After signing the magic contract with all the thunderbirds, William patted the leader of the thunderbirds with satisfaction, "Is your usual food just ordinary meat, or do you have to eat magical creatures?"
"Gah, gah, gah".
There was an exchange of ideas, and from the answer of the Thunderbird leader, William estimated that their daily food intake was about one-tenth of their body weight in meat, and there was no need to deliberately pursue whether they were magical creatures.
It's right to think about it. It's impossible for all magical creatures to eat food from magical creatures. Since meat is enough, this is too simple for William.
Although adult thunderbirds are more than three meters tall and have a wingspan of about fifteen meters, they, like all raptors, look very big but are not as heavy as land animals.
Adult ptarmigans generally weigh only about 200 to 300 kilograms, and eat an average of 25 kilograms of meat a day. 76 of them are 1,900 kilograms, which is less than two tons of meat a day.
Moreover, they also eat the internal organs of animals, so there are only 6 to 7 adult beef cattle per day.
On the 35,000 acres of land attached to Oxford Castle, some are grassland to raise cattle and sheep. Raising tens of thousands of cattle is enough to provide sufficient food for the ptarmigans.
The purchase cost of tens of thousands of cattle, plus the subsequent hiring of people to herd them, is only tens of millions of pounds.
This amount of money is almost the same as the money spent every year on the blood horses raised in the castle horse farm. You can just sell a few tons of gold to get the cost back.
The only thing that worries William is that once animals adapt to feeding, their wild nature will weaken.
After a few generations, they may not even know how to hunt, and they may become afraid of mice like domestic cats.
However, William then thought that it would only be a few years or more than ten years before these Thunderbird descendants appeared and grew up.
The worst case scenario is that within a few years, the newly born Thunderbirds will be returned to this planet, or to Planet X17 for a period of time, and let them hunt on their own.
Perhaps in the future, as the number of Thunderbirds increases, some individuals can be released to Planet X17 to breed and become members of their own monster army.
However, since he does not have to follow him to England, William still has to ask the Thunderbird leader what he means, "Are you going to live in my territory, or will you continue to live here and accept my call when I need it?"
"Gah, gah, gah".
I thought that the Thunderbird leader would at least think about it, but I didn't expect that it didn't hesitate at all. Instead, it impatiently agreed to follow William.
While this made William happy, he also understood that these thunderbirds were creatures at the top of the food chain.
But living in a dense forest, too many trees have seriously hindered their hunting. Life is not as good as imagined, otherwise they would not be robbing King Kong of food.
Now that he has a master, and he seems to be very powerful, of course the Thunderbirds will want to follow him.
"Very good, you can move around freely for now. After I have taken care of other things, I will summon you and take you away together."
"Quack, quack, quack", the Thunderbird leader nodded obediently, and then, under William's surprised eyes, he called out to King Kong, who had been staying by the side.
If he hadn't signed a magical contract with the thunderbirds, William would never have imagined that these guys would rely on numbers to threaten King Kong to help them hunt.
Faced with dozens of pairs of eagle eyes staring at him, King Kong, who had suffered the electric shock from the Thunderbird, no matter how bad-tempered he was, he did not dare to have other thoughts. Instead, he knew that he would not be in danger, so he whined happily.
Then under William's stunned eyes, he dragged out from the hidden place in the valley the Tyrannosaurus Rex that had been stabbed by its neck yesterday but was not dead for a while.
Nm, if King Kong hadn't dragged out the Tyrannosaurus rex, William would have forgotten about it. Moreover, this big guy is quite good at hiding things, so many thunderbirds flew over and he didn't even notice it.
Seeing that King Kong was helping the Thunderbirds dismantle the Tyrannosaurus Rex, William told the Thunderbird leader not to bully King Kong, and then flew into the sky, following Sunday's instructions, and flew in the direction where Elf Bell escaped.
With so many thunderbirds needing human hands to take care of, William, who had never trusted humans, suddenly became interested in house elves, a creature that in his opinion was absolutely ugly.
As long as he raises a dozen elves, he will definitely be able to take good care of the thunderbirds.
And William even wanted to know the origin of the person named Christine whom Elf Bell spoke about.
William, who was not flying at full speed to avoid alerting the enemy, took only half a minute to fly out of the forest and quietly arrived in a valley more than 300 kilometers away.
"Are you sure you're here?"
Looking down at this valley full of flowers and plants from a height of several hundred meters, William scanned it several times with his mental power in confusion.
But I didn't find any suspicious places, and even more beautiful saw any humanoid creatures, footprints and buildings left behind after their lives.
"Sir, you need to fly about one kilometer further into the valley. The spacecraft's detector shows that there is a very weak energy source here, which is expected to be a shield with a stealth function.
But this protective shield should be on the verge of collapse, so the spider on the bell can keep transmitting the signal to me."
After flying several hundred meters, William's mental power immediately detected a weak energy fluctuation. Unfortunately, before he could figure out whether it was an invisible energy shield or some other energy source.
After a violent fluctuation of magic, dozens of various magics seemed to appear out of thin air, flew out from the energy shield a hundred meters away, and focused on him.
This kind of magic that can see the flight path is too easy for William, who can fly hundreds of kilometers per second, to avoid it.
But he didn't dodge directly, but wanted to let the magic elves inside understand the difference in strength, avoid unnecessary casualties, and avoid being unable to hire them after they formed a feud.
An idea flashed, and ten Sentinel armors that had absorbed the magic power of the dragon Snugger instantly appeared ten meters in front of William.
Then the hand holding hands transformed into a golden city wall, blocking these dozens of magic attacks and at the same time absorbing those elemental magics as energy.
As for entities, magic such as rocks and ice cones hit the Sentinel wall. They didn't even make the wall shake before they shattered and fell.
After all the magic was blocked, under William's command, the city wall was deliberately transformed into the appearance of five nearly three-meter-long X-type sentry robots that looked scary and mighty, with guards suspended in the air surrounding William.
"I'm here to see an elf named Bell. There is some misunderstanding between us. Maybe we can sit down and talk?"
Unfortunately, after saying this, he was greeted by a more violent magic attack.
