"What?" Tian Qianzhen was taken aback, looking at An Qingxu in disbelief, he never imagined that An Qingxu would give an order to suspend the attack when the army was about to launch an offensive against Tongguan City, he almost thought that there was something wrong with his ears and heard the wrong words!

The other generals were also taken aback, and they all looked at An Qingxu, who still had anger on his face, but had begun to become calm, hoping to hear An Qingxu's explanation.

An Qingxu of course saw the reactions of the generals in his eyes, he had no surprises, sat down on the main seat, slowly exhaled, and said with a slight dejection: "Everyone, last night's attack was fiercely returned by the Tang army at the beginning of the situation, which has already indicated that the Tang army has arrived reinforcements yesterday afternoon, judging from the intensity of each round of arrow shooting, the number of troops in the city is at least more than 20,000, according to our report of the sergeant lurking near the city wall, there is a big movement in Tongguan City at dawn, Judging from the arrogant tone of this Tang army lord named Yang Xi, there must be a large-scale reinforcement arrival, so he dares to say that!"

"Two days ago, the Tang army was struggling to support, but after the arrival of several batches of reinforcements, the situation was different, the Tang army was fully capable of making a counterattack when our army attacked, and even they could draw out their troops, taking advantage of our army's concentration on attacking the city, and had no energy to deal with other times, send a group of men and horses out of the city to attack and harass, if our army does not make adequate preparations, it is likely to be attacked by the Tang army without sufficient preparation, so we must postpone the attack, and then discuss, with a careful arrangement, before we can attack the city again! The Tang army has been basically eliminated by the impact of Lingbao's defeat, and Tongguan City is destined to be very difficult to attack, if we still attack in this way for the past two days, it will definitely be difficult to work!" An Qingxu got up again as he spoke, paced two steps, and then said: "The strategy formulated yesterday is already difficult to work, just by carrying mud and rocks, it is difficult to fill the forbidden ditch, and it is difficult to reach the sky!"

"His Royal Highness the Crown Prince is right!" An Qingxu's close general, Li Guiren, immediately stood up when he looked at the generals after An Qingxu finished speaking, and said: "Your Highness, the last general thinks that the soldiers should be ordered to cut down more trees and bamboos, and use bamboo rows or wooden rows to pave the forbidden ditch, I believe that as long as a sufficient number of trees and bamboos are cut down, the forbidden ditch will be able to be turned into a thoroughfare soon!"

In fact, Li Guiren had already made this suggestion to An Qingxu, asking Cui Qianyou to make enough bamboo rafts or wooden rafts and throw them into the forbidden ditch, so that the forbidden ditch could be quickly filled and convenient for his own men and horses to rush through the forbidden ditch and then attack the city.

But because Cui Qianyou reported before, saying that a large number of corpses were piled up in the forbidden ditch, and you could cross the forbidden ditch to enter the city by stepping on the corpses, and it would be a waste of time to make a large number of bamboo and wooden rows, and the best attack time would be missed. In the end, An Qingxu also followed Cui Qianyou's suggestion and ordered Cui Qianyou's front army to attack the city immediately, but in the end the siege did not achieve any results, and Li Guiren also raised this proposal after An Qingxu ordered a temporary stop to the siege.

"What General Li said makes a lot of sense!" As soon as Li Guiren's words were finished, Tian Qianzhen immediately stood up in support, "The forests near Tongguan are flourishing, it is very convenient to make a large number of wooden rafts and bamboo rows, it only takes half a day to complete the required bamboo and wooden rows, and after filling the forbidden ditch with bamboo and wooden rows, the forbidden ditch will become a thoroughfare, and then concentrate all the troops to attack in turn, and it will definitely be able to break through Tongguan City!"

An Shouzhong also immediately stood up and expressed his support for Li Guiren's proposal.

