Speaking of birthday gifts, Mu Yao also put down the hoe in her hand and took out a dozen porcelain bottles from her storage bag with a smile: "Look, these are all the empires that Senior Sister has built over the past few months! You can pick whatever you like!"

“That’s right!”

Mu Yao picked up one of the black porcelain bottles mysteriously, opened the lid, and a medicinal fragrance wafted into her nose.

"This is a new recipe for the elixir I developed. I added a special secret ingredient to it. I've tried it. Xiaohe, look at me. Is there any difference?"

Mu Yao blinked at Sheng He.

Sheng He carefully looked Mu Yao up and down, and suddenly said in surprise: "Senior Sister, you have already reached the great perfection of foundation building!"

Mu Yao nodded heavily and poured the only pill in the porcelain bottle into Sheng He's palm.

"Yes! This elixir can actually improve your cultivation. It's a pity that the secret treasure is so rare. I have only refined these two in total. This one is for you as your birthday gift! Why don't you try it now?"

Under Mu Yao's expectant eyes, Sheng He swallowed the black pill in one gulp.

As soon as he took the pill, a familiar feeling came over him. Sheng He felt hot all over, and his chest felt like something was stuffy and about to explode.

"Xiao He, I have refined several other third-grade elixirs. You can take some too."

Mu Yao stuffed the remaining porcelain bottles into Sheng He's arms.

Sheng He shook her head vigorously, trying to keep her mind clear. She looked down at the palm of her hand.

A red feather mark appeared there.

That feather again...

The Senior Sister Mu in front of him seemed to have turned into three, the Senior Sister Yun had turned into five, and there was also a man. Who was he?

Sheng He's face flushed red. She tried her best to control herself, but she felt dizzy.

Looking at the eight or nine ferocious men and women in front of him, Sheng He stood up shakily and pulled out Ao Shuang from behind without hesitation.

"You... who are you? Where is my senior sister? You dare to hurt my senior sister, die!"

Three little carrot heads: ...Why are you here again?

Mu Yao and Yun Qianshan who were pointed at by swords:?

Yun Qianshan looked at Mu Yao with a blank look in his eyes: "Xiaoyao, is this situation normal?"

"Of course it's not normal! Why don't you run!"

But before they could dodge, Sheng He stabbed at them with his sword.

Mu Yao was horrified when she saw the sword moves Sheng He used: "No way, the eighth move of Qingyun Sword Technique! Xiaohe, why are you so cruel to Senior Sister!"

As Mu Yao spoke, she quickly pulled Yun Qianshan and Song Jinzhi behind her, and then instantly held the purple umbrella given by Sheng He in front of her.

With a "bang", Ao Shuang hit the umbrella and was bounced back heavily.

Sheng He tilted his head and looked at the purple umbrella in front of him in confusion, as if he didn't understand why a thin umbrella could block his attack.

The next moment, she raised her sword and rushed forward again.

"Xiaoyun!"

Yun Qianshan nodded and immediately took out a pipa. She was a music practitioner and was best at illusions.

As melodious music sounded, Sheng He's sword-raising movements gradually slowed down. Seeing this, Mu Yao immediately took out the spirit rope and tied Sheng He up tightly.

After being tied up by the spirit rope, the spiritual power of the cultivator's whole body will be suppressed. Looking at Sheng He who was still holding the sword and waving it in the air, the three of them breathed a sigh of relief at the same time.

Fortunately, Sheng He no longer has much killing power.

"Xiaoyao, what kind of elixir are you refining? It's too unreliable!"

Mu Yao was also a little puzzled. After taking it, she clearly felt that her whole body was full of spiritual energy, and she broke through a small realm in less than three days.

Why did Sheng He become like this after taking it?

Mu Yao quickly took out a detoxification pill and fed it into Sheng He's mouth.

Sheng He's movements were slightly slower, but the hand holding the sword was still waving.

Mu Yao frowned. It’s useless?

Isn't it poisoning?

Diemenglan, Liuguangteng, Yueyinghua... Mu Yao carefully recalled the materials needed to refine the pill, but she had used these materials before and had never encountered such a problem!

The only difference is...

Red feather bird!

The red-feathered bird only appeared a thousand years ago. According to historical records, the red-feathered bird is full of treasures, and its tail feathers are a rare medicinal ingredient.

Mu Yao had never heard of red-feathered birds in the Jingyue Secret Realm before. She encountered one by chance a few months ago and thought she was lucky. She chased the red-feathered bird for two days before she plucked the tail feather from it.

But they were clearly pills that were made together, so why did the effects after she and Sheng He took them completely different?

unless……

Mu Yao looked at Song Jinzhi with a serious expression: "Has this happened to Xiaohe before?"

Song Jinzhi recalled the scene when he first met Sheng He, and nodded quickly: "When I met Fairy Sheng five months ago, she was like this, but later she suddenly got better for some reason."

"Five months ago?"

Wasn't that exactly when she encountered Akabane?

Mu Yao was horrified. She knocked Sheng He unconscious with a palm strike and quickly searched Sheng He's body. Finally, she found a small red feather mark on the palm of Sheng He's hand.

Mu Yao's legs went limp and she fell to the ground.

"Xiao He has been poisoned by someone."

"Gu? What kind of Gu?"

Yun Qianshan helped Sheng He up and looked at the feather mark on the palm of Sheng He in confusion.

"No wonder there's a red-feathered bird here. How could such a coincidence happen in this world?"

Mu Yao murmured softly, and when she raised her head again her face was pale.

"This is the Heart-breaking Gu. When the Red Feather Bird activates the Gu, the insect will begin to gnaw at Xiao He's heart and lungs. However, due to the medicinal properties of the Red Feather Bird, Xiao He will not feel any pain, but will instead fall into a state of extreme excitement."

"Until... until... the poisonous insect ate Xiao He's internal organs clean, and then she... just..."

"It's me! I killed her!"

Mu Yao covered her face and started crying softly. Yun Qianshan looked at Sheng He in his arms, still a little bit unbelieving.

Everything was fine just now, and she even gave Sheng He a birthday gift. How did it become like this in the blink of an eye?

Suddenly, she seemed to have thought of something and quickly pulled Mu Yao to her side: "Didn't you raise a Gu when you were refining pills before?"

Yun Qianshan kept gesturing with his fingers: "It's that bottle of little black bugs, the ones you said you've been raising for over a year and that can cure all kinds of diseases!"

"Yes! Yes! That's the Gu King I raised!"

Mu Yao quickly took out a crystal clear porcelain bottle from her storage bag. The bottle was densely packed with black bugs. As soon as she opened the lid, a black bug crawled onto her finger.

Mu Yao tried to feed the little black bug on her finger carefully into Sheng He's mouth with trembling hands, but as soon as the little black bug got close to Sheng He's body, it retreated frantically as if it was afraid of something.

Mu Yao's face turned even paler. She grabbed the little black bug's body and tried to force it into Sheng He's mouth. However, as soon as the little black bug touched Sheng He's skin, its body suddenly stiffened and stopped moving.
