Ling Tian patiently explained to the several craftsmen.
First, the greatest advantage of the magic core bomb was its universal applicability.
Although Ling Tian had a wide variety of talismans, if a person had no magical power or had not mastered the method of using true essence, they could not inject energy into the talismans to activate them.
Furthermore, talismans required a lot of true essence to be injected into them to activate. Take Zhang Caifeng, for example. Although she had been cultivating since childhood, after releasing more than ten talismans consecutively, her true essence was depleted. For a cultivator, running out of true essence in battle was extremely dangerous.
The magic core bomb did not have this problem. Theoretically, as long as the user had the strength to throw the device more than 30 meters away, ensuring they wouldn't be killed by the explosion, they could use it in combat without expending any true essence.
Another advantage of the magic core bomb, and the primary reason Ling Tian favored it, was its low cost and mass-producibility.
While magic cores were not cheap, they were plentiful now. Ling Tian had not turned in all the captured magic cores to exchange for points; instead, he kept many for himself.
There were also many low-end magic cores in the Spirit Realm space. These magic cores had very low purity, and some even possessed multiple attributes. Such magic cores were not suitable for direct absorption and use.
When absorbing impure magic cores, not only was the absorption rate very low, leading to waste, but absorbing magic cores of different attributes could also cause mutations. Most of these mutations were negative.
With the magic core bomb, Ling Tian could make use of these low-quality magic cores by turning them into magic core bombs.
The most expensive component in a magic core bomb was arguably the magic core itself. Ling Tian had plenty of them and could supply them without limit.
Additionally, the metal needle inserted into the magic core required extremely high hardness. Although such items were costly outside, within the Spirit Realm space, with these skilled craftsmen, it was not a problem at all, and the cost would be minimized.
As for engraving formations on the magic core, this was very dangerous and difficult for outsiders. However, in the Spirit Realm space, there was a master engraver who found engraving formations on it as easy as eating and drinking. This would also infinitely lower the cost, allowing for mass production.
One reason Ling Tian opposed the craftsmen making major improvements or upgrades to the magic core bomb was the cost. If the cost became too high, the value of the device would be greatly diminished.
On the other hand, if the device's power were increased further, and its kill radius expanded, it would mean that using such a weapon would require greater distance from the opponent, which would undoubtedly increase the user's danger and narrow its application.
After Ling Tian's explanation, the craftsmen immediately understood his intentions and went their separate ways to produce the related parts.
A few hours later, a batch of parts was produced and sent to Qiao. Qiao, with astonishing speed, assembled several magic core bombs.
Next, Ling Tian led everyone to an open space outside the Spirit Realm Mansion to test the power of these magic core bombs.
Ling Tian first pressed the button and threw out the original magic core bomb, the one he had obtained from the Slaim camp.
"Boom!" The bomb exploded on the spot. Centered around the bomb, sand and stones flew in all directions within a 20-meter radius, debris scattered everywhere. The ground at the center of the explosion was blasted into a pit more than 10 centimeters deep.
Ling Tian nodded. The power of this device was indeed much greater than that of a hand grenade.
Immediately afterward, Ling Tian pressed the button again and threw out a magic core bomb produced by the Spirit Realm space.
Because this magic core bomb had been improved, its detonation time was delayed from 5 seconds to 6 seconds after activation. This allowed the bomb sufficient flight time in the air, which was also for the user's safety.
"Boom!"
This new version of the magic core bomb exploded upon landing. The blast radius reached over 30 meters, and the pit at the center of the explosion was half a meter deep. Ling Tian was very surprised by this result.
"Qiao, did you use a larger magic core?"
"No, Master. We followed your requirements. The magic core is roughly the same size as the original one. We only optimized the formations on it.
Additionally, we made some minor adjustments to the internal structure to allow the bomb's power to be released more evenly and reasonably during the explosion...
According to our calculations, after making these minor adjustments and improvements, the explosive power of this device has increased by about thirty percent, with no increase in cost..."
Ling Tian happily slapped his thigh. "Good, Qiao, produce a hundred of these for me first. From now on, in the Spirit Realm space, ensure a minimum stock of one hundred. If it drops below that, produce more immediately!"
"Yes, Master!" the butler beside him replied.
Ling Tian pondered for a moment, then turned to Qiao and said, "Qiao, produce a few more with enlarged magic cores. Pay attention to the size of the magic core and ensure the explosive power is controllable and predictable."
"Understood, Master, I will!"
Having resolved the mass production issue of the magic core bombs, Ling Tian then took out the Frost Staff and demonstrated its use to the craftsmen.
Holding the Frost Staff, he injected true essence into it. A gem on the Frost Staff flashed, instantly activating the formation. Then, an ice cone over a meter long shot out, piercing a tree with a diameter of over half a meter in the courtyard. Shattered ice shards froze all the other branches and leaves of the tree.
Next, Ling Tian injected ice-attribute true essence into the staff.
Although Ling Tian's cultivation technique, the Blazing Flame Art, was fire-attribute, and most of his true essence was fire-attribute, his current cultivation level allowed him to change the attribute of his true essence through some minor techniques. However, the efficiency of releasing true essence in this manner would be halved.
As Ling Tian's true essence flowed into the staff, the dim blue gem on the staff slowly began to brighten, regaining its original luster.
"Do you see? This thing called the Frost Staff, although powerful, requires someone who has mastered ice abilities or ice-attribute true essence to inject true essence and replenish its energy. Its limitations are very significant.
I hope you can use your brains and improve this item..."