To tell the truth, many people did not think of cutting down bamboo and wood to make bamboo and wooden rafts, and using bamboo and wood rafts to fill the forbidden ditch, they thought of filling the forbidden ditch with soil and stones, and wanted to fill the forbidden ditch permanently with a huge force of more than 100,000 horses.

The forbidden ditch has been filled, and all the hundreds of thousands of horses can be gathered to launch a tide-like offensive against the city wall in the direction of the south gate, and directly attack the head of Tongguan City in one go.

But last night's attack proved that this method was not very feasible, after all, each sergeant could not carry much mud and stones, and he had to suffer from the dense arrow attack of the Tang army.

But the bamboo and wooden rafts are different, the volume is large, and it can also be used as a shield in the transportation process, even if there is a gap in the middle after throwing it down, it will not necessarily affect the passage, the required number is much less, and hundreds of bamboo and wooden rows can basically set up a passage. As long as you think of this, you will definitely agree with this proposal.

No one stood up to oppose it, and An Qingxu seemed to be encouraged, as if victory was in sight, and he did not hesitate to immediately give an order, ordering the sergeant to hurry up and cut down trees and bamboo, and make thousands of bamboo and wooden rafts, which must be made before noon.

After An Qingxu's order was issued, the generals also immediately went to make arrangements.

For a time, the vicinity of Tongguan was full of soldiers cutting down trees and bamboo, and the vegetation near Tongguan in eastern Huashan was extensively destroyed.

"Marshal Yang, you are really a god, after a few letters were shot into the rebel formation, the rebels actually stopped attacking!" When the sun rose, but still did not see the rebels begin to attack the city, but the sergeants on standby retreated a certain distance, Wang Sili couldn't help but say the exclamation in his heart, he wanted to know what Yang Xi said in the letter, but it was not good to inquire directly, so he could only implicitly express his inquiry.

"Ben Shuai's letter is just a delay in the army, I hope that after An Qingxu sees the letter, he can temporarily dispel the idea of attacking the city, it seems that it really works!" Yang Xi looked back at Wang Sili, who had some surprise on his face, and then at other generals with similar expressions, and said with a smile: "But An Qingxu can't stop there, the more than 100,000 horses under his command are not decorations, these are border troops who are good at fighting, they will definitely find a way to continue to attack the city!"

After hearing this, Pang Zhong on the side couldn't help but express the doubts in his heart: "But marshal, the forbidden ditch danger has been restored, and the rebels' plan to transport soil and fill the city when they attacked the city last night has also been abandoned, it is difficult for them to cross the forbidden ditch natural danger, An Qingxu will not attack while our army is weak, and when my follow-up reinforcements arrive, how can he still attack the city?" ”

Yang Xi looked at the array of rebels in the distance, sighed and said: "The rebels know that the forbidden ditch is extremely difficult to cross, so they wanted to transport soil to fill it when they attacked the city last night, but they gave up this idea after being hit by our dense arrows, but this move also shows that the rebels want to fill in the forbidden ditch before attacking!" The rebels will definitely not give up this idea, let alone stop the war and withdraw from Tongguan!"

"Then, Marshal, what do you think the rebels will attack?" Sima Tian Liangqiu, the former marching army who had been silent, couldn't help but ask.

Yang Xi pointed to some rebel sergeants who were faintly visible in the distance and were trying to cut down trees, "You see, the rebels have begun to cut down trees on a large scale, presumably they are preparing to make more ladders, as well as things that can be paved such as wooden rows, if this marshal is not bad, the rebels must want to use wooden rows and the like to fill in the forbidden ditch, and after the forbidden ditch outside the south gate is filled, then attack the city on all fronts!"

"What?" After hearing Yang Xi's words, all the generals were shocked!

"There's nothing to be afraid of, Ben Shuai has already found a way to deal with it!" Yang Xi said, quietly saying his thoughts.

"The Admiral understands! Get ready now!"

After listening to what Yang Xi said, everyone suddenly realized and immediately prepared according to Yang Xi's instructions.
