On the night after Ba Niu left, the Jibei Royal Mansion welcomed an extremely mysterious guest.

"What's your name, where are you from, what are you doing here, don't be in a hurry, take your time." In a secret room, the king of Jibei personally interrogated the man who had come to surrender. He doesn't look like a good guy, with a sharp beak and monkey cheeks, and thief eyebrows. However, Chu Tianyao didn't believe what he said.

"The villain He Shouwu, who was originally from Dongduo, was deceived here because he mistook his friend, and now he knows the sinister face of that person, and he is here to make his head, hoping that the prince will forgive the villain's careless sin in making friends"!

He Shouwu was prostrate on the ground, and his voice was a little trembling.

"Who is the man who deceived you, and what is he planning?"

"My lord, I have already told the reporter", He Shouwu raised his head, and his two eyes were rolling: "Someone wants to use a trigger to detonate the virus, didn't he tell you?"

When Chu Tianyao heard him say it himself, his face changed. You must know that the matter of triggers and pathogens is a state secret, and very few people know about it. Especially the pathogen, after it was taken away, no one knew its whereabouts, not even the people of the League of Assassins could find it, and now he mentioned not only the pathogen, but also the trigger, and said that someone was going to detonate it in Dadu, which is really a bit appalling.

"And when and where is he going to detonate it?" Chu Tianyao didn't think so on the surface, but he was already anxious in his heart, he knew that this person might not be so reliable, but the news he brought was by no means groundless.

"Rest assured, they can't be detonated without me, because only I know how to use the trigger."

Looking at his confident appearance, his hanging heart was half relieved, he knew the precision of the trigger, and people without professional technology could not use it at all.

"Then who is your chief, and where is he now"?

He Shouwu frowned, looking thoughtful: "Where he is, I don't know very well, his name, I think adults have also heard of it, he is Li Youlan, a native of Dongduo."

"You, you said Li Youlan"? Hearing this name, he suddenly stood up from his seat, and after feeling his gaffe, he sat down again: "Is it Li Youlan, who is famous all over the world and is known as the first talent?"

"Yes, that's him". He Shou Wu gave him a very clear answer.

"So, didn't you book the time and location of your joint in advance?"

"Because we are a smuggler, he needs to get a pass, and he can't calculate the time of their arrival at all, so there is no way to book a time, but we agreed on a code."

"What code"?

"In the last room on the left side of the third floor of the Dengying Building, it is our exclusive room, and all the information will be written on the wall."

Chu Tianyao looked at Chu Xiong, the staff member beside him, and he knew how to go down. Turning around, he continued to interrogate He Shouwu: "So, have you already been there"?

"Been there".

"What was left on the wall"?

"The villain left the time of his arrival, and Li Youlan left a poem."

"What poem"?

"The villain ......, the villain is illiterate, so he doesn't know what is written". He sneered for a long time before he said with a red face.

Chu Tianyao couldn't help laughing: "That Li Youlan is really a nerd, it's ridiculous that such an important thing should have such a low-level mistake!"

He laughed for a while, and when he saw that he couldn't ask for any more valuable news, he asked a few people to take He Shou Wu to house arrest, and reward him after everything was verified.

The people who went to Dengyinglou to verify confirmed He Shouwu's words, and on the wall of the room where he spoke, they found that date and that poem.

Xijiang month

planting tree nests in the clouds,

Divide the beans and pick the melons.

The cup has come to the world again,

At this time, youth is priceless.

The rain comes and the tide is full,

Check plum blossoms when it snows.

A pair of paramecium on flat sand,

There are no springs, autumns, winters and summers.

Although Chu Tianyao had read the subset of scriptures and histories, after all, he was a martial artist, and he didn't know much about these poems and songs, he took the paper he traced down one by one, and read it more than a dozen times from beginning to end, but he still didn't see any problems. I had to hide it in my sleeve for the time being, and after I entered the palace, I showed it to Chu Yuxing. - He is a big fan of Li Youlan.

