It's no wonder that Roland is so excited, playing games, who doesn't want to easily learn new skills, and then simply play. But the spells in this game are so difficult to learn that they are completely beyond his expectations.

This is still a first-level magic, and the second-level magic failed and directly shot his head, and Roland thought of the dense node space map when he used the language spell a few hours ago, and his scalp tensed.

What about Level 3 magic, Level 4 magic, or even Level 5 magic, how many magic nodes do they have that the caster needs to understand and recognize?

Roland returned to bed and sat down a little discouraged, when the sun was already in the west, and the shadows of the trees on the mountain were covered near the thatched house, and the mountain wind blew and the shade of the trees swayed, and the spots of light mixed in it seemed to surge like waves.

Looking at the beautiful scenery outside through the grass window, and listening to the sound of the wind, insects and birds in his ears, it was too natural to be in an excellent mood, Roland felt that his mood was gradually getting better, he stood up, went outside, picked up the wooden stick just now, and returned to the four sections.

Since the magic node can't move, help it get a three-dimensional spatial coordinate to make it easy to remember. Beginner mages use low-level spells and need to recite spells, so imagine that the spell itself does not enhance the effect of magic, what if its essence is only the flow of memory magic nodes?

So wouldn't it be better to replace it with coordinates and pronounce it?

Roland drew the coordinates of the magic node while his mind was open...... The coordinates are directly applied to the most classic XYZ axis, and then distinguished by numbers. Of course, in order to prepare for the positioning of each node, Roland made a fairly precise equidistant division of the four sections.

By the time he numbered all the nodes, it was already dark. He went back to the thatched hut and rested for a while, sniffed the leftovers from noon, and found that there was no smell, so he continued to eat, and after thinking about it all afternoon, his stomach was now very hungry.

While he was eating dinner, he did not notice that Falken had walked up to the four cross-sections he had drawn. The old man looked at it carefully for a while, and his old face was full of admiration: "Spell model, such a detailed description of the nodes, even if it is the lowest level of spells, these four pictures alone can be worth ten gold coins, what a genius." ”

With his hands behind his back, Falken slowly walked back to his church, he was a priest, although he knew that this was a valuable spell model, he had no interest, he just came to see Roland's learning progress.

After a hurried dinner, Roland returned to the section again, he used the system's own photo function, the four sections and nodes were recorded, after all, there is always a time limit for human memory, but the picture is different, export the picture from the virtual cabin to the mobile hard disk, as long as it is stored well, do not delete it randomly, there is no problem for decades, or even a lifetime.

"It would be nice if the system had its own mathematical modeling software." Roland muttered, and at the same time opened the memo that came with the system and recorded the data: "Let's test this node line first." ”

X23Y1Z56...... Z55, failed.

Roland's head was clouded, and after relieving himself, he recorded the reason for the failure of the spell in his mind in the memo: such and such a node cannot be connected.

X23…… Z47, failed, reason: too many connected nodes, broken mana wire.

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, success!

Looking at a small orange fireball the size of an egg slowly floating forward, and then disappearing into the air with a thud, Roland clenched his fists heavily, and then shouted from his chest: Ha!

However, he quickly restrained his excitement, and then wrote down the successful node line in the memo, and wrote a note: Although small fireballs can be cast, the power and speed are extremely low, and they cannot form combat effectiveness.

Next, Roland tested more node lines, the number of failures became less and less, and the number of successes became more and more, but the power and speed of the small fireballs were not satisfactory, and occasionally there were good powers, looking at the small blue fireballs, the surface temperature of the light should be above two thousand degrees, but the speed was too slow, even if children could dodge away, or the speed barely went up, that is, the structure was unstable, and it disappeared before it flew many meters.

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

The mathematical model of the small fireball technique has been preliminarily established, and the next step is to carry out node reversal and verification, and Roland believes that after a few more experiments, he will definitely be able to find the best node line.

Many times, people can't be too blindly optimistic, and once they are optimistic, they will get something.

It was night, the moon was bright and the stars were sparse, and Roland was testing his magic behind the church, because the magic that was successful in front of him was generally not very powerful, and the flight distance was not far, so he relaxed his vigilance, thinking that no matter how powerful the small fireball technique was, it was not much stronger, but the moment he completed the connection of the new node, he felt that things were beyond his control.

Roland felt that the magic power on his body was being extracted in large quantities, condensing, spinning, and forming in front of him at an extremely fast speed. The small fireball that was tested before was only the size of a fist at the most, but the fireball in front of me was not only blue, but also the size of a basin, or a little bigger.

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 large fireball, and as soon as it took shape, it immediately broke away from the caster's control, and shot straight in the direction of the church, with a fast speed.

Roland immediately knew that something was wrong, and just wanted to shout, but he saw the large fireball suddenly stop in mid-air, first three times the size of the strange sky, then collapse into a small dot, and finally emit an astonishing light and a huge explosion.

The sound of the explosion was so loud that it directly shook Roland's ears to the ground, and the blazing light only lasted for less than a second, and then countless flames erupted with the terrifying explosion gas wave 360 degrees without dead ends.

Roland, who was at least six meters away from the explosion point, was directly swept away by the air wave, flew three meters in the air before landing, and rolled another five meters before stopping, he felt like he had been hit by a heavy truck, and his whole body was in pain, especially his face...... It's hot, even if it's 10 percent painful, it's very uncomfortable, like being splashed with hot oil.

The small tree, which was fifteen meters away from the explosion site, was directly slapped by the air wave and almost fell to the ground. Then a magical flame fell on the branch, instantly igniting the small tree into a large torch.

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

The terrible explosion spread from halfway up the mountain to the town of Red Earth at the foot of the mountain, and everyone was awakened by the sound of a thunderbolt, the sound of scolding, the frightened cries of babies, and the barking of dogs.
