"It seems that I don't need this thunder for the time being. ”

Zhao Yuan sighed, the huge gap between reality and imagination made him very shocked.

Although the information leaf said that the strength of Lei Mang will increase with the improvement of cultivation and the increase of Qi and Will. But judging from the current situation, it is estimated that for a long time in the future, it is impossible to expect Lei Mang to come in handy.

Instead of poking people with charged fingers, it is better to use the Wind Thunder Whip and Thunder Light Talisman. At least the power of thunder and lightning brought by these two is far stronger than that of Thundermang.

Just when Zhao Yuan was about to put away Lei Mang, he suddenly thought of a use that Lei Mang could play at the moment - an electric needle.

The so-called electroacupuncture is a technique developed by modern acupuncture, in which a small amount of electric current is applied to the silver needles when they are left at the meridian acupuncture points, so as to produce continuous stimulation, thereby improving the therapeutic effect.

It is impossible to carry the electroacupuncture device on the body at any time, and even if you do, it is impossible to find the power supply anytime and anywhere.

Lei Mang is very weak now, and he can't play a role in the enemy, so it seems that it is not bad to use acupuncture and moxibustion to play the role of an electric acupuncture.

At least it can do something.

With an idea, Zhao Yuan immediately planned to try it in practice.

He opened the space of the ring, took out a silver needle from it, and pinched it between his right fingers.

As soon as the fingers were closed, the weak Lei Mang was hidden, and it was difficult for others to find it. And the thunder and lightning were also covered with silver needles in an instant.

Electroacupuncture uses a small amount of electric current. However, although Lei Mang is small, Zhao Yuan can control it freely. Immediately, he reduced the intensity of the thunder and lightning to a suitable level, and then used himself as a test, and pierced this electrified silver needle into the Neiguan acupoint in his left hand.

A tingling sensation of current stimulation immediately appeared in the acupuncture points, and quickly flowed along the hand and yin pericardial meridian where the Neiguan acupoint was located, which soon made every acupoint on this meridian have an obvious sense of current stimulation.

"Yes, after the thunder and lightning, the effect of acupuncture has improved a lot. I guess it's much better than ordinary electroacupuncture. ”

For the experimental results, Zhao Yuan is quite satisfied. At least it proves that Raymang can still be of some use at the moment, and it will not be completely idle.

Picking up the silver needle, Zhao Yuan opened the ring space, ready to put it in.

But just as he let go of his fingers, the silver needle suddenly 'swished' and flew out.

Although he didn't fly far before falling to the ground, this still surprised Zhao Yuanda.

"What's the situation?Why did the silver needle fly out on its own just now?" A big question mark appeared in Zhao Yuan's mind.

He put away Lei Mang, took a step, squatted down, picked up the silver needle from the ground, and tried a few more times, but this time the silver needle did not fly out of his hand.

"Why don't you fly now?" Wait, could it be that Lei Mang caused it?" Zhao Yuan reacted suddenly, and hurriedly cast Lei Mang again, wanting to verify his guess.

Flashing lightning wrapped around his index and middle fingers.

When he let go of his fingers, the silver needle really 'swished' and flew out again! And because he didn't reduce the strength of Lei Mang this time, the speed and distance of the silver needle flying out were not comparable to the previous time!

Zhao Yuan clearly heard the two muffled sounds of 'dang' and 'dang', and the silver needle that flew out actually penetrated a big tree in front of him, and then he was exhausted and nailed to the second tree.

You know, the trees in this forest are not the bowl-thick trees in the city. The smallest tree here also has to be held by a person with open arms, which shows how thick it is. But the slender silver needles pierced through the thick trunk of the tree. This power, this power, is simply terrifying!

It's strange if you shoot on a person and don't get pierced!

"Sure enough, it was caused by Lei Mang, but why did this phenomenon occur?"

After Zhao Yuan was surprised by the power, he began to ponder the reason for this phenomenon again.

He then experimented several times, and finally determined that if he only attached Lei Mang to the silver needle, this phenomenon would not occur. Only when the silver needle is in the wave of thunder and lightning between two fingers will it fly out like a bullet!

Zhao Yuan wanted to break his head, but he couldn't think of a reason. But it doesn't matter, there are also the Internet and search engines.

Looking for a place with a better signal, Zhao Yuan opened the browser in his mobile phone, typed relevant information in the search engine, and after some searching, he really found the answer.

"It turned out to be the principle of the electromagnetic cannon!" Zhao Yuan suddenly realized, and said: "The electric current between my two fingers formed an electromagnetic field, and when the silver needle passed through it, it was accelerated by the magnetic force, so it shot out with the momentum of thunder! In other words, under the action of Lei Mang, my finger became a simple version of the electromagnetic cannon, and the silver needle was the cannonball fired!"

After figuring out the reason, Zhao Yuan became excited: "I thought that Lei Mang could only be used to treat diseases for the time being, but I didn't expect that it could also come in handy in actual combat! The silver needle it shoots is far more powerful than an ordinary pistol." The most important thing is that it is very hidden, and it can launch an attack without the enemy noticing it at all, which is simply a secret weapon that blows up the sky!"

After many drills, Zhao Yuan also found a lot of problems.

Sometimes, even if the silver needle is between two fingers, it will not be activated. According to Zhao Yuan's speculation, this should be caused by the magnetic field generated by the current not meeting the standard. And sometimes, although the silver needle was stimulated, the direction was 108,000 miles away from what Zhao Yuan wanted......

Although there were many problems, Zhao Yuan was not discouraged, but was motivated.

Because he knows that these problems can be corrected in experiments and exercises again and again. In the end, he will definitely be able to thoroughly understand the electromagnetic cannon technology. At that time, he will be able to activate the silver needle as he pleases, pointing and hitting wherever he wants.

Fortunately, excitement is excitement, Zhao Yuan did not forget the business, and continued to check the harvest.

In the Danfang column, Zhao Yuan saw a new recipe - Jingqi Pill.

The effect of this pill is simple, but it is very important.

It is able to inhale the Qi into the body, remove the turnips, and throw away impurities to leave the essence.

"What a Purifying Qi Pill, with it, although it can't speed up the progress of cultivation, it can make cultivation more solid, make the foundation more solid, and greatly reduce the chance of going mad!"

Zhao Yuan continued to rummage through the information leaf, but he couldn't find anything new. However, this harvest has made him very satisfied.

"Sure enough, the improvement of the realm has brought the greatest harvest, and today is really a bumper harvest!"
