Douluo: This soul master is too mediocre

Chapter 92 Spotlight Astigmatism
After a quarrel, Ning Yu continued to practice the sun exercise technique.

Because of his physical fitness, his ability to withstand the burning sensation far exceeds that of his friends.

It was hard for Ning Kun and the others to bear it now, but the scorching sensation produced by practicing the sun body training technique at this time was still within Ning Yu's tolerance.

However, Ning Yu began to think about it while practicing the Sun Exercise.

When the sun just rises in the morning, due to the insufficient sunlight intensity, the efficiency of practicing the sun body training technique is very low.And when it was approaching noon and the sun was high, the scorching sensation of practicing the sun body training technique was unbearable.

The situation in the afternoon is similar, but in reverse.

It can be said that there is not much time in a day that is suitable for him to practice the sun exercise technique, let alone Ning Kun and others who are weaker than him in physical fitness and endurance.

Suddenly, Ning Yu thought of a magnifying glass.

A magnifying glass is a convex lens that has the effect of converging light.

When the sun is just rising in the morning and the sun is about to set in the evening, due to the lack of sunlight, the efficiency of practicing the sun exercise is not high.

If a large convex lens is used to gather the sun's rays, wouldn't it be possible to improve the efficiency of cultivation in these two time periods?
In addition, the convex lens can gather the sun's rays, and the concave lens, on the contrary, naturally also has the effect of distributing the sun's rays.

Isn't the midday and afternoon sun too strong?Get a large concave lens to radiate the sun's rays, wouldn't it be possible to practice during this time?

Well, it's best to have a convex lens that can be adjusted freely, a convex lens that gathers the intensity of the sun's rays, and a concave lens that emits the intensity, so that the intensity of the sun's rays throughout the day can reach the most suitable range for one's own cultivation.

If this method is feasible, then when absorbing moonlight at night to practice Taiyin Soul Art, you can also use the two lenses to achieve the highest cultivation efficiency.

Thinking of this, Ning Yu couldn't help praising himself for his cleverness.

After Ning Yu talked to Ning Fengzhi about the auxiliary effect of the concave-convex lens, Ning Fengzhi immediately arranged for people to build it.

The efficiency of the Seven Treasure Glazed Tile Sect was not slow. Three days later, ten thick metal pillars were erected in the peach forest of the Taohuayuan.

A large lens with a diameter of more than five meters is installed on the top of each metal pillar, and there are three movable wheels at the bottom of the pillar.

Convex lenses capable of concentrating light are installed on the top of five pillars, and concave lenses capable of astigmatism are installed on the top of five pillars.

"Ayu, how do you use this thing?"

Glancing at the sun that had just risen in the sky, Ning Kun pointed to the metal pillar with a large convex lens in front of him, and asked Ning Yu.

Hearing this, the three of Ning Rongrong beside him also looked at Ning Yu.

"Turn the bottom wheel to adjust the height of the lens. Turn the middle wheel to adjust the direction of the lens and point it to the sun. Turn the top wheel to adjust the angle of the lens."

Ning Yu personally gave a demonstration to several friends.

This pillar is equipped with a convex lens. Under Ning Yu's adjustment, the convex lens gathers the light and forms an oval light spot of more than one meter on the ground.

Afterwards, Ning Yu told several people: "Pay attention, this mirror has a strong light-gathering ability, don't adjust it too high at the beginning, or don't cry if you get burned!"

"Cut~, I will be burned and cry? It doesn't exist!"

Hearing this, Ning Kun immediately curled his lips in disdain.

joke!I, Liangkun, haven't cried once since the awakening of Wuhun!
"Really? I hope you can be so brave later!"

Ning Yu took a deep look at him, then pulled the blue silver grass from the ground not far away, and then turned the wheel on the metal pillar to directly adjust the light gathering ability of the convex lens to the strongest.

Blue Silver Grass: Is this a human thing?

Soon, a small dazzling light spot less than one centimeter in diameter shone on the floor tiles around the bottom of the metal pillar.

"Kun Zai, keep your eyes open!"

As he spoke, Ning Yu handed the Blue Silver Grass in his hand to the small light spot on the floor tile.

In an instant, a trace of white smoke rose, and the fresh blue silver grass in Ning Yu's hand ignited spontaneously without fire.

"hiss--!"

Looking at the scene in front of them, the friends couldn't help but gasp.

Especially Ning Kun, his two calves couldn't help trembling, and the newly pulled blue silver grass could be ignited, so wouldn't his small body be roasted?

"Haha, don't worry, as long as you don't kill yourself, this thing is quite safe."

Seeing Ning Kun whose calves were trembling, Ning Yu was happy.

Don't think that the convex lens can ignite the blue silver grass, but in normal use, basically this will not happen.

If the human naked eye can perceive the temperature change, it can be found that the area where the convex lens focuses light and can produce temperature changes actually presents a cone.

The highest temperature is undoubtedly the apex of the cone, which is where the floor tiles are now.

