In the morning, the birds were still singing.

After a night of research and refinement, she finally managed to brew her first antidote!

The girl in front of him was clearly very tired, but her face was filled with dazzling light. Especially her curved eyebrows, it made people happy just by looking at her.

Bai Su rushed to the side of the bed, looked at the medicine bowl, and hesitated: "I have never tried this medicine on anyone before … He didn't know if there were any side effects. Why don't we have someone give it a try first … Hey! Mu Ling Feng, what are you doing? "

Before she could finish, Mu Ling Feng took the medicine bowl in her hands and brought it to her mouth. Without saying a word, he held his breath, raised his head and drank all the medicine in the bowl.

"Why are you …" Bai Su pointed at him in shock.

"Isn't there no one who has tried the medicine? Then what's wrong with This King testing the medicine with his own body? "

"..."

Bai Su looked at him, dumbstruck, not knowing how to express his current feelings.

A dignified Prince of a nation actually used his flesh and blood as a bed to test medicine, he was willing to become a white mouse.

Aren't you afraid that she will poison him?

After Mu Ling Feng finished drinking the medicine, she returned the empty bowl to her and pursed her lips.

"Pfft!" Bai Su was amused by him, "I already said that no one has tried to use the medicine before, if anything happens to you, don't blame me."

Mu Ling Feng laughed, and did not say a word.

Bai Su looked at him, and a faint smile blossomed on his face.

In the morning sunlight, she was as beautiful as an angel.

Mu Ling Feng stared blankly, unable to recover from her shock for a long time.

Suddenly, he clutched his stomach and exclaimed, "Hiss — ah!"

"What's the matter with you?" Bai Su stopped laughing, and anxiously bent over, pulling his arm, her eyebrows knitted tightly.

Mu Ling Feng was in so much pain that she couldn't even straighten her waist.

Bai Su panicked, and spun in place: "How could it be … How could this be? I clearly have a pair of drugs on me … Mu Ling Feng, tell me, where are you feeling uncomfortable? "

Her voice was hoarse and faintly tinged with tears.

Mu Ling Feng's body stiffened. She straightened her back and looked at her, her face showing no signs of pain.

"I'm fine, don't cry." He had only been joking with her, but she had nearly cried for him.

Bai Su was startled.

"You lied to me?" Her eyes turned red, she raised her fist and started beating Mu Ling Feng up, "You are too despicable!"

Although he was not completely cured, and his body was still very weak, Mu Ling Feng still did not move, allowing her fists to vent on him.

In the past few days, he had watched too clearly from the side how much trouble Bai Su had gone through and how tense his mental state was.

It was precisely because of this that his heart ached.

After venting for a bit, Bai Su's movements became slower and slower, and gradually stopped.

Mu Ling Feng caught her hand and looked at her face.

The little face that was full of makeup was full of tears. Looking at it made his heart ache for no reason.

Bai Su lifted his head. Facing Mu Ling Feng's gaze, the calm gaze seemed to have changed a little.

Mu Ling Feng reached out her hands, wanting to help her wipe away the tears on her face.

Bai Su suddenly turned his head and took two steps back: "Prince, please have some self-respect."

Mu Ling Feng's face froze, she extended his hand into the air and forgot to retract it.

"Prince." Bai Su looked at him, his expression as respectful as ever, "Since you've confirmed that there's nothing wrong with that medicine using it, then I'll go and prepare the medicine for the other patients."

She did not stop, staring at Mu Ling Feng, she retreated two steps, then turned and walked out the door.

"Wait." Mu Ling Feng suddenly called out to her, "In your heart, am I like those other patients, who are only your patients, so you treat me well?"

In the past two days while he was infected, Bai Su had treated him so well that he had almost forgotten about the discord between the two of them.

Bai Su stopped and turned back. He moved his lips and said lightly, "Yes."

After which, he didn't linger and walked out.

Mu Ling Feng looked out of the window at the sky, looking lonely.

After Mu Ling Feng investigated, she quickly found the source of the poison.

Unfortunately, before he could even interrogate him, he had shattered the pill hidden under his tongue and poisoned himself.

Bai Su and Mu Ling Feng both knew that this matter was not that simple. There was definitely another mysterious person controlling them from the shadows.

But who in the world could be so resourceful?

When everyone had retreated, Bai Su opened the dead man's collar and pointed to a mark on the back of his neck. "Do you recognize this pattern?"

Mu Ling Feng looked carefully and muttered: "I seem to have seen it somewhere before …" Suddenly, his eyes lit up, "Xicheng!"

"Xicheng?"

"Yes." This King had gone to the Xicheng with Fourth Brother long ago and had seen this pattern before.

Bai Su seemed to have thought of something, "The plague became worse after Second Prince left, could it be …"

"For now, I can't make wild guesses." Mu Ling Feng said, "We have no evidence."

"Yes."

The plague in Mudu was finally under control.

Bei Mu Huang ordered three Prince s to send Xicheng Qin Yin and seven Princess s out of Bei Mu safely. Only then did he heave a sigh of relief, when news came from the south — — The situation was dire, Idle King's life was hanging by a thread!

Bei Mu Huang immediately ordered the King Jin couple to head south to help the Idle King.

As the situation was grim, Bai Su set off first, with Mu Ling Feng following closely behind to deliver the emergency medicine.

Three days later, Bai Su arrived at the Wucheng where he was.

The location of the Wucheng was extremely dangerous. On one side, it was right next to the southern part of the Xicheng, while the other side was directly to the southern part of the Ling-Tian Empire.

Convenient transportation and developed economy. At the same time, the mountain forest here was extremely steep. Rivers intersected each other, making it easy to defend and attack.

It could be said that the Wucheng was not only a transportation hub for Beimu Kingdom to different countries, it was also a very important military base.

Bai Su had just arrived at the Wucheng, and before he even entered the city gates, he saw a city in ruins, and the citizens were not in a good mood.

The streets were littered with dead or dying people, those who were sound enough to be running about, some running to the gates in panic, trying to get out.

"Let us out! We are going out! "

"We don't want to die here! Quick, let us out! "

The guards circled and circled, indifferent to their shouts.

Bai Su noticed that among the guards, there were also some that had pale faces and dark yellow bodies. They had no strength to stand, as if they would collapse at any time. Clearly, they also had signs of infection.

In the entire Wucheng, where could there be such a prosperous side of things?

This place was basically a dead city.

Since the Wucheng had become like this, why didn't Mu Yun Tian care?

Bai Su suddenly had a bad feeling about this.
