"But yesterday you bombarded the walls with gunpowder, and the whole ground shook with it, and it felt almost like an earthquake, and I wondered if it was an earthquake warning from above, or if there was something like gunpowder underground." Li Shimin took a deep breath and said.

Since ancient times, people have called the incomprehensible phenomenon the meaning of heaven, but since Merton's appearance has been repeatedly cracked and overcome, Li Shimin naturally found Merton's head.

Merton suddenly realized, only then did he understand what Li Shimin meant, since all kinds of natural disasters were overcome, coupled with the cracking of the Tengu Eclipse Day, the only thing that could restrain the imperial power was the earthquake, plus Li Shimin felt the same feeling as the earthquake yesterday, and he naturally became suspicious in his heart.

Merton suddenly fell into a dilemma, he naturally knew the principle of the earthquake, but the earthquake occurred on the surface, and even future generations could not predict it, let alone the technology of the Tang Dynasty, Merton knew and could not confirm it.

And once he said the principle of the earthquake, the imperial power lost its last restraint and became a power monster, he couldn't predict it at all, and of course the consequences of deceiving Li Shimin were equally serious.

Li Shimin did not urge, but waited quietly.

Morton gritted his teeth and stepped forward and said: "The earthquake is hidden deep underground, unpredictable, and unverifiable, although the Mo family has a record, but it is just a guess, this result is that the sages of the Mo family themselves can't believe it, let alone some ordinary masters." ”

The earthquake is not like a lunar eclipse and a solar eclipse, although it is far away, but it can also be observed with the naked eye, but the earthquake occurred underground, there is no way to guess, Merton first took a preventive shot, so as not to disappoint Li Shimin.

Li Shimin said in a deep voice: "But it doesn't hurt to say, I just want an explanation." ”

Merton nodded and said: "The Mo family is based on mechanics, what happens to earthquakes, landslides and ground cracks, mountains and rivers break off, houses collapse, strong earthquakes are thousands of miles away, you should feel shaking, how can this not be a kind of force?" It's just that this kind of force is too huge, far beyond the imagination of ordinary people. ”

Li Shimin nodded, it is this kind of power that is too huge to make people awe-inspired, and it is called the will of God.

Mozi Tianzhi said: "The Son of Heaven is good, and God can reward him; The Son of Heaven is violent, and Heaven can punish him. "Even if you are the Son of Heaven, Heaven can reward and punish, and the means of Heaven to reward and punish earthquake is one of the most serious.

"Such an earth-shattering power, how can it be done by manpower, but after the kid used gunpowder, he vaguely guessed." Merton said in a streak.

Li Shimin's face suddenly turned grim, and he stared at Merton.

"The kid believes that earthquakes are not a celestial will, and are just as natural as tengu eclipse days." Merton affirmed.

"What basis do you have?" Li Shimin said hoarsely.

Merton thought for a moment and analyzed: "First of all, earthquakes mostly occur in mountainous areas, and they are distributed very regularly, if Your Majesty lists the locations where earthquakes have occurred recorded in all dynasties, you will find that the places where earthquakes occur are like a belt, and there are almost few in other areas. Or not at all. ”

Li Shimin's heart moved, if this is the case, I am afraid there will be a big problem.

Merton said again: "Besides, if it is really a punishment from God, then why doesn't God directly punish Chang'an, or the surrounding places, isn't this kind of punishment the most effective, but most of the earthquakes are thousands of miles away." ”

Li Shimin nodded, this is indeed a suspicious point.

"According to the Mo family's speculation, what caused the earthquake? Could it be that there are minerals buried in the ground that resemble gunpowder? Li Shimin asked solemnly, the ingredients of gunpowder, sulfur and saltpeter, are all minerals, no wonder Li Shimin would guess so.

Merton shook his head and said: "Naturally not, when the Mo family observes that when earthquakes occur, they often cause cracks in the ground, so it can be inferred that the cause of the earthquake is likely to be caused by the fracture of the rock layer underground."

"A fracture of a rock layer can cause an earthquake." Li Shimin frowned and said, this reason is too simple, which makes him a little difficult to accept.

Merton nodded, looked around, and suddenly saw a familiar potted plant, and an arrow stepped forward to pull it down.

Li Shimin's cheeks twitched, this potted plant was the one that survived when Merton demonstrated the management of the Yellow River, but in the end it did not escape Merton's poisonous hands.

Merton reached out to remove the branch of the potted plant, picked up the main stem, held it with both hands, and suddenly forced, and the main stem of the potted plant broke in the middle with an instant.

"Your Majesty, look, this is the force that occurs when it breaks." Merton handed the broken half-bonsai trunk to Li Shimin.

"That's the cause of the earthquake!" Li Shimin looked at Merton with an unkind face, this kid destroyed his most beloved potted plant, but gave him such an answer.

Merton said without shame: "Yes, the force of a broken branch is naturally very small, but if a person's hand is placed on the broken place, it can still feel pain, but what if the trunk of a tree is broken by a person?" ”

Li Shimin's heart was awe-inspiring, that kind of strength might be able to kill a person.

"According to the Mo family's investigation, there are rocks under the soil, and Your Majesty will try to imagine the following, if the rock is a few miles thick or even more than ten miles thick, how much force will it produce." Merton said excitedly.

Li Shimin's eyes lit up suddenly, this time he believed Merton's statement, in addition to the soil under the ground, there are stones, maybe this is the only explanation that can answer the cause of the earthquake!

"It turns out that there is really no Tianzhi." Li Shimin suddenly rejoiced, his heart was like a big stone being moved, and he suddenly came refreshed.

Merton suddenly sighed: "Of course, this kind of speculation is impossible to verify, after all, the earthquake is underground, not to mention that you don't know where the earthquake will happen, even after the earthquake, it is impossible to go deep to confirm it." ”

Li Shimin's face suddenly darkened, although he had broken the sense of heaven and man, but he also knew that he said to Merton that even if he said this set of theories as it was, it would be impossible for those old stubborns to accept it.

The secret of the Tengu Eclipse Day can only be seen in the light of day on the first day of May, but the spread of earthquakes may be a long way off.

"Okay, stand down! Don't talk to anyone about today's events. Li Shimin looked at the map and said coldly.

The most important thing in Datang now is the Western Expedition, before the Western Expedition is over, there can be no negligence, Li Shimin doesn't want to have a fire in the backyard at this time.

"The minister understands!" Merton nodded, and bowed back.

After Morton retreated, Li Shimin clapped his hands, and Pang De instantly walked in from outside the hall.

"What does Your Majesty command?" Pound Road.

Li Shimin said: "The King of Wei once told me that he wanted to write a book of mountains and rivers geography to correct the name of my Tang Mountains, which is really a piece of loyalty. ”

Merton never imagined that the famous Kuodi Chronicles of Li Tai in later generations would be born ahead of schedule because of him.
