Few Weeks later.
"Are you sure you want to learn blacksmithing?" Jon asked Montu and Robb also looked at him from side wanting a answer.
"Yes, I have many things in my mind to create, if those inspirations are created successfully, I can become richest in the world." Montu replied and entered the Blacksmith shop after bumping fist with both Robb and Jon.
"You're the boy Lord Stark send me to learn blacksmithing?" A old yet muscular man with big arms and tanned skin asked Montu.
Montu nodded.
"Ok, here is the Iron piece beat it and remove all impurities." Old Blacksmith handed Montu a Iron piece and signalled him towards anvil in another side of shop.
Montu took the piece of iron and after putting it on anvil, picked up the hammer which was heavy but manageable and started beating the shit out of Iron piece.
But only after dozen beatings, his hands became sore.
"Haha, boy your hands and body is weak, also your stance is wrong, you should do it like this." Old Blacksmith laughed and did the hammering slowly for Montu to see.
"Did you memorized the stance I showed you just now?" Old Blacksmith asked.
Montu nodded and sat down for rest.
'Looks like I will have to start training this body.' Montu thought as he rested and looked at the iron piece he just hammered.
'Once Steam Engine is made, I will make a furnace powered by bellowing by Steam Engine, heating the Iron and other metals very high hot and many impurities will be extracted with just heat and purest Iron will be produced by me in the world, than I will make a hammering machine powered by that steam engine and shape iron easily.' Montu thought giving himself a mental boost with future thoughts where he is sitting on Tank powered by steam engine and Tank is firing non-stop at white walkers of Night King, blasting them to pieces easily.
'But Night King and his creations can only be killed by Obsidian and Valerian metal, well just fill the bombs with Obsidian Shards or make bullets and shells filled with obsidian, it will directly kill them, hehe.' Montu thought.
'But I will have to mine Obsidian from Dragonstone, well let's do it after Stannis is dead.' Montu thought.
...
Two months later.
Montu put the dumbbells down and started doing another practice.
He has been doing various types of practice from past two months and he can feel his strength increasing at fast pace.
He was surprised by his body but thought it maybe a gift for transmigration.
He has been doing many practice and one of them was Yoga to increase his flexibility along with strength.
He don't want to become a brute who has strength but no flexibility.
His body always feels full of energy and he is slightly addicted to both practicing and hammering.
...
Three years later.
Broken tower.
Montu has made his lab at top of Broken Tower, with no any modifications outside the tower.
At first he was hesitant, whether Lord Stark will let him use the tower for his use.
When he told about this problem to get himself a private lab, where he can smith the metals himself with no anyone beside him and silent area.
Robb patted his chest and said that he will ask his father to get Montu a lab and asked where he wants to make his lab.
Montu mentioned Broken Tower and Robb immediately left for his father.
Jon assured Montu that he will be given the tower for his use as it is abandoned for a long time, but is not in bad condition.
Next day Lord Stark called Montu and asked why he wants the Broken Tower as his lab and for smithing.
"Lord Stark, I want a empty place where no one goes and is big enough for my use and I want area where air is abundant, my work will be very loud so Broken Tower is perfect for me." Montu explained.
Lord Stark nodded and asked his men to deliver all goods to top room at Broken Tower and clean it up.
Montu said that he only want the top room at tower to be cleaned, no other places.
Lord Stark paused but nodded as it reduced much work for his men.
Montu was now hammering a rod with precision and after it was done he picked up the iron rod using long tongs and put the iron rod in water to cool down quickly.
Steam rose as hot rod touched the water.
After a few seconds the steam stopped rising and Montu took out the rod and put it on his workbench.
He fixed the rod on steam engine and stepped back to look at it.
Frame, Cylinder, Steam Chest, D-Slide Valve, Inlet and Exhaust ports, Pistons, Crankshift, Flywheel, Valve Gear, Condenser all were done, making a complete steam engine.
Montu picked up the bucket carrying Charcoal and put it in the firebox and threw a burning stick from Fireplace in the Firebox and closed the lid.
He stepped to other side of Steam Engine and started turning the wheel with his hands and Steam Engine started working as air from other piece called mechanical blower was blowed into the Firebox.
Firebox started heating at fast pace.
Ad when steam started to rose, Montu stopped turning the wheel and removed his hands, the wheel now was speeding up slowly and more and more steam was rising up from the top of pipe installed on the steam engine.
Montu picked up another blower and connected it to wheel of Steam engine and turned it to big furnace.
The charcoal in furnace which was burning slowly started to burn fiercely as air was being pumped quickly in it.
Montu threw more charcoal in the furnace.
As heat started increasing in the furnace and noise of Steam Engine roaring loudly throughout the Winterfell.
Montu looked at the iron pieces in the thick bucket in the furnace.
Iron pieces were melting at fast pace, and whole room which was cold and big started heating quickly.
Montu started sweating and looked excitedly at the iron being melted.
After half an hour as thirty kilograms of iron melted.
Montu stopped the air pump and turned the bucket carrying molten and pure iron into the slab on the ground where he has created big hollow shapes.
Yes these hollow shapes were parts for the next generation Steam engine, which will made by more refined and stronger iron.
As soon as iron was emptied in the hollow shapes, he put another steel pieces in it which he made so Molten Iron will not stay at one place.
Few hours later, Iron cooled down and Montu looked at new parts for his next generation Steam Engine.
He also shaped the rest of molten iron into rectangular bricks, thinking of giving them to his master blacksmith, who taught him blacksmithing with all of his heart, although instructed by Lord Stark.
