Apart from receiving these reinforcements, they had to gather the Army at River City and send the civilians away in batches. Some of the civilians went to other cities to seek refuge with their relatives and friends, while some chose to go to the bewilderment city.
In fact, Zhao Hai and the others had to thank Wu Tianci. If Wu Tianci hadn't given them these few days, they wouldn't have been able to calmly make arrangements and send all the civilians away. The reinforcements from the various city-states wouldn't have arrived so smoothly either. Of course, Zhao Hai and the others weren't naive enough to think that they would be at ease once the reinforcements from the various city-states arrived. In fact, the battle had only just begun when the reinforcements arrived.
