If Heaven hadn't given birth to me, I would be arrogant.

The discovery of gunpowder truly delighted Zong Ze for a long time. To be honest, although the destructive power of gunpowder wasn't very high, that was in comparison to other types of gunpowder in that era. In reality, if gunpowder was used properly, its destructive power was terrifying!

Moreover, to be honest, Zong Ze finding gunpowder was really opportune for him. The instability of gunpowder was just right for him. If he had discovered TNT, a very stable gunpowder that requires a fuse or detonator to detonate, he really wouldn't have been able to make a fuse!

So, after a few days of simple testing, Zong Ze created an otherworldly version of the bomb. This bomb, sealed in an iron ball, did not need to be detonated; it could be easily dropped from a hot air balloon!

Zong Ze was genuinely excited after obtaining the bomb, but Xiao Hei's explanation quickly put an end to his idea of ​​equipping the Shenji Camp with bombs.

Xiao Hei told Zong Ze that the development of a world should be gradual. The development from cold weapons to firearms also happened step by step. If a world's technology develops too quickly, it will bring devastating consequences!

Only after Zongze pressed him repeatedly did he learn that gods, whether in the celestial realm or other realms, actually need the power of faith, and the source of the power of faith is ordinary humans in these different worlds. Therefore, in every world, there are all sorts of legends about gods!

The natural development of a world allows the gods to draw upon a continuous stream of faith power. Even as the world gradually develops into an era of technological progress, there will still be many religious followers.

For example, on Earth, although technological advancements have led some people to become atheists, many more people still hold faith, whether it be Christianity, Catholicism, Buddhism, Taoism, etc. The deities of these religions can still draw a great deal of faith power from humanity!

However, without this gradual development, if a world suddenly leaps from an era of technological backwardness to an era of technological progress for various reasons, it will inevitably lead to a large number of people no longer believing in gods!

For example, if Munenori were to use bombs on a large scale on the battlefield, enemy soldiers would find that their faith was not protected by the gods and would gradually lose their faith, and then try to obtain Munenori's bomb manufacturing technology to develop their own country!

When a deity receives no faith from a world, it is an extremely terrifying situation for that world. The deity might resort to extreme measures to destroy the world and revert it to a primitive state, allowing it to slowly develop again!

Xiao Hei also hinted to Zong Ze that many technological civilizations have been wiped out on Earth, but each time only the technology itself was destroyed; the myths and legends surrounding it never disappeared. For example, the Ice Age, and Noah's Ark, etc.!

Zongze finally understood some things, such as why the ancient Egyptians were able to build the pyramids, which even modern technology might not be able to build perfectly. Perhaps they were not built by the ancient Egyptians at all, but were left over from the previous civilization!

Of course, this doesn't mean that the bombs Zong Ze created were useless. Xiao Hei said that gods must exist in this world, but he couldn't say what level of god they were. However, Xiao Hei believed that as long as they weren't used in large-scale warfare, the occasional use of bombs wouldn't change humanity's beliefs!

After the bomb test was successful, the fire at the Shenji Camp was extinguished. A few days later, once the intense heat of the Shenji Camp had completely dissipated, Zong Ze led Zong Xiaozhang to the dark exterior of the Shenji Camp walls!

As they approached the Divine Machine Camp, even the Martial God Zong Xiaozhang exclaimed in amazement. The city wall, which appeared black from afar, actually shone brightly up close. When Zong Xiaozhang reached out and wiped away a patch of black ash from the city wall in front of him, he discovered that the city wall beneath the black ash was actually shining like a black gemstone!

Zong Ze pulled out a dagger from his pocket and tapped it against the city wall. Zong Xiaozhang was even more surprised, because he could tell that the sound of the dagger hitting the city wall was exactly the sound of metal clashing!

"Grandpa!" Just as Zong Xiaozhang was still in surprise, Zong Ze suddenly spoke up: "Why don't you use your weapon to strike this city wall with all your might and see if you can cause any damage?"

"Damaged?" Zong Xiaozhang finally understood why Zong Ze had dragged him here—he had him test the sturdiness of his Divine Machine Camp's city walls! However, Zong Xiaozhang wasn't angry; he just smiled and said...

"Xiao Ze! Your city wall is indeed very thick and sturdy, but don't forget that your grandfather is a warrior at the level of a martial god. Although I don't have the ability to break through your city wall in one go, I still have a chance to make a big hole if I attack continuously. After all, your city wall is only seven meters thick!"

"Hehe, Grandpa, that's why I asked you to try it!" Zong Ze also smiled: "Practice is the sole criterion for testing truth. Only after the experiment can I confirm the resilience of my city wall!"

"Alright!" Zong Xiaozhang didn't hesitate: "But I must warn you, Xiaoze, if I manage to damage your city walls in one fell swoop, don't blame your grandfather!"

"Go ahead and smash it! I won't blame you!" Zong Xiaozhang didn't realize that Zong Ze had unintentionally used the word "smash"!

"Alright!" Zong Xiaozhang immediately drew his battle sword, which had been with him for decades and had slain countless heads. It was a legendary item with a great reputation in the Holy Word Continent! As soon as Zong Xiaozhang shouted, Zong Ze felt a large amount of spiritual energy gather around him!

At this moment, the usually cheerful old man disappeared. Zong Ze seemed to see a tall and mighty warrior with boundless heroic spirit and murderous aura. The warrior's eyes were firm, as if no obstacle in front of him could stop the warrior's advance!

"Such a strong killing intent!" Little Black couldn't help but use his spiritual power to say to Zong Ze, "Junior Uncle, your grandfather has killed countless people in his life. This 'Slaughtering the World' technique is just too domineering. When you get it, remember to let me take a look first!"

"Huh?" Zong Ze was taken aback. Who was Xiao Hei? Don't be fooled by Zong Ze's constant bullying of Xiao Hei and his forcing Xiao Hei to call him "Uncle-Master." Zong Ze knew perfectly well that Xiao Hei was willing to be bullied and would only lower his head to call him "Uncle-Master" because of his cheap master and cheap senior brother!

Otherwise, try getting a Grand Luo Golden Immortal to call you Martial Uncle! You'd be lucky if they didn't just unleash a single immortal spell and strike you with Five Thunderbolts!
