In short, no matter how the dark knight Xiao Hei argues that he will definitely be able to get along with Gao Xiaomin, and will never kill Gao Xiaomin, it will still be taken away by Zhang Tong in the end, Zhang Tong said: You will obediently obey me, there are many things that you need help with in the future, of course, as compensation, it is also appropriate to follow Lao Tzu's side to eat and drink spicy food.

However, the money for raising Xiao Hei in captivity naturally needs to be paid by Xiao Min. Although Zhang Tong can also make money, this small restaurant can bring him tens of thousands of yuan every month, but it may not be enough to raise a dark knight.

Especially to maintain the strength of the dark knight and prevent his strength from declining too much, then Zhang Tong needs to feed a large amount of nutrients to this dark knight.

Because the rules are different. This place is the earth, not the Demon Realm, nor the Magic Continent, and there is no so-called Demon Spirit Energy to recharge the Dark Knight.

The only way for Xiao Hei to get energy is to eat.

However, the Dark Knight's stomach is unusual. As high-level demon species, their ability to adapt to the living environment is particularly strong.

If they don't have the familiar magical energy in their environment to replenish them, they will rely on their superior digestive power to absorb any food that enters their stomachs, and then convert it into energy to sustain their bodies through the transformation of food.

Of course, it is necessary to maintain the daily energy consumption of a high-level demon species, even if it is a low power consumption that keeps Xiao Hei in a standby state. (That is, it does not change into a demon form, does not use strength to fight, and just maintains daily expenses, and is as normal as a human walking movement.) The amount of time required each day is still a very large number.

If you want Zhang Tong to raise Xiao Hei, I'm afraid he can't afford it. And Zhang Tong didn't want Xiao Hei's strength to weaken. Because Xiao Hei's strength is weakened, then he will be useless, and at that time, he can really only chop up, roast it, and then throw it to the bottom of the Pujiang River.

I need Xiao Hei because I need Xiao Hei to help me do something. For example, when it's inconvenient for you to come out and pay for the jihadist organization or something. The Dark Knight's combat power is still considerable.

However, it is not easy to find a suitable energy source for Xiao Hei to replace the energy he consumes every day.

Because Xiao Hei is a high-level demon species, their bodies have special strengthening. They can absorb almost anything that goes into their stomachs and provides energy. From the most basic foods to bark and grass roots, anything you can think of that you can eat, even gasoline and other things that you can't eat.

In order to find the best feed to feed the little black properly. Zhang Tong and Gao Xiaomin had to spend a day finding all kinds of things from the market that could be eaten and could not be eaten, but could provide all kinds of energy and pour them into Xiao Hei's mouth.

"Here, let's try the beef first, Xiao Hei opened his mouth. Zhang Tong brought a plate of sliced boiled beef tenderloin to Xiao Hei, who raised his head and opened his mouth obediently: "Ah." ”

Snoring, Zhang Tong poured all the plates of white-cut beef into Xiao Hei's mouth, and Xiao Hei's super digestion and absorption ability began to start. In just a few seconds, this high-level demon had already eaten up a plate of one-kilogram white-cut beef.

Xiao Hei pouted: "The taste is okay." ”

"I didn't let you taste it, what I wanted you to feel was how much energy you had recovered. Gao Xiaomin motioned to Xiao Hei not to say what he had.

Xiao Hei thought for a moment: "Probably recovered a standard demon spirit energy. "Demon spirit energy is the universal unit of calculation of energy by the little black demon race, which is roughly equivalent to the caloric unit of kilocalories (or kilojoules) calculated by humans. An adult male needs about 1,200 to 1,500 kilocalories a day. As a high-level demon race, even if he enters an ultra-long standby state, Xiao Hei needs to ingest one hundred and twenty standard demon spirit energy a day.

This means that Xiao Hei needs to consume 120 kilograms of beef every day, and this is still boiled. You must know that beef will shrink when it is cooked, and if you buy fresh beef, it may take 150 kilograms to consume enough for a day.

"Beef pass, I don't have that much time to cook a hundred and fifty kilograms of beef for him every day. Zhang Tong passed the beef directly. And it's strange to buy so much beef every day.

So Zhang Tong and Gao Xiaomin changed to the next item, mascarpone cheese, a raw material for making mousse cake.

"Open your mouth. ”

"Ah~"

A kilogram of mascarpone cheese was poured into Blackie's mouth.

"How much energy was restored?"

"Well, about two and a half standard demon energy. Hei replied.

However, this is not scientific in terms of calorie formula, because mascarpone cheese has many more calories per 100 grams than boiled beef tenderloin, and four times that of lean beef. But Xiao Hei is a demon, and sometimes it can't be determined by science. Maybe there is some special energy in beef that humans can't detect, but demons can absorb it?

The mascarpone is okay, Xiao Hei eats about fifty-five barrels a day (a kilogram of mascarpone cheese). It's still a bit much, though.

Several foods were tested before and after, but the results were not satisfactory. So Gao Xiaomin took out a barrel of 98 gasoline that she went to buy today, and she said to Xiao Hei, "Open your mouth." ”

"Ah~"

Tons and tons of tons~, ten liters of gasoline barrels were by Xiao Hei.

"Hiccup~" Xiao Hei burped, and the whole room smelled of gasoline. Zhang Tong glanced at Gao Xiaomin and whispered, "Is it really good for you to give it gasoline?"

Gao Xiaomin waved his hand: "It's okay, don't cars also drink gasoline? And I bought a high-grade one, and other people's Porsches drink this." ”

Zhang Tong: What kind of logic is this?

"Oh, it tastes terrible. It's like drinking a trauma potion. My throat felt a little sore and it felt like it was burning. Little Black complained. Zhang Tong nodded in his heart: Yes, not only do you have a sore throat that seems to be burning, but now I can really burn a match.

"How do you feel?" Gao Xiaomin cared about this question.

"Well, a hundred standard demonic energy was restored. "Xiao Hei feels energetic. Maybe the demons can really move by refueling?

"Okay, I'll give you ninety-eight gasoline in the future. Gao Xiaomin happily made such a decision.

In the end, Zhang Tong was a little unbearable, what is the matter of drinking gasoline every day? In case my house is marked one day, who will it be? So under Zhang Tong's strong recommendation, Xiao Hei still tried some other things to replenish energy.

Finally, it was decided to use President brand salted butter as Xiaohei's charging product. Because this butter can provide Xiao Hei with no less energy than 98 gasoline. And the key point is that it tastes good. Especially after freezing, Xiao Hei said that the taste is particularly delicious, and eating it with honey is like eating ice cream.

So Xiao Hei's food standard on the earth was set, ten kilograms of salty butter plus 500 grams of locust nectar, and a few other foods. Calculating the price, the cost of feeding Xiao Hei for a day is almost a thousand. This is still Xiao Hei's super long standby state, if Xiao Hei is allowed to go out to do something, this consumption will rise exponentially. If there was no financial assistance from Gao Xiaomin, Zhang Tong really couldn't afford Xiao Hei's daily expenses.

After deciding on Xiao Hei's diet, there is another important thing.

Zhang Tong patted Xiao Hei and asked, "This appearance is not convenient in this world, can you turn into a human form Xiao Hei?" This is the most important thing for Xiao Hei to survive in this world (at least before sending it back to the Demon Realm). You can't wear this armor when you go out on Earth, right?

Xiao Hei nodded at Zhang Tong: "It's okay to turn into a human form?"
