Second Half of Chess Board

Chess was invented by Seeza during the rule of ghuppta family rule in sub-continent and with its invention a very interesting story is related....seeza went to the king with the game of chess,king liked game and gave seeza the right to name his prize for the invention.....seeza thought for a second and asked my lord"some grains of wheat"...king asked what do u mean?seeza asked my lord,fill the squares of chess with grains but according to my formula which is that for the first square of the chess board, he would receive one grain of wheat , two for the second one, four on the third one,eight on fourth on and so on, doubling the amount each time untill the last 64 column. The ruler, arithmetically unaware, quickly accepted the inventor's offer, even getting offended by his perceived notion that the inventor was asking for such a low price, and ordered the treasurer to count and hand over the wheat to the inventor.....when the mathematicians of king reached at the end of fourth row the wheat of grains in whole country got finished.....when the treasurer took more than a week to calculate the amount of wheat, the ruler asked him for a reason for his tardiness.treasurer explained that it would take more than all the assets of the kingdom to give the inventor the reward but they were unable to tell king exact amount of grains a 64 squares will take....this was approximated by Bill gates after 3500 years he says that if we put nineteen zeros in front of 1,this amount is the total amount of grains a 64 squares of chess will contain...according to bill gates if we put 1 billion grains in one container then we will need 18 billion containers to reach total amount and to count those grains we will need 2 million years......now what happens to inventor of chess seeza,well,when king reaches on fourth row he ordered seeza to arrest and further he was killed and that's how inventor of chess died.
