Su Bei was of course not happy, "You caught a cold the last time you came back. What if you catch a severe cold again? Prince Zunyi is not here."

The little bun hung his head in a sullen mood. Little Tangyuan rushed over and hugged her legs. "Mom is the best. Mom loves us the most. There is really nothing interesting here. We want to go to the river to play. I promise to keep an eye on the little bun and never let him go into the water again!"

Without waiting for Su Bei to refuse, Chu Younan spoke up: "There has been no movement in the north these days, so Dad will go with you! But we have to make it clear that you have to listen to Mom when you go!"

Little Baozi and Little Tangyuan nodded repeatedly.

There were not many people by the river, and when they saw the emperor coming, they all hid far away. The two children were having a lot of fun, they just played by the river and didn't really go into the river.

Su Bei finally felt relieved and sat by the river with Chu Younan to enjoy the spring breeze.

Not far away, little Baozi and little Tangyuan were laughing and giggling, and no one knew what they were playing.

The two children grew up together. In fact, Xiao Tangyuan knew that Xiao Baozi liked to tinker with insects. But girls are always a little afraid of insects, so when Xiao Baozi gave his big red spider a bath by the river, Xiao Tangyuan still screamed.

However, she saw the little boy playing with insects every day, but she never saw him get bitten, so she was still a little curious. She called out and then squatted back down.

"This thing really doesn't bite?" Little Tangyuan looked at the red spider in his hand with fear and curiosity.

As the little bun poured water on the red spider, he said, "It will bite whoever I tell it to bite. If you don't believe me, take it and see. I promise it won't bite you!"

"Really?" Little Tangyuan hesitated and didn't reach out his hand.

The little bun said solemnly, "Really! If I bite you, I will let you bite me ten times!"

Although little Baozi loves to cheat his dad, he has never cheated little Tangyuan, so little Tangyuan timidly stretched out his little hand.

The huge red spider looked bigger than her palm. Little Baozi put it down easily, but little Tangyuan caught it with trepidation.

Although he had prepared himself mentally, when the spider touched his palm, Tangyuan couldn't help but let out a low cry and pulled his hand back.

"What's wrong? Did it bite you?" The little boy nervously pulled her hand over and examined it carefully.

Little Tangyuan shook his head, looking apologetic. "I didn't bite it, I was just a little scared. What should I do now? It fell into the river!"

"It's good that it didn't bite you!" said the little bun as he searched in the river. Then his eyes fell on one place with a look of joy, "Look! It can swim, and it swims so well!"

Following his gaze, little Tangyuan also saw the red spider swimming in the river, so he clapped his hands and said, "How fun! How fun!"

Su Bei and Chu Younan came over after hearing the noise. They looked at the river surface and Chu Younan asked, "What's so interesting?"

"It's a spider! Little Baozi's spider can swim, how fun!" Little Tangyuan said, pointing to the river.

When she heard about the spider, Su Bei subconsciously took a step back, but because the distance was far, she still watched with the children.

You know what, this red spider can swim really well. It swims up the river as if it were floating on water with the skill of light Kung Fu.

As they watched, Su Bei suddenly pointed at the river and asked, "What is that?"

Chu Younan was also watching with a frown on his face. After hearing what she said, he hurriedly used his lightness skills to swim upstream.

The scene in the river was a bit strange. If you didn't look carefully, you wouldn't notice that there were some needle-sized things in the river water. Because they were translucent green, the few people just now didn't notice them.

But now the red spiders were floating on the water, and those green dots seemed to be frightened. They were running upstream desperately, and when they gathered together they became conspicuous.

Chu Younan was very curious, so he took off one of his boots and filled it with green water before returning.

"Look, what's that in the river?" He poured some water from his boots onto the white towel, exposing the green dots in front of several people.

Su Bei shook his head. Little Tangyuan was puzzled. Little Baozi was the first to speak: "It's a poisonous insect!"

Chu Younan and Su Bei immediately became nervous, and Su Bei hurriedly asked, "Do you know him?"

"I don't know." The little bun shook his head, "But I can feel that this is a poisonous insect!"

He is a self-taught person, and it is amazing that he can reach this level. It cannot be forced, but one cannot disbelieve what he says. Su Bei looked at Chu Younan again.

Chu Younan knew what she meant without her having to speak. He quickly called someone over and ordered, "Pass the order! Have everyone check their water and food. If there is this green stuff in it, they must not eat or drink it!"

Even as they were talking, Starscream had swum out of sight.

Less than half an hour later, someone reported back that most people did not notice any green spots in the water or food, except in the two buckets of water that had just been pumped back from the kitchen, but they had not been used yet.

"Be extra careful during this period!" Chu Younan reminded again.

Of course people paid attention and filtered the water with cloth before using it. So after three days, none of the Ukrainian soldiers had any problems. On the contrary, some people who had always suffered from diarrhea were now cured.

But it’s different in the north.

When people first started to have diarrhea, no one noticed because there were only a few cases. But the next day, a large number of people started to have diarrhea, and this caught Bei Yanming's attention.

He ordered someone to fetch some water, and when he looked at the water he realized there was a poisonous insect in it. He immediately became furious and smashed the third table.

"Yao Shang! Are you a spy sent by the Wu Kingdom? You actually cast a curse upstream!"

Yao Shang was extremely shocked. "Your Majesty, that's not true! I am loyal to Your Majesty!"

As he spoke, he picked up the water with the Gu worm and examined it carefully, only to find that his Gu worm was indeed in the water.

"Your Majesty, please allow me to go to the river and find out what's going on!" Yao Shang requested.

Bei Yanming immediately ordered his men to take him to the river. This trip was of great significance, as Yao Shang discovered a big secret!

The place where they usually fetched water was full of those green poisonous insects. Going upstream, there were hundreds of meters of such insects.

“We can only ask people to go upstream to fetch water…” Yao Shang was sweating coldly.

"Where are the soldiers who were infected with the poisonous insects?!" Bei Yanming said angrily.

"I will speed up the research on the antidote!" Yao Shang broke out in a cold sweat. He originally wanted to use these poisonous insects on the Wu people, so he never thought about the antidote. He wanted to use the most poisonous one.

Even if he didn't support it in the future, by the time he developed it, the North would have lost another 100,000 soldiers...
