Dhruv Jurel and Ravindra Jadeja hit attacking centuries to put India in total control with a lead of 286 against the West Indies in the first test on Friday.
KL Rahul led the batting show with his 100 before Jurel, who made 125, and Jadeja piled on the agony for the opposition bowlers in a marathon stand of 206 on day two in Ahmedabad.
India reached 448-5 at stumps in response to West Indies' first-innings total of 162.
Jadeja, on 104, was batting alongside fellow left-hander Washington Sundar, on nine, at close of play.
Wicketkeeper-batsman Jurel raised his first test ton with a boundary off West Indies skipper Roston Chase and the son of a war veteran celebrated with an army-like tribute with his bat.
Jurel took the attack to the visitors with 15 fours and three sixes before he became the first test wicket of debutant left-arm spinner Khary Pierre.
Jadeja plundered his sixth test hundred and raised the noise of a sparse crowd at the world's biggest cricket stadium with his trademark sword celebration. He hit six fours and five sixes.
The right-left batting pair of Jurel and Jadeja wore down the opposition bowlers on a deteriorating pitch.
A delivery from Jomel Warrican went past Jadeja at ankle length after hitting a rough patch formed due to bowlers' footmarks.
Warrican had Rahul caught at short extra-cover with his left-arm spin on the fifth ball after the lunch break. The opener did not trouble the scorers after reaching his 11th test century.
Rahul reached the ton in the morning session, kissing the India flag on his helmet and soaking in the applause from the few hundred fans sprinkled in a sea of orange seats at the 132 000-capacity stadium.
Starting the day on 121-2, Rahul and skipper Shubman Gill, who made 50, put on 98 runs to pile on the agony for the West Indies.
The two overnight batters had a few nervy moments.
Rahul survived a reprieve on 57 when an edge from his bat went between the wicketkeeper and slip in the first over.
Rahul, who started the day on 53, hit regular boundaries with his exquisite timing and technique.
Gill looked to find his mojo after a cautious start and reached his eighth test fifty with a single off Pierre.
The captain soon got out to Chase's off-spin after he attempted a reverse sweep but lobbed it to Justin Greaves at slip.
The West Indies have struggled in the absence of premier fast bowler Alzarri Joseph and Shamar Joseph – both ruled out ahead of the series with injury.
India are strong favourites to win 2-0 against an opposition that is a pale shadow of the team that once ruled world cricket.
