It was around two or three o'clock in the afternoon, which was the hottest moment of the day.

Even the naughtiest children in the Guadi tribe learned to hide under the shade of trees at this moment, but the women and the elderly were still busy picking and collecting various wild vegetables and insects in the valley.

As for Wu Yuan, he had already taken more than a dozen of the strongest warriors of the Guadi tribe to go out to hunt in the valley when the weather was the hottest, because only during this period could he avoid the evil, terrifying and cold sand snakes.

At this time, Zhang Yang was hungry and collecting firewood all over the world without a source of magic power, so he had to need enough firewood.

Of course, he did not forget the sacred thing of rubbing the wooden spear, but unfortunately, he has not thought of any way to rub the wooden spear so far.

When the sun began to hang on the hill to the west, Wu Yuan finally returned, bringing two unknown ferocious beasts. It seemed that there was no need to worry about dinner.

Zhang Yang also collected two piles of firewood at this time, but he didn't feel tired, just one word, hunger!

Wu Yuan's relationship was divided into another piece of meat bone, and he threw it in the fire for a little bit of cooking. He quickly ran aside and swallowed it with all his life, otherwise he would wait for a few seconds and this hard-earned piece of food would probably change hands.

"Mr. Village Chief, do you want to use fire attack to deal with the sand snake?"

After arranging everything in the Guadi tribe and driving all the people into the cave, Wu Yuan came over and asked.

"What, what's wrong?"

Zhang Yang sat on the ground and replied casually, he was thinking about the internal structure of the fireball spell.

"Mr. Village Chief, if you are dealing with ordinary sand snakes, these firewood will certainly scare them away when ignited, but what we have to deal with is most likely the sand snake king."

"No need to consider these for now. Don't block the cave tonight, I'm going to spend the night outside."

When Wu Yuan was scared to the point of jumping to the point of hearing Zhang Yang's words, he hurriedly said:

"My village chief, that is absolutely impossible. You don't know how terrible the nights here are. I don't know how many night beasts are in the air. Even lighting a bonfire will be useless."

Zhang Yang looked up, looked at Wu Yuan carefully for a while, and suddenly said:

"Did the memories left by the leader of the Guadi tribe affect you? Don't be too busy denying that soul memory is magical, but we don't have to worry about these things. Wu Yuan, I just ask you, you taught me to be awe, so now, have you forgotten our true intention of coming to this world?"

"Do you think the arrival of the Sand Snake King is the beginning of the trial in five days? Wrong, the trial has begun long ago. Do you, Wu Yuan, want to be the leader of a primitive man in this primitive era, or follow me to be a hero, and create a bigger and more magnificent era?"

"A person needs to constantly break through his limits and potential, constantly oppress himself to grow, so that he can realize his own value and assume greater responsibilities. I have a deep understanding of this."

"Single people need this, a tribe, a race of life, and even a civilization, even more so. Do you know why Neanderthals were called cavemen? Because they did not learn to walk out of the cave until their race completely perished. However, our human ancestor Homo sapiens walked out of the cave early and bravely, so we won in the end."

"Of course you may not understand these things, it doesn't matter. Now I'll ask you again, are you going back to your cave, block it with stones, or come out boldly? You want to be a hero. You should have the courage and courage that ordinary people do not have, rather than being as gentle as an old mother, and losing sight of one thing!"

"Tell me, where is my spearman king? Where is the hero of the village!"

Zhang Yang almost shouted this sentence, and then took advantage of Wu Yuan's moment of confusion, the soul power field directly enveloped and compressed instantly!

At this moment, Wu Yuan's hill-like body trembled violently as if it was electric shocked. It took him more than ten seconds to return to normal, and his eyes became sharp and deep again. This is the familiar Wu Yuan.

"My village chief, I'm very ashamed."

Wu Yuan bowed and bowed.

"Hehe, there's nothing to be ashamed of. This is also part of the hero trial. Now at least you have passed this trial, and it's thanks to your will to be strong enough, otherwise I wouldn't be able to awaken you through a second-hand speech and soul impact."

Zhang Yang smiled and didn't care. He was telling the truth. He discovered something wrong with Wu Yuan this morning, but he didn't take it seriously at that time. It was not until the whole day that he realized the seriousness of the problem, that is, Wu Yuan's every move, every word and action began to gradually move closer to the leader of the Guadi tribe.

This is not possible. They are here to pass the hero trial, not to play role-playing.

If Wu Yuan is not awakened immediately, then in the end, Wu Yuan will really become the real leader of the Guadi tribe, and the heroic trial will naturally fail.

