There was a huge crater in the ground, debris of masonry flew everywhere, and the wall ten meters away was blown down in a large area, turning it into a pile of rubble.

Not only those craftsmen, but even the crabs at level 20, the old man at the eighth layer of vitality, and the pink who had just been promoted to level 25 were all stupid. None of them can stop this kind of power, and the protective qi can be torn to pieces.

"God, this is too exaggerated, isn't it! I can achieve such an effect with a full blow, but the lethality is definitely not so great, there are iron pieces everywhere, and it is estimated that a martial artist who is also an eighth-layer of Yuanqi will not be able to block such an explosion, and a demon beast of the ninth or twenty-sixth layer of Yuanqi may be able to block it......" The old man muttered to himself.

Jiang Xingchen didn't expect that after changing to an iron material, the power of the grenade would increase so much, and the killing radius was definitely more than fifteen meters, which was about the same as the power of the 60 mortar.

"Could it be that the iron has strong endurance, and after the Yuan Stone is broken, there is more energy accumulation inside the grenade...... Jiang Xingchen said secretly in his heart, this is the only possibility he can think of.

"Huh~" After a long time, the old man let out a long breath, a trace of decline appeared in his eyes, and he shook his head and said: "No wonder the Sixth Legion was killed and injured by an explosion, and even Wei Ning was almost shocked to death, this thing is too powerful...... With the appearance of such weapons, has the era of warriors passed......"

When the old man spoke, the crab also reacted, and hid behind Mei'er with his tail between his legs. The boss is terrible, if this thing is still on his body, he will definitely blow himself up.

Pink also chirped and burrowed into Mei'er's arms. Then he showed his little head and looked at Jiang Xingchen, his eyes full of horror.

"What are you afraid of?" Jiang Xingchen smiled angrily and lightly tapped his little pink head. said: "Your speed is so fast, I'm worried that this thing can blow you up!"

"Twitter!" Pink flapped her wings dissatisfiedly, knocked off Jiang Xingchen's fingers, tilted the bird's head and thought about it carefully, as if Jiang Xingchen was very reasonable, he was so fast, this thing couldn't blow himself up.

Gone are the fears. Pink immediately jumped out again, and her wings pointed at Jiang Xingchen and screamed. As if to say that your weapon is not a big deal!

Jiang Xingchen's words not only woke up Pink, but also woke up the old man.

"That's right. With my speed, I can definitely dodge this thing before it explodes!" As soon as the old man was excited, he immediately let out another breath, even if he could dodge. I am the eighth layer of vitality. Maybe the sixth layer of Yuan Qi can also dodge. But what about those below the sixth layer of Yuan Qi, and those in the realm of condensation. With the appearance of such a powerful weapon, who will practice martial arts in the future......

Jiang Xingchen silently walked to the master's side, gently hugged his shoulder, and asked, "Old man, why are you practicing martial arts?"

"Why?" the old man was stunned for a moment, and immediately said: "Of course, it is for the sake of military improvement, in this world." Only strong force can protect the family. in order to develop better!"

"Is this really the case?" Jiang Xingchen smiled and asked, "I don't have a cultivation, but if a martial artist with a first- or second-level vitality wants to kill me, he will definitely not be able to do it!"

"What do you want to say, boy?" asked the old man.

"Hehe!" Jiang Xingchen smiled and said, "In fact, the purpose of practicing martial arts is to maximize the development of the human body's potential, so that life can be longer and accumulate more experience and knowledge...... Martial arts training is not to improve martial arts and fight with others, but to fight with oneself and defeat oneself!"

Jiang Xingchen said, his hands behind his back, the gust of wind swept by, his clothes hunting, and he looked lonely.

But at this moment, the sky suddenly darkened, and a dark cloud obscured the sun.

"I'm the next Olympics!" Jiang Xingchen immediately stopped pretending, this is the rhythm of thunder and thunder! Besides, he didn't know what martial arts training was all about, and it was pure nonsense just now.

He didn't pretend, but the old man was surprisingly strict, hanging his head and pondering, as if he really had an understanding of Jiang Xingchen's words.

Even Mei'er frowned slightly, her eyes were stagnant, and her right hand unconsciously stroked the crab's neck, as if thinking about something.

Pink also quieted down, her little head tilted, her eyes solemn......

At this time, those craftsmen finally recovered from the huge shock, and broke out with a huge cheer, finally the development was successful, and the power was so huge, it was not impossible to keep the capital, and even defeat Xuanyuan Tianzong.

"Okay!" Jiang Xingchen waved his hand to greet everyone, now is not the time to celebrate, Xuanyuan Tianzong is less than two hundred miles away, at most tomorrow will be able to arrive, in the past two days, they must hurry up and produce, especially the trigger and delay device inside the grenade, Jiang Xingchen must do it himself, there is no machinery here, and only his precision curved array can complete such a precise work, no one else can.

"In two days, even if black and white don't stop, the production of 1,000 pieces will reach the sky...... But a thousand pieces should be enough, right?" Jiang Xingchen thought as he led those craftsmen quickly towards the workshop that had been prepared a long time ago......

At this time, the Moon Shadow Emperor was still restless, and the news from the front kept coming, all of which were about his own defeat, and the Xuanyuan Heavenly Sect was like a bamboo, constantly advancing, and now it was less than two hundred miles away from the Moon Shadow Capital.

