Pure gold proved to be impossible, of course, but the materials used in this construction were even more intimidating than pure gold, as it was constructed from a single piece of soul gold.

What is Soul Gold? Soul gold is to crush and compress the soul of a living body according to the way of energy compression, and finally when this soul body is condensed to the point where it can no longer be compressed at all, if the pressure continues to be exerted and exceeds a certain critical point, the soul that originally had no entity will suddenly undergo a state transformation, "instantly changing from an invisible substance to a tangible substance", and this physical substance is soul gold.

Since soul gold is something compressed by the soul, its essence is actually the soul, and the soul is a very dense energy body. However, "although the energy density of the soul is very high", the compression ratio required to turn it into soul gold is absolutely amazing. An ordinary person who has not undergone any training, after his soul is completely condensed into soul gold, can probably form a soul gold the size of dust. If the Seven Heroes Tomb in front of him was completely compressed from the souls of ordinary people, then it would be useless to kill all the low-level creatures in the world, because the energy was simply not enough.

However, the yield of soul gold actually has little to do with the number of souls that are compressed, and what really determines the output should be the soul strength. In the game, this kind of soul strength is generally linked to the level, of course, the strength of different races will be different, for example, the soul strength of undead creatures is generally higher than that of other creatures, after all, people have nothing else but souls, and it is impossible to become an undead if the soul is not strong.

Although the soul of a high-level lifeform can produce a larger volume of soul gold after compression, even if it is the number one in the combat power list like me, or the Jade Emperor, the Great Sun Rulai, or even Anubis, the volume of their soul after compression will definitely not exceed the original volume of their soul. In other words, even if Anubis's soul is compressed into soul gold, its volume will definitely not be larger than the current Anubis.

The yield of soul gold is so low, and the building in front of you is so big, how many souls do you have to use to press out such a large piece of soul gold? After figuring out the structure of this thing, I was almost stunned by what I found, it was like someone going to climb a mountain on the weekend, and it was like accidentally discovering that the whole mountain was a whole diamond except for the outer layer of soil, and this shock would definitely break most people on the spot.

"This, this, this...... How did you get this thing in the first place......" Looking at that Seven Heroes Mound, I started to tremble even when I spoke.

The national teacher skeleton explained, "Actually, we don't know where this thing came about. We just discovered this underground space at the beginning, and then found soul gold fragments all over the cavern here. After that, we used the magic circle to fuse the shattered soul gold fragments together, and then made this Seven Heroes Tomb ......."

"You mean this thing is a natural ......"

"Isn't that ......," replied the Skeleton Master, "we didn't know what it was like in the first place. It seems that the cattle from a nearby farmer first fell into a hole in the ground, "and then the villagers came down here to look for cattle." However, at that time, the foolish people didn't know the value of soul gold, but they just thought that this thing was very beautiful and shiny and gave it to the local nobles. The nobleman took this item and forwarded it to the monarch, and then my master found the soul gold from the monarch and explained the origin of this thing to the monarch......"

"And then ......"

"And then, of course, the monarch wanted to mine it on a large scale. However, when the master and the king's men arrived, "the people in the village were gone, and the team that came was attacked by a large number of demons......

Although the national teacher's words are not finished, "But I already understand the reason." "With the strength of ordinary people's souls, "if you come into contact with soul crystals of such a high purity every day, you will only have ghosts if you don't change ......"

"The adults are really smart...... the national teacher did not forget to pat his ass: "Things are just like the adults guessed." The monsters were later confirmed to be all by local villagers, and some half-human, half-demon monsters were found during the raid of the village.

Later, we learned that those half-human, half-demon monsters were actually villagers whose soul power was too weak to withstand the power of soul gold and could not be completely demonized. Later, Master and the others learned about the process of soul gold turning people into demons from the half-human, half-demon villagers, and the half-demonized villagers asked to help them end their suffering, so the king sent someone to help them understand life and set up a public cemetery for their burial. However, when the team sent by the monarch returned to the palace with the news, they heard that there were youkai in the palace. My master immediately thought of the soul gold that must have been caused by the tribute, and it turned out that the monster was one of the king's favorite concubines. The tribute soul gold was given to the pet by the monarch as a gift because he had never understood the purpose, but the pet Ji held the soul gold every day and played with it, thus absorbing too much soul power and guiding the spirit to lose control and become a demon. ”

"Is it because of that demonic good thing that the king ordered this place to be sealed......

"That's what ...... claimed to be to the outside world"

"Externally?" "Actually, it's not as good as it is. At that time, there were indeed demons in the palace, but not just one, but one dish. Among them, in addition to the favorite concubine, there are two lower daughters and Her Royal Highness the little princess......"

