Father, who is both a heir and a descendant, is still biased; the bound system has gone berserk.

"Ying Yufu!"

The second prince roared angrily, "Release Zhi'er right now! She's fainted!"

Ying Yufu stopped, turned around, and gave the Second Prince a provocative smile.

You can't stand this?

She slapped Ying Hengzhi twice across the face, and Ying Hengzhi woke up in pain, feeling dizzy.

"My cousin didn't faint, she's awake!"

Second Prince: !

The second prince stared at Ying Yufu in shock, utterly incredulous. "Ying Yufu, how could you have become so vicious?"

Slap! Slap!

In response, Ying Yufu slapped Ying Hengzhi twice more across the face.

She looked at the Second Prince with a smile.

Am I vicious?

The second prince was about to open his mouth to rebuke her, but when he met Ying Yufu's smiling gaze, he swallowed the words he was about to say.

Ying Yufu smiled with satisfaction. "Does the Second Prince still want my mother to apologize to the First Branch?"

Second Prince: "You dare threaten me?"

Ying Yufu smiled innocently at him, while Ying Hengzhi let out a painful groan.

Ying Yufu's hand, which was gripping her hair, tightened silently.

The second prince realized that if he dared to say it, the only one who would suffer would be Zhi'er.

He said unwillingly, "I have no business in your family affairs. Release Zhi'er immediately."

"It's good that His Highness the Second Prince is aware of this; after all, even an upright official finds it difficult to settle family disputes."

As Ying Yufu spoke, she rubbed and tossed Ying Hengzhi away like trash.

"Zhi'er!"

Liu Xueyan covered her mouth and cried.

The second prince, feeling extremely distressed, stepped forward and embraced Ying Hengzhi.

But when he parted Ying Hengzhi's hair and saw her face, swollen like a pig's head, half of which was covered in blood and missing two front teeth, his movements froze for a moment.

He refused to admit that Ying Hengzhi looked terrible in this state.

He gritted his teeth, picked the person up, and quickly left to find the imperial physician.

Ying Yufu looked at Liu Xueyan, who was full of resentment, and asked, "Why isn't Aunt leaving yet? My eldest cousin is missing two front teeth."

"Alas, since ancient times, which imperial princess has ever been without front teeth?"

Liu Xueyan also thought of Ying Hengzhi's appearance just now, as well as the Second Prince's barely perceptible stiff movements.

She was experienced and understood men best; she saw the Second Prince's momentary stiffness.

She gritted her teeth and turned around, only to see the box that Shi Shu was holding in his arms.

Although Shangguan Tang's dowry was extensive, she had seen it for eighteen years. While she wouldn't say she knew it all by heart, she still remembered most of it.

She recognized the box; barring any unforeseen circumstances, it contained...

Ambergris!

A glint of shrewdness flashed in her eyes. "So my second sister-in-law has already brought back the dragon's saliva herb. If I had known this earlier, why would I have made such a fool of myself?"

Ying Yufu said, "Aunt, doesn't Father have you, his understanding and confidante?"

"Love conquers all, even water is sweet. My mother and I believe that the bond between you and your sister-in-law can withstand any hardship; you don't need any dragon's saliva herb at all!"

After saying that, they walked past Liu Xueyan and left.

[Ding! Congratulations, host, you have successfully proven someone wrong. The system rewards you with 100 points. Your current balance is 4438 points.]

……

As soon as they approached that nameless, secluded courtyard, they heard a painful howl that sounded like that of a wild beast.

The servant knelt outside and cried.

"Young master, please, don't hurt yourself! Young master, please open the door!"

Ying Yufu stepped forward and grabbed the servant boy.

Then, with a swift movement, he kicked the door open.

The servant looked at her blankly, but soon he realized what was happening and rushed into the room.

Ying Yufu and Shangguan Tang went in together, and when they saw what was inside, their faces turned pale.

Ying Zhuoxiu recklessly slammed his head against the wall, each time causing it to bleed profusely.

