An exploration made public
The Portuguese exploration of Luzon in 1545 by Pero Fidalgo and the Knowledge of Tomi Pires about Luzon in 1512 would be known in Portugal during the reign of John III of Portugal which would cause the Spanish to be blocked from acquiring Luzon up to 1580 when the Spanish took control of the Portuguese throne on 1580.
On 1570, After Legaspi would have discovered that Luzon is a part of the land called Selurong by the Borneans or Ysla de Luzon by the Spanish is divided to three lands of Sapa, Luzon/Comintan, and Ibalon and made relations with Lakandula of Tondo and Sulayman of Maynila and negotiated friendly relations with them and with the new Spanish colony of the Philippines, he knows himself that he would be forbidden to conquer any part of that area and did not try to conquer it as it would cause problems with the Portuguese under King Sebastian, the Spanish would establish trade posts and missions in the Kingdom of Tondo instead of conquering it.
The land of Sapa would also later be the Kingdom of Sapa/Selurong which claims the rest of Selurong due to its ties with the Bruneians who were ruling Selurong via Kandarapa of Tondo, a niece of Lakandula.
