After Tianxuan and his group of five passed through the iron tree layer, what appeared in front of them was no longer a lifeless gray earth, but a very bright area.

"Wait!" Thrall motioned to stop, "The land we will reach after this downhill is called the Streamer. This streamer is located in the last area of the upper mantle, about 100-900 kilometers above the ground, of course, there are errors in some places, through this area we will reach the lower mantle, where the main city of Maya is. ”

"Oh! That's going to be there soon! Tianxuan felt that things were quite simple.

"I hope so. However, due to the recent underground movement, many passages were forced to close to avoid the effects of magma eruptions and earthquakes, so we made a detour through the Iron Tree Layer. For now, let's take a look at the situation of the channel before making a conclusion. But Tianxuan, do you know what this streamer layer means? Sal said.

"What do you mean?" Tianxuan

"The streamer layer means stream and light. You see, that colorful land is actually magma of various colors. The reason why this area is so bright is because of these magmas. "Sal

"Magma?" Tianxuan's eyes widened, and the scene in front of him surprised him: white magma, golden-white magma, golden-yellow magma, orange magma, orange-red magma, dark red magma, some of which were intertwined like rice cakes, and some of which formed a single-color fountain pool, like a colorful stream, dazzling, like a fairyland.

"What's the matter, fascinated by this beautiful view?" Sal asked with a smile

"Indeed, Mr. Sal. I never knew that magma came in so many colors, one thought it was only that red magma. "Tianxuan

"That's because the magma on your ground is metamorphosed, and the Streamer is where the magma originates. The original magma is dark red, the temperature is very low, and most of the magma energy is converted into heat energy in the process of rising, and then absorbs various substances on the way to change color. This is like the flame color and temperature correspondence of smelting fuel under normal conditions: for example, dark red is below 600 °C, dark red is 700 °C, orange is 1000 °C, pure orange is 1100 °C, golden orange is 1200 °C, golden yellow is 1300 °C, golden white is 1400 °C, pure white is 1500 °C, white is above 1500 °C. So blue magma is basically hard to see. "Sal

"Oh! That's true, there are all kinds of colors, but the blue magma is missing! "Tianxuan

Sall paused and said, "Tianxuan, I will slowly explain this knowledge to you in detail in the future, but it is very important for you to pay attention to the things that are said below, and you must listen clearly: you should already know the place of those fountains, and you must not touch them." However, there are some places where there are no fountains. ”

Tianxuan looked at the places without fountains and seemed to look the same, so he asked suspiciously: "Mr. Sal, how do I look the same, how can I tell the difference?" ”

"Quite simply, the ground below is reflective and you can walk, which is the crystalline solidification of the magma after cooling; Where there is no reflection, we call it magma mud, just like a swamp, you can't climb up if you step on it! Sal admonished solemnly.

"If I accidentally fall down, I have to trouble you to get me up quickly! Mr. Sal, I'm a rough man, I'm afraid I'm going to cause you trouble! Tianxuan said with a bit of a hippie self-deprecation.

"Don't worry, I won't need to save you if you fall." Hercules

"Nari? You're kidding, Hercules! "Tianxuan

"Nope! Hercules was right. Sal said, grabbing a large clod of dirt from the ground and throwing it at the non-reflective lava mud. Then the clod of dirt landed on the lava mud without any incident, and began to sink as if it had fallen into a swamp. However, something unexpected happened, sparks erupted after the magma mud was squeezed, and then Tianxuan faintly saw a hot and flowing liquid appear under the sparks. At this moment, the large clod of earth was melted by the hot magma, and even the ash could not be seen.

"Uh, uh, things are getting a little complicated now!" Tianxuan raised his throat, thinking that falling like this would really be open to flesh and bones. Then he stroked his chest with his hand and suppressed his shock.

"You know, I'm scared! Ay! Rookie be careful! See you Uncle Hercules help you open the way ahead, follow well, don't fall behind. Hercules said proudly with her head held high.

"Well, hello, you're strong. I'll leave it to you! Tianxuan looked a little embarrassed, but this matter really had to be convinced, and he couldn't be strong.

After making full preparations, the five pioneers drove down the dirt slope and into the streamer. The five of them drove cautiously on the crystal soil, but the road was not smooth, and there were many times when they went around and around, but fortunately, there was no danger. It didn't take long for them to reach the first heavy water recharge station in the Streamer Layer.

Taking advantage of the gap in the fuel load, Tianxuan muttered to himself: "I don't know how long it will take to reach the main city of Maya!" ”

"It's about two days on the ground!" Sal said.

"Oh! Mr. Sal is not a long time, but how can we solve our food problem? Gotta find a restaurant! Tianxuan said and his stomach growled.

"Hehehe, rest assured, there is a party hall within 20 kilometers to that bag you are full!" Sal chuckled.

"Okay, let's get on our way!" Tianxuan

"Look at you, you've only been hungry for a few hours!" Hercules

"Eat a lot of fruits, put a few times in the water and it's gone! The hard rations can't hold up! "Tianxuan

"Hold on, rookie, it'll be there soon!" Hercules

The steady speed of the waterway pioneers was 40 kilometers per hour, so after more than 20 minutes, they saw a huge underground palace standing on the crystalline land, and the reflected light against the various magma crystals made the palace seem to be packaged as a fairytale building. The Maya's construction art is truly amazing, regardless of the structure, color, and light, they have completely taken into account the calculations, and it is unbelievable that the 3D renderings we render in 3DMAX in real life are incredible.

They gradually approached the transfer station, and they were about to eat, when suddenly the ground shook, and the five of them felt the world spinning.

"No, we can't go in, the transit station will be closed soon, we have to get out of here." Thrall shouted as he instructed the other four to turn around with him. Luckily, they slipped quickly, and within a few minutes, several magma pillars rose around the palace, just as they were beginning to turn around.

"Wow! It's dangerous! If we hadn't run fast, we would have become roast suckling pigs! Tianxuan breathed a long sigh of relief after speaking.

"What now? Mr. Sal! "Tianxuan

"Yes! Nothing is too much trouble! Let's go to the largest smelting base at this level first! There will be no closures due to earthquakes and magma eruptions! Sal said.

Then, Tianxuan and his group of five people turned the head of the car again and drove towards the smelting base in the southwest direction.
