Cao Hong bowed his hand and said: "yes, according to the results of the investigation of all the people in Cao's compound by my grandson, the only difference between those who are not infected by the epidemic of abdominal pain and those who are infected is in cultivation! All other aspects are almost the same, including food and daily life needs, which are under the unified control of the government's purchasing department. There is really no other suspicious place to be found! "

Looking at Cao Hong and the stern looking Cao, Bai couldn't help raising his hand, stroking his goat like moustache and shaking his head: "so, can we conclude that everyone in Cao's courtyard, even you and me, has been infected with abdominal pain, It's just that our source cultivation is relatively high. The epidemic virus has no substantive effect on us, right? "

Cao Hong affirmative way: "should be like this, right!"

White old man smell speech long sigh: "this can be really troublesome! There are too many viruses and poisons that can be counteracted by the source force. If we only rely on this, we will not be able to find out the main cause of this epidemic What shall we do next? We have to find out the ultimate source of the epidemic, right? "

Mr. Cao snorted coldly: "since we can't confirm the type of the epidemic virus, we can only find the source of the epidemic... But this is also the most troublesome part! You all have a good think. What can be the way to cause such a large-scale epidemic in Wanghai city? "

As soon as Mr. Cao asked this question, the whole house fell into silence. No matter Mr. Bai or Mr. Cao Hong, they dare not easily determine the answer.

After a while, it was Mr. Cao who took the lead in saying, "according to my idea, if we could make Wanghai city up to Cao's courtyard and down to the common people infected with abdominal pain, then the most likely thing to be used by the enemy is water."

"Wanghai city is located on the shore of the sea, but the only fresh water source for the whole city is the Haihe River flowing through Wanghai city! As long as the Haihe River is polluted, do the wanghaicheng people who drink the Haihe River worry about the epidemic? "

After listening to Mr. Cao's analysis, Cao Hong and Mr. Bai couldn't help looking at each other. Then, Cao Hong stepped forward and said to Mr. Cao: "grandfather, although your grandson also admits that what you said is reasonable, please don't ignore a very important factor! That's the liquidity of Haihe River! "

"Anyone who has a little common sense knows that if you want to poison people, water is the first choice, and stationary water is the best choice! For example, well water, small lake water, reservoir water and so on, because these water sources have one of the most significant characteristics, that is static! Only a static water source can preserve the poison thrown by the poisoner, and effectively distribute the effect of the poison to form an epidemic situation! "

"But the situation of Haicheng is far from simple! The part of Haihe River flowing through wanghaicheng is relatively small. In addition, the river surface of Haihe River is very wide. It is more appropriate to say that it is a river than a river. This leads to the high flow rate of Haihe River! If you want to poison the whole city in such a Haihe River, it will flow into the endless sea within half an hour as soon as the poison is thrown into the Haihe River! How can this cause such a huge epidemic area to achieve the unique purpose of poisoning people? "

"Hong'er is right!" Old man Bai took over the conversation and said: "most of the things that involve poisoning to create an epidemic are related to the water source. However, because of the particularity of Haihe River, it's really difficult for us to get involved in the epidemic in Haicheng Lao Cao, do you think it is possible to start from the source of food? Or, let's make a bold guess. Will the enemy use poison like "dispersing with the wind" and stand at the top of Wanghai city to spread it into the city

Mr. Cao thought about it very seriously, then shook his head and said, "impossible! Let's talk about the source of the food first! Food is different from water. Water is high or low. The whole city of Wanghai is drinking water from Haihe River! There are delicacies, vegetables and fruits in the food. Rich people eat better, but poor people eat less! Most of the ordinary dishes are produced in the suburbs of Wanghai City, while some other precious ingredients need to be transported by caravans farther away! Different sources make it difficult for the enemy to poison food. Even if the enemy is really cornered, poisoning food will definitely not cause such a large-scale epidemic situation! "

"As for the possibility of spreading drugs like" suifengsan "in the city in the windward, it is even lower! Don't forget that Wanghai city is close to the endless sea. The sea breeze from the sea has influenced Wanghai city for almost a long time! In such an environment, isn't it more difficult to inject the air borne poison "suifengsan" than to inject it into the Haihe River? The first gust of wind you put the medicine out, the next gust of wind will directly blow the medicine away I'm afraid only a fool would choose such a method? "

