Bi Bi has been unwell for quite some time now. Despite taking medication, the illness hasn't subsided. Anything Bi Bi eats seems to induce nausea. Even when Grandma prepared some porridge and offered it to Bi Bi, just a spoonful made Bi Bi feel queasy. Sipping a glass of milk had a similar effect. The only thing Bi Bi can tolerate and manage to eat a few spoonfuls of is rice. In the past, my mom used to feed Bi Bi porridge and milk continuously without offering any rice, and as a result, Bi Bi got tired of them. Now, whenever porridge or milk is mentioned, it triggers nausea for Bi Bi.

After several consecutive days, Bi Bi has become quite thin. The enemy germs have hidden inside the cells and took the opportunity to attack.

Attack! At this moment, the Medicine Squad has infiltrated along with Bi Bi's Immunity allies, battling against the germs. The Immunity allies outwitted the germs when they were off guard and launched an attack. However, the Immunity forces are few in number and somewhat weak, and they were overpowered and defeated by the germs.

Grandpa remarked:

Bi Bi isn't eating anything, which is why the Immunity allies have weakened. My dear, please make an effort to consume some porridge. At the mere mention of porridge, Bi Bi almost felt nauseous. But remembering Grandpa's advice, Bi Bi managed to control it and replied: Yes, I will have some porridge! Grandma prepared a light, sugary porridge for Bi Bi to eat. This porridge was thinner than what Bi Bi used to eat before, making it easier for Bi Bi to swallow. And so, Bi Bi took a spoonful, then another, and another...

The following day, Bi Bi asked Grandma to cook rice for him to eat, as Bi Bi still preferred it. With determination restored, Bi Bi no longer felt nauseous. Thanks to that, Bi Bi managed to finish almost half a bowl of rice with braised pork and cabbage soup. By lunchtime, Bi Bi could also drink a glass of milk.

With rice and nourishing food in Bi Bi's system, the Immunity allies grew stronger. They launched another attack on the germs. One, two... The allies charged forward, creating a commotion among the germs. Caught off guard, the germs panicked and scattered. However, the Immunity forces were also exhausted and couldn't pursue the germs further. Both sides retreated.

But thanks to the balanced situation, Bi Bi no longer felt nauseous. Bi Bi ate rice with meat and vegetables, took medication, consumed a few tangerine segments, and drank a glass of water.

The Immunity allies grew much stronger and organized one final attack. The biggest Immunity ally shouted:

Advance and crush them! The entire group charged forward, stomping directly on the germs. Many of them were pushed into the body's waste channels, submerged in urine, and vomited out. A few were struck too hard and ended up in the intestines, sharing the fate of feces and expelled from the body without making a sound amidst the foul odor.

Finally, Bi Bi defeated the germs, regained strength, and returned to kindergarten.
