Long Yichen's heart was tumbling in a turbulent wave, but the expression on his face was extremely calm, and he nodded slightly: "Well, yes, this thing looks quite big, but I don't know how powerful it is, especially on land, when attacking the city, can it blow up the city wall, and the range is a little closer." ”

Dai Yisi originally thought that Long Yichen would be subdued by the cannon, but she didn't expect that this Long Yichen would put forward such a bunch of shortcomings.

And these shortcomings do exist.

Dai Yisi frowned and did not speak.

Long Yichen glanced at her and said: "I have read about this kind of thing in a book before, but the weapon described in that book is different from this, the range is super long, and it is very powerful, it can directly collapse the strong city wall, why don't you show me your drawings, and I will see what is wrong." ”

Dai Yisi suddenly aweed him, "You still have this, it's amazing." ”

Dai Yisi took Long Yichen to their arsenal in Karoxi Kingdom, handed over the technical engineer there, and asked him to bring the drawings over to Long Yichen to see.

Long Yichen looked down at the drawing, the more he looked at it, the more he admired, and the more he looked at it, the more frightened he became.

With such a powerful weapon, if he could have it, why couldn't he defeat Long Xilin?

The power of these weapons, he had seen just now, was even more powerful than Long Xilin's weapon.

"Chenchen, do you see it? What's wrong? Dai Yisi asked.

Long Yichen said seriously: "This design is already more complicated, and it is not so easy to find out the problem, so it is better to let me take it back and take a closer look, maybe I can find out what is wrong." ”

A trace of suspicion flashed in Dai Yisi's eyes, but she was very attentive to Long Yichen, and this was originally a blueprint of an older version of a cannon, so she was not afraid that he would take the drawings away.

Dai Yisi smiled slightly: "Okay, this time you go back, just bring this drawing back, not only that, I will send another engineer to Longling Kingdom with you, if you find out what is wrong, just tell the engineer directly." ”

"Okay." Long Yichen couldn't ask for it.

The next day, Dai Yisi personally led an elite guard to accompany Long Yichen back to Longling Kingdom.

Between the country of Karoxi and the country of Longling, there is a sea area, and Anjiang City is a city near the sea, and Karosi's warships have been sailing towards the port of Anjiang City, preparing to wait for the shore from Anjiang City.

Xu Youcai, the defender in Anjiang City, became vigilant when he discovered an unusual warship on the sea, secretly mobilized a fleet and waited for the battle.

However, in the first round, Xu Youcai's side suffered a big loss.

Because the level of weapons was too different, Xu Youcai's ships were burned by the opponent's cannons one after another.

Xu Youcai realized the seriousness of the matter, and on the one hand, he sent someone to inform Long Xilin of this military situation, on the other hand, he analyzed the actual situation of the two sides, and found that although the opponent's weapons were powerful, the range was relatively short, and when they fought again, Xu Youcai avoided their battleship from a distance, and at the same time attacked the crew of the Karoxi ship with machine guns.

This one, although it is impossible to sink Karosi's warship, it can make them afraid of it, so that they do not dare to move forward.

……

At this moment, Long Xilin, who was thousands of miles away, was also caught in a tug-of-war.

The Philadelphia guards and soldiers were closed, and Long Xilin and his men set up camp outside of Philadelphia.
