The strength of the southern general Xiao Gui is a third-order martial marquis, and there are a total of five armies under his command, and the commander of each army is a first-order martial marquis strength. Each army is divided into 10 detachments, and the captains of the detachments are all middle- and high-level military generals, just like Ma Keng. In the 5th detachment, in addition to Ma Keng, there are 10 generals in charge of 10 squads. The strength of the rest of the soldiers was 181 martial arts, 753 martial artists, and 56 samurai.

"That is to say, 99% of our 5th detachment is below the strength of military generals, and they can't step on the sea, in this case, how can naval battles be fought?" Lan Qian asked.

"Generally, we use bows, arrows, crossbows, etc. to carry out long-range attacks first, and then after the distance is shortened, we will carry out boarding battles and fight in close quarters!" Ma Keng replied.

"Is the power of the arrow crossbow great, can it destroy ships?" Lan Qian asked again.

"The power is okay, but it is impossible to destroy the ship, take our warship as an example, the wood used is the hardest dark iron wood, hard as iron, and there is no way for the arrow crossbow to penetrate it. Ma Keng replied, "The cost of each large warship like this is astronomical, so in every naval battle, the number of personnel losses is relatively secondary, and whether the warship has losses or not is the key!"

After listening to Ma Keng's words, Lan Qian slightly felt the hardness of the hull with his hand, and found that it was indeed very hard, comparable to a steel battleship on the earth. This level of hardness, I'm afraid that ordinary generals can't shake it, even if it's a martial marquis, it will take a long time for one person to destroy a ship.

"Do we have artillery here?" Lan Qian asked suddenly. On Earth, no matter how hard a battleship is, artillery can still do great damage to it.

"Cannon, haven't heard of it, what is that?" Ma Keng said suspiciously.

"It's a very powerful weapon!" Lan Qian thought as he spoke, it seems that this world has not yet developed such a thing as gunpowder, but compared to the earth, there is more spiritual power here, so maybe you can try it and see if you can develop a weapon like a spiritual power cannon.

Seeing that Lan Qian was in deep thought, Ma Keng stopped talking, for fear of disturbing Lan Qian.

For about a stick of incense, Lan Qian had been pondering, and at the same time, his right hand began to cast the Qi Condensation Technique to imitate casting. I saw that spiritual power cannons of different shapes were formed on Lan Qian's side, and then dissipated in Lan Qian's shaking of his head, and then formed and dissipated again, and so on, making Ma Keng on the side stunned.

"It's done!" Suddenly, Lan Qian said with a smile, "This design should be able to be used!" But the next moment Lan Qian frowned again, because he found that he couldn't fire the spirit cannon alone.

Because this spiritual power cannon was forged by Lan Qian with the Qi Condensation Technique, he had to maintain it himself, and firing the spiritual power cannon also required cannonballs and a highly compressed spiritual power source, so many things, Lan Qian obviously couldn't complete it alone.

"Do we have a blacksmith in our detachment, the kind that can forge all kinds of ironware?" Lan Qian looked at Ma Keng expectantly.

"Yes!" Ma Keng's answer made Lan Qian's eyes light up!

"But..."Before Lan Qian could get happy, he was suppressed by Ma Keng's "but", "Now on the sea, maybe he can't forge weapons." ”

"This..."

"Lan Gongzi wait a while, I'll ask!" After speaking, Ma Keng ran quickly and looked for the blacksmith.

Soon, after half a cup of tea, Ma Keng returned to Lan Qian with a big man.

"How is it?" Lan Qian asked as he looked at Ma Keng.

Looking at Lan Qian's expectant eyes, Ma Keng smiled and said, "No problem!

"Xiong Lun, come here!" Ma Keng called the big man over, and then said to Lan Qian, "Lan Gongzi, this is Xiong Lun, the leader of the 5th detachment, and a blacksmith, he has a 5-square space ring, just carry all the casting tools with him!"

"Okay!" Lan Qian breathed a sigh of relief, "Xionglun, I want to ask you to help cast a weapon, all the materials are up to you, I will buy it with you at double the price, if the casting is successful, I will have another reward, how about it? Captain Ma, if there are other blacksmiths in the detachment, please also come out to help, as long as there is someone who contributes, I will have a reward!" At this moment, Lan Qian's tyrant temperament is undoubtedly revealed, of course, Lan Qian himself does have this capital, and, according to Lan Qian's estimate, if this spiritual power cannon can really be cast, then if he doesn't take action himself, he can only control the spiritual power cannon, he can also exert great power!

Under the so-called heavy reward, there must be brave men, under the temptation of Lan Qian's huge interests, Xiong Lun immediately agreed, immediately took out the guy, and began to work.

At the same time, Ma Keng also spread Lan Qian's words, and for a while, all the blacksmiths were excited and ran over to help, but it was a pity that many blacksmiths did not have space rings, or the space rings were very small, and the things they carried were very limited. However, in the end, there were many people with great strength, and everyone worked together to make efforts, and finally barely managed to get all the materials together. After that, Lan Qian explained the imitation casting spirit cannon in his hand to the blacksmiths in detail, and everyone divided labor and began to cast different parts. In order to speed up the casting, Lan Qian also used a flame blessed with the spiritual power of the wood attribute to provide a fire source for the blacksmiths.

