However, after Lin Shen showed his "King of Chu" waist token representing his identity, the Qian Niu Wei didn't dare to stop him.
Even all the way, they escorted Lin Shen to the gate of the Eastern Palace, without even announcing their arrival.
There were only two people in the room: Li Shimin and Empress Changsun.
They clearly weren't prepared for Lin Shen's visit.
Li Shimin coughed lightly and asked softly, "Why did the King of Chu visit so late?"
Lin Shen, casual as ever, pulled out a chair and sat down, waving his hand. "Don't call me 'King of Chu,' it feels weird. You can call me Xiaolin or Lao Lin."
Li Shimin's expression was a bit odd.
Empress Changsun's expression was equally strange.
They had never seen someone like this.
Especially Li Shimin, he had never expected this.
When Lin Shen was in the teahouse, he talked about giving him credit without any deduction. Li Shimin thought Lin Shen was someone who valued fame and fortune, but judging by his current attitude, it seemed that Lin Shen didn't attach much importance to his identity as the King of Chu?
Lin Shen took out the pesticide bottle from his pocket and placed it on the table, grinning. "I mentioned the locust plague to you yesterday. Today, I searched through the ancestral treasury and found something good."
Li Shimin looked at the milky-white bottle on the table with some confusion. "What good thing is this?"
Lin Shen explained, "The scientific name of this thing, well, its official name is saline pesticide, but you can just call it insecticide."
"Its function is just like its name, effectively killing insects."
Li Shimin shuddered. "Including locusts?"
Lin Shen nodded. "Yes, including locusts."
Li Shimin couldn't sit still and stood up, circling around to the front of the table, his big face almost slamming onto the bottle, curious. "How do you use this thing?"
Lin Shen fell silent.
How to use it?
He hadn't drawn a pesticide sprayer.
He was so caught up in his excitement that he forgot about this.
Li Shimin looked at him curiously.
Lin Shen waved his hand. "Let me think about it. I haven't had much contact with this thing..."
Without a pesticide sprayer.
Use a watering can instead?
Anyway, it's just sprinkling it out. However, using a watering can wouldn't be as precise as a professional sprayer.
Lin Shen said softly, "Just use a watering can."
"However, when using it, remember to dilute it with water. For a regular watering can, just pour in about a bottle cap's worth of insecticide."
Li Shimin was taken aback. "Is it that simple?"
Lin Shen nodded. "Yes, it's that simple."
"However, there are a few things to pay attention to."
Li Shimin listened quietly.
Lin Shen continued, "This thing has a certain degree of toxicity."
Li Shimin's face changed drastically, immediately moving away from the pesticide.
As an emperor, he had always kept his distance from toxic things.
Lin Shen waved his hand, saying softly, "There's no need to be so alarmed. As long as you don't drink it or soak your body in it for a long time, you won't get poisoned."
Li Shimin breathed a sigh of relief.
"And the toxicity of this thing isn't very strong. Even if you accidentally ingest a little, it won't be fatal. Just wash your stomach first, that is, vomit out what's in your stomach."
"Then drink some mung bean soup, or honey water, both can alleviate the toxicity, just rest for a few days."
Listening to Lin Shen's explanation, Li Shimin's expression gradually softened, and he sat back in his seat. "This thing, is it like self-heating rice, where you can have as much as you need?"
Lin Shen shook his head.
A disappointed expression appeared on Li Shimin's face.
Then he heard Lin Shen say, "Of course, there will be as much as you need, but it can't be provided for free like self-heating rice."
Li Shimin raised an eyebrow. "What do you want?"
Lin Shen shrugged. "Of course, I want money. It's a locust plague now, and I don't plan to ask for too high a price. I intend to sell it for ten coins a bottle."
"Ten coins?"
Li Shimin was somewhat surprised.
This price was very cheap, almost all farmers could afford it.
However... the cost of this thing was probably more than ten coins.
Li Shen's expression showed a hint of embarrassment. "Don't look at me. I'm a businessman, not a saint. Providing self-heating rice for free was just to maintain the identity of the King of Chu. Otherwise, when I do business in the future, someone might take advantage of their power and try to eat up my shop."
Hearing this, Li Shimin couldn't help but cough a few times, feeling somewhat embarrassed.
He was also aware of the incident involving Hou Junji.
As soon as the conflict erupted between Hou Junji and Lin Shen at the gate of the Chang'an County Office, he received this report.
Lin Shen continued, "Selling for ten coins is just to ensure that farmers can afford it. If it's too expensive, they won't be able to buy it. If they can't solve the locust plague, this thing won't be of any use."
"Of course, if the Tang Dynasty wants to buy it, I'm open to that business too."
Li Shimin asked, "What if I want to exchange it for rewards?"
Lin Shen gave Li Shimin a strange look. "I'm the King of Chu now. What else can you offer me?"
Li Shimin's face stiffened.
Yes!
Now Lin Shen was already the King of Chu, the most respected person in the entire Tang Dynasty apart from the emperor himself.
What else could he offer to get insecticide for free?
Could he appoint Lin Shen as a vice-emperor?
That was impossible...
Li Shimin had to firmly grasp the imperial power in the hands of the Li family.
Li Shimin sighed, "Ten coins it is then, but after the locust plague is over, how much will you sell a bottle for?"
Lin Shen shook his head. "After the locust plague is over, I won't sell this thing anymore."
Li Shimin was somewhat surprised. "Why? This thing is so good..."
Lin Shen waved his hand. "You are the emperor, you are good at governing the country and waging wars, but you don't understand this thing. This kind of insecticide is indeed quite good, but it's only because of the current locust plague that it can be brought out for emergency use."
"Do you think it can only kill insects?"
"Let me tell you, this thing has tremendous killing power against insects. Butterflies, bees, and even some small animals, once they come into contact with this substance, are bound to die."
"Experts in destroying the ecological environment."
Li Shimin frowned, full of doubts. "Destroying the ecological environment, what does that mean?"
Lin Shen sighed, looking helpless. "Explaining this to you, you won't understand for a while. Just know that if this thing is used too much, apart from humans, I'm afraid you won't see any other living creatures in this land."
Li Shimin felt somewhat uncomfortable with Lin Shen's attitude.
There was a feeling of being treated like a fool.
An overwhelming sense of knowledge.
This was the first time Li Shimin had felt this way in front of someone since he became an adult.
The last time was when he was young, and the teacher his father hired for him made him feel this way.
But the last sentence was very easy to understand.
Apart from humans, if no other creatures can be seen, can humans still survive?
