The ravine under the northern city wall, which was more than two meters deep and five or six meters wide, extended five or six hundred meters from under the city wall until it reached the ruins of a high-rise building outside the territory of the War Alliance.

The whole gully was in a crystalline state, and you can imagine how high the temperature was after this cannon was fired!

"What about the rate of fire? Also, is it very expensive? Song Jian asked.

"You can only fire once a minute, not enough to activate the rapid-fire skill, and the time is shortened to ten seconds!" Wang Qi said: "After activating the rapid-fire skill, the energy consumption is accelerated by three times, and it can only last for one minute, and after the time is over, the railgun needs to cool down for ten minutes before it can continue firing!" ”

"As for the energy ......" Wang Qi frowned slightly, and said in a low voice: "The consumption is extremely high, with our storage, according to the calculation of the two magic crystal railguns, even if it is just shooting according to the normal state, it can only last for about half an hour, if you start rapid fire, I am afraid that after using it once, this railgun can no longer be used!" ”

Song Jian frowned slightly, the energy consumed by the magic crystal railgun is the magic crystal, and this kind of material, no matter which city it is, is a strategic material that is prohibited from being sold.

The City of Hope also bought some at a high price with the help of the Sin Capital, which was used to make magic crystal railguns, and the remaining magic crystals were simply not enough to support a fierce battle;

This is also the reason why Song Jian did not continue to farm the boss to obtain materials, it is not enough to have a railgun, there must be enough ammunition!

"Demon Crystal, Demon Crystal......" Song Jian frowned and asked, "Isn't there a Demon Crystal Mine in the City of Doom?" ”

Wang Qi showed a wry smile on his face: "The magic crystal is probably the most difficult material to obtain in this game, not only the city of doom, even if it is a big city like the capital of sin and the city of songs, there are no magic crystal mines around!" ”

"At present, there are only three magic crystal mines found in the entire game, and all of them are in monster areas above level 50, and they are more than 100 ......kilometers away from the nearest city," Wang Qi said.

All of his information was obtained from the capital of sin, the material of the magic crystal, Wang Qi didn't say that he had seen it before, and he hadn't even heard of it, but this time he was going to build the magic crystal railgun, so he made up for this knowledge;

Song Jian sighed in his heart, it seems that these two railguns can only be used at the most critical time, and cannot be used as conventional weapons!

"When will another railgun be built?" Song Jian asked.

"It will take four more days, and it can definitely be built before the mission is over!" Wang Qi said.

"How many defensive buildings do we have now, and is the defense up to standard?" Glancing at the dense array of war equipment on the city wall, he asked.

"Hehe, it's already up to standard, and now the overall defense of our city has reached 165,000 points, and when the magic crystal railgun is built, it can also increase the defense by 30,000 points!" Wang Qi said with a smile;

Originally, the defense level was the most headache link, and the defense buildings provided by the system were all fully built, and there was only a maximum of 60,000 defense degrees, which was still a cut away from the standard.

But now, by the end of the mission, the defense of the City of Hope Alliance's defense will almost double compared to the mission requirements!

The higher the degree of defense, the safer the defending players will be, and the more people will naturally be willing to participate in the defense, otherwise, I am afraid that the entire City of Hope Battle Alliance, I am afraid that there will be a large number of people who withdraw from the alliance in the monster siege link;

In this game, there is only one human life, as long as you live, there are infinite possibilities, no matter how big the benefits, no one is willing to exchange their lives!

Hearing that the defense degree can reach close to 200,000, Song Jian finally nodded with satisfaction, the higher the defense, the better, even if all the buildings are destroyed in the end, as long as the core of the battle alliance of the manor castle is still there, and the players in the battle alliance are still there, it is a victory!

The materials have been collected, the defense has also reached the requirements, and two of the four missions have been completed, leaving only the clearance mission and waiting for the final monster siege!

The clearance task does not seem difficult, but it is the most tedious part, and if you want to do it to the extreme, you must not have a system monster in your territory!

Whether it is on the ground or in the sewers, it has been inspected several times, but every time there are always some new monsters, this is the most headache for Wang Qi, sometimes I really want to turn the whole ground over to find it!

Song Jian glanced at the loyalty of the hive, it had increased to sixty points, it seemed that the feeding had been good in the recent period, even the beetles had hatched more than 30,000, and according to the ratio of ten to one and one hundred to one, there were also three thousand strong beetles and three hundred elite beetle guards;

It's just that the more powerful abyssal beetle has never appeared, and it seems that the probability of hatching the abyssal beetle is much smaller than it shows;

At this moment, Song Jian suddenly felt the ground tremble slightly, but this tremor was very slight, and only when his mental value had exceeded 100 points did he feel it, and Wang Qi and the other players beside him didn't notice it at all;

"What's going on?" Song Jian frowned slightly, and at this time, he suddenly felt a trace of weakness transmitted to him from the hive, accompanied by a feeling of hunger.

When Song Jian opened the interface of the hive, he was shocked to find that the hive had hatched an abyss beetle!

"Prepare a lot of food and send it to the sewers, be quick!" After Song Jian finished speaking, he ran directly towards the entrance of the sewer;

The beetles hatched by the hive, Song Jian cannot directly control them like the black dragon and the blood beast, he must control them through the hive, so he can only see the number of beetles hatched by the hive, as for the specific attributes of each beetle, it cannot be seen from the interface.

Just hatching an abyssal beetle, the movement is bigger than hatching more than 30,000 beetles, which makes Song Jian very curious in his heart, how strong is the attribute of this abyss beetle!

Before coming to the hive, Song Jian saw that a large number of monster corpses had been piled up here, many of which were elite-level boss corpses, of course, Song Jian was the one who contributed the most, after all, during this time, he was the only one who was constantly brushing the elite bosses above level 30.

Although the strength of many bosses is too late to be transported here, just a small number of boss corpses is enough to greatly increase the loyalty of the hive to Song Jian;

Looking at the beetle the size of a car in front of him, Song Jian couldn't help but guess in his heart that maybe it was because of devouring the corpses of these high-level bosses that the hive could produce abyssal beetles;
