"Good tea!" After taking a gentle sip of the tea soup that had been poured into the Kiln Transformation Tianmu Jar with a silver mouth, Liang En exhaled lightly and nodded in satisfaction.

Compared with the brewed tea I drank before, this kind of tea has reduced the bitterness because it has been pressed and kneaded, highlighting the sweetness of the tea and the thickness of the foam, and it has a soft and sweet taste.

Truth be told, he prefers this taste, but unfortunately, tea cakes have been eliminated historically because of the cost, so much so that he has never tasted this ancient taste before this.

With tea, the two of them were talking and laughing, and they quickly ate those snacks and then chatted again, as for the content of the chat, there was everything in the world - one moment was everyone's own observations, and the other was about alchemy.

"Look at my recent new invention, which I made after seeing your lamp god, and I hope to be able to do some reconnaissance-like work for me like your lamp god."

When it came to the key point of alchemy, Ao Lei took out a small bird made of wood from her bosom, and after gently pressing it twice, the little bird quickly flew up and let out a pleasant chirp.

"Very good." After taking a closer look at the birdie, Liang En gave a very positive assessment. This is not just a compliment, but a conclusion made after seriously feeling the bird's situation.

Because the trap bird in front of him is only the size of a palm, it can fly flexibly, and even by quickly vibrating its wings, this wooden bird can flap its wings and hover in the air in a way that the prototype can't do.

In addition, this bird is also capable of making various movements or making chirping sounds like a normal bird, and if it were not for its rough appearance, Liang En would even think that this bird is real.

"I have to say that your design on this little thing is still very ingenious, and there are many things that make people shine, but after listening to your design ideas, I want to know one thing, and that is how much does your bird cost?"

After getting Ao Lei's permission, Liang En carefully dismantled the trap bird with curiosity and examined it with the alchemy method he mastered, then turned his head and asked.

"One hundred...... a hundred and seventy taels of silver." After squinting her eyes and thinking for a few seconds, Ao Lei gave an answer. "If it is made on a large scale, it should be able to drop to about one hundred and twenty taels of silver."

"But if you change a lot of the raw materials in it to secondary raw materials, the cost will become at least 1/3 of the original." Liang En said, pointing to some of the spare parts inside.

"For example, this gold-inlaid silver magic array plate can be completely turned into a copper plate inlaid with silver, and the wiring inside can also be cut by at least half, so that the cost of this part alone can be reduced to 1/5 of the original." ap.

"But if that's the case, there will be some problems with the way the bird flies, and it will appear that the flight path is too rigid, and it will be easier for people to spot." Ao Lei obviously didn't understand Liang En's statement.

"You're right, but the problem is that you said earlier that this bird is mainly for reconnaissance around you, which means that they are likely to be a consumable, and the cost of consumables is too high."

"What's more, you said before that these birds are used for reconnaissance, so the use environment is either this kind of large-scale reconnaissance in the wild, or it is to expand the detection circle in an emergency, and these do not require a high degree of simulation of birds."

"Because in the former case, your trap bird is easy to conceal even if it's not so real. In the latter case, no matter how real your bird is, it will be easy to spot."

"So in my opinion, it is enough to keep these things to a minimum in terms of quality, and the lack of quality can be compensated for by sufficient quantity."

Perhaps because he lived in an industrial society, Liang En's view of many items has always been to pursue cost-effectiveness, and do not require permanent use. So he'll take that idea into his craft of otherworldly items.

Therefore, for some items that are destined to be consumables, Liang En will cut the cost of those things as much as possible, in cost

At the bare minimum, these things can meet the design goals.

"You have a point." After listening to Liang En's words, Ao Lei nodded, her goal in making these birds is to build a scouting circle around herself, and she needs many birds, so it is indeed a necessary thing to reduce costs.

After all, it's not a child, there aren't so many resources for her to use on this icy desert island, and some things should be changed.

"But honestly, I'm really not very good at this kind of thinking, and I'll need your help in the future." Thinking of this, Ao Lei stood up very seriously and bowed to Liang En.

"Don't dare, don't dare, I can only say that we learn from each other." Liang En was a little hurried to signal Ao Lei to get up, and when the two of them got up at the same time to face each other, the two of them suddenly laughed at the same time.

With such a smile, the original estrangement between the two sides has disappeared a lot, and the communication after that has become significantly easier, instead of being polite as before, but full of a faint sense of alienation.

However, just as the two of them discussed the difference between alchemy and alchemy, and then discussed the difference in extraordinary power in different backgrounds, a sudden explosion erupted in the forest a few kilometers away.

At first, they thought it was a volcanic eruption, after all, the place was very volcanic, and the dull explosion sounded close to the sound of a volcanic eruption.

But they soon realized that something was wrong, because their sensitive perception did not perceive the vibrations of the ground as is common with volcanic eruptions, nor did they see the columns of smoke that would normally occur.

What's more, the sound grew closer, as if a heavy train was rushing towards their location.

"What's the situation?" After eyeing up at Ao Lei, Liang En and her stood up at the same time, and then loaded their things and armed themselves as quickly as they could.

It was also at this time that Liang En discovered that Ao Lei's armor was not worn like a normal person, but a phantom of a set of armor appeared and quickly turned into a real "grow".

"These are my scales." Ao Lei, who read his thoughts from Liang En's eyes, quickly explained, and then flew towards the place where the sound came from with Liang En,

A few minutes later, they flew to the place where the sound came from and looked down, and the next second a huge thing caught their eyes -

It was a giant earthworm hundreds of meters long and as thick as a train car, and it was now moving rapidly in the shallow depths of the earth's surface, where the soil parted like ocean waves, and both stones and tall trees were shattered by its easy movement.

"Monsters? I'm in trouble."

After seeing the monster's true body, Liang En immediately remembered the large monster disguised as a palace castle he had encountered in Malacca before, and at the same time his head buzzed, after all, the psychological shadow that the monster gave him last time was too big.