"With so many people becoming demons, the monarch should be even more angry, right? Why is it said that it is so horseshoe crab to the outside world? The monarch had a reason to be angry and seal the soul gold. "There is indeed such a reason to exist zài", but the king only uses this as an excuse to ......"

"Why ......"

"Because when my master rushed back to the palace, only three of those demons were killed, and one demon did not die. At first, because he simply thought it was a demon rebellion, the guard goalkeeper killed the other three demons. But the master happened to rush back at this time" and informed the monarch that the demon may have been changed by someone in the palace. Knowing this, the monarch ordered that the last demon should not be harmed, but in order to prevent the demon from hurting people, he still caught and locked him up. After that, the palace carefully checked the identities of the missing people and those who died at the hands of the demons, and finally confirmed the origin of the four demons, and confirmed that the demon was actually the king's favorite little princess......"

"And then ......"

Then the monarch was very painful, and he didn't know it before, but after knowing that this demon was his favorite daughter, he couldn't bear to do it. Later, when my master saw that the monarch really couldn't make up his mind, he came up with an idea to let the monarch announce that the little princess had died at the hands of demons, and then secretly hide the demons that the little princess had become......

"What about the result......"

As a result, the monarch accepted the master's advice and made some minor adjustments. The monarch announced to the public that the appearance of demons was because the soul gold was ominous, so he classified this thing as an evil thing, and ordered no one to touch it, and once it was discovered, it was immediately sealed and buried deeply. This place where a large amount of soul gold has been piled up has also been sealed. In fact, the place we are in did not need to enter through the entrance we dug before, but directly to the outside. The top of this place was sealed by the king, and the passage we dug was built later, "for the purpose of secretly building the Seven Heroes Tomb after sealing the entrance, and sealing the remaining soul gold."

However, when sealing the soul gold, the monarch found that the little princess who had become a demon actually liked to touch the soul gold very much, "so the monarch felt that even if the little princess was imprisoned, it should make her less painful." So in the end, the monarch asked the master to find a way to melt the soul gold, and built this Seven Heroes Tomb with the soul gold, and sealed the little princess in the tomb......"

"What? Is this a prison? "Almost......" The national teacher said: "Actually, I was just born when the monarch ordered the closure of this place, and then I was picked up by the master and raised in the process of following the master to move here, and after the death of the master, the task here was handed over to me, during which the monarch also changed three times, but because the later monarchs knew the inside story of this, they all insisted on completing this building" After all, no one would use soul gold at that time, only knew that this thing could create monsters. Such a hoodoo is naturally good to be sealed. ","...... That's not right......"

"What's wrong...... "As soon as the national teacher heard that I was wrong, he immediately became nervous.

"Soul gold is a high-concentration soul crystal, and ordinary people will become monsters because their souls can't control the absorbed soul energy after a long period of contact. Your laborers here are all ordinary people, and if you have been building the Seven Male Mounds made of soul gold here for a long time, isn't that equivalent to being exposed to the soul gold for a long time? You said before that the laborers multiplied here for two generations, "Could it be that the ones that bred later were all youkai?" "My lord is really smart...... "The national teacher patted his ass again, and said: "At the beginning, my master found a way to temporarily suppress the influence of soul gold on people," and it can strengthen people's soul strength in a small amount. Adults, you should also know that when the soul is strong, the ability to control the soul energy will be enhanced, "The possibility of becoming a monster will decrease, and the medicine we have configured has the effect of suppressing zuò, so basically the labor has no effect." However, what we didn't expect was that although the first generation of conscripted laborers did not change under the double protection, a high proportion of their descendants appeared deformities, some of them were born with horns on their heads, and some had scales on some areas of their bodies, in short, three or four out of ten children were a little abnormal. In the third generation, there are even more problems, many children are born with mutations all over their bodies, and some children are fine at first, but after a few months they start to change. For example, there is a child who looks normal at first, but after only half a year of birth, he has grown to the size of a normal child in his teens, and he is infinitely powerful. After that, all kinds of messy abilities also appeared, which is why the monarch took away all the children of the third generation. In fact, those children were carefully supervised after that, and if there was a problem, they would be killed immediately. Later, our country produced several generals who were enemies of 10,000 people, but they were actually selected from among these children. They don't change much on the surface, but in fact, they are invulnerable, which is why they are so ......."

"I really didn't expect there to be so many secrets in the Ichihua Male Mound!" As I was talking, my face suddenly changed. "Wait, no." "What's going on?" The national teacher was taken aback by me. In his opinion, I am already a very strong person, but my face suddenly turned blue just now, "Even I am scared like this, how can he not be nervous?" "My lord, what do you have in mind? Scared like this......"
