Don't mention it, Li Pu has indeed heard of the mechanical summoning array.

It's a type of mechanical summoning array that can 100% summon mechanical summoning beasts.

Moreover, it can also improve the minimum rank of the summoning sigils.

Back then, Senior Sister Wang Nuonuo said that her D-grade Mighty Steel was summoned using a level 1 summoning sigil on the mechanical summoning array.

That level 1 summoning sigil with a "Guaranteed E~D-grade" turned into a "Guaranteed D-grade" with the help of the mechanical summoning array.

As for the mechanical summoning array at Xidu University, that's all he knows.

"Seems like you're quite informed."

"Actually, ours here is pretty similar."

Listening to his introduction, Xiu Lijia started to introduce the situation in the Imperial Capital.

The mechanical summoning array in the Imperial Capital is of even better quality.

While ensuring a 100% summoning of mechanical summoning beasts, if using a "Guaranteed E~D-grade" summoning sigil, it can be improved to "Guaranteed C-grade", preserving the minimum rank and even improving one grade higher than Xidu's.

Li Pu previously calculated that the five attribute slots of a level 5 summoning sigil, if all used to improve the guaranteed rank, can reach up to B-grade.

As such, with the help of the mechanical summoning array here, it can be improved to A-grade.

However, that's the limit of this mechanical summoning array; even a "Guaranteed A-grade" summoning sigil cannot be improved to A+ or S.

Wanting to summon A+ or S directly depends on luck.

In fact, Li Pu didn't find a "Guaranteed A-grade" attribute in the slots he browsed.

Keep in mind, the summoning sigil libraries of the ten academies are interconnected.

He didn't see it in Xidu, so naturally, it's not in the Imperial Capital either.

Of course, some strong attributes come with hidden conditions.

For example, the "Dragon Blood" attribute takes up three slots but inherently has a "Guaranteed C-grade".

After all, a summoning beast with dragon bloodline couldn't be below C-grade.

It's just that such summoning sigils are rare, usually snatched away by whoever discovers them first upon their appearance.

Overall, many students avidly pursue mechanical summoning arrays.

Because with it, it's equivalent to obtaining two extra guaranteed rank attribute slots, isn't that appealing.

Of course, the opportunity to use such a good thing is quite rare.

Wanting it doesn't mean you'll surely get it.

And for students, the only condition to activate the mechanical summoning array is the Mechanical Department points.

"How about this, you earn the Mechanical Department points from the seniors."

"Then I'll help you fill up the rest to 100 points, so you can use the mechanical summoning array once."

That's what Xiu Lijia said.

"Oh? Is that okay."

Li Pu was slightly surprised.

"Why wouldn't it be."

Xiu Lijia smiled.

After all, she only has about 20 points, aside from exchanging some materials in the Mechanical Department, these points aren't of much use.

Accumulate 100 points, that's far off.

Moreover, as a freshman, she can only follow senior sisters and seniors to do projects, thus there's basically no need for such materials.

What's more, during this period in the dungeon, Li Pu saved her several times, especially at the Gagagar Glacial Shark Gobi.

If not for Li Pu, she might still be lying in the infirmary or dormitory.

The most crucial point is that she has the support of Xiu Cangjia, so she's not urgently in need of summoning resources.

Li Pu: I advise you not to see her as too reliable.

"Then thank you."

In response, Li Pu could only express gratitude.

He seemed to have nothing to offer this female classmate.

She doesn't like card games, only likes repairing machines.

He could only wait until he really summons a mechanical beast and offer her more repairs.

But then again, if it's a mechanical summoning beast, will the love punch still have an effect?

Thinking aside, ultimately Li Pu felt the only thing he could do was find a chance to give Xiu Cangjia a few rare cards.

Li Fan: Let me.

"Mechanical summoning beasts, actually, are not bad."

"Feels like they might be cool..."

Thinking about his fourth pact to be made on the mechanical summoning array, he couldn't help but feel a bit excited.

After all, almost every boy has had a mechanical dream.

It's just that now his Spiritual Power meets the requirement, but he doesn't have enough points to exchange for a level 5 summoning sigil.

Next, Li Pu came to an agreement with Gan Wenlun.

Both "Iron Bone" and "Golden Armor" would be temporarily housed in the Mechanical Department for rank enhancement.

The bound inscriptions aren't afraid of being stolen by others; Li Pu can retrieve them with a thought. 𝗳𝚛𝗲𝕖𝚠𝚎𝚋𝗻𝗼𝕧𝗲𝐥.𝚌𝚘𝐦

Two days later, the new communications agent Ah Yajun helped him receive Senior Gan's call and then retrieve the upgraded inscriptions.

Among them, "Iron Bone" was elevated from A to A+.

Li Pu tried it out, and the original high hardness was further improved.

Also, its size was slightly larger than before.

If previously the grassman's fist could only wrap around a round piece of black iron, now the black iron has turned into an iron rod, concealed within its forearm.

This way, not only would it enhance the strike strength but also provide good defense at certain times.

Additionally, You Shijin's feature showed itself, that is, now as long as the grassman wishes, "Iron Bone" can become a fluid metal running swiftly within its body.

This way, the flexibility of "Iron Bone" has greatly improved.
