How long did Grandfather stay when he met again?

Ancestors stayed for 3-7 days.

Players can find it during this time and spend candles and hearts in exchange for the items of the copy ancestors. You can get extra wings of light during the copying process. After 3 days and 20 hours, the ancestor of the replica will disappear, but the exchanged items will not disappear. So players need to spend time exchanging what they want. If they miss it, they may have to wait for a year.

Light Encounter is a social adventure game developed by game producer Chen Xinghan and his team Thatgamecompany. Operated by China Netease Game Agency. In the game, players will be incarnated as "descendants of light", bearing the will of their ancestors, and hand in hand with friends to launch an adventurous journey on this wonderful continent of Sky Kingdom.

Game story:

The story begins with a hazy morning light. The newborn descendants of light in Chenguang Island, like ignorant children, stumbled on an adventurous journey. Strolling in the clouds full of spring, crossing the humid and lush rainforest, racing on the gorgeous ice in summer and summer, fighting with ghost dragons in the cold dusk, and exploring the truth of the lost kingdom in the forbidden pavilion ... Travelers shoulder the mission of bringing light back to to the sky kingdom step by step, and come to the last stone gate to prepare for the challenge of the eye of the storm.

On the way through the eye of the storm, strong winds and boulders came face to face, and travelers had to walk hard while avoiding the ghost dragons hovering overhead. Guided by the brightest starlight in the distance, the travelers reached a narrow tunnel, and the stone lampstands on both sides and the wings of light scattered on the ground seemed to indicate the extreme danger at the end.
