At 100 years old, he joined the army in place of his granddaughter, and became a national war god.

Su Mu knew that the person who reminded him was the chivalrous swordsman he had met on East Street that day.

Su Mu burned the note over the candle flame.

Just as he was about to lie down, the system's voice came into his mind.

[Ding! Side quest has been issued. Please check it promptly!]

Su Mu was pleasantly surprised. A side quest was coming at this time?

What could it be?

So he sank into his consciousness and opened the taskbar.

Side Quest: Get involved and eliminate Tuoba Han's Thirteen Black Cloud Envoys!

[Mission Rewards: 3 years of reverse aging, 100 days of lifespan, and max-level Dugu Nine Swords!]

Su Mu's pupils suddenly contracted, quite surprised.

To get involved personally?

However, for Su Mu, this was a double blessing.

First, the Thirteen Envoys of Black Cloud delivered themselves to his doorstep, saving him the trouble of searching for them.

Secondly, the system's rewards include three years of reverse aging, one hundred days of lifespan, and the Dugu Nine Swords set.

Su Mu's lips slowly curled up into a smile.

The Nine Swords of Dugu.

That's a peerless sword technique from Jin Yong's martial arts novels, which emphasizes "no moves are better than moves," becoming stronger when facing stronger opponents and breaking all martial arts techniques in the world.

On the battlefield, he could sweep through thousands of troops with the Five Tigers Severing Gate Saber and the Overlord Spear; in the martial world, he could deal with those elusive assassins with the Nine Swords of Dugu.

"Receive the mission." Su Mu's voice was hoarse, but his tone was calm.

[Ding! Host has accepted the side quest: Enter the fray and slay the Thirteen Envoys of Black Cloud!]

[Task deadline: Seven days. If not completed within the deadline, the task will automatically fail.]

Seven days is enough.

Just as Su Mu was about to exit the system, the notification sound rang again.

[Ding! Host has one completed reward that has not yet been claimed. Please check it promptly!]

Su Mu paused for a moment, then remembered that he had already completed the previous side quest, "Building a Special Operations Force for the Cold Weapon Era," and had not yet claimed the reward.

"receive."

[Ding! Congratulations, host, for completing the side quest: Build a special operations force for the era of cold weapons!]

[Rewards: 3 years of reverse aging, 100 days of lifespan, and a set of Xuan Iron Armor!]

A burst of golden light appeared in the consciousness space. After the light dissipated, a suit of jet-black armor floated in mid-air.

The armor was jet black and shiny, with a faint blue luster, like the color of millennia-old ice under the moonlight.

The gaps between the plates are so fine that they are almost invisible, forming a seamless whole, forged from a single piece of extraterrestrial meteorite iron.

The armor's surface was devoid of any decoration or patterns, possessing only an extremely simple and weighty feel.

Su Mu reached out, and the moment his withered fingers touched the armor, a cool and steady aura surged into his body from his fingertips.

He clicked on the description of the Xuan Tie Armor.

[Mysterious Iron Armor: Forged from a mixture of extraterrestrial cold crystals and meteorite mysterious iron, the armor is a seamless, impenetrable suit of armor, impervious to swords and spears, and unharmed by sharp blades. It can withstand heavy blows without damaging its inner structure, providing stable and powerful protection.]

Su Mu was very satisfied with the armor.

It is impervious to swords and spears, and unaffected by sharp blades.

From now on, he can charge into battle more recklessly without worrying about being attacked from the shadows.

He logged out of the system, opened his eyes, and returned to the real world.

Su Mu stood up, walked to the window, and opened it.

A night breeze blew in, carrying a chill.

He gazed at the night outside the window, his eyes deep and unfathomable, his brows furrowed as he fell into deep thought.

To get involved personally.

How does one enter the Dharma?

Waiting in the government office is too passive.

Moreover, those assassins weren't fools; they wouldn't make a move in a heavily guarded government office.

He had to give them a chance, a chance that seemed foolproof and once in a lifetime to them.

Su Mu's eyes lit up as he suddenly came up with a plan.

That means going out of town to hunt.

Choose a secluded place with few people, where it is easy to ambush.

He didn't have many people with him, and they seemed to be lax in their precautions.

