"It seems that this meeting was a success, and I am very glad to have met you." Canglan sighed, but didn't notice that what she said seemed a little ambiguous.

"I never thought that I would meet my fellow countrymen, the four joys of life, and the old acquaintances in other places." Pei Mengqing also sighed.

"Not only did I get to eat the food from my hometown that you made, but I also got the opportunity to return to Earth to see my mother fulfill my filial piety, and I also regained the motivation to cheer up and continue my cultivation, all thanks to you." Canglan was still emotional, and her gratitude to Pei Mengqing was beyond words.

Such a great monk thanked himself like this, Pei Mengqing was still a little embarrassed.

However, Canglan began to yawn again, obviously after such a long period of consumption, the time of accumulation was up.

Just like the giant of light in a certain M78 nebula, the light on his chest starts to flash, indicating that he is going to zoom in.

"Well, we'll have to see you next time, I hope you're doing well on the ground, and next time I should be able to recover somewhat, so don't worry about the duration of my stay next time."

After saying this, Canglan yawned endlessly, so Pei Mengqing didn't say more, no longer resisted the re-appeal of the body, and chose to return.

However, Pei Mengqing was not in a hurry to wake up from his cultivation state, but took advantage of the effect of the Soul Nourishing Pill to continue his cultivation.

The progress was very fast, much faster than he expected, and he might be able to complete his soul cultivation realm before he fully manufactured the thermometer and completely used countless of these things to measure the lowest point of temperature.

Estimating the "central point of the severe cold" of the task description of the cultivation system, Pei Mengqing estimated that after finding it, it was the location directly below where the cold winter beast was sealed.

Perhaps, when he went underground these times, the underground space would also be in that location.

There is no process for his spirit to return, and there is no sense of direction or other definite angle of traction.

Therefore, there is no way to judge the exact location of the underground space from this point.

However, it is already certain that the center point is not where the Skyscanner Sword is located.

When he went to the central area, Pei Mengqing saw the Sky Patrol Sword.

The blade of the sword was stuck in the earth, and only the sword grid was stuck in the dirt.

Probably because the people of Yanzhou University were afraid that the sword would not be able to see a shadow when it was sunk in the soil, so they specially put two blue bricks on both sides of the sword grid......

As for why it was not the center of the cold that was able to be cut straight away, it was because when Pei Mengqing arrived next to the Heavenly Scanner Sword, the cultivation system did not remind the task to be completed.

Therefore, the task identification of the cultivation system is also a method to find the center point of the severe cold.

However, it is impossible to let Pei Mengqing go to every corner of the entire Tianhe County to "trigger the prompt" through this method.

The area of Tianhe County is not small, and it is a different concept to walk through a section of the road and go to every corner of the city, Pei Mengqing did not take so long to complete this matter.

Therefore, it is better to rely on the thermometer to be reliable.

The principle of the thermometer is not difficult, there is a magic method, and the manufacturing process is not difficult for those in the research institute.

They just chose the wrong medium to measure temperature at the beginning, and chose "water" with a somewhat unusual coefficient of thermal expansion.

With mercury, it is believed that they will soon be able to produce a finished product and find a standard.

The problem was how to mass produce.

The good thing about this era is that many of the crafts that were difficult to do with the technology of his original earth can be done through supernatural forces such as magic.

But the problem is that the original earth can, as long as there are molds and production lines, mass production can be easily realized.

And mass production does not exist in this era.

Perhaps even the glass (glass) shell of the thermometer has to be rubbed by hand.

I just don't know how many of these warlocks can rub at a time, if they can rub dozens of them at a time, then maybe a few dozen times will be enough......

During this time, Pei Mengqing had a rare leisurely time.

The zombie crowd outside the city cannot move for the time being, and the people of Yanzhou University are still thinking about how to "use waste".

The organization behind Yangzhou Slow is sending people to investigate, and the two captives brought back have also said everything they can say, and now they are in shackles that can limit the use of strength as coolies.

The progress of waste utilization has not yet been seen, and I don't know what kind of research the warlocks from Yanzhou University will do, anyway, Pei Mengqing saw that they had caught a lot of zombies and brought them into the laboratory.

As for the city, Li Liangcai's guy is conscientious, every time a zombie appears, he can rush to eliminate the signs of crisis as soon as possible.

Pei Mengqing himself followed Li Yucai to take a swordsmanship class, went outside the city to chop wood and collect food, and practiced at night, and lived a very fulfilling and relaxed life.

During this period, Dongfang Xiaoyu's graduation thesis was finally completed and submitted to the school, and soon after the thesis inquiry, she successfully graduated and is currently working as a teaching assistant in the university temporarily.

However, the school is discussing that this matter should be reported to the state and county level and even the state pastor, and see if it can be given to Pei Mengqing and Dongfang Xiaoyu and the two orange cats...... And Li Liangcai is trying to get some benefits.

Dongfang Xiaoyu and Pei Mengqing both said that they could use their names to keep up with the people with research talents, or simply ask for some funds to accelerate the research of the zombie groups outside the city.

It is best to complete the "waste utilization" as soon as possible or eliminate them all, so as not to make it impossible for the residents in the city to get out, and there will always be an outbreak of zombie viruses that will cause panic among the people.

It's just that with the passage of time, it seems that it is about to reach the spring of March, but it is still cold.

The thermometer was successfully built, and there were also warlocks from the research institute who helped build thousands.

Pei Mengqing scattered the thousands of thermometers in different locations in Qingzhu District, and then transferred them to other districts.

And uphold the rigorous comparison, will strive to simulate the environment of the weather louver box, so that the interference of other external factors as much as possible.

Things like air humidity, wind speed, sunlight reflections, etc., are all as uniform as possible.

Thousands of positions are placed for three days at a time, and then the middle of a certain period of time is taken.

Finally, presented on the data sheet collected by Pei Mengqing, removing some data with large errors, Pei Mengqing found that the closer to the city wall, the higher the temperature, and the closer to the central area, the lower the temperature.

The overall trend is that the closer you get to the center, the cooler it gets.

So you can preliminarily lock down, and the "cold center" is in the central area.

It's just that it's in the center of the central district, or whatever.

During this period, Pei Mengqing also tried to investigate the central point of the seal, but there was too little news, and few reliable ones failed.

In the end, we still used the stupid method to continue to use these thousands of thermometers to "divide into blocks", and finally narrowed down the target area according to the trend.

When the results came out, Pei Mengqing found that the center point of the so-called severe cold was where the institute was located......
