Wang Fugui began to operate the excavator and excavated the entrance of the underground space that had been explored and identified. Chen Jian and the others naturally surrounded him.

As long as the entrance to the underground space is dug up, they will enter as soon as possible.

While Wang Fugui was operating the excavator for excavation, Chen Jian looked around. Fortunately, this season was when crops were growing. The lush crops blocked people's sight. Although this excavation site was not in the fiefdom, it was not easy to find.

In addition, there is a small forest on the other side, although it is not big, but it also serves as a blocking view.

Such an environment is very helpful for the alert work of the Thunder Dragon Group. If you cannot see the Thunder Dragon Group, it is also related to the surrounding environment. They must have brought people to hide their bodies.

As for the fact that this area is an open land, it is actually very easy to understand, because this area still belongs to the Sanxingdui cultural site, and it is difficult to ensure that there will be no cultural relics buried deep. Nearby villagers are still allowed to plant crops and use them as arable land. It is very likely that cultural relics will be unearthed when farming, which can easily lead to the loss of cultural relics.

The excavator driven by Wang Fugui is a small excavator. Although the work efficiency is slower than that of large excavators, the advantage is that the small excavator is easy to move, and the road to this place is not wide, and there are some dirt roads, so small excavators are easier to pass through.

Next is this underground space. Although Chen Jian and the others will go down, they have no idea of ​​excavating cultural relics and archaeology. After Chen Jian and the others come out, they may still bury them again. Small excavators only need to excavate the import and import, and do not need to dig too much space.

The only disadvantage is that the working efficiency of small excavators is slightly slower.

Wang Fugui's driving operation skills are still very good. He dug more than two meters shortly after, which was nearly three meters deep. However, Wang Fugui was operating the excavator, digging out a shovel of soil, and pouring it on one side, but stopped, jumped out of the excavator's cab, and quickly walked to the vicinity of the pit that he had dug out before.

Chen Jian and the others looked at each other and immediately followed him.

Wang Fugui didn't say much, but pointed to the pit below.

Chen Jian and the others looked into the pit and saw that the soil inside was a little different.

"Engineering shovel!" Chen Jian said without hesitation.

Xiao Yurou ran back to the tent, took the engineer shovel back, and handed it to Chen Jian.

Chen Jian jumped directly into the pit and used engineers to clean up the soil inside. Soon, the soil was cleaned up, revealing the shape of the steps.

This step is also a soil staircase, but because it has been artificially treated, it is very different from the surrounding soil, just like the rammed earth foundation of the Sanxingdui site that has been excavated.

Chen Jian came out of the pit and looked around.

Wang Fugui chose to dig the site, not the entrance, but the excavation was only started after retreating a little distance.

Because this small excavator cannot dig a depth of six meters in a straight line, it is necessary to retreat some distance to start digging and gradually deepen. Once it reaches the entrance to explore, it can dig to a depth of about six meters.

At this time, the steps were dug out. Chen Jian pondered for a moment and said, "The steps should go straight to the entrance. From this we can see that the more we go to the entrance, the steps are downward, and in the opposite direction, it is upward. From the highest point to the lowest point, the total depth of the steps is shown. You only need to dig out the highest point and you can measure it."

"Don't worry about those, keep digging!" Xuan Mingzi said at this time: "But be careful, these steps are also cultural relics, so try not to destroy them."

Chen Jian looked at Wang Fugui, Wang Fugui nodded and said, "I have a clear idea!"

After Wang Fugui said this, he returned to the excavator again. After Chen Jian and the others pushed it away, Wang Fugui started digging again. However, this time Wang Fugui went around to the other side to dig, which was to excavate on one side of this step, destroying the steps.

Chen Jian just entered the pit and used an engineer to clean it up, and had already cleared a complete step. The step was about two meters long and had a width of about forty centimeters.

The cleared step becomes a reference object. Wang Fugui can avoid destroying other steps as he continues to dig according to the size of the step.

However, this leads to the slower digging speed.

When Wang Fugui digs for a while, he will stop. Chen Jian will hold the engineer shovel in his hand again, enter the pit, clear some steps out, and let Wang Fugui use a reference to continue digging with an excavator.

After repeated this, the remaining three meters of depth was digged in an oblique manner. After the thorough excavation was completed, many steps were cleared out.

There are four construction lighting lamps on the excavator. While excavating in place, Wang Fugui drove the excavator backed a little distance, allowing the lights of the construction lighting lamps, which are like searchlights, to shine on the excavated place, that is, the entrance area.

Two stone doors appeared before everyone’s eyes!

These two stone doors are about three meters high and two meters wide. When you stand on the height above, you feel very magnificent!

The two stone doors were closed tightly at this time, which gave people a feeling of being very tight. In fact, it was true. The junction between the two stone doors was really tight!

The thickness of such two tall stone doors is still unknown, so if you want to push them open by man, it may not work.

Wang Fugui took the engineer shovel in Chen Jian's hand, walked down the first place, and knocked on the stone door with the end of the engineer shovel.

The echo is dull, which means that the stone door is very thick.

"Explode?" Xiao Yurou asked in a low voice.

"You are crazy?" After hearing Xiao Yurou's words, Wang Fugui turned his head and looked at Xiao Yurou, and said, "You must not be able to push such a big stone door, and there must be mechanisms!"

After Wang Fugui said this, he started digging the soil next to the stone door on the right with an engineer shovel.

"Why don't you dig here?" Xiao Yurou asked.

"Silly woman, do you open the door with your right hand or your left hand?" Wang Fugui said while digging: "This is common sense!"

"I'm a left-handed!" Xiao Yurou said as if she raised her argument.

Chen Jian smiled and shook his head. Left-handed people are the minority after all. Wang Fugui is right. There are still many people using their right hand. If there is really a mechanism, it should be on the right hand.

Moreover, Wang Fugui is also selective in the height of the soil excavation, which is about 1.34 meters as the center point, and then it expands upward and downward, each expanding thirty centimeters!

With a "clang" sound, the engineer shovel hit a hard object. Wang Fugui grinned and said, "Finish it!"
Chapter completed!
