In the past half a month, the Qin army has fought several times with the five-nation coalition army. Both sides won and lost each other, but they were never able to break through the opponent's defense.

In the Wei army camp, Xinling Jun Wei Wuji sat on top of the handsome case, his brows furrowed slightly.

The coalition forces and the Qin army clashed more than ten times, each time they were evenly matched. But this is far from enough for Xinlingjun. If there is no better chance to break the enemy and continue for a long time, then he can only choose to withdraw his troops.

Chu and Han have already retreated, and the other two countries may not have such thoughts.

If this stalemate continues, the three countries will withdraw their troops in half a year at most. At that time, only the Wei army will stick to this place, and it will be difficult to scream alone, and I am afraid that it will not last long.

"Gentlemen." After a moment of silence, Xinling Jun Wei Wuji slowly spoke: "Our army and the Qin army have been fighting here for three months, although the consumption of grain and grass can still be supported. However, if the situation continues like this, the situation is extremely unfavorable to our army, and Chu and Han have already retreated, and Yan has also shown signs of retreating. ”

"Will the plan be released?" Xin Lingjun looked at the generals under the tent, and his eyes swept over everyone's faces one by one.

"General, now that the Qin army and our coalition army are stalemate, neither of them can help each other, but at this moment, if you want to defeat the Qin army as soon as possible, you may only be able to make dangerous moves, bypass the Hexi front, detour back to Heluo, attack Luoyi, force it to come back to help, and force the Qin army to take the initiative to give up defense and fight to the death with our army!" Ji Yanran groaned.

The Yewang generation is an important town operated by the Qin State for many years, and it is not easy to bypass the garrisoned Qin army and go straight to the hinterland of Heluo.

"Newspaper—"

At this moment, the voice of the soldier suddenly came from outside the camp: "General Qiyu, the chivalrous leader asks to see." ”

"Ask him to enter the account."

"No!"

A moment later, a man dressed in cloth walked into the tent, and in addition to him, there was also a purple-haired woman hidden under the night clothes.

Because she is hidden in the night clothes, I can't tell her age, but from the figure, she should still be very young.

"Xinlingjun, it's her who really wants to see you." Although Xia Kui had doubts, he still chose to believe her and brought her to see Xinlingjun.

The purple-haired woman bowed to Xinlingjun on the throne without humility or arrogance, and said in a crisp and pleasant voice: "Xinlingjun, I came here this time to bring information to the coalition forces. ”

The purple-haired woman handed a copper shaft to Xin Lingjun.

"This is the Black Lotus Scroll, the Black Ice Platform and the things used by the military to transmit secret letters, it is rumored that it was developed by the Gong Loser for the Qin State, in addition to the Black Dragon Scroll and the Red Dragon Scroll that are more difficult to break and used exclusively by the Qin royal family to issue confidential documents. If you can't solve the method, force it open, or solve it incorrectly, it will trigger the mechanism and destroy the scroll. "Yang Gong's evil opinion is what this thing says.

Even if there is a secret hidden in this object, it is by no means easy to obtain.

"I don't know if you can see it with me." Fu Nian got up and asked.

"Naturally." Xinlingjun handed the Black Lotus scroll to Fu Nian.

Fu Nian took it and took a closer look. This scroll reminded him of the Da Vinci combination lock in his previous life, which was basically the same.

"This thing is quite mysterious, to open the scroll, you must unravel the twelve earthly branches corresponding to the scroll, there are six turntables on the scroll, each turntable has twelve earthly branches, which may be used as the permutations and combinations of ciphertext as many as 2,985,984 kinds, if you want to guess, even if you exhaustively, you can't open it without trial and error."

Fu Nian returned the Black Lotus Scroll to Xinlingjun, and briefly introduced the principle of the scroll to everyone.

He actually had a way to decrypt the password, but now it was too late.

"Is there any other way you can unlock this scroll?" Ji Yanran

Xiang Fu Nian asked.

He knew that Fu Nian would never do anything he was not sure of.

"I do have a plan to unravel it." Fu Nian said.

"How?" It was Yang Gongxie who spoke up, and he was very interested in what Fu Nian said.

Xia Kui set his eyes on Fu Nian, obviously, he was also interested in this method.

"The reason why you can't forcibly take out the scroll inside by external force is that it will trigger the mechanism and destroy it, and if you don't let the mechanism trigger, you can't easily take it out at that time." Fu Nian said.

