The anaconda's body was constantly twisting, and judging from its physical condition, it was obviously painful.

Lu Yuanxin mentioned his throat and eyes, for fear that his body would not be able to withstand the huge energy and burst.

Fortunately, although the whole process looked scary, it managed to survive.

After two hours, the python finally quieted down.

Lu Yuan found through his divine sense that in just two hours, the anaconda's body had grown by one centimeter, and its body had become a little thicker.

Lu Yuan grabbed the python with his hand and felt the power of the python.

After this toss just now, the power of the anaconda has also become a little greater.

"It seems that the meat of the king squid is really effective against the anaconda!"

"Maybe it really works wonders if you keep feeding!"

Lu Yuan's heart was overjoyed.

He was now considering whether to feed the anaconda with the meat of the king squid all the time.

As a Zhuxia person, Lu Yuan's thoughts naturally did not lack the dragon complex.

He really wanted to know if the snake could really evolve into a dragon.

Lu Yuan seems that there is still a lot of meat in the king squid anyway, and it is not of much use to himself now.

It's better to do an experiment than to waste it, even if the anaconda can't evolve into a dragon in the end, it doesn't matter.

Lu Yuan continued to observe the situation of the anaconda, and found no problems, so he left the space.

After returning to the tunnel, Lu Yuan continued to walk.

This tunnel is deeper and longer than Lu Yuan imagined.

The further you go inside, the more and more various forks in the road.

Along the way, Lu Yuan also picked up two tools.

The materials of these two tools are also not ordinary, one is made of jade, and the other is made of obsidian.

The use of jade to make tools has always had this tradition in Zhuxia.

From time to time, the archaeological community has unearthed some tools made of jade.

According to the ancient books of Zhuxia, the ancients believed that jade tools must be used when digging or making special things.

Therefore, although the jade tools were precious, Lu Yuan was not surprised.

On the contrary, it was the obsidian tool that appeared here, and this was what really surprised Lu Yuan.

Obsidian, also known as dragon crystal and Shisheng stone in Zhuxia, is a common amorphous gemstone and volcanic crystal.

Its main ingredient is silica, which is usually black in color.

Because of the characteristics of glass, obsidian has a shell-like fracture after being broken, which is very sharp.

Today, most of the obsidian jewelry is produced in the Middle and North regions, and the national stone of Mexico is obsidian.

Obsidian is also produced in the Tibetan region of Zhuxiaus. In Zhuxia, obsidian has been used as a ward off evil spirits and amulets since ancient times.

When he was in Mizhou before, Lu Yuan had also found some obsidian tools.

It is naturally not surprising that Lu Yuan found obsidian tools in Mizhou, because as long as anyone who knows a little about Mizhou knows.

The main specialty of the three empires of Rice Island is obsidian, and most of their weapons and tools for daily production are made of obsidian.

But it is different in Zhuxia, where there is very little obsidian production.

Although obsidian is also produced in the Wusi-Tibetan area, the yield is not high, and the transportation is also very inconvenient.

Since ancient times, obsidian in Zhuxia has been a very precious existence.

Obsidian products are generally only found in royalty and families.

Moreover, these obsidian stones are also made into handicrafts or ritual weapons, and things that are attached to amulets.

The use of obsidian as a tool was unheard of before that.

And judging by the traces on the two tools, it is clear that these two tools have been used for a long time. Not an ornament at all.

Lu Yuan deduced in his heart that what this pit was going to excavate was definitely not the ore he thought before.

At least not an ore in the traditional sense, otherwise such a precious jade and obsidian tool would not have been used.

And there are no common ores seen along the way.

If the excavation is a conventional ore, even if it is a hollowed-out mine, it will not be so clean.

So what exactly is being excavated in this mine?

Lu Yuan began to diverge his thinking.

Since it is not a mineral in the traditional sense of the word, what needs to be mined with a jade or obsidian tool?

At this time, Lu Yuan began to think of myths and legends.

In Zhuxia, body poison, ancient Babylon, ancient Egypt, and ancient Greek myths and legends, a stone containing great energy is mentioned.

Although the names are different in the legends of different civilizations, from the description point of view, they should refer to the same thing.

In fact, this thing is not unfamiliar to friends who like to read Xianxia novels.

It is similar to the Spirit Stone in the novel, but it is not exactly the same as the Spirit Stone.

These stones, which contain great energy, cannot be used directly, nor can they be directly absorbed by the human body as in the novel.

It is used in a similar way to modern nuclear materials and can only be used by means of special instruments and methods.

When Lu Yuan was studying the myths of various countries, he also noticed this kind of thing, but he had never seen the real thing.

At this time, Lu Yuan suddenly thought that he had seen a lot of mysterious stone powder along the way.

Could this powder be the remains of this "spirit stone" after losing its energy?

In the previous exploration, Lu Yuan already knew that the earth had undergone great changes, and the energy on the earth had escaped in large quantities.

When a large amount of earth's energy escapes, do these "spirit stones" also have energy escape?

In the end, the pit was abandoned!

Lu Yuan felt that this was very possible, in Lu Yuan's opinion, except for the "Spirit Stone" mine, other mines would not appear in the current situation.

However, Lu Yuan quickly frowned again.

"Now that the pit has been abandoned, why is it still marked on the map left by the Teotihuacans?"

"Could it be that there are still some things stored in this mine, and there are still things left over from the time of the evacuation!"

Thinking of this, Lu Yuan couldn't help but get excited again.

It would be great if there really was something left.

In Lu Yuan's opinion, no matter what it is, as long as it has a relationship with ancient civilization, it must be a good thing.

Lu Yuan rested for a while, got up and continued to walk deeper into the mine.

Along the way, he found some tools left over from the original excavation of the pit.

Of course, these tools are also not metalwork.

It's not all jade and obsidian, though.

He also picked up a shovel made of crystal.

Judging from the texture and production process of the crystal, it is similar to the batch of crystal products found in the Green Ridge.

Lu Yuan put away these things and continued to move forward, and soon after that, a door appeared in front of him......
