"After these children in artificial wombs are born, I want to study the unknown substance in your body, is that okay?"
Suddenly, Song Pinxuan asked.
Tang Li was stunned upon hearing this.
Then she smiled and said, "I forgot to tell you. The unknown substance in my body has already been developed."
Song Pinxuan was surprised to hear Tang Li's words, "It's already developed?"
Tang Li nodded, "Yes, but the cost is very high."
"I'll give you a tube for research. See if you can find a synthesis method to save costs."
There were 3 research pods on the fourth level of the G City underground city.
These 3 research pods were not just for show; they were naturally meant to be utilized.
And the Z Nation and R Nation researchers brought back by Tang Li from D City, who had invasive brain-computer interfaces installed in their heads, also had their own uses.
Even Xu Zhenhua, who had an invasive brain-computer interface installed, was contributing his remaining expertise in the research pods on the fourth level.
These individuals with brain-computer interfaces installed were all extremely loyal to Tang Li.
Except for a small number like Lu Wan, who had public residences on the upper three levels and private homes on the fourth level, most residents of the G City underground city were registered as hidden households, staying on the fourth level and never venturing out.
Tang Li naturally entrusted some research tasks that she deemed important to them.
The unknown substance within her body was, of course, a top priority.
As early as February last year, shortly after moving into the G City underground city, Tang Li had drawn a tube of her blood, made many copies, and handed them over for research.
After 10 months of research, these researchers on the fourth level had long since extracted the unknown substance from her body.
However, they had not yet figured out what kind of substance it was.
As for artificial synthesis, it was even more impossible.
But even so, Tang Li still copied a large amount of her blood from her spatial storage and gave it to the researchers on the fourth level to extract the unknown substance.
Finally, a tube of pale yellow-white crystal was extracted.
This color was the same as the jade pendant that had given Tang Li her spatial ability.
After Tang Li stored it in her spatial storage, the energy consumed for replication was also very large.
The energy consumed to replicate an unknown substance the size of Tang Li's jade pendant was equivalent to about 1000 cubic meters.
Moreover, Tang Li had also had people experiment.
These crystals could not synthesize the jade pendant, and when others dripped blood on them, they could not gain access to the replication space.
However, whether it was used by someone or dissolved into a solution and injected into the human body, it could enhance human physical strength, mental power, and improve people's training efficiency, healing ability after injury, and the five senses.
The more it was used, the more obvious the improvement.
Tang Li referred to this unknown substance as "X substance."
By drawing blood from the bodies of people who had used the first-generation X substance, the second-generation X substance could be extracted.
Using the second-generation X substance to a certain extent could also achieve the effect of enhancing physical strength, mental power, the five senses, and so on.
However, the amount of second-generation X substance required was enormous, so much so that it was necessary to drain all the blood and flesh from the body of someone who had used the first-generation X substance to meet the requirement, and the effect was still not as good as the first-generation X substance.
After listening to Tang Li's explanation, Song Pinxuan nodded in agreement with Tang Li's suggestion.
"By the way, the gestation period for the children in the artificial wombs should be due soon, right? When do you plan to have them born?" Tang Li asked.
Song Pinxuan smiled and said, "The children are adapting well in the artificial wombs, so we'll let them be born at full term. It should be in the next few days."
Tang Li heard this and said, "Then after the children are born, I'll give you a tube of X substance."
