faced with Su Wanqing's blame, Mu Yuan had no temper. After all, it was he who asked to do it in the first place. Now that it was interrupted because of trivial matters, it was only natural for Su Wanqing to get angry.

"Second sister-in-law, it was my oversight."

At this moment, Mu Yuan didn't look like a commander-in-chief at all; he looked more like a younger brother-in-law who had made a mistake and was being scolded by his sister-in-law.

Seeing that Mu Yuan's attitude in admitting his mistake was very good, Su Wanqing's anger subsided a lot. The reason she was so angry was entirely because she cared about Mu Yuan.

If anything were to happen to Mu Yuan, the Mu family would not only be without an heir, but would also face collapse.

"Take it."

At this moment, Su Wanqing took out an exquisite little wooden box from her bosom and handed it to Mu Yuan.

"What is this?"

Mu Yuan took the box from Su Wanqing, his eyes filled with confusion.

A hint of smugness flashed across Su Wanqing's face as she said, "This is the Heart-Changing and Bone-Corroding Pill. With this, you only need to take three pills a day, and you won't have to bother with medicinal baths anymore."

Ever since Old Madam Mu urgently summoned Mu Yuan back, Mu Yuan has had to carry the medicine bucket onto the carriage.

This is really too much trouble.

Therefore, Su Wanqing began to study how to make things more convenient.

In recent days, she has read through ancient medical books and, based on her medical knowledge, developed the "Heart-Changing and Bone-Eroding Pill".

The Heart-Changing and Bone-Eroding Pills eliminate the need for cumbersome medicinal baths. Simply take three pills, and once they enter the body and the medicine spreads, they will take effect.

In addition, Huanxin Shigu Wan differs from Huanxin Shigu Tang in one aspect.

That is the Heart-Changing and Bone-Corroding Soup, which causes unbearable suffering during the soaking process due to its potent and overpowering ingredients.

The effects of the Heart-Changing and Bone-Corroding Pills are much milder.

Not only will you not suffer, but you only need to take three pills a day to have the same effect as soaking in a heart-changing, bone-eroding soup for several hours.

Mu Yuan's eyes lit up, and he immediately praised Su Wanqing:

"Second sister-in-law's medical skills are amazing, I admire her greatly."

"This box contains a seven-day supply. I'll bring it to you again in seven days," Su Wanqing instructed earnestly.

Mu Yuan nodded repeatedly and said:

"I will always remember my sister-in-law's great kindness and virtue."

He has been preoccupied with various affairs and has to endure the torment of the effects of the Heart-Changing and Bone-Corroding Soup every night.

Furthermore, in case of an emergency requiring them to go out...

He also had to carry a large medicine tub, which was extremely troublesome.

The situation is completely different now.

His second sister-in-law, Su Wanqing, developed a portable "Heart-Changing and Bone-Corroding Pill." Even if he needed to go out in an emergency, he only needed to bring the medicine box to set off immediately.

It greatly eliminates tedious steps.

Mu Yuan opened the box, grabbed three pills, and without even examining them closely, popped them into his mouth and began to chew.

The strong medicinal taste exploded in my mouth, mixed with bitterness.

Mu Yuan's facial features instantly contorted.

However, after chewing a few times, Mu Yuan was amazed to find that the bitterness had disappeared, replaced by a slightly sweet aftertaste.

Swallow the chewed pills.

Not long after.

The medicine gradually took effect.

Mu Yuan felt a burning heat all over his body, as if a million insects were crawling all over him, but strangely, he felt no pain.

This strange phenomenon lasted only for the time it takes to drink a cup of tea.

"How is it?" Su Wanqing asked.

"I feel completely refreshed," Mu Yuan exclaimed in amazement.

"It seems it really worked." Su Wanqing breathed a long sigh of relief.

Upon hearing this, Mu Yuan raised an eyebrow, and said with a wry smile, "Second sister-in-law, are you using me as a test subject for your medicine?"

Su Wanqing blushed, realizing she had blurted out something unintentionally. She immediately gave a guilty smile.

"The situation is urgent, and I had no choice but to do this. You go ahead with your work, I'll be going now."

After saying that, Su Wanqing quickly fled the place.

Watching Su Wanqing's comical escape, Mu Yuan couldn't help but laugh.

The following days.

Mu Yuan lived a very peaceful life.

He took three Heart-Changing and Bone-Corroding Pills every day and trained with the soldiers.

In the evening, he began to instruct the Shadow Squad on some tactics.

These tactics involve how to silently send signals to other team members using hand gestures during the mission.

As the days went by.

Soon, the day arrived for the bet he had agreed to with Sun Yang.

Previously, Mu Yuan formed the Shadow Squad, selecting talents from under the command of various commanders.

Sun Yang, among others, had strong opinions about this.

Therefore, Mu Yuan made a bet with the other party, and the two sides would compete in ten days.

"General, my Tiger Flower Army is ready. Where is the squad you are training?" Sun Yang asked Mu Yuan early in the morning, his voice brimming with eagerness.

Seeing his impatient expression, Mu Yuan said slowly and deliberately:

"It seems Commander Sun has been waiting impatiently for a long time."

"I just wanted to see just how powerful the squad that the commander-in-chief trained really was." Sun Yang said he wanted to see how powerful the Shadow Squad was, but deep down he didn't take them seriously.

Sensing the disdain in his words, Mu Yuan was not angry at all; on the contrary, he felt that his chances of winning had increased considerably.

Sun Yang was so arrogant, and his words were full of contempt. Such people often end up losing because of their excessive pride.

"Before midnight tonight, my squad will launch a surprise attack on your Tiger Flower Army and capture you alive. Once you are captured and brought before me, it will be my victory. What do you say?"

Mu Yuan explained the rules of the bet.

Upon hearing this, Sun Yang burst into laughter and said:

"A surprise attack on my 5,000 Tiger Flower Army soldiers? And you even want to capture me alive? Commander, aren't you being far too presumptuous? If I may be so bold as to ask, how many men does Commander intend to send this time?"

"Less than twenty people!" Mu Yuan replied calmly.

The other commanders present looked at each other in disbelief.

Less than twenty people against five thousand?
