At this time, Zhang Zong was holding a bottle containing nitroglycerin in his hand, carefully took out the upper nitroglycerin solution, and poured it into another porcelain bottle. As for the lower pure nitroglycerin, it was left in the original bottle.

In fact, the nitroglycerin made by Zhang Zong is very limited, only a thin layer on the bottom of the bottle. However, for safety reasons, he immediately added water to the nitroglycerin. This thing is safer only if it is hidden in water.

As for the upper solution taken out, Zhang Zong was going to give Li Hong the medicine, and he would give it to him after he used it. Although it was a little troublesome to do so, it was better than Li Hong carrying a small bomb every day. If it exploded one day, Zhang Zong would probably have to be buried with him.

"Brother Shi, you really won't go?" Xue Shao asked Zhang Zong with a bitter face.

"I won't go. Have you remembered what I told you just now?" Zhang Zong handed the nitroglycerin solution to Xue Shao and asked.

"Remember, but you put in such a lot of effort to make the medicine, but you refused to hand it over to your cousin yourself. You didn't even want the credit. What are you trying to do?" Xue Shao asked in confusion in the end.

"What are you trying to do?" Zhang Zong thought seriously when he heard this question, and finally smiled suddenly, "Maybe he just wanted to do it, maybe he might be a good emperor in the future."

"This... what is this reason?" Xue Shao was amused and crying after hearing this. With his age and experience, he still couldn't understand the profound meaning of Zhang Zong's words.

"Don't worry about anything else. When you see the prince, just follow what I teach you. If he doesn't want to use this medicine, you don't have to force it. Everything depends on his own choice." Zhang Zong patted Xue Shao's shoulder and said.

"Okay, then I'm really going?" Xue Shao had no choice but to nod, just asking in a little tone.

"Go, tomorrow I will prepare a table of dishes you haven't eaten before. It's a thank you to you, but I have to buy the ingredients myself!" Zhang Zong finally solemnly stated that Xue Shao's ingredients were not important. It took several days for the meat I bought last time to finish it, and the eggs were not finished until now.

"No problem, wrap it on me!" When Xue Shao heard that there was something delicious, he immediately raised his chest and was confident. After saying that, he put the bottle containing nitroglycerin solution in his arms, then said goodbye to Zhang Zong, and then strode away from the flowerbed.

In the Qingliang Hall, Prince Li Hong was using lunch, a plate of vegetables, a plate of tofu, and a bowl of millet porridge. This was his lunch. Li Hong stretched out his chopsticks and picked up a piece of green vegetables and put them in his mouth. After chewing them for a few bites, he swallowed them hard. Then he drank the rice porridge and sent them down. Then he ate another piece of tofu. Although tofu was better than green vegetables, Li Hong also frowned because of the little salt and oil.

However, no matter how bad the vegetables and tofu were, Li Hong still forced himself to swallow it. Since he heard Zhang Zong's opinion last time, he has completely changed his diet. He no longer drank wine and meat. Other dishes should be light and even less oil. Although the imperial chef in the palace is skillful in cooking, he cannot make any delicious dishes under Li Hong's restrictions.

"Hu~" After swallowing the last bite of rice porridge, Li Hong finally breathed a sigh of relief. He had finished eating the tofu on the plate, but there were still a few slices of vegetables left and I couldn't eat it anymore. In fact, for him, it was still tolerated without meat, but he was really unbearable, but he ate less salt. He was a person with a strong taste and put less salt, and even the delicious dishes turned into tasteless in his mouth.

Just as Li Hong put down his chopsticks, Xue Shao walked in quickly. When he saw the lunch in front of him, he couldn't help but smile and said, "Cousin, you really have perseverance. I'm afraid that the monks in the entire capital don't have the precepts like you!"

"When did the monk follow the precepts? If you want to eat meat, you can come up with a reason for three clean meats, which is extremely hypocritical!" Li Hong also smiled at the moment. He has never liked Buddhism, not only because their Li family respects Taoism, but the most important thing is that Buddhism has developed too fast, and some places have already threatened the rule of the court.

"That's the same!" Xue Shao nodded thoughtfully when he heard this, and then smiled again, "Cousin, you have been vegetarian for so long, are you in better health?"

"It's not that fast, didn't Zhang Zong say that changing his diet just doesn't make the condition worse, and it can't really cure the disease. However, there are still some effects. For example, I feel that the pain every time I start to have a little less, and it's no longer like before. Every time I start to have an illness, it's like I'm going to die." Li Hong replied, which is also the main reason why he persisted.

"It's good if it works!" Xue Shao was relieved when he heard this, but then he turned his head and looked around, and then whispered to Li Hongdao, "Cousin, can you let everyone else in the hall go down? I have a few words to say to you!"

