Psionic Overlord

You're just an outsourced worker, and you want compensation? On the day he was kicked out, his gray badge suddenly heated up—【Ding! Photovoltaic Overlord System activated!】【Solar energy converted to spiritual energy, efficiency 1000%!】While others cultivate immortality by fighting over spiritual veins, he just lays down a few photovoltaic panels and has more spiritual energy than he can use! A household array multiplies spiritual energy within a hundred zhang by ten; a commercial array directly charges a spiritual vein within a thousand zhang! An energy storage array stores full spiritual energy to blast a sect gate flat at any time; a space array provides uninterrupted power around the clock! The sect thinks his aptitude is poor? He lays photovoltaic panels all over the ground, and the spiritual energy concentration becomes number one in the entire realm! A hostile sect invades? Once the energy storage array is deployed, a spiritual energy cannon blasts your sect gate flat! From outsourced trash to otherworldly photovoltaic overlord. Wherever sunlight reaches, there is spiritual energy! Whoever blocks my photovoltaic path, I'll wipe out their entire clan! Lin Chen stands before a ten-thousand-meter photovoltaic array, with a million cultivators worshipping behind him. This world will henceforth speak through sunlight. — Description from novelcodex.org
