Able followed Bernie through the teleportation circle to a teleportation circle, which was supposed to be a hidden place of the Gough family.

You must know that teleporting in through the teleportation circle and the close teleportation circle will not reveal the location of this place, which is a way to keep the important area secret.

Able came to an underground area, and the light came from more than a dozen ground fires that drew from the ground around him, reflecting the entire underground area in fiery red.

The underground area was very large, surrounded by stone walls, and he could see the chisel marks on the stone walls, and he was surprised to find that this underground area was probably directly excavated by the dwarves.

This underground area is tens of meters high and hundreds of meters wide, and it is still a hall room, with more rooms on the side.

"Abel, this is our family's secret research office!" Bernie introduced Abel with a smile.

He could see the surprise in Abel's eyes, which made him very proud, and the dwarves were never open to the outside world only for the surface buildings, such as the caves dug out of the ground, which were never shown to the public.

The caves that have been dug are the foundation of the Dwarves, and as long as these caves exist, the Dwarves will not perish.

The dwarves' ore and various materials were obtained from these caves, and it was because of countless years of excavation that the dwarves learned how to build strong caves in the middle of the mountains.

"Bernie, the Sky Boat is studying here, why can't you see people?" Abel looked left and right, but didn't find any other dwarves there, as if this was an abandoned cave, so he asked strangely.

"This place is sealed, the materials for the Sky Ship are ready, but the metallurgical materials for the main circle are not, everything is nothing, and this place has become a material warehouse for the Sky Boat!" Bernie introduced.

"You called me here to help you refine the metallurgical materials for the main circle?" Abel asked rhetorically.

"Abel, follow me!" Bernie nodded, pointing as he walked forward.

He followed Bernie to the other end of the hall, where a black-gray stone block about three meters high and three meters wide was inlaid on the wall, and some ancient characters and patterns were carved on it.

Abel noticed that the most striking thing in the pattern was a huge airbag under a boat-shaped house, and on the side of this pattern was a dense detailed drawing of each part.

He read it quickly, and he memorized all the structural drawings of the entire Sky Boat, and also discovered the metallurgical method of the main circle material that needed his help.

As many as eighty-eight different materials, after hundreds of metallurgical refining processes, the difficulty was many times more complex than that of any metallurgical material he had ever seen.

"Abel, this is what we discovered when we were digging an underground mine, and after discovering the construction method of this Sky Boat carved in stone, this place was sealed off by our family and became a material warehouse for Sky Boat, just waiting for the Sky Boat to fly into the sky one day!" Bernie said as he gently stroked the black and gray stone in front of him.

"The metallurgical materials of this main circle are very troublesome, and I am not 100% sure!" Abel said in a deep voice as he looked at the metallurgical method of the main circle materials.

From the metallurgical method, he saw eighty-eight kinds of materials, most of which were very precious, some of which he had never heard of even as a blacksmith master, and some of which he had heard of only through books, but had never seen the real thing.

If you want to collect all these 88 kinds of materials, the manpower and material resources will be astronomical.

And eighty-eight materials, hundreds of processes, none of which can go wrong, can make almost any alchemist despair.

And even Abel, who never makes mistakes, does not dare to guarantee that it can be successfully refined at one time, because there are too many unknown materials in it.

"Abel, among the materials of the entire Sky Boat, the most precious is the metallurgical materials of the main circle, and we have only collected ten of the eighty-eight materials in countless years!" Bernie said.

Bernie also knew how difficult it was to refine, and he understood that if Able couldn't refine the metallurgical materials of the main magic circle, there might not be any alchemy master who could refine it.

Abel couldn't help but hesitate a little when he heard that he had only collected all ten materials, because even if all ten materials were completed, he would only be able to make ten sky boats at most.

What is the purpose of ten sky boats, if you want to build another transportation network, the number of sky boats needed is far from what ten sky boats can reach.

"Abel, you don't have to worry, it doesn't matter if you fail, if you can't succeed once out of ten, at most wait for a few decades later, and then we will collect materials and refine them. Bernie saw Abel's hesitation and thought he was worried about failure, so he persuaded him.

Abel couldn't help but be stunned, what is the situation, it is not required to succeed ten times, looking at Bernie's appearance, as long as ten materials are refined into one main magic circle metallurgical material, he will be satisfied!

"Okay, I'll do my best!" Abel said with a smile.

At this time, he found that the surface of the black-gray stone block took up more than half of the space with the construction method of the Sky Boat, and the other half was another relatively simple item.

It is a diagram of a weapon made like a cannon on Earth, and as you can see from its description, it is an extremely powerful long-range weapon.

"Bernie, did you build this?" Abel asked, pointing to the weapon-making diagram beside him.

"Abel, that's the powerstone cannon, a cannon made of powerstones as raw materials, the weapons masters in the family have long studied it, this powerstone cannon may have been a very powerful long-range weapon in ancient times, but now this powerstone cannon is impossible to make at all, even if it is made, it is impossible for anyone to use it!" Bernie said with a wry smile.

"Why, I see that in the description of this powerstone cannon, the power of this powerstone cannon is almost nothing to resist, and it still varies according to the level of powerstone, if the top powerstone is packed into this powerstone cannon, who else can live if this cannon goes down?" Abel asked curiously.

"Abel, don't you see that the entire cannon body is made of master metallurgical materials, not to mention how difficult it is to obtain the materials needed for this cannon body, even the use of this powerstone cannon is also problematic, according to the analysis of the family's weapon masters, after this powerstone cannon is used once, the entire cannon body will be destroyed, which means that this is a one-time weapon!" Bernie shook his head and said.

Able couldn't help but gasp, is this ancient race crazy, and even set the powerstone cannon made of master metallurgical materials to have the ability to only hit one hit, could it be that there were so many master metallurgists in ancient times, and materials were everywhere?

"War Commander Spirit, do you know this magic stone cannon?" Abel's heart moved, and he thought that the War Commander Spirit on his body was the spirit of that era, and he could ask it.

"Your Excellency, the Powerstone Cannon was forbidden in ancient times and was forbidden to be used in any battle, but at that time, many families would use it as a last resort for their families to protect themselves. The War Commander Spirit explained to Abel through his psychic powers.

Abel knew what the magic stone cannon was at this time, this was an atomic bomb-like existence, powerful but only one hit, which was forbidden in ancient times.

However, one thing he was very sure of was that if this powerstone cannon was powered by a perfect gem, its power would be much more powerful than that of a super explosive ball, because one was to detonate its own power and spread it around, while the other was to enhance the explosion power of the perfect gem through the magic circle pattern engraved on the cannon, and then its explosion would be directed and concentrated.

"It's a pity!" Abel couldn't help but sigh and said, if this magic stone cannon is not a one-time item, then spending the cost to make one can become another killer feature for him.

"Abel, if you are interested, I can be the master, we have collected a complete set of materials for this magic stone cannon for analysis and evaluation, this set of materials is still stored here, if you need it, I will give it to you, anyway, it is useless for us to keep it!" Bernie said with a smile when he saw that Abel was interested in the magic stone cannon.

Abel smiled, he didn't believe that there were any materials that were useless, master-level metallurgical materials, plus other manufacturing materials of the Powerstone Cannon, even if they were not used on the Powerstone Cannon, they were extremely precious materials.