"Mr. Village Chief, please wait."

Wu Yuan turned around and called out five adult men from the Guadai tribe from the cave. While they were not paying attention, he pushed the big stone over by himself, completely blocking the cave.

"Quada, Quada!"

"Oh yell, yell!"

The five men from Guda tribe went crazy, shouting and jumping, and trying to push the big stone away, but Wu Yuan kicked them away.

Finally, the five people squatted there in despair and cried, shivering as if they were little beasts, but they no longer tried to escape back to the cave.

"It's not bad!"

Zhang Yang slapped Wu Yuan’s high five, “But are you sure that only the seven of us can spend this night safely?”

"The spearmen have always advanced but not retreated, and I am invincible, and the others are not within the scope of consideration."

Wu Yuan's answer was so powerful that he could make him feel as if he was so strong that he felt completely relieved and began to continue studying his fireball structure while the sun had not set.

As for Wu Yuan, he forced the five Guadi tribe men to bring more stones and trees by punching and kicking.

I have to say that the Neanderthals are so cruel that they can knock down a big tree by relying on their fists and feet.

It's the most suitable Berserker candidate.

"From the analysis of my soul force field, there are a total of fifteen structures in the orc's fireball spell, and these fifteen structures are divided into four ring structures."

Zhang Yang held a small branch and wrote and painted on the ground. Because there was no quick supplement of the Wood Demon Tower, he could not use the soul force field to conduct simulation experiments, so he had to use the drawing method.

What he unexpectedly expected was that through the original method of drawing pictures, another mapping structure of the fireball spell could be clearly displayed.

"The ring, or closed-circuit circle, is basically the core of the fireball spell. Relying on this core, four different closed-circuit circles can be analyzed, just like nesting dolls."

"The first closed-circuit circle is the innermost circle, but not the core circle. It has four structures in total. The role played by the fireball spell is similar to the spark plug of a gasoline engine, that is, input mana, build a closed-circuit circle of mana, and finally form preliminary compression."

"This process requires very high skills, and it requires the ability to sense mana and have sufficient mana reserves. It requires almost 0.1 unit mana. For the time being, I know the principle but can't do it because the skills are not enough, and I lack the body to reserve mana."

"But I can now abandon this link directly. After all, I use ordinary flames to replace mana, so I can directly enter the second closed-circle."

"This second closed-circuit circle collapses through the compression and collapse of the first closed-circuit circle, and then forms a magical curved force field. In this curved force field, matter will continue to move closer to the center without escaping. At this time, the external situation is that a fireball appeared in the hands of the orc mage, but the fireball did not disperse and explode, but was gradually increasing."

"Well, that's it. The power of a specific fireball depends on how attractive the curved force field formed by the second closed-circuit circle structure is. The greater the gravity of the curved force field, the more mana it can be compressed through the first closed-circuit circle injection, which is similar to the difference between an eight-cylinder engine and a sixteen-cylinder engine. Although I never know the principle of the engine, what's the relationship? The simplest way."

"Then there is the third closed-circuit circle. The function of this closed-circuit circle is to assist and maintain stability, which is optional. In other words, if you are a rookie mage, you must use this closed-circuit circle. If you are a great magician, you can directly use the first two closed-circuit circles to get it done. It is estimated that this is the principle of instant magic. The fewer closed-circuit circles, the less magic structure. Well, is this serious nonsense really good?"

Zhang Yang couldn't help but chuckled. After all, he had seen an orc mage so far. Such a wanton reasoning master is too interesting and fun.

"The last is the fourth closed-circuit circle. There are only two mana structures here. It is very simple. It is a structure that aims and drives the fireball to fly, similar to a power output device. Where does the power source come from? Of course, it is the heat generated when the mana collapses and burns. Injects these two structures and then advances through air compression. Hey, I suddenly feel that both mages should be scientists. Look at these two structures, it is very consistent with aerodynamics. Who would have thought that a fireball spell actually contains the principle of a jet fighter?"

"So these two structures are wonderful. If I want to develop a powerful weapon like the Eight Niu Crossbow and the Siege Crossbow in the future, the two magic structures must be portrayed on the crossbow arrow, etc. Isn't this the principle of the battle pattern? As expected, as long as anything goes to a deeper level, it is all about the same."

"To sum up, I only need to intercept the second closed-circuit circle and the fourth closed-circuit circle, a total of eight mana structures. Then I can successfully release the fireball through the micro-operation of the soul power field. I can name it Zhang's Fire Burning!"
