While Rollin was concentrating on upgrading the functions of the virtual souls, Alan placed the six virtual souls in the special magic crystals.

This magic crystal can provide the magic power for the virtual soul to operate, and there is also a mind transformation rune, which can convert the consciousness fluctuations of the virtual soul into actual sounds, and can also convert the sound into consciousness fluctuations, which is a very effective input and output device.

When it was finished, Alan gave the balls a very lofty name, the Orb of Truth.

On the second day of Reason, she showed her halfling apprentices the magical crystal balls.

"Who can guess what this thing does?" Alan asked with a smile, not expecting an answer, just using the question to gather the apprentices' attention.

Sure enough, as soon as this question was asked, the attention of the halflings present was on the crystal ball.

These crystal balls look delicate, they glow, and there is a soft light cluster inside the pure water-like crystal, and if you look closely, you can see that the structure of this light ball is extremely complex.

"A new type of bomb?" Bomb expert Albert was the first to answer.

Alan curled the corners of his lips in amusement, this Albert is so funny. She shook her head, repudiating his speculation.

"It's a ball of knowledge, and it stores knowledge in it." Aroin stood up and said.

This answer is very reliable, it is very close to the answer, Alan can't help but look at this little guy more, this Eloin is really intuitive. But she shook her head and encouraged, "Guess again." ”

Aroin is actually thinking wildly, and you tell him to think about another one. He couldn't think of it. Such a crystal ball. He'd never seen it before.

Then a few more apprentices opened their mouths to guess, but the answers were not very reliable, what fish tanks, candlesticks came out, and Alan waved his hand to stop the halflings' wild imagination.

"I call it the Ball of Truth. There is an alchemy soul stored in it, which can answer some of your questions and help you complete some tedious calculations. ”

As he spoke, Alan held his hand lightly, and a ball of truth floated. Fly up to Arrowin's eyes: "Ask it with the computational puzzle you think is very difficult." ”

Arrown thought about it for a moment and came up with a calculation that he thought was very difficult: "What number multiplies itself four times in a row equals 5, well, I just need a value accurate to four decimal places." ”

Almost as soon as he finished speaking, the Ball of Truth reported the answer: "1.3797." ”

Aroin immediately picked up the charcoal pen and counted it on the hide, and after a few minutes, his eyes suddenly widened: "That's right! ”

The other halflings were also calculating and verifying, and they all got the same answer as Eloin, and they all took a breath, such calculations didn't do much in practice. It's used for fun by them, usually to see who can calculate faster. The winner will receive some reward, such as a copper or something.

In the past, Aroin basically won all the victories, but today, he was dumbfounded by the orb of truth given by the divine envoy, which is not like words!

Not reconciled, he immediately reported an even more difficult one: "What is the exact ratio of circumference and diameter of a circle?" ”

He used the circumcision technique of the Divine Envoy Sect for several days to calculate this ratio, and came up with a value of 3.14, but he knew that this number was only an approximation.

At the same moment when his voice fell, the answer arrived: "3.141592653"

Eloin was stunned, he had no way of verifying it, but he knew that this promise must be right: "Teacher, this is a miracle!"

Alan was also very emotional, she thought of the time when the elves were beaten by the goblins and were powerless to fight back, and couldn't help but sigh and said, "This is indeed a technique taught by the gods. These orbs of truth have incredibly powerful computing power that will help you use and discover knowledge faster and more accurately. There are six of them here for the time being, Aroin, and you are in charge of one. ”

"Yes, Mentor." Arrow's hands trembled, and he carefully held the ball of truth in his palm.

"Albert, you're the one too." A crystal ball flew over, and Albert's face flushed, and his reaction was even more intense than that of Eloin.

"Monroca." "Nolai", "Devonsy", "Gross"

Alan quickly divided the crystal ball, and the people who got the crystal ball were all halflings who had convincing achievements in their own fields, and each halfling was like a treasure, holding the crystal ball, holding it in his mouth for fear of melting, and holding it in his hand for fear of falling.

Ignoring their reactions, Alan began to explain the function of the Ball of Truth: "They can do very complex numerical calculations, but they are far from omnipotent. They are only convenient tools and will not be able to discover the truth for you, so you must continue to work hard. ”

This is just the lowest level of virtual souls, and its abilities are very limited, according to Rollin, this is just a calculation tool at all, only a little more advanced than the small wooden stick that the halflings are currently using to count.

"Yes, Mentor." The halflings replied earnestly.

