"Boom~~~~" When the deafening sound came out, many people were so shocked that they couldn't speak, especially those who belonged to the 'Hidden Dragon Society', who were even more stunned.

Three hundred smoothbore guns, although it is only the most primitive kind of front-loading version, the speed of each bombardment is not fast, but for the first time to see such a scale and how to attack, almost all are scared to pee!

What made everyone feel even more terrifying was the ...... of the bombardment

After careful calculation, the shells used this time were 'Thunderbolt' and 'Fierce Breaking Bomb', and the target of the direct bombardment was the seemingly impassable tall city wall!

The result?!

After the 300 smoothbore guns bombarded ten times in unison, people can clearly see that there has been a big gap in the position bombarded by those artillery, and the effect is obvious.

"Why don't you fight?!" Zhang Ling stopped after seeing those strange and powerful weapons after ten rounds of attacks, and asked Hua Wujian suspiciously.

"I forgot to say it clearly. Hua Wujian smiled and said to Zhang Ling, "Although this 'Destroyer' is powerful, it can't attack for a long time, and after every ten attacks, you need to stop and let it cool down, otherwise there will be problems." ”

"Cool down?!" Zhang Ling nodded thoughtfully when he saw that those who were responsible for using the 'Destroyer' had splashed it with prepared water.

Zhang Ling, who thought that he knew the characteristics of the other party's magical weapon, knew that all this was just what Gu Yi and Gu Yi made.

In the previous life, it was not clear how many shells those primitive smoothbore cannons on the earth could last, but in the Zijin Continent, the limit of these shells was actually close to forty shells and it was guaranteed that there would be no accidents!

Of course, due to the fact that the hot barrel is still dangerous, after thirty shells, it is better to use solid or solid scattered shells without any additives!

In the face of an enemy who was almost like a turtle cowering and defending, Hua Wuqian didn't need to discuss anything with Gu Yi, and formulated a strategy that could not only hit the enemy, but also confuse the temporary allies!

Everything has advantages and disadvantages, and there are weaknesses that are difficult to make up.

Like the 'Destroyer' they are using now, the biggest weakness is that it is too cumbersome, extremely difficult to transport, and when using it, it needs to be set up in a good position, and it cannot be quickly transferred, etc.

However, these problems are not too big for the time being, and can be solved temporarily as long as the logistics are stable and adequate protection is ensured. An enemy like Luo Fei's now, who had never considered counterattacking almost from the beginning, had no way to deal with it!

In this way, it is easy to make a terrible impression with a temporary ally: the 'Hidden Dragon Society', causing the opponent to be too guarded.

As a result, Hua Wuqian formulated from the very beginning to deliberately create and magnify the shortcomings of the 'Destroyer' to confuse others.

First of all, the usable time has been greatly shortened! Although the power is extremely great, only ten attacks can be regarded as within the range of Zhang Ling's psychological acceptance. According to the speed of those warriors used, ten attacks were only a quarter of an hour, and as long as they survived this quarter of an hour, there would be enough time to recover.

"How long does this take to rest?!" Zhang Ling asked as she saw the warriors who were splashing water, constantly wiping all parts of the strange weapon, and pretending to be curious.

"At least half an hour, we need the Destroyer to cool down completely!" Hua Wujian said with a regretful look, "Otherwise, we won't be able to hit the next ten rounds!"

"Oh!" Zhang Ling nodded thoughtfully, her eyes flashing with an inexplicable light.

"Brother Hua, the other party is holding back, we don't need to take it down once, it would be better if we played one round every day!" Zhang Wuji smiled on the side and said, "This 'destroyer' is extremely powerful, and the momentum is earth-shattering, it won't take a few days, those people will collapse!

"Brother Zhang is really high!" Hua Wujian nodded with a smile, "I also think about it in the next place, after today's round, it will be bombarded again tomorrow, it won't take ten days, and this seemingly insurmountable continuous city wall in front of you can be easily taken!"

"Haha, the hero sees the same thing!" Zhang Wuji laughed, pulled Zhang Ling and continued, "Then Zhang will go back to rest." But Brother Hua, this 'destroyer' seems to be cumbersome, and I'm afraid the position can't be moved at will, right?"

