Boom! Boom!
The entire earth trembled, roaring.
Everything was shaking. In an instant, Mingdu seemed to transform into a place where hell had descended, with an incomparable and terrifying explosive force that almost instantly caused the entire city of Mingdu to violently shake.
The intense shockwave almost swept across the entire city.
Countless debris and soil flew, and a vast amount of fragments soared, along with the scorching, frenzied, and terrifying shockwave that destroyed everything in the blink of an eye.
In that moment of explosion, the entire city of Mingdu was groaning, trembling, and collapsing in fear.
At the center of the explosion, the Cangshan area in Mingdu sank by more than a hundred meters.
Whether it was hundred-meter-high skyscrapers or ordinary residential buildings, they were instantly consumed by the explosion and collapsed in an instant.
"Ah! Tang Sect, I will never stop until we are both destroyed!" From several thousand meters in the sky, Yu Guanzhi roared to the heavens. Around him were three or four high-ranking officials from the Central Legion.
The explosion had come too suddenly, too terrifying. Even he, a Limit Douluo with a four-character battle armor, had only managed to save three or four high-ranking officials from the Central Legion.
But he had brought nearly the entire high-ranking staff of the Central Legion with him.
Now, they had all been wiped out in one fell swoop.
"Ah!" Heavenly Judge Douluo Lang Tian also screamed, dragging his broken body as he yelled. The police forces he had brought had been decimated, and only he had managed to escape.
The explosion had wiped out a third of the police forces in Mingdu instantly.
"Yu Guanzhi, what the hell was Ao Rui doing in the Tang Sect's underground armaments factory? The moment he entered, Xiao Ri detonated the underground armaments factory! Ao Rui was sent in by you! You bear an irreplaceable responsibility!" Lang Tian shouted at Yu Guanzhi, furious. After such a massive event, both he and Yu Guanzhi shared the responsibility. Lang Tian felt that he had already been ruined, and now he no longer cared about the differences in identity and strength between him and Yu Guanzhi.
Although Lang Tian had escaped into the sky and survived, the cost was that his red battle armor had been completely destroyed, and it couldn't be repaired. He himself had sustained injuries so severe that he would never recover in this lifetime.
Now, he had no time to care about the differences in status and power between him and Yu Guanzhi.
In other parts of Mingdu, strong individuals descended from the sky. Upon seeing the devastation of the Cangshan area, everyone's eyes turned red with rage.
This explosion's power even exceeded the one created by Ling Bing Douluo, Huo Yuhao, ten thousand years ago.
Ten thousand years ago, the explosion created by Ling Bing Douluo had primarily relied on the Level 9 fixed soul guide cannonballs stored in the underground of the Sun Moon Royal Soul Engineer Academy.
But that was ten thousand years ago.
At that time, the technology for manufacturing Level 9 fixed soul guide cannonballs wasn't yet mature. Even the Sun Moon Royal Soul Engineer Academy didn't possess more than twenty such cannonballs.
However, the Tang Sect's underground armaments factory's stock of Level 9 fixed soul guide cannonballs and other soul guide weapons far exceeded what the Sun Moon Royal Soul Engineer Academy's underground warehouse had at that time.
Now, the Tang Sect had fully mastered the technology to produce Level 9 fixed soul guide cannonballs, and it had even developed the capability to independently produce Level 10 fixed soul guide cannonballs.
As long as they had sufficient raw materials, the Tang Sect could continuously produce Level 9 fixed soul guide cannonballs.
The Tang Sect's underground armaments factory had been in operation for thousands of years. While most of the weapons produced had already been quietly sold to corners of the Douluo Continent, the accumulated power was still frightening.
A sudden explosion, and the consequences were unimaginable.
In fact, with the current defenses in Mingdu, if the explosion had originated outside of Mingdu and spread to the city, Mingdu's defense systems could have fully opened and completely blocked such an explosion.
But the problem was that this explosion happened inside Mingdu itself.
No matter how strong Mingdu's defense systems were, an internal explosion would render the defense systems almost useless.
What Yu Guanzhi didn't know was that there were three underground armaments factories in Mingdu, and one of them had already been discovered by the federal police. To increase the explosion's power, Xiao Ri had specifically concentrated the remaining stocks of the other two underground factories in this one.
Therefore, even though the explosion occurred at a depth of five hundred meters underground, the effects were devastating because the underground had already been hollowed out.
Even though this explosion only sank one district of Mingdu, it was still far more powerful than the explosion that had destroyed a third of the city ten thousand years ago.
In reality, after ten thousand years of development, the area of Mingdu was now more than ten times the size of what it was back then.
Now, a single district like Cangshan had a population of several million.
Fortunately, although the current population of Mingdu far exceeded that of the city ten thousand years ago, it no longer had the All-Continent Senior Soul Master Elite Tournament, so the population density was somewhat lower than it had been back then.
Otherwise, the consequences would have been even more unimaginable.
All of this had naturally been calculated by Xiao Ri.
What Xiao Ri wanted was to use this explosion to warn the Sun Moon Federation: "Leave a way out for the Tang Sect, and we can meet again in the future."
The Tang Sect had been around for 20,000 years.
If the Sun Moon Federation didn't leave a way for the Tang Sect to survive, then the Tang Sect's counterattack would be something the Sun Moon Federation could not withstand.
The Royal Academy district's underground armaments factory had already been sealed by the federal police. With the capabilities of the Sun Moon Federation's police and military, even if Xiao Yicai didn't reveal anything, the military and police would eventually find the other two underground armaments factories through investigation.
Then, they would gradually search other cities. As long as they used the most precise underground scanning equipment, although it would be costly, the Sun Moon Federation would eventually uncover all of the Tang Sect's underground armaments factories.
Heartless Douluo Cao Dezhi was under house arrest in the Blood God Legion, and Affectionate Douluo Zang Xin's whereabouts were unknown.
Now, the Tang Sect was leaderless. Faced with this situation, Xiao Ri had no good solutions. To protect the Tang Sect's foundations, he chose the most extreme but effective method.
He believed this would surely intimidate the Sun Moon Federation.
"Tang Sect! You claim to be just, yet you've done such a horrifying thing!" Yu Guanzhi's eyes were red with fury, and terrifying soul power burst from his body. He ignored Lang Tian's furious shouting at him, his gaze fixed firmly on the center of the explosion.
As the leader of the Central Legion, a Limit Douluo with a four-character battle armor, in that moment, he had no idea what to do next.
The Tang Sect had done such a horrifying thing?
The Sun Moon Federation would undoubtedly hold them accountable.
But if they kept investigating further, who would bear the consequences?
Let's not forget, the Tang Sect still had sixteen Level 1 armaments factories.
If these factories also chose to go down in a blaze of glory, then the Sun Moon Federation would truly be finished.
Everything was unfolding just as Xiao Ri had predicted.
This explosion had successfully intimidated the Sun Moon Federation.
Or rather, it had shaken them!
