Need to abstain for a company after joining on 1st day

Hi good day all just need a advise on below :-- I have joined an IT MNC and didn't like the quality of job and I also have a better offer in hand I just have attended the induction session on day one and officially just worked here for a day . My question is if I leave / abscond by informing them that I won't be working from tomorrow ( I don't need their relieving letter as just worked for a day ) and I join another organization so will there be any bad consequences like dual employment or something . Please help it's urgent