And behind the capital, the 30,000 Praetorian Guards of the Qiankun Empire were still 800 miles away. They were blocked by Xuanyuan Tianzong's Fifth Heavy Armor Knights, and although they forced the other party to retreat again and again, the speed of the march was greatly slowed down, and it was obviously too late to come to the rescue.

"How is Jiang Xingchen's preparations?" the Moon Shadow Emperor asked loudly, now he pinned all his hopes on Jiang Xingchen.

"My subordinates are going to urge him again!" the head of the Hua family hurriedly replied, turned around and walked out.

At this time, the dean of the academy hurriedly ran in, walked to the emperor in two steps, and said with a breath: "Your Majesty, it's done, it's done!"

"What has become?" the emperor grabbed the dean's arm, feeling excited, and although he had already guessed the result, he couldn't help but ask.

"Jiang Xingchen's research has succeeded......" The courtyard lowered his voice.

Half a full month later, the emperor's order came from the palace: the gates of the Moon Shadow Capital City were closed. No one is allowed to go in or out, and the people must stay at home and not go out without a command.......

A barrage of orders went down. The entire moon shadow moved, and there were trotting soldiers everywhere, and the whole city seemed to be transformed into a military fortress in an instant.

The common people knew that war was finally coming. They all obeyed the order, hid in their homes, and secretly prayed: "I hope that the kingdom can be defended, and I hope that Xuanyuan Tianzong will retreat soon......"

Meanwhile. Less than two hundred miles away from the capital, the camp of Xuanyuan Tianzong was stationed here, with an army of 400,000. The barracks alone stretched fifty miles away.

In the big tent of the Chinese army, the great elder asked the sect master strangely: "Why don't we hurry up the march, if it is smooth, we can reach the capital in the middle of the night." The soldiers were resting. ”

The sect master smiled: "Don't worry. I need to leave plenty of time for the Qiankun Empire!"

"Huh?" The Great Elder was a little surprised, and couldn't help asking, "What does the Sect Master mean by this?"

"Do you remember what I said, I even thought of the Emperor Qiankun's posterior move...... He is not a soft-hearted person, and if my estimate is correct, he must want to abandon the Moon Shadow Capital, and take advantage of our attack to turn around and take those outlying towns, and besiege us in the Moon Shadow Kingdom. The sect master said lightly.

Hearing this, the Great Sect Master sneered: "Siege." Do they have the strength?"

"They think they have, and the ballista is indeed the nemesis of the heavy cavalry!" the Sect Master laughed as well.

The Great Elder said, "They would never have thought of it. We also have catapults, which are long-range attack weapons that can completely destroy their ballistas...... Hahahaha, I understand, the sect master wants to give them a chance to attack, occupy the moon shadow at the same time, and defeat part of the power of the Xuanyuan Heavenly Sect!"

The sect master narrowed his eyes and nodded: "That's what I mean, destroy part of their strength, their forces are stretched, and after the Moon Shadow occupies it, it will be able to stabilize for a while, just to consolidate the defense, and the transaction with overseas forces will be easier." ”

"The Sect Master has thought about it thoroughly, he must have already set up the catapult, right?" asked the Great Elder.

"This is natural! Ten catapults have been placed in each of the ten most important towns, which is enough to make them cry and cry for their mothers! And they would never have imagined that our camp looked like an army of 400,000 troops, but in fact only 200,000 people followed, and I had already arranged for the rest to wait for them in various towns...... Come on!" as soon as the sect master's voice fell, he called his subordinates, and then passed the order to go, the whole army should have more food, rest early, and the army would start early tomorrow morning.

The next morning, the sun was rising, and the army set out, killing the moon and shadow capital.

They were not in a hurry to move forward, and deliberately slowed down, so it was not until noon on the third day that they arrived at the Moon Shadow Capital.

The army stopped, and the Sect Master and the Great Elder rode to the front of the formation, looking at the huge Moon Shadow City Wall hundreds of meters away.

"Sect Master, how long do you think they can hold out?" the Great Elder asked with a smile.

"Hehe!" the Sect Master laughed and said, "How long they can hold out is entirely up to us!"

"Then why don't we talk to them first and see if the Moon Shadow Emperor will surrender?" the Great Elder asked again.

The sect master waved his hand and sneered: "There's nothing to talk about, it's a waste of energy! Moreover, if you take down the Moon Shadow so easily, I'm afraid the Qiankun Empire won't take the bait when it hears the news!"

The Great Elder said, "What the Sect Master said is that since this is the case, let them see the power of the catapult...... I can't wait to see it!"

The sect master didn't speak, but just waved his hand back, and two hundred huge catapults more than eight meters high were pushed out and slowly approached forward......

On the city wall, the soldiers of the Moon Shadow Kingdom were extremely nervous, they had never experienced war, and they felt terrified when they looked at the dense army in the distance, and they hugged the spears in their arms tightly one by one, as if they could find a little sense of security in this way.

But at this moment, a large row of large, strangely shaped objects came into their sight.

"What is this, why didn't they siege the city......." Moon Shadow's soldiers hid under the battlements of the city walls, looking at each other with puzzled expressions.

As if answering their questions, those huge monsters suddenly flew out of countless black spots, and almost in the blink of an eye, the chilling sound of breaking the air came into their ears, followed by a roar like thunder as if the end had come, shaking their eyes into darkness.
