A few days later.

Castle Lord's Mansion Square.

Lu Chuan took out a small black iron ball, and the sword energy in his palm worked.

With the input of sword qi, a faint fluorescence gradually lingered on the iron ball, and thin lines were quickly lit up with transparent outlines, forming a formation, and the operation of sword qi was completed in an instant!

It's a formation!

After seeing the leather, Lu Chuan had a whim, although the power of the grenade bomb was good, it still lacked a little mobility, so he asked Li Fei's formation division to draw a starting device on the basis of the original grenade bomb.

As long as the user injects their own True Qi or True Yuan, they can activate the formation pattern and complete the detonation!

In Li Fei's surprised gaze, Lu Chuan held the iron ball and said, "City Lord, let's try our might!"

Li Fei nodded, and with a wave of his sleeves, two figures appeared in the field in an instant, each holding two figures in their hands.

Although these people's clothes were tattered, Lu Chuan could still see clearly that these were the people of the Northern Desert Army!

The bloody aura on their bodies was extremely strong, and even if they didn't have the True Qi running, it could be obvious.

Looking at the appearance, there are not a few lives in the hands of these two people!

Sure enough, in this instant, Li Fei's words came.

"These two are both captives of the Northern Desert, and there are not a few lives of the Great Xuan soldiers in their hands!"

The faint words echoed in the square, and Lu Chuan was silent.

Eyes swept over the field one by one, today's experiment, there are very few people in the field, most of them must be people Li Fei trusts, these people's faces are indifferent, hideous, and angry.....

But Lu Chuan knew that Li Fei was really saying this to him.

Lu Chuan took a look, and there were two of the Northern Desert captives with a deep aura, even if their clothes were tattered and covered in blood, each of them was pierced by two heavy barbs on their pipa bones.

Although the dantian was sealed, that temperament is still not so easy to change, except for these two, there is also a master of the three realms, two or three peaks of the second realm, and the others are all two realms.

Taking a deep breath, he stretched out his hand and threw the black iron ball at the group of captives, until he flew close to the captives, Lu Chuan's eyes lit up, and he shouted: "Explosion!"

"Boom!"

The extremely irritable gunpowder in the iron ball was originally triggered by Lu Chuan, resulting in an instant imbalance.

The furious power was ignited, and it burst open in an instant, and the terrifying explosion force blew a large crater out of a radius of several miles!

Flesh and blood flying!

There was even the roar of the captives!

After the dust and smoke passed, except for the two captives on the ground, the other captives had been blown to pieces!

And even so, even the flesh and blood in front of the two were blurred by the explosion, and one of the two arms was blown off, bleeding from the seven orifices, obviously suffering a lot of injuries.

The audience was in an uproar!

"This... This.... What kind of weapon is it that is so powerful!"

"Hahahaha, now those Northern Desert barbarians still dare to make bold claims to take down our Two Realms City!"

"God bless Daxuan!"

On the side, the craftsmen in the foundry also widened their eyes, and a big man with a tiger's back suddenly reached out and slapped himself, and after a while, Fang muttered: "This is really true!"

Li Fei and Lu Chuan glanced at each other, and both of them showed satisfied smiles.

But the woman in black standing behind her, at the moment of the explosion, her body also trembled, she had said before that these things were not necessarily useful, but in the blink of an eye, she was slapped in the face by Lu Chuan!

Bang bang!

Li Fei said with relief: "With this thing, we can take a big advantage, maybe we can fight to Luohe City this time." ”

The Luohe City that Li Fei mentioned was actually a city where the Northern Desert and Daxuan were handed over, and it was also under the territory of Daxuan before.

Since the invasion of the Northern Desert, Daxuan's defense line has been constantly retreating backwards, and the form is as dangerous as an egg, if the invasion of the Northern Desert is followed, the city of the two realms will fall, and within ten years, Lu Chuan may not be able to stop it.

After all, Da Xuan has always been a passive defense, every time the Northern Desert erupts, Da Xuan's defensive front will be pushed back thousands of miles, and now with Lu Chuan's proposal, the soldiers of the two realms can finally raise their eyebrows and fight a real counteroffensive!

"The power is indeed not small, the kid goes back and completes these bombs quickly, and then there will be a big battle!" Lu Chuan squinted his eyes at the ruins of the square, looking forward to it!

Ten days later.

Lu Chuan looked at the mountains of "grenade bombs" piled up in front of him, and finally breathed a sigh of relief, he basically didn't sleep for the past ten days, and even the sword qi in his body had been exhausted dozens of times, after these ten days of consumption, Lu Chuan's cultivation had been completely stabilized at the peak of the second realm!

However, the only regret is that the Tongxuan Sword is still in the casting process, and the piece of extraterrestrial meteorite iron is surprisingly difficult to melt, and although the strength has been steadily improved, it is useless.

Lu Chuan stretched out his hand and took out a short knife more than half an arm high, looking at the short knife.

Lu Chuan couldn't help but rub his hands excitedly, the whole short knife was brilliant silver, and there were hundreds of small hexagons on the outside, which was specially designed by Lu Chuan, these hexagons were like small flying knives.

