Everyone looked towards the place where Hua Zi was pointing, and the water near the shore tumbled, as if something had floated up.

Liang Gang asked the two guards to go over and take a look at it at once, and provoked it with their spears to see what it was.

The two guards slowly approached the shore, walking very carefully, as if they were afraid that the monsters in the water would suddenly rise up and attack them.

They stretched their spears far away at something that came out of the shore, and then the spear seemed to pick something, and the two of them quickly looked over, and through the small glowing rods on the spear, they saw two human skulls, and they collapsed to the ground in fright.

Ma and Wu Tong walked over, took the spears in the hands of the two guards, and lifted the skulls of the two human bodies to the shore.

The jade girl and a few maids walked over with small glowing sticks in their hands, squatted down, and shone on the skull on the shore.

The flesh on the skull has been eaten by the piranhas, and there is only a gray-white skull skeleton left, which looks particularly gloomy.

The jade girl said: "These two skulls should be the two guards who fell into the river just now!" ”

After the jade girl finished speaking, all the guards were scared.

Liang Gang walked over, looked at it, and then nodded, "Everyone should be careful in the future, there are not only man-eating fish in this river, but also a lot of lava lizards." ”

Then, his guards retreated, pushing to a safe area where there were no piranhas.

The piranhas in the waters of the large underground river behind have been cleaned up by the things just now, so it's safe here.

The lizard's skeleton and two skulls were also picked up with spears to a safe area, and then, Liang Gang asked Han Xuening and Wei Yunxuan what to do next?

Wei Yunxuan, Mr. Wen and others all began to think of a way.

However, in the face of such a large body of water in front of us, everyone did not think of a suitable way.

Bai Zijun and Ma also rushed back from the front, just now, the two of them deliberately went to the front of the place where the water flow is fast and the area is large, and then go ahead, the entire underground passage is almost flooded by the underground river. The width of the water flow has reached six or seven meters.

It is no longer possible to get around the shore, you have to make a small boat and go slowly to cross the underground river.

Bai Zijun said to everyone: "Just now, my brother and I went to the front to see, and the front is almost all water, and I don't know how deep it is. It was impossible to walk through, only to row through it by boat. ”

Han Xuening nodded and said, "Brother Zijun is right, in order to pass through this secret passage, you must use a boat. ”

Liang Gang called the guards who were waiting in the back and began to assemble the small wooden boat with the materials he had brought.

This time, he brought a total of more than 300 guards, so everyone divided the labor and assembled the ship quickly, and in half an hour, five small wooden boats had been assembled.

Liang Gang asked everyone to go over and take a look at the small wooden boat, and there were any suggestions for improvement.

The group returned, walked across the underground river, and came to the flat area of the cave.

There are five wooden boats that have been made, the big one is about three meters long, and the small one is about two meters long.

Everyone took a closer look at the hull of the ship, the outside is wrapped with a layer of iron, so that it will not leak, if the man-eating fish attacks the ship, it will not bite the iron, it is indeed well designed.

In addition, there are oars and pickaxes that have been assembled, and it seems that they have been designed in advance.

Everyone said it was a good design.

Han Xue thought for a while and said to Liang Gang: "Village master, I think that if you nail those sharp tooth pieces under the bed, if the strange fish or the lava lizard in the water come to attack the ship, you will be injured." Injured monsters bleed, and when they smell blood from the man-eating fish in the water, they will be devoured. ”

Han Xuening's method is very good, and everyone agrees.

So, Liang Gang just asked the guard craftsmen to start improving the ship according to Han Xuening's ideas.

Everyone was resting in the cave, and at this time, Hua Zi remembered that Mr. Wen had not answered their question just now.

"Mr. Wen! You didn't even say why those man-eating fish don't attack lava lizards in the water? ”

Mr. Wen smiled and said, "Lady Huazi, lava lizards have thick skin, even if you use a knife to cut their skin, they will not have any wounds on their bodies when they swim in underground rivers." The man-eating fish only attack their prey when they smell the blood in the water. Lava lizards don't get hurt and don't bleed themselves, so the man-eating fish won't attack them. ”

After Mr. Wen finished speaking, everyone realized that this was the case.

The group had rested in the cave for less than half an hour, and the guards had already improved all five boats.

The bottom of each ship has several rows of sharp teeth, and the bottom of the boat is under the river, and if the strange fish or lava lizard attack, it will definitely be injured, and when the time comes, those injured monsters will become the prey of the strange fish.

Liang Gang asked a few guards to slowly move the small boat that had been made into it, and moved it to a place with a wide current in front of him.

Small boats were lowered into the water of the underground river. The first small boat was more than two meters long, and Liang Gang had three guards stand on it, each holding a sharp spear in his hand.

The three guards got into the boat and began to paddle forward, the waters they were in had not been cleaned by piranhas, there were not only piranhas, but also lava lizards.

The three of them rowed a small boat to experiment, paddling the boat all the way forward, and they could also explore the length of the entire underground river.

Three guards were standing in the boat, one behind him was paddling with oars, and the two in front were holding sharp spears in their hands, constantly stabbing in the water.

Sometimes it will stab the man-eating fish in the water, and the injured monster fish will soon be eaten by the strange fish that are lying in ambush around it, and the smell of blood will come out of the water.

The boat slowly rowed forward, and the people on the shore were worried about whether there would be any accidents.

After the boat had been running for more than ten minutes, the people on the shore could no longer see them.

Huazi said: "The river is really long at the bottom, I don't know if there is any danger on the boat?" ”

Huazi was worried about the guards, and if they were attacked in the river, there would be no one around to come to their rescue, which was really dangerous.

Everyone waited on the shore for half an hour, but before the boat returned, everyone sweated for the three guards.

The jade girl said to Liang Gang: "The owner of the village! Will the guards who go to explore the path be in danger and trapped? Shall we send another ship over? ”

Liang Gang thought for a while and said, "Let's wait a little longer, maybe this underground river is very long." Wait until they get back. ”

Liang Gang still believes that there will not be much danger on the ship.

Han Xuening also said: "The owner of the village is right, let's wait." In another half an hour, if they don't come back, they may be in danger! ”

Half an hour passed in a blink of an eye, but there was still no movement on the surface of the underground river, and everyone was worried.