"What you said is true?" The purple-haired woman's beautiful eyes flashed with brilliance and asked.

"I'm about 90% sure." Fu Nian said.

"Brother Fu, I know that you are a capable person." Zhang Tan patted Fu Nian's shoulder and praised.

"Just find a person who cultivates the Yin Exercises, and let them use their internal force to instantly freeze the scroll and create an environment with extremely low temperature, and then they can directly break the scroll and take out the secret book." Fu Nian said.

As far as he knew from his previous life, most acidic liquids had a freezing point of around minus 20 degrees. According to this plan, the acid used to destroy the internal secret scroll will be solidified, and the mechanism will no longer work.

"It's just that this is a bit risky, if not...... Xia Kui hesitated.

"We can't care about so much at the moment, we can only gamble, I believe him." Ji Yanran said.

She had faith in Fu Nian.

"I also agree to try Brother Fu's method." Su Yan said coldly.

"In that case, according to what he said." Xinling Jun Road.

"Xinlingjun, then leave it to me." Yang Gongxie recommended himself.

This Yang Gong evil cultivator has a technique, called "Nine Yin Xuanbing Jue", which is a rare skill in the world to the yin and cold.

Xin Lingjun handed over the Black Lotus Scroll to Yang Gongxie, Yang Gongxie held the scroll in his palm, and a wave of internal energy instantly poured into the scroll, and in an instant, a thick layer of ice crystals appeared on the scroll, and a cold air suddenly filled the entire big tent.

Ji Yanran saw that the Black Lotus scroll had been frozen, took the scroll, and a wisp of sword qi from her fingertips was injected into the scroll, and the scroll suddenly cracked, revealing the secret scroll inside.

Ji Yanran unfolded the secret scroll, but it was a picture, the deployment map of the Qin army outside the river and the location of the granary.

"But I don't know where the girl got this information?" Xin Lingjun glanced at the secret map, and then raised his eyes to look at the purple-haired woman, as if he was a little curious about how she had obtained such military secrets.

"As for where I got this scroll, I can only say that the scroll is genuine, and I don't know if the information in it is true or not." The purple-haired woman said.

Fu Nian took a closer look at this diagram, but the directions were represented by the five elements of the heavenly stems and the earthly branches, which means that the labels in the first layer of the diagram were all wrong.

Fu Nian recorded the five-line number table in the figure according to Yi Li, and then connected the five-line number table together according to the figure, and this picture presented a complex operation mode, and he pieced it together according to the five-line number table.

"How many books do you have?" Ji Yanran couldn't help but ask when she saw the number table he discharged.

"Sister Ji, wait a minute, I'm at the key point now." Fu Nian replied, still focusing on counting the table.

A and B are three eight trees in the east, three trees in the sky, and eighty percent of the earth. The number of wood spawns is eleven ......

Wuji Central Chenxu Chouwei four corners of fifty soil, five days of earth, ten percent of the earth, the number of soil generation is fifteen......

This seemed to be the reverse of the five elements, and Fu Nian knew that this was exactly the omission in his previous inference.

If his father hadn't taught him Yili before, it would have been difficult for him to solve the inverse five elements in this diagram.

Fu Nian converts the solved inverse pentagrams into an affine relationship between the horizontal and vertical axes, which is expressed in the form of a transformation matrix.

That is, by converting the matrix to the coordinates of the original point to obtain the corresponding coordinates of the new point obtained by affine, that is, the correct bit identifier.

"This picture is wrong, and you need to rearrange it according to its five rows to get the correct bitmap." Fu Nian said.

Fu Nian's words made everyone stunned, and they never thought that although this doll was young, she was proficient in these things.

This Wei State is full of talents, there are Li Kui, Wu Qi in the past, Zhang Yi, Fan Sui in the back, and now the prince of Wei is unscrupulous and conniving against Qin, I can't imagine that this child is also extraordinary.

Fu Nian then marked the correct direction in the diagram.

The woman in purple looked curious and approached Fu Nian

Beside him, staring at the picture, like a delicate girl, looking at her favorite toy.

It's just that everyone in the audience is focused on Fu Nian at this time, but no one notices her.

Xin Lingjun picked up the picture and checked it again, although he didn't dare to believe it all, but the opportunity revealed in it made his heart stir.

Opportunity on the battlefield is gambling, and if you win the bet, victory is within reach; If you lose the bet, you may be wiped out.

As a famous general, he is familiar with the changes on the battlefield, and this is his most fatal weakness.
