"Ding, kill the Xuanji two-star skeleton and get a copy of the essence of the Xuanji bone."

"Whew!" There was another muffled gunshot, this time a black beam, and a Xuan-level zombie 150 meters away suddenly stopped charging, and then fell straight down.

"Ding, kill the Xuanji three-star zombie, get two Xuan-level zombie fangs, and one Xuan-level soul fragment."

Very lucky, the feature annihilation was triggered, and it was directly spiked.

"Ness, try the power of the two guns again." Sun Tu searched for a test target among the monsters below.

But after searching for a few minutes, I didn't find a suitable object, and these monsters that rushed to the front were cannon fodder for consumption, and their strength was generally not high.

The effective range of the thug pistol was only two hundred meters, Sun Tu had a feeling that the whip was beyond his reach, and he finally saw a relatively high-level zombie, but before he could make a move, a long row of beams with a diameter of half a meter instantly swept all the monsters within 100 meters of the city wall, and when the light dissipated, where could the shadow of the zombie be found.

The target of the beam cannon hidden in the city wall is the monster that rushes to the front, the range of the beam cannon is not far, only two meters and a hundred distances, and the beam cannon equipped with a special sensing device will launch a carpet bombardment as long as it senses a large number of monsters within a hundred meters of the city wall.

If the human soldiers and heavy weapons on the city walls are the first line of defense against monsters, then the beam cannon is the second line of defense, and the dense bombardment effectively stops the monsters from advancing.

"A two-gun combination might break through the defenses of the two-headed zombies, and if you're lucky enough to trigger a lethal hit, the mission can be done, but the distance is not enough, and it would be nice if this trait appeared on a sniper rifle." Sun Tu was very helpless.

A little depressed, Sun Tu could only put the thug pistol that had little effect back into the arsenal, and by the way, he put a box of Xuan-level magic energy stones into the ammunition depot.

"System, recover the other nine pairs of skeletal thug pistols." Sun Tu looked at the ordinary thug pistol that occupied nine squares, and couldn't help but say to the system.

"Ding, the recovery is successful, and you can get nine pistol enhancement stones."

"Enhancement stones can strengthen firearms, which can greatly increase the power of firearms, and the corresponding enhancement stones can only strengthen the corresponding firearms."

"Nima, dig me again." The moment he heard the strengthening stone, Sun Tu thought of the evil street girl in the poisoned milk powder, who made him eat instant noodles for two months in order to strengthen a +15 weapon, and wanted to vomit when he smelled the smell of instant noodles for a long time after that.

"System, if the two-headed zombie is killed by someone else, how does it count?" Sun Tu could only pray that the two-headed zombie would be killed by others to complete the task.

"Count as a mission failure, please complete the task as soon as possible, according to the system calculation, the two-headed zombie will enter the beam cannon coverage after twenty minutes, and friendly reminder, don't try to wait for the two-headed zombie to enter the range of the thug pistol, because its path will not be within two hundred meters of you." The emotionless mechanical sound of the system completely shattered Sun Tu's last bit of expectation.

Sun Tu secretly said in his heart, NND! The experience I've saved up for more than two hours is going down the drain, and the skills I hope to be downgraded aren't important skills.

"But every skill counts!" Sun Tu looked at the skill, and suddenly a passive skill that could not be upgraded appeared in his eyes.

The passive skill is weak and broken, hitting the weak point and dealing 200% damage, with a small chance of a critical hit (the critical hit ignores level and defense).

"There is no way to be endless, how awesome skills have been ignored by me, as long as the fatal blow is triggered, it is not impossible to hunt the two-headed zombies of the Xuan-level nine-star." Sun Tu clenched his fist hard, then picked up the assault rifle and loaded it with the magic energy stone inflicted with the light and fire element.

Next, Sun Tu showed everyone what is called a pressure gun, the muzzle of the gun kept spitting out beams, and the assault rifle seemed to have no recoil in Sun Tu's hands, which was also due to the optimization of the body, so that the body fit the profession of sharpshooter, otherwise even if the strength reached the ground level, it would not be able to do this.

The beams containing the two elements of light and fire are almost connected in a straight line, accurately hitting the heart of the two-headed zombies mixed in the zombie horde.

Since this zombie has two heads, Sun Tu didn't know if the head was an Achilles heel, and finally felt that it was safer to hit the other weakness.

"Boom, boom!" The firelight instantly engulfed the two-headed zombie, and I have to say that the defense of the Xuan-level nine-star zombie is strong, and when a magic energy stone is consumed, except for stopping the two-headed zombie's progress and leaving a bowl-sized scorched black on its chest, there is no substantial damage.

"Made, I don't believe I can't trigger the fatal blow today." Sun Tu wanted a heavy machine gun so much, but that thing had a high physical fitness requirements, and now he couldn't operate it at all, so he could only retreat to the next best thing, borrowed an assault rifle from Luo Yiyi beside him, held a rifle in each hand, and pulled the trigger frantically.

The two-headed zombies were instantly engulfed in flames, and the nearby zombies below the three-star level were also affected by the pond fish, they did not have the high defense power of the two-headed zombies, and they fell down one after another and turned into experience points and materials for Sun Tu's upgrade.

", Brother Sun, I'll give 99 points for this wave of operations, I'm afraid you'll be proud of one more point."

"666, you can still hold a gun in both hands and be so stable, you are simply born for firearms."

"Pervert, this firepower is almost as good as a heavy machine gun, this guy won't be hanging."

"Brother Sun, please take my knees."

"Everyone has a waist disc, why are you so protruding, I've already laid down, the big guy begged to fly."

"Hahaha, with this demon, why don't you get the first place today, it seems that you don't need to go back to inherit tens of billions of family property."

A few friends were stunned by Sun Tu's operation, the recoil of the magic energy gun is still very large, the higher the level of the magic energy stone used, the greater the recoil, and the recoil of the Xuan-level magic energy stone can only be done if the strength reaches the ground level.

"This is just the basic operation, and I will show you the dual-wielding Gatling heavy machine gun when I have a chance later." Sun Tu was very happy now, two rounds of wild shooting consumed four Xuan-level magic energy stones, and finally heard the prompt sound of the system, so he decided to pretend to celebrate.

"Ding, kill the Xuan-level nine-star mutated double-headed zombie, get a essence blood bead, eight Xuan-level zombie fangs, and a Xuan-level soul fire."

"Ding, congratulations to the host for completing the task, obtaining 50,000 experience points, and a blueprint for the bloodthirsty fangs shotgun."

"Hey, what's the Essence Blood Bead?" With questions, Sun Tu separated a part of his consciousness and entered the system backpack to check.

Essence Blood Beads: After taking it, it can increase the strength of the body, slightly improve the body's self-healing ability, without any side effects, and can be taken up to 10 pieces per person.
