Liu Zian was too lazy to look at him and continued to explain:

"Brother, the reason why this poison is called Biwingbird is because it is collected from a kind of exotic overseas birds that are divided into male and female. It is made from the colorful wings on their tails.

"Among them, the male bird's tail feathers are red, and the female bird's tail feathers are blue. So two bottles of poison, yang and yin, were made respectively.

"This Yang poison and Yin poison, if you only take one of them separately, there is no harm. The toxicity is latent and slowly passes away. It will not have any impact on the human body. It will not hinder the movement of the Qi practitioner's spiritual energy. It is very hidden.

"In other words, if you take one of them alone and look at it, it is not poisonous at all. However, once it is infected with the two poisons of yin and yang in a short period of time, it will be like a piece of firewood meeting a raging fire.

"Even a Qi practitioner with great supernatural powers will immediately bleed from his orifices if he doesn't use a large amount of spiritual energy to detoxify for a few breaths. It's difficult for gods to save him, let alone a mortal without spiritual energy cultivation.

"So, the wonderful thing about this winged bird is that it can poison people unconsciously without knowing it, and it can delay the onset of poison. As long as it is used properly, by the time the poisoned person reacts, there is no way to save him.

"Looking at the strange poisons in the world, Biyiniao can also be ranked first."

Liu Zian withdrew his gaze and said, "These are what my good friend told me back then."

"Oh? It's really so magical."

Liu Ziwen looked very interested and looked down at the two ordinary white porcelain vials in his hands.

Liu Zian looked at his elder brother's expression, turned his eyes and thought for a moment, then he suggested:

"Brother, there are differences in the way of taking the Yang poison and the Yin poison of Biyiniao.

"The poison in the green bottle is colorless and odorless, and is very hidden. It needs to be taken into the body orally, or it can be infected through wounds.

"The Yang Po in the red bottle has a fragrant fragrance that is as light as sweet-scented osmanthus. It is suitable for sniffing. You only need to open the bottle and wait for a while, and it will spread throughout half of the hall.

"And those who have been infected with sinister poison before, smelling this fragrance, can be poisoned within ten breaths...

"Brother, it's better not to try to open it now. Don't let us get infected. It will be quite troublesome to dissipate naturally."

Liu Ziwen nodded and chuckled, "Interesting."

Liu Zian pondered: "I haven't asked yet, what is the use of this poison?"

Liu Ziwen glanced at his second and third brothers and spoke concisely:

"in case."

Liu Zian looked at the two small white porcelain bottles that Liu Ziwen put into his arms gently and carefully, with a thoughtful look on his face.

Seemingly realizing that it was probably related to what was about to happen tomorrow, Liu Zian and Liu Zilin tacitly agreed not to ask further questions.

Liu Ziwen put away this small gadget that was used to check for leaks and fill in the gaps in the plan. He cast a satisfied look at the second brother beside him who had always been obedient and peaceful, and patted his thin shoulder:

"Second brother, I have really given you a hard time over the years. I gave up my career on Hebei Road and returned to a small place like Longcheng to help my brother. I have stayed there for so many years. It is really a bit unfair."

Liu Zian raised his hand, covering the back of his eldest brother's hand, and shook his head seriously:

"It's all for the Liu family."

"That's right, it's all for the family left behind by our fathers."

Liu Ziwen's always serious and calm expression softened a little and he said softly:

"Brother Wei is very happy that you can always think like this. Brother Wei once said it, and I still remember that sentence now... As long as the eldest brother has it, he will never be without you.

"You haven't been married in these years, and when I asked you what kind of woman you wanted, you didn't tell me...

"When the big thing is done and you are promoted to the new rich in the two capitals, my eldest brother will find a good marriage for you. You can go to the prince and ask for a distinguished daughter of the Wei family for you."

Liu Zian immediately shook his head, "No, I won't bother you."

"My second brother doesn't like girls from the Wei family. He thinks she's not honorable enough. Then... it's not impossible for a girl with the fifth surname to be noble."

Speaking of this, Liu Ziwen saw his younger brother's sickly face that seemed to lack interest, and his eyes were a little curious:

"My second brother never said anything, which one do you like?"

Liu Zian looked at his elder brother, smiled, and said nothing.

Liu Zilin interrupted, "Brother, where am I?"

Liu Ziwen hated the iron and said: "You should correct the problem first."

Liu Zilin scratched his head and joked: "My younger brother's requirements are not high, my sister-in-law is just fine."

Liu Ziwen hummed softly, and Liu Zian glanced at his third brother.

Immediately, he seemed to notice that Liu Ziwen looked in a good mood, and Liu Zian suddenly asked:

"Brother, why do you want to let the Wei family take the sword that we worked so hard to take away directly? What if... I mean what if, the Wei family wants to hide the good bow and all the birds are gone?

"Actually, brother, you said... Let our own family become the sword master of that sword, and without delaying the continued alliance with the Wei family, maybe we can use the bargaining chip to jump to a more important position, and turn from a vassal to an ally. Wouldn't it be better for the family?

."

"Second brother!"

Liu Ziwen interrupted suddenly, his face was as dark as water, he stared seriously and said:

"Don't say these words again, don't even think about them in your head...not to mention, it is unrealistic for a man to have a jade.

"The Wei family has invested so many resources, waited for such a long time, and the boss Li sent us promised us everything... But all this is not without cost.

"If they didn't have absolute control over it, how could they trust us to leave it all to us?

"Second brother, the human heart is not like a snake swallowing an elephant, so we must observe it."

Liu Zian lowered his eyes and agreed: "Yes, brother, I'm just talking, giving you an immature suggestion."

"It won't happen again."

"yes."

Liu Zian raised his head and smiled.

Liu Ziwen took another look at him, tapped the armrest twice with his palm, and stood up suddenly:

"Walk."

"Where are you going, brother?"
