How can I get the other party to reply to the message in seconds?

It is not a controllable thing to let the other party reply to the message once a second, because everyone's life and work have different busy levels and schedules. However, you can take the following measures to increase the probability that the other party will reply to the information in time:

1. Send concise and clear messages: express what you want to convey clearly in a concise and clear way, so that the other party can see at a glance, which can save communication time between both parties.

2. Use SMS or instant messaging applications: Sending information through SMS or instant messaging applications is more likely to attract the attention of the other party and get a quick reply.

3. Give priority to the right time: Send a message when the other party may be free and have nothing else to be busy. If you know when the other person usually reads the message, you can send the message at that time.

4. Give a specific question or request: Ask the other person a specific question or request directly, which can clearly express what help or answer you want and make it easier for the other person to reply quickly.

5. Offer help or advice: If you can offer help or advice, it may be easier to inspire them to think and reply to your message.

Please remember that even if you take the above measures, there is no guarantee that you will let the other party reply immediately. You should respect their time and personal life and be patient while waiting.
