Sixteen-year-old Lin Zheng had been practicing football for six years, but before the announcement of the Municipal Youth Cup roster, he was squeezed out of the starting lineup by a talented forward who had just returned to China. After a collision, he unexpectedly had an "echo field": after every official game, he could replay the ninety minutes he had experienced. It cannot predict the future, cannot make the body stronger out of thin air, and overuse can cause headaches and nosebleeds. So Lin Zheng could only bring the mistakes he saw clearly the second time back to reality and improve his abilities a little bit. From the last substitute of the school team to the professional youth training, national competition and national youth stage, what he wants to prove is not that he is more favored than the genius, but whether an ordinary forward can make the right choice time and time again and play well in his only first pass.
