The difficulty in making the device this time lies in how to sew the two together.

The tortoise shell provides energy, and the dragon scales are responsible for output, both are indispensable. But the problem is how to link the two together, and there can't be any problems at all, after all, this thing is used to survive the heavenly tribulation.

Luo Yan thought patiently for a long time and decided to just make a two-way mirror.

Dig a hole of the right size on the back of the black tortoise shell, then inlay the dragon scales into it, and finally combine the runes of the two together again...

Can this also be combined?

Using the scanning function to confirm the internal structure of the two arrays again, it can be found that they are almost completely different. To combine the two seamlessly is like embedding a mobile phone in a computer, and then operating the mobile phone on the computer to make a call... It is not impossible, but it is definitely not that simple.

He was thinking hard while writing and drawing on the paper. Shi Liuli sat beside him and watched quietly. Suddenly he asked:

"Since we are going to combine the two into one, why not add a middleware?"

The so-called middleware is a structure similar to an "adapter plug", which is generally used to connect two different magic weapons. It is a relatively niche method in casting.

Why is it so niche? Because the magic weapon that was finally made is too ugly, just like the monster in Yunmengze Country before, it doesn’t look like a dragon, and it doesn’t look like a turtle, which makes people want to vomit when they see it.

Even if such a magic weapon meets the customer's requirements, it would still be a disgrace to the weapon maker...

Um?

Luo Yan suddenly realized a problem, that is, these two magic weapons originally came from the Xuanwu statue.

Could it be that the Xuanwu statue itself was originally a middleware to connect the Xuanwu armor plates and the dragon scales?

Thinking of this, Luo Yan finally understood.

If middleware is used for connection, the final product will inevitably be bulky and black, not much smaller than the original Xuanwu statue.

Whether it is a flying sword, a mirror, a seal... most of the magic weapons must be light enough, otherwise they will fly very slowly and fail to hit people, not to mention their effectiveness.

But there is a kind of magic weapon that does not need to be moved once it is deployed.

Ding vessel.

What if we can make the dragon scales and basalt armor pieces into the corresponding formation tripod? Anyway, the heavenly tribulation will not move, so we only need to put the tripod on the ground, and it will not be a problem no matter how heavy it is.

Giving up the original idea of ​​making it into a mirror, Luo Yan immediately opened up the layout completely and decided not to consider various restrictions. The functions must be complete and the effects must be powerful. Of course, the most important thing is that it must be hard enough to not be broken by the heavenly calamity.

Luo Yan was working attentively, writing, drawing, and scribbling. Shi Liuli beside him looked at him and thought, what her husband is drawing is... a fortress?

What's wrong? Do you want to completely transform Tiangongfang?

No, judging from my husband's design, the defensive counterattack feature is almost obvious. Tiangongfang is inside Penglai Yuqing Temple, so there is no need to add so many defensive designs separately, and these things are obviously not something that can be brought with you, so what is the situation that requires the construction of such an inconvenient fortress to be moved?

A flash of inspiration came into Shi Liuli's mind.

Overcoming the tribulation...

Husband, have you started making plans to overcome the tribulation?

This was still not right. He was so lazy that he wouldn't even do the work for the Tiangong Workshop, so how could he prepare for the heavenly calamity that hadn't come yet?

Unless he is planning to survive the tribulation soon!

After a series of conjectures and reasonings, Shi Liuli felt that he was very close to the truth, but suddenly felt a little lost and uneasy.

So, my husband will soon become a Nascent Soul cultivator?

Well, since he didn't want to mention this to me, I guess he was afraid that I would worry and be anxious.

I also need to improve my skills as quickly as possible and not hold my husband back.

Thinking that Tiangong Workshop would finally have a Nascent Soul cultivator, Shi Liuli felt quite excited. He simply postponed as much work as possible for the next few months and planned to concentrate on improving his cultivation progress.

Of course, it is a pipe dream to want to upgrade quickly by practicing step by step and with great patience. The only right way is to find a secret place, look for adventures, and try your luck.

…

Luo Yan spent several days working on it and finally came up with a rough outline of the design.

Just as he was about to perfect it, he suddenly heard Junior Sister Shi Qing asking for a meeting outside.

"It's not good, Senior Brother Jingyun!" She shouted outside the door in panic, "The affairs in the workshop are piling up like a mountain, and Third Senior Sister can't handle it all. She's going crazy!"

When Luo Yan heard this, he didn't understand what was going on, so he followed Shi Qing out and came to the back hall of Tiangong Workshop.

Then I found out that Shi Liuli had asked for leave a few days ago for some reason and went out, leaving the affairs of the workshop to Third Senior Sister Liang Ruohua to take over temporarily.

This was what they did in the past, but Shi Liuli usually returned the next day or the third day, but now he has not returned for several days. Liang Ruhua does not understand many matters, so the work has piled up, and she has no choice but to call Luo Yan back to help.

Luo Yan was also a little puzzled after hearing this, wondering where his wife had gone.

Forget it. She is very lucky and has the magic to protect her, so there will probably be no problem.

As for these matters, it seems that I am the only one who can do it.

"What kind of work is there?" He picked up the documents on the table.

"The statistics of business accounts, the handover of sales business, the maintenance of raw material supply, and some daily affairs assigned by the sect." Liang Ruohua pointed to the pile of documents on the table, "That's about it."

Luo Yan: ...

"I'll go get Liuli back." He said helplessly, holding his forehead.

After leaving Yuqing Temple, Luo Yan began to have troubles again.

She left without saying a word, so where should I start looking for her?

"Ajing, where do you think Liuli will go?" Luo Yan subconsciously asked Kunlun Jing.

"I don't know." Kunlun Jing shook his head and said, "But given her personality, it's unlikely that she would leave without saying goodbye. She should leave a message to tell you where she went."

"That's true." Luo Yan thought for a moment, then ran to the gate of Yuqing Temple, found the white jade puppet Nian Nu who was guarding the gate, and asked it, "Did you see Master Dongyou leave Penglai?"

"Master Dongyou left a message for you," Niannu replied, "She went to Ulleung Island to explore the secrets."

"Oh?" Luo Yan asked in surprise, "Why didn't you tell me earlier about such an important matter?"

"Master Dongyou specifically instructed me to do so," Nian Nu continued, "If you ask me about her whereabouts, I will answer you truthfully. If you don't ask, I won't mention it."

Luo Yan was speechless when he heard this, and said after a while:

"Did she arrange it this way when she left before?"

"So far, Master Dongyou has left you messages to let you know his whereabouts thirty-three times before leaving," Nian Nu replied, "and you didn't ask about it thirty-two times."

Luo Yan was silent for a long time and said:

"Don't tell Master Dongyou about this. If she asks... just say I ask her every time."
