"Huh? It's you? Hahaha, I remember you, it's you, I've been looking for you for a long time, but I didn't expect you to come to the door by yourself, hurry up, let me draw a tube of blood again. After the old man saw Chen Fan's appearance clearly, he seemed to forget about the door of his house for a moment, and hurriedly walked towards Chen Fan.

"Blood draws? Oh...... I remember, it was you. But how did you become like this? Chen Fan looked at Professor Wang, who was a little familiar and unfamiliar in front of him, and asked.

Professor Wang, formerly known as Wang Dongsheng, that is, after Chen Fan and Yao Yong were attacked by a bumblebee last time, they met the medical rescue personnel, originally, it was impossible for a professor-level doctor to go out to participate in first aid, and it happened that Professor Wang had something to go to District D of Y City that day, so he followed the ambulance to the place of the incident, and after arriving at the scene, he found that the incident happened suddenly, so he joined the ambulance work smoothly, and at the same time, because of this, he curiously took a tube of Chen Fan's blood at that time.

It is this tube of blood that has made the professor in this biological research field addicted for more than half a month, and what happened in the outside world in the past half a month is not well known.

"I said Lao Wang, how did you become like this, you are dressed like this, how long have you not been out?" Chen Fan said incredulously.

The last time I met Wang Dongsheng, he still looked energetic in his fifties, but now that I see him again, this Wang Dongsheng has a scruffy beard, his eyes are bloodshot, the white coat on his body has turned gray, and his hair is almost stuck together.

"Out of the house? About seventeen or eighteen days. Don't talk about this yet, come on, come on, go next door, and let me draw the blood again. Wang Dongsheng's bloodshot eyes shone with excitement, and he grabbed Chen Fan's hand and was about to walk out.

"Eh, wait a minute, Professor Wang, I'm here to ask you for help this time, I have an emergency, an urgent matter to save my life." Chen Fan dragged Wang Dongsheng with his backhand and said anxiously.

"Looking for me? What's the matter? Wang Dongsheng turned around and asked.

"My father is seriously injured and in critical condition, and I would like you to help with an operation." Chen Fan explained.

"Surgery? It's been a long time since I didn't go under the knife. Isn't there a lot of excellent surgeons in a hospital? What kind of serious injuries do I need to have surgery? Wang Dongsheng asked strangely.

"Hospital? Oh, I almost forgot, your old man hasn't been out for nearly half a month, don't you know, the outside world has changed now? Where there are hospitals, doctors, it's the end of the world outside. Chen Fan said.

"What? Doomsday? Hahaha, I said little brother, have you watched too many movies? Wang Dongsheng laughed.

"You don't believe it? Come, come and see. Seeing that Wang Dongsheng didn't believe his words, Chen Fan hurriedly pulled him to the balcony and looked out.

"I'll go, what's going on, when did the greening of our community reach this point?" Looking at the greenery in front of him, Wang Dongsheng said with some surprise.

"What greenery, do you know how long it took for these plants to grow like this? Three days......" Chen Fan stretched out three fingers and shook them in front of Wang Dongsheng's eyes, and then pulled out a handful of half-meter-high weeds from the crack in the wall on the side and continued to Wang Dongsheng.

"This one grew out of the crack in the wall, and it only took three days to grow to this half-meter length, do you believe it? Not only that, but now all the animals and plants outside have mutated, the animals have become ferocious and bloodthirsty, the plants have become tall and stout, and countless people have died outside, my father was bitten by a bloodthirsty dog, and the wound was very serious, and he needed immediate surgery. ”

"You said it only took three days for this horse tang grass to grow so big? Deceptive, right? It would take at least three months for this thing to grow this tall. Wang Dongsheng took the weeds in Chen Fan's hand and said with a look of disbelieving.

"Don't believe it, do you still have food at home?" Chen Fan asked a question that made Wang Dongsheng inexplicable.

"Eat? There were only instant noodles and some ham sausages. Wang Dongsheng said.

"Where?"

"Here, what? Are you hungry? Hearing Chen Fan's words, Wang Dongsheng took the horse tang grass and took Chen Fan out of the gate and came to another room next door.

"You live alone, and you get two houses, local tyrant." Chen Fan said with emotion as he walked.

"I'm my laboratory in this room, huh, you want instant noodles and ham sausages, huh? Why is this ham sausage moldy? I remember eating it last time and it was good. Wang Dongsheng looked at the ham sausages that were already full of green hairs in the cupboard and asked strangely.

"Look, that's what I'm going to say, now all the food out there is moldy and hairy, by the way, when was the last time you ate?" Chen Fan turned his head to look at Wang Dongsheng and asked.

"It looks like yesterday at noon." Wang Dongsheng recalled.

"You eat one meal a day with your old man? Can the body stand it? Chen Fan rolled his eyes.

"Sometimes when you get busy, you forget about it. Well? Haha is okay, instant noodles can still be eaten, and the shelf life of this dehydrated food is long. By the way, you said the food outside is starting to get moldy? Wang Dongsheng turned his head and asked.

"Yes, not only have the animals and plants mutated, but the food has also deteriorated and molded very quickly, and a lot of food is inedible. Emma, why am I still discussing this with you, you should hurry up and save people with me. Chen Fan suddenly remembered the main purpose of his coming, and hurriedly pulled Wang Dongsheng to leave.

"Eh, wait a minute, I haven't got the test data yet, and besides, if you want me to go for surgery, at least you have to get a set of surgical tools, right? I don't have anything. Wang Dongsheng spread his hands and said helplessly.

Speaking of surgical tools, Chen Fan remembered the situation in the First Hospital he had seen before, and he was worried again, and couldn't help asking: "Speaking of this, Lao Wang, do you know where else you can get surgical tools and blood bags besides the hospital?" ”

"What? The First Hospital is right next to it, do you want to go far away? Wang Dongsheng asked a little strangely.

"You don't know, a hospital has been occupied by a powerful monster, and all those who enter the hospital have turned into dried corpses, and it's too dangerous to get in." Chen Fan explained.

"You're stupid, the first hospital can't work, then go to another hospital, there is more than this hospital in Y City, and if you can't go to a pharmaceutical company, there are several large pharmacies that also sell surgical equipment, there won't be monsters everywhere, right?" Wang Dongsheng said.

“…… I'll go, you're right, I'm drilling, near my home is the old hospital of the Second Hospital, you can go there to get tools, let's go, have you packed up, let's hurry up, my father can't last long. Wang Dongsheng woke up the person in his dream with a word, and Chen Fan, who had figured it out, said happily.

The return journey was quite smooth, because Wang Dongsheng was just an ordinary person's body, and he was too old to walk long distances, so Chen Fan found a motorcycle and drove Wang Dongsheng all the way to his home cautiously.
