It’s not that Roland is so excited. Playing games, no one wants to learn new skills easily and then play them simply. But the spells of this game are so difficult to learn, which is completely beyond his expectations.

This is still first-level magic. The failure of the second-level magic directly hit the head. When Roland thought of the dense node space maps when he used language spells a few hours ago, the dense node space maps were tightened.

Level 3 magic, level 4 magic, or even level 5 magic, how many magic nodes do they have to understand and recognize?

Roland returned to the bed and sat down a little discouraged. At this time, the sun was already west. The shade of trees on the mountain was covered in the vicinity of the thatched house. The mountain wind blew, the shade of trees swayed, and the spots mixed in it seemed to surge like waves.

Through the grass window, looking at the beautiful scenery outside, listening to the sound of wind and insects and birds in his ears, it was so natural that it was a great mood calmer. Roland felt that his mood gradually improved a lot. He stood up, went out, picked up the wooden stick just now, and returned to the four sectional pictures.

Since the magic node does not move, help it to make three-dimensional spatial coordinates to facilitate memory. Beginners need to chant spells when using low-level spells. Let’s imagine here that the spell itself does not have the effect of strengthening magic. What if its essence is just the flow of the magic node?

So, wouldn’t it be better to replace it with coordinates?

While Roland drew coordinates for magic nodes, he also opened his mind... The coordinates directly applied the most classic xyz axis and were divided by numbers. Of course, in order to prepare to locate each node, Roland made a very accurate isometric division of the four sectional diagrams.

When he numbered all the nodes, it was already dark. He returned to the thatched room to rest for a while, then sniffed the leftovers at noon, and found that it was not smelly, so he continued to eat it. After thinking for a while, he was very hungry now.

Just as he was having dinner, he didn't notice that Falken walked to the four sectional pictures he drew. The old man looked at it carefully for a while and his face was full of admiration: "The spell model is such a detailed node narrative. Even if the lowest-level spell is analyzed, these four pictures alone can still be worth ten gold coins. It's such a genius."

Falken slowly walked back to his church with his hands on his back. He was a pastor. Although he knew that this was a valuable spell model, he had no interest. He came here just to see Roland's learning progress.

After having dinner in a hurry, Roland returned to the sectional view again. He used the system's own photo function to record the four sectional views and nodes. After all, there is always a time limit for people's memory, but the pictures are different. Export the picture from the virtual cabin to the mobile hard disk. As long as it is well preserved and not deleted randomly, there will be no problem for decades or even a lifetime.

"It would be great if the system comes with mathematical modeling software." Roland murmured, and opened the memo that comes with the system and recorded the data: "Test this node line first."

x23y1z56...z55, failed.

Roland's head was blinded, and after he recovered, he recorded in the memo with his mind that the reason for the failure of this spell casting was: a certain node and a certain node could not be connected.

x23...z47, Failed, Reason: Too many connected nodes, the magic line breaks.

x23...z11, failed, reason: the node connection speed is too fast.

x23...z12, Failed, Reason: A certain node cannot be connected to a certain node.

x23…z09, successful!

Looking at the small orange-yellow fireball as big as an egg, slowly floated forward, and then disappeared into the air with a popping sound. Roland clenched his fists heavily, and then shouted out from his chest: Ha!

However, he soon calmed down his excitement, and then recorded the node line of success in the memo, and wrote a note: Although a small fireball can be cast, its power and speed are extremely low, and it cannot form combat power.

Next, Roland tested more node lines, and the number of failures became fewer and fewer, and the number of successes was more and more. However, the power and speed of the small fireball were not satisfactory. Occasionally, there were good power. Looking at the small blue fireball, the surface temperature of the light should be above 2,000 degrees. Unfortunately, the speed was too slow. Even children could flash. Otherwise, the speed would be barely up, and the structure would be unstable and disappeared without flying many meters.

Now in his memo, there are more and more records of node lines, densely packed, and several very important nodes are gradually marked.

The mathematical model of the small fireball technique has been initially established, and the next thing is to reverse the node and verify it. Roland believes that if he conducts a few more experiments, he will definitely be able to find the best node line.

Many times, people cannot be too blindly optimistic, and things will happen if they are optimistic.

It was night at this time, with the moon and the stars sparse. Roland was testing magic behind the church. Because the magic that was successful in front was generally not very powerful and the flight distance was not far away, he relaxed his vigilance and believed that no matter how powerful the small fireball technique was, it was not much stronger. But the moment he completed the new node connection, he felt that things were beyond his control.

Roland felt that the magic power on his body was drawn in large quantities, condensing, rotating and forming in front of him at an extremely fast speed. The small fireball I tested before was only the size of a fist, and the fireball in front of him was not only blue, but also as big as a washbasin, or even a little larger.

This is no longer a small fireball, it should be called a big fireball.

The magic power in Roland's body was almost all supplied to this big fireball. As soon as it formed, it immediately broke away from the caster's control and shot straight towards the church, at a very fast speed.

Roland suddenly knew that something was wrong. Just as he was about to shout, he saw the big fireball suddenly stopping in the air. First, it increased strangely three times larger, and then shrank and collapsed into a small dot, and finally emitted an astonishing light and a huge explosion.

The explosion was so loud that Roland was roaring in his ears. The blazing light lasted for less than a second, and then countless flames gushed out with the terrifying explosion air waves of 360 degrees without dead corners.

Roland, at least six meters away from the explosion point, was directly blown away by the air waves. He flew three meters in the air before landing, and rolled five meters before stopping. He felt like he was hit by a heavy truck, and his whole body was in pain, especially his face... It was so hot that even the pain was ten percent very uncomfortable, as if he was splashed with hot oil.

The small tree fifteen meters away from the explosion point was shot directly by the air waves and almost fell to the ground. Then a magic flame fell on the branches, instantly lit the small tree into a bunch of big torches.

The back wall of the church was directly collapsed half of it.