These are all made of extraterrestrial meteorite, and after Lu Chuan returned, he handed over this piece of extraterrestrial meteorite to Li Fei and asked him to take it to the foundry and ask the master there to help.

As soon as the "bomb" came out, Li Fei couldn't wait for Lu Chuan to have a request, so he directly agreed with a wave of his hand, and asked the master of the foundry to create this short knife in strict accordance with Lu Chuan's requirements.

Looking at this short knife, Lu Chuan had to admit that professionalism is different!

Just looking at this short knife, it gave people an incomparably strong coercion, and Lu Chuan even invited the formation division of the City Lord's Mansion to take out a "Heaven Breaking Talisman" that they thought was the most perfect and engraved it on the knife body.

The inscription alone took them three days, and it was too difficult to engrave this level of material!

Even if it is a formation pattern master, the energy and true qi are a little unbearable, and after the knife body is inscribed, Lu Chuan will engrave these outer hexagons and let them engrave the sword qi arrays.

Lu Chuan even wanted to engrave a few more different formations, but since it was a knife, the sword qi formation pattern was naturally preferred.

Thinking about the hundreds of sword array runes, the sword qi that was triggered with the explosion of the sphere, just thinking about it made me excited!

Although there are no spirit stones and other materials to provide an energy source for the formation, Lu Chuan had a whim, and using the power of the rage to induce the sword formation pattern will also increase the power of the formation pattern to a certain extent.

This is all the result of Lu Chuan's repeated experiments with those formation pattern masters, and the inscription of the knife array runes must be very careful, and even those skilled masters have to be wary of the operation, because every time a formation is completed

Lines, all need to be set up with a weak silk thread to connect the core of the cutter body.

This knife is naturally prepared for Lin Lang, after all, he has never forgotten the promise between the two, and he will naturally give him a little surprise when the time comes!

Lu Chuan put away the short knife, walked out of the secret room, and said hello to Li Fei, all the assembly work has been completed, although he was prepared, he was still taken aback by Lu Chuan's assembly speed!

In less than a month, nearly 30,000 grenade bombs were assembled, which is nothing short of a miracle!

Li Fei asked Lu Chuan's opinion, and decided to gather all the forces of the Two Realms City, and half a month later, launch an attack on the Northern Desert army stationed outside the Two Realms!

After all, before the war, we need to adjust it, and we need to recuperate and recharge our strength, so that the soldiers of the two worlds are at their peak!

When Lu Chuan returned home, he found that there was no one, he went out for nearly half a month, and he didn't see Lin Hu, how can I say it, I still miss it a little in my heart!

Sin, sin!

"Childe!"

Before Lu Chuan could rest, Lin Hu rushed in from outside the door with an excited face.

What surprised Lu Chuan was that Lin Hu was already a powerhouse at the peak of the second order, and his breath was surging, like a heavenly knife out of its sheath, so that people didn't dare to look at it directly!

Lu Chuan patted Lin Hu on the shoulder, looking at this master who he had "cultivated" single-handedly, Lu Chuan couldn't help but be a little excited.

"Well done!"

"Hehe, this is all taught by Childe!" Lin Hu said with a smile.

Lu Chuan glanced at him a little angrily, "Give you three points of color, and you have opened a dyeing workshop!"

"What about the peak of the second realm, it's not that the master hasn't fought before!"

Lin Hu's expression was deflated, and he pouted, "Can I compare with you?"

Lu Chuan smiled, having said that, the movements in his hands were not slow, and he immediately reached out and took out the spirit stone in his arms, which he came from the City Lord's Mansion easily.

Without saying a word, he threw it directly to Lin Hu, Lin Hu was immediately overjoyed, with this spirit stone, his cultivation speed would go up to a new level again!

Broken Mirror naturally has a little certainty, if the extraterrestrial meteorite is bigger, he can still build a weapon for him, and this spirit stone will be regarded as compensation for him....

Lin Hu nodded, but did not speak, and the emotion in his eyes had already explained everything.

In his opinion, many words do not need to be said to be more flavorful!

"Childe, I heard that we are going to launch a general attack on the Northern Desert army?" Lin Hu said with some excitement.

Hearing him say this, Lu Chuan gave him a strange look, he had just told Li Fei about these things, how could he know so quickly?

But he didn't think much of it.

"Well, before I prepare to sneak attack the troops stationed in the Northern Desert this time, I want to try to see if I can help the Two Realms City solve a threat!" Lu Chuan nodded.

"Hehe, Childe, can I go to this sneak attack?" Lin Hu said a little bit of Ai Ai, obviously he wanted to go very much.

Lu Chuan frowned slightly, he didn't know why he always felt that Lin Hu had changed a lot since he came to the Two Realms City, and this feeling was becoming more and more obvious now.

Lin Hu was a little weak by Lu Chuan's gaze, scratched his head and sweated: "Or... Or... I'm not going?"

"What then. I suddenly remembered that I had something to do, so I left first!"
