Hearing the system voice in his head, Su Mo was slightly stunned.

"Option one, gather border soldiers and horses, defeat the million-strong army of the Huns, and reward the red-coated cannon enhanced version of the design blueprint."

"Option two, use guerrilla tactics to attack the small tribes of the Huns to alleviate the logistical problems, and reward five million stone grain!"

The choices given by the system have their own advantages and disadvantages for Su Mo.

Gather border soldiers and horses to defeat the million-strong army of the Huns.

There is a gambling component to such a choice.

After all, it is winter now, the climate on the grassland is harsh, the environment is worrying, and it is not yet known whether the border soldiers and horses can adapt to the grassland.

Once the border army penetrates deep into the grassland, it will be a situation of non-stop, and it will be difficult to withdraw safely.

If the army is mobilized in the autumn, Su Mo will naturally not have any concerns.

Even if the 100,000 cavalry under his command cannot win, he can reorganize the army and go deep into the steppe again.

But today's conditions are holding him back.

The storage of cotton clothes, battle armor, weapons, and winter combat materials needed for logistics support at the border is only suitable for troops with less than 100,000 people.

Once more than 100,000 cavalry on the border were mobilized.

At least 300,000 soldiers and horses are needed for logistical support.

The stronghold guard, the supply of supplies, which means that he needs to mobilize more than 400,000 troops.

Winter marches already require a lot of food and grass.

The food and grass needed for an army of 400,000 was twice as much as it would be on a normal day.

This is too much pressure on food at the border.

People went deep into the grasslands to solve the food crisis.

Large-scale troop movements are not conducive to defusing crises, but rather carry endless risks.

The other option is completely different.

The use of travelogue tactics to attack the small Xiongnu tribes to alleviate logistics problems is a move with little risk and a high probability of success.

For the border army, it seems that it should be the best choice.

30,000 cavalry faced the encirclement and suppression of millions of troops, firing a shot to change places.

Then they used their mobility to rush away, and it was difficult for the Huns to catch up.

In addition, the troops under Su Mo's command all have compasses, so there is no need to worry about getting lost in the Xiongnu steppe.

The most important thing is that the guerrilla tactics of 30,000 cavalry do not need to provide food, grass and logistical support from the border at all.

Wherever they went, the Huns had no choice.

It's just that the reward given by the second option is a bit poor.

If five million stone of grain had been given before, it might have been somewhat attractive.

However, not long ago, Su Mo had just obtained Tianlong rice seeds.

Such an existence is not enough for Su Mo.

Five million stone of grain is enough to survive this winter, but it is not enough to completely solve the food problem at the border.

As for the design drawings of the redcoat cannon, it is the best choice.

According to the description of the system, this red-clothed cannon is a strengthened version, which is specially used to kill and injure cultivators.

A red-clothed cannon was enough to intimidate a cultivator of the Minor Grandmaster Realm.

If the red-clothed cannon is established on a large scale, even the realm of heaven and man can only become the soul of the cannon.

Once such a weapon is introduced, the impact on the Kyushu continent will be subversive.

It is also a subversive change for the combat power bonus of the border army.

The drawings given by the system are based on numerous tests.

Both durability and power have been tested, and it is an excellent choice for Su Mo.

After all, there is only an arsenal in Tai'an City now, and there are no drawings.

This has also led to the stagnation and slow progress of firearms research.

The blueprints of the red-coated cannon will give everyone a reference, so that the research of items such as firecrackers can be further advanced.

Not only that, but such equipment can also accumulate experience for his craftsmen.

Maybe next time I can make rapid progress and develop some current firearms and so on.

Just when Su Mo was about to inform everyone of the decision, Chen Wu and Cheng Meng had already had a dispute over the follow-up tactics.

Chen Wu, who had previously gone deep into the grassland, believed that an ambush should be set up against the Xiongnu cavalry first.

Find a way to kill the enemy's commander or commander so that the crisis can be resolved.

As for Su Mo's subordinate Cheng Meng, he believes that he should take the initiative to attack and directly kill the local general.

Then discuss whether to retreat or fight, and Chen Wu directly refuted Cheng Meng's suggestion.

"We only have 30,000 cavalry now, the logistics line is completely broken, and the supply of soldiers depends on the Xiongnu tribe."

"In such a situation, if it is a head-on attack, it is a gamble, and I will not approve of the lives of 30,000 soldiers!"

As for Cheng Meng, he immediately retorted: "Gambling? How can 30,000 people fight an army of 1 million without gambling? ”

"Are we going to wait for their multimillion-millions army to catch up with us? Isn't that also gambling? ”

Hearing Cheng Meng's defense, Chen Wuqi's body trembled slightly.

How are guerrilla tactics gambling?

This is reasonable risk aversion.

If it is according to Cheng Meng's justification.

Any war is a gamble, betting that the other side will lose to yourself.

Such remarks are hooligans and scoundrels in his eyes.

After thinking about it, he immediately retorted: "There is no need for 30,000 people to attack head-on, the consumption of grain and grass by the opponent's million-strong army is unimaginable, as long as we take advantage of the chaos to destroy their logistics line, this million-strong army will not be able to attack itself." ”

"At that time, not only can you easily defeat the Right Virtuous King, but you can also continue to hunt the grassland and get cattle and sheep!"

Cheng Meng pointed to the map and asked, "Logistics line?" Tell me where is the other party's logistics line? ”

"This grassland is so big that you can't see the edges, and it will take at least half a month to find their logistics line!"

"Can the people at the border afford to wait for half a month?"

His words immediately stopped Chen Wu.

He had only considered how the frontier army could minimize losses, completely ignoring the purpose of the crowd going deep into the steppe.

The reason why they ventured into the grasslands in winter was to obtain cattle and sheep and relieve the pressure on food on the border.

In normal times, it was best for him to cut off the logistics line and attack the Hun cavalry in the steppe.

Because the other party has to take into account the safety of various small tribes and nomads everywhere.

30,000 cavalry on the steppe, with absolute initiative.

It only takes half a month to find out the logistics line of the opponent's million-strong army.

At that time, he will be able to slowly cut off the logistics supply of the million-strong army, and then drag the other party to death.

This is also the tactic he used when he went deep into the grasslands before, and it has been tried and tested many times.

It is precisely because of this that he sticks to his tactical line of thought and does not want to fight head-on.
