The gathering of patients and the emergence of masks have delayed the spread of the disease.


    After a thorough investigation on the third day, most of the patients in the Imperial City have been isolated.


    Ten miles away from the Imperial City, an empty city has begun to be vacated. It is expected that these patients will eventually be sent there for centralized control. After all, it is always inappropriate to stay in the imperial city with healthy puzzles.


    The whole imperial city was busy, but there were no figures of Li Tai and Li Ke.


    After the two princes sent their staff, they took their family members and went to their villa to thank the guests behind closed doors. They announced that they wanted to summon famous doctors in the countryside to discuss strategies for diagnosing and treating diseases.


    Whether true or false, Li Zhi can''t stand idly by.


    Finally, he begged again and again, got the permission of the king of the Tang Dynasty and cooperated with Yuchi Jingde to build a shed in a barren mountain outside the Imperial City as the last place for the experiment.


    During this period, all supervision and care matters are fully supervised and controlled by two people.


    More than 300 people in armor stood quietly at the foot of the barren mountain, waiting for a lecture.


    Yuchi Jingde, who was headed by Yuchi Jingde, dressed in bright armor and holding a Tang Dao in his hand, straddled a tall horse, glanced at the neat square array and roared.


    "Keep the order! Doctor sun and his party will test the poison here today. The ban can''t be lifted until the red flag is lit in the roof on the top of the mountain!"


    "In the meantime, my eyes are wide open! If you let someone go or break into someone without authorization, your head on your shoulder will have to move!"


    Three hundred soldiers, armed with spears, drummed the ground pestle and responded in unison.


    "Obey the general''s order!"


    With Yuchi Jingde waving his hand, three hundred soldiers scattered. In a moment, all the main roads in the barren mountain were blocked.


    Towards dusk, a carriage from Marquis''s house came slowly.


    Yuchi Jingde greeted Li Zhi and stopped a hundred steps away.


    "Dingbei Hou, it''s hard!"


    Tang Hao opened the curtain of the carriage and stood in front of the carriage to talk back.


    "General Yuchi, there are still doctor sun and three prisoners in the car, as well as clothes for prisoners with sores. It''s not convenient for me to wait for you to talk about the past."


    "When the sun rises in this valley, we are drinking and chatting!"


    Li Zhi took the reins and took a step forward slowly, with a worried face.


    "Sister and son-in-law, in the shed, dry food is complete and water is sufficient."


    "You... You must come out."


    The ignorant youth of the past now know that sharing their worries for their father and facing difficulties is a good start.


    Tang Hao waved.


    "I''ve been in the imperial city and protected by others. Now that I''m under the command of general Yuchi, I''ll study hard and broaden my horizons."


    "Don''t worry about me."


    "Farewell!"


    The traffic continued slowly, winding up through the mountain road.


    The house is not big. It is several feet square. The humble roof can even shine in some places. A circle of fence around it is the activity range of five people in the next week.


    Tang Hao specially ordered his soldiers to block the main road down the mountain with boulders, just in case, in order to bring clothes covered with Xenopus virus.


    After vaccinating against cowpox, you will not catch Xenopus, which is just what Tang Hao knows. In later generations, smallpox has long been eliminated, so it can not be verified.


    At this time, he returned to this different time and space and made a verification. Tang Hao knew nothing about the symptoms in the experiment.


    Today''s situation is no better than that of later generations. There are not so many disinfection instruments and so many testing equipment.


    The only thing we can do is to reduce personnel contact and reduce the spread of the virus. In such an environment, we can verify whether vaccination against cowpox works.


    Standing on the top of the silent mountain, Tang Hao saw the simple environment and felt the waves in his heart.


    The ignorant are fearless.


    Like Sun Simiao, they don''t know the terrible reproduction of this pathogen. Naturally, they won''t have so many concerns in their hearts.


    But he is different. He is very firm in his mouth, but he is still playing a drum in his heart.


    Throughout history, millions of people died of smallpox virus at home and abroad.


    It is absolutely impossible to say that you have no fear and confidence in such a virus that has reaped millions of lives.


    Turning back, the three prisoners looked at the clothes in the glass jar, wondering what they were thinking.


    "Don''t be stunned. Time is pressing. Let''s start quickly!"


    Tang Hao knew his physique was different. He took the lead in opening the pottery pot and taking out those clothes. His heart still trembled.


    Emboldened, he wiped the clothes back and forth on his hands to comfort the three uneasy prisoners, said.


    "Our experiments these days are waiting for today''s verification."


    "Think more, for your freedom."


    I will not elaborate here.


    A single body of freedom has attracted these prisoners enough.


    "I believe in Marquis! If you are alive, you can do something for Datang at the last minute, and you will live up to being a Tang man!"


    A prisoner stood up, quite bloody, picked up his clothes and rubbed his face, which seemed to be a bit like death at home.


    Sun Simiao stood up slowly, straightened his spine and smiled.


    "I admire the northern Marquis for doing this disease personally. He is really a model doctor all over the world!"
