The roar seemed to be a signal, and all the skeletons and zombies stopped moving forward, as if they had pressed the pause button while watching a movie, and stood still in place, which looked very eerie.

Of course, the human side would not give up this opportunity, and thousands of beams of light of different thicknesses lit up the starry sky and slammed into the monster horde.

Large swaths of monsters fell in the ferocious bombardment, and suddenly a lot of blank space appeared in the monster group, like lepers, bald here, bald there.

"Roar!" In the face of the bombardment of humans, the monsters naturally did not remain indifferent, and with the sound of a loud roar, the monsters once again launched a fierce charge that was not afraid of death.

Colorful elemental attacks and dense bone arrows rose from the horde of monsters, overwhelmingly enveloping the city walls.

In the face of such a dense attack, the human race had been prepared for a long time, only to hear a 'buzz', and an energy shield rose up on the city wall, blocking the first wave of attacks from long-range monsters.

The shield's defense is two-way, not only can it resist the attacks of monsters, but the attacks of humans on the walls will also be blocked by the shield.

Naturally, for the safety of the soldiers on the city wall, the monster rushed under the city wall, and immediately removed the shield after blocking the next wave of attacks, and at the moment when the shield disappeared, thousands of beams shot out in a volley, harvesting a wave of skeleton zombies again.

The turn-based game begins, and the fight back and forth is extremely intense, and the monster legion kills and wounds a large number of cannon fodder, while the human soldiers naturally do not go undamaged, and some attacks will fall on the city wall when the protective shield is closed, but fortunately, the casualties are not large.

"Milk, Brother Sun is awesome, even flying arrows can hit." Li Dasheng gave Sun Tu a thumbs up.

Just now, a white bone arrow shot at Lin Sheng, who was preparing for the ability, at the moment when the protective shield disappeared, Sun Tu instantly completed the cutting of the gun, and raised the assault rifle is a 'sudden burst' of an accurate triple shot, blasting the arrow in mid-air.

"Thank you." Lin Sheng broke out in a cold sweat, the speed at which the arrow flew was even something that he, a yellow-level nine-star wind powerhouse, could dodge, if it wasn't for Sun Tu's action, he would at least be injured.

"No thanks, this is what I should do, you can attack with confidence, as long as it is not an attack launched by a ground-level monster, or the attack density is too high, I am confident that I can block it." Sun Tu gave everyone a reassuring expression, and then picked up the sniper rifle again to shoot the Xuan-level monster.

"Hehe, I still have a good vision and pulled Sun Tu into the team." Tan Wen had a smile on his face, with such a strong teammate protection, he was able to let go of his hands and feet to attack.

"Ding, congratulations on the host upgrade, as level 12, all attributes +2, free attribute points +2."

After the Xuan level, the upgrade experience directly increased by a hundred times, and the experience of the yellow-level skeleton was halved, and more than three hours passed, and Sun Tu was only upgraded by two levels.

"It's finally escalated, this damn experience is too bad." Looking at the experience required to reach level 13, Sun Tu couldn't help but complain.

Experience: 12/300000.

You must know that the monsters of the Xuan-level one-star only have 100 points of experience, and the monsters of the Xuan-level nine-star only have 900 points of experience, that is, Sun Tu must kill at least 334 Xuan-level nine-star monsters to level up.

Some people will say that teammates can also gain experience by killing monster Sun Tu, with the help of eight ability teammates, it shouldn't be slow to level up, but don't forget that teammates can only gain one-tenth of the experience when they kill monster Sun Tu.

In addition, only four people in the team have reached the Xuan level, and the attacks of the other four people are difficult to cause damage to the Xuan-level skeletons, among which Luo Yiyi, who is a one-star of the Xuan-level level, is biased towards assistance, and it takes at least two minutes to kill the skeletons of the Xuan-level one-star alone, and only the fire-based ability Huang Ying, the thunder-based ability Song Shuai, and the object-controlling ability Tan Wen can quickly kill the Xuan-level monsters.

But the highest is to kill monsters that are one or two stars higher than them, and no matter how high it is, it will take a long time, and there is also a spell ability that requires magic energy, although there is a magic potion to replenish, but it also takes time to recover.

Sun Tu wants to have a hundredfold experience pill, but unfortunately this system doesn't even have a store, even if he has money, there is no place for krypton.

Helpless, Sun Tu entered the system backpack, and during this time, a lot of materials exploded, and he decided to make firearms and improve the proficiency of his skills.

"System, start making the Skeleton Thug pistol." Sun Tu took ten materials and entered the weapon workshop, and directly turned on the automatic manufacturing function.

"Ding, it takes ten minutes to make a Bone Thug Pistol (double guns), please be patient." As the system prompt sounds, the workshop is up and running.

For this automatic manufacturing function, Sun Tu said that he was very satisfied, he didn't need to do it himself, as long as he provided materials, the only drawback was that he needed to consume magic energy stones, and he needed to consume a yellow-level magic energy stone to make a yellow-level firearm.

Now Sun Tu doesn't lack magic energy stones at all, anyway, he doesn't need to spend money to buy magic energy stones, he didn't even think about paying for ten magic energy stones directly, and then he just needs to wait.

"The defense of the Xuan-level zombie is too strong, my ability can't break through the defense at all, can Sun Tu give me some more elemental magic energy stones? Or is it better to cast the magic stone you cast the ability on. Luo Yiyi grumbled with a small pout.

Her ability attack power is not strong in the first place, and it is a little reluctant to deal with Xuan-level skeletons, not to mention zombies with stronger defenses, if the defense is broken, then there will be ghosts.

As soon as Luo Yiyi's words were finished, Sun Tu felt several hot eyes looking at him.

You don't need to look at Sun Tu to know who the owner of these eyes is, and the eight people have all used the elemental magic energy stone provided by Sun Tu, for this kind of magic energy stone that can kill monsters beyond the stars without any effort, the eight people said that they all want it.

Looking at Luo Yiyi's expectant gaze, Sun Tu still couldn't ruthlessly refuse this girl who was kind to him.

"Yes, but not much, barely enough for two people." As he leveled up, his energy regeneration became faster and faster, and now he could use the Elemental Specialist skill non-stop, but he didn't want to become a logistician.

"That's great, little plum, let's change positions." Luo Yiyi ran over and squeezed Li Dasheng away directly.

"Brother Sun, you have to seize the opportunity, if you can win Luo Yiyi, you don't have to fight in this life, you just need to eat and wait for death." Before Li Dasheng left, he whispered in Sun Tu's ear.

", is my brother that kind of person?" Sun Tu said angrily.

Li Dasheng gave Sun Tu a 'you are the kind of person you look' and then left in a hurry.

To be honest, Luo Yiyi is not only beautiful, but also very rich in his family, and he is a standard white rich beauty, but Sun Tu, who is a bit machismo, never thought of eating soft rice, although his current appearance is very much like a little white face.
