Overall, the four new professional skills are still very powerful, but Sun Tu quickly discovered the problem.

What's special is that the magic stone has replaced the bullet, how to use this elemental ammunition, and I won't have to find a firearm that uses physical bullets.

"If you don't try to attach elements to the magic energy stone, if you can't do it, you can only find physical bullets and guns, and some gun shops in the city should still sell them." With the mentality of giving it a try, Sun Tu took a yellow-level magic energy stone, and then activated the skill element ammunition.

As a faint white light flashed, the magic energy stone in his hand turned pale blue, and the surface exuded a trace of coldness.

"It's done, I'm a genius." Looking at the magic energy stone in his hand, Sun Tu gave a thumbs up to his wit.

Next, he attached light, fire and darkness to the three yellow-level magic energy stones, and Sun Tu also thought about attaching two or more elements to a magic energy stone, but in the end he gave up this dangerous idea, what if the explosion killed and maimed the people around him.

In fact, what he is most worried about is his own life, after all, this is reality and not a game, and there is no such thing as a resurrection coin when he dies.

Loading a magic energy stone with an ice element attached to it into the assault rifle, Sun Tu aimed at the chest of a Xuan-level skeleton holding a bone axe in his hand, and gently pulled the trigger.

"Whew!" With the faint sound of gunshots, a light blue beam of light the thickness of a little finger shot out from the muzzle of the gun, spanning a distance of five hundred meters in less than a breath, and accurately hitting the skeleton's chest.

The beam of light exploded instantly, and the icy cold air took the chest as the origin, and quickly spread to the skeleton's whole body.

I saw that the skeleton's movement became slower and slower, and finally turned into an ice sculpture, and after about five seconds, the ice element dissipated, and the skeleton regained its mobility.

"The attack power of the ice bomb has been slightly reduced, and the freezing time is about five seconds." In order to verify the effect of the ice bomb on monsters of different levels, Sun Tu fired a shot at a yellow-level skeleton.

The effect was very ideal, only to see that the skeleton directly turned into an ice sculpture, and then Sun Tu remembered the hint of gaining experience points in his mind.

Obviously, the yellow-level skeleton was killed in seconds, although the power of the ice element ammunition has decreased, but the damage is not something that the yellow-level skeleton can not bear, and now that Sun Tu is already a yellow-level nine-star, he can almost be promoted to the Xuan level, and the power of the magic energy gun is linked to the strength of the user.

As Sun Tu's strength gets stronger and stronger, the power of the magic energy gun will become stronger and stronger, but now the most powerful magic energy gun is only at the heavenly level, and it is still in the testing stage, and it has not been officially put into use.

Sun Tu's strength is still low now, and he can still use ready-made firearms to exert his maximum power, but what about in the future?

At this stage, the speed of research and development of firearms will definitely not keep up with his growth rate, and his abilities are all in firearms, which may cause him problems in the future.

Sun Tu fired a few more shots to confirm the effect of the ice element ammunition, which can kill yellow-level skeletons in seconds, Xuan-level can freeze for about five seconds, and earth-level can only slow down for two seconds, as for the heaven-level because there are no experimental subjects, I don't know what effect it can cause for the time being, but Sun Tu can roughly guess that it should be useless.

After shooting the energy of the Ice Elemental Demon Energy Stone in one go, Sun Tu put the Fire Element Demon Energy Stone into the Demon Energy Gun, aiming at a yellow-level skeleton is a shot.

I saw that the skeleton was split in an instant, and several skeletons that were relatively close were affected by the explosion and were injured to varying degrees.

"Oh my boy, it's terrible! This is simply a replica of the grenade, but the range of the explosion is a little small, barely a group attack, and the effect against these cannon fodder gathered together to charge is not bad. Sun Tu fired three shots at the dense group of skeletons, and no less than ten kill prompts instantly sounded in his mind.

"Awesome, my brother! Your abilities combined with firearms aren't as lethal as Huang Ying's, but they're more than five times more frequent and shoot more skeletons than her. Li Dasheng, who was also shooting skeletons with a gun next to him, inadvertently saw Sun Tu's attack, and couldn't help but praise him.

"Brother praised, I can only bully those yellow-level skeletons, this trick will not work when encountering Xuan-level skeletons, by the way, brother, do you want to try it?" Sun Tu wanted to test the magic energy stone that was attached to the element, and whether others could use it.

"Of course I have to try, what should I do?" Li Dasheng instantly became interested.

Sun Tu picked up a magic energy stone and attached it to the fire element, then handed it to Li Dasheng, who looked expectant, and then said, "Try it, but I'm not sure if others can use it." ”

Li Dasheng took the magic energy stone that turned red, and some couldn't wait to load the magic energy gun, and pulled the trigger on the group of skeletons in the distance.

The cargo was fully automatic, and a series of beams erupted from the muzzle of the gun, and the group of skeletons in the distance instantly burst into flames, and the sound of dense explosions was endless.

"Cool, it's so cool, brother bring me a few more pieces." After shooting the energy in the magic stone in one go, Li Dasheng's face was full of excitement.

His marksmanship is not very good, a magic energy stone can kill ten skeletons is not bad, but using Sun Tu's magic energy stone with additional abilities, there is no need to aim at all, as long as the trigger is pulled on the skeleton group, and the efficiency is high, Li Dasheng roughly estimated that the magic energy stone killed at least sixty or seventy skeletons, this ability is simply a monster farming skill.

Now in the state of teamwork, although teammates can also get experience by killing monsters Sun Tu, although it is only one-tenth, but mosquito legs are also meat, teammates kill more skeletons, which means that he gets more experience, and even Sun Tu wants to provide fire element magic energy stones to several other teammates with low monster killing efficiency, and the idea of becoming a logistics staff himself.

But just think about it, the use of elemental ammunition consumes energy, and this energy is not like the ability to replenish it with magic stones, which can only be slowly recovered by itself.

Without saying a word, Sun Tu began to attach the fire element to the magic energy stone, and after consuming twenty-five points of energy, five fire element magic energy stones appeared in Sun Tu's hand.

After handing over the five Fire Elemental Magic Energy Stones to Li Dasheng, who was eager to try, and instructing him to use them leisurely, Sun Tu continued to test the other two Elemental Magic Energy Stones.

With the perfect cooperation of the skeleton brothers, Sun Tu successfully completed the test, and the result made Sun Tu very satisfied, and the terrifying penetration of the light element beam allowed Sun Tu to successfully complete the first kill at the prefecture level, although it was only a star at the ground level.

A prefecture-level star is also a prefecture-level, isn't it?

Although the attack power of the dark element beam is not high, Sun Tu used the Demon Hunter anti-equipment sniper rifle with the light element to successfully win the second kill of the ground level, but this time the kill was a three-star ground level, don't look at it is just two more stars, but the defense is stronger to a higher level.

The Demon Hunter Sniper Rifle is a heavy firearm, and it has a passive skill heavy firearm mastery bonus, which can kill and shatter the skull of a ground-level three-star skeleton warrior.
