In the evening, Wu Song returned to his residence and found that the spirit rhino cub had not returned, so he felt that something was wrong.

He was worried that the spirit rhino beast had escaped from the fortress, and there was blazing magma everywhere outside, as well as magma monsters and snakes and other monsters. Although the Spirit Rhino Cub Beast is a seventh-order demon beast, it is young after all, and its strength has not yet grown up.

Wu Song was afraid that it would encounter some accidents.

The wolf said, "Otherwise, let's all go and find out, don't really have an accident." ”

Wu Song said, "I'll go look for it, this is a fortress after all, a few of us are investigating around, it's not too good after all, you just stay here." ”

Wu Song came to the kitchen first, and after running for a day, the spirit rhino young beast should also be hungry, maybe it ran to the kitchen to find something to eat.

The kitchen was not found, so Wu Song searched from east to west.

Mu Ling came out of the room, saw Wu Song, and after asking the reason, he also began to look for it.

The two quickly searched the courtyard of the fort and found no spirit rhino cubs.

Mu Ling came forward again and took Wu Song to the soldiers' barracks, conference hall, armory and other places, and the two of them found it until it was dark, but they still didn't find it.

There were still a few places in the fortress that they hadn't found, but they were all classified places, and no one could enter them without Musa's permission.

Wu Song felt that it was a bit of a fuss to go to see Musa in order to find the spirit rhino beast, so he gave up looking for those places.

Wu Song returned to his residence, but the spirit rhino cub did not return.

Wu Song's heart was a little uneasy, and now it was almost certain that something must have happened to the spirit rhino cub.

Wu Song didn't sleep all night, thinking about how to find the spirit rhino cub.

If he and the Spirit Rhino Demon Beast had already recognized the Lord before, then there would be a wireless connection between the two sides, and Wu Song would be able to find the Spirit Rhino Demon Beast based on this wireless connection.

However, Wu Song believed that recognizing the Lord was depriving the spirit rhino cub of its freedom, so the ceremony of recognizing the Lord was not carried out.

Therefore, now Wu Song is helpless, except to wait for the spirit rhino young beast to come back by itself, he has no other way, he can't help but regret a little that he didn't carry out the ceremony of recognizing the master.

In the morning, Mu Ling came to inquire about the situation of the spirit rhino cub, and after learning that he had not yet returned, Mu Ling said, "There is a kind of demon beast raised in the fortress, with an extremely sensitive nose, and it can smell the smell of sorrow more than ten miles away.

Perhaps, we can use this demon beast to find the spirit rhino cub. ”

Wu Song was overjoyed and said, "You can give it a try." ”

That kind of demon beast is called the Eye Beast, and it is very small, about the same size as the common cats in Dongzhou.

Mu Ling brought over a side beast, and Wu Song let it smell Yunrong's clothes.

Previously in Flying Eagle City, Wu Song tied the silk scarf that Yun Rong gave him to the neck of the spirit rhino young beast, and the spirit rhino young beast found Yun Rong accordingly.

Later, the silk scarf was always worn around the neck of the young spirit rhino beast and never taken off.

There is the breath of Yunrong on the silk scarf, and after the beast smells the breath of Yunrong, you can find the spirit rhino baby beast accordingly.

The eye-side beast set off, it left the residence of Wu Song and the others, sniffed all the way on the ground, and came to the root of the western wall.

Then, the beast stopped there, screaming at a pile of debris in the corner.

It was a remote place, and people from the fort rarely passed through it. I don't know when the pile of miscellaneous items was piled up there, and it was already dilapidated under the wind and sun.

Mu Ling grabbed the eye-eyed beast and said, "There should be clues in the sundries." ”

Wu Song brushed aside the debris and saw that there was a hole in the corner of the wall. Judging by the size of the cave and the freshness of the soil at the entrance of the cave, it should have been dug up by the spirit rhino cub not long ago.

Wu Song squatted down and put his head next to the entrance of the cave.

There was a breeze blowing from the cave, and Wu Song faintly heard a dense sound.

It sounded like an army the size of an ant marching. However, Wu Song knew that this was simply impossible.

Wu Song shouted at the entrance of the cave, hoping that the spirit rhino young beast could come out after hearing it.

But after waiting for a long time, there was no response from the cave.

Wu Song looked at Mu Ling and said, "Can you dig a bigger hole?"

Mu Ling said, "After all, this is a city wall, and it is a matter of city defense, so I can't be the master." You wait here, and I'll go and ask the Musa chief. ”

About an hour later, a group of people hurried over. Patriarch Musa walked in the front, and before he could get to the front, he couldn't wait to say, "Where is that hole?"

Mu Ling led the Musa Patriarch to the cave, and the Musa Patriarch looked a little solemn, and said to his subordinates, "Dig the hole immediately, I want to see what is underneath." ”

Wu Song was a little puzzled as to why Patriarch Musa reacted so violently, and said, "Patriarch, is something happening?"

Patriarch Musa frowned and said, "Just now, the lookout soldiers on the city wall reported that there was an anomaly in the magma.

