Zhao Xuan and Hei Yun quietly passed through the highway at night and used various terrains to reach a place about a kilometer away from the inner city wall.
After hiding his figure, he picked up the infrared night vision telescope and began to observe the city wall ahead.
He had to be so careful. At this distance, his infrared equipment could see the defenses on the city wall, and his movements could also be seen on the city wall.
"Tsk tsk, the defense is really tight enough."
Zhao Xuan looked at the densely packed red figures on the city wall and curled his lips.
He was now acting alone with Heiyun, without teammates to drag him down. No matter how tight the opponent's defense was, it was nothing more than that in his eyes.
"Heiyun, go over there..." Zhao Xuan confessed in a low voice.
After hearing this, Heiyun immediately stood up and ran towards the right front.
Its figure was immediately exposed to the infrared telescopes of the defenders on the city wall.
"There's something over there!"
Several defenders who discovered the black cloud shouted, and in unison they turned on the searchlights around them and shined towards the black cloud.
Almost all the defenders on this wall turned their attention to Hei Yun.
'Da da da......'
Countless heavy machine guns immediately fired fiercely at the black cloud.
But the black cloud is so fast that almost no bullet can hit it. Even if there was an occasional hit, it would only cause Heiyun's body-protecting golden light to tremble slightly.
Gunshots rang out, and the closely guarded team of spirit warriors in the city, led by Shan Shifeng, Shan Shiying and Ke Peiquan, quickly ran up the city wall, preparing to sniper the night attackers.
But this all takes at least 1 minute.
"You shouldn't notice me now."
Zhao Xuan snorted, immediately activated his body shape, and rushed towards the city wall from the left, almost touching the ground.
As Zhao Xuan expected, almost all the defenders on the city wall were paying attention to the black clouds shrouded by a few searchlights, and did not pay more attention to other places. In addition, Zhao Xuan is infinitely close to the ground, making it even harder to detect. This allowed Zhao Xuan to easily get close to the base of the city wall.
Zhao Xuan pressed his hands and feet against the city wall and quickly climbed to the top of the city wall.
When he was about to emerge, Zhao Xuan carefully sensed the positions of the dozen soldiers above his head.
With a thought in his mind, he activated teleportation.
The next moment, his figure appeared inside the passage on the city wall.
At this time, in front of Zhao Xuan, the dozen soldiers were looking at the black clouds attentively, and no one noticed that there was an extra person behind them.
Zhao Xuan smiled slightly. The first step of the plan was successful!
He immediately started walking around on the city wall as if nothing had happened.
Soon he selected a suitable place. While no one was paying attention to him, he teleported again and came to the ground in the inner city.
When Zhao Xuan landed, Shan Shifeng had already led a group of spiritual warriors up to the city wall, watching eagerly at the big black dogs rushing left and right under the city wall, looking for gaps in the attack.
Through the brief encounter during the day, Shan Shifeng already knew that the big black dog was level six. But he was undaunted.
He believed that he and others could definitely stop the big black dog. And if the big black dog didn't retreat midway, he might even have the chance to win the big black dog.
The black cloud danced under the city wall for a moment. Under the impact of the bullets and the interception of the spiritual warriors, it was still unable to rush up to the city wall, so it had to roar loudly, turn around and leave.
"Brother, what do you mean by this?" Shan Shiying pointed at the back of the big black dog that was walking away quickly and said doubtfully.
"What do you mean? It's nothing more than testing our guard situation. This big black dog is level six. If it can successfully rush in, it will definitely disturb the inner city and may cause heavy casualties to us. Only Unfortunately, under our tight defense, it has no chance of success." Shan Shifeng said with a sneer.
"Brother, is it possible that they are attacking in the east?" Shan Shiying said a little uneasily.
"Are you saying that this big black dog attracts our attention and provides cover for others to sneak in? This possibility is possible, but the chance is very small. After all, our soldiers monitor closely, and there is no interaction between people. The distance between them is still so close. Even if someone from another place wants to sneak in, how can he avoid the sight of our soldiers?" Shan Shifeng hesitated and said.
"Yes." Shan Shiying nodded.
What the two brothers didn't know was that Zhao Xuan had successfully broken through the 'human wall' on the base's city wall using his 'teleport' skill, and was currently roaming freely in the inner city.
Of course, that may be a bit of an exaggeration. Although Zhao Xuan is not worried about anyone using infrared night vision equipment to find him now, and he is moving very fast, he is still cautious on the whole and takes every step carefully.
He took advantage of the other party's carelessness to sneak in tonight. If he accidentally lets the other party discover him and arouses his alertness, his mission tonight will fail, and it may not be so easy to sneak in next time.
The direction Zhao Xuan is heading is the direction where the artillery shells hit during the day. He wanted to follow this direction to find the artillery position at Lanjing Base, and then destroy all the cannons.
Only by destroying the opponent's cannon can his next move go smoothly. After all, it is a bit more difficult to fight against strong opponents under heavy artillery bombardment.
Along the way, Zhao Xuan mainly looked for places with lights.
He would look carefully at every place where there was a light.
Soon, after Zhao Xuan advanced four kilometers, he found an artillery position as he wished.
It was less than an hour before he sneaked into the city.
"Thank you! Thank you very much that they did not implement blackout." Zhao Xuan was extremely happy for a moment.
Because the artillery position is located deep in the base, the soldiers here generally do not have much sense of crisis, and the patrols are not strict at all.
For super master Zhao Xuan, it is not easy for him to deal with these ordinary soldiers who are mainly strong fighters.
He easily found an opening and sneaked into a barracks.
After knocking out all the soldiers in the barracks, Zhao Xuan took a soldier hostage out of the barracks and entered a small forest.
He woke the soldier and put his dagger to the soldier's throat.
"If you want to survive, tell me honestly how many artillery positions there are in the base and where they are?" Zhao Xuan asked in a low voice.
"There are three artillery positions, each at..." the soldier replied quickly.
Within 10 minutes, Zhao Xuan interrogated three soldiers and obtained accurate information.
There are indeed three artillery positions in the base, each with 400 heavy guns.
Zhao Xuan immediately started busy from this position.
He took advantage of the gap when the patrolmen walked by and quietly destroyed the aiming scale on the cannon.
When the sky was about to break, Zhao Xuan finished what he wanted to do.
