Shu'er, the clever girl, thought of many ways to torture people. Gu Yunru shook her head and thought that this was not a good way, so she lured out a small poisonous insect from her ear and drilled it into the boatman's ear. As soon as the poisonous insect entered his body, it began to torment him. The boatman was in so much pain that he wanted to die. He was tortured so badly that he quickly begged for mercy from everyone: "Auntie, please forgive me, please forgive me, isn't it enough for me to say it?" The boatman had to give in.

"You are going to Yangzhou this time, and the order was sent from Yangzhou. We are just following the routine, so the person behind the scenes is in Yangzhou.

You will encounter more dangers and tribulations this time, so you better take care of yourself. But can you get that little thing out of here, aunt? I feel so bad right now."

The boatman was crying and laughing, and his spirit had been tortured to the point of madness. Gu Yunru smiled coldly and clapped his hands, and the little insect came out of his nose. Looking at the little poisonous insect, Gu Yunru smiled proudly and said, "This is called a naughty insect. It won't hurt people, but it is best at torturing people."

When Ji Heng saw the bug coming out of the boatman's nose, he vomited on the spot. Shu'er quickly helped him sit aside and poured him a cup of tea to comfort his bad mood.

Rong Zhen had already witnessed how powerful Gu Yunru was in using poisonous insects, and it was also thanks to Gu Yunru that the boatman was able to entertain them honestly.

The boatman lowered his head tiredly and said, "I have told you the secret. I am sure my master will not let me go back alive. Please give me a quick death." Rong Zhen knew that as a death warrior, his greatest duty was to obey his master's orders. Now that he had leaked the secret, he had no way out. Both the black and white worlds would no longer tolerate him, and they sent him to heaven with a palm.

Ji Heng was shocked when he saw this, and he rushed over, saying, "If you kill the boatman, who will drive the boat?" Gu Yunru's eyes sank. What Ji Heng said made sense. If the boatman died, who would drive the boat? But in a blink of an eye, Rong Zhen was looking at everyone with confidence.

So the task of driving the boat was handed over to Rong Zhen. There were still four days of journey to get there. Gu Yunru tossed and turned in bed and couldn't fall asleep.

Shu'er opened her eyes dazedly and asked, "Aunt, what's wrong with you?"

"It's nothing. It's so boring to stay on the boat for so many days. I wish God could give me a deck of playing cards." Gu Yunru muttered to herself. She had become accustomed to the slow pace of life in ancient times, but she had never lived such a boring life before.

She can't cook and can't treat others. In fact, there are so many merchants on the ship, but not a single one of them has any disease like malaria. She, a great doctor who can bring people back to life, has to live such an ordinary and boring life. When will it end? Shu'er frowned in frustration, "But I think the prince is quite fast in driving the ship. I didn't expect that the prince is really omnipotent."

"You'd better say this to his face. He'll be so happy that his tail will be lifted up. I don't know how Aojun and the others are doing now, and whether Huan'er and An'er miss me." As he spoke, the corners of his mouth couldn't help but rise.

Time passed quickly and they arrived in Yangzhou. Naturally, there were local officials and dignitaries waiting for them. When they arrived in Yangzhou, it was also the time when Rong Zhen and Ji Heng parted ways.

He had not explained the situation to anyone before arriving in Yangzhou. The imperial examination system for selecting officials was a continuation of the Han Dynasty's system of selecting officials by subject. The emperor knew that there were many loopholes in it. Gu Yunru had also received a batch of names before this. These names were recorded by the people of Zhuzhou who had submitted their contributions according to their aspirations and conduct.

Someone chose an empty room in a private school next door, paid some money and started moving in. Gu Yunru watched Rong Zhen settle down and couldn't wait to read some letters and aspirations handed in by officials from all sides, which wrote about the malpractices of this imperial examination.

Seeing her husband so serious and absorbed in his work, Gu Yunru made a few snacks for him and placed them aside while he watched.

Gu Yunru had long forgotten the history of the imperial examination system. It seemed that only outstanding scholars recommended by the powerful could enter the hall to take the exam. It was difficult for a poor family to produce a noble son. In order to change their fate, some people from the lower class studied until they were old.

I just hope that I can pass the imperial examination one day. I not only think of that guy Fan Jin, who died due to excessive excitement, but also remember that during the reign of Emperor Wen of Sui Dynasty, there were no subjects for Jinshi and Mingjing in the four and ten subjects. I don't know what this fictional dynasty should do.

"Hey..." Rong Zhen's brows were wrinkled into a ball. After looking at the letters, he crumpled them into a ball in dissatisfaction and threw them out. Seeing that he was so angry, Gu Yunru quickly took the remaining letters and looked through them.

"These officials' recommendations are all from wealthy families." Gu Yunru understood after seeing this. It clearly stated the family backgrounds of these people. What great achievements the scholars had made, these things were written down by flattery and receiving money. It seemed that these officials were not doing their work with all their heart.

“This is what is bothering me. When can I make these guys realize…” Rong Zhen’s face turned pale, showing how worried he was.

"Scholars who want to participate in the selection of officials must first be recommended by officials. This system is indeed a bit unfair. They should be given the right to submit their own petitions, but is there any way to completely eliminate this problem?" Gu Yunru took a general look and knew that those who were recommended by officials were not people with real talents. If they were allowed to become high-ranking officials, the entire Da Qi would be finished one day.

"These people are secretly giving and protecting each other. If we want to carry out a thorough reform, I'm afraid there will be another wave of dissatisfaction among the people. These guys are rigid in their thinking and are not very satisfied with the subject-based election system." Rong Zhen stroked his head worriedly. Gu Yunru hurriedly walked up to him, gently pinched his shoulders, and rubbed his head.

"Don't worry about it. Anyway, we are here to solve the problem. When the time comes, you can write a letter to the emperor and report the situation. I believe the situation will be reversed."

Gu Yunru touched his shoulder. The imperial examination of Da Qi was held every three years, but every year, tribute scholars were selected to the court. The number of candidates was very small, and the examination did not seem that important. However, the national examination, which was held every three years, was held in Yangzhou, and many officials would flock there.
