Welcome to the Happy Village in the Spiritual Realm of the Great Universe!

After Lu Bao followed the refugees into Gaoping County, he was soon transferred to live deep underground. At first, he didn't feel anything special, but was very curious about this environment that was completely different from the ground. But before long, he discovered the abnormalities of the civilians around him. They first had disordered work and rest, then decreased appetite, physical weakness, and then mental depression. Some of the serious ones even had auditory and visual hallucinations, and even went crazy. Half a year later, even Lu Bao himself felt that he was in a trance from time to time. This situation immediately reminded him of a caveman tribe he encountered when he was wandering outside before, and they also had similar symptoms.

He guessed that this was mainly because the underground could not receive any sunlight or moonlight. Due to limited conditions, some places with better conditions could place a fluorite in their residence to illuminate it, but most people were basically in darkness for a long time. This was completely contrary to the laws of human life. If this continued, it would be strange if people did not get sick.

After coming up with this idea, Lu Bao, a man of action, immediately got busy. With the various rare materials he had collected over the years and his superb refining skills, he quickly made a "sunlight lamp". As the name suggests, a sunlight lamp is a spiritual lamp that imitates the brightness and temperature of sunlight and releases light. The main component of the lamp is a volcanic stone that absorbs enough solar energy. Through clever design, it can be activated and nourished with fire-attributed spiritual power, and it can continuously emit warm and bright sunlight. He placed this sunlight lamp at the entrance of the cave where he was, and it instantly illuminated the area within a hundred meters. People around him looked at it strangely and came to see it. The magical thing is that from then on, no one in the vicinity had any strange diseases.

Seeing that his invention was effective, Lu Bao made a "moon lamp". The principle was similar to that of the sun lamp. He used moonstone as the core of the lamp. After being activated with water spiritual power, it could release light exactly like moonlight.

Soon, more and more people came to Lu Bao to "borrow light", so he decided to promote this method. So he found the county magistrate Gong Hong and recommended himself. Gong Hong was very worried about this matter. When he heard what Lu Bao said, especially when he mentioned that no one in the neighborhood was sick, Gong Hong's eyes lit up, and he hired Lu Bao as a guest refiner in Gaoping County without hesitation, specializing in making "sun lamps" and "moon lamps". Lu Bao was also very open and immediately disclosed the production method to several refiners. With everyone's efforts, the two lamps were immediately popularized.

From then on, the underground world was no longer as dark and cold as before, but just like the ground, with sunrise and sunset, and the waxing and waning of the moon. Soon, the name of Master Lu Bao spread quickly among people, and everyone knew that Gaoping County had produced a great inventor, bringing good news to everyone.

Lu Bao lived up to everyone's expectations. Seeing that his inventions were recognized by so many people and could play such a great role, he was so happy that he couldn't stop inventing underground windmills, underground irrigation devices, underground defense facilities, underground swimming pools, and even underground amusement parks and underground medical clinics... Thanks to him, the people of Gaoping County can live and work in peace and contentment while the outside world is in the midst of war and suffering. Even though they are a thousand meters underground, their lives are almost the same as on the ground. Lu Bao has lived here for nearly ten years, and the population here has tripled!

Later, the old lady of the Lu family was really worried about her most beloved grandson, and she insisted on getting him to go home. Lu Bao had no choice but to agree. When he was leaving, all the people of Gaoping County volunteered to see him off, and some young people even followed him closely. Of course, Lu Bao couldn't let the people take risks, so with the help of Gong Hong, he got rid of the crowd, activated the teleportation talisman and left. Not long after that, he was sent to Tianlan by the old man in the family to be a teacher, and stayed there for more than ten years. He was not happy in Tianlan, but his father had given him a death order that if he dared to run around outside again, he would no longer recognize him as his son. He knew that his family was also considering his safety, so he endured it and spent his days in boredom. Until he met Yuan Ye.

"Brother Lu is a great benefactor to all the people in Gaoping County! Without Brother Lu, even if we were not affected by the war, we would have died of disease sooner or later, and we would not have the peaceful days we have today!" Gong Hong said gratefully, and once again apologized to Lu Bao.

"Teacher Lu, you are capable of such a great feat. It's really admirable! Come, let me toast you!" Yuan Ye and Hua Zhenbang were both passionate people. They immediately toasted with Lu Bao one by one.

The meal lasted a long time - in fact, it was mainly to listen to Gong Hong talk about Lu Bao's various wonderful ideas, and to watch the adults toast one cup after another. When the meal was about to end, Yuan Ye finally said a key sentence: "I want to take the children to the underground memorial hall to visit and study later. I wonder if it is convenient?"

"Hahaha, what's the inconvenience! From now on, as long as the former dean and all the teachers and students of Cangyu College are willing to come, we welcome them at any time!" Gong Hong's voice was loud and her words were particularly open. So, the after-dinner entertainment activities were happily decided.

Gong Hong personally served as a tour guide and took everyone from Cangyu to visit the underground. In fact, Yun Bai had no specific idea of ​​how deep one thousand meters underground was. But when they took the suspension ladder from the ground to the underground little by little, she felt it firsthand - it is estimated that ordinary people would be oppressed by the thick soil on all sides just to come here. Not to mention facing the cold and darkness. It was not until then that Yun Bai slowly understood why Teacher Lu Bao was so loved by so many people.

Along the way, Yun Bai was simply amazed. At first, she was protected by Xiaohua and Zhao Hongshan in the middle, fearing that it would be dark and gloomy underground, but when they arrived at the place, they found that their imagination was simply too poor - there was no difference between what they saw and what they saw on the ground! Rows of neat cave-like houses, not narrow streets, all hung with soft lights, exactly the same as the sunset outside! Next to the residential area is the commercial area. Although there is no one now, the various shops next to each other are still silently telling the lively scene at that time. Further in is the spiritual medicine hall, school, and amusement park, which have all kinds of facilities, making Yun Bai dazzled! Further in is the spiritual field, which has a complete irrigation system that can even automatically adjust the humidity and temperature! This is a small block, and there are thousands of similar complete blocks in different locations underground!

"Teacher Lu, you are so amazing!" Yun Bai admired from the bottom of her heart, and saw Lu Bao smiled shyly again. Then he came close to Yun Bai and whispered to her: "Teacher, are you okay? Otherwise, would you consider becoming my student?"

"Don't even think about hitting on Xiao Bai!" Two voices rang out simultaneously. Lu Bao looked back in surprise and saw Yuan Ye and Meng Qingchun's unfriendly eyes. He was immediately startled... And they didn't notice that not far behind them, He Youhong's pretty face flashed with a cold expression...
