so I make a zh_cn file for this mod.
You can add it if you wanted

{
"enchantment.tolaserblade.light_element": "光元素",
"enchantment.tolaserblade.light_element.desc": "在激光剑上稍微提升攻击伤害,并且对怪物和流浪者造成额外的伤害",
"item.tolaserblade.laser_blade": "激光剑",
"item.tolaserblade.laser_blade_fp": "激光剑",
"itemGroup.tolaserblade.general": "ToLaserBlade",
"upgrade.tolaserblade.fireproof": "燃烧抵抗力 8000"
}

Thanks for your translation!
I'll update the lang file in the next version.

I'm thinking of translating "upgrade.tolaserblade.fireproof" into "耐高温 8000". This is because the English translation "HEAT RESISTANT 8000" means that the laser blade can withstand a high temperature of 8000 K.
