Now Li Chen and his cultivation team are in the team, except for Jiang Yun, who is about to enter the second heaven of the day after tomorrow, Li Chengmin has been entering the ninth heaven of the day after tomorrow for a while.

The two sisters, Akiko Hiromi and Tomoko Hiromi, are also all at the peak of the Eight Heavens of the Day After Tomorrow, and are about to enter the level of the Nine Heavens of the Day After Tomorrow. Although Yang Linyi said that it was slower, with the assistance of the spiritual materials that Li Chen bought from the spiritual materials of Brother Mountain Spiritual Material Main Store, it had also stabilized in the Eight Heavens of the Day After Tomorrow.

Only Li Chen himself is still wandering in the realm of the Seven Heavens of the Day After Tomorrow, so everyone is not far from the goal of entering the Martian dungeon, Li Chen even suspects that Lin Zhi has successfully advanced to the innate realm, but he doesn't know how Xiao Hei's strength as a genetic war bear has improved, it should not have the bottleneck of physical ascension like himself.

All the women finally agreed with Li Chen's idea, and chose the destination of their escape at the entrance to the unknown passage in the northernmost part of the Third Estate.

Although he didn't know what was hidden there, so that the map of the third estate was not marked, and even the people of the third estate knew nothing about it, but since the map had already marked it, Li Chen could be sure that even if there was any special secret hidden there, it would definitely not be a secret related to survival, otherwise the Martians would definitely not let it be displayed on the map at all in order to hide it.

After determining the direction of progress, the team did not immediately return to the surface.

Because the abnormal energy fluctuations were detected when the armored engineering vehicle was passing under the ground, Li Chen simply let the armored engineering vehicle continue to dive to find the location of the abnormal energy fluctuations.

As long as that abnormal energy fluctuation was not nuclear radiation, or abnormal cosmic rays, it would be helpful to their cultivation.

Moreover, it should also be the most frequent time for the people of Miyue City to search the area between Miyue City and the Brother Mountain Range, and it is best for them to take advantage of this time to find the abnormal energy fluctuations underground and avoid the search of Miyue City by the way.

The source of the anomalous energy fluctuations was located about two kilometers underground, and with the speed of the armored engineering vehicles and the geological structure of the current Third Estate, it would take them at least a few days to reach the intended location.

And judging from the infrared images transmitted back by the engineering vehicle, Li Chen guessed that it should be a place where underground magma is active. The active underground magma is the real underground spiritual vein that supports the entire third level, as long as they can find the main location of the spiritual vein, then successfully advancing to the innate realm is just a matter of speed!

When the armored engineering vehicle was moving straight towards the abnormal energy underground, there was already a team sent by Miyue City on the grassland to find the mysterious monster.

Some of them also saw the huge pothole left by the armored engineering vehicle, and searched down the pit for a distance, but unfortunately, Li Chen had long thought that someone would follow down the hole they dug out, so when he dug down more than 20 meters of the hole, he had already blocked the hole dug by the armored engineering vehicle with solidified materials, and they went all the way down, and they also blocked the passage left by the cleared rock and soil all the way.

With the solidification and disguise of earth technology, there will be no Martian people who can judge from the surface traces of the cave entrance that there is actually a huge artificial object that has been drilled into the ground under the cave entrance.

Of course, the armored engineering vehicle uses nuclear energy when passing through the hole, and naturally it is impossible for the armored engineering vehicle to have any spiritual power residue due to the actions of the armored engineering vehicle. Therefore, this cave entrance failed to attract the attention of Miyue City at all, and the search team of Miyue City only searched this grassland at will and gave up the search here.

As for the two elders of the Brother Mountain Holy Land, after they returned to Miyue City that night, they did immediately inform the Brother Mountain Holy Land about the mysterious demon beast. Moreover, they had already described the reaction of the city lord of Miyue City in particular, and with the importance that Lin Mu attached to this demon beast, they could be sure that their previous estimate of the value of that demon beast was much lower.

Now the two of them couldn't even get the slightest bit of information about the mysterious demon beast from those people in Miyue City, which shows how much Lin Mu attached importance to the blockade of this news!

As for Li Chen and the others, who had already escaped from their palms, Elder Liu only sent special news to the branches of the Brother Mountain Holy Land in various cities, and did not let people go after Li Chen and the others.

Now is an important period for the Holy Land of Brother Mountain and Miyue City to secretly compete for the mysterious demon beast, and the escape of Li Chen and the others is no longer so important.

After Li Chen's engineering vehicle passed through the aquifer layer, the fossil layer, and the high-strength mineral layer, they finally approached the place where the abnormal energy fluctuations were heard on the seventh day of entering the formation.

And when they got here, the temperature of the formation had already shown that it had exceeded two hundred degrees Celsius, and fortunately they were all in armored engineering vehicles, otherwise Jiang Yun's current strength would definitely not be able to withstand this high temperature.

"It's decided! Here's the underground lava! Li Chen judged through the data of the armored engineering vehicle and the image signals sent back by the sensor that there was already a sea of magma under the stratum that was only more than 50 meters deep from them, and they did not dare to drive the engineering vehicle directly, even if it was a high-tech thing like an armored engineering vehicle, once it entered the sea of magma, there would be no return.

And even if they didn't see the magma sea below with their own eyes now, they had actually felt a rich aura emanating from the ground upwards, and that aura was not only fire spiritual power, it was an existence that contained almost all kinds of spiritual power.

Li Chen suspected that if these spiritual powers below continued to evolve, maybe they might even evolve into some kind of special divine power, just like they could extract the spiritual power they needed through the Martian divine power on the surface of Mars.

In this place nearly two thousand meters underground, generally speaking, even if they are powerhouses in the Sun Realm, their Divine Sense cannot scan in, because the complex environment in the stratum can easily interfere with their Divine Sense, even if their Divine Consciousness can expand for tens or hundreds of kilometers, when they look underground, they can only return a mess of information.

After coming to this place extremely close to the underground magma sea, Li Chen did not immediately stop and let the girls enter the cultivation state, he first used the armored engineering vehicle to open up a space of several hundred square meters in the horizontal direction, and then processed some solid insulation materials to create a temporary base, and drove the armored engineering vehicle into the base, this time the trip came to an end.
