In fact, neither side can afford to delay. Needless to say, Cao Cao was able to be self-sufficient before because of the grain output of Herat and Kandahar.

Compared to Kushan who could only transport grain from Kandahar to Herat at that time, Cao Cao could at least carry out military farming in Herat, so it was okay to provide part of the grain output.

In addition, although the water conservancy construction in Kandahar has not been completed, it can provide a considerable amount of food and grass. Therefore, when no one attacked Herat, Cao Cao himself could basically be self-sufficient, but if he was attacked, there would be no output.

If the water conservancy construction in Kandahar is completed, Cao Cao can transport grain from Kandahar to Herat like Kushan. Even if the loss of grain transport in the desert is very large, Cao Cao can still hold on in a short period of time. However, the construction of the water conservancy network in Kandahar has not been completed, so Cao Cao has to go to the desert to transport grain and grass.

This is why, when Cao Cao's food and grass were barely self-sufficient, Cao Cao would ask the Wei family to purchase some food and grass from other places from time to time. It was not that it was really not enough, but that it was more realistic to use it as a reserve.

But overall, once Herat is attacked, there will definitely be problems with Cao Cao's food and grass. When the Kushan food and grass logistics were so strong, Cao Cao fought several games with Herat and Kapil, and Kapil was forced to give up Herat because of difficulties in transporting food and grass.

How could Cao Cao's logistics level be comparable to that of Kushan, who owns the Ganges Plain? Therefore, when Gumara pointed out this fact, Barak was inevitably a little irritable.

Because I have fought here, I know that this problem really exists. Even if reinforcements arrive in Herat, Aldashir will continue to slap here, and it will not take long for Balac and others who are inadequate in food and grass to find a way to return to Kandahar.

From a certain perspective, although Herat is natural and dangerous, it is not so easy for Beigui to defend. This is why in official history, this place is often a resting place, because after Herat occupied Herat, the transportation of food and grass was much easier than that of Kushan.

"It's so uncomfortable." Barak breathed, and he also knew where the problem was now. After Herat was attacked, Kandahar would not provide much assistance.

"Ardashir is also limited by food and grass, and after he chooses to take action, the Han army's eyes will also fall on him. The Xiliang Iron Cavalry on the other side of the Pamir Mountains and Lu Xun in the eastern Caspian Sea will stare at him, so he is also impossible to waste it." Gumala shook her head and comforted her.

"I'm thinking about how to deal with Ardashir." Barak's expression became much more serious.

It is not realistic to fight head-on. Even Barack at his peak is unlikely to block Aldashir head-on. If Ardashir is better at patience than them, the situation may be more troublesome, so overall, the situation is quite uncomfortable.

"Actually, I suggest to give up Herat." Gumara spoke slowly, and Barak was stunned. It was Gumara. If someone else dared to say this in front of Barak, Barak would definitely regard the other party as a 25th boy. Gumara and Barak have known each other for many years and know the truth. Only he can say this in front of Barak.

"Tell me why." Barak looked at Gumara with a calm expression.

"I can't hold on. Ardashir's attack must have Visuteva I'm behind the scenes. We all know that the diplomatic methods of that person are not that simple." Gumara pointed out the situation directly, and Barak nodded when he heard this.

This is true. Based on Barak's understanding of Vesutva I, Ardashir took action at this point. It would be impossible for Vesutva I to rush back.

"What do you think is the greatest possible support if Vesutva I gave?" Gumara looked at Barak with a calm expression, and Barak reacted instantly.

"It's that guy Osven." Gumara sighed and gave the answer directly.

"Kapil is not a fool. The most effective way to do this time is to build a dam in the upper reaches of the Helmand River." Gumara said with a sigh, "If Xun Wenru is indeed a genius, he built a fortress upstream as soon as possible after capturing Kandahar. I'm afraid he also saw the combat method that Kushan might have chosen, but the time is too short."

The Helmand River belongs to the rivers formed by the snow melting in the mountains. The water volume is not very large, and it is considered to be a multi-source type. Xun Yu may also realize that the water flow of this river is not large, and they are going to use this water network to build water conservancy facilities, so they are prepared early to build fortresses upstream of the water system, so as to ensure that they are not allowed to be sourced by Kapilka as much as possible.