Next, Alan began to give the usual lecture, she taught the flight science she had promised before, and the halflings who had just experienced flying listened to it with fascination.

By the end of the course, most of the halflings were discussing how to build a flying machine, but Aroin didn't know what was going on in his head, and he had seen the power of the fire bomb and had a very strange idea.

Albert added iron pieces to the fire bomb to increase the power of the fire bomb, which was propelled by the flames at high speed, and was very lethal, and he saw with his own eyes that the iron piece cut through the leather of the dire crocodile.

That is to say, the flames are not fierce, but the flames that erupt violently have a huge driving force, which can push the pieces of iron and the stones to fly out.

Today, the instructor gave another lecture on aerology, and she gave an example that as long as you can control the flame of the sky, you can fly in the sky.

This example runs through all of Aroin's thoughts: 'If you find a way to control the flames, you can not only fly, but also invent a way to propel it with flames.' A weapon with very high lethality. Even more powerful than trebuchets. ”

Compared to the realization of flight. Albert found himself more enthusiastic about the latter, and he even came up with specific control methods in his head.

Thrilled by his idea, he looked left and right, and soon found the bomb expert Albert, who was holding his orb of truth and the other halflings discussing how to fly with fire.

After listening for a while, Eloin realized that Albert's idea was more of an empty talk, and that their craftsmen were simply not able to make the iron tools he spoke of for precise control.

He didn't bother for a moment, but sat down. Wipe the charcoal off the hide, and then start drawing the thoughts in your head.

It was a hollow iron pipe, and it was difficult to make, and Arrown knew that, but it wasn't out of the question, and maybe it would be a good idea to roll up the pieces of iron.

He envisioned stuffing the explosive flame agent on one side of the iron pipe, and then stuffing the iron piece on the other side, no, the iron ball is better, it will better block the iron pipe, and then it will ignite the agent. The potion explodes, generating tremendous power. If the iron bead can reach a small half of the power of the explosion, it will be enough to deal with the lazy giants in the Holy Land, and maybe the iron ball can punch a hole in the opponent's body.

"Hey, what are you drawing?" A voice came, it was Albert, he was attracted to it, and Aroin was still drawing on the hide, while explaining: "I call it an exploding iron orb, you see, if your fire potion explodes like this, will it push the iron orb out?" ”

Albert was immediately intrigued, and he saw at a glance that the thing was of great possibility, much more practical than the erratic flight.

He scrutinized it, and with his knowledge of the power of the explosion, he said with certainty, "I can push it out." If the amount of medicine is controlled, and the iron pipe is very precise, it may not be damaged in the explosion, but the iron ball will fly very far, and if it hits something, the thing that is hit will be unlucky. ”

As he spoke, he greeted a halfling, "Monroca, come and see this." Aroin has come up with a new gadget and needs a new Iron Guy. I bet you won't be able to figure it out. ”

"What? Let me see. As long as it's iron, I'll be able to figure it out! Monroka was hit by the agitation and immediately rushed over.

He saw the iron pipe on the drawing, and his eyes widened suddenly: "It's difficult, it's difficult, let me think about it carefully, you also marked the precision, it's difficult to achieve such a precise thing, but it's not impossible, I want to think, I want to think"

The halfling fell into deep thought.

Aroin was not idle, he continued to let his imagination run wild, and every once in a while, he would ask the Orb of Truth some calculations, or write some strange calculations on the hides. Almost none of the halflings around him could understand what he was thinking, all they knew was that this Eloin had a very good brain.

After half an hour, Monroca clapped his hands violently: "No, I'm going to try it myself." This question is very challenging. My heart is already burning with the furnace! ”

He strode out of the hall of knowledge, and when he reached the threshold, he fell hard, but the halfling didn't care, he got up and continued to run, looking in the direction, it was the iron-making furnace shop.

After a while, Albert also clapped his hands: "I feel that this kind of thing may need a new fire potion, and I am going to improve my potion." ”

He also hurried away.

For a moment, the geniuses of the halfling's apprentices regained the same enthusiasm they had used to build trebuchets and began to focus on this new explosive iron pipe.

They could all sense the potential of this thing, and its burst of power might be more terrifying than a trebuchet, and it might be able to change the disadvantage of a halfling's weak body

In the inner sanctum of the Temple of Life, Alan was watching the scene that happened in the Hall of Knowledge through her divine thoughts, and she laughed, and she mapped the drawings drawn by Eloin into the air: "Look, familiar, right?" ”

Luo Lin smiled: "Huh~ Isn't this a magic musket?" (To be continued......)