"This is a very simple riddle", Chu Yuxing only read it once, and pointed it out to Chu Tianyao: "The whole poem is written in Xingshu, and only the two words of youth are in regular script."

Chu Tianyao saw that it was indeed the case, but he still didn't understand how these two words conveyed information.

"Green for December, spring, dismantled is two days, the ancients to the sky, the earth, the road, the people's congress for the four, two, refers to the heaven and the earth. The sky is dry, the earth is kun, dry, kan, gen, zhen, xun, li, kun, dui, the qian hexagram belongs to one, the earth hexagram belongs to seven, the sum is one seven, and the seven and the twelfth are connected together, which is the seventeenth of December. -- The time they agreed upon should be the 17th of the following month."

Chu Tianyao was confused when he heard it, but he still figured out the last date.

"Then, as long as you wait in the room on December 17, Li Youlan will appear"?

"It should be so, but there is one thing that I don't quite understand, - since the person who came out is illiterate, why did Li Youlan use such a complicated code to contact him? Didn't he know that he was illiterate? How is this possible"?

How did he know that this poem was not for He Shouwu at all, or even for Chu Tianyao.

Chu Yuxing and Chu Tianyao made a very careful plan, wanting to catch turtles in an urn, they wanted to see this famous and courageous person with their own eyes. Let's see what kind of character he is, able to plan such a big and earth-shattering conspiracy.

On the evening of December 17, Li Youlan really appeared. He was dressed in dark clothes, and his hat was pulled very low, and he handed a wooden sign to the cabinet, and the man looked at him, and immediately gave it back to him, and let him go upstairs.

On the third floor of this Dengying Tower, few people usually come up, Li Youlan came to this booked room, opened the door carefully, and saw a richly dressed man about forty years old, standing with his back to the door.

He was not at a loss because that person was not He Shouwu, but came to the house extremely calmly, sat down opposite the person, and at the same time, took off the hat on his head, and a pale face appeared in front of the person.

"The number one talent in the world is worthy of his name", the man exclaimed, and sat down, and then someone came over to pour tea. He took a shallow dip, and his eyes kept staring at this face, as if he was afraid that he would disappear in the blink of an eye: "Courage is also the best in the world."

Li Youlan laughed loudly, but his weak body seemed to be unable to withstand this violent exercise, and he responded with a spasm.

"The most ruthless emperor in the Kyushu continent, and his courage is also the first in the world"!

"Seeing a character like you, it does take some guts", Chu Yuxing still drank tea leisurely, and said half-sarcastically: "But, it doesn't take too much."

Li Youlan laughed again, followed by a violent cough: "So, Your Majesty, do you know the power of pathogens?"

"Know". He's still so laid-back.

"So", he stared at him with an extremely sarcastic look: "Did you know that pathogens have an incubation period"?

"Incubation period"? There was a hint of surprise on his face.

"Its incubation period is a month," he laughed again.

It's a conspiracy! Chu Yuxing immediately bounced off his seat and looked at him with horror on his face.

"You guessed it right", now, it was Li Youlan's turn to look at him with sarcastic eyes: "That night a month ago, that is, before He Shou Wu came out, we detonated the pathogen."

"So what you did after that was to lure me here and infect me with the virus"? After a moment of distraction, Chu Yuxing sat down again. He was not without fear, and the anger of being fooled, and the contempt that came out of it, made him face his enemies with this condescending attitude.

Li Youlan shook his head: "I want to find a confidant to accompany me on Huangquan Road." You should know that we have been friends for a long time, and we are just one side away."

Chu Yuxing saw that he said solemnly, and knew that he was not joking, but he also understood that it was not the main reason.

"So, what about the King of Jibei"? He thought of Chu Tianyao, who had been unwell these days, and couldn't help but ask.

"He must die"! Li Youlan's tone was firm, and his fists were clenched together: "He is the person I must take away."
