The physical effects caused by Spirit Power were not true physical effects.
After all, ice-attribute Spirit Masters could use Spirit Power to lower the temperature out of thin air. That clearly did not fit the second law of thermodynamics.
But the physical effects created by different attributes still carried a great degree of physical traits.
The flames of most fire-attribute Spirit Masters could not burn in a vacuum, nor could they ignite under seawater.
Only some special flames could burn in special ways.
Since he was going to start climbing the technology tree, Chen Ming decided to begin with the most basic methods.
Using the ores he had mined and the various materials he had stored, Chen Ming directly built a huge steel furnace and a special charcoal kiln underground.
With this huge steel furnace, Chen Ming could heat flames to around 2,400 to 2,500 degrees Celsius, instantly melting and refining most metals.
In the Douluo world, this temperature had already surpassed Ultimate Fire. Even a Limit Douluo who stepped inside would find themselves in severe difficulty.
(PS: This has already been greatly strengthened. In the original Yin Yang Crown, the Earth Core World was considered high-temperature at only 80°C, and the Ultimate Fire of the Douluo world could not even reach 100°C. The sun in the Douluo world is not nuclear fusion either, but a huge ball of fire. According to the setting, this temperature would actually be enough to instantly kill a LimitDouluo.)
Because he was no longer anything close to a normal human being, the design of this large steel furnace looked somewhat suicidal from the outside.
To activate it, Chen Ming had to station himself inside the furnace and personally release his own flames toward specific points, initiating the combustion reaction.
As for refining metals, Chen Ming had to control the flames and the metal at the same time, using both fire control and metal control to operate the furnace.
Operating this thing required not only the immunity Chen Ming had gained after tempering his body with ice and fire, but also advance preparation.
He had to enter a state of internal circulation, using a special operation of Spirit Power to temporarily cut off his need for oxygen.
Otherwise, without oxygen, he would not be able to last long.
This was not Chen Ming's own problem.
This was a problem with the Douluo world.
As for fuel, Chen Ming chose coke. He used finished charcoal he had bought earlier and processed it a second time in the charcoal kiln. Because Chen Ming now had detailed perception, along with fire and earth attributes, refining coke was extremely easy for him, and the quality of the coke was also higher than normal.
As for why Chen Ming did not consider using heavy oil? The key point was that although Douluo Continent had very special material science, it truly did not have petroleum.
It was as if the substances that should have formed petroleum had, because the laws of this world were different, turned into other metals during their formation.
Even coal was relatively rare in the Douluo world.
The large coal mines discovered in this world were only at the level of small mineral veins in Chen Ming's previous life.
After all, even the physical constants of this universe had some issues.
That was why, after all these years, Chen Ming had never been able to make high-tech things like computers.
He could only slowly understand the physical constants, the operating rules of the Douluo world, and the current level of technology first. Then he had to adapt the knowledge from his previous life before applying it here.
The key problem was that the lack of petroleum hurt too much.
One had to know that petroleum was the blood of industry. The progress and development of an entire industrial civilization depended on that black gold. Since Douluo Continent had no petroleum, Chen Ming could only think about whether other things could replace it.
...
After spending more than two days pretending to be Sun Wukong inside the furnace, Chen Ming sadly discovered that all the metal in his hands had already been refined.
He had nothing left.
The furnaces in large steel plants could produce 120 tons or even more in one batch. Even the furnaces in small steel plants could produce 30 or 60 tons in one batch.
Compared to those huge things, Chen Ming's furnace was already very small, but it could still produce around 10 tons of steel at a time.
Over the past few days, Chen Ming had basically been running the furnace almost empty, using it only to refine a tiny bit of rare metal.
This was like using a 5090 graphics card to play Gold Miner.
He had barely used any real power before all the materials were gone.
"Do I still need to mine a vein myself? As expected, mining should be handed over to the Seven Treasure Glazed Tile Sect. Each one of them is born with the body of a mining saint. I'll just handle the technical side."
Chen Ming quietly complained, then took the various metals he had refined and began testing alloy combinations.
Using his control over metal, he directly made the metals change shape under his command, growing into the required mechanical forms.
Before long, something similar to a hand cannon appeared in Chen Ming's hand.
It was a "high-density solid metal energy projector" that Chen Ming had made with a high-energy conductive metal core fused from several metals.
In simpler terms, this thing was a launcher that could fire a 30-gram solid projectile at three times the speed of sound through electromagnetic force.
Although its effective killing range was only about 2,000 meters, and once it passed that distance, its power would start to drop sharply, Chen Ming estimated that if someone was hit by it within 1,500 meters, even a Spirit Saint using Martial Soul True Body would have that True Body blown apart by one shot.
Most likely, they would explode on the spot.
Even if their Martial Soul True Body was special, they would at least fall into a near-death state.
If a Title Douluo took a shot from this thing, the protective Spirit Power around their body would be shattered, and their body would be pierced through. The odds of survival were low.
This thing wasn't particularly important in itself — but its existence was.
Because with Douluo's extremely twisted material science, Chen Ming could even enlarge this thing dozens of times and fire a projectile with a caliber about the size of a human head.
With one shot, even a Limit Douluo might die.
Unless they had some rule-type ability, teleportation, or an immortal body, even if a Limit Douluo tried to block it with Spirit Power, the result would likely be "blood escape and retreat."
The metal projectiles Chen Ming currently used had excellent conductivity, so they could be fired at high speed under these conditions.
Just like the earliest cannons fired stones, with the progress and change of technology, pure metal projectiles could also be replaced with explosive shells, further increasing their power.
Of course, since this was a fantasy world, the technology could also be adjusted a little.
Or perhaps he could slightly modify the conductive Spirit Power metal, turning it into a soul tool that released a special field, then fire it at high speed?
Directly transforming it into a hybrid weapon with both kinetic force and a field?
If he could create a small field, then the air resistance against the metal projectile would greatly decrease.
It might even reach nearly zero for a short time.
Under the same launching equipment, the firing speed could rise by at least two to three times. Combined with the projectile's inertia and the field itself, it would probably be able to pierce through many terrifying things.
