Am I a bad person? They all want to kill me?

Istaru snorted coldly and said, "How can I not know the art of concealment?"

The next second, Istaru merged into the shadow under his feet and turned into a shadow that seemed real.

Immediately afterwards, the shadow quickly moved behind Lin Qing'an and merged with his shadow.

Seeing this, Lin Qing'an narrowed his eyes slightly.

He still couldn't be sure of the specific strength of this Demon Lord.

But there are really many methods, including space equipment, teleportation-like movement, strong control of blood-colored wind blades, and hiding by shadow...

"correct......"

Just as he was thinking about it, Istaru suddenly popped out from Lin Qing'an's shadow.

"If you want to prevent others from betraying you, the best way is to sign a contract. I have a lot of blood contracts here. Do you want any?"

040. "The Good Friday of Erina Nakiri"

Lin Qing'an was slightly tempted, but when he thought about how proactive Tsuchimikado was, he became hesitant.

Tsuchimikado had already knelt down on his own initiative, but he still wanted to use a blood contract to restrain the other party. Wasn't this a bit too much?

"My Lord! I am willing to sign a blood contract!"

Hearing Tsuchimikado's weak but extremely firm tone, Lin Qing'an was no longer distressed.

You agreed to this yourself, I didn't force you.

Afterwards, Lin Qing'an took the blood covenant parchment from Istaru and signed a contract with Tsuchimikado and his party.

According to Istaru, a blood contract is several levels lower than a soul contract, but for humans, violating the terms of the contract is enough to cost them their lives.

By the way, these blood covenant parchments are not free!

One hundred human souls per blood contract, no bargaining accepted.

There are nine people in Tsuchimikado's group, nine blood contracts, and nine hundred lives.

It was natural for Istaru to ask for it, and Lin Qing'an agreed without any burden, while Tsuchimikado, who had signed the blood contract, lowered his brows and no one knew what he was thinking.

.........

At noon on May 5, Lin Qing'an returned to the Sigong family with a murderous look on his face.

After entering the mansion, Lin Qing'an went straight to Hayasaka Ai's bedroom, caught Hayasaka Ai, who was still lying in bed in the middle of the day, and gave her a good scolding for two hours.

Afterwards, he summoned six people including Shinomiya Kaguya and Nakiri Erina and gave them collective education.

At night, Lin Qing'an appeared in the study as usual.

He sat at his desk, tapping the surface with his index finger.

"Istaru, are you there?"

Lin Qingan suddenly asked.

"..."

There was silence, no one responded.

Through the soul contract, Lin Qing'an could roughly feel that Istaru was in the study. He thought about it and said.

"I want to discuss something serious with you, something about conquering the world."

With barely perceptible footsteps, Istaru walked out from the shadow of the bookshelf.

"You'd better come to me and talk to me about business."

Istaru crossed her arms across her chest and looked at Lin Qing'an with disdain.

Lin Qing'an didn't care about Istaru's mood. After thinking for a moment, he asked.

"Istaru, if you demons want to appear in the human world on a large scale and in an organized manner, what conditions must be met?"

Seeing that Lin Qing'an was really talking about business, Istaru suppressed his unnecessary emotions and answered seriously.

"Two conditions. One is to open a formal 'door', and the other is to have enough contractors."

"I don't need to explain much about the contractor. You can understand that without the contractor, we demons can't stay in the human world for long even if we enter."

"As for the 'door'..."

"I think you should be able to understand the meaning of this word alone."

"There are two ways to open the door."

"First, use the 'Devil's Son' to open the door."

"The so-called 'Devil's Child' is actually the child of a human and a demon. They are natural 'gates'."

"But unfortunately, 'Devil's Son' is extremely rare. I'm afraid it's difficult to find a 'Devil's Son' in the human world today."

"Even if you are lucky enough to find one, it depends on its strength."

"If I were as weak as an ordinary person, I'm afraid I wouldn't be able to support the opening of the 'door' at all."

"The second method is to use a large-scale blood sacrifice ceremony to open the door."

"As for the number... at least 100,000 people, there is no upper limit."

"Okay, I'm done, it's your turn."

Istaru crossed her arms and stared at Lin Qing'an with interest.

Compared to the Lin Qing'an who was invincible in bed, she still admired the Lin Qing'an at this moment more and was more willing to communicate with him at this moment.

Because only in this way would she feel that the soul contract was not signed in vain.

Lin Qing'an did not respond immediately. He took out his cell phone and checked the number of US troops stationed in Japan.

All in all, there are about 3.5 people.

Minus the US troops stationed in Japan, there is still a shortfall of 6.5 people.

