Valen's eyes were like torch, murmured:

"If you want to know the mass of the earth's center, you need to know the radius of the earth's center under your feet! Since you think the earth's center is a sphere, you only need to know the angle between the sun's direct radius, you can know the circumference of the earth and then calculate the radius.

It's too simple, the knowledge of elementary mathematics is enough."

Valen threw the magic scroll aside with half of it, opened the door of the enclosed room, and ran to the top floor. Sulu was a little confused. He hesitated, put away the suspended scroll, and followed Valen up the stairs.

When he climbed up to the top of the stairs, he found that Valen had turned the place where they store their observation data in a mess. He murmured something like "direct shot, angle, distance" and so on, which made Sulu feel a little confused.

"Finished, found!"

Valen was crazy, and he found the direct sun data he collected when he was the president of the local magic council in the northern city-state of Milne.

"The angle included is*, and the data I measured in the tower is also needed..."

He whispered for a while and finally found it. Once the two data were combined, he easily calculated the degree from the center of the earth to the two points, and then calculated the circumference and radius.

As soon as Valen turned around, he found that Sulu had handed him the magic scroll. He smiled slightly at Sulu, and wrote on the scroll with a quill trembling fingers:

"The measurement method of the center radius is as follows... From this we can see that the center radius is ***, and the gravity constant is ***. According to the Ace formula, we can see that the center mass is ***."

The quill finally finished writing these words. Valen sat there as if he had used all his strength. Thunder roared outside the window, the rising sun was rising, and the breath of the great source was happy. A large amount of breath poured into Valen's body, and a very small amount of breath poured into Sulu.

Valen's fatigue suddenly subsided. The twisting scale of his experiment suddenly broke through the closed room and flew to Valen. Under the washing of the breath of the big source, he transformed rapidly with Valen.

Valen's momentum gradually improved, and Ace outside the villa also felt it. He looked at Bayern and confirmed that it was a breakthrough.

There is no doubt that with the feedback from Dayuan, Valen successfully became a second-level wizard. His soul secret space expanded rapidly and turned into an empty shell and mental world.

The twisting scale was completely transformed into a unique golden spell model because of the cleaning of the breath of the big source. Instantly, the talisman culture turned into a unique golden spell model and instantly entered the empty world of Valen's mind.

Valen's strength also instantly reached the peak of level 2 and became another golden wizard.

Ace also felt the shock. The clone in the wizard's subconscious mind suddenly opened his eyes, and the white light burst out. Ace instantly resonated with the clone and obtained information feedback from the clone.

The entire subconscious sea is no longer the prototype of its former form, but a surging ocean of ocean. After Ace was promoted to a third-level wizard and several wizards were promoted to a second-level 2, the entire subconscious sea has been completely formed.

It is the common subconscious of the wizards and also precipitates the memories of the wizards. According to the original contract, Ace obtained the spell model obtained by Valen Dayuan feedback.

The magical twist scale spell model also appeared in Ace's heart-image world. Magic gave the twist scale a much extraordinary power. At the second level, it can measure constants and slightly change constants. At the third level, it has great potential to twist gravity and change gravitational constants!

Ace's eyes were flashing with white light, and his mind was sinking into the world of mind and harmony with the true spirit, holding up this golden spell model and carefully observing it.

"Many golden runes are similar to the third-level gravity runes I found, so it should be easier to deduce them."

The daimao above Ace's head shaking violently. When it reached the legendary level, Daimao's ability to deduce rules was only to bless Ace, and the effect was much worse.

Fortunately, this deduction was not a deduction from scratch, but was replaced by similarity, which was much faster. In less than half an hour, Ace deduced the third-level rune of this twisted scale spell model.

This is the structure given by Dayuan, which is very perfect, with almost no modification. Ace directly embedded this rune structure into the spell model "Gratitude" and perfectly integrated.

At the same time, a phantom of a twisted scale appeared in Ace's dream starry sky world.

Ace Zhenling's eyes flashed with white light and said softly: "This phantom of the treasure can be turned into reality as long as it is filled with enough resources. It can be called the treasure 'constant twist scale'."

Thirteen treasure stars surround the phantom of the treasure. The true spirit of Ace floated under it, and the glazed heart fire on its head slowly resonated with it. This is also a method of fertilization. It is made by using existing treasures and thoughts and heart fire together. However, it takes a long time to conceive the treasures in this way.

The third-level legend has a lifespan of thousands of years, and it is difficult to give birth to treasures like this several times. Most legendary heroes specialize in one field, and even have only one treasure in their lifetime.

When Ace opened his eyes, everyone was looking at him worriedly, and Valen and Sulu had also come out to wait for a while.

"Mr. Ace, are you okay?"

Dana asked with some concern.

Ace shook his head: "I just suddenly thought of a mathematical problem and forgot about God for a moment. Congratulations to Valen, congratulations on discovering the new mysteries in the field of mechanics, and even more congratulations on becoming a golden wizard!"

Ace's "Eye of True Knowledge" did not dissipate. In his eyes, the breath of Valen's great source was surrounded by light gold and pure red. It was exactly the limit of the second-level life, the Golden Wizard.

Valen was also very excited. He had a premonition that this discovery might have cognitive feedback from Dayuan, but when his strength really increased greatly and he obtained the God-given magic model, he was also so excited that he couldn't suppress himself.

"Mr. Ace, it depends entirely on the gravitational formula you discovered. Only Sulu and I can successfully measure the gravity constant and the mass of the earth. We 'weight' the center of the earth!"

This words were like a heart-boosting shot, which made everyone feel excited. The Torte clone who had just arrived also trembled. Even the true god may not necessarily know the weight of the earth's center, nor do they know the gravitational constant. The gods are only omniscient in their realm. Perhaps the Earth God knows it, but He will never tell anyone.

Tot couldn't help but applaud, attracting everyone's attention. He did not hide his whereabouts, and his body was covered with the glory of divine power.

Ace led the wizards to salute him quickly, and Tot waved his hand and said, "You are so surprised that the study of magic can achieve such a great discovery and become the shelter of wizards. I am better than you in terms of existence and absolute power, but on the road of magic, you are my teachers."

The wizards hurriedly returned the greeting and said they didn't dare. They all knew that Tot was very interested in magic and even turned into a magic school to study.

After encouraging Valen for a few words, Tot left in a drift.
