When you open the link to see the page content click on the icon after the number increases by one. Check the js source code, there will be a content commit when clicks>=1000000. The flag should be available after submission.

Now the problem is how to make clicks>=1000000. Manual click is impossible, found visit http://123.206.87.240:9001/test/, the server will return the page content. We can use fiddler to intercept the response and modify the value of clicks.

First set the interception mode of fiddler.

Then refresh the page, intercept in fiddler, and change the value of clicks in response to 1000000.

Click the icon again, the value of clicks is 1000001, initiate submit, return to get flag, the problem is solved.
