Plans and Material Preparation

Seeing how intently Lu Yuan was looking at the shell, Gregory also stepped closer and pointed to it, explaining, "This is a special metal developed by our family. It has extremely high plasticity and toughness, and when it explodes, the outer shell will fly out along with it, making it an effective missile in itself."

Lu Yuan nodded upon hearing this. No wonder this thing was only the size of a fist, yet Gregory could confidently claim it could injure Fourth Order opponent. Just the fragments scattered after the outer shell exploded would be enough to give someone a hard time.

Gregory spread the Parchment Scroll depicting the seven-layered structure, along with the drawing containing Heretic Inscription, on the table, and looked expectantly at Lu Yuan, waiting for him to give him a good idea.

Lu Yuan knew exactly what Gregory wanted; there were only two things.

First, the core of the third-layer explosion is not stable enough, requiring a dedicated detonator, and its storage structure also seems unreasonable.

Secondly, the hope is to add a search Inscription to the third layer, which can actively detect fast-moving humans and actively search for signs of life.

Of these, the feasibility of the automatic Person-Finding Inscription is Gregory's most important and most needed thing.

Lu Yuan studied the drawing with the Heretic Inscription for a while and then understood the situation. The original effect of the Inscription was to attract people to walk into Inscription unconsciously. Turning it into actively seeking people was not a big problem for him. With his current strength, he could easily solve it.

But as soon as he put down the blueprints and looked at the seven-layered Parchment Scroll again, his brows furrowed little by little.

The reason is very simple: just because the Inscription itself can do this doesn't mean it will work when placed inside the bomb. After all, it has a multi-layered structure, and it's very difficult for the Inscription to be activated through the multi-layered structure. Moreover, the stability of the Inscription after the first two explosions must be guaranteed.

Furthermore, what problems would arise if this Inscription were placed in the third inner ring?

First, will mass production be too difficult? Lu Yuan needs to figure this out first.

Secondly, Holy Water and Contamination need to be added to the core layer. After adding these, will the Inscription wear out, become damaged, or be rejected? Will the Inscription still be able to carry anything? After all, no one knows how much force or weight its tracking can carry.

Finally, does tracking require a constant supply of energy or sanity? Otherwise, how will it keep chasing? It can't just keep chasing endlessly by injecting a little sanity, can it? That's unrealistic. So, how far can its tracking distance be guaranteed? Lu Yuan needs to figure all these questions out.

So this time, for Lu Yuan's Dragon Blood Potion, Oden put in all his effort, coming up with ideas for him one after another in Lu Yuan's mind.

The two discussed whether the Inscription would be destroyed by the explosion. This was actually easy to solve; as long as the materials were reinforced to a certain extent, there shouldn't be much of a problem.

Secondly, reverse deduction is actually the simplest for Lu Yuan. As long as the Inscription given by Gregory is correct, it is relatively easy for Oden and Lu Yuan to deduce it together.

However, mass production is a different story. Preliminary assessments indicate that it is extremely difficult. Even if Lu Yuan helps to reverse-engineer the Inscription and hand it over to Gregory, all Lu Yuan can do is try to reduce the difficulty to some extent. But for mass production, it still depends on Gregory himself. Lu Yuan really can't help much in this regard.

As for whether adding liquid to the core layer will cause the reverse-pushing Inscription to be unable to move due to excessive weight, there is no solution for the time being, because the Inscription have not yet been reverse-pushed out, and Lu Yuan does not know what its effect is.

Finally, there's the issue of a continuous supply of energy. After a moment's thought, Lu Yuan realized there were only two things he could do: first, limit the tracking range; second, consume more rationality when injecting it. That would solve the problem.

The remaining issue is the third layer detonation problem in Gregory. It's not easy to activate, and its strength and structure are not good enough. The only solution is to change the materials, or simply use Inscription instead, and optimize the sensitivity of the third layer activation device to sanity.

As for the structure of the storage space, Lu Yuan couldn't give an answer either, and the strength and activation seemed to be the only solutions that could be achieved through Inscription.

But as Lu Yuan thought about it, two ideas popped into his mind. The first idea was that if the detonator was placed on the second layer, giving the second layer a certain detonation capability, once the second layer was activated, it would automatically activate the third layer as well. In this way, there would be no need to deliberately tamper with the third layer.

However, this would require changes to the structure between the second and third layers, and the stability might be significantly weakened, since Gregory's idea was to turn it into something similar to Booby Trap.

The second idea was to have the Inscription only sense human presence and fast-moving objects, changing the original autonomous search for people to sensing human presence, which would be much simpler in comparison.

In this way, after the second layer explodes and someone is blown up, the third layer will not actively seek out the person. It will remain at the location where the second layer was knocked away after the explosion, and will automatically detonate whenever someone passes by. However, doing so deviates somewhat from Gregory's original idea.

Lu Yuan considered it in his mind and decided to let Gregory make the decision himself, so he shared his two ideas with him.

As Gregory listened, his eyes suddenly lit up, and he slammed his hand on the table.

"Excellent!" Gregory's speech quickened suddenly. "If that's the case, we won't even need to search for anyone. After the second layer explodes, the third layer will be blasted away like a rock, landing where it lands. As long as someone passes by, it will automatically detonate. Scattering a patch along the enemy's path will create a no-go zone. Anyone who comes will be bombed, and it will be extremely difficult to clear."

"But that's not right. What if it's an animal? Like a hunting dog, or some kind of supernatural being attacking the city? So we need to be able to distinguish them."

As Gregory spoke, he pulled out his notebook, buried himself in it, and quickly jotted down the plan.

Lu Yuan waited until he finished writing before explaining himself.

"Regarding this part, since the Inscription haven't been deduced yet, I can't give you an answer at the moment as to whether what you're asking about targets humans or the supernatural. I can indeed deduce the Inscription, but I can't give you answers about the others at the moment."

Lu Yuan paused, then offered another solution. "There's another method, which is to use the second layer to detonate the third layer, but the structure of your other layers will need to be modified accordingly."

After listening, Gregory stared at the Parchment Scroll for a while, then said that he needed to consider it for the time being, since it was completely unrelated to his plan, so he really needed to think about it.

So the two of them discussed the Parchment Scroll for quite a while, from the detonation of the second layer all the way to how to sense the landing of the third layer. Finally, Gregory closed the notebook, his face full of undisguised satisfaction.

Before Lu Yuan could even mention the materials, Gregory proactively stated, "The materials will be delivered to the Research Room shortly; you can just come and pick them up then."

Lu Yuan thanked him and also made it clear upfront, "I'll come here later to reverse-engineer the Inscription I have time. Once that's done, I'll help you revise the plan, and then our deal will be complete."

"No problem," Gregory agreed readily. "If you make any new discoveries during the trip, I'll pay you extra."

Lu Yuan also said there was no problem.

After giving his instructions, Lu Yuan relaxed completely. It was at this moment that he suddenly remembered something.

Oh no, Frey hasn't been told anything yet.

He had originally planned to go see Frey in the morning, since the materials for the second plan should have arrived by then, and he had promised to take her with him yesterday. However, he went to the Bounty District in the morning, and then followed Gregory into his Research Room at noon, completely forgetting about the matter.

So Lu Yuan quickly gave Gregory a few brief instructions and then walked out.
