But suffering from the fact that there was no gunpowder in this world, Wang Lin thought of a fireball spell that was similar to the nature of gunpowder. Pen Fun Pavilion wWw. ｂiquge。 info is also a natural acquaintance between two substances that rely on explosions and heat to vent energy, which makes Wang Lin see the hope of replacing gunpowder with fireballs, and spell mines are one of the successful attempts. But it's not complete, it's just a preliminary verification that the principle of using the rune seal can passively trigger the rune seal without human intervention, and achieve the same effect as a mine, but it should be in a hurry, and there is still a lot of room for improvement in many details.

This time, the bazooka is another attempt, and this time it is the same idea as the spell mine, not sticking to the traditional gunpowder weapon method. For example, because the rockets on the earth are driven by gunpowder, there must be a steel one used to compress the gunpowder to produce an explosion, but the fireball is naturally explosive, and there is no need to wrap the steel at all, of course, the power of gunpowder is not large, so the main killing method of various shells is actually the hard warhead fragments pushed by high-temperature gas after the gunpowder explosion.

And the fireball technique relies on explosion and heat to achieve the purpose of killing, a bit similar to the killing method of explosives on the earth, not to mention the size of this power, it is a good weapon to hit the target, you must know that this world is a high-martial world, the cultivation civilization of the extremely developed body, this nerve reaction speed is not to say, the earth's general artillery can not hit them, the only effective way is the energy weapon This kind of attack is close to the speed of light.

Wang Lin plans to make an otherworldly version of an RPG that uses the principle of bazooka.

The idea was there a long time ago, and Wang Lin now wants to turn this idea into a practical weapon.

Before the experiment began, he had to verify the principle, Wang Lin first asked people to find a large piece of dark iron, made a hollow iron bucket, and placed it on an uninhabited slope in the back mountain as a weapon test site. Arrange the black iron barrel and face the far away, this thing looks like an old-fashioned mid-world black powder cannon, and the short and thick barrel has a strong rustic atmosphere. Fortunately, this is just a technical verification test prop, if the finished product also looks like this, then his old face will be lost to the other world.

Wang Lin installed a mana generator directly removed from the spell mine at the bottom of the iron barrel in advance, put a talisman seal into the launch box, and let Yu Nian and others, who were watching the excitement, stay away, and took out a pull wire from the small hole reserved behind the black iron barrel, and after seeing that everything was adjusted, as soon as he pulled the rope, he began to observe the launch, only to see a red light suddenly appear from the reserved muzzle in front of the iron barrel, shooting straight into the distance. Then came a low explosion, a blast characteristic of fireballs.

Wang Lin hurriedly checked the effect and recorded the experimental data. Once measured, this spell firing range is determined. In order to obtain more objective and real data, Wang Lin conducted ten experiments in a row. All of them have obtained similar results, and in general, the fireball technique that has been compressed by the iron pipe has been significantly improved because the escape of energy has been greatly reduced, so the range has been significantly improved. For example, the range of an ordinary fireball technique is between fifty and one hundred and fifty meters, but after being compressed by the iron bucket, the range is at least doubled, reaching a distance of one hundred to three hundred meters. Beyond this distance, the fireball technique will dissipate, so the effective range is about 200 meters. Of course, this is just the original data, Wang Lin used a barely processed dark iron cylinder as the emitter to get this data, and then carefully designed a scientific shape, so there is still a lot of room for improvement in this range. Besides, this range also has a lot to do with the length of the iron pipe, but Wang Lin's purpose is to make a shoulder-mounted bazooka, in order to facilitate use and carrying, this body tube cannot be too long, and this iron pipe is the length and size designed by Wang Lin that is most in line with the proportion of the human body. This drastically reduces the amount of work to be tested.

This test not only obtained the range, looking at the cracked ground behind the iron pipe, Wang Lin also had an intuitive understanding of the recoil after the iron bucket fired the fireball, and fortunately the recoil of firing spells was much smaller than that of firing gunpowder weapons. This provides a reference for the design of the subsequent seismic relief device.

Originally, when he heard that Wang Lin was going to experiment with a new magic weapon, several major figures on the island were busy watching it, but in addition to moving an iron pipe, Wang Lin threw precious talismans in the iron pot and blew them up. Even Yu Nian, a housekeeper who has seen the world, can't stand Wang Lin's waste. After he couldn't stand it, he carefully put forward his opinion to Wang Lin, but he replied euphemistically that this is a necessary investment in the research and development of new weapons, and this is just that, this is just the beginning, and the big head is behind.

There is no way to do it for more than a year, and besides, Wang Lin is the owner, he can't persuade him, so he has to leave first, and come out of sight. The people around can't stand it, you must know that a talisman seal is worth 5 spirit stones, which is a captain's salary for a month. And Wang Lin didn't blink his eyes and threw 10 talismans into an iron bucket, which were worth 50 spirit stones.

In addition to lamenting that Wang Lin is really a loser, they are more confident in this big boss, what are they afraid of with such a rich boss. Only Pei Fan looked at Wang Lin's experiment thoughtfully. Ignoring these people's ideas, Wang Lin began to conduct the next experiment after testing the range ---- destructive power.

The most basic thing about a weapon is how powerful it is. This time, Wang Lin simply moved the iron bucket to the bottom of a cliff, and after reserving about 200 meters, he began to bombard the rock wall with the iron bucket to observe the killing effect on the hard rock wall. In order to better compare with the original fireball technique, Wang Lin also specially played a few uncompressed fireball spells fired by Fu Seal next to him for comparison.

The results of the test were gratifying, after the compression of the iron bucket, a part of the escaped energy was fully utilized, which not only increased the range, but also increased the power. This small iron bucket made an ordinary fireball technique twice as powerful, and the pressure of the launch after such a compression was greatly increased. The weakness of the slow speed of the fireball spell has also been overcome, and the fireball that reaches twice the normal speed is no worse than the speed of any high-speed spell.

This series of tests has achieved the desired effect perfectly.
