After signing the magic contract with all the Thunderbirds, William patted the Thunderbird leader with satisfaction, "Is your usual food just ordinary meat, or do you have to eat magical creatures?"

"Quack, quack, quack".

There was an exchange of thoughts, and from the words of the leader of the Thunderbirds, William estimated that their daily diet was about one-tenth of their body weight, and they did not need to deliberately pursue whether they were magical creatures.

It's also right to think about it, it is impossible for all magical creatures to have to be magical creatures for food, since meat is fine, this is too simple for William.

Adult ptarmigans are more than three meters tall and have a wingspan of about fifteen meters, but like all birds of prey, they look big and weigh not as much as land animals.

Adult ptarmigans generally weigh only about 200 to 300 kilograms, and eat an average of 25 kilograms of meat a day, and 76 heads are 1,900 kilograms, which is less than two tons of meat a day.

They also eat the internal organs of animals, which makes them only 6 to 7 adult beef cattle a day.

On the 35,000 acres of land attached to Oxford Castle, some of the grass is used to raise cattle and sheep, and tens of thousands of cattle are enough to provide enough food for the ptarmigans.

The purchase cost of tens of thousands of cattle, plus the subsequent hiring of people to graze, is only tens of millions of pounds.

This amount of money is almost the same as the annual cost of those sweaty horses raised in the castle horse farm, and the cost of selling a few tons of gold will come back.

The only thing that worries William is that once the animals get used to feeding, they will weaken their wildness.

After a few generations, you may not even know how to hunt, and you will turn your head to fear mice, like a domestic cat.

However, William thought again and again, when these Thunderbird descendants appear and grow up, it will be a few years, more than ten years later.

It's a big deal that in the next few years, the newborn Thunderbird will return to this planet, or planet X17, for a period of time, and let them hunt by themselves.

Maybe in the future, the number of Thunderbirds will increase, and some individuals can really be released to the X17 planet to multiply, so that they can become a member of their own monster army.

However, since it was not necessary to follow him to England, William still had to ask the leader of the Thunderbirds what he meant, "Do you go to live in my territory, or do you continue to live here, and accept my call when I need it?"

"Quack, quack, quack".

I thought that the leader of the Thunderbird would at least think about it, but I didn't expect it to hesitate at all, but agreed to follow William with some impatience.

This made William happy, but at the same time, he understood that these ptarmigans were even creatures at the top of the food chain.

They can inhabit dense forests, and too many trees have seriously hindered their hunting, and their lives are not as good as they imagined, otherwise there would be no robbery of King Kong's food.

Now that they have a master, and it looks like it's not good, of course the Thunderbirds will have the idea of following.

"Very well, you wait here to move freely, and when I finish taking care of other things, I will summon you and take you away with me."

"Quack, quack, quack", the leader of the Thunderbird nodded very obediently, and then in William's surprised gaze, he called out to King Kong, who had been honestly staying aside.

If it weren't for the magic contract with the Thunderbirds, William really wouldn't have imagined that these guys would rely on numbers and threaten King Kong to help them hunt.

Facing dozens of pairs of eagle eyes staring at him, King Kong, who had suffered from the thunderbird's electric shock, no matter how irritable his temper was, he didn't dare to have other thoughts, but understood that he would not be in danger, and whined happily.

Then, under William's stunned gaze, from the hidden place in the valley, dragged out the Tyrannosaurus rex that was intended by it to neck yesterday, but did not die for a while.

NM, if it weren't for King Kong dragging this Tyrannosaurus rex out, William would have forgotten about it, and this big guy's ability to hide things is not small, so many thunderbirds flew over and didn't even notice it.

Seeing that King Kong was helping the Thunderbirds dismantle the Tyrannosaurus Rex, William told the leader of the Thunderbirds not to bully King Kong, so he flew into the sky and flew in the direction of the elf bell to escape according to Sunday's instructions.

With so many ptarmigans to take care of, William, who had never believed in humans very much, suddenly became interested in house-elves, which in his opinion, were absolutely ugly creatures to death.

As long as he raises a dozen elves, he will definitely be able to help him take good care of the thunderbirds.

And William wanted to know what the hell was the origin of the man named Christine in the mouth of the elf bell.

William, who was not flying at full speed, only took half a minute to fly out of the forest and quietly came to a valley more than 300 kilometers away.

"Are you sure it's right here?"

Looking down at this valley full of flowers and plants from a height of several hundred meters, William scanned several times with his mental power in confusion,

But I didn't find anything suspicious, and it was even more beautiful to see any humanoids, footprints and buildings left after life.

"SIR, you'll need to fly another kilometer or so into the valley, and the spacecraft's probe has revealed a faint source of energy, presumably a shield with stealth capabilities.

However, this shield must be on the verge of collapse, so the spider on the bell can keep the signal to me."

After flying a few hundred meters, William's spiritual power immediately swept a faint energy fluctuation, but unfortunately before he could figure out whether it was an invisible energy shield or something else.

After a violent fluctuation of magic, dozens of various magic spells flew out of the energy shield a hundred meters away as if they appeared out of thin air, and bombarded him in a concentrated manner.

This kind of magic that can see the trajectory of the flight is too easy for William, who can fly hundreds of kilometers per second, to dodge.

But he didn't dodge it directly, but wanted to let the magic elves inside understand the difference in strength, so as to avoid unnecessary casualties, lest he couldn't hire them after making a feud.

A thought flashed, and ten sentinel armors that had absorbed the magic power of the giant dragon Snug instantly appeared more than ten meters in front of William.

Then the avatar holding his hand turned into a golden city wall, blocking these dozens of magic attacks, and at the same time, he also absorbed those elemental magic as energy.

As for the physical ones, magic such as rocks and ice picks crashed into the sentry walls, and before they could shake the walls, they shattered and fell.

After all the magic was blocked, the city wall, under William's command, deliberately turned into five X-type sentry robots that looked terrifying and mighty nearly three meters, and the guards suspended in the air surrounded William.

"I'm here to find 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.
