The reason why a temporary base was built was not to show that Li Chen had not forgotten his skills in building a base with armored engineering vehicles.

It's just that an armored engineering vehicle is just a car after all, and although the space in it is barely enough for everyone to move, it is not spacious enough after all. For practice, in fact, having a comfortable and happy mood is also a great help to improve the efficiency of practice.

After all, no one wants to stay in a cockpit with a size of only a dozen square meters all the time, even if they practice meditation, how can they calm down and practice without a comfortable and peaceful environment.

In fact, if Li Chen was just here, he wouldn't need to build this temporary base at all, his physical strength and cell activity were enough for him to survive in the space of more than two hundred degrees.

And the four daughters of Li Chengmin can also rely on the protective film condensed by their spiritual power in the body to resist the erosion of high temperatures. It's a pity that Jiang Yun's spiritual power can't provide her with enough protection.

In other words, the construction of this temporary base is simply a shelter specially built by Li Chen for his apprentices. In the case of not being able to withstand the high temperature, Jiang Yun only needs to stay in the shelter and quietly absorb the spiritual power. Li Chen would not force her to cultivate to the innate realm as soon as possible.

After all, Jiang Yun is not an earthling, she does not have the hunger and thirst of the earthling's physical spiritual power, she can only improve her strength step by step.

Li Chen had actually already decided in his heart that he would entrust Jiang Yun to the No. 5 base when he returned to the surface of Mars after all the people in their cultivation team reached the innate realm, and with Liu Yu's relationship with the No. 1 base, he believed that no one should really embarrass the No. 5 base, and Jiang Yun could be said to be safe to stay there.

In the space two thousand meters below the third level, it may be tens of thousands of meters away from the surface of Mars. Li Chen was the first to walk out of this temporary base, his cultivation was the lowest in the cultivation team, and now he couldn't afford to waste more time, and the current environment was also the cultivation environment he needed the most.

As soon as he left the temporary base, a wave of heat came to his face, and Li Chen only felt that the pores of his whole body were opening up in an instant, and the vicious heat drilled into his body along his pores.

He is not Li Chengmin and the other women who have spiritual power to protect their bodies, he has to bear and endure the high temperature of hundreds of degrees in this formation with his physical body.

Of course, the heat wave that drilled into his pores naturally also had a huge amount of spiritual power unique to this underground world. Through the light shining from the temporary base, Li Chen could see that the strata and soil on the periphery of the temporary base were all the same red as the soil on the surface of Mars.

Li Chen had already planned for this cultivation in this underground when he began to go down. He will leave the women near this temporary base, and then leave the armored engineering vehicle here, and there is a food synthesis device in the armored engineering vehicle to provide the daily necessities of the women.

And he prepared enough water and supplies in the space ring in advance, he had to approach the area of the magma sea below alone, the temperature and aura concentration here were not the limit he could bear, he had to practice hard near the limit of what he could bear, so that his body could accelerate the absorption of the newly integrated energy in his body, so that he could quickly approach the other women of the cultivation team in the realm.

As for Li Chengmin and the other women, just relying on spiritual power to form protection on the surface of the body, staying at this temperature is already a great consumption, and in the current environment, they will replace the spiritual power in the body with the spiritual energy outside the body to the greatest extent.

The rapid circulation of spiritual power will broaden their meridians in an efficient and fast way, allowing them to absorb the spiritual power around them faster, and subtly make their strength steadily improve.

This is actually the benefit of them as earthlings, the thirsty body meridians and cells and bones have long been thirsty for all kinds of spiritual power, and the speed of their absorption of spiritual power can easily break through the bottleneck that they are easy to encounter in the low realm, as long as they can be in an area with high spiritual power concentration, it is inevitable to advance steadily and quickly.

Moreover, according to the news and inferences given by Murong Zhilan, as long as they are earthling, after contacting the cultivation, if the exercises are not bad, there will generally be no bottlenecks before reaching the Taiyin realm.

Of course, Li Chen, who has already chosen to take the path of physical body cultivation, is of course not among them, if you want to ensure the stability of physical body cultivation, you must keep physical body practice and spiritual power cultivation to the same level, so that the body will not gradually rely on the strength of spiritual power in daily life, and ignore the importance of your own physical body.

After Li Chen waved goodbye to the five women in the temporary base at the edge of this space that had been carved out, he put on the extremely heavy tungsten gold battle armor again, and the gloves of the battle armor were also fitted with sharp finger sleeves on his gloves.

He just had to rely on this heavy armor to dig into the area where the magma sea below was located!

Although the vertical height of the magma sea from his current position was only about fifty meters deep, it was impossible for Li Chen to dig a fifty-meter shaft directly downward, he still had to come back to this temporary base at any time, he couldn't fly, once his physical strength was exhausted below, it would not be so easy to climb the shaft of more than fifty meters.

Like a pangolin, Li Chen excavated underground, digging at an angle of 30 degrees to the ground, which meant that he only needed to dig 100 meters diagonally to reach the predetermined position.

His arms staggered like electric fans, and the solid underground rock layer beneath his tungsten armor was like ordinary soil, and he easily carved out a passage for one person to pass through.

However, with the sharpness of the sharp fingers attached to the tungsten gold battle armor, Li Chen's speed in the land should not be able to catch up with those creatures such as marmots and pangolins that live in the soil all year round, and it took him a whole day to advance diagonally down about fifty meters.

Since this area is already very close to the underground magma sea, the temperature of the surface of the strata is getting higher and higher, and these strata have been eroded by high temperatures all year round, and the area near the temporary base above may not be very solid, but by the place below and closer to the lava sea, it has actually evolved into a solid rock structure again.

Even with Li Chen's current strength realm and physical strength, it is extremely difficult to move forward!

For now, he can only stop there.