"Not bad!" Hua Wujian was stunned for a moment, then nodded and said, "It's just that as soon as I saw it, Brother Zhang saw its disadvantages, and he really deserved to be handsome!"

"Brother Hua has won the award!" Zhang Wuji glanced at Zhang Ling and Ao Chunyi beside him, and said modestly.

"Don't hide it from Brother Zhang, this 'destroyer' is very good, but it is too cumbersome!" Hua Wujian pretended to regret and sighed, "To transport these big guys, it requires several times more manpower than ordinary materials! There are also those ammunition it uses, the solid ones are bulky and difficult to transport, and those that have other uses are very dangerous......"

"Then Brother Hua has to protect them well!" Zhang Wuji nodded with a smile, and then said, "It's better to go down and rest first!"

"Please!" Hana nodded and watched the other party leave.

"Husband. Yin Xue Niang, who had been standing aside and had seen and heard everything the whole time, walked up to Hua Wujian and said, "Will they be fooled?"

Although Yin Xue Niang is Hua Wuji's wife and a person of great power under Gu Yi, due to her background, she did not tell the secrets of those lurkers. So Yin Xueniang didn't know Zhang Wuji's true identity, so naturally she didn't know Ao Chunyi's identity!

She just thought that Hua Wuji's words were an inducement for everyone.

"It doesn't matter if they believe it or not!" Hua Wujian smiled and said indifferently, "Anyway, we did this, how do they know the depth?!!" But with Zhang Wuji's thoughts, I guess he should know that I have something to hide, but I don't know how much I have hidden!"

"That's right. Hua Wujian looked at his wife and said solemnly, "Those 'Destroyers' must be protected, and all those responsible for using the 'Destroyers' must also be protected!"

"Yes. Yin Xue Niang nodded, and went down to arrange everything.

"Brother Mowgli. After returning to her big tent, Zhang Ling couldn't help but say to Zhang Wuji, "That 'destroyer', what are you going to do?!"

"What should I do?!" Zhang Wuji sat in his place, looked at Zhang Ling and said softly, "Let's not say that we are still allies at the moment, I am afraid that it will destroy this alliance, it is really unwise! Even if you don't worry about this, do you think Hua Wujian will not take precautions?!"

"Now that the people of the Luo clan can't shrink down, even if they have an idea of what the 'destroyer' is, it will take a day or two to prepare. At this moment, all the precautions to deal with can only be our ally!" Zhang Wuji sighed and said solemnly, "All of us know that the alliance is only temporary, and there will be a battle between us in the future! Hua Wujian dares to take out the so-called 'destroyer', and he must have his confidence! Presumably, at this moment, the position where the 'destroyer' is located and those who use it are well protected!"

"Then we won't do anything?!" Zhang Ling said with some annoyance, "That 'Destroyer' is terrible......"

"Marshal. Ao Chunyi stood up at this time and raised his doubts, "The weakness of the 'Destroyer' is really as Hua Wuqian said?"

"Little Hou Ye really has some doubts!" Zhang Wuji looked at Ao Chunyi, and said with appreciation and agreement, "What Hua Wujian said is not true, I'm afraid it is exaggerated and concealed!"

"What?!" Zhang Ling didn't expect this, and immediately looked at Zhang Wuji and said, "Brother Wuji, you said that the situation of the 'Destroyer' is not true?"

"Judging from my observations, the 'Destroyer' should be made of steel with unknown proportions, and judging from its size, it should be very cumbersome, and it will indeed be more troublesome to transport and transfer!

"What the marshal said is exactly what Ben Hou thought!" Ao Chunyi didn't have any expression on his face, but he was already smiling in his heart.

As Gu Yi's eldest son, Ao Chunyi actually knows some basic information about this 'destroyer', presumably although Zhang Wuji doesn't know it specifically, he also has some understanding.

In the conversation just now, the two of them conveyed one of the biggest misinformations: the 'Destroyer' is made of steel alloys!

The Purple Gold Continent is a crooked-necked world of technology, and because of the need for sharp and sturdy weapons, the alloy technology can be called exquisite! Even the technology of the Earth where Gu Yi was located in his previous life was not so powerful!

