"Master Liu is still satisfied with this lining?"

Master Jiubao glanced at the new clothes on Liu Zhengyang, and naturally judged that it was the new material they had developed.

Liu Zhengyang had already felt a bit when he was testing the city defense system.

The inner lining is very silky, and there is no sense of restraint, but it is also a very good baby.

"very nice!"

Liu Zhengyang's appreciation made Master Jiubao laugh.

"Liu, please come with me!"

Master Jiubao took Liu Zhengyang through the refining room scorched by the heat.

But then I arrived at a place where the temperature was slightly lower.

"The raw material for this lining is here!"

After speaking, Master Jiubao opened the warehouse door in front of him.

Then a chill came over.

There are many people in winter clothes working in it.

"These are a unique silkworm we discovered recently. According to the naming rules in Haiyan City, we call him Tianhan Silkworm!"

Liu Zhengyang laughed.

His satisfaction was not only because of the rapid progress of Tiangongfang, but also because of Master Jiubao's respect for Haiyan City.

If you don't respect it, there will be no separate explanation based on Haiyan City's naming qualifications.

This shows that the cooperation between the two parties is now very harmonious.

Finally, there was what a family should have looked like.

It's just that this is just the beginning.

Liu Zhengyang listened to his narration, and then followed him to the edge of the shelf.

Within each tray, a plump white sky cold silkworm was lying on the emerald green mulberry leaves.

The only unique thing about these cold silkworms is that there is an ice-blue cast-like bulge on their heads, which at first glance looks like a gemstone inlaid on their foreheads.

"This is……"

"This is the demon core of Tianhan Silkworm!"

Master Nine Treasures responded with a smile.

"Demon core?"

Master Jiubao nodded: "Yes! It's the demon core!"

Liu Zhengyang turned around and glanced at Master Jiubao: "In other words, all the Celestial Cold Silkworms raised here are monsters?"

"Correctly speaking, it is a kind of artificial monster race!"

Master Jiubao said with some emotion: "I have to say, technology is really amazing! When Haiyan City provided us with these cold silkworms, we old guys were shocked!"

Let alone them, Liu Zhengyang was shocked.

what happened?

Have all the demons cultivated? It seems that the potential of Haiyan City is much stronger than what I imagined!

"How is the productivity of cold silkworms these days?"

Liu Zhengyang glanced at the wide warehouse and asked.

"These days, cold silkworms are very edible, so basically every shelf needs a dedicated manpower to take care of, but fortunately, their growth period is very short, it only takes more than ten days!"

"After that, they will condense the Tianhan Silk we need!"

After speaking, Master Jiubao took Liu Zhengyang towards the inside.

Soon I saw ice-blue silkworm cocoons, soaking in the pool, and there were apprentices beside them who were peeling the cocoons.

This process is a very patient process.

People who are impatient can't do this kind of thing.

Liu Zhengyang frowned.

"Jiubao, these workers are all apprentices from our Heaven Workshop?"

Liu Zhengyang's question made Master Jiubao stunned for a moment, thinking that he was worried about safety and confidentiality. He patted his chest and promised: "Yes! And these people are absolutely safe and reliable!"
