During the Republic of China era, I achieved unparalleled success by returning to the past.

The four men raised their axes high, the blades gleaming coldly.

Song Beiyou's aura changed suddenly, becoming as sharp as a drawn blade. With a burst of power from her feet, her petite body leaped out like a cheetah.

In a flash, he collided with the four men, drawing his sword with both hands simultaneously. The sword flashed coldly, as fast as a shooting star—forward thrust, sheathing, turning thrust! Thud thud thud thud! The movements were almost seamless, flowing smoothly and without any hesitation.

Blood spurted onto the dark teak wafts on both sides, flowing slowly downwards.

Rat-a-tat-tat...! Two axe-wielding thugs rushed from the depths of the corridor, their fat faces jiggling.

Song Beiyou's momentum showed no signs of slowing down. He suddenly leaped up, flashing between the two men. At the same time, he reached out with both hands, and two thin beams of light appeared on his waist. They flashed diagonally across the necks of the two men, then flowed back to his waist like water.

He landed on his feet and continued forward without stopping. Two breaths later, he heard a dull thud behind him as something heavy fell to the ground, followed by the hissing sound of blood splattering.

In that short time, he had killed seven people. But the shouts of battle still alerted those inside the house.

At the end of the east corridor, the door suddenly opened, and two burly foreign men rushed out, raised their pistols, turned them around, and fired, bang bang!

Almost simultaneously, Song Beiyou activated Autumn Cicada's Premonition, channeling his energy into his feet, bending over and dodging to the side, slashing his thigh with his hand, and raising his hand to retaliate with two spears.

A scorching heat swept over his shoulders and ribs, burning Song Beiyou even through his clothes. Only when his feet touched the smooth marble surface and he regained his footing did he realize that his back was covered in a cold sweat.

Looking up at the opposite side, bullets had entered the eye sockets of both men, and they had already fallen to the ground.

Song Beiyou adjusted his breathing, calmed his turbulent blood, slowed his pace, took out several smoke bombs the size of pigeon eggs from his suit pocket, and tossed them behind him. Bang bang bang bang, the corridor was quickly enveloped in smoke.

As they approached the door, they saw the corpses of two burly men lying across the room, blood gushing from their eye sockets.

Inside, at a mahogany table, a foreigner wearing a top hat put down his teacup, shook his head, and said, "Oh, Boss Zhang, how could you be so careless, causing me to lose two of my men."

Zhang Dabao remained as steady as a mountain, chuckling, "Mr. Smith, those who can be killed by a pistol are all mediocre. You should have replaced them long ago."

Smith shrugged. "Well, maybe you're right. I've had my hated those two for ages."

Song Beiyou's gun barrel twitched between the two men as he lowered his voice: "Mr. Zhang, and Mr. Smith, hand over the serum."

"Hmph!" The red scar on Zhang Tianbao's face twitched, and he suddenly stood up, like a tiger awakening. He grabbed the edge of the table with one hand and flipped it over, causing the heavy mahogany table to spring up violently.

With a shout of "Ha!", he swung his arm and smashed the huge table to pieces. The wood shards rained down like arrows.

Powerful! Song Beiyou's pupils contracted sharply. Qiu Chan sensed it first and quickly calculated the trajectory. He twisted his wrist repeatedly, and the muzzle of the gun leaped out of the gun, bang bang!

Zhang Tianbao's forward leap faltered, his upper body swayed, dodging two bullets, but his attack was immediately halted.

At the same time! Song Beiyou used his leaping technique again, the sparrow stepping on the branch, as if moving horizontally in mid-air, dodging the flying wood fragments, and said:

"Boss Zhang, you've got some skill! Don't rush into action. Take a look out the window."

Bang! Crash! Shards of glass flew everywhere from the floor-to-ceiling window.

Zhang Dabao turned around, his expression changing drastically: "Jia Cai!"

Juan stood outside the arched French windows, suspended by a rope. In the net bag around her neck sat her one-month-old baby. The little one, oblivious to fear, puffed out his cheeks and squinted into crescent moons.