But once a person stands on it, the position where the human body touches the focused light is no longer the apex of the cone, but the middle position near the apex of the cone. Naturally, the temperature at this position will not be too high.

Half an hour later, under Ning Yu's hands-on teaching, the four of them learned how to adjust the lens so that the sun's rays gathered were at the most suitable intensity for their own cultivation.

The soul power in the body operates according to the specific route of the sun body training technique, and Ning Yu's body greedily absorbs the sun's rays gathered through the convex lens.

"Not bad."

Feeling the burning sensation in his body that was within his tolerance, Ning Yu nodded in satisfaction.

When practicing Sun Exercise, the burning sensation is unavoidable. After all, without this burning sensation, it means that it is just a lonely practice.

The burning sensation is indeed unavoidable, but whether you can bear it or not makes a big difference here.

If you can bear it, the burning sensation is actually quite comfortable, just like taking a sauna.

But if you can't bear it, then it's really 'people are suffering in hell', which Ning Yu has experienced personally.

"Unfortunately, this thing is not smart enough, and it needs to be readjusted every once in a while."

Glancing at the 'training aid' in front of him, Ning Yu secretly thought of it with some regret.

The position of the sun and the intensity of light are not static.

The position and light intensity of the sun have changed, so if you want to achieve the highest efficiency in practicing sun body training, you must adjust the position and angle of the convex lens at regular intervals.

But Ning Yu couldn't force too much.

After all, if you want to do this, you have to either come up with a machine spirit or a numerical control computer.

In contrast, Ning Yu estimated that it would be easier for him to become a god at level [-].

As time went by, the temperature of the sunlight gradually increased, and several friends gradually abandoned the practice of concentrating light with a convex lens, and began to practice astigmatism with a concave lens.

As for Ning Yu, his physical fitness is much stronger than the others, and he still needs to focus on training for the time being.

In the evening, Ning Yu was quickly scraping the food in the bowl, thinking about going to the Taohuayuan to practice Xiantian Meditation and Taiyin Soul Refining Art after eating early.

At this time, Ning Fulong said: "Xiaoyu, it's not a big deal for you to practice all day long. Tomorrow is the day when the royal prince Xue Qinghe officially worships the suzerain as his master. The apprentice banquet will be held in Tiandou Palace. How about I take you there to play?" Play?"

During this period of time, Ning Yu was 'addicted' to cultivation all day long, and Ning Fulong naturally noticed it.

Serious cultivation is a good thing, but for a seven-year-old child, it is not a good thing to indulge in cultivation all day long.

In Ning Fulong's view, children have to play and play, and they can't be like a boring gourd, otherwise they will easily develop an introverted personality and fear socializing in the future.

"Qian Renxue's apprenticeship?" '

Ning Yu was stunned, that's right, in the original book, Qian Renxue's disguised Xue Qinghe is Ning Fengzhi's apprentice.

It's just that perhaps due to the influence of his little butterfly, the matter of apprenticeship has come a lot earlier.

"I'm going, I'm going!"

Before Ning Yu could answer, Xiao Wu beside her said excitedly.

God is pitiful, the rabbit's nature is lively and active, but after joining the Seven Treasure Glazed Tile School, Xiao Wu has never left the school for even half a step.

When she was studying in the Zongmen Academy, she still had many playmates, but since Zongmen acquired the Sun Body Training Technique and Taiyin Soul Refining Art, she has no time to go to the school to dawdle, so she has to spend her daily playing time. The time spent in trouble is used for cultivation.

There is no way, these two cultivation methods are too delicious, even if she is usually playful, she can't resist the temptation to improve her physical fitness and mental strength.

After all, Xiao Wu has not forgotten that she is still responsible for killing her mother!

"Xiao Wu, you can't go, stay in the sect obediently!"

Ning Fulong shook his head and directly vetoed it.

Just kidding, Prince Xue Qinghe's teacher apprentice banquet, the royal family's Green Eagle Douluo and Dugu Bo will definitely be there, how can Xiao Wu, a transformed 10-year-old rabbit, appear under their noses?
What's more, apart from these two Titled Douluo, important officials from both the military and political sides of the Heaven Dou Empire will also be present. Among these people, there are many eight-ringed Soul Douluo masters.

Especially those marshals and legion commanders of the Tiandou military, all of them must have a soul power level above level 80, otherwise if they are not strong enough, they will not be able to convince the masses in the army.

"Ah~, I can't go!"

The pair of rabbit ears on the top of Xiao Wu's head drooped immediately, her face was full of displeasure.

But Xiao Wu can also understand, after all, there are too many masters who can see through her identity at Prince Tiandou's apprentice banquet tomorrow.

And it hasn't been long since she got the soul power control method, she is still far away from being able to change her breath!
"Xiao Yu, are you going?"

Ning Fulong turned his head to look at Ning Yu.

"go with!"

Ning Yu nodded.

If the apprentice was someone else, then Ning Yu would not be bothered to go, but who would let Miss Angel be the apprentice tomorrow?
Well, give Ms. Angel a face!
Qian Renxue: he~, tui!Miss Ben doesn't care about your face!
