Why can Diga Altman only stay on Earth for 3 minutes at a time?

The country of light is very far away from the earth and has crossed the galaxy. Where is the sun outside the Milky Way? Moreover, it has been pointed out in Altman that there is no sun in the country of light. In the kingdom of light, only the Saiwen family can convert light into energy. Although Dicktia Dana and Gaia are giants of light on the earth, the energy they need is not light, but can enhance their strength through light. It is reasonable for Yuangu officials to set all Altmen as "only staying on the earth for about 3 minutes".

Altman will destroy many buildings and factories during the battle. If Altman fights monsters for a long time, the consequences are unimaginable, so Altman usually plays for about 3 minutes.

Actors who play giants and monsters need to wear seamless holsters before shooting. The leather case of this Ultraman monster is not only heavy, but also airtight. In order to make the leather actors well ventilated and reduce the number of shots, Yuangu set the plot to 3 minutes. However, the holster of the first generation Altman was greatly improved in the middle and late period. Until Saiwen Altman filmed and aired, the audience couldn't accept Altman's long battle story at first, so Yuangu changed back to Altman's idea of three-minute battle.

Why can you only take it for three minutes on earth? The reason is very simple. The pollution of the earth is very serious, and Altman can't replenish energy on the earth, which limits the time for Altman to maintain energy.
