Xia Jin doesn't doubt that there is him. She immediately leaves with the housekeeper and goes to the backyard.

Like the last time, Xiao Yiyuan still lives in Nanyuan.

The housekeeper takes Xia Jin out of Xiao Yiyuan's room and retreats. Xia Jin steps forward, taps on the door two times, and then pushes the door in.

Inside, Xiao Yiyuan was standing at the round table, looking down at the battle map on the table.

At present, the situation is extremely unfavorable to Dongqing. Xiao Yiyuan frowned and felt heavy, thinking about the countermeasures.

Xia Jin steps in front of her body. He doesn't look up, but he takes her by the waist with great accuracy, takes her to his arms and buries his head in her neck.

Sniffing her unique pleasant smell, Xiao Yiyuan's solemn and depressing mood was relieved.

"Jin'er, at present, the north, South and west sides of Shicheng are besieged by the army of Beiyou. Wanyan Feihong has 300000 troops, Ximen has 150000 troops, and the other two gates have 75000 troops each. And the enemy commanders of each gate are good at blocking hundreds of enemies. Do you see... Can they have a solution?"

Xiao Yiyuan stretched out his hand and pointed to the map.

"We have used this empty city plan last time. Wanyan Feihong will not be fooled. To keep the stone city, the most important thing is to keep a line of sky, but now the line of sky has been broken, and the army of Beiyou is facing the city. If the stone city wall is not tall, and it is built with stones, it can resist the attack of Beiyou explosives to a certain extent, I'm afraid the city will no longer be protected! If we want to retreat, the only way is to suppress the enemy's absolute strength and fight hand in hand, so that they will not dare to fight any more! "

On the way here, Xia Jin has been thinking constantly, but she has no other way to get rid of hard work.

"So, jin'er is consistent with what I think."

Xiao Yiyuan's tone is a little self mocking helplessness.

Feeling his depression, Xia Jin embraces him and looks up at his handsome face

"Xiao Yiyuan, if you pay attention to strategy and put in the right formation, you can do the most damage to the enemy with the least loss!"

"I don't know what you said, but now there are a large number of explosive packs in Beiyou army. Any formation can't exert its power under such weapons."

This is the problem that bothered him most during this period of time, and Qin Yu could not solve it.

"Then use the three bow crossbow to aim at the possible location of the enemy's explosive package, launch a rocket and detonate it!"

Xia Jin quickly took over the conversation, and her tone was firm.

In the battle of Huazhou City a few days ago, if she had not discovered the magical function of lizijiang outside Huazhou City, she would have summoned the skilled craftsmen in the city to make three bows and crossbows. When Ji Ru was unprepared, she would have fired rockets northward from the camp in order to detonate the explosives in his camp.

Unexpectedly, the backup strategy of the first World War in Huazhou City was finally used in Shicheng, which was nearly thousands of miles away.

Smell speech, Xiao Yiyuan eyebrows move, look at Xia Jin's eyes with a little incredible.

After thinking for a moment, he heavily kisses Xia Jin on the forehead, fondly touches the top of her hair, opens his mouth, and his low voice is full of praise and love

"It's worthy of being the woman I like. This brain is the light of inspiration!"

With the range of the three bow bed crossbow, he only had to order the soldiers to transport the three bow bed crossbow out of the east gate, make a detour from the north to the peak of Qifeng mountain in the north, and shoot the arrow from the peak of Qifeng mountain. The Xichuan enemy camp outside the West gate was within its range.

At that time, as long as one of the explosives is successfully detonated, there will be a collateral effect

If the situation is better, he can even take the opportunity to open the city gate and lead the soldiers to kill the generals, so as to catch the enemy in Beiyou unprepared.

How could he not have thought of such a clever method?

But

"Jin'er, you and the drawing of the three bows, bed and crossbow, I'll ask people to gather craftsmen and open up the road to Qifeng mountain."

At present, there are only three bed crossbows with three bows in Shicheng. If we want to hit the place where the explosive bag is, the probability is very small.

Qifeng mountain is steep, and most of the mountains are cliffs, so it is very difficult for ordinary people to pass.

This is also the reason why the army of Beiyou didn't make a detour to dongchengmen and besieged Shicheng on all sides.

However, even so, Xiao Yiyuan also had a way to transport the three bows to the top of the mountain.

However, before that, he has to do his best to remove more obstacles.

If you want to do it, you have to do it to the extreme!

"Well, you can go quickly."

Xia Jin knew that the situation was urgent, so she could not help them delay too much. She nodded her head and urged her at the same time.

Xiao Yiyuan scratched her nose and once again put a little water on her forehead. Then he released her, turned and strode out of the room.

Xia Jin collected the battle map, unfolded a blank piece of rice paper, took a brush, broke it, and began to draw on the paper with the hard end.

One by one, from the overall rendering to the detailed data of each part

……

When Xiao Yiyuan arranged to come back, Xia Jin had not finished drawing.

He waited quietly. After about a stick of incense, Xia Jin finally finished drawing the detailed data map of the last part. She put aside half of her brush and gently blew the ink on the rice paper to speed up its drying up.

Xiao Yiyuan looked at her and saw that her cheeks were flushed with fatigue. At the same time, she felt distressed. She wanted to take a big bite on her attractive cheek like an apple.

In the end, however, he chose forbearance.

In the present situation, he has no time to do anything else.

After the ink dried up, Xia Jin folded all the rice paper that had drawn the pattern data of the three bow bed crossbow, and solemnly handed it to Xiao Yiyuan.

"If you put it away, you must tell the craftsmen that there should be no deviation, otherwise the final assembly will fail!"

"Well, you can take a rest here. If you want to see Qin Fengmu, let the housekeeper show you the way, otherwise you can't get in..."

"I'm not a three-year-old. You don't have to tell me that. Go quickly."

See Xiao Yiyuan unexpectedly so exhort, Xia Jin stretched out her hand to push toward the direction of the room door.

Xiao Yiyuan took her hand and scratched it badly

"Jin'er, I miss your taste."

With such an ambiguous and charming remark, Xiao Yiyuan immediately turned and left.

In the room, Xia Jin knows later that she is killed by Xiao Yiyuan again

This old fox is really more and more difficult to deal with.

She reached out and patted her cheek, which was slightly warmer. She let out a long breath. After the rhythm of her heart returned to normal, she opened the door and went out.

Just to see two maidservants in the hospital busy, Xia Jin asked the housekeeper at this time may be where, quickly find.

……

Nanyuan was originally Qin Fengmu's residence. At this time, he also lived here. However, because he was seriously injured, he is now comparable to being disabled. The news must be kept strictly confidential. Therefore, he did not live in the dormitory where he used to live. Instead, he changed a room, and only a few people can enter.
