After drilling out from the hidden exit, Rob took out the Blood Spirit Bead and summoned it gently. After half an hour, a blue shadow shot vertically from the sky above the clouds, flew to Rob's head before spreading her wings and hovering.

Durodo, who hadn't seen for a long time, became bigger and smoother, and very clear blue. As a flying monster, Durodo couldn't live underground for a long time, so after Rob moved his home underground, Durodo returned to the giant wood forest.

"What's the matter with me?" Maybe I haven't seen each other for a long time, Durodo's expression showed a sense of intimacy. He arched Rob with his head and asked.

Rob said the possible invasion of the savages in Black Iron City, and said, "Supervise them from the air." As he said, Rob took out a necklace from the ring and put it around Dourodo's neck.

The necklace is made of leather and is woven from several tough monster skins. Every distance, there are four bone rods in total. Durodo is a spiritual monster and is the most sensitive to the soul. It clearly senses strong soul fluctuations in the bone rods.

As long as it wasn't an explosive steel belt, Rob let the necklace be put around his neck. Dourodo asked curiously: "What is this?"

Rob explained that the soul strung with the necklace had a deep connection with him, and he could transfer his mind to these souls at any time, so that he could sense the situation where Durodo was located. The reason why four souls were used was that after being tied to Durodo's neck, there would be no dead corners to perceive.

"I'm just monitoring the situation of the barbarians from the air, right? No problem." Dourodo responded excitedly, flapped his wings and soared into the sky, and quickly disappeared above the clouds. But he was monitoring the situation from the air, and there was no danger at all. Dourodo naturally would not refuse, especially since he had never experienced a large-scale war, but was still a little excited.

...

Two days later, in a house near the inner city river in Black Iron City, Rob pushed a small gap into a window on the second floor and looked at a group of soldiers running quickly from the road by the river. Each soldier was fully armed, holding a spear.

A soldier in the lead held a magic megaphone and ran and said loudly: "Martial law has begun in the city. Please do not leave your home at will, do not stay on the road, and do not spy on any military facilities. Otherwise, we will be punished for espionage. Our city defense force has been mobilized and has absolute strength to protect the safety of the Black Iron City. Please rest assured by all citizens."

The soldiers in the lead repeated over and over again, shouting that they would change people when they were tired. They had time to stay or watch along the way, and they directly drove away the tail of the spear. Not long after, there was no one on the whole road.

There are dozens of such teams in Black Iron City.

In the city walls and in the city, all the towering magic towers began to illuminate the light of energy. The waves of magic began to spread from the magic tower, sweeping across the city from time to time. The entire city's ground and underground were monitored by these fluctuations.

Black Iron City is a well-connected city with countless channels underground to lead outside the city. During the war, in order to prevent the enemy from entering the city from underground, monitoring of each channel is the top priority. As long as you sense the movement of the enemy, the ground magician who has been waiting for a long time will launch it and bury the enemy underground forever.

Therefore, if we had not fully grasped the advantages of war, no one would dare to attack the city from the ground.

Rob also considered this and entered Black Iron City two days in advance. The house they are now in is one of the secret industries purchased by the Iron Shield Mercenary Group.

No matter how small the power is, it is very important to be prepared for danger in times of peace. Tieler has started to deal with many real estate in Hei Tiecheng for a long time, one for investment and value-added, and the other for the purpose of allowing you to have a place to settle after an unexpected situation. Such an arrangement may never be used, but it may be life-saving when used.

After watching the soldiers disappear at the end of the street, Rob closed the window, closed his eyes, and rushed to the distance, and soon moved to a soul on Dourodo's neck.

The entire earth is covered with black tides, and the 'tides' are barbarians, countless barbarians, including cats, rats, bear goblins, ogres, and taurens. There are also species that are strange in shape and cannot even name them.

These wilderness barbarians were scattered on the periphery, chaotic and rushing across the earth like a tide. In the center of these crowds, there was a relatively dense formation. All the creatures that formed this formation were tall and strong humanoid creatures. They were naked and their muscles were high and bulging, hard and strong, like rocks.

He has thick body hair, and his front jaw is protruding high, pushing up his thick lips, and four sharp fangs are exposed, looking like a mutational ape. This is the alpine barbarian living on the snow plateau north of the Hengduan Mountains.

Although the formation they formed was not very neat, they could clearly see a certain order and clearly organized, many times better than the barbarians of the wilderness like a scattered sandy wilderness outside.

They rushed through the earth like a tide. All the human villages and towns outside of them turned into ruins, and rolling black smoke rose into the sky.

These barbarians appeared in the wasteland a day ago, like a tide pouring in, submerging the Dali Oasis, the largest stronghold of humans in the northwest wilderness. None of the 800 humans in the entire oasis could escape.

Then, the barbarians advanced all the way without stopping, and reached here in one day, only three days away from Black Iron City.

From the moment the army of barbarians appeared in Dali Oasis, Black Iron City received an alarm, and continuously reconnaissance griffins were sent out to reconnaissance the intelligence and movements of the barbarians. Durodo had encountered several waves of human reconnaissance griffins, but Durodo's flight altitude was many times higher than that of griffins. It could detect the other party, but the other party could not detect its existence at all.

In fact, even if you notice it, as long as it doesn't attack it on its own initiative, the human griffin scouts will not mainly provoke it. After all, Blue Feather Ling is a level nine flight magic. Even if she is not an adult, it is not comparable to these level four or five griffin.

After obtaining accurate information, the Black Iron City entered a state of war. The city was martial law, underground surveillance, and defense cover were ready to be opened at any time because the enemy was a barbarian. For a time, all the barbarians in the Black Iron City were included in the control targets, and the barbarians who appeared in the city were captured and imprisoned to prevent riots during the war.
