In the early morning, two small electric donkeys ran briskly on the road outside Soto, and the singing from the car showed that the cyclist was in a good mood. Next to the two small electric donkeys is a large, white short-haired dog with yellow round spots on its back.

This familiar team of two people and one dog is none other than the Oscar and Oschin brothers who have finished their autumn vacation, and Cowan, who has been promoted to a hundred-year-old soul beast.

In the past autumn vacation, Oscar and Oschin not only successfully completed the goal of breaking through level 20 of soul power, but also worked together to make two very interesting soul guides.

Now these two soul guides are stored in the backpack-type storage soul guides behind the two of them that are made of empty dark iron as the core magic circle, ready to go to the academy to test them.

Here's the thing, after the holiday, Oschin estimated his soul power improvement speed, and found that if there was no accident, there would be no problem in completing the set goal, so he began to plan for himself to design the next stage of the soul guide armor.

In the process of designing, Oschin's idea was to make a pair of two-armed soul guide armor that could link the fist armor and the cuirass, and install soul guides that could provide long-range coverage fire on the two-arm armor to increase his fire coverage area and enhance the fire blockade effect.

As a result, when I was rummaging through the omniscient library for information on suitable weapons, I accidentally found a plan for the production of a Gauss sniper rifle.

The moment he saw the design drawing, Oschin's brain was like a lightning bolt, and he found that he had gone into a misunderstanding when he changed the weapons of his previous life.

It has always focused on traditional gunpowder weapons, subconsciously ignoring those energy weapons that are still conceptual designs.

After secretly scolding "empiricism is not shallow", Oschin began to focus on these energy weapons.

After all, this is the Douluo Continent, and the performance of the materials is largely beyond that of the previous life, and many soul guides are essentially energy weapons that use soul power as a means of attack.

With these prerequisites in place, Oschin was pleased to find that high-powered weapons such as Gauss sniper rifles, electromagnetic guns, railguns, and plasma weapons could be crafted, while laser weapons were simply soul guide ray weapons.

It can be said that at this stage, it is more convenient to make these energy weapons than to change those gunpowder weapons.

After all, most gunpowder weapons exist as custom-built soul guides after the demon modification, and they rely on a large number of expensive bullets or cannonballs to cause damage.

After repeatedly comparing the difficulty of crafting the above-mentioned energy weapons, Oschin's eyes were on the electromagnetic cannon with the simplest principle and the ability to appropriately enlarge the volume to reduce the difficulty of crafting.

In terms of usage, the electromagnetic cannon also consumes shells, so it should be classified as a fixed soul guide.

However, if you look closely at the working principle of the electromagnetic gun, it is not difficult to find that the reason why the electromagnetic gun is so lethal is because it produces a sufficiently strong ampere force through the electromagnetic effect inside the barrel,

These amperes accelerate the pure metal shell, so that the metal cannonball has a terrifying kinetic impact that can tear everything apart after it bursts out of the barrel, and the range far exceeds that of traditional gunpowder weapons.

To put it simply, it is the barrel that determines the power of the electromagnetic cannon, and as for the shell, as long as it is pure metal.

Therefore, the electromagnetic cannon is not a fixed soul guide that relies on the power of cannonballs in the general sense, and the use of electromagnetic cannons does not need to worry too much about the consumption of cannonballs.

As long as you can make a launcher that is not particularly large, can make the cannonball gain enough kinetic energy and can be reused, the electromagnetic cannon is considered to be completed.

Since the design drawings given in the omniscient library are within the scope of Oschin's current production capacity, Oschin pulled his brother Oscar and began to build this cannon barrel, and with the blessing of a large number of rare metals, the production of this cannon barrel is quite smooth.

In view of this, Oschin also put a little effort into the production of cannonballs.

It is a simple inscription on the shell that allows it to continue to accelerate for a period of time after being discharged.

Add to that a blasting circle that explodes two seconds after the obstacle stops, and this makes it easy to make the cannon even more powerful.

In the end, Oscar and Oschin made a three-meter-long barrel, the front half of which rests on a triangular stand, and the second half is wrapped in a thick base one meter wide, one and a half meters long, and one meter high.

To sum up, the total length of this electromagnetic cannon is four and a half meters, and the highest point is one and a half meters, which can usually be divided into three parts: the bracket, the base, and the barrel.

Normally, when using this electromagnetic cannon, you need to assemble the three, but if the user's soul power is enough and can carry a three-meter barrel, you can also carry it yourself as a large RPG.

