Richard left and headed straight north, eventually arriving at a small town called "Linghua Town" before dark.

In the town's inn, Richard paid two silver coins, had a good dinner, and got a good room.

But when the night got dark, Richard didn't rush to rest, but studied something in the room.

It is the topic that I have been thinking about all along: the storage technology of free energy elements.

This technology traces back to its origin, and it was obtained from the treasure of the Black Spirit King, although the treasure of the Black Spirit King was completely cracked on the East Coast, the related technology in it has been digested to this day.

And the purpose of his research on this technology is not to make more and larger energy storage containers for free energy elements. In his opinion, with the mask of the Black Spirit King and the short staff of energy storage, the demand is almost satisfied.

The purpose of his research on this technology is to try to miniaturize, independent and automate energy storage containers.

The reason for this is to better deal with the powerful wizard threat of the main continent.

He now deals with wizards in two main ways. One is the Gloves of the Destroyer, and the other is the Spell Bullet Shot.

The glove of destroying the world is powerful, and third-level wizards can kill it in seconds, but the disadvantage is also obvious, that is, it consumes too much energy and is difficult to use as a regular means of combat.

In comparison, Spell Bullet Shot is more flexible against normal enemies than the World-Destroying Gauntlet. It can burst out with powerful destructive power in a short period of time, successfully killing enemies without much defense, consumes less energy, and is easy to use.

However, spell bullets also have drawbacks that cannot be ignored, mainly reflected in the fact that the applicable environment has certain restrictions and the play is unstable.

Spell bullet shooting, in a relatively confined and small space, is very effective against unsuspecting, undodging enemies. However, in relatively open areas, the effectiveness of defending enemies who are always ready to dodge will plummet.

This is mainly due to the fact that once the wizard has fully deployed his speed and constantly shifting positions, it will be difficult for the spell bullets to lock onto the opponent. If there is not one, but two, or more wizards, it is even more difficult to lock.

To solve this problem, he had an idea.

That is, transform the spell bullet so that the spell bullet has a certain spell effect and produces stronger destructive power. The most important thing is that the spell bullet can actively track the enemy to a certain extent through the effect of the magic pattern, lock on to the target by itself, and complete the attack.

In other words, it is to transform the spell bullet into a miniature spell homing missile.

It's not easy, if not difficult, to get there.

Just in front of you, you have to solve many difficulties such as material selection, wind spell cracking, tracking lock, and power increase.

Of course, the storage technology of free energy elements must be overcome.

He didn't want to have to charge the miniature spell homing missiles one by one and activate the many magic patterns on them one by one every time he fought.

If that's the case, it's better to keep using spell bullets or the gloves of the world.

What he wants is to make the miniature spell homing missile achieve a certain degree of intelligence, and become an intelligent attack spell prop, as long as it is taken out, it can be used directly and exert its effect.

If he can do this, then he can be fearless of most wizards in the main continent, and he will not be afraid of fighting a war of attrition.

And if he really did it, for him, it did not mean the end, but only a stage in a huge plan.

Based on the knowledge he had gained from the Black Spirit King's treasure, he already had a relatively complete and huge plan for future development.

When the miniature spell-seeking missile is successfully developed, the huge plan is launched, and he will use a crushing way to fight the wizards of the current world.

This crushing is not in strength, but in combat thinking, and it will crush an entire latitude.

And he is also preparing to use this way, through a huge plan, to analyze the truth of the world more deeply, and finally try to get closer to his ultimate goal: to figure out what is going on in this world.

Of course, for now, we still have to start from the beginning, starting from the basics.

So......

......

In the hotel room, Richard sat at a wooden table, his eyes looking at the air in the room, and with a flick of his fingers, a wind spell was released.

"Whew!"

The air in the room flows in a particular direction, increasing at a faster speed, eventually forming a strong wind.

In this strong wind, Richard sat quietly, and with a flip of his hand, a small shellless spell bullet appeared in his hand, which was lifted up with the nail of his middle finger and blown in the wind.

The caseless bullet could be seen shaking as if it had been blown away at any moment, but there seemed to be a mysterious force on the nail that bound it, making it impossible to leave the fingertip.

Richard stared at the shellless spell bullet, looking at it carefully, thinking as he watched.

This is his simulated wind tunnel experiment.

That is, he is studying the effect of gas flow on caseless spell bullets.

Generally speaking, this kind of wind tunnel experiment is tested in a specially made wind tunnel, where object models are placed, and the most widely used are aircraft, such as rockets, airplanes, etc.

This is a very important link in the development of new rockets and aircraft. Therefore, at the end of World War II, in order to seize Germany's large wind tunnel and obtain the technology in it, France almost met with the United States.

What Richard is doing now naturally can't be compared with the real wind tunnel test on the earth, just using wind spells to simulate a rough idea. Because he currently has only one idea for the production of miniature spell tracking missiles, and he has not yet finalized it, simulating wind tunnel tests, just to expand his thinking.

In this way, Richard looked at the shellless spell bullets in the strong wind and kept thinking.

The shellless spell bullet on the fingertip began to change little by little in his mind, increasing in size, becoming longer and thicker, and the whole was like an arrow, and many magic patterns appeared on the surface......

After a long time, Richard put away the shellless spell bullet on his fingernails, and gently placed his hand on the table, and the strong wind in the room slowly stopped.

His lips pursed slightly, and after a while, he opened and closed his voice: "The volume must be increased, the spell pattern needs multiple, the wind spell is used to control the flight, and the special spell is needed to lock the target and adjust the attitude." After a successful hit, the warhead will burst out with more power than the improved 315 alloy. These must be supported by free energy elements, so the storage technology of free energy elements must meet the following points:

The first is stability, which must ensure that there will be no spontaneous leakage, the second is controllability, which can be released under specific stimuli, and the third is ......"

As he was talking to himself, the idea of making a mass of energy storage containers flashed through Richard's mind.
