The story of Metchnikov, the best student of Pasteur, the father of lactobacillus, "I have discovered the secret to prevent old age: lactobacillus. I must now send it alive in the human intestine to succeed".

 My master, who not only bestowed me the gift of knowledge, but also treated me as his son, passed away into old age. Since his departure a question has plagued me: why must the curse of aging and death pass through humans? 

Therefore, I have since embarked on a long quest: to find a way to prevent old age. Finally, I discovered what would become the focus of my experiments: "Super Lactobacillus," which inhibits the production of toxins in the human body and heals the disease. Now, I had to succeed in sending the lactobacilli to survive the intestines.
