But Han Jingyun knew something was wrong with Lu, but he didn't know what was wrong. Fortunately, she had a good brother, so she could only look at Han Du pitifully, hoping to explain her confusion.
Han Du did not hide anything from his sister and said directly: "The Lu family is able to turn a blind eye even to the position of the stepmother and the crown princess. What kind of plot do you think she has?"
"Zhu Xiongying!" Han Jingyun suddenly realized and said immediately.
Han Du's expression did not change at all, and he said in a tone that was almost descriptive: "Not only Zhu Xiongying, I also suspect that Crown Princess Chang has become a coward at such a young age, and maybe she was the one who did it."
At this point, Han Du looked at the girl up and down, and said with a look of reminding her: "Lanyu once said that Chang had practiced martial arts with King Kaiping since he was a child, and his body and bones were very strong. Such a person would be so young. Are you going to leave now?"
Han Jingyun couldn't help but nod when he heard this, agreeing with his brother's view. It is true that frail and sick people die young, but it is really unjustifiable for a person who has practiced martial arts since childhood to die young.
"Then, if it's Lu, how do you think she did it?"
"The most likely possibility is poisoning. And it is a chronic poison that is difficult to detect." Han Du responded succinctly.
Han Jingyun had a puzzled look on his face and couldn't help but look up at his brother, "Poison? What kind of poison, even the imperial doctor can't tell?"
Han Du shook his head helplessly, "This is too much. I know more than one kind for my brother."
Originally, Han Jingyun thought that there was no such poison in the world, but he was shocked by his brother's words. There was more than one such poison?
Han Jingyun swallowed secretly and looked at Han Du with an inexplicable meaning in his eyes.
"What, you don't believe it?" Han Du thought that the girl didn't believe what he said, so he said casually: "If someone made a kettle with lead, used this kettle to boil water every day, and then gave the water to others to drink. It wouldn't be much more Years, this person will definitely die. And whether it is a kettle or the water he drinks every day, no matter how he checks, there is no trace of toxins."
Can people be poisoned by boiling water in a lead kettle? This method of poisoning is simply unbelievable, but in the eyes of the elder brother, it seems to be normal... Han Jingyun couldn't help but trembled, and looked at the elder brother with some fear, as if he was a big man Bad guys in general.
Han Du didn't notice the girl's expression, and continued to talk to himself: "But the poison in Chang's family is definitely not this kind of poison."
"Why?" Han Jingyun suddenly became curious when he saw his brother shaking his head in denial.
"Because, being poisoned by this kind of poison, the first and most likely cause is extermination. Even if you are pregnant with a child, it will lead to miscarriage. Since the Chang family gave birth to Zhu Xiongying and Zhu Yunxi safely, it means that it is definitely not the case. This kind of thing." Han Du is fully confident about this. The main manifestation of lead poisoning is that it affects fertility. Of course, lead poisoning can also be fatal, but only after long-term, large-scale accumulation.
Seeing Han Jingyun's solemn face, Han Du secretly took a breath and said, "It's good if you know how to be vigilant. If you know how to be vigilant, my words will not be in vain."
Han Du stretched out his palm and leaned on the teacup with the back of his hand. He warmed it up and it was just right to drink. He picked up the tea with the tea buds floating on it, took a sip, and said to his sister: "Brother, I originally planned to keep these words in my heart today and not say them to anyone. But since you insist on entering the palace, brother I have no choice but to tell you. I hope you can be more careful about Lu, especially when it comes to food and incense. "
Han Jingyun nodded, knowing already.
Then he asked his elder brother in confusion: "Eldest brother, why don't you tell the prince these words?"
Han Du shook his head slightly and sighed: "These are just Brother Wei's guesses. There is no evidence. How can I report it to the prince? Brother Wei hopes that you can just know it yourself. It's not good to tell him rashly."
Han Jingyun saw that although his brother said there was no evidence, from his bright eyes, Han Jingyun could tell that he was probably 70-80% sure about this matter.
After all, Lu's various actions were indeed too abnormal and suspicious. Perhaps in the eyes of ordinary people, when they don't know that there is such a thing as chronic poison, everything about Lu's family seems to be barely explainable. But in the eyes of those whose brother is familiar with this kind of thing, there are flaws everywhere.
"Brother, if you see Chang's symptoms, can you guess whether she is poisoned?" Han Jingyun asked thoughtfully.
"It should be okay." Han Du looked at the tea cup in his hand and replied calmly.
But then he shook his head and smiled, "But this is impossible, after all, Chang has been living in poverty for so many years."
Suddenly, Han Du suddenly realized and looked at Han Jingyun, warning her in a deep voice, "Don't think about messing around. As a brother, please don't interfere in this matter."
Seeing that the girl was puzzled and even had the urge to find out, Han Du sighed and said: "You must not get involved in this matter. If you interfere, no matter what the final result is, it will be harmful to you. It’s useless. The reason why I’m telling you this is not to let you get to the bottom of things, but to remind you to be wary of Lu. No matter what she explains to you, don’t get involved.”
"I listen to brother." Seeing Han Du's panic, Han Jingyun finally gave up his previous idea and nodded in agreement.
"Don't feel aggrieved. This is why Brother Wei doesn't want you to enter the palace." Han Du put his hands in a pool, shrugged and said helplessly: "Once you enter the palace gate, it is as deep as the sea. You have to use all your strength to protect yourself. How can you care about the life and death of others?"
The brother and sister had a conversation and finally solved the knot in each other's hearts.
Han Jingyun returned to the academy to teach as usual, while Han Du began to travel back and forth between the Municipal Department and the academy.
Hearing that Han Du finally no longer objected, Zhu Biao came to Han Du's home overjoyed and thanked him personally.
"Han Du, I won't say anything unnecessary. All in all, I still have to thank you for the matter between Gu and Han Jingyun."
Han Du curled his lips indifferently and said calmly: "It's the parents' orders and the matchmaker's words. When you and Jingyun were together, you really didn't have the right to talk to me, and your highness didn't need to say thank you."
"In any case, you are Jingyun's brother after all. I am very happy to get your consent." Zhu Biao said with a smile on his face, slightly embarrassed.
Han Du took a deep look at Zhu Biao and said to him: "Jingyun has indeed sacrificed a lot to marry you. I hope you can treat her well in the future."
"Don't worry, Gu will treat her well and give her the best in everything." Seeing that Han Du really had no grudge, Zhu Biao promised happily.
