The next day, Jiang Feng did not go to kill the mutant rats, but Su Xue knew very well that Jiang Feng needed this thing to promote the growth of mutant termites or blood forests, so she took the initiative to lead the team to another mountain range to clear out the mutant rats.
Just like yesterday, it only took them half a day to bring back a large number of mutant rat corpses. They used the same method to deal with them, digging out the crystal cores and collecting them, and then throwing the corpses into the Blood Forest.
This large-scale cleanup of mutant rats lasted for about a week. The mutant rats in the nearby mountains were likely to become extinct. The blood forest had now grown thicker than a bucket, and after turning into vines, it could completely cover the entire castle. The mutant termites had also all matured under the cultivation of a large number of crystal cores.
At the same time, the turtle grew to nearly fifty meters long after continuously swallowing a large number of strange fish.
When everything is ready, the expansion of the castle can officially begin. The blueprints of the castle have already been drawn up by those technicians.
After Jiang Feng saw it, the parts he was not satisfied with were modified, and the entire castle was designed to look like a steel fortress.
It is larger and more defensive than previous castles, and the various areas are divided more detailedly. A special fighting room has been added above the original supporting pillars on the top floor, and the top floor is also closed. However, the ceiling above the botanical garden can be moved to both sides to open up an open-air area for plants to absorb sunlight.
Jiang Feng plans to use an unprecedented method for this construction.
In the first step, Jiang Feng asked Anna to scan the drawings, build a three-dimensional model, and then calculate the amount of metal materials used. Then he asked Anna to simulate the specific steps of expanding the castle, divide the stages, and deal with the parts connected to the original castle.
Then Jiang Feng asked the ant king to lead the ant colony to search for a place with more iron elements nearby. Soon, these little guys used their talents and abilities to find a mountain with a high iron content.
Then Jiang Feng let the turtle crawl over and used the earth-based ability to control the soil and rocks on the mountain. The mutant termites that could control metal also began to use their abilities to gather the iron elements in the soil and rocks under the command of the two golden termites, and then extracted them and gathered them into pieces of iron!
The whole process was carried out in a very clever manner under Jiang Feng's command. A large amount of earth, rocks and mud turned into an earth dragon and rushed down from the mountain. The iron elements carried in these earth and rocks were easily separated by the mutant termites using their special abilities and turned into pieces of iron lumps when passing through the queue of mutant termites.
The whole process was simply shocking. The earth dragon's huge, winding body leaped down from the mountain and became a pile of small hills again under the control of the turtle. At the same time, a large number of iron blocks appeared out of thin air in front of everyone. This made some technicians open their eyes wide for fear of missing any details. This method was simply a stroke of genius!
Because even in modern society, blast furnace ironmaking requires a lot of work and a long time of smelting to obtain iron blocks.
When the amount of iron blocks was enough to expand the castle, Jiang Feng quickly stopped the turtle and mutant termites. Although the efficiency of superpowers was much higher than that of humans, Jiang Feng still spent most of the day controlling the mutant beasts to hollow out half of the mountain before getting enough metal materials. If he had not prepared enough crystal cores to replenish their energy, it would probably take some time to complete the task.
After getting enough metal materials, Jiang Feng immediately asked the people who had been watching the show for a long time to move all the metal blocks to the turtle's back, and then let the turtle move again and return to the base!
After returning, Jiang Feng did not start expanding the castle immediately. Instead, he fed some crystal cores to the mutated termites to let them recover for a while, as they would be needed to contribute later.
After about an hour, the mutant termites had almost recovered, and the entire expansion really began. Jiang Feng commanded the large number of mutant termites in the ant colony through the ant king to manipulate the metal to build the walls of the castle.
During this process, other people must also go up to help, because Jiang Feng alone cannot take care of all places in the castle.
Their main task was to help carry the metal blocks next to the mutant termites, and at the same time act as Jiang Feng's eyes to pay attention to the progress of the project. When there was something wrong, they would promptly inform Jiang Feng. After they were fully prepared, Jiang Feng began to complete the steps calculated by Anna step by step, processing the foundation, softening the metal to build the wall, and then slowly increasing the height of the wall.
When the walls reach a certain height, the first floor of the castle is basically completed, and then the construction of the ceiling above begins. This step requires embedding metal into the original castle walls.
When the ceiling was completed, Jiang Feng opened a door on the second floor from the original support column to the outside. From here, the metal could be moved up here, and then the construction of the castle wall could continue. However, shooting holes would be set up starting from the second floor, and then the third floor.
The third floor is mainly built with a battle room. A dome-shaped battle room is built on the top of each supporting pillar of the castle. Inside the battle room is naturally a crossbow. The entire battle room can be rotated left and right according to the direction of the crossbow. There is a vertical opening facing the outside. The main purpose of the battle room is to prevent the crossbow from being damaged by rain and to protect the safety of the combatants.
There was an experience before where a soldier almost fell from the castle.
Each battle room is connected by a corridor, which is also prepared for battle. There are a large number of shooting holes on the walls, and hundreds of people can attack the entire castle at the same time.
