Of course, Barnett was only imagining, and it was not easy to gather the materials for the 100,000 parts, and even if Barnett had collected a large number of rare materials during his two thousand years of travels, those were only one-tenth of the huge number of materials needed to build a defensive heart.

Barnett knew better than anyone that the more precious the materials used to create the Defensive Heart, the better the defensive effect of the Defensive Heart, and the lower the likelihood of creating vulnerabilities, which Barnett even began to calculate which of his existing materials did not meet the "requirements", which materials were not enough and needed to be supplemented, and even which materials could be replaced with better ones......

After some calculations and comparisons, Barnett was saddened to find that there were less than one percent of the materials in the library that he had been complacent, which undoubtedly made Barnett, who regarded collecting treasured materials as one of his two great pleasures—his other pleasure was, of course, collecting fine wine, and it was clear that he put more effort into this pleasure and gained more fruit.

In fact, Barnett made a big mistake here, that is, too much pursuit of perfection, which is a common problem in almost all production professions, and wants to use the best materials to make the most perfect products, but he does not know that such an ideal is almost impossible to achieve.

Even when Kenobi asked Barnett to build the parts he needed for the first Heart of Defense, he didn't always use the best materials, and Kenobi embraced the principle that "the right is the best." ”

Of course, this is all for later, and the current priority is to use the Nether Cold Iron provided by Anthony to first build a defensive heart core according to the drawings to pass Anthony's test, otherwise everything is empty talk.

Since Anthony took this as a test for Barnett to pass the level, he naturally had a certain degree of confidence that he could stump him, after all, Anthony had no way to use this piece of Nether Cold Iron in the Flame Furnace composed of hundreds of flame essences.

Of course, it cannot be ruled out that Anthony deliberately used the milky white flame in Barnett's hand to smelt this piece of netherworld cold iron, provided that he did know the origin of the milky white flame.

Barnett couldn't have thought so much in his head, and the limit he could do was to think about how many materials he could withhold in the process of smelting this piece of Netherworld Iron and using it to build the core of the Heart of Defense.

Sometimes the dwarves are so naïve and persistent that he even dares to take a huge risk to withhold the treasured materials of a Sanctuary powerhouse......

Barnett closed his eyes and reviewed the construction diagram that Anthony had just shown him, and after making sure that every detail was accurate, he suddenly opened his eyes and said confidently: "Then let's start!"

A wisp of milky white flame emerged from Barnett's fingertips, forming the shape of a knife, slowly approaching the Netherworld Iron, which was unscathed under a hundred flames, and was easily cut off in front of the milky white flame like fragile butter.

It seems that Barnett's milky flame is indeed the nemesis of Netherworld. As soon as the small piece of Netherworld Iron was cut off, the flames in Barnett's hand immediately changed shape, enveloping it like a large net. The milky white flame only shook slightly, and the incomparably hard Netherworld Iron turned into a puddle of molten iron.

Barnett carefully controlled the flames, and the Nethercold Molten Iron changed shape in the flames, gradually turning into a flat part.

As soon as Barnett raised his hand, his set of forging tools reappeared beside him.

Barnett took off his shirt entirely, revealing a knotted muscle, beads of sweat running down his bronzed muscles. He began to use a small, palm-sized hammer to pound the rough blank of the intricately conceived part on the anvil.

Ostensibly it's just a flat round gear, but it's actually hollow, and it's engraved with magical symbols for some unknown purpose. Of course, this is a diagram on the construction drawing, and what Barnett is doing now is to bring the drawing to life.

Barnett had to be thankful for the milky flame, if it weren't for this powerful flame, he would have been helpless to face the Netherworld Iron like Anthony. He may be able to reluctantly get a piece of Netherworld Iron to build it with his superb skills, but it will undoubtedly take a huge amount of time and energy, and it will be a completely cost-effective act.

What was even more unacceptable to Barnett was that it would waste a lot of Netherworld Iron, as in many places he needed to use a harder grinding stone to grind off the excess, and the reuse rate of those debris was quite low.

Presumably, Anthony has always kept this piece of Netherworld Iron so intact that he has not taken this aspect into account.

Now with the help of milky flames, everything is much easier. This flame, which had almost been connected to Barnett's fire of life, was as dexterous and convenient as a finger under Barnett's command.

In the process of forging, any excess part of the Netherworld Iron, as long as Barnett's mind turns, will immediately be cut off by the milky white flames, and the cut crumbs will immediately be collected by Barnett re-smelting the flame into molten iron, without causing any waste.

Of course, most of the Nethercold molten iron smelted from these detritus was unknowingly put into Barnett's pocket.

"It's a bit redundant...... Here too...... I think it's better to make it a little thinner......" In Barnett's muttering to himself, the oblate core took shape quickly, but it was undoubtedly much smaller than the raw material Barnett had cut from the Netheriron, and as for the remaining scraps...... Barnett snickered inwardly as he built the parts.

"It's not as difficult as I imagined, why did Mr. Kenobi keep saying that my skills don't meet the requirements of building the core, and refuse to teach me the construction diagram?" Barnett looked at the first part of the core with satisfaction, and complained with doubt.

Of course, the careless dwarf would not have imagined that his skills had been honed for more than two thousand years, to the point of perfection, and that the tasks that he could not do before could now be easily accomplished. It's just that in his own eyes, his skills have always been so good.

If Alfie were here, he would have doubted that since Kenobi had Barnett build all the parts of the entire defense system, who would have given the core to complete?

"The first one is done, then the second one ......" Barnett recalled the construction drawings and decided to pick a larger part this time, so that he could cut a larger piece from the Nethercold iron, and the scraps......

Barnett had a sly smile on his face that the dwarves had never seen before.