"So mysterious?" Li Hong felt a little funny, but he still waved his hand to let everyone in the hall retreat.

After Xue Shao watched everyone leave, he took out the porcelain bottle containing nitroglycerin solution from his arms, and then solemnly put it in front of Li Hong and said, "Cousin, this is a good medicine for treating your angina pectoris. Every time you start to get sick, you only need to apply it on your chest. Generally, it can ensure that you will not get sick for half a day!"

Li Hong stood up excitedly when he heard this, but then he showed a suspicious look and said, "Sanlang, aren't you kidding me?"

"My cousin, do you think I will joke about your condition?" Xue Shao asked with a grievance.

"Where did this medicine come from? Are you sure it can relieve my angina pectoris?" Li Hong believed that Xue Shao would not joke about his illness, but was worried that he would be deceived by others, so he asked again.

"The medicine was given to me by someone else. As for who this person is, don't ask me, I won't say it. And he will definitely relieve your angina pectoris, so he will try the medicine for it." Xue Shao replied with a bitter face. Some of these words were taught by Zhang Zong, and some of them were what he wanted to say.

"What someone else gave it?" Li Hong frowned when he heard this. After thinking for a moment, he immediately guessed the matter. He immediately smiled, "I understand. The person who gave you medicine is Zhang Zong, and only he knows so well about my condition!"

"I said I can't say it. Anyway, the person who sent the medicine asked me to tell you that this medicine can relieve your angina pectoris. If you believe it, use it. If you don't believe it, forget it." Xue Shao said with a tough bullet. Even if Li Hong guessed that the person who sent the medicine was Zhang Zong, he would not admit it. This was what Zhang Zong told him repeatedly before.

"Interesting!" Li Hong also sat down slowly at this time, staring at Xue Shao and said again, "If this medicine can really relieve my condition, it will definitely be a great achievement for him. Don't he want this achievement?"

Xue Shao looked up at the sky, as if he was not going to answer, but he muttered in a low voice: "I know what he is thinking?"

Xue Shao's words also confirmed Li Hong's conjecture, which made him even more curious. Last time, Zhang Zong had clearly told himself about his dietary control, but this time he gave the medicine, it was mysterious. It would be fine to use Xue Shao to pretend to be, but Xue Shao still refused to tell him that the person who gave the medicine was him. Why is this?

"Okay, I believe you, I'll keep this medicine!" Li Hong thought for a moment and finally reached out and picked up the porcelain bottle. Since he had believed Zhang Zong last time, there was no reason to doubt him again this time.

"It's great, but Zhang... cough~" Xue Shaoyi was excited and almost called Zhang Zong's name, which made him a little embarrassed for a while. Fortunately, Li Hong pretended not to hear it, so he continued, "The drug sender asked me to tell my cousin, if the medicine works, you must not let people know that it was given to you by us. Even if you say it, I won't admit it. No matter what the reason is, don't let people know that there is a mysterious drug sender behind this medicine."

"Okay, I promise you!" Li Hong was too lazy to ask the reason at this time, because he knew that Xue Shao would definitely not say it.

Seeing Li Hong agreeing, Xue Shao was also overjoyed and immediately pointed to the medicine bottle excitedly and introduced: "The usage of this medicine is a bit special, and there are many precautions. I'll teach you!"

Xue Shao explained the use of nitroglycerin solution to Li Hong. In addition to applying it to his chest, he also told him how to take it orally, but he told him that although this method works quickly, it may have adverse reactions. In addition, there are some precautions when using medicine, etc. Li Hong also wrote down one by one.

"This medicine can only relieve the symptoms of the disease, but it cannot really cure the disease. If you use it too many times, the efficacy of the medicine may be weakened. So cousin, you cannot rely too much on it. The way to truly relieve the disease is to control your diet and maintain your body." Xue Shao finally reminded him again as Zhang Zong said.

"I understand, it's a good time!" Li Hong nodded solemnly after hearing this, and then expressed his gratitude to Xue Shao.

"Haha, I'm just a messenger. Now that I've finished speaking, I won't bother my cousin anymore. Goodbye!" Xue Shao said at the end, he stood up and turned around and left. He was afraid that he would let go if he stayed here.

Looking at Xue Shao's back as he left, Li Hong smiled helplessly, then his eyes fell on the porcelain bottle in his hand again, and his face slowly showed a look of contemplation. Zhang Zong's performance was very strange, which aroused his great interest. The more he came into contact with Zhang Zong, the more he felt that Zhang Zong's body was shrouded in a cloud of fog, and he couldn't see clearly no matter how he looked.

In the evening, after dinner, Zhang Zong watered the flowers and plants in the flowerbed for a day. The weather is too hot now, and many flowers and plants are a little lacking in water. For this reason, he had to water them all sooner or later, otherwise the flowers and plants would not be able to survive this summer.