There are so many candidates, including serious criminals, gangsters, and social scum in prison. It shouldn't be a problem to get 6.5 people together, right?

Thinking of this, Lin Qing'an put down his phone and asked.

"How many demons can a 'gate' of 100,000 people let in? And how long can it last?"

Istar narrowed his eyes and said, "If the 'door' is opened, we in the demon world can pay a price to keep it open, but the premise is that the 'door' on your side will not be destroyed."

"Destruction..." Lin Qing'an thought thoughtfully.

After a while, he looked up at Istaru and asked, "Does the 'door' have physical properties that can be blown up by conventional weapons?"

Istar thought for a moment and explained, "You can understand it this way. A door is divided into two parts: the door frame and the door itself."

"Through sacrifice, we will open a passage that can travel between the two worlds. This passage is the main body of the door. It will not be affected by the technological weapons of your human world, but the world itself rejects the existence of the passage. It will continue to squeeze the entrance and exit of the passage until it is closed."

"In order to avoid this situation, we need a 'door frame' to protect the passage."

"The 'door frame' will be stuck at the entrance and exit of the passage, bearing the pressure of the world on the passage. As long as the 'door frame' is intact, the door itself, that is, the passage itself, will not be affected."

"This 'door frame' has the physical properties you mentioned, and will be destroyed by your technological weapons."

"In addition, the material of the 'door frame' is very special. Once the 'door frame' is destroyed, its fragments will fall into the passage, causing the passage to close in a very short time."

After listening to Istaru's extremely detailed explanation, Lin Qing'an tapped the table lightly with his index finger.

In this case, the location of the door is very important.

We must ensure that the so-called "door frame" will not be easily blown away.

"Knock---knock---"

While I was thinking, there was a knock on the door.

"Who?"

Lin Qing'an asked subconsciously.

"Lord Qing'an, it's me. I have prepared the dinner you requested."

Erina Nakiri's voice came from outside the door.

Lin Qingan: "Erina, come in."

"Hey~"

Istaru curled her lips in dissatisfaction, turned into a shadow, and disappeared into the darkness.

"Click---"

The next second, the study door opened.

With a look of fatigue on her face, Erina Nakiri slowly walked into the study with dinner in her arms. Behind her, Hisako Arato, who also had a tired face, followed closely.

After Erina Nakiri put the dinner on the desk, Lin Qing'an waved slightly, and Erina Nakiri immediately understood.

She bit her lip and reluctantly sat in Lin Qing'an's arms.

Based on her experience of the previous few days, she was going to suffer again.

Alas, God's Tongue...

Unexpectedly, her tongue, which she was most proud of in the past, became the source of all her troubles at this moment.

041. "Although a forced melon can quench your thirst,... "

Lin Qing'an put his arm around Erina Nakiri's slender waist and looked at the dinner on the table with interest.

The dishes cooked by Erina Nakiri are very consistent with the ordinary people's stereotype of high-end dishes. The presentation of each dish can be called a work of art, but the portions are extremely small. A dish can be finished in two or three bites at least, and seven or eight bites at most.

Fortunately, there are many dishes, so it is no problem to eat enough to fill yourself up.

"Come, introduce these dishes you made to me."

Lin Qing'an gently patted Erina Nakiri's waist.

Erina Nakiri bit her lip and reluctantly introduced them one by one.

"This is 'Glazed Drunk West Wind Crab', a dish I modified based on the cooking method of 'Cooked Drunk Crab' from Jiangsu and Zhejiang regions of China. The crab is the 'Golden Crab', a specialty of China. When cooking, first... then... finally..."

“This is ‘Fruitwood Roast Duck’, also a Chinese dish…”

“Black beef cubes with mint...”

"Green pepper shrimp..."

“Seafood fried rice...”

Looking at the exquisite dishes on the table and listening to Erina Nakiri's detailed explanation, Lin Qing'an felt a little emotional.

As a time traveler from the Celestial Empire, he actually likes food very much, but in reality, due to factors such as money and time, he spends most of his time just replenishing his nutrition as a routine and rarely thinks about eating something good.

But now...

Naturally, one should never tire of fine food and delicious delicacies, and enjoy them as much as one can.

"Good, Erina, you put in a lot of effort. What reward do you want?"

After Erina Nakiri finished her introduction, Lin Qing'an asked with a smile on his face.

"award......"

When she heard the word "reward", Erina Nakiri's body unconsciously softened. An indescribable numbing feeling rose from her lower abdomen and quickly spread to all parts of her body.

“No… no need…”

With her pretty face slightly flushed, Erina Nakiri stammered and refused.
