Heavenly Dao Formula

On the other side, Xia Fan also got the first batch of insect-catching fruits sent by Yinxing Shuzhou.

The pick-up location is in the compound of the New Machinery Engineering Bureau.

After a simple inspection of the goods, the elves of Silver Star got their payment for the goods - a large basket of silver and a dozen boxes of copper coins. Maybe they didn't care about these extraneous things before, but now, these money will become the foundation on which they rely.

The Bureau can directly provide moderately priced food, cloth, coarse salt and iron tools, which are what Shuzhou urgently needs. After the islanders were taken away by the receptionist, Zhuo Fulan volunteered to stay and instruct the Bureau of Mechanical Engineering how to use the fruits.

She has already decided to integrate into the new world as a role model for everyone.

What they saw and heard on the Silver Star Tree Boat, as well as Jinxia's risky and close combat with the imperial fleet, just to save more tribesmen, all show that they are completely different from the imperial people.

This trust is worth her paying.

After completing the preparations, Zhuo Fulan first scraped off the beards on the outer shell of the insecticide with a scraper, then drilled a small hole in the exposed shell, and poured the milky white liquid inside into a porcelain bowl.

These liquids look quite viscous, much thicker than coconut milk.

"The juice of the insect trap fruit will be affected by the light and become invalid, so it must be used as soon as possible after being poured out." She introduced while operating, "In the case of standing still, its effective time is between one hour and ten hours. The stickiness is stronger after that. Of course, if you just catch insects, counting breath time is enough."

"So you use sunlight to control the viscosity?" Mo Yun immediately sensed the key.

"To be precise, any light is fine." Zhuo Fulan applied the slime to the ends of the two sticks, then put them together and put them in a black box, "therefore, the hole must be sealed for unused insect traps. Put it in a dark place."

After only waiting for half a quarter of an hour, she took out the wooden stick and handed it to Xia Fan.

"You can try to pull it apart, being careful not to touch the juice, it hasn't started to solidify yet."

After being translated by Mo Yun, Xia Fan followed his advice.

He tugged lightly first, but the stick didn't move at all.

So he began to increase his strength.

The two ends of the stick were gradually pulled apart, but it was still possible to see countless filaments connected at the bonding place.

It wasn't until almost 50% of the strength was used that the stick was completely split in two.

This adhesive strength was really beyond Xia Fan's expectation.

Mo Yun took the exhibit curiously, and looked around, "What will happen if someone touches it?"

"It will stick, and it is quite troublesome to deal with." Zhuo Fulan replied, "It is especially suitable for bonding living things, wood, porcelain and fur, and metal and crystal are not so effective. When blocking imperial invasion, The islanders have tried using it as a weapon and as a trap, but the results have been mediocre."

Xia Fan could imagine it.

In order to maintain its stickiness, it must be stored in the dark, so it must be taken out before the battle. At the same time, it will quickly fail due to light, so only in caves, underground and other places have a little chance to survive until it solidifies. As a weapon, the limitations are too big.

However, as a kind of biological glue, it can be said to be quite qualified.

"Miss Mo, what do you think?" He looked at the person in charge of the Mechanism Bureau.

"I have to admit that you are very discerning in picking things." Mo Yun said comfortingly, "There are golden vines in the front and insect traps in the back. Although it is a pity that you can't stick to metal, the specific adhesion needs to be further tested, but the machine There should be quite a lot of places to use it.”

"Then let the Silver Star Tree Boat increase the production of insect traps." Xia Fan turned to Zhuo Fulan, "What will the glue look like when it fails?"

"Similar to a solid, with a certain hardness, but not as hard as a stone." The latter took out a "white stone" from his pocket and put it in Xia Fan's hand.

Xia Fan pinched it and found that it was smooth, like pebbles that are common by the river, but if you use force, you can feel that it has a certain degree of toughness. Considering that this colloid can be shaped freely, can the finished product be used as some components that do not require high strength?

After he asked what was in his heart, Zhuo Fulan did not deny it immediately, but replied with a little regret, "I also asked my father about this. In fact, the islanders also want to use it to lose its stickiness after solidification. Real objects such as short bows and knife handles were made, but in the end only jewelry was successful.”

"Why?"

"If the glue is piled up too high or too thick, there will be a situation where the glue on the surface solidifies first, but the inside has not yet. It has poor light transmission, so the outer layer will become a kind of airtight container, preventing Complete consolidation of the glue."

"So that's how it is." Mo Yun said thoughtfully, "This is equivalent to the fact that the object has only a thin shell, and the inside is empty, so it is difficult to maintain its own strength. It is okay to make jewelry, but if it is a bow or something It is easy to break in use."

"It's okay if it's just damaged." Zhuo Fulan smiled wryly. "The key is that the glue inside will still leak out. If you are not careful, it will cause disasters, such as sticking clothes and flesh together. I want to tear it off later." , almost no less than a torture."

Can't light... go in?

Xia Fan was lost in thought.

"What new ideas do you have?" Mo Yun asked with ease. The two had worked together for a long time, and she knew that the problem had already been figured out as soon as she saw Xia Fan's appearance.

"It's hard to say for the time being." Xia Fan organized his words, "You should still remember that there are actually many kinds of light, right?"

"Are you talking about the content written in the principle of Gewu?" Mo Yun nodded, "Although it is difficult to understand, I still remember those words - what our naked eyes can see is only visible light, and there are many other things besides visible light. The invisible light... To be honest, it’s incredible, even though it’s no longer visible, you can still know it exists.”

"Isn't Qi such a thing? You can't see it, but you can drive it." Xia Fan spread his hands, "Of course that's not the point. What I want to say is that different types of light have different penetrating powers."

"Uh...Master Xia, Miss Mo, may I ask, what are you discussing?" Zhuo Fulan asked curiously.

Mo Yun repeated Xia Fan's words on the spot.

The elf girl suddenly fell into a daze.

"You can continue." She turned to Xia Fan again, "If I understand correctly, you want to try those invisible lights with stronger penetrating power to solidify the inside of the colloid?"

"That's the way of thinking."

"Interesting." Mo Yun has already entered the state of research, and there seems to be light flickering in his eyes, "If the experiment is successful, it can also prove what we heard in disguise—there are invisible lights in the world. How do you plan to make them? ?”

"Originally this was a very difficult thing to do, but just during the time I was visiting Gyeonggi, I stole... from the Privy Council and picked up a book of secret records of immortal arts."

"You mean - fairy art?"

"Well, the technique is called Jiuyouhuo."

Mo Yun's cold and indifferent expression has completely disappeared, replaced by an eager expression.

Xia Fan couldn't help laughing, "I can show it to you for reference, but to be honest...it's not easy to understand."

Suddenly he felt a flash in front of his eyes.

Mo Yun grabbed his arm first, and then hugged him tightly.
