In truth, with the Han Tribe's current level of technology, the fastest way to transmit real-time information should have been using beacon towers. All they needed to do was add a flashing-light function to the existing beacon towers, and they could transmit Morse code across dozens of li.
However, this method had some obvious drawbacks. First, construction and maintenance costs were high. Second, it was completely useless during the day. No matter how bright the light was, it could not be seen in daylight.
Moreover, beacon towers were not suited to the current battlefield situation. Thus, after discussion, the bigwigs ultimately decided to use smoke signals to transmit information.
Smoke by day, fire by night.
The tactics and strategy had been finalized. Next came the tense relocation of the camp and training. The army outside the city broke camp and set up a new one three kilometers directly west of Kaiyuan City. The camp used wooden palisades as its defensive line, with several layers of chevaux-de-frise to guard against enemy cavalry raids. Several artillery positions had also been prepared around it in advance. No matter which direction the enemy came from, the Han Tribe could quickly maneuver and provide fire support.
The civilians in the outer city were also urgently moved inside the city walls. Everything that could be carried away was taken along. Fortunately, the herders had only joined recently and did not have much to take. The houses obviously could not be moved; if the enemy destroyed them, they could only rebuild them.
At the army camp outside the city, mounted scouts were dispatched every day to patrol the surrounding area and prevent surprise attacks. The Training Ground inside the camp also rang daily with booming cannon fire and the shouts of soldiers and cries of horses.