The white old man frowned and said, "it doesn't work, it doesn't work! Is this man really a God? Otherwise, how can this seemingly impossible thing be accomplished? "

After a round, the three of them didn't analyze the reason, which made them all feel depressed. After more than ten minutes of silence, Mr. Cao patted the table and said to Cao Hong, "we can only take a step at this time! Hong'er, go to the water treatment plant outside the west city immediately and transfer out the water treatment report from yesterday's daytime to today's daytime! Take a look at the water quality there is no obvious change! At the same time, you go to the Huichun hospital and invite Dr. Chang sun to the Cao mansion! In the name of doctor Chang sun, he should be able to find out the real virus more easily

Cao Hong was slightly stunned and asked Cao Laozi: "grandfather, it's no problem to go to the water treatment plant to get the water quality report, but it's going to Huichun hospital to ask the eldest grandson doctor... Aren't you afraid that the enemy hiding in the dark took this opportunity to find out the pregnancy of linger's younger sister-in-law?..."

With a wave of his hand, Mr. Cao said firmly: "now the situation is urgent. We can only take extraordinary measures! The epidemic situation caused by the enemy's use of drugs poses a difficult problem for us. If we keep doctor Chang sun, the most powerful doctor, out of use, it will make the enemy hiding in the dark suspicious! Anyway, doctor Chang sun's source power cultivation is quite low. Even if he stays in Huichun hospital, he won't help to protect ling'er and his children. In this case, it's better for him to come to Cao's courtyard and lead the doctors of Bai's family to see if he can find out what kind of poison the enemy is throwing as soon as possible, So as to cut off the source of the epidemic fundamentally! "

After the explanation of Mr. Cao, Cao Hong immediately realized that he was right Then he ran out of the room in a hurry and did as Mr. Cao ordered!

Here, Mr. Cao and others are at a loss, and the Huichun hospital is also very busy!

As the doctor with the highest medical skills in Wanghai City, the eldest grandson, who is known as "miracle doctor", is naturally the first choice for the people after they get seriously ill! Huichun hospital is also the first hospital full of patients!

More than a dozen doctors and more than 50 medical and nursing staff in Huichun hospital are very busy! Everyone's hands, there are several patients need to take care of, eldest grandson disease-free clinic door, even a long line up!

Fortunately, Mr. Cao has long predicted this phenomenon. First, let Cao Hong send someone to inform Hong Xiu that Chang sunling must not contact patients. Otherwise, I'm afraid Chang sunling, who is pregnant now, will resolutely join the front line of diagnosis and treatment of patients!

Listening to the painful wails and noisy cries in the front yard, Chang sunling's pity as a doctor arises spontaneously. However, Chang sunling also knows that his responsibility is to ensure his own safety and the safety of the baby in his belly! So even if Chang sunling wants to rush out to cure and save people, he still tries to control himself and doesn't take a step! This makes Chang sunling's heart suffer from pain and remorse all the time

Fortunately, Chang sunling was accompanied by red tea, which made Chang sunling find a support. The two sisters comforted and encouraged each other and faced the difficult test together!

Kanaka, who has been guarding at the gate of changsunling, has already entered the state of stealth. As long as there are suspicious people who dare to approach changsunling's boudoir, Kanaka doesn't mind killing, blood splashing five steps!

Just in this chaos, a horse team composed of more than a dozen people galloped out of Cao's courtyard, whipped all the way through the crowded street to the gate of Huichun hospital.

Then, under the leadership of the old man, these ten people turned over and got off the horse, stood in two rows, followed the old man and entered the Huichun hospital!

As soon as the reception staff of Huichun hospital wanted to ask about the origin and purpose of these people, they saw that the old man turned his hand, and he did not know where he took out a gold token with the word "Cao" clearly engraved on it! In front of the reception staff of the hospital.

At the sight of the token, the receptionist trembled and dared not say a word more. After bowing deeply to the dozen people, he quietly stepped aside.

With the help of the receptionists, these ten people went all the way to changsun's disease-free clinic! Came to the changsun disease-free clinic door, the head of the old man gently waved his hand, his more than a dozen hands quickly scattered, completely blocked the door of the clinic!
