Yu Hao returned to the Sword Fortress with thirty magic crystal cannons, these magic crystal cannons were all made by Master Zhixian, he specifically asked Master Zhixian, the cost of the magic crystal cannon is about 20,000 gold coins, because the materials are limited, so it took so long to make so many magic crystal cannons in the arsenal. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Now that the workers and technology of the arsenal are fully mature, if the materials keep up, the horsepower can make almost fifty magic crystal cannons in one day, he specially called Li Meng to the arsenal and gave the other party three million gold coins, so that he could buy the materials of the magic crystal cannon as quickly as possible, and let Master Zhixian not be careful, and he could make a hundred magic crystal cannons in three days.

In fact, thirty magic crystal cannons is not a small number, as far as the ordinary cities of the dark camp are concerned, a city is only twenty magic crystal cannons at most, and even a medium-sized city has no more than fifty magic crystal cannons, but Yu Hao wants to build a war fortress, not a city's defense system, so he wants one cannon after another.

Fortunately, his own arsenal produces magic crystal cannons, if he is allowed to buy them, he estimates that they will cost at least 200,000 gold coins, after all, it is normal for such things as arms to make ten times the profit.

After Yu Hao arrived at the Sword Fortress, he took out all the magic crystal cannons, and then he and Liyin commanded their respective pets to move these cannons to the designated place, at this time the gunner also came with the members of the cannon team, and the matter of installing the magic crystal cannon Yu Hao handed over to the gunners, and he and Liyin's pets were on the side, after all, whether it was the base or the barrel.

Yu Hao miscalculated this time, he thought that it would be easy to install the magic crystal cannon, but he ignored a problem, that is, the surrounding natural city walls have become extremely hard under the tempering of lightning, and it is very difficult for him to install the cannon on it, and it is difficult for him to choose for a while.

Because it is difficult to develop the station in the future, the city wall will also be unable to be upgraded due to the level of the station, which also creates an embarrassing situation that the earth wall cannot bear the recoil of the magic crystal cannon.

"Helper, what's the matter, such a strong city wall is not comparable to the city wall of a large city, even if the city wall is equipped with more magic crystal cannons, it can withstand it, but the question is how can we install these cannons." The gunner looked at Yu Hao and Liyin and spoke.

Yu Hao frowned deeply, he knew what the gunner said, if it was hard to install, it would be fine, but the speed would probably be turtle speed, and it would be good to be able to load ten in three days, if he didn't install it, wouldn't he have no strong firepower in this war fortress, and it was still a war fortress at that time?

"I think the reason why there are fewer magic crystal cannons in other cities is not because they don't have them, but because the city walls can't afford it." Liyin looked at the hard mountain stone and said thoughtfully.

"Leave the gang leader, shouldn't we think of a way at this time!" Yu Hao rolled his eyes, when is it to go into seclusion, and he still has the kung fu to sigh about the other.

"Uh... Isn't that what I'm thinking? Liyin said embarrassedly, it was the first time to contact a cannon at such a distance, what could he do.

"If only there were explosives, they all exploded with a bang!"

“....”

Yu Hao and the gunner looked at Liyin speechlessly, and the other party thought of such a constructive idea after holding back for a long time, not to mention whether there was a cannon or not, wouldn't this explosion blow up the city wall?

The three of them stood on the city wall and looked at the lush greenery in the distance, and they had no idea for a while, the recoil of the magic crystal cannon was huge, unless the base was directly hit into the city wall, otherwise the magic crystal cannon would fall apart as soon as the shot went down, so the idea of temporarily reinforcing the base was not advisable.

Yu Hao didn't expect to be bothered by this question, it was really a city wall defeat and a city wall, and he finally decided to ask Master Jixian to see if the other party had any good solutions.

"What? You said that the natural city wall was very strong, and it was difficult to install the magic crystal cannon? Master Zhixian frowned, he hadn't been to the scene, so he didn't know much about the specific situation, even if he was in a hurry now, I'm afraid he wouldn't be able to reach the fortress before the monster attacked the city.

"yes, I doubt that the magic cannon can leave a mark on the city walls." Yu Hao said helplessly.

"It's so hard." Master Jihyun walked back and forth, and Woo Ho had to wait here when he saw this.

"By the way, did you go to Tarys?"

"Tarys? What are you looking for him? ”

"He's an alchemist, maybe there's a way to deal with those hard stones easily."

"That's right! How could I not have thought of it! ”

Yu Hao slapped his thigh, Taris has been studying some strange things all day long, maybe the other party really has a way, he said goodbye and went to find Taris in a hurry.

If you want to talk about Taris, it's really not easy recently, he has to do experiments and refine medicine, so he has a big opinion, but who let his younger brother lead the troops to fight now, so he has to go into battle in person, after all, the potions used by NPCs are a little different from those used by adventurers, and those alchemy apprentices of Yu Hao can't refine the potions needed by NPCs at all, and he only has the potions of his brother's army to protect himself.

Yu Hao went to Taris's courtyard, and he was glad to know about it, after all, Taris would reduce the casualties of his legion a lot if he did this.

"Taris, can you put aside what you're doing for the time being, I'm looking for you to get down to business!" Yu Hao looked at Taris and said dissatisfied, he has been refining medicine since he came in, even if the two of them talk to each other, they have not stopped what they are doing, and sometimes he has to repeat a sentence several times.

"You say, I listen, I'm refining a thousand bottles, and I can ask someone to send these medicines to Tarifi." As Tarys spoke, he picked up another herb and prepared to refine it, and Yu Hao quickly grabbed the other party.

"Taris, it's okay to delay you for a few minutes, you wait for me to finish refining medicine, otherwise I'll drop Tarifi back from the front line!"

"Okay, say it!" When Taris heard this, he had to compromise, so he stared straight at Yu Hao, urging him to hurry up.

After Yu Hao told Taris about the difficulty of installing the magic crystal cannon, the other party ran into the room without saying a word, and when he came out, he already had one more thing in his hand.

"Cutting machine..."Yu Hao looked at Taris with a black line on his face, although the material of this thing was different, but he recognized this as a cutting machine at a glance, the current cutting machines are very small, but Taris's is even smaller, almost the size of a palm.

"What a cutter, this is the king of destruction, I invented it!" Taris has a good airway, and some materials are harder than diamonds, so he once had a headache and later invented the King of Destruction.

Yu Hao didn't expect that this King of Destruction consumed magic crystals, it seems that high-end things commonly use magic crystals, and after he mastered the method of use, he left the station with the King of Destruction.
