The three of us were in the lower dungeon of the castle.

Locked up but not chained. We were alive and together and sheltered.

People came and went to see us. Some insulted us but we managed.

They brought us vegetables and we made soup, broth and we loved it, it was a change from the food that was bursting in our mouths and this permanent feeling of death.

We learned to play chess, to sing but we had to stop quickly and we learned a lot of things like reading a little better, articulating to speak etc.

My sisters made small works like boxes, baskets, nets, basically they made objects not too precise but imposing.

They learned masonry and carpentry. When they saw dragons working, their image slowly changed, but they could never erase the dead.

We were in the service of the prince, to whom we obeyed at his fingers. But this time of our own free will.

We didn't dare to leave the castle, even to hunt, and we took refuge in the dungeon, deep inside.

Terrorized.Then I got tired of it and asked to see Mandrake.

Mandrake came to me and asked me why I wanted to see him.

I told him, "we can't live like this in fear anymore.I can't take it anymore! And he's going to come for us this time .We have to work together. "

Mandrake: "But how? You are a dragon, an enemy."

Me: "I don't care, you said relics from before the cataclysm. I want to see them! We could do something.But there are yellow skulls on them and you die quickly after, they are cursed."

Me:" In my time, magic and curses did not exist! Only science existed. I was a scientist, a mage basically."

Mandrake directed me to a huge cellar and I could see a lot of different objects and the famous yellow skulls: they were nuclear waste.

Ah, I understand

Let's sort it all out

Ah, I see lead armor.

"There is nothing cursed, the radiations that are released are like an invisible fire that cooks and burns without knowing it. You need lead to protect yourself from it, lead and concrete."

Mandrake "ah, edifying And the treatment? "

"Rinse, wash and remove any metal object on you and dip it in the river to release the energy. Swallow iodine, lots of shellfish and fish and drink lots of milk. Urinate a lot."

"Noted.What is this?"

Mandrake showed: screwdrivers," they will turn here and there."

"And this?" "WrenchesSocket wrenches,They are damaged and ruined, but even if it's rotten with time, everything retires."

"What is this big snake?"

"Electrical wire."

"Electric? Yes, to carry the lightning. What's this picture, we tried to translate it but we don't understand anything"

"Ah, great, it's a Mendeliev table, a classification of materials: look here: Hydrogen, Oxygen, Iron, Gold, Silver.And water, No, water is composed of H2O and you see this book has all the formulas of alchemy but a thousand times more advanced. And here a plan for experiments. The wires are good but the rubber falls to dust. And this is like fat but it's poison. No, this is industrial oil. Very useful. It's a grease for metal parts. OHH a big generator. HAHA, this will make dad burn! It's an engine!"

"we use fluid grease that will explode and move a tube that will turn a crank and return to its starting point. and it will turn with a lot of force and quickly. We can make a mechanical and electrical workshop. Basically, you're going to advance 2000 years into the future.Right?"

"Yes, we'll make a lightning generator so that when daddy comes near the castle he'll get his tail fried! Or he'll fall like a burned fly. But to kill him it won't be enough, I need a cannon"

We searched and found some shells.

"Ooh, be careful Mandrake, these are very powerful weapons. With time they are unstable and with the slightest shock you can die. You'll need a tool to pierce the tube remotely and recover the contents, re-grease it so you can use it again. But no embers or sparks and boom, you're in a million pieces. I know the formula to make it"

"Oh a tank "

"Well Mandrake, we'll have a long time to get this thing in working order. You know what I mean? We're going to use the cannon which is millions of times more powerful than your catapults and millions of times faster. Father won't be able to avoid it and no shield will be strong enough to protect himself. Let's give you a demonstration."

There was an old field gun and I took the gun out and positioned it on the rampart. I aimed at an old ruin 1km away, I used the sight and made the tilt adjustments. But I'm not crazy, I took a long string for the firing pin and placed an explosive shell.

The Prince, Mandrale and the King watched the cannon fire, they didn't understand why I asked them to cover their ears, but then they understood.

Then they saw the damage 1 km away.

I told them that in the past, some castles had cannons that fired directly at other castles without using troops.

The ruin was pulverized and burned.

Then I found a sniper rifle and put it back in working condition, all oiled.

The old rubber was soaked in burning oil and it vulcanized again, the electric wire too.

The generator was repaired and the engine was unstuck.

The lathe was assembled and the batteries were rebuilt with lead and zinc plates. For the acid, the salts in the bottom were collected and rainwater was added.

The batteries started to work again and the engine started to run again after centuries of stoppage.

Everything had been carefully dismantled and reassembled according to my instructions.

With electricity, other generators were rebuilt by apprentices who watched how I did it, and I started up a lathe, a milling machine and a numerical control again.

The king and mandrale were amazed to see these machines reborn.

Then, with the tools, we made lifting devices, cranes and overhead cranes. Windmills and electric motors were also built for a high tech workshop.

Mandrake had regained his youth and drowned in the deciphered readings of chemistry and physics and especially of the pc with its enciclopedia, the paper was reinvented, the printing too and

ESPECIALLY WE LACKED TIME

Finally the tank was put back in operation, and copied to make turrets.

The cannons were mass-produced with shells. And the tank was equipped with refractory ceramic tiles against the blast of the father. Also the tiles were hollow with cooling water connected to the engine.

I tested myself the resistance of the armor with my concentrated fire. After several tests, the tank was invulnerable to the dragon's breath.

We built self-supporting guns with light armor and tiles in series.

Then came the fateful day

"GROOOAAAAAr,"

IGNAR and SANGUINEMA together with armor made by orcs or demons arrived and followed by a horde of undead.

"morons i have waited a year for you to come back! YOU WILL BE PUNISHED FOR JOINING THE HUMANS

I PROMISE TO TEAR YOUR WINGS OFF YOU DANTINNE AND TO RAVAGE YOUR BELLY RUBY AND SANGUINE! YOU WILL LAY DRAGONS UNTIL YOU DIE

NO MORE EXCUSES!"

Mama trembled and so did Ruby and they fled into the dungeon.
