98 Tube Babies

The age difference between Nan Hua and Nan Xian Mu was very short. So short that most ordinary people would not be able to understand the reason. For them, it was inexplicable that a sibling could be born with such a short difference in time.

But for the people in Green Planet, it was surprising but not rare.

There were several other people with the same situation.

Nan Hai Yan and Lin Mei Yu didn't have children through normal means. They were using in vitro fertilization, a method to fertilize an egg outside of a woman's body. All they need was to take out what they need from a woman and man's body.

Once it was fertilized, it would be brought inside a woman's womb again.

The latest time before it was brought inside again was several weeks. If it was not brought inside, the fetus will die.
