A sudden attack on evidence may seem to panic the opposing lawyer, but in practice, the judge usually gives the opposing lawyer a certain time to reply. In order to leave a good impression on the judge as much as possible, my usual practice is to check the authenticity of evidence that can be checked in court. For other cross-examination opinions, I will apply to the judge for post-court verification and submit a written cross-examination opinion separately.
In some cases, the evidence submitted by the raid must be examined in court, and the judge has to announce an adjournment because it needs to give the opposing lawyer some time. Not to mention the time of the judges in the grass-roots courts. Precious time, which could have ended in one trial, drags on and easily annoys the judges.
