"A-Yao really said that?"

"Hmm. ”

Zhuge Heng nodded: "Your Highness may not know yet, this demon king-level demon spirit stone is too precious, even if it is the strongest Tianji Sect on the mainland, we only have 11 demon king-level demon spirit stones, the eldest lady opened her mouth this time, and asked for 8 in one go, saying that she needed it for her own cultivation, but in fact, she only left one, and the rest was sent to His Highness." ”

"A-Yao is so caring......" Lin Muyu couldn't help laughing.

Zhuge Heng also smiled: "With the words of His Royal Highness Yu, the eldest lady's hard work has not been in vain, and her subordinates will truthfully tell her, besides, does Your Highness have anything else you want me to tell the eldest lady?"

"How many troops does the Bai Ze Mercenary Group have?"

"Of the 100,000 people, Miss Sikong Yao borrowed twenty commanders from General Zhang Sheng to help train the troops, and the combat power of the Bai Ze mercenary group has reached a considerable level. ”

"Can you borrow the general's?"

"That is, General Zhang Sheng is the grandfather of Miss Shang Qian, and Miss Shang Qian personally went to say how it was possible not to borrow it in the future. ”

"These generals will be returned as soon as they are used up, and they will not be kept. Lin Muyu said.

"Yes. Zhuge Heng was also an old fox, and said with a smile: "Sooner or later, Bai Ze's mercenaries will have a battle with Zhang Sheng's legion, and the enemy's people will naturally not be able to stay." ”

"Haha, that's right, come here, transport goods, and return to Winter Frost City overnight!"

"Yes!"

......

galloped in the starry night, and returned to the Eastern Capital Winter Frost City at noon the next day, Lin Muyu did not sleep, and personally sent twenty carts of Demon Heart Stones to the Weapons Division to find Qin Ziling.

After Qin Ziling saw so many Demon Heart Stones, he was so happy that he almost danced with his hands: "Your Highness, where did you get so many Demon Heart Stones, it's great...... Great!"

"I have a secret channel, Ziling doesn't have to worry about it, by the way, what are you doing these days?"

"Your Highness, follow me and see. ”

"Oh?"

Lin Muyu and Wei Qiu, Situ Sen, and Situ Xue looked at each other and smiled, and then followed Qin Ziling with the generals into the large school field in the backyard of the Ordnance Division, and there was a clanging sound in the distance, and I don't know what was being cast, but this is the secret base of the Great Qin Empire, Lin Muyu knows that the development of the Ordnance Division is related to the fate of the entire Great Qin Empire, and rejuvenate the country with science and technology!

A short distance ahead, there is the shooting experiment base of the arrow box, and a group of weapons department staff are busy loading arrows, and then shooting at the rocks in front of them. In the sound of "dangdang", one arrow after another sank into the rock, leaving only Ling Yu still outside.

"It is the hardest stone in Lingdong Province, called Cockscomb Stone. Qin Ziling said with a smile: "I have improved the torque device of the arrow box, which greatly increases the shooting speed, and these arrows are the dual elements of refining the Demon Heart Stone and the White Diamond, and the lethality is doubled, General Sen should also know the principle of shooting, right?"

Situ Sen nodded: "I know a little bit about Dragon Dou Xuan. ”

"That's right. ”

Qin Ziling said: "Although my cultivation is low, I also know that the Dragon Douxuan is an energy field similar to a whirlwind, and the power of the Dragon Douxuan is similar to a wicker rotating on an axis, and the speed is very fast, so that relying on the centrifugal power and dragon crystal on the periphery can resist the bombardment of the magic crystal cannon, and even withstand multiple bombardments in a row to ensure that it is safe, so I focus on improving the shooting speed of the arrows, as long as the arrows can be sent into the gaps in the air flow of the Douxuan." ”

Lin Muyu was silent.

"Your Highness, what do you think?" Qin Ziling said.

"No, I can't. ”

Lin Muyu shook his head: "I have fought with the dragon knight many times, and I know the circulation speed of the Dragon Dou Xuan, even if Ziling you have improved the shooting speed of the arrow box, but it is still far from keeping up, the speed limit of the torque device is almost destined to be unable to keep up with the Dragon Dou Xuan, I can give you an exact number, in the field of the Dragon Imperial Dou Xuan, at the same point, at least fifteen Dou Xuan air currents pass through in one second, and ordinary quivers may not be able to catch up with such a speed in a lifetime." ”

"Oh my God, ...... so fast" Qin Ziling was stunned, the whole person became a little depressed, and the idea of working hard for half a month was reduced to a bubble just because of Lin Muyu's words, and this blow was too big.

On the drawings on the side, the hand-painted operating principle of the dragon and the dragon whirl, the dragon and the dragon knight are lifelike, Lin Muyu reversed several drawings in a row, and had to marvel at Qin Ziling's conscientiousness, but unfortunately, the degree of development of science and technology is far from enough, because of the lack of gunpowder, so it lacks the most fundamental driving force, if the arrow can reach the flight speed of the bullet, it is possible to cause a certain lethality to the god-level dragon knight.

"Gunpowder, gunpowder...... He couldn't help but sigh secretly, could this be that God was torturing himself?

"What is gunpowder?" Qin Ziling was stunned.

