This speed was undeniably fast, but Yun Qingshu also knew at this moment that the real crisis for the Chu Kingdom was about to arrive!

With the fall of Wei, Qin's eastward expansion was no longer hindered.

The entire northwest will be connected, and even if the three kingdoms unite, they probably won't be a match for Qin.

At this juncture, all we can do is defend the city and wait for things to change!

In the State of Chu, in an inconspicuous alley.

The little deer was talking quietly to a man.

"Master wants to kill the King of Chu?"

The man was on the fourth day of the lunar month; he was a spy planted by Lu Li within the Mo family.

Little Deer nodded and took out a bottle of poison from her sleeve, handing it to Chu Si.

"This poison is colorless and odorless. Find a way to get the King of Chu to ingest it, and he will die from the poison in no time!"

Chu Si frowned deeply. This task was far too difficult. Although he was by Yun Qingshu's side, it would not be easy for him to find an opportunity to poison the King of Chu.

"After this is done, come back here immediately, and I will take you back to Qin!"

On the fourth day, he looked at the little deer, nodded heavily, and then disappeared into the crowd.

On the fourth day after returning to the Prime Minister's residence, he didn't sleep well all night, thinking about how to poison the King of Chu.

The next morning, King Chu summoned Yun Qingshu to the palace with a map of the defensive fortifications, giving Chu Si an opportunity.

"Mr., let me help you move it."

These defensive fortification diagrams were accompanied by a large stack of bamboo slips. Yun Qingshu did not suspect anything, said "good," and then turned and got into the carriage.

On the fourth day, seizing the opportunity, he poured all the poison onto the bamboo slips.

After entering the palace, Chu Si carefully placed the scroll in front of the King of Chu.

Then, the King of Chu began to examine the contents. His hands were already stained with poison, but it would be of no use if he did not take it.

While they were trying to come up with a solution on the fourth day, it was noon, and the King of Chu asked Yun Qingshu to stay and have lunch with them.

During the banquet, the King of Chu and Yun Qingshu exchanged toasts and chatted happily.

Then the King of Chu reached out and tore off a chicken leg, and began to eat it with great relish. Seeing this, Chu Si finally breathed a sigh of relief.

After lunch, when the King of Chu wanted to discuss things with Yun Qingshu again, he felt dizzy and almost stumbled to the ground.

"Your Majesty? What's wrong?" Yun Qingshu asked hurriedly.

The King of Chu waved his hand and laughed, "Perhaps...perhaps I didn't rest well last night, so I won't keep you here today, sir."

Yun Qingshu nodded, not noticing anything amiss, and then left the palace.

Before Yun Qingshu could even leave the palace, news arrived that the King of Chu was dying!

Startled, Yun Qingshu rushed back, but it was too late. The King of Chu died with his lips turning purple and blood flowing from his seven orifices!

Crown Prince Xiong Chu, his eyes bloodshot, glared at Yun Qingshu and roared, "Men, seize this traitor!"

Yun Qingshu was taken aback, completely unaware of what was happening, and quickly asked, "Your Highness! Why is this?"

To everyone's surprise, Xiong Chu didn't explain anything to him at all, and directly put Yun Qingshu into the prison to await his punishment.

The news of the King of Chu's death spread throughout the entire Chu state in no time, and a month later, other states also received the news.

King Chu died, and Crown Prince Xiong Chu succeeded him as the new king!

Upon learning the news, Xiang Yan rushed back to the State of Chu day and night.

Xiong Chu still trusted Xiang Yan completely, after all, Xiang Yan was the person he admired most since childhood.

"General Xiang... my father!!!"

Xiang Yan's white hair made her look even more weathered. She knelt on the ground and wept bitterly.

After weeping with Xiong Chu for a while, Xiang Yan wiped away his tears and said, "Your Majesty, this matter was definitely not done by Yun Qingshu!"

To everyone's surprise, Xiong Chu said decisively, "General, I have already found out. My father died of poisoning. I have sent people to investigate everything my father came into contact with!"

"Only the letter sent by Yun Qingshu contained deadly poison!"

Upon hearing Xiong Chu's words, Xiang Yan was immediately stunned. He looked at Xiong Chu in disbelief, unable to believe that Yun Qingshu would do such a thing.

"I was already being very rational by not killing him!"

If Yun Qingshu hadn't been the leader of the Mohist school, Xiong Chu would have torn him to pieces long ago.

Xiang Yan simply couldn't believe that Yun Qingshu would poison the King of Chu.

He is now the prime minister of the State of Chu, the chief strategist of the Mohist school, and a pioneer who has been advocating resistance against the State of Qin.

Xiang Yan simply couldn't think of a reason for him to poison the King of Chu!

"Your Majesty, there must be something fishy about this. Could you please let me see Yun Qingshu first?"

After hesitating for a moment, Xiong Chu said, "I can, but General, please don't try to persuade me to release him."

Xiang Yan sighed and then hurriedly went to the prison.

Yun Qingshu racked his brains but couldn't figure out why the King of Chu would suddenly die from poisoning.

He started to recall every detail, but there was nothing wrong with it!

Suddenly, an image flashed through his mind.

That's a diagram of the defensive fortifications!

When he dined with the King of Chu, he also ate the food, so why was he unharmed while the King of Chu died?

That leaves only the defensive fortification map. It was Chu Si who helped him move it, and he hasn't seen it since.

"The fourth day of the lunar month...the fourth day of the lunar month!"

Yun Qingshu instantly realized that Chu Si must be an undercover agent that Lu Li had placed by his side!

To my utter surprise, he valued Chu Si's abilities and made him the head of the Mo family's intelligence network, constantly gathering intelligence for the Mo family.

But he's actually one of Lu Li's men?

"Lu Li, oh Lu Li, you've been hiding your true colors so well!"

Yun Qingshu was already feeling desperate. He had suffered repeated setbacks since he left the mountain.

As the saying goes, a good bird chooses a good tree to perch on. It was not easy for him to meet King Chu, who recognized his talent, but in the end, he ended up like this.

Lu Li! It's all because of Lu Li!

At this moment, Yun Qingshu was close to going mad.

When Xiang Yan arrived at the prison, he was shocked to see Yun Qingshu's appearance.

"Sir! What exactly happened?"

Yun Qingshu gave a bitter smile and slowly said, "I was betrayed by my own subordinates, no, I should say I was tricked by Lu Li."

Xiang Yan, puzzled, continued to ask, "What do you mean by that?"

Yun Qingshu then told Xiang Yan all his guesses, leaving Xiang Yan dumbfounded.

If he hadn't trusted Yun Qingshu's character, he would have almost thought it was a fabricated story.

What kind of person could orchestrate such a long plan and plant spies to remain hidden for so long?

"General Xiang, although I am innocent, Chu Si is still a member of my Mo family..."

Although Xiang Yan believed Yun Qingshu, it didn't mean that others believed him too.

Xiong Chu is like that. You think it has nothing to do with you? All he knows is that the poison was administered by the Mohists and that his father is dead.

"What... should we do?"

For a moment, Xiang Yan was also in a dilemma. He knew perfectly well that Yun Qingshu was not the one who did it, but he had no way to exonerate him.

Assassinating the king is a capital offense!

"In the end... he still lost to Lu Li!"
