Soon more than a month passed, and during this more than a month, everything was calm.

The eldest prince William continued to save money, King Donus was still seriously ill, and Richard was constantly studying the spells in the Monroe Chapter.

After a period of research, Richard finally learned several low-level spells of the Zero Ring in addition to the "Phosphorus Candle": they are Fire Impact, Water Droplet Condensation, Wind Barrier, Wind Knockback, Wind Lightness, and Wind Brute Force.

Fire Blast, emitting a cloud of flame that strikes your enemies, dealing damage. Richard tested it, and the power was almost like a sudden burst of fire in a stir-fry iron pot. If you hit someone, you can indeed cause some burns, but you can't kill a person.

After all, the Zero Ring low-level spells are really similar to tricks, and their power is often on the weak side. The biggest effect is not to hurt, but to cause panic. In the current era, the shock in the hearts of ordinary people when they see a flame suddenly growing in someone's hand should be no less than that of people on modern Earth when they see someone pulling out a firearm.

Water droplets condense, collect moisture in the air, and grow droplets around them. To put it simply, it is similar to small-scale low-level artificial rainfall, or water vapor liquefaction. If combined with the "Flame Blast" above, it is enough to solve the problem of lighting fire and drinking water when living in the wild, and as for the attack power - sorry, no.

The barrier of the wind, the repulsion of the wind, the lightness of the wind, and the brute force of the wind, all four spells come from the same source. Like, Fire Blasting is a fire-based spell, Water Droplet Condensation is a water-based spell, and all four of these are wind-based spells. According to Richard's research, the flow of air is used to play some role.

For example, condensing air and quickly forming an impenetrable wall of air to resist attacks is a wind barrier.

For example, condensing air and quickly hitting the enemy, similar to blowing at the enemy with a strong wind of level 10 or more, causing the enemy to retreat uncontrollably, is the wind repulsion.

For example, condensing air, blessing the lower limbs, increasing movement speed and bounce height, and reducing weight to become more agile, is the lightness of the wind.

For example, condensing air, blessing the upper limbs, amplifying the power of the explosion, and giving the opponent an unexpected blow is the brute force of the wind.

Richard learned these spells because of their effects, but most importantly because of the inner workings of these spells.

Flame impact, which is obviously the combustion of combustibles, must conform to the law of conservation of energy. The condensation of water droplets is liquefaction in cold and must conform to the laws of thermodynamics. The four wind spells are the category of fluid mechanics, and they must conform to the principles of fluid mechanics, such as the Plante-Grauert rule, the Carmen-Chsiensen formula, and so on.

Richard tried to explain these spells scientifically before mastering them, with the effect that the spells he cast were not as rigid as those in the Monroe Chapter.

For example, the Wind Barrier, which is recorded in the "Monroe Chapter" is only a wall of compressed air about one meter long and wide and more than thirty centimeters thick.

But Richard was able to create a super compressed air wall that was two meters long, two meters wide and two meters thick. You can even make it spherical or cylindrical.

Another example is the wind knockback, which is recorded in the "Monroe Chapter" as compressing a fixed volume of air and launching an impact on the enemy, causing a knockback effect. But after Richard cracked it with science, he could choose to use more or less air compression to achieve the desired effect.

It is even possible to stack several "Wind Knockback" together to become "Powerful Wind Knockback" or even "Extreme Wind Knockback".

Admittedly, the spells were still zero-ring spells, but Richard could make them even more useful.

Richard believed that more could be done if research continued.

......

In a flash, more than a month later.

When the first yellow leaves fell in the birch forest outside the Blue Lion, the black coffin of King Donus was being carried out of the city. It was rainy, just like the day he died.

Three days ago.

The sky was overcast, and silky autumn rain fell, hitting people with cold bones, like pins and needles. This marks the end of the hot summer and the arrival of autumn.

From early in the morning, it seems that because of the weather, the atmosphere of the whole palace is a little dull, and something is brewing in the dullness. The falling autumn rain and the sudden drop in temperature made people hide in the house, and the huge palace became extremely cold and quiet.

Richard experimented in silence.

A beaker is placed in a jar of water and heated in a water bath, and the boiling water in the jar makes a "gurgling" sound, and a large stream of white steam comes out. Richard watched from the sidelines, and then heard a faint sound coming in waves.

And the first wave, from the king's palace, with a sudden cry and panic, quickly spread throughout the palace, and then to the Blue Lion City.

"Knock knock!" Richard frowned and shouted "Enter" when there was a sharp knock on the door of the independent laboratory, and Edward stumbled in, followed by the sad old butler Delon.

"Wang ...... Your Royal Highness, Prince, Bad ...... Bad news......" Edward said breathlessly.

Delong, the old butler behind him, spoke: "Your Majesty, he ......"

Before he could finish speaking, Richard had already raised his hand, and then said expressionlessly: "I know." ”

"That ......"

"Let's go. ”

"Yes. The old butler Delon turned around and led the way, and Richard glanced at the liquid that was still heating up, and finally followed him out of the laboratory and out of the palace.

In the icy autumn rain, walk through the square and into the bedrooms of the King's Palace.

Richard saw that it had become empty, the wine cabinet in the corner was empty, and some of the furnishings had been removed. A bed was placed in the middle, and the body of King Donus lay on it, his skin purple and purple black, and he had been dead for a short time.

At this time, there was another person in front of the bed, it was the eldest prince William, who had come earlier with the news, his head next to the bed, his shoulders shaking, and no sound came out, not knowing whether to cry or laugh.

Hearing the voice, William looked up, with tears on his face, looked at Richard and said in a hoarse voice: "Brother, father, he ...... Went to ......"

"Hmm. Richard replied, no joy or sorrow.

William was obviously stunned, as if surprised by Richard's calmness, and wanted to say something, but he didn't say it, turned his head back and leaned on the bed, and kept saying, "Father...... Father ......"

Richard stood by and watched.

Moments later, the undertaker arrives and begins to groom King Donnas, which includes trimming his hair, washing his body, and putting on his clothes and armor. The rest of the attendants also began to decorate the mourning hall: cover or remove the mirrors with a black cloth, extinguish the fire in the fireplace, open all the doors and windows, open all the locks, untie all the knots, and light the candles......

In this case, William and Richard had to go out of the room.

At the entrance of the palace, the two of them stood. A gust of cold wind blew, William tightened his clothes, turned his head to Richard, and said in a hoarse voice: "Brother, my father is dead, we ......"

Richard didn't respond, just looked at the rain that kept falling from the sky and said, "It's cool, wear more clothes." ”

"Huh?" William was surprised, and after a moment Richard seemed to be reminding him kindly, and nodded in response, "Hey." ”

"It's going to rain,......" Richard added, as if there was still a second half of the sentence, but he didn't say it. Shaking his head, he walked directly into the dense rain curtain.

"When I'm buried, I'll go. The voice came from the rain.

William watched, his lips opening and closing a few times, but eventually closing again, saying nothing.
