There was nothing else in the white space, only a translucent sphere, which seemed to occupy the entire space.

The sphere slowly rotated, and through the sphere, Ye Xianglun seemed to see that inside the sphere, countless balls of various colors were suspended in the period.

I don't know how long I waited in the white space, it seemed to be a quarter of an hour, and it seemed to be half an hour, in short, at that time, Ye Xianglun was so bored that he began to count the number of small round balls in the sphere.

"The fourth level begins, please advance to the pianist and step into the sphere of their respective space!"

Finally hearing the sound of the void in the space, Ye Xianglun was already a little impatient to follow the instructions of the voice of the void and step towards the sphere in the space.

When the first foot stepped into the sphere, Ye Xianglun felt as if he was stepping into a thick liquid, the first foot was forced, and then, Ye Xianglun seemed to have been baptized by liquid all over his body, and after opening his eyes again, he found that inside the sphere, there was another huge space.

"You are now stepping into an atomic world, where there are countless kinds of atomic energy, atomic energy is also the most basic unit of matter, and next, the system will assign you a built-in space, this space, only you can see. ”

"In the built-in space, there will be several materials, namely soil (including soil, clay, sand, etc.), silk thread (including rope, silk thread, rubber band, etc.), wood (including elm, peach and other wood), ceramics (including pottery, porcelain, rubble, masonry and other fired utensils), stone (including bluestone, granite, marble and other stones), metal (including copper, iron, gold, silver and other metal materials). ”

"Each time a two-star qin master is promoted to a level, one of the creation abilities can be unlocked in turn, although these creation abilities seem to be chicken ribs when they are two-star qin masters, but they are the cornerstone of the promotion to three-star qin masters, and it is also the basic unit for making qin arrays, and the reason why two-star qin masters are called the backbone of the sect also comes from this!"

"The task of this level is to find the atoms needed for these substances from this atomic world and fill them in the corresponding molecular formulas, and after all the molecular formulas are filled, this round of the level will be completed. ”

"Note: Before each molecular formula is completed, the rest of the violinists can see the atomic energy you occupy, and only after the single molecular formula is filled in, the other party will not be able to see the atomic energy you occupy!"

After the voice of the void was finished, Ye Xianglun began to examine these substances in the self-contained space, only to see that this small self-contained space appeared in the upper right corner of his line of sight like a screen, and the six substances listed in the space corresponded to some grooves, and the grooves were marked with the names of the atomic energy required by the molecules.

Combined with the narration of the Voice of the Void, Ye Xianglun probably knew that his current task was to collect the atomic energy he needed in this atomic world, and stuff the required source energy into the corresponding groove of his own space.

For example, the atomic energy required for soil is C (carbon) H (hydrogen) and O (oxygen), and as long as these three atomic energies are found in this atomic world and filled in the grooves, the corresponding molecular formula can be completed.

This built-in space is transparent, and it does not affect Ye Xianglun's line of sight, just like the equipment bar or taskbar interface in a computer game, which allows him to clearly see the atomic energy he still needs.

After Ye Xianglun realized that everything was OK, he walked in this vast light blue space.

When he stepped into this space, Ye Xianglun found that this space was completely different from the space he had experienced before, in it, although he was wrapped in a light blue liquid, his breathing action was completely unhindered, and even his whole body had a faint buoyancy, as long as his feet were a little hard, he could climb up to infinity.

The terrain in front of you is more like a reef, and with some entwined greenery, it looks like an underwater world.

"Wait!" Ye Xianglun suddenly realized some problems when he took the breaststroke posture to set foot in this pale blue world, "Why didn't you see other promoted piano masters at the end of the three rounds of levels, and heard the system announce the number of promotions?"

Ye Xianglun would not be stupid enough to think that he was the only one who was promoted in this round of levels, but what was the reason why he did not announce the other promoted pianists?

Ye Xianglun couldn't come up with it for a while, so he had to leave him behind.

After stepping into this vast "underwater world", Ye Xianglun saw that there were countless other atomic energies in this world, and these atomic energies were like swimming fish on the bottom of the sea, shuttling back and forth in space.

"Boom-"

A sudden explosion resounded from behind Ye Xianglun, and when he turned his head to look, he found that it was the explosion sound caused by the atomic energy shuttling and hitting the reef, which also means that if you accidentally bump into these shuttling atomic energy, it is likely to cause an unwarranted disaster.

After getting this conclusion, Ye Xianglun began to pay attention to the shuttle atomic energy, he didn't want to be eliminated in this round because of this risky move.

Running forward along the undercurrent of the "bottom of the sea", Ye Xianglun looked around at the atomic energy coming and going, but he didn't know which one was the atomic energy he was looking for.

Looking forward along the built-in space, Ye Xianglun found that in the far distance of the light blue space on the screen, there was also a flickering "dood-" prompt sound.

"Could it be that I have the atomic energy I need?" Ye Xianglun was puzzled, and marched forward, finding that the place where the prompt sound was shining, there was still a considerable amount of time away from him, and with a thought, he untied the guqin and galloped away in the direction of the prompt sound.

The note disc in the light blue space is more like a yacht traveling through the space, Ye Xianglun relied on his own reaction, dexterously dodging the oncoming atomic energy, after a period of speed, he really saw a suddenly open place in front of him, a group of atomic energy of various colors swimming in it.

"Doodoo-"

"Doodoo-"

"Doodoo-"

Standing in front of this wide space, the screen with its own space flashed with many prompts, which showed that there were many atomic energies in this space that they were looking for.

"Is this level that simple?"

Seeing the full pool of atomic energy, Ye Xianglun was as excited as if he had discovered a treasure, the strings were plucked, and when he was about to drive into this treasure land, he was blocked by something like transparent glass.

"Wait for the other luthiers to arrive before you can enter the atomic pool!" the sound of the void rang out at the same time.

"Sure enough, there are other luthiers!" Ye Xianglun sighed and waited calmly outside the atomic pool.

"The piano master is finished, you can enter the pool!" After waiting for about a quarter of an hour, the sound of the void made Ye Xianglun, who was waiting, cheer up again.

The strings were plucked, Ye Xianglun tried to enter from the previous position, and found that there was no barrier where it was just blocked.

After easily entering the pool, Ye Xianglun looked left and right and found that there was no pianist in the huge pond.

"Why can't you see other luthiers?"

Ye Xianglun just asked, but he saw a shining light in the pond, and at the same time, the voice of the void reported: "A pianist soil atom has been recorded!"

"Two luthiers have finished recording the soil atoms!" Immediately after, the sound of the void sounded again.

Ye Xianglun noticed that in the pond, these swimming atomic energies seem to be converging, and when the three atomic energies of C, H, and O converge together, the screen will automatically light up, and the system will broadcast it at the same time.

"Could it be that we can't see each other?"

After getting this guess, Ye Xianglun was shocked, and at the same time saw that the number of available atomic energy in the pond was getting smaller and smaller, and under the crisis, he had to start capturing these gradually decreasing atomic energy.
