Some days afterward, Remi gave birth to a son whom they named Menggin or Meng. Immediately after the birth of their son, Rukok told his family that he wished to return to his own homeland, because all of their enemies had surrendered. He told them that Sampar was old enough to become their leader in his place. Before he left them, he taught the Iban to observe strictly the following rules:
1. No one is allowed to commit adultery
2. If a man commits adultery with the wife of a war leader, he is to be fined fourteen jabir, which is equivalent to $14.00 and the woman is to be fined the same.
3. If a man commits adultery with a well known warrior’s wife (bini manok sabong) he and the woman are to be fined 12 jabir, which is equivalent to $12.00 each.
4. After a person’s death, the wife or husband of the deceased is to be known as balu, widow or widower.
5. If a person has sexual intercourse with a widow or widower it is a great sin called butang antu. The offenders are to be fined in accordance with customary law.
6. No widow ar widower may remarry until after his or her deceased spouse has been honoured by the payment of a small fine made to the relatives of the deceased, later given back, in a ritual called ngambi tebalu mata’ within about six months; or ngambi tebalu mansau after the feast of Gawai Rugan or Gawai Antu.
7. If a widow has sexual intercourse with a widower, it is a great sin, berangkat antu. The offenders are to be fined in accordance with customary law.
8. Any person marrying a widow or a widower is also committing a great sin, also called berangkat antu. They are to be fined heavily too.

10. When a man marries a woman, her family must always demand a marriage fee from him, called the bunga pinang.
Before he finally left for his own homeland in the spiritual world, he then begged them to look after his son as he was growing up. Menggin grew up, half-human half-demon, during the peaceful era after the Kantu-Iban war. He was an adventurous person and known to be able to travel between human world and the domain of Iban God of War, Sengalang Burong, at Tansang Kenyalang, a daughter whom he met and married and begot a son named Sera Gunting. Their adventures will be told in another chapter of this article.