In this way, when the other warships fell into the dead silence before the war, the 5th detachment of the Fourth Army where Lan Qian was located was in a hot state, everyone had materials to produce materials, and those who did not have materials to send manpower, Lan Qian did not refuse, accepted them all, and handed over the money with one hand and delivered the goods with the other, so that the soldiers were full of smiles, and regarded Lan Qian as the God of Wealth.

Half an hour later, a rough version of the spiritual power cannon finally took shape, due to the poor conditions, it was already very good to be able to do this, so Lan Qian was not too demanding.

"Can you try it?" Seeing the spiritual power cannon in front of him, Lan Qian was eager to try, "First of all, let's try to see if we can get a highly compressed spiritual power source!" In Lan Qian's conception, this highly compressed spiritual power source is equivalent to gunpowder, it is the energy source of the spiritual power cannon.

For the highly compressed spiritual power source, Lan Qian himself has a ready-made one, that is, the Spiral Pill! The only difficulty is how to cast the Spiral Pill inside through the thick artillery iron wall.

Lan Qian came to the spiritual power cannon and put his hand on the spiritual power input device behind the cannon, this input device is the key to the entire spiritual power cannon, Lan Qian designed it as a one-way channel, only allowing spiritual power to enter, not allowing spiritual power to come out.

I saw Lan Qian holding his right hand on the spherical spiritual power input device, and through the dense one-way spiritual power input channel, Lan Qian began to condense the spiral pill in the cannon chamber. With the input of spiritual power, Lan Qian could feel that the spiral pill in the cannon chamber was gradually forming, but just when Lan Qian thought that he was going to succeed, the spiral pill suddenly went out of control and exploded.

Boom!

I saw a wave of spiritual power rushing out of the cannon, rushing into the air more than ten meters high before dissipating, and the powerful recoil also shook the spiritual power cannon.

"Wow!" On the warship, the audience was in an uproar, and the soldiers of the 5th detachment obviously did not expect that this weapon that they had never seen before could exert such a strong power, and it seemed that it was just a failed work just now, if it could be successfully used, the power would definitely be even greater. Before, some of the people were holding the attitude of onlookers to see what kind of fame this Moyu Dabi champion could make, and some were trying to make money and treating Lan Qian as a cash cow, but now seeing the power of the spiritual power cannon, everyone's thoughts changed all of a sudden, and they began to notice the extraordinaryness of the spiritual power cannon.

Summing up the experience of the first failure a little, Lan Qian began to conduct the second test, but it backfired, and the second test was finally declared a failure, obviously, casting the spiral pill through the iron wall was not as easy as Lan Qian imagined.

After that, Lan Qian failed more than a dozen times in a row, which made everyone's confidence full of expectations drop to the freezing point.

"It seems that although this thing is very powerful, it is not so easy to use!"

"Yes, the more powerful, the more difficult it will be!"

"I think this time eighty percent will be..."

"Shut your beaks for me!" Ma Keng roared, although he didn't have much confidence in this spiritual cannon now, he didn't want his subordinates to chew their tongues in front of Lan Qian.

Just when everyone thought there was no hope, Lan Qian shouted, "It's done!"

"It's finished?"

"Shoot the cannonball!" Lan Qian shouted again, and now he could only barely maintain the Spiral Pill, and he couldn't hold on for long.

"Hurry up and release the cannonballs!" Ma Keng also hurriedly commanded. Immediately, two of his subordinates hurriedly put a black iron ball into the barrel of the cannon. The current cannonballs are just ordinary round iron balls, and after the spirit cannon can be used normally, there is still a lot of room for improvement in the material and shape of the cannonballs.

"The shells are installed!" replied one of the soldiers.

"Okay!Spirit Cannon, fire !!" Lan Qian shouted, then withdrew his right hand from the Spirit Cannon.

With the withdrawal of Lan Qian's right hand, the highly compressed and rotating spiral pill inside directly lost control, and then it was released explosively. Since the spiritual power injection channel is one-way, the release path of the spiral pill's spiritual power at this time is only in the direction of the cannonball in front!

Boom!!

There was a loud bang, deafening! Several soldiers who were closer were temporarily deaf. But what stunned them the most was that the cannonball shot into the air at a speed that the naked eye could not keep up with, and after a few breaths, it hit the bottom of the sea with a "boom", setting off a huge wave!

"Hiss!" Ma Keng and the others all gasped, this power was a little too great! Even Lan Qian himself was surprised, this power was much more powerful than the Spiral Pill itself. However, if you think about it carefully, you will understand that when the Spiral Pill releases its power, it is released in all directions at the same time, and now, Lan Qian uses the spiritual power cannon to concentrate all the power of the Spiral Pill in one direction, and the power is naturally greater than normal, and it is much, much greater!

"Is it possible for this power to penetrate the warship?" Lan Qian asked with a grin.

"It's hard to say at a distance. But if you attack within 100 meters, I think it should be fine!" Ma Keng replied conservatively, "With this spiritual cannon, we can definitely surprise the Jiao family, if our 5th detachment can destroy a warship, then this time it will be a great achievement!" Ma Keng was in a good mood at this moment.

"Of course, this credit belongs to Lan Gongzi!, but our 5th detachment can also get some light, hahahaha!" Ma Keng said and couldn't help laughing at the end.
