The starting point of the line on the circuit diagram is the stone chamber where it is located, and the end point is the center of the entire great circle. Pen, fun, and www.biquge.info

Chen Feng was puzzled: "What do you mean?" ”

"Open the hole."

"Inside the crater?"

Xu Mengyi nodded and put on a teachable posture, explaining: "We directly open a passage to the inside of the crater, if the inside of the crater is empty, we can go down the crater to the foot of the mountain, and then dig a passage horizontally below, maybe we can enter the stone chamber below." ”

Chen Feng objected: "The volcano is buried under the surface, how can it be empty inside, if it is a dormant volcano, we will hit the magma, it is better to dig directly down where we are now." ”

Xu Mengyi looked at the east side of the stone chamber, that is, the direction of the inside of the crater, compared with the road map, and said, "Dafeng, don't you think there is a problem here?" Why do these stone chambers and clear water spiral around the volcano? This situation is not obvious to say that the important place is inside the volcano. ”

"Do you have a basis for this habitual thinking?"

Xu Mengyi shook his head like a rattle, and simply said: "Anyway, I don't know the distance from here to the foot of the mountain now, and the food we bring is not enough, try it, according to the diameter of the mountain pass here you said, it will take a day and a half to dig into it." ”

"What if you hit lava?"

"Magma is hot, we can pay attention to the temperature of the rock in real time, and if the temperature rises, then stop."

"I want to think about it."

Chen Feng pondered for a moment on the road map, then walked to the rock wall on the east side of the stone chamber, looked back at the passages in the north, south, and west directions, and closed his eyes and roughly recalled the location of the passages in the stone chambers.

It seems that none of the passages are facing the center of the volcano, and one wonders if the stone chamber deliberately kept people from getting close to the center of the volcano.

Chen Feng contacted Wang Yi for this and gave him an explanation of the newly discovered situation to understand his opinion.

"It's hard to analyze, there's no clue." Wang Yi said in the newsletter.

"Just follow your instincts like this." Xu Mengyi interjected.

None of them knew what to do, and they were silent and thoughtful.

After a while, Chen Feng spoke: "It is safer to continue to follow the direction of the water flow to find the source, that is, the road may be a little longer, if you drive towards the center of the volcano, you may not be rewarded, and you may waste time, this is a rational analysis." ”

Wang Yi heard that he deliberately added the word "rational", so he still had irrational thoughts, so he guessed: "So Brother Feng, you intuitively agree with Brother Xu's proposal?" ”

"Sort of, I don't know if I've also developed habitual thinking."

"Okay, it's a multiple-choice question again, I think there are two ways to deal with this kind of thing, one is to rely on intuition, and the other is to draw lots, you can choose."

Chen Feng and Xu Mengyi discussed and discussed, and jointly decided to draw lots, and if there was a mistake in judgment, they would not blame themselves, and God was to blame.

Xu Mengyi got two stones of different sizes, the big one was a hole, and the small one was to move forward the same way, and held it in his hand for Chen Feng to choose.

When Chen Feng was chosen, Xu Mengyi opened his fist to reveal the small stone, and immediately clenched his fist again, saying that he wanted to win two out of three games.

Chen Feng chose a large rock in the next two guesses, but he always felt that the expression on Xu Mengyi's face seemed to be a ghost, but to be honest, he also wanted to see what was going on there, and finally agreed to dig a tunnel.

The specific direction of the excavation is easy to determine, relying on the road map drawn and the direction of the holographic computer, even if it deviates, it should not be too far.

Four groups of silent whisperers were assigned new tasks by Chen Feng, two groups took turns digging passages, and the other two groups were responsible for guarding.

The excavated rubble had been transported to the stone chambers that had been walked before, and some markings had been rearranged in the adjacent stone chambers, if the creature hiding in the shadows could clean it up, or if it could be found.

The team stopped moving forward because of the excavation of the passage, and Xu Mengyi, one of them, took this opportunity to re-analyze the situation here with Wang Yi, and by the way, learned about the progress on his side.

The construction of the battle armor and the excavation of the transportation channel were still going well, and the two beehives in the sky fell again yesterday evening, and the bombardment lasted for nearly half an hour.

The Vajra base, which had long been buried in the ground, was baptized again by the flaming spear, and all the ammunition inside had been detonated, and before that, a total of 2,813 rockets had been rescued from it.

Wang Yi is still ready to counterattack the hive, and he will use less than 3,000 rockets as the main attack, but compared to before, he will make some slight adjustments to the plan.

The previous plan was to dig up more rockets from the base and then launch a saturation attack on the hive, but at this time the amount of ammunition was less than a quarter of the original plan, and the power of the rockets had to be considered.

Wang Yi wasn't too anxious about the things on his side, and he didn't say too much to Xu Mengyi, just asked them to pay more attention to safety, and the other was to briefly describe the situation on their side.

Ma Yuanliang and the others have launched 10 investigations in Ningxian City since yesterday, basically two times in the morning, noon and evening, and two times after midnight.

Each reconnaissance is a group of five people, four to five groups of people act at the same time, when five groups of people are dispatched, one group is at high altitude, and those who do not have a reconnaissance task are on guard in a square bunker.

The first three reconnaissances were all carried out in a stealth way, infiltrating in four directions of Ningxian City at the same time, but they were discovered by the winged snake before they did not reconnoiter far, and the result was a big battle.

Since the failure of the first three investigations, Ma Yuanliang changed all the follow-up investigations to violent methods, and went straight to the center of Ningxian, and the last investigation successfully hit the Fourth Ring Road.

At this time, Ma Yuanliang was enjoying lunch and preparing for the next investigation.

Wang Yi has been paying attention to the situation on Ma Yuanliang's side, the research and development of their mechanical defense cover is the top priority, and after the call with Xu Mengyi, he contacted Ma Yuanliang again, and seeing that the sun was shining on his side, he couldn't help but say: "Oh, yes, it's still sunbathing." ”

", can you sweat in the bath?"

"Sweat a lot and get better."

"You're sweating, don't talk about it, you don't have the heart to joke." Ma Yuanliang began to transmit all the current investigation information to Wang Yi, and then said: "Help the staff and staff, see what is wrong with Ningxian City, uncle, this winged snake is really a wholesale product, no matter how you kill it." ”

"Didn't you kill in the Fourth Ring Road, the industrial area you are going to is outside the Fourth Ring Road, and you still kill inside? Propped? (To be continued.) )
