"Yes," Wang Luli smiled, "Originally, it couldn't be made so easily, but last time I mentioned to Grandpa Kou that people without seals have the ability to protect themselves in the mirror, we had the idea of this thing." ”

"Yes, yes," Old Man Kou smiled excitedly, the wrinkles on his face became deeper, "The perfect combination of explosives/medicine and daytime crystal tubes!" ”

"Does that mean that people who don't have seals can fight against those who have seals with this thing?" Cheng Wulin took the test tube from Wang Luli's hand and looked at it.

"No," Wang Luli shook his head and pointed to the plug of the test tube, "In order to activate the explosion, the plug must be injected into the daylight condensed by the user itself, and secondly, you look at the layering inside the tube, each layer of thin liquid needs to be dayless separately to stabilize, so this game should not be mass-produced, so you can only make one or two self-defenses......"

"That's awesome!" Old man Kou interjected, "You little guy has only been in the mirror for a few days, and if you have studied this kind of thing, your future attainments will definitely not be shallow!" ”

"Where is there ...... If it weren't for those comments you made, the kid wouldn't have ......"

Cheng Wulin silently watched the two start to blow each other in business. Anyway, he didn't understand a word about the daylight principle mechanism that the two of them talked about, he only knew that Wang Luli was awesome, and he was indeed awesome.

He looked at the palm of his hand, and the place where he had just pulled Wang Luli's hand seemed to have the residual warmth of the other party. He felt very nervous because he was holding his buddy's hand, and this feeling made him feel very weird.

"By the way, what are you doing with me this time?" Cheng Wulin came back to his senses and heard Old Man Kou ask.

"It's just a little thing to bother you, but I'm actually embarrassed......"

"What's so embarrassing to be embarrassed, my old man is bored here!" Old man Kou touched the top of his smooth head, "My granddaughter Xiaozhi was also taken away by Kou Hongjiao, and I don't want to die......"

He jumped as if he had suddenly remembered something.

"Have you not eaten? Hungry or not? I'm going to get you something to eat! ”

"No need to ......" Cheng Wulin said in a panic, he was not very good at dealing with this kind of kindness expressed by his elders.

"It's okay, it's okay! I'll do it! Old man Kou ran into the next room, "What do you want to eat?" Older dishes or new ones of our time? Before they could answer, Old Man Kou had already rushed into the kitchen.

Cheng Wulin didn't know what to say, Wang Luli smiled: "When you get older, you will become so kind when you see children coming." Then he threw up his head and shouted, "Anything, we all love to eat!" ”

After a while, Old Man Kou walked out with a pot of stew on gloves and a smile.

Wang Luli took the initiative to stand up and took the soup bowl and a long spoon for the three of them to share.

"This ...... What is it......" Cheng Wulin picked up the spoon and stirred the bubbling soup in front of him, feeling the fish bones and boiled green leaves tumbling from the bottom of the bowl.

"I'm afraid that you won't be used to eating the things of our time, so I made your dishes according to the recipe. Try the hawthorn fish stew I made. ”

What is this misunderstanding of the cuisine of our time...... Cheng Wulin sneered. Under the expectant gaze of Old Man Kou, he still politely scooped it up.

This bite almost choked him to death, and the strange fishy smell filled his mouth. He was still a little expecting that Old Man Kou would put something strange and turn decay into magic. He silently prayed that he wouldn't get food poisoning and vomit and diarrhea.

"What did I ask about? Oh yes, what are you looking for me for? Old man Kou scooped a spoonful of soup into his mouth.

"It's still a printer." Wang Luli took two sips without changing his face in Cheng Wulin's surprised gaze, "I thought about a lot of questions about the seals last time I went back, and after that, I also saw some of the uniqueness of the seals during the trip to the Upper Realm Mirror. I'm curious about these ......"

"Why are the seals I see in very primitive forms? Tattoos, flasks, vessels and whips. The technology of the future must be more developed than the technology of history, why do the inkers I see are condensed with the most primitive base, is it a coincidence or? Wang Luli asked with the spoon hanging over his mouth.

"It's no coincidence that the choice of printer substrate is as simple as possible. Although our time is not far from yours, weapons technology has also advanced to a state where people can be killed without the smoke of gunpowder. ”

"But in the mirror it's different. It is well established that daylight has a limit, and printers are no exception. There are two aspects to this limit, one is the limitation of the day itself, and the other is the restriction of the spirit from the base. ”

Old man Kou paused, swallowed the stew in the bowl in one bite, Wang Luli quickly stood up and filled him with a big spoonful, he continued: "The former is a good explanation, that is, daylight cannot infinitely increase the ability of a base item, a daylight knife can be sharper than an ordinary knife, but it will definitely not have the effect of piercing the world. The second is the problem you mentioned, the more complex the object, the stronger the spirit, that is, the finer the object, the less difficult it is to make a stamper. Hiccup......"

He hiccuped and continued, "So even the common ordinary firearms of your time are rarely used to make seals, because not only does it take more powerful mental power and daytime control levels to make it reach the level of seals, but in terms of attack strength, it may not be as good as a bow and arrow marker or something. ”

"I see." When Cheng Wulin looked confused, Wang Luli showed a look of sudden realization, "Then the few problems I struggled with will be solved." ”

"What do you mean that you can only make a printer from ordinary things?" Cheng Wulin looked at the other two, "Then what kind of seal is suitable for me?" ”

"Little Brother Wulin, haven't you already gotten your own seal?" Old man Kou squinted his eyes and stared at Cheng Wulin and smiled.

Cheng Wulin frowned and wondered, "When did I have a seal?" How I don't know. ”

"If you don't believe it, stretch out your hand, and I'll take a look at it for you."

Cheng Wulin stretched out his hand in disbelief, only to see the old man Kou put down the soup bowl in his right hand, his fingers were clenched, a yellow light flashed, and his old dagger seal abandoned star appeared in the palm of his hand.

He stood up, grabbed the abandoned star, and quickly slashed at Cheng Wulin's neck.

Cheng Wulin was startled, and almost didn't throw the soup bowl in his hand. Before I could react, I heard a "bell" in my neck.

"Well, that's not it." Old man Kou smiled and waved his hand to put away the abandoned star, and raised his soup bowl again.

Cheng Wulin could see a small light cluster floating there on his neck with the peripheral vision of his eyes, and cautiously reached out and touched it. This thing was still slightly warm when he grabbed it in his hand, but it was not hot, and it felt a little smooth and warm to the touch.

The light dissipated, and Cheng Wulin's lost meal card was lying quietly in the palm of his hand.