Blood stained not only his face but also his eyes.

"Zhuo Xiu!"

"elder brother!"

Shangguan Tang rushed forward and pulled Ying Zhuoxiu away, but Ying Zhuoxiu had lost all reason.

His hands and feet were pinned down, and he roared in pain, struggling frantically as he tried to slam his head against the wall.

"Zhuo Xiu, no, you'll die!"

Shangguan Tang was in tears, his eyes filled with endless hatred and resentment.

Why! It's your own children who are suffering like this, why?

"Little Eccentric, do you have the medicine to cure my brother?"

Ying Yufu stared intently at her brother, who was struggling in pain.

[Host, your brother isn't sick, he's been poisoned by a curse.]

He's in so much pain because someone is controlling the mother worm to torment him.

Ying Yufu's eyes widened. "You mean, someone is deliberately manipulating the mother Gu to torment my brother?"

That's right.

Ying Yufu browsed the system's shops and her gaze quickly fell on two items: Thousand Gu Guide and Gu Stone.

"Little Madman, can the Thousand Gu Inducing Agent and the Gu Stone save my brother?"

Yes, host, but there are differences between the two.

The Thousand Gu Summoning Technique can draw out the Gu Stone from your brother's body without anyone noticing and imprison it, so that even the owner of the mother Gu will not be able to detect it.

The Gu Stone can instantly kill Gu worms; the owner of the mother Gu will be instantly devoured, but the owner will also instantly know that the offspring Gu have been killed.

Ying Yufu's eyes flickered. She wished she could kill the Gu worm immediately and make the owner of the mother Gu suffer a backlash, but that would be too easy for the other party.

[Purchase the Thousand Gu Inducing Agent!]

In the end, Ying Yufu chose the Thousand Gu Inducing Technique.

[Ding! Purchase of Thousand Poisons Guide successful. 300 points deducted. Current point balance: 4138 points.]

The next moment, a palm-sized, eight-hole bronze box appeared in Ying Yufu's hand. Its antique color exuded a mysterious aura.

Ying Yufu quickly browsed the instructions for using the Thousand Gu Inducing Technique.

She glanced at her brother; her mother and the others were barely able to hold him down.

She leaped forward, locked her brother's arms behind his back, and with a kick, slammed him to the ground.

No matter how much Ying Zhuoxiu struggled, it was no use. His eyes were bloodshot and empty, like a soulless puppet. He subconsciously bit his tongue.

Ying Yufu's pupils contracted, and she gently shook the eight-hole copper box near his ear.

A soft bell rang out from inside the copper box.

Ying Zhuoxiu's pained expression suddenly eased.

Ying Yufu gently shook the Thousand Gu Inducing Flame repeatedly, and finally slowly approached, placing the Thousand Gu Inducing Flame near Ying Zhuoxiu's ear.

A small, blood-red worm slowly crawled out of Ying Zhuoxiu's ear, followed the strands of hair, and burrowed into the Thousand Gu Inducing Vessel.

Ying Zhuoxiu's pained expression gradually cleared up, like the end of a storm.

Although his eyes still retained the bloodshot marks from his previous pain, they slowly regained their clarity and brightness.

"mother!"

He looked in Shangguan Tang's direction and called out softly in a hoarse voice.

Shangguan Tang covered her mouth tightly, tears streaming down her face.

"Zhuo Xiu, Zhuo Xiu..."

"My Zhuoxiu!"

She rushed forward, wanting to pull him into her arms, but dared not touch him.

Ying Yufu stared at the Gu worms struggling wildly within the Thousand Gu Inducing Technique, a cold, bloodthirsty smile creeping across her lips.

With such a bug jumping around in his head, how could my brother not be in pain?

"Mother, brother is alright now. That Gu worm can no longer get near him."

Ying Yufu released Ying Zhuoxiu.

Ying Zhuoxiu felt a sense of relief. He blinked blankly. What had been pressing down on him wasn't a boulder, but... his sister?