Of course, it is impossible for Beigui to completely get stuck in Kandahar's water source. Even if Xun Yu did not prepare in advance, Beigui's could not completely cut off the Helmand River. It can only be said that the runoff is reduced, resulting in the planned irrigation area in Kandahar area not having enough water sources to use.

Of course, drinking water and other things are not necessary to consider, this is absolutely enough.

After the upstream river water was blocked, there must be problems with water use downstream. Afghanistan and Iran had great problems in the distribution of the Helmand River. The reason was that Afghanistan built a dam in the upstream and intercepted a large amount of river water, resulting in insufficient water resources in Iran for agricultural irrigation.

This is a hooligan trick. If you die, you won’t be fatal. But if you delay it for a long time, there will definitely be bigger problems with the grain and grass logistics that have already had problems with Cao Cao.

"Xun Wenruo and others probably realized this problem, but they definitely couldn't think of how Kapil and the others would block the water source." Gumala said with a laugh and cry. There is no need to build a dike at all, it only needs to be modified at the source. After all, this river is the result of snow melting in the mountains. It is difficult to block a large river, but it is not difficult to block dozens of streams in the valley.

Isn’t this just taking some time for Beigui? By blocking dozens of valley streams, the runoff of the Helmand River will probably be reduced by half. It would be strange if Cao’s army was not confused at that time.

"So the real enemy is not Ardashir, but Osven." Gumara sighed and said. Perhaps for others, Ardashir is more dangerous, but Gumara is very clear that the interests of both sides are not consistent.

All Ardashir wants is a place to settle down. For Gumara, he just gave it to the other party directly. Even as long as they did not have a conflict with Ardashir, they could continue to talk later. After all, Ardashir is just a knife, and the knife holder can be Vesutva I, so why can't it be Cao Sikong?

Really, if the alliance between Ardashir and Vesutva I is very strong? What a joke, if you beat Beigui and let Ardashir go, at most two months, Vesutva I will have doubts. The interests of both sides are only consistent in stages, not really the same.

So there is a lot of room for operation. For Gumara, letting Ardashir take Herat, and they lead their troops back to Kandahar and concentrating their strength to attack Osven is also a good choice. To be honest, as long as the Han Dynasty and Ardashir do not completely turn against each other, there will be some operations. As for liquidation, it will not be too late to talk about it in the future.

"Are you worried that the rescue of the Han Dynasty will not come in a short time?" Barak's expression became much more serious. If this were the case, Gumara's suggestions would be really worth thinking about.

Without the Han Dynasty to support it, it is basically meaningless to stick to Herat, but it will further increase the loss of food, resulting in an otherwise ungood situation and worse.

"Yes, I'm worried that in the next three months, we will not be able to wait for the rescue of the Han Dynasty. Major families in Central Asia will definitely stop. The Pamirs and eastern Caspian Sea will probably collapse. They all need time to clean up." Gumara said with a calm expression.

Barak was silent for a while after hearing this, and finally shook his head. Gumara's suggestions were indeed good, but he could not accept them. Moreover, the Han Dynasty was different from the dynasties afterwards. There was no precedent for not fighting in a battle and abandoning it directly. If you can't beat it, it was a human problem. If you give up before fighting, it was really a mental problem.

"But once I fight with Ardashir, I will have to give up Herat sooner or later." Gumara sighed and said, "Osven must be fighting for his life now. After the changes in the sky, only a very small number of the royal gun and shield soldiers in the Sahel remained at the level of the Imperial Guards, and some even collapsed to the level of a single talent. Do you know what this means?"

"What does it mean?" Barak didn't understand what Gumara was saying.

"It means that the legions under Osven's command have become much faster, and they have become much stronger in comparison." Gumara sighed and said.

"The Imperial Scepter pulls two talents to the Imperial Guard, which is much easier than pulling the Imperial Guard to three talents. Moreover, the Imperial Scepter does not need to retain a blessing space for itself. It is equivalent to an Imperial Guard!" Gumara looked at Barak with a sigh, while Barak and Sahel were much silent.

"The change of heaven is a fatal blow to many forces, but it is not for us, the Great Yuezhi people from the north." Barak also reacted. They implemented the military system of the Qin and Han dynasties, which was year after year of military service. Although it is unlikely that the double talent is possible, after the single talent achievement, the change of heaven is impossible to affect the old people among them.
