In about forty minutes, Xia Ruo treated all the patients he had sent.

Tan Chu also received a call from Lu Xu, and his face not only changed, but also looked ugly.

"Doctor Xia, Lu Xu couldn't find the source of the disease, they checked this area, and the water source and gas were tested, but no source of the disease was found."

"And now there are more people in that area who are getting sick."

Xia Ruo sighed: "Let's go over and have a look." ”

The source of the disease could not be found, and more and more patients were being sent in, and she could not treat it alone.

The treatment of these people requires the use of gold needles to force the diffused toxins into one place, and then drink medicine to cure them completely.

"Okay, let's go take a look!" Tan Chu also knew that Xia Ruo was too busy to save so many people by himself.

In order to reduce the number of patients, the source of the disease can only be controlled as quickly as possible.

Xia Ruo boiled the medicine first, and instructed the dean and others how to master the heat and when they could feed the patient, and then followed Tan Chu and the others to the area in a hovering car.

Fortunately, that area was not very far from the hospital, and they met Lu Xu after more than ten minutes.

Tan Chu saw Lu Xu's calm face and knew that there was no progress, "Have you all checked this area?" ”

Lu Xu nodded: "I ordered the people of the war group to separate and take the instrument to investigate, but there was no response, and the entire area has been checked." ”

Xia Ruo used the wood-based ability to perceive it, but he didn't find any abnormalities in his life.

After thinking about it, she took out some grass from the fairy and demon vines, compiled it into the shape of a small straw man, used her spiritual power to spend spiritual runes on the grass man, and took out the blood taken from one of the patients and stained it on the face of the grass man.

Tan Chu and the others looked at Xia Ruo with puzzled expressions, what was she going to do?

Then they saw Xia Ruo point the little straw man with his fingertips, and everyone's eyes suddenly widened, wondering if they were hallucinating.

I saw that the little straw man seemed to be alive, jumped off Xia Ruo's hand, sniffed around, and then ran in one direction.

"Keep up!" Xia Ruo quickly chased after the straw man.

Watching the straw man and Xia Ruo leave, Tan Chu and Lu Xu and others reacted, although they felt incredible, but they still quickly followed.

Soon, the little straw man came to a bustling street and kept jumping around a corner.

Xia Ruo walked over and saw a half-burned cigarette stuck in the wall in this corner.

Lu Xu and the others also came over at this time and asked in surprise: "This is the source of the disease?" ”

Xia Ruo squatted down and sniffed, "Yes, this is it!" ”

The person brought by Lu Xu immediately took out an instrument to test, "This cigarette contains a substance that is harmful to the body!" ”

Now everyone is sure that this is the source of the disease.

Lu Xu frowned and said, "I didn't expect them to light such a small cigarette in the corner of the wall, we drilled the tip of the horn before to find the smoke that could spread farther." ”

"The power of this cigarette is still powerful, such a small strand can't be seen without looking carefully, it can actually infect so many people with the virus." He then sighed.

Xia Ruo stretched out his hand and nodded at the little strawman, "Such a little bit will definitely not be able to spread on a large scale, let's continue to look for it!" ”

The cigarette was snuffed out by Lu Xu's people and put in a closed container, and the little straw man continued to look for it under Xia Ruo's control.

Subsequently, dozens of identical cigarettes were found in various corners of the area.