"Mr. Zhang, please don't move. Otherwise, if I let go, he will fall. This is the sixth floor," Juan said with a smile.

Zhang Dabao stared at his beloved son, his shoulders slumped, his clenched fists slowly relaxed, and he asked in a deep voice, "What do you want?"

"Hand over the serum, and we'll return your son to you. You can buy more serum, but you can only have one son. It's not easy to have a child in your old age, Mr. Zhang, do you agree with what I'm saying?" Song Beiyou said calmly, standing at the door.

Just then, Juan called out from outside the window, "Little Bao, quickly call your father to save you!"

The child clapped his hands and cried out, "Ah-ya, ah-ya!"

Seeing his son's adorable appearance, Zhang Dabao's sharp gaze slowly softened, turning into tenderness. "Alright, release him, and I promise to give you the serum."

"Oh, Mr. Zhang, so you mean we've successfully completed the transaction, right?" the foreigner sitting to the side asked.

"Mr. Smith, five hundred documents will be delivered to the dock soon."

"Alright, then it's a deal." Smith's deep-set brown eyes darted around as he handed over the small silver leather case beside him.

Zhang Tianbao took it, looked out the window, and shouted, "Release the person, and I'll hand it over to you."

Song Beiyou shook his head: "Please have Mr. Zhang throw the serum over here first."

Zhang Dabao was also a shrewd and ambitious man. Knowing that entanglement would be pointless, he flicked his wrist and threw the suitcase over.

Song Beiyou caught it, slowly opened the suitcase, and glanced inside. A tube of brighter orange liquid, like a living thing, was stored in a metal container.

"Give the son back to Mr. Zhang."

Outside the window, Ah Juan took off her net and laughed, "Mr. Zhang, you'd better catch it! Don't blame me if it gets hurt." With that, she tossed the child into the house.

Zhang Dabao, who resembled a fat toad, leaped forward, and Mingkong caught his son, holding him tightly in his arms.

Song Beiyou threw out two more smoke bombs, and the corridor was already filled with white smoke. He immediately slipped into the smoke.

Some VIPs, invited by Zhang Dabao to start a card game, were frantically making their way down the corridor into the stairwell, trying to escape. Song Beiyou mingled among them, but when he reached the fifth floor, he turned around and slipped inside unnoticed through the corridor door.

He went to all this trouble, but he didn't intend to give the serum to any old lady.

The fifth and sixth floors were the same. Song Beiyou, like a nimble raccoon, moved lightly and silently to find 507. He listened for any sounds, turned the handle, and confirmed that it was empty.

The door had a brass pin tumbler lock. He pulled two brass wires from his suit lining, inserted them into the keyhole, fiddled with them for a moment, then turned and pulled. With a click, the lock opened.

Song Beiyou looked around warily before slipping inside and locking the door behind him.

The room was spacious, with a soft couch paired with a rosewood dressing table, warm light from crystal wall lamps, the gentle chiming of floor clocks, and a subtle fragrance—exquisite in every detail. It was exactly the same as room 507 three days later.

Three days later, his true form is in this room! As long as the serum is hidden in this room, he can retrieve it upon returning after completing the mission. Finally, his gaze settled on the chandelier above his head.

He opened the silver leather case and took out a metal cylinder about a foot in size. On the cool metal exterior were engraved the words: Crimson Shark, One Round, Extremely Rare.

Just then, the Book of Impermanence flew out on its own, opened the first page, the water mirror page trembled, and an invisible wolf-hair brush drew out a rusty iron tip:

[By injecting the Qianyuan-type serum, you will be immune to all adverse effects. The mutation will be absorbed by the "Inheritance of Qianyuan" mask and converted into Awakening Points.]

Song Beiyou paused, his gaze fixed on those lines of text, his heart pounding wildly. Injecting the serum not only had no side effects, but it could actually increase awakening level!

What a great thing! It seems that taking the serum for themselves was a brilliant move!