I reckon that this time the beast will wake up early. Every time he woke up, there was a detailed record in the fortress. For hundreds of years, there has never been a deviation, and it is only at the time of sixty Jiazi that the beast will wake up.

But this time things went wrong, I don't know why, but I had a hunch that this attack would be more violent than before.

So, I allow for a slight lapse in the city's defenses.

The timing of this hole is so coincidental that I really don't feel at ease. ”

Soon, a group of soldiers dug the hole two feet deep.

At first, the hole was very narrow, but after digging two feet, the hole became extremely wide. In fact, what they saw was a large hole more than a meter wide.

The hole stretched all the way out of the walls, and it looked like it was going through under the walls.

The hole was covered with claw marks, which seemed to have been excavated by a group of demon beasts.

Seeing this hole, Musa's expression became very grim. Mu Ling's face showed a look of disbelief, although Wu Song didn't understand military affairs, he could also see how dangerous this hole was for the city defense.

If the thorn poured in from this hole, the fortress would never be able to hold it.

Musa immediately turned around and instructed his men, "Gather men at once and plug this hole." ”

Wu Song hurriedly said, "Patriarch Musa, my spirit beast is still in the cave, I want to go down to the cave and find my spirit beast." ”

Musa said, "The military situation is urgent, we will wait for half an hour, if you don't come back within half an hour, then we will block the hole in the ground." When the time comes, you may die outside. ”

Wu Song said, "Half an hour is enough, if I don't come back by then, you can follow your own plan." ”

After Wu Song finished speaking, he jumped into the hole.

The hole in the ground was a little narrow, and Wu Song couldn't stand, so he could only move forward on all fours.

After walking for a while, Wu Song suddenly realized a problem. Earlier, Mu Ling told Wu Song that most of the Demon Beasts were three to five meters in size, and if that was the case, they would not be able to pass through this cave.

That is to say, this cave is not for the demon beasts to sneak attack the fortress, so what is this cave used for?

A quarter of an hour later, Wu Song crawled out of the land for five or six miles. Not far ahead, a bright light appeared. It was an exit to the ground, and Wu Song climbed out of the exit and stood on the ground.

He looked around and found himself standing next to a volcano. The tall walls of the Guardian Fortress were miles away, and the soldiers on the walls were busy walking around.

There were stray footprints on the ground, and it looked like they were left by a group of monsters. The footprints led in one direction, and Wu Song followed the footprints.

He walked through a clearing and came to a valley.

At the end of the valley is a volcano with billowing smoke. There are a lot of monsters walking around in the valley, and they look like vines and monsters at the same time.

They all have long, slender vine-like bodies with branches and leaves growing on them. However, in both places at the head and tail, there are two claws.

In particular, the two claws on the head are very sharp, like two large scythes.

This monster is called Motogimon, and what it is best at is digging. The two sickle-like claws on their heads can easily shatter hard rock.

The cave that Wu Song discovered before was their masterpiece.

This wood beast is also the same as the magma monster snake, but it obeys the orders of the demon beast.

At this moment, the Honmu Beast is busy in the valley. Part of the Honwoodmon was digging on the ground of the valley, and part of it was on the volcano at the end of the valley.

The Honmumon in the valley is digging a trench in the ground, which is connected to the volcano at one end and spreads towards the mouth of the valley at the other.

Wu Song looked at this ditch, and then looked at the topography of the valley mouth, and his heart moved.

The terrain of the valley mouth is low, and the ditch must have been used to drain something, and the topography of the valley mouth just formed a natural ditch.

And beyond the valley mouth, it is the hole that Wu Song came out of before.

The ditches, valley mouths, and burrows formed a long ditch with a volcano at one end and a fortress at the other.

Wu Song looked at the Honmu Beasts on the volcano, they were obviously digging for something. Some of the Timberbeasts were digging, while others were carrying the excavated rocks to the side.

Wu Song quickly understood what they were doing, they were digging on the side of the volcano. These monsters want to dig up the volcano, let the lava flow out, and drown the Guardian's fortress!

These cunning demon beasts, I didn't expect their plans to be like this.

Wu Song had to stop them, otherwise by the time the magma flowed into the fortress, all the people inside would be finished. Yun Rong, the general wolf, the city lord of Flying Eagle City, etc., all of them will either die from the magma or die from the subsequent attack of the Devil.

But the number of those Native Wood Beasts was too much, and Wu Song alone couldn't deal with them.

Wu Song looked at the valley and suddenly his eyes lit up. At Taniguchi's place, he found a huge rock. The rock stood at the mouth of the valley and did not come into contact with the rocks next to it.

The rock must have been inadvertently left behind by the Honmu Beast when it was digging through the mountain at the mouth of the valley.

The mountain rock is seven meters high, and if Wu Song can knock it down, then the mountain rock will block the mouth of the valley, so that when those Honmu beasts dig up the volcano, even if the magma flows out, it will be blocked at the mouth of the valley.
