Luo Zhaoyun drove the expedition in person, and arrived at the edge of Qishan with the Chinese army, seven or eight miles away from Qishan City.

"Take the Imperial Guards and follow me to patrol the terrain." Luo Zhaoyun had to personally observe the topography and formulate a battle plan.

Although Hou Junji sent someone to send a letter of request, he basically played a conventional way, fighting hard, relying on crossbow machines and urns to suppress the city, and breaking through layer by layer.

You must know that this mountain city has been re-strengthened, several trenches have been dug, and a wall has been built with stones to make an urn city.

As for gunpowder, although it works, if it is exposed too early, it will lose the effect of the surprise attack when it is really Gongke City later.

Moreover, it is still quite difficult to blow up the outer Guo urn city and attack it hard, because the Tang army defending the city deliberately dug a wide trench at the city gate, led the river in the mountain to flow through the outer Guoxia, and raised the suspension bridge, which made the siege more troublesome.

Unless there is a surprise army, answer from the inside, kill the defenders of the city, open the city gate, put down the drawbridge, and successfully kill the inside, you can take the outer Guo Weng City and threaten the inner city.

How do you get the soldiers in? Because Qishan City is not a prosperous city and is located in a remote area, the intelligence points inside are not large, and the manpower is not enough to plot against a large number of Tang army generals, or organize death squads to attack Waiguo.

"Your Majesty, beware of the Tang Army's rangers discovering and coming over to disturb!" There are scholars who admonish.

"Haha, when I am the weak emperor, don't forget, I went to the battlefield at the age of fourteen, a general on horseback, why not be afraid of the rangers!" Luo Zhaoyun didn't care, and took hundreds of guards out of the camp, like a mountain from the side, and then climbed high to look out to watch the direction of Qishan and the location of the mountain city.

The outer city Guo is close to the mountain, chooses to be between the two hills, crosses the stone wall, establishes the arrow tower and the battlement of the city, in order to worry about the enemy death squad, along the cliff by the rope to fall, so deliberately between the city wall and the cliff, separated by twenty or thirty meters away, with the rope can never jump into the city wall.

However, at that distance, you can glide smoothly over it!

There you have it, an easy glider!

Luo Zhaoyun smiled slightly, sent a special combat team, glided over, and jumped over the outer Guo of the mountain city, which would make the defense of the trenches, moats, suspension bridges, arrow towers, and several wooden barbed railings in front of the outer Guo completely useless.

This kind of glider flight has also been used several times in the daily training of the special combat team, but because it is rarely used in combat, it is not very practical, so it is discarded.

"Go back!" Luo Zhaoyun turned around and returned to the camp, and the imperial guards escorted him back to the camp.

On the same day, Luo Zhaoyun immediately called Yu Wenwen, the commander of the Shenji Battalion, he is Yu Wenkai's youngest son, Luo Zhaoyun and Yu Wenkai and Yang Su were responsible for the construction of Luoyang City, and they had a deep friendship, so when Yu Wenkai died in Liaodong, he sent someone to properly settle Yu Wenkai's family, and one of the two sons was taken to Zhuo County, and one was in the northwest.

Yuwen Wen clenched his fists and said, "What does Your Majesty command?" ”

Luo Zhaoyun picked up a sketch of a glider and said to Yuwen Wen: "Immediately let the Shenji Battalion secretly build this kind of glider, at least five hundred copies, each one can support the weight of two people when it is headwind, and glide from the cliff to the inner area of Wengcheng." ”

After Yu Wenwen took the sketch, he looked at the flying machine on it and nodded slightly, this kind of thing had been built for the special operations group in the northwest, and he had an impression, but this time it was slightly improved.

The glider is composed of four parts: the tower, the keel, the tripod, and the sling, and each part is connected by a steel cable. It is simple to structure, safe and easy to learn, as long as there is a hillside at the right height and six or seven steps against the wind, you can soar into the sky.

"Deadline, how long will it take to build?" Yu Wenwen asked.

Luo Zhaoyun said: "Supplies and materials need to be prepared, give you ten days, and rush to make them overnight." ”

"Yes!" Yu Wenwen turned and left.

Luo Zhaoyun sent someone to summon Ning Wufei, who was promoted to lieutenant when he was Tuyuhun with him in the northwest, and is now his henchman, and his eldest grandson Tong is in charge of the special forces corps.

"There is a new mission....... Luo Zhaoyun said the content and importance of this mission.

After hearing this, Ning Wufei and Eldest Sun Tong looked solemn, but they did not flinch, and they all agreed: "Please rest assured, Your Majesty, you will definitely complete the task." ”

"You will send 800 people, and there will be 200 special personnel to participate in the operation, each glider, two people to use, so that in the second half of the night, a thousand people can be thrown in to seize the city gate."

Ning Wufei and Changsun Tong left after receiving the order. In an instant, Qingshuang received a summons and entered the big tent.

Luo Zhaoyun asked her to select two hundred elites to participate in the action, Qingshuang listened, first fell silent, and then said, "I'll go personally." ”

"No, it's too dangerous, once exposed, it is likely to be surrounded and suppressed, and it is difficult to fly, I won't allow you to go!"

Qingshuang raised her head, stared at Luo Zhaoyun's face, felt the other party's tough tone and attitude, avoided her gaze, and said softly: "You know, only if I go, the success rate will be greater." ”

Luo Zhaoyun said in a firm tone: "Let you be so dangerous, I would rather not take Qishan City!" ”

"That's your hegemony, it's extremely important!" Qingshuang emphasized.

"You are even more priceless to me!" Luo Zhaoyun accentuated his tone, for Qingshuang, he had already regarded him as his own woman or concubine, but he had never held a ceremony and did not really share the bed.

Qingshuang's body trembled, stunned, and her heart seemed to be shaken, unable to calm down.

Although the relationship between the two has always been close to far, maintaining a special close friendship, like a confidante and a concubine, Qingshuang has never promised each other, that is, she feels that she is an assassin, the other party's status is getting higher and higher, and she is classified as a king, as long as she is by her side like this, it is good to be free, to be a concubine, but to be trapped in a cage and become a resentful woman, she would rather maintain such a respectful relationship.

But at this time, that sentence stirred up her original secret heart, throbbing and difficult to calm down.

"I don't want to be someone who loses value and doesn't help you."

Luo Zhaoyun leaned closer and said softly: "You've helped me enough, it's time to rest." ”

Qingshuang said quietly: "One day, you truly unify the world and give the people a peaceful and prosperous world, I will seal the sword again and release Manan Mountain." So, this time, you've got to let me go! ”

Luo Zhaoyun was moved by her dedication to her, hesitated for a moment, and smiled faintly: "This operation, it's okay to go, but you have to rely on me tonight." ”

"What do you want?" Qingshuang felt the other party's ill-intentioned smile, Fang's heart lost its calm, turned to the side of her delicate body, and pretended not to know.

Luo Zhaoyun walked to her side, took advantage of her inattention, made a decisive move, hugged her horizontally at once, and said with a smile: "Of course it's a waiter." ”
