Lynn walked slowly onto the high walls of Fire Oil City, the best vantage point to observe the explosion. Only wizards and some of the guards were privileged enough to climb up here.
"Is everything ready, Speaker Vittorio?" Lynn didn't rush to meet everyone's expectations and display his new magic but instead asked cautiously.
"The Formation I was instructed to set up is complete!" Vittorio's expression was just as grave.
Although hydrogen bombs are different from nuclear bombs and do not have a so-called critical mass, in theory, even one gram of deuterium could explode. But until he broke through to the realm of legend, he obviously couldn't control it at will.
This time, the Hydrogen Explosion spell also used an 'ancient' and 'simple' method—using an atomic bomb as a detonator to trigger the hydrogen bomb!
That meant the yield of the hydrogen explosion couldn't be too low, about equivalent to the explosive power of 300,000 tons of TNT, fifteen times that of the previous atomic bomb!
The radius of the destruction, even by the most optimistic estimates, would be over twenty kilometers!
In other words, if left unrestrained, the entire Fire Oil City would be swept up in the powerful wave of energy...
It was for this reason that he had Vittorio set up an Alchemy Array at the center of the projected point of explosion, to confine the power of the nuclear blast or, in other words, artificially restrict the spread of the energy wave, to release most of the hydrogen bomb's might at the core.
This was also related to Lynn's envisioned use of the Hydrogen Explosion spell in a new way. If the experiment was successful, there might be no need to resort to such a mutually destructive method to kill the enemy next time!
As he contemplated, Lynn slowly rose into the sky under the watchful eyes of the crowd.
The kingdom's citizens watching were all abuzz with speculation. Some thought this Star of Magic was preparing to fly up into the sky and bring down the Sun, while others thought Lynn was summoning a meteorite to fall, for only such power could create the terrifying Land of Death.
The few Speakers and over a dozen Grand Wizards were focused intently; they were responsible for stopping the horrific energy backlash if the situation turned worst.
The most relaxed individual present... oh no, energy beast, that would be Mutuo. It did not care what these bipedal creatures were doing. Upon reaching the top of the fortress wall, it simply found the widest and most comfortable spot and lay down.
The intense heat from its body made the wizards nearby instinctively give it a wide berth, turning the already crowded space on the fortress wall even more cramped.
Yoland and the others were angry yet dared not speak out. After all, the creature was Lynn's 'pet,' rumored to be capable of gobbling up several incredibly hard and extremely dangerous radioactive elements like beans. Any wizard with a bit of sense understood this strange magical beast was not something they could handle.
After only a brief delay, Lynn had already flown up a hundred meters into the air. This time for the Hydrogen Explosion spell, he chose not to use a clone explosion method, but was instead preparing to project it directly!
Lynn opened his hands, and his domain as a Grand Wizard instantly expanded to a hundred meters around him. Next, the stored uranium elements, deuterium, and tritium began to rapidly converge, followed by a surge of magic power, which mimicked and formed an elliptical shell...
It took no more than a few seconds, and a hydrogen bomb warhead appeared in front of Lynn, with near-critical mass of uranium-235 and elements of deuterium and tritium placed at the two focal points inside the elliptical warhead.
"Thunder!" Lynn spoke slowly, and intense lightning became visible around.
Yes, his method of long-range projection was none other than the electromagnetic cannon!
Due to material limitations, this device had a maximum range of only twenty-five kilometers.
But this 'only' is compared to the thousands or even ten-thousands of kilometers range of missiles; a strike from twenty-five kilometers away was already terrifying in this other world!
Nevertheless, there was a prerequisite: it had to hit the target...
At such a great distance, at such high speed, any slight deviation would result in an impact point vastly off target!
Luckily for Lynn, who was assisted by a smart brain, such level of computing power could not possibly lead to any mistakes!
Once everything was ready, Lynn raised his right hand and made a flicking motion. The hydrogen warhead turned into a brilliant streak of light amidst a piercing sonic boom, heading for the core of the Land of Death, the crater created by the last nuclear blast.
Its speed was Mach 25, seven kilometers a second!
Under the gaze of the citizens of Fire Oil City, the streak of light had barely appeared when it had already vanished from their sight, followed by the deafening sonic boom.
Only a group of Grand Wizards could barely make it out, but such a speed had already surpassed their reaction limits. Unless they moved out of the way in advance, or they were thousands of kilometers away, they were as good as dead the moment they were targeted.
And yet, such intense electromagnetic cannon was merely a tool for launching!
At twenty-five times the speed of sound, the hydrogen warhead, which originally had a silvery sheen, had turned red-hot. In just two seconds, the insulating layer on its surface had rapidly dissolved, and the heart of the Land of Death was already within reach!
The stored uranium-235 inside the hydrogen warhead exploded first, with thousands of neutrons starting to bombard the radioactive uranium, shattering it and then, in a chain reaction, producing more neutrons, continuously repeating this process...
