As far as the eye can see, there are wide plains.

Thirty condemned prisoners were tied to wooden stakes in rows, each spaced about ten meters apart, their eyes covered by strips of cloth, their mouths gagged with rags, and their whole bodies bound and unable to move.

Alan and Dinah, standing under the roof of the shed, watched the men who were about to be turned into giants.

They will use the power of the Ancestors to give orders to the giants who are about to be born.

Quite clear orders, in Allen's hands, there is a manual.

Giants are divided into three categories: giants for agriculture, giants for construction, and giants for mining areas.

The types of tamed giants that need to be tamed today are these three for the time being.

Each type of giant requires different instructions and dimensions to be implanted.

For example, for building giants, sometimes it is necessary to build tall buildings, and it is necessary to build bridges under deep ravines, and the giant needs to have a high height.

Giants for agriculture and giants for mining areas need more strength.

The size of the giant is a difficult variable to control, so they are classified according to the height of the giant after its transformation.

Taller than 12 meters can be tamed as a building giant, and below this height can be used for other purposes.

It took Eren a long time to learn before he understood what Ian meant, and he learned to use the power of the Ancestors to implant instructions for these Unsullied Giants.

It wasn't an easy thing to do, and what Ian asked him to do was not to give orders to the giants and make them listen to humans.

In fact, the plan has been improved several times, and at the beginning, it was decided to appoint a person in charge for each giant, using the power of the Ancestors, so that the giant would obey the orders of the person in charge.

After all, Eren is only one person, and if he wants to use giants to build factories everywhere, he can't do it all.

But there are many drawbacks to this solution, such as whether the person in charge can be trusted?

What if the person in charge has a conflict with someone else, gives an order to the giant, and kills someone?

What if the person in charge passes away in an accident? Do you want Alan and Dinah to go to the area where the giant is used again and rebind the person in charge?

After careful consideration, he gave up the idea of being in charge and turned it into the current one, classifying the division of labor for the giants and implanting special instructions.

For example, Alan now wants to tame a group of Unsullied Giants into agricultural giants.

Then he first has to implant several "classes" for this group of giants: [Start Standby], [Loosening the Soil], [Sowing Seeds], [Harvesting Crops], [Carrying Crops], [Moving], [End Action], and so on.

To trigger the giant's action, you need some special signals, like a remote control, using the sound of a special whistle and human movements to command the giant.

When an agricultural giant is tamed, it becomes a machine-like thing that only reacts to instructions that have already been implanted.

In their underlying logic, there are several that are the highest, such as not being able to attack humans, not being able to leave the prescribed range, and so on.

Such a giant can be sent to any agricultural area, and as long as he learns how to control it, he can command it to move.

Not only can it greatly improve productivity, but it can also prevent it from being used for things other than agriculture, avoiding accidents, and it is much more practical than the "person in charge" at the beginning.

The only drawback is that it is more cumbersome to tame, because some of the instructions are quite complicated, especially in architecture, and in response to different construction situations, the number of instructions has been increased to dozens.

The construction workers are still giving feedback, and the instructions in the future will become more and more complex and more precise, and there may be many small branches from the construction giants.

This part of the first tamed giants is for trial and error and experimentation, and in order to make the giants become flexible "large machines" in various fields, it is necessary to continuously improve the mode of its operation.

When the mode is almost mature, it is time to tame and classify the large number of giants outside the walls of Maria.

Of course, that time is not yet there.

What we need to do now is to try to run the giant labor force first, and take advantage of this time to quickly survey the resources of iron ore, coal mine, ice blast stone and other ores, plan the area, and determine the course of action, and then put the giant outside the wall into production.

It is estimated that there are about 10,000 giants outside the wall, and each giant can become a "machine" that does not require energy, is powerful, and is not afraid of damage.

"So... Let's get started. Ian gave the order.

"Yes." Hannes nodded.

He took out his flare gun and aimed it at the sky.

With the sound of gunshots, the soldiers removed the seal of the wooden box under the watchful eye.

In the wooden box, the silver-white spinal fluid potion revealed a dreamlike light.

The soldiers followed the procedure and injected the needles into the blood vessels of the prisoners' necks, and before the golden lightning lit up, they used a three-dimensional mobile device to leave.

Thirty giants, tall and short, appeared in the vast fence.

Alan took a deep breath and took Dinah's hand.

The Unsullied Giants were restrained, frozen in place, scattered, and lying flat on the ground.

Next, the soldiers took a tape measure to measure the height of each giant, and the statistics were sorted out.

Giants above twelve meters were the first to stand up and line up, then five to ten meters tall, then five to ten meters taller, then five to five meters lower.

Alan took the manual and walked with Dinah to the twelve-meter giant.

He has done this very skillfully.

For the others, it was only a moment, but he entered that strange space.

The place full of sand, his spirit, was connected to the six twelve-meter giants.

He was full of only one thing, and implanted the command into the giant's instinct.

"Don't overthink it, just do what Ian says..."

"It's the only thing I can do..."

He looked into the distance, the girl with a bucket of sand.

"Don't think about anything, finish what I can!"

"As long as we keep moving forward, we can reach the other side of freedom!"

He calmed down and modified the giant's mode of action.

After the first giants were tamed, he left the coordinates and tested the operation of the giants here as construction workers who had participated in the battle for the recapture of Maria.

The worker blew his whistle and directed the giant to move forward, then to stop, and told the giant to lift the steel bars and transport the stones...

Then there's the accidental test, where the giant puts obstacles in its way and tests how it reacts to building materials, livestock, and humans.

All tests are carried out under the control of the power of the ancestors.

It went smoothly, and the giant coped with all kinds of emergencies perfectly according to expectations.

This group of construction giants, tamed successfully, was handed over to the construction workers to be taken to the nearest iron ore area to build an iron-making factory.

There is no doubt that they are developing at a speed that is impossible for the outside world to recognize.
