Tang Li, with the children, took the passage from the second-floor simulation cabin two to the third-floor research cabin, went to the research cabin first, and then on the third floor, from the research cabin to the medium-sized residential cabin.
Here, Song Pinxuan, Tang Guo, Lin Xi, Xue Keyue, Peng Yixuan, Peng Yue, Zhong Heng, Bai Xunyang, He Yun, He Xiao, and others gathered.
Although nearly 20 years had passed, everyone looked much the same.
Peng Yue was sixty years old, but he looked no older than his early forties, perhaps even younger.
Tang Guo was already forty-seven, but she still maintained the appearance of her twenties.
Tang Li was forty-four this year, and she also looked young, as if she had returned to the age of eighteen.
This was also why Song Chaoyang had said earlier that Tang Li looked no different from Tang Chenxi.
Not only did their appearances not differ, but their ages also seemed to be the same.
Since the reverse-aging cell longevity serum was discounted each time and its effect was to make cells half their age, none of the children had used it yet.
After all, a thirty-year-old cell, after its first reversal, would become fifteen, a reversal of fifteen years. However, an eighteen-year-old cell, after its first reversal, would become nine, only a reversal of nine years.
Therefore, the reverse-aging cell longevity serum would only be used when the children were older.
At least after their cellular age reached thirty.
Moreover, cellular age and a person's actual age were not the same.
Cellular age could be older than a person's actual age due to lack of proper care, or it could be younger due to the use of aging-delaying longevity serums.
And before their physical development was complete, the children had not even used the aging-delaying longevity serums.
After all, the children wanted to grow up quickly and did not want to remain in their childhood appearance.
Therefore, eighteen-year-old Tang Chenxi, who had not used any longevity serum, was indeed eighteen years old.
After Tang Li used the reverse-aging cell longevity serum and continued to use the aging-delaying longevity serums, her cellular age was indeed no different from Tang Chenxi's. Kuai Shu Ge.
Coupled with the fact that Tang Chenxi looked almost identical to Tang Li.
Thus, to strangers, it was truly difficult to distinguish between mother and daughter based on their faces alone.
The banquet was abundant with food.
This food was not replicated by Tang Li from her spatial inventory but was produced by the underground city.
The G City underground city, after several expansions, was now capable of accommodating one million people.
The supporting energy cabins, storage cabins, breeding cabins, planting cabins, and industrial cabins, on the surface, were also designed for one million people.
However, the permanent population of the G City underground city was still less than 200,000.
Among them, the more than 60,000 children nurtured by artificial wombs over the past decade or so still resided in simulation cabin two, with the first batch scheduled to be assigned jobs next year.
The remaining less than 130,000 people lived in the residential cabins.
The residential cabins of today were also different from before.
When the G City underground city was first built, although the giant residential cabins could accommodate 100,000 people, each person had only a room of about 30 square meters, which was just a place to sleep.
Only the small and medium-sized residential cabins offered better living conditions, all being suites.
Now, the large and giant residential cabins had also been converted into suites and apartments, with areas ranging from at least 50 to 80 square meters.
Although the number of people who could live in each residential cabin had decreased, the number of residential cabins in the G City underground city had greatly increased.
This was especially true for the first floor responsible for production and the second floor responsible for public services.
All residences were allocated based on job assignments.
Of course, those willing to spend more积分 could also live in better accommodations.
In addition to the permanent residents of G City, there were also about 30,000 transient populations who frequently stayed in G City.
These people included those sent to work by the authorities, like Zhao Xiaoqing, staff members of the G City stations of the underground transportation network and their families, as well as those who came to G City to procure goods.
Even Xue Keyue's grandfather, among these high-ranking officials, had stayed in the G City underground city for a period.
And with a population of less than one million in the G City underground city, the products produced by the breeding and planting cabins that supported one million people naturally had a surplus.
The excess, besides being sold to official underground cities, was also cheaper for their own use.
Although the official underground cities were also expanding, they had too many people and limited resources, and they also needed to be used for global resource exploration, making it impossible for everyone to live the life of those in the G City underground city.
Their giant residential cabins still had capacity for 100,000 people.
Therefore, the people of the G City underground city were very fortunate to live there and had a strong sense of belonging.
And people from other official underground cities also yearned greatly for the G City underground city.
Especially since the G City underground city also had longevity serums and enhancement serums.
Although the prices were very high, in the G City underground city, if one could directly earn积分 coupons, it was possible to buy them eventually.
The money earned in official underground cities was difficult to exchange for G City underground city积分 coupons, and it was impossible to buy longevity serums or enhancement serums at all.