"It's nothing ......" Lin Muyu leaned on the table, thought for a while, and said: "Gunpowder is a product of another plane, once it explodes, it will produce a huge airflow impact, so that the artifact can obtain an unimaginable speed, if we have gunpowder, push the Demon Heart Arrow to shoot, it should be able to achieve unexpected effects." ”

"The impetus of the gunpowder explosion?"

Qin Ziling stood blankly in place, suddenly slapped his thigh, and laughed: "Thank you, Your Highness, for the reminder, hahaha, great...... Thank you, Your Highness, for the reminder!"

Lin Muyu looked at him in amazement: "Ziling, what are you doing, it's like winning the Mark Six lottery." ”

Qin Ziling was so excited that his whole body trembled, and he said with unkempt eyes: "It was Your Highness who reminded me that the airflow generated by the explosion can greatly increase the speed, and maybe you can break through the speed limit and destroy the defense of the Dragon Imperial Douxuan." ”

"So what?"

"Your Highness, have you forgotten the amazing power generated when the Demon Crystal Cannon explodes, what if we cast the arrow cluster of the Demon Heart Arrow into the periphery of the Demon Crystal Cannon, and then use the power generated by the explosion of the Demon Crystal Cannon to send the Demon Heart Arrow to break the Dragon Imperial Dou Xuan?"

"Really?" Lin Muyu was shocked.

"Yes, at least we can try!"

Qin Ziling laughed excitedly, and Lin Muyu also laughed, as if he had seen the dawn.

On the side, Wei Qiu poured cold water: "Your Highness, Lord Ziling, don't forget how high the temperature generated by the explosion of the magic crystal cannon, when the demon clan was in the war, their armor demons were wearing heavy armor, and there was not even a little bit of slag left under a magic crystal cannon, not to mention the small arrow cluster of the demon heart arrow?"

Lin Muyu was stunned: "It's also right ......"

Qin Ziling hadn't calmed down from the excitement yet, his head was covered with sweat, and he said, "It's okay, we just need to find some substances that can withstand high temperatures to fuse and refine the Demon Heart Stone." ”

"But how could a substance that could withstand the high temperature of the Demon Crystal Cannon melt the Quenching Demon Heart Stone?" Wei Qiu said.

"Ah......h

Qin Ziling was stunned for a moment, and then stretched out his hand and pointed to the gate of the Weapons Division: "Wei Guogong, you go out, you are not welcome here......"

Lin Muyu laughed and patted Qin Ziling's shoulder: "Don't worry, think slowly, there will always be a way." ”

"Hmm. ”

Qin Ziling nodded and said, "Please rest assured, Your Highness, Ziling will definitely think of a suitable way to cast this divine weapon to help my Qin family turn things around." ”

"Well, it's up to you, then we won't bother, Ziling, you have to remember to eat on time, you're all emaciated, did you use a few demon beauties as concubines a few days ago?"

"I didn't ...... Haven't ...... yet."

......

In the middle of the night, Lin Muyu once again tempered a demon king-level demon spirit stone, since he cultivated the elephant formless technique, his body was like a dry well, longing for the moisturization of spiritual power, and it was strange to say, the sea of qi seemed to be widened a lot by the elephant formless technique, and it was bottomless, even the demon king-level demon spirit stone could absorb at least eighty percent of the power.

"Hoo ......"

With a gentle breath, the demon spirit stone had completely disappeared from the palm of his hand, and the turbidity was scattered in the room along the mouth and nose, just after being completely refined, Lin Muyu only felt that his blood was boiling and rolling, which made him very excited, could it be that he was about to break through again?!

This elephant invisible trick simply makes him like a god, and I am afraid that there are few people in the Three Realms with such a breakthrough speed, right?

began to gather the divine power in his body, and hit the Qi Sea Entrance again and again.

The first thirty waves were very easy, until the thirty-first was a little difficult, but he was still able to control it, and in a blink of an eye, he had broken through the thirty-six waves, and he continued to gather all his divine power together without hesitation, and frantically hit the entrance of the entrance, "poof", the entrance was broken!

There was a sharp pain in his body, but Lin Muyu still maintained the clarity of the spiritual platform, he had already broken through the thirty-seven cave heavens at this moment just now, but he felt that there was still some potential left in his body, and he could continue to excite it!

A crazy thought flashed through his mind, breaking through the double realm in one fell swoop!

The thirty-eighth wave surged wildly, and began to impact the thirty-eight Heavenly Entrances that had just been concluded, and the glossy Entrances began to twist under the crazy impact, and the pain caused by them was naturally not something ordinary people could bear.

Lin Muyu spit out a mouthful of blood with a whimper, and the power in his body flowed out like a river, and the power of the Binding God Lock, Qiyao Immortal Hu, and Dragon Blood Battle Shield quickly came out of his body, buzzing with light, this is going to go crazy?!

He was slightly stunned, his brain domain had begun to blur, and sure enough, his cultivation could not be radical!

At this moment, Lin Muyu has begun to regret a little, but what's the use of regretting?

"Red Crystal Dragon!"

A roaring call from the depths of the soul instantly tore open the plane behind him, and the red crystal dragon rushed out with a bright dragon groan, turning into dragon armor and wrapping around Lin Muyu, and at the same time, the dragon power formed a shield to protect the master's divine power from leaking out.