Those assassins would definitely see this as a golden opportunity and wouldn't be able to resist making their move.

Okay, let's do it this way...

Su Mu stood up, put on his outer robe, and went out the door.

……

In the backyard, You Zhongyi was practicing his marksmanship.

Under the moonlight, the spear pierced the air with a whooshing sound, sending wood chips flying.

Under Su Mu's guidance, his marksmanship improved many times over compared to when he was in Qingfeng Village. Every thrust was clean and crisp, without any hesitation.

"Loyalty and righteousness." Su Mu's voice came from behind.

You Zhongyi holstered his gun, turned around, clasped his hands in a fist salute, and said, "Old Su, it's so late, aren't you resting yet?"

Su Mu walked up to him, looked at him, and said in a calm tone, "There's something I need you to do."

You Zhongyi asked, "Please give your instructions, Elder Su."

"Tomorrow, I will go out of town to hunt."

"It's just the three of us, along with Changfeng and Tieniu."

You Zhongyi was stunned.

"Old Su, why did you suddenly decide to go hunting outside the city?"

Su Mu raised his hand, interrupting him.

Then, Su Mu told You Zhongyi his whole plan.

After hearing Su Mu's words, You Zhongyi finally felt relieved.

"Elder Su, I understand." You Zhongyi clasped his hands in a fist salute, his eyes full of admiration. "I will make the arrangements right away. Tomorrow morning, the brothers of the special forces will leave the city ahead of time and lie in ambush in the mountains and forests in the eastern suburbs. As long as the Thirteen Envoys of Black Cloud dare to show themselves, I guarantee that none of them will escape."

Su Mu nodded and patted You Zhongyi's shoulder with his withered hand.

"Remember, don't alert them. Wait for my signal. Don't move until I do."

"yes!"

You Zhongyi turned and strode away, his steps steady and without the slightest hesitation.

……

The next morning, just as dawn was breaking.

Su Mu changed into a light and practical outfit, tied his white hair behind his head, held the Dragon Slayer Sword in his hand, and carried a bow and arrows on his back. He then mounted the Ferghana horse.

Gu Changfeng and Zhao Tieniu were already waiting at the entrance of the government office. Both of them were dressed in close-fitting clothes, with long swords at their waists and quivers and food bags hanging on their horses.

"Old Su, where are we going hunting today?" Zhao Tieniu grinned, his big, round eyes brimming with excitement. "I heard there are wild deer and roe deer in the mountains in the eastern suburbs; the meat is so tender!"

Su Mu smiled, spurred his horse, and the Akhal-Teke steed strode off towards the east gate.

"Then let's go to the eastern suburbs."

Gu Changfeng and Zhao Tieniu followed closely behind, the three horses moving slowly through the morning mist, one in front and two behind.

The horses' hooves clattered on the bluestone pavement, making a crisp "clatter" sound that was especially clear in the quiet morning.

At the city gate, the morning mist was even thicker.

When the soldiers guarding the city saw Su Mu, they quickly saluted and opened the city gate.

The suspension bridge creaked and fell to the opposite bank of the moat, kicking up a cloud of dust.

Su Mu and his two companions rode across the suspension bridge and then headed towards the eastern suburbs.

At the city gate, a man wearing a straw hat, dressed in black, with a long sword at his waist and a veil covering his face, was watching all of this.

It was the same mysterious person who had been following him in the alley yesterday.

The man in black leaned against the city wall, arms crossed, his straw hat pulled low, obscuring his expression.

He watched Su Mu's figure disappear into the morning mist, his heart filled with confusion and shock.

Is this old man crazy?

The Thirteen Envoys of Black Cloud have already been dispatched. Instead of sending more people to protect him, he took two people out of the city to hunt.

Isn't this just suicide?

Or is it that he is not afraid of the terrifying power of the Thirteen Black Cloud Envoys at all?

The man in black shook his head, lightly touched the ground with his toes, and followed silently like a falling leaf.

He knew that whatever Su Mu was up to, he had to go and see.

In the morning mist, three horses led the way.

A dark figure followed behind, heading towards the mountains and forests in the eastern suburbs, gradually disappearing into the distance.
