Essence [Strategy] Art of War (Blue Team Edition) "Continued"

Level 3: My strategy is to handle it with defense towers without using a single soldier. First, build a power plant next to the main city. After the power plant is completed, build a defensive moat right beside the main city, then build a rocket tower at the black-edged location. Remember to enclose it, otherwise it will be destroyed by the enemy before completion. Then, build another rocket tower at the lower right of the first rocket tower, enclose it as well. When you have enough money, build a new main city next to the first rocket tower (remember to enclose it). After the new main city is built, build more power plants on the empty land below. Then, build a rocket tower above the new main city at a distance, and another one on the left. Remember to enclose the small road. After completion, build a new main city between the two rocket towers. Once this main city is built, build another rocket tower at a distance above it. Be careful of any enemy presence, it's unlucky if an enemy passes by at the same time (this rarely happens). Then, on the empty space of the original main city, build a few research institutes. After they are completed, select the tenth research option, which should be some kind of detector—it will be useful. Find a suitable position on the just-built rocket towers to build another main city (in the meantime, build two rocket towers beside it for defense). After all this, build a detector in a barely visible area on the left, and build a rocket tower on the small road at the upper left. Once completed, the rocket tower can attack the enemy's defense tower, and even if it gets hit, after destroying the enemy's troops, quickly build a few more rocket towers (although they get hit, it can still be done). Once successful, build rocket towers near the completed main city, keep building, and place detectors. Eventually, you will find that you can build a main city right next to the enemy's main city.

Level 4: Very easy, just take soldiers to attack the enemy's city. Here's how I do it: first destroy the front defense towers, then move the soldiers to the top area to attack. After that, there should be only seven or eight soldiers left, then move down to attack the bottom. The bottom part is easier, with only a few soldiers and towers. It will be destroyed very quickly. Pretty easy, right!

Level 5: It's a defense battle. Deploy 22 soldiers. First, move the stronger soldiers to the right, middle position, and the rest to the middle-bottom position. Then, build two main cities in the positions they left. Use the remaining money to build power plants (remember, power plants must be built). The enemy's attacking troops can be held off for a few turns. Once you have money, build five or six rocket towers below the new main city (recommended to enclose, and enclose at a distance). Do the same on the right side of the main city. Then, build a factory that produces machines for defense, followed by a research institute. Select the 14th research option (probably rocket vehicles or something similar). Produce these vehicles, move them to the tower side, press “5” to see several options, then press “7”. Produce a few more, ensure the surrounding area is well-enclosed for reinforcement. Pay attention, and you can clear the level easily. It's pretty straightforward.
