The dragon vein hypothesis sounds a little reliable. If you want to test this, you only need to constantly probe underground.

    People in the fire shadow world have almost never tried this. Even in the real world, similar attempts only appear in science fiction. The deepest well drilled by man. It is only 12km, which is a negligible tunnel for the earth''s crust.

    However, that is because there is no need to drill down and there is no excellent technology to easily complete such exploration.

    Liu Tianxin is different. He has enough motivation. Dig a long and narrow tunnel to see what the inside of the planet looks like. Similarly, he also has enough black technology to deal with the high temperature and high pressure inside the planet.

    Even the construction scheme is ready-made. In the world of God III, volunteers have designed similar programs. It is the way of ladder transmission through offshore drilling platform. Reach the depths of the earth.

    However, it is obvious that this project will not be completed in a moment and a half, even with a large number of black technology. The diameter of the planet is there, and there is no time for ages. It is difficult to dig such a tunnel.

    "Ah... Speaking of it, it''s time for us to start archaeology." Chengying looks at the red dot on the map, which is the library where they check Douluo. After combining various clues. Possible ancient relics.

    Different experiences between Chengying and Liu Tianxin have proved that you are the same Douluo, and different worlds will have different development. Some are a whole universe, some are just a planet, wrapped in an eggshell, the same cosmic boundary.

    And want to know the setting of a world. In addition to exploring outside, the best way is to understand its history.

    As for how they read these books, people in this world are almost unprepared for machines without soul force fluctuation, so some detectors and monitors are very convenient to install.

    As for immoral things, can a scholar''s business be called stealing?

    "According to the historical records we have read at present, in this world, 10000 years ago, except for the people who became gods, there were two double biological souls in an older era.

    This is also recorded in the original work. When Tang San was practicing twin martial spirits, the master actually reminded him that he could wait for one first. After the martial soul rises to the ninth ring, give another martial soul, all of which are attached with high-level soul rings.

    But it also suggests the danger of doing so, which may lead to the death of the soul master. And clearly given the historical records, one of them exploded and died, while the other successfully obtained the soul ring. At that time, Tang San also came to a very scientific conclusion, that is, the mortality rate of adding a soul ring to the second martial soul is 50%... "The background explains.

    Yak took a swipe at the corner of his mouth: "don''t mention 50% of the questions. Do you mean that the site we found is probably left by the surviving or dead twin soul warrior.

    Logically speaking, in ancient times, there should be few twin martial spirits. Although we can be called twin martial spirits these days, many are like dogs. Shrek has seven people. It is true that there are 12 martial spirits in total, but according to historical records, this situation is extremely rare even in recent thousands of years.

    The twin martial spirits in ancient times should be more rare. Moreover, the general situation of your time, it is difficult to cultivate the second martial soul without the help of the divine throne.

    Although there are two worlds, different rules are possible. However, according to our statistics, even in the tulip era, with a population of hundreds of billions, the twin martial spirit is an extremely rare variation. The probability of occurrence is about one in 100000.

    According to our statistics, if these people do not carry out physical transformation, they will almost die if they cultivate the second martial spirit. In a sense, twin martial spirits should actually be a distortion, similar to human deformities or congenital bisexuals.

    Under natural conditions, this may even be a malignant variation. Therefore, even if the twins combine with each other, it is difficult to have the phenomenon of heredity.

    With this relatively clear data support, the ancient twin martial spirits are very likely to have a relationship with the gods. Even if they have no relationship, they must have relied on external forces.

    I prefer the latter. Because Tang San didn''t meet his fellow countrymen in the divine world. That is, he became God earlier than him. It is unlikely that the ancient twin martial soul person relied on the power of the gods. Of course, it may also be that during this period, the throne has been inherited more than once, but this possibility is smaller. "

    "HMM... me too. I have the same idea. That''s why I want to go to his ruins. Maybe he will leave some useful things. For example, what strength did he rely on to survive the twin martial spirit and collapse.

    On this continent, in addition to the power of the gods, even fairy grass can not help twins. The excessive growth of the body caused by the martial soul and soul ring is even more impossible for the people here.

    This may reveal the great secret of the Douluo continent. With luck, we may find the clue to the origin of soul power. "

    After the film is finished, the analysis will not continue. After downloading the map, the two left the underground base and drove the upgraded vehicle. Heading for the suspected ruins.

    They will believe that there are ancient relics here, not only because of the records in history books and folklore, but also because they have investigated the nearby villages. Has anything strange happened in this area?

    The valley they went to did have such strange places. For example, people who entered it would get lost and leave inexplicably. Or if someone falls asleep, he will somehow sleepwalk to the entrance of the valley. When he wakes up, he has soul power.

    There are many similar strange tales and legends. Not only good, but also bad. For example, someone entered the valley and never came out again. Or in the middle of the night, some monsters ran out of the valley and plundered the villagers'' livestock. Therefore, there were few people and some people dared to approach there.

    Most of these strange stories are fabricated or exaggerated descriptions, but with the help of lie detection equipment. It is certain that some strange talk is indeed the personal experience of some people.

    The car stopped at the southernmost end of the Xingluo Empire, near a desert, which is hot and dry. Already close to the equator, he was above the canyon, and the air was twisted by the hot sand. Many scholars explain the strange talk here as a mirage. But the truth is obviously not that simple.
