"You're washing your face with soap?" Henry Clark looked at Little Daisy, whose face was covered in foam, and asked.

Little Daisy nodded obediently. Heaven knows how much soap this little girl used at once—otherwise, there wouldn't be so much foam.

"Perfect, hurry up and finish washing your face. Don't pour out the wash water, bring it over to me—I need it!" Little Daisy's greatest strength was her obedience, and even if she didn't understand, she wouldn't ask unnecessary questions. Hearing Henry Clark's words, she immediately turned and ran back to her room. In no time, she brought over the wash water. Seeing the water had turned milky, Henry Clark was sure that the soap he gave this little girl wouldn't last more than a few uses.

The most effective way to deal with food poisoning is, of course, gastric lavage. This method works for both humans and dogs. Old Martha fed the dog arsenic, but he didn't know how to use it properly and actually mixed the arsenic with egg whites, which would undoubtedly weaken the toxicity of the arsenic. It's likely that after the tiger cub ate the arsenic, it took quite a long time before it died. But fortunately, because of this, the little black dog managed to hold on until now.

Giving a dog a gastric lavage isn't as particular as doing it for a human. In his previous life, Henry Clark had seen a vet perform gastric lavage on a dog that had accidentally ingested pesticides, and they used soapy water. The ingredients in soap and bar soap are almost the same, so Little Daisy's wash water would work just fine. Now, Henry Clark's headache was how to get the soapy water into the little black dog.

In modern times, a gastric tube is always used for lavage, but where could Henry Clark find a gastric tube now? Besides, a gastric tube can't be too hard—it needs to be somewhat flexible, but not too soft, or it won't go into the stomach at all. This really stumped Henry Clark. The little black dog was already half-comatose; if he didn't perform the lavage soon, it definitely wouldn't survive.

"Little Daisy, you hold the puppy first. I'll go find some tools to give it a gastric lavage!" Henry Clark handed the little black dog to Little Daisy, then quickly walked into the bedroom and grabbed the backpack he had brought from before. Inside were some syringes he had brought for Mr. Bennett, the gatekeeper, along with ten disposable syringes. These could be used for the lavage, but the key thing missing was a gastric tube.

Henry Clark rummaged through the bag but still couldn't find anything suitable for a gastric tube. Finally, he took out the bundle containing his clothes and searched through it a few times, but still came up empty-handed. Just as he was dejectedly about to stuff the clothes back in, suddenly, with a "clink," a bunch of keys fell out of a pocket.

Seeing the keys, Henry Clark's eyes lit up, because he noticed a fish-shaped keychain on them, and it was handmade from the kind of plastic tubing used for IV drips. Looking at the keychain, Henry Clark couldn't help but feel sentimental, because it was a gift from one of his students. That student had been sick for half a month, and Henry Clark had gone to his house every day to give him IVs. In the end, the student made this keychain out of IV tubing as a thank-you gift. It wasn't worth much, but it was a token of the student's gratitude.

Although the keychain meant a lot to Henry Clark, saving a life was more important right now, so he didn't hesitate. He took off the keychain, took it apart, and finally got a piece of IV tubing about a meter long. It was just the right balance of firmness and flexibility—perfect for use as a gastric tube.

With the IV tube and syringe in hand, he returned to the main room. Little Daisy was still holding the puppy, looking heartbroken. Henry Clark had her hold the puppy upright, pried open its mouth, and slowly inserted the IV tube into its esophagus. At this point, he had to be very careful not to insert it into the trachea—otherwise, it wouldn't be a gastric lavage, but a pulmonary lavage. If Little Daisy's wash water got into the lungs, not even a tiger could survive.

The little black dog was tiny, only about the size of two palms, so the IV tube didn't need to go in very far to reach the stomach. Without wasting any time, Henry Clark used the syringe to extract the contents of the stomach, then filled the syringe with soapy water and injected it into the puppy's stomach. Soon, the puppy's belly swelled up. He then used the syringe to extract the liquid again. After repeating this process several times, the soapy water that came out no longer had any strange odor, and only then did Henry Clark feel relieved.

"Alright, Little Daisy, go find some egg whites or milk, goat's milk, or something like that. We'll feed the puppy a little in a bit!" Henry Clark gently pulled out the gastric tube and gave instructions to Little Daisy.

Little Daisy agreed and dashed off. Henry Clark carried the little black dog into the bedroom, found a wooden box, and made a little nest for it. The puppy was still unconscious; if it didn't wake up, all of Henry Clark's efforts would have been in vain.

In the Five Elements, dogs belong to the earth element and are very resilient. Less than an hour after Henry Clark performed the gastric lavage, the little black dog actually woke up with a whimper, then vomited some more stomach fluid. Although it was still very weak, it knew to look for food, which made both Henry Clark and Little Daisy very excited. When Little Daisy put the goat's milk she found in front of the puppy, it actually stuck out its little pink tongue and started licking.

Seeing the puppy willing to eat, Little Daisy was so happy she almost jumped up. Little girls usually love small animals, especially this chubby, fluffy little black dog. In modern terms, it was simply "adorable." Such a creature was practically irresistible to little girls, so Little Daisy's reaction was no surprise.
