The brave man opened the coffin and rose

Lack of people, lack of people.

Kronos vaguely remembered that when dealing with the Lizardmen's supply points, it was because of the lack of manpower that Lord Abes had no choice but to start a long march and chose to liberate the humans captured by the Lizardmen first.

It is precisely because of the lack of manpower that Lord Abes has been trying hard to explore other races to see if there is any possibility of cooperation.

Of course, this may also be because when this brave hero a thousand years ago led the creatures of the continent to defeat the rule of the dragon, there were many non-human races among his teammates at that time.

All in all, the core of Lord Abes's emotions were the same when he heard that the Lizardmen were not a race that could not communicate, and when he heard that the Goblins were a race that could not communicate.

Because in the face of the vast universe, living beings are always scarce.

And now, facing the possible attack of the lizardmen, Kronos, who was in charge of the affairs of Sweetleaf Town, also felt this loneliness.

Shortage of people.

Tianye Town needs people for production and life, and it also needs people to receive and help those villages with defense construction.

The most important thing is that their greatest reliance, their most fundamental support, Lord Abes, is missing, and they need people to find him.

For this reason, Kronos could only immerse himself in his work and try to forget his worries.

Although the major problems have been solved, there are still many minor problems.

Take the rune set of Magic Blast Furnace for example.

After Kronos taught himself the knowledge related to runes, he took the lead in disassembling the area responsible for charging before Hiiragi and Sister Agatha. In theory, the first step of the problem has been solved.

Next, we will see how to modify the charging area into a new charging area that can adapt to the instantaneous large amount of magic power such as the materialized magic crystals.

It's like converting an appliance that is connected to 110 volts abroad to be able to connect to 220 volts domestically.

But the three people in charge of this research were really stuck here.

Kronos is a half-baked person who has only taught herself for one day. Her idea is to extend the part of the charging area that is responsible for detours and transformation, so as to share the pressure of magic power.

The result is that the duration of time becomes unbearable.

E-sports are the only games that can be played at three frames per second, but if there is a delay in magic transmission, the situation will suddenly change from instant messaging to the hated 1G and 2G.

When a mage casts spells and charges spells manually, he can spontaneously ignore this delay and combine them on his own.

However, the rune sets designed to imitate spellcasting are not the same. As they are mechanical, they cannot receive continuous signals and can only receive intermittent signals, which means they cannot be executed correctly.

It's like the difference between a whole piece of tofu and Wensi tofu after adding a bowl of water.

When there is no water, no matter how solid it looks, it will instantly fall apart when faced with a challenge.

Sister Agatha was completely an outsider to rune group knowledge, she was studying the difference between divine magic and arcane magic. The method she proposed was to carve the rune group on a more solid material while keeping the same carving method of the rune group.

Yes, materials science.

It doesn't matter what you learn about materials, you just have to draw cards. Obviously, there is no time and cost for Sister Agatha to try and make mistakes.

Moreover, Tianye Town is not a mining town with many rich minerals. Being able to produce iron ore and lava crystals is already a great blessing.

Want to find lots of different materials to try and test? That's a good idea.

And Hiinagi?

She suddenly had a burst of inspiration and designed several new charging area rune combinations in succession.

It's just a bit of a loss.

Either you spend enough magic power to activate a fifth-order spell, or you can heat up this third-order fireball.

Either the charging function is perfectly implemented - but you can't release even a single cent. If you want to release it, you need a more bloated release circuit.

It is not so easy to draw out the quick, good and economical ones.

On the other hand, although it seems that all problems have been solved in the production of explosive weapons, some new problems have also emerged.

They just discovered this after making a trial batch.

As for the outer shell and specific means of attack, they designed it quite easily. A double-layer metal cylinder with sharp fillings inside would splash out when the explosion occurred, turning it into a truly terrifying weapon of destruction.

However, after Ms. Hiinagi tried it herself and expressed her satisfaction, Kronos shook his head.

"Too fast, we need to delay the detonation..."

"Delay the detonation?"

Bing Nagi was stunned for a moment, then realized that she had just pressed the switch remotely using the Mage's Hand.

The principle of this thing is very simple once you understand it. After pressing it, a magic crystal inside will fall onto the input port of the engraved rune group.

This module was originally the charging area for the mage in the blast furnace rune group to charge physically. Although it cannot be charged using magic crystals, it can output a strong impact.

Under the action of this impact, the molten crystal explosive will be detonated.

However, because this weapon is only designed to have a space the size of a fist.

From the time the magic crystal is put down, to the time it lands on the entrance of the rune group, and then to the time the molten crystal explosive is detonated, the entire time will not exceed one second.

Bing Nagi has the magician's hand to remotely control, but ordinary people don't have this skill.

Extend the distance in between to lengthen the process?

Then this kind of weapon will not meet the requirements of being small and flexible.

Add a magic to slow down or delay the movement?

That would not meet the requirement of popularization which does not require the participation of mages.

So what about changing all the places that need spells into rune sets, just like the Magic Blast Furnace?

That's impossible!

The three of them spent a long time studying just a simple spell rune set for outputting heat.

As for high-level spells like deceleration or even time spells, they simply cannot separate and apply them in a short period of time.

Even if Abes himself were here, he probably wouldn't be able to think of a solution to this problem right away.

After all, in reality, grenades are delayed using a long fuse.

Here, molten crystal explosives are used for impact.

Kronos asked Wilford again and again, and the fat man assured him again and again that he had told him everything he could.

After all, he was just a sugar merchant. It was good enough for him to know about the molten crystal explosives that were only produced by the military and the royal capital.

He really didn't know how these explosives later became the tools used by the army of the small kingdom of Wommza to throw stones and blast open city gates.

How to solve this small problem is probably the final hurdle in the issue of weaponization of explosives.

The above things are the small problems they face after the previous big problems in principle have been solved.
