C905

Xiong Yu simply drew a topographic map on the ground and solemnly said, "the good news is that I have probably calculated the location of the underground river. The bad news is that the nearest straight-line distance between the underground river and us is 500 meters

As he spoke, Xiong Yu simply marked out their position with the underground river on the topographic map.

Sun Lanxiu frowned, shook his head and said, "we only have seven grenades now. We can't blow a distance of 500 meters."

Xiong Yu pondered for a while, and said with a smile: "that's not necessarily. Listen to my command. I'm 70% sure that I can walk into the dark river."

"What plan do you have?" Sun Lan said suspiciously

Xiong Yu pointed to the entrance of the cave and said, "first move the stones that can be moved at the entrance of the cave. How many stones can be moved? We will explode the big stones that can not be moved. The first step we need to do now is to collect grenades near the entrance of the cave 20 meters away. When the cave collapses, there are many people of the waden family who have been killed and their bombs Can be recycled. "

Sun LAN recalled the scene before the explosion. He also remembered that the mountain collapsed. When the waden family saw the lava in front of the volcano, many people began to run back in confusion.

According to the situation at that time, there were indeed many Walden family members who were killed by smashing around their location.

Xiong Yu didn't speak any more. He went straight to the entrance of the cave and began to clean up and remove some stones blocked in the cave. Most of them could be moved because they were fallen from the top of the cave.

Sun LAN and Wang Yunxiu also came to help with the move, but Xiong Yu turned to Wang Yunxiu and said, "don't do these rough jobs. You haven't practiced martial arts. You're weak. Try to conserve your physical strength. Once we get to the underground river and swim across it, we'll consume a lot of physical strength. You can't stand it."

Wang Yunxiu is also a smart woman. After listening to Xiong Yu's words, she stopped and sat in a place to have a quiet rest. She was very clear that her rest was the greatest help to Xiong Yu.

Xiong Yu and sun LAN cleaned up the rocks at the entrance of the cave very quickly, and then they began to clear the stones along the direction of the cave that had collapsed.

However, after clearing about four meters, they found that there was a stone of about 10 tons, which blocked the whole cave.

When the cave collapses, there are big stones and small stones. When you encounter such a huge falling rock, you can only use grenades to blow them up before passing through.

Without hesitation, Xiong Yu directly took out two grenades, tied them together, put them in a loose place of the big rock, and then detonated it.

Sun LAN asked: "why do you use two grenades directly?"

Xiong Yu pointed to the gap in front of the huge stone that was only blasted out of it. He said, "if you only use one, you may not be able to blast this stone at all. It's better to use two of them together."

After the big rock was blasted, the road behind it was much smoother, and it was ten meters ahead. There was hardly any big trouble.

After walking about 13 meters, they finally met the first person of the Walden family who was killed by smashing. Xiong Yu found five grenades from him.

Xiong Yu frowned and relaxed a little, and said, "if I'm not wrong, everyone in the waden family should be equipped with six grenades. When they got to the island, they used a few grenades when they met the Huahong poisonous snake, but none of them were used. Therefore, there should be four or five left in each of the Walden family who were killed One. "

Sun LAN didn't refute Xiong Yu's words this time, which is similar to her guess.

They continued to clear the rocks in the cave and continued to search for them. From the time they met the first person of the Walden family who was killed, there were more bodies in the back. About 20 meters ahead, Xiong Yu had collected 74 grenades. With the remaining five, there were 79 grenades in total.

Xiong Yu calculated the number of grenades and shook his head. It was still not enough. They were 500 meters away from the underground river. Moreover, it was a straight-line distance. All the bombs needed to be blown out.

Xiong Yu continued to look forward, and then 15 meters forward, and found 51 bombs.

Xiong Yu stopped, gasped a few times, said: "almost, and then go forward, you may not be able to find many."

Sun Lan said: "if it is a straight line of 500 meters, a bomb can blow out about two meters. We need more than 200 bombs to get to the side of the river."

Xiong Yu shook his head and said, "we don't have to blow all the way back. According to the topographic map I just drew, we can walk 400 meters east along the previously collapsed cave, and then blow up a passage with the bomb. In this way, we can save a lot of grenades."

Sun Lan thought about the map Xiong Yu had drawn before, nodded, and said: "walking in the cave, the consumption of grenades will be much less. If your calculation is correct, then the number of grenades we have now is indeed almost the same."Xiong Yu and sun LAN took all the grenades they found on their bodies and returned to the granite depression. They called out Wang Yunxiu and Leng Bingyan and asked them to follow.

In addition, sun Lan also untied the acupoints on Leng Bingyan's legs and hands, enabling her to recover her walking ability, but she did not untie the acupoints on the meridians that sealed the internal skill.

According to his own calculation, Xiong Yu and sun LAN began to open the cave with their hands and grenades.

I don't know how long after that, Xiong Yu and sun LAN finally got through the 400 meter distance in the cave. Wang Yunxiu and Leng Bingyan have been following.

Xiong Yu and sun LAN spent a lot of physical strength. After the 400 meter walk in the cave, they drank some water and ate some food, and then began the last 100 meter journey.

The last 100 meters are real stone walls. You need to use grenades to blast out a passage!

They used more than 30 grenades when they were walking 400 meters in the cave. However, during the journey, they found seven or eight Vanden family members who were killed and collected more than 40 grenades. Therefore, they still have more than 100 grenades on them.

Xiong Yu did not hesitate. After a short rest, he began to use grenades to open the road on the stone wall.

However, about two hours later, Xiong Yu stopped. He had already used more than 60 grenades and had blasted a cave about 100 meters in the stone wall. However, he did not find the underground river!

According to the previous calculation, the underground river should be 500 meters away from them. However, now that the distance has reached, there is no underground river, and there are still thick stone walls in front of them.

"What's wrong?" Sun LAN asked suspiciously

Xiong Yu frowned and said faintly, "I seem to have something wrong?"

Sun LAN under a set, quickly asked: "what is wrong?"

Xiong Yu thought for a moment and said, "what I calculated is the distance of a straight line. The cave is curved, and the cave we blast out is not straight, so the underground river should still be ahead."

Sun Lan said in a hurry: "then continue to explode, we still have 80 grenades."

Xiong Yu said with some worry: "if all the bombs are used up and we can't get to the underground river, it will be troublesome."

Sun LAN is silent. Now the food and water are almost exhausted. If there is no grenade and no underground river, it will be really troublesome.

Xiong Yu squinted and said, "blast it first. I think it can blow through. The bending distance of the cave should not exceed 200 meters. We can blow it through."

After Xiong Yu finished, he continued to place the bomb and detonated it carefully.

This time, it took about three hours. With only seven bombs left, they finally found the hidden River in the mountain from the mountains!

When Xiong Yu saw the broad underground river, he was deeply relieved.

Sun LAN exclaimed excitedly: "it's exploded at last!"

Xiong Yu said to himself: "fortunately, when I came, I brought mice and gold thread. Otherwise, I would be trapped here."

Sun LAN took a deep breath and calmed himself down. He asked, "how can I swim out of the river?"
