The evolution of Zerg

When it comes to tension and toughness, Daoyan is a bit confused.

In weapon refining, there is a mineral that can improve the flexibility of weapons, but the output is very small, so the price is very expensive.

Daoyan calculated in his mind for a while and shook his head: "The cost is a bit high."

The Heavenly Master asked: "Is there really nothing we can do?"

Daoyan thought for a while and shook his head.

Liu Chuanzhi on the side said: "Why do you have to use spiritual materials? Can't ordinary materials be used? You made this film just to cover the spiritual energy. What is missing now is tension."

Daoyan's eyes lit up and he said: "Yes! I got into a dead end! But, what kind of ordinary materials can increase tension?"

Liu Chuanzhi said: "As everyone knows, I am a doctor and have done some research on medicinal materials."

The Heavenly Master interrupted from the side: "Wait a minute, weren't you once an emperor? Why did you become a doctor?"

Liu Chuanzhi rolled his eyes: "I've been abdicated for several hundred years, so I can't be self-taught!"

The old Tianshi still wanted to make a point, but Dao Yan said dissatisfiedly: "Stop saying a few words! We are thinking about the problem now, don't talk about useless things, Lao Liu, please continue."

Liu Chuanzhi nodded: "There is a kind of wood in our Qingfeng Empire that is specially used to make wine barrels. Its fruits can also be eaten in times of famine."

The old Heavenly Master interrupted from the side: "What's the use of all this? Get rid of these useless things."

Dao Yan looked at the old master again, with murderous intent in his eyes.

Liu Chuanzhi ignored the old master and continued: "This kind of wood is called oak, and it has strong sealing properties."

Dao Yan said: "Are you talking about its tree pulp or its own material?"

Liu Chuanzhi said: "It is tree pulp. I have done some experiments. After the oak pulp is dried for a certain period of time, it has strong toughness and strong stickiness. Maybe you can try this."

Dao Yan nodded: "So, where can I buy this kind of wood?"

"Ha." Liu Chuanzhi said with a smile, "You are so lucky, I just have it in my pocket."

After speaking, Liu Chuanzhi took out an oak log from his mustard bag.

Dao Yan took the wood and made a cut on it, and translucent glue flowed out of it.

Daoyan dipped his hand into it and found that it was indeed very sticky and could bring out a long string of silk.

He put the oak pulp in his mouth and sipped it, and then said twice, "It's bitter, but it's not a big problem."

Liu Chuanzhi said: "How about Dao Yan? Okay."

Dao Yan was not sure and said, "I'll give it a try."

Then, the oak was turned on again, and this time he didn't put the materials into the furnace all at once like before.

This is a new field, a new way of mixing ordinary materials with spiritual materials.

Dao Yan was refining the weapon carefully, and he said: "I can't guarantee that it will be successful the first time. Lao Liu, if you still have extra wood, take it all out and let us blame the weapon refining sect."

Liu Chuanzhi waved his hand and said, "Hey, they are all worthless gadgets. If you want, I can give them to you."

Dao Yan turned his head, glanced at Liu Chuanzhi and said, "You are such a good person."

After saying that, he concentrated on refining the weapon again.

With master-level experience, Daoyan acted quickly, and soon a new film was produced.

Dao Yan wiped the sweat from his head and said: "Huh, luckily this oak is strong enough, otherwise I would have almost failed. Don't be stunned, give it a try and see how it goes."

The Heavenly Master took the film and pulled it slightly. The whole film suddenly became tight, but it did not break.

Dao Yan said anxiously: "Be gentle! Be gentle! You're using too much force! The membrane will rupture later!"

The Heavenly Master said with satisfaction: "No, it's just right! I'm very satisfied."

Dao Yan said: "Then what's next for practice?"

Both Lao Tianshi and Liu Chuanzhi agreed.

As long as a cultivator can make such things as spiritual vegetables, sometimes the elixirs are too expensive, so they will buy some spiritual vegetables for cooking.

Soon, three spiritual dishes were placed in front of Dao Yan.

The first portion is meat spiritual vegetables, the spiritual energy dissipates the fastest.

Dao Yan cut a piece of film open twice, carefully covered the spiritual meat dish, and then placed the excess edge under the plate.

The same goes for spiritual vegetables and spiritual soups.

After completing these tasks, Dao Yanbian and Lao Tianshi waited.

Before being covered, these spiritual vegetables will emit an attractive smell.

However, after covering it with a film, the smell became very weak and disappeared after a while.

After waiting for half an hour, Dao Yan said excitedly: "We succeeded!"

The Heavenly Master also grinned, and the fragrance of the creation nectar could finally cover him up.

Liu Chuanzhi said: "Dao Yan, give me a name."

Dao Yan thought for a long time and said, "How about we call him the rubber membrane?"

The old master said: "This name is really hard to pronounce."

Daoyan spread his hands and said, "How about you come?"

The Heavenly Master thought for a while and said, "This thing is used to seal spiritual energy. How about calling it a spiritual sealing membrane?"

Dao Yan nodded and said, "It's interesting."

Liu Chuanzhi said: "The name is too fancy. I don't think it is necessary to be so exaggerated. They are all made of ordinary materials. I think it would be better to call it plastic wrap."

Daoyan's eyes lit up again: "That's right! Keep it fresh! Keep it fresh! Keep the freshness of the spirit energy! Lao Liu, you are really a talent!"

In this way, the name of the plastic wrap quilt was decided.

As a simple technique, Dao Yan did not hide it. After a little programming, he taught this technique to his disciples.

As a result, the Lianqi Sect's plastic wrap began to be sold in major spiritual food restaurants.

It is most obvious in the conquest army.

The monks who fought on the front lines unleashed unparalleled fighting power in order to eat the freshest food.

The scavenging locusts were beaten back steadily.

The monks also discovered another use for plastic wrap.

That is, dead scavenging locusts can be wrapped to prevent them from being eaten by their own kind.

The plastic wrap has done a wonderful job, and all the monks in the alliance have high praise for the Weapon Refining Sect.

Even the weapons and equipment were sold in large quantities.

Not forgetting the well digger, Dao Yan gave three parts of the profit from selling the plastic wrap to Lao Tianshi and Liu Chuanzhi.

The Heavenly Master was very happy. After spending so much effort, he finally finished the film. He accidentally made a fortune and made a lot of money.

"Well, put the money in Tianyimen and let the disciples and grandchildren practice well." The old Tianshi thought with satisfaction.

Then, he covered the jade bottle of good luck with the cut plastic wrap.

After ensuring that it was tasteless, the Heavenly Master stared at the jade bottle of good fortune nectar and felt a little worried.

Isn't it unnecessary to open the plastic wrap for this and fine wine?

"I'm such a fool!" The old master looked up to the sky and sighed.
