Different from the heavy and heavy horns of the previous assembly horns, the sound of the emergency alarm bell located in the center of the city is very rapid and very penetrating.

At the same time, the two Yu Tu also accepted a new task, requesting to go to the front wall for defense.

Yu Tu frowned and said, "It seems that the enemy's main attack direction is not here. It has been set."

"Let's go over and take a look."

"Stay away. These people use us as cannon fodder. It's not worth dying in such a place."

"Of course, I don't want to either."

Yu Tu took Yu Shuang back to the ground and hurried slowly to the front wall.

After spending nearly half an hour, the two people passed through the entire city and came to the third wall of the front wall. And the second city wall in front of them has completely reduced to a battlefield.

A large number of amphibious sea beasts have rushed into the city wall, fighting with the guards and players inside. For these sea beasts, the moat in front of the second city wall is not an obstacle at all.

Before, the subsequent city wall defense magic consumed a lot of mana. Leading to the lack of magic in the entire city wall. The current second city wall can only open a magic shield that consumes less energy to resist the enemy's long-range magic attack.

"Yu Tu, what shall we do? Do we want to go over?"

"Better not. This level of melee, personal strength is suppressed to the extreme. On the battlefield, most of the fatal attacks are lost. No one can guarantee that he can fight in all directions while fighting. defense."

At this time, a team of guards rushed over and saw Yu Tu, a group of fish-fishing players.

The captain of the squad came over and said loudly: "There is no time for you to stand stupidly here, hurry up and help arrange the defense. You two will go with me, and the others will follow their arrangements. Move fast, you can’t stand it soon. Up."

After speaking, the team leader took Yu Tu and left without waiting for other people to object.

After walking away, the team leader turned his head and said solemnly to the two of them: "Mr. Carlos entrusted me to take care of you, but I hope you understand that this is a war and I can't even guarantee my own life. All I can do is arrange Give you a relatively safe position."

Yu Tu said: "Can I know what is going on now?"

"Very bad. The enemy's main attack direction we guessed wrong has used most of the magic power of the White Wall to clean up other positions. This also leads to the fact that the White Wall cannot use powerful defensive magic."

"Except for the wall in the direction of the mountain wall, other walls are attacked by a large number of sea monsters, making the magic of the wall of the white wall unable to recover quickly. Basically, the function of the wall of the white wall is no different from the ordinary wall. It can still be supported now. Now, it's all the time that is piled up by the lives of your heavenly descendants."

"Now, we must strengthen the defense of the Pure Blue Wall as soon as possible. We are here."

Under the leadership of the team leader, Yu Tu and the two came to a position near the corner of the city wall. A large number of people are carrying boxes of magic stones. Obviously it was prepared for the magic cannon on one side.

The team leader said to the one-eyed middle-aged man who was debugging the magic cannon: "Senior Sikri, I arranged for these two people to be here to help you,"

"I see, don't worry."

The team leader nodded, turned and left.

Sikri stood up straight, the height of more than two meters gave them a huge sense of oppression.

Sikri looked at the two and asked, "Can you use a cannon?"

"untested."

Sikri turned around and picked up a magic spar and said: "Look, every magic artillery has its upper limit and use limit. Filling the magic crystal must be in this range. It's too big, the magic cannot be completely cast. It will cause the chamber to explode. If it is less, the impact of the magic is insufficient, and it is very likely that it will not be launched.

Sikri opened the filling port on one side and said: "After each use, it takes ten seconds to stand still. During this time, you can't touch it. When filling, just like that, open the filling port and take out the waste with this shovel. . Then, this coolant, put it in first, and then fill the magic crystal. Wait until the coolant is fully effective before filling the opening. Complete a filling."

Sikri went on to say: "You, are responsible for filling it for me. Remember, the steps can't go wrong. Little girl, you are responsible for carrying the magic crystal. The approximate size is like this. Make no mistake. I am not kidding, it is related to ours. Fate. If you are clear, prepare quickly. The white wall is about to fail."

Yu Tu didn't say much, and immediately devoted himself to their work. Yu Tu did the refilling step by step and quickly became familiar with it.

With the help of Aiwen, Yu Shuang distinguished the magic content in the magic crystal and prepared ammunition.

Did not give them too much time. There was a loud noise from the front.

Everyone present raised their heads and looked at the white wall. On the tall city wall, a hole nearly ten meters in diameter looked so eye-catching. A large number of sea beasts are stepping on the body of the guards, passing through the cave, and rushing towards the last city wall.

"Ready for artillery fire, free shooting!"

After receiving the order, Sikri immediately sat on the turret, using his hands and feet together, and quickly adjusted the angle of the magic artillery.

After waiting quietly for a few seconds, after the enemy had passed halfway, Sikri fired up the cannon.

Hundreds of magic artillery roared almost simultaneously. Magic groups of different colors bombarded the monster group, and instantly swallowed the monster in front.

But the monsters behind were not afraid at all, and they still rushed forward recklessly.

"Okay, change the bomb."

Yu Tu had already opened the loading bin when SGL gave the order. Finished the filling skillfully. Yu Shuang also quickly cleared away the magic crystal residue.

Adjusting the angle again, Sikri launched another attack. This time, Yu Tu didn't need him to speak out, and Yu Tu completed the reloading with time.

Gradually, the three of them all adapted to each other's rhythm and began to work like machines.

With the suppression of artillery, the enemy's attack speed has been reduced a lot. But still unable to stop the enemy from rushing up the wall.

At this time, it was the players and guards' turn to play. Players and the guards clean up the monsters that climbed the city wall, guarding important defense tools such as artillery.

Yu Tu was also attacked by the enemy. But these monsters can be solved perfectly by Yu Tu. To ensure safety, Yu Shuang also summoned vine giants to assist in defense.

Being the last line of defense in the city, the guarding power of the Pure Blue Wall is not what players can imagine now. Different from the magical defense of the white wall, the strength of the pure blue wall lies in its solid material and 100,000 defense equipment.

However, the enemy is not a simple role. Through the hole in the white wall, a tall shadow approached the city wall.
