Yu Wenxuan raised his eyebrows and said with a smile, "Then what's the matter, go out of the city now?" ”

"Don't worry, let's see what the Bohai Navy does first." Tian Shaotu put his arms around the shoulders of the two friends and pulled them down the city wall.

"Naughty ......" Yu Wenxuan deliberately suppressed his throat, stretched out his index finger and tapped it on Tian Shao's chest, and quipped.

"Hey......" Zhang Shaohua and Tian Shaotu expressed their dislike for Yu Wenxuan with very disdainful eyes at the same time.

That night, the guards reported that torches had flashed in the naval camps in four directions outside Bocheng, and they suspected that they were going to send troops to attack the city. The generals of the Black Feather Army then rushed to their respective positions. Yu Wenxuan and the other three came to the east gate, the city was already full of the Bohai Navy, and from the light of the torches, they could faintly see the siege equipment such as crashing wood, ladders, and catapults.

Although spring has begun, the evening breeze blows, still with a little coolness, blowing away everyone's deep sleep. Yu Wenxuan walked straight to the edge of the city wall with the Bixiao Sword on his shoulder and looked down.

"Young apprentice, why don't Haoxuan and I follow the method you said during the day and lead the troops down to kill a circle?" Zhang Shaohua glanced at Yu Wenxuan, and then asked Tian Shaofu.

"It's still late, and we don't know if there are still enemy soldiers hiding in the darkness outside, so it's not appropriate to go out of the city for the time being." Tian Shaotu frowned slightly, shook his head and said, "It's better to stay and defend the city, and make a decision according to the situation." ”

However, it was said that outside the city, Shi Guangtong sat on the back of the green beast, raised Fang Tian's halberd and pointed directly at the city tower, shouting and ordering, "Kill!" With an order, I saw countless bows and arrows shooting from behind Shi Guangtong in an instant, and the Black Feather Army hurriedly raised their shields to block it. But after a wave of bows and arrows was fired, not a single Bohai Navy soldier came out of the battle.

The rain of arrows ended, followed by the sound of drums, but the momentum was still huge, but the enemy still did not come out. Shi Guangtong led the troops to toss under Youzhou City for a full hour before leaving.

"Report to the prince, the marshal, the military division. The enemy forces at the west gate withdrew. ”

"Newspaper - the enemy forces at the north gate have retreated."

"Those at the south gate have also withdrawn."

As soon as the Bohai Navy left, three soldiers came to the east gate city wall to report to Yu Wenxuan and others.

"Is Shi Guangtong also planning to make a plan to exhaust the enemy?" Seeing the orderly withdrawal of the enemy troops under the city like a receding tide, Tian Shaotu couldn't help but smile after thinking for a while, "This is to return the favor to the other in the other way." ”

"Then it's up to him to learn a few points." Yu Wenxuan said, and immediately ordered, "Pass the order, let the brothers be on duty in shifts, change every other hour, be sure to pay close attention to the movements of the Bohai Navy, and not be negligent." ”

"No!" The herald beside Yu Wenxuan arched his hand.

Yu Wenxuan frowned and thought about it, then suddenly turned around and said, "Young apprentice, how long did you say that our grain and grass can last today?" ”

"A month." Tian Shaotu replied.

"Shi Guangtong...... I'm afraid it's not just a tired tactic. Yu Wenxuan's face suddenly became a little flustered, "The Bohai Navy scouts must have found out that there is not much grain and grass in Youzhou City, so I am worried that Shi Guangtong will not attack because it is to waste time with us." He took a deep breath and continued, "The Bohai Navy is besieging the city, not to mention the grain transport troops, even the messengers are difficult to break through. Maybe Shi Guangtong wants to consume our grain and grass while draining the will of our army. When our army is physically and mentally exhausted, we will attack again. ”

"If that's the case, it's terrible." Zhang Shaohua looked at the camp of the Bohai Navy from afar and muttered.