Now this big killer weapon is on Oscar's back, and it is specially made for it to use the Void Iron as the core magic circle, and it is made in a secondary storage backpack containing ten cubic meters of space.

After all, the volume of this thing is still a little too large, and if it is placed in the usual storage soul guide, it can take up half of the space, which is not suitable.

The Railgun was the first large soul guide the brothers made during the holidays, and the second was in the backpack behind Oschin, a week before school started.

At that time, the brothers had already broken through the bottleneck of level 20 and were preparing for their trip to the Star Dou Great Forest. In order to make his stay in the forest more comfortable, Oschin began to look through the information again, and it turned out that he really found a good thing:

How to make metal foam. It is said to be metal, but in fact foam metal is a special kind of soul guide.

Normally, the metal foam can be shrunk together to look like a piece of ordinary metal, but when you input soul power, the metal foam expands to form a space that is set in shape when you make it.

Typically, a volume of one cubic meter of foam metal expands to form a space of ten cubic meters.

Of course, the foamed metal is not a storage soul guide, this space is the space created after its own expansion, and this space does not exist after shrinking, so if you want to achieve the normal scaling function, you can't store foreign things in this space.

Speaking of which, everyone should be able to react, this is completely able to make a camping house for themselves and take it with you, tables, chairs, benches, including beds, can be set to form foam metal extensions when making.

Some other things have storage soul guides anyway, and when the house is opened, they can be put in and taken back when they shrink, and there are not many things that need to be used for a night or two in the wilderness.

Oschin made himself a shrinking three-cubicle of foamed metal, which expands to form a T-shaped hut that rises one and a half meters above the ground.

The short side of the T-shaped is divided into two parts, and the first half is a small lounge where you can make something hot to eat.

As long as the matching soul guide is made in advance, the night vigil can stay in the house and watch the detection screen of the soul guide arranged around the hut through the soul guide display.

The back half of the short side is a small bathroom and toilet, as long as the soul water heater is installed at that time, you can take a hot bath with plenty of clean water.

The long side of the T-shape, the layout is very similar to the soft sleeper car of the train, a narrow corridor plus a small bedroom with a door, a small bedroom is two bunk beds, can live four people, a total of three small bedrooms.

After having this thing, not to mention the next trip to the Star Dou Great Forest, you will definitely be able to rest better, but Oschin has not yet finished making the supporting facilities.

The missing parts are the trigger-type defensive soul guides that are to be installed on the exterior wall of the house and the probing soul guides that are arranged around them.

For these two parts, Ostin is going to ask the teacher Shao Xin to help him make a soul guide of at least level four, and then he will find a seventh-level bottle soul guide full of soul power from the teacher and connect it to the hut as an energy source, which is proper.

In this way, with a relaxed attitude, the two of them returned to Shrek Academy on time twenty minutes later, that is, at half past six in the morning, after a six-week absence.

It was still early, and the teachers were doing their own things in their own rooms, and they didn't meet any of the teachers along the way, Oscar and Oschin came to the dormitory, and then they stopped at the same time.

Next to the dormitory of the two of them, the wooden house dormitory, which was still in its original dilapidated appearance before the holiday, has obviously been repaired now, which is not good, but it is already enough to live in.

The most important thing is that whether it is from the fluctuations of soul power in the air that he perceives or Cowen's constantly shuffling nose, it can prove that there are already people living in this room.

The link to the heart was opened instantly: "The academy has recruited new students, and we finally have classmates?"

This was the first reaction of Oschin and Oscar after a moment of sluggishness, and the second reaction was, "The degree of fluctuation of this soul power should be less than that of a soul warrior with a tenth-level soul power, so the dean even went to earn a commission for helping people awaken martial souls!"

After cutting off the spiritual link, Oschin suddenly reacted, this new student should be the little fat man Ma Hongjun who has the evil fire phoenix martial spirit.

Since he had been in this world for a long time, some of the things that had existed in Oschin's memory had gradually become blurred.

Oschin didn't react to who it was at the first time just now, but fortunately he didn't react, otherwise Oscar would have sensed it.

Since the other party was meditating, Oscar and Oschin didn't bother each other, anyway, in the same academy, they should be able to get to know each other when they go to class later.

It's just that Oscar and Oschin, who still have too little experience in cultivating meditation for soul masters, didn't expect that normal meditation could produce such a large fluctuation of soul power, which people could clearly feel when they stood outside the house.
