Faced with this phenomenon, Cao Cao no longer dared to march rashly, so he could only lead a large army to return to the camp in a hurry. The military doctor immediately diagnosed and treated the poisoned soldiers, but did not find out the cause, and the symptoms tended to worsen, and several people had difficulty breathing and fainting.

Everyone was in a hurry, and there was no cure for it, but after a few hours, these people were miraculously all healed, as if nothing had happened.

"Zhang Lu actually has such a skill, but I underestimated him." Cao Cao sighed and said, victory is in sight, but it is blocked by a cloud of fog, not only blocking a qiē, but also unable to move forward, which is really unwilling.

Except for Wang Baoyu, no one knew how to spell, so all eyes were focused on him, and Cao Cao was also full of expectations, but he begged again and again, and was a little embarrassed to speak.

Wang Baoyu thought for a while and took the initiative to say: "Lao Cao, I don't dare to say that I can break the black fog, but I have learned a method, but I can try it." ”

"Baoyu, all soldiers can be dispatched by you!" Cao Cao hurriedly promised.

"Hehe, there's no need for that. Still, thank you for your trust. Wang Baoyu said politely.

"This expedition is thanks to Baoyu accompanying him all the way. Otherwise, victory or defeat is still unpredictable. Cao Cao first sighed.

"We also help each other, and I still have to rely on you for things going north." Wang Baoyu smiled and didn't forget to remind.

Cao Cao was speechless, he was really reluctant to let Wang Baoyu go, but looking at his determined posture, he was afraid that he would not be able to keep it in the end.

Why are there such people in the world who do not love power? If Wang Baoyu was willing to stay to help him or assist his son in the future, Cao Cao could stop there, give up Bazhong, and not be in a hurry.

The method that Wang Baoyu wants to use is, of course, the white bone arrow, but he doesn't know if it's easy to use or not. That night, Wang Baoyu closed the camp tent and ordered no one to enter, saying that it was to destroy the enemy, and then turned off the lights.

Everyone knew Wang Baoyu's ability, and no one dared to disturb him, but they didn't fall asleep either, waiting for a miracle to come again. Last time, a tiger came, maybe this time it can fly out of a phoenix, and two flickers of its wings can drive away the black fog.

In fact, Wang Baoyu didn't do anything in the house, but lay on the bed to rest. All his actions were to confuse everyone, and he had already handed over the white bone arrow to Fan Jinqiang, and asked him to quietly rush to the vicinity of Bazhong City in the middle of the night and give it a try at the black mist.

Because the black mist is poisonous, he can't get close, and with Wang Baoyu's arm strength, he can't pull the bowstring, and this task is none other than Fan Jinqiang. At the same time, he was told to stay away, not to be poisoned, and to put safety first.

In the middle of the night, Fan Jinqiang slipped out of the camp on horseback and quietly came to the vicinity of Bazhong City alone. The black fog was really still there, just like the eyes of the night, pitch black, and even more indescribably gloomy and mysterious, even Fan Jinqiang felt a chill in his back.

Fan Jinqiang decisively took out the Sky Shooting Bow, put the white bone arrow on it, and pulled the bowstring, only to see a white light, and the white bone arrow flew towards the black mist.

A very unbelievable phenomenon happened, the white bone arrow seemed to be shot into a ball of glue, and it was actually fixed on it, and it did not fall.

Fan Jinqiang didn't know what to do for a while, he wanted to go over and take it off, but he was afraid of being contaminated with poisonous gas, if he didn't take it back, wouldn't it be a pity if the good brother's baby was taken by others?

In the entanglement, he waited like this for half an hour, and suddenly, a trace of white gas appeared on the white bone arrow, which infected the black mist.

There was more and more white gas, and soon it became an overwhelming situation, gradually engulfing the black mist until it disappeared, and the white gas also disappeared, and Bazhong City once again appeared a clear outline.

The white bone arrow fell straight down on the side of the moat, Fan Jinqiang hurriedly went over and picked it up, carefully hid it in his arms, and quickly left the place.

Hearing Fan Jinqiang's report and seeing the white bone arrow again, Wang Baoyu was very happy, this is really a good thing, not only can it break the black fog, but it can also be used repeatedly, Zuo Ci is really righteous enough.

The task was completed, and Wang Baoyu slept peacefully, but Zhang Lu in Bazhong City heard the report that the black fog had disappeared, but he was so worried that he couldn't sleep anymore.

The good things left by the ancestor are only such a poisonous mist talisman, and it is also the last barrier he can use, even if this barrier can only last for seven hundred and forty-nine days. However, now in less than a day, it was actually broken by Cao Jun, which is incredible.

Who are the masters in Cao Ying? Zhang Lu couldn't help but think of a person, it was the kid riding the tiger, Cao Cao's first army division Wang Baoyu, except for him, I was afraid that no one could break this spell. Alas, the magic is one foot high and one foot high, this kid's ability is really unfathomable!

Early the next morning, Cao Cao had just gotten up when he heard a report from the spies that the black fog surrounding Bazhong City had completely disappeared.

Cao Cao was excited, and immediately rushed to Wang Baoyu's big tent, woke up Wang Baoyu, who was still sleeping, to express his sincere admiration and gratitude, and then joined him to march quickly and launch a full-scale attack on Bazhong City again.

"Cao Bing is here!"

Hearing the report, Zhang Lu, whose eyes were red, sighed, although he could barely support it for a few days, he didn't have a trump card in his hand, and finally the general trend was gone.

Knowing this, I really shouldn't have been a king with a hot head, I should have surrendered to Cao Cao as soon as possible, maybe I could keep the land of Hanzhong, tossing until now, even if I surrendered, whether Cao Cao was willing to let him go has become an unknown.

"Report! There is a large army in Jiamengguan, which is coming to Bazhong. ”

Zhang Lu was taken aback, he didn't expect Liu Bei to come to attack, didn't he say anything about sharing wealth and wealth before! This person is really not credible, but fortunately he didn't defect to this guy.

At this time, the strategist Yan Pu walked in and arched his hand: "My lord, according to the secret report of the servants of Yang Song's mansion, when Yang Song was in Nanzheng, he had a private meeting with Cao Cao's Military Academy and accepted gifts, and the evidence is conclusive. Such those who turn their backs on the Lord and seek glory must not be kept! ”

Zhang Lu let out a long sigh, and before and after contacting, he suddenly realized that the real reason why Pang De defected to Cao Cao was to force this villain away. Zhang Lu thought for a while, waved his hand decadently and said: "Killing him at this time is to be an enemy of Cao Cao, and I have my own thoughts on this matter." ”

"Lord, the Cao army is attacking again, it is better to order the army and the people to defend the city together, or they can hold each other for several months." Yan Pu built yì road.

"Alas, don't let the people take their lives again. Yan Gong, I bother you to go out of the city to see Cao Cao, saying that I want to surrender, but ask Wang Baoyu's military division to enter the city to discuss. Zhang Lu said.

"Lord ......"

"Liu Bei sent troops to Jiameng Pass, and now he is under the enemy's back, if he hesitates, you and I will not be able to save it. I have made up my mind, and I don't need to be persuaded again. Zhang Lu said firmly.