However, to make the 'Destroyer', that is, the cannon, the cannon body does not need too tough metal, but mainly softer metal, that is: copper!

Don't look at the metal copper, due to its characteristics, it has long been eliminated from the scope of the main metal used in the Purple Gold Continent, even the barbarians, orcs and half-orcs with poor smelting technology have given up becoming the main metal, but it is the most important metal material for making cannons!

Gu Yi clearly remembered that whether it was the relatively backward martial arts world in the previous life or the scientific and technological world where artillery on the earth had developed to an extremely high height, copper was still the most important metal material for the manufacture of cannons!

Gu Yi doesn't remember the specific principle, after all, his focus is not on this aspect, but he remembers that he deeply remembers this in some books and film and television works.

Therefore, in the later research on artillery in 'Xiao Heaven', Gu Yi also put forward this point of view, and it was confirmed by the research team!

Compared with other alloys, copper alloy is indeed too soft and not a good weapon material, so even if the copper ore in the Zijin Continent is very rich and easy to mine and smelt, it is not valued by everyone.

In addition to being used on general things such as household utensils, I am afraid that only some small items will be used on the battlefield (such as stirrups, etc.). ）

According to normal people's thinking, the stronger the cannon body of the 'Destroyer', the better, but they know that the ductility of copper is its greatest role in becoming a cannon barrel!

So in the conversation between Zhang Wuji and Ao Chunyi, they misled this information through the observer Zhang Ling, thus affecting the speculation and research of the 'Destroyer' of the 'Hidden Dragon Society'!

"Marshal, what do you think Hua Wuqian said, that it can only fire ten rounds and takes half an hour......"

"From Hua Wuji's final words, it will be at least half discounted!" Zhang Wuji interrupted Ao Chunyi with a smile and said, "Hua Wuji said that it can only fire ten rounds, and in my guess, it will be at least half discounted! That is, at least twenty rounds!"

"As for the statement that you need to rest for half an hour...... Zhang Wuji frowned and said in a speculative tone, "It may be the cooldown time after its extreme use!" I can't judge this, but what is certain is that if it is only ten attacks, it will not take that long!"

"Your Majesty must be informed at this time!" Ao Chunyi immediately spoke.

"That's good!" Zhang Wuji nodded, and said solemnly, "The three of us all write information and report it to Your Majesty, and write down what we see and think!"

"Yes!" Zhang Ling and Ao Chunyi glanced at each other, then nodded and said.

Zhang Wuji's words sounded very simple, but he vaguely pointed out a fact that they all guessed: Empress Zhao Min had installed people in their army!

This is something that everyone knows and understands!

After all, it is impossible to go out without a little checks and balances and surveillance! Unless he is like Gu Yi and personally sits on the front line, it is a logical thing to arrange for some people to spy on him in secret!

Zhang Wuji's meaning is very clear, since he wants to be on the throne, he must be frank and open, and don't be caught by those who are spying on him!

After all, compared to Zhang Wuji and other people on the surface, they have only one task: to monitor and find faults!

Although Empress Zhao Min can see what the truth is and what is nitpicky, after all, it is better not to leave anything behind!

At the same time, Zhang Wuji also returned to Gu Yi's big tent and reported the situation.

"Good job!" Gu Yi smiled, not caring at all about Hua Wuqian using tricks to induce without reporting.

He is not the kind of person who has to hold everything in his hands, and he knows how important it is to delegate authority to his subordinates! If he has to decide everything by himself, what do he need his subordinates to do?!

What's more, Gu Yi also knows that Hua Wuji's subtlety and intention of this plan must be smooth.

"Giggle......" Gu Yunniang said with a coquettish smile, "I guess after knowing this information, our Empress Majesty is going to be in a hurry, right?"

"It's not just her who is anxious!" Blue Phoenix interjected with a smile, "Then Luo Fei will definitely be anxious too!

As Blue Phoenix and Gu Yunniang said, when the information of the 'Destroyer' was transmitted back, Zhao Min and Luo Fei were shocked and gave orders one after another!

This attack, which changed the way the Purple Gold Continent operated, was destined to leave a mark in the history of the Purple Gold Continent!
