Hu Yongsheng slowly walked out of the big tent, standing in the yellow sand, looking up at the blue sky.

The pure blue color contrasts with the endless yellow sand. Because there is no shading, the light is extremely harsh.

The more time wasted in the vast desert, the more unfavorable it was for the Han army, and they could stay in the enemy's territory for one less day, and each additional day of stay could be more dangerous.

We have to think of a way to do it.

Hu Yongsheng withdrew his gaze from a distance and landed on the flagpole with a nearby pestle on the ground.

Under the scorching sun, the flagpole formed a slender shadow on the ground, and Youmei phoenix stared at this shadow for a long time, as if she remembered something.

"Report! General, general, the probe has returned. ”

The two horses were helped into the tent to discuss the war, and this was the third group of horses sent to explore the horses, the first two groups returned in vain, and they almost lost their lives and lost their lives.

After a while, the tanma was helped out again, just passing in front of Hu Yongsheng, the two tanma ran on the scorching yellow sand for two days, lost too much water, chapped lips, and severely sunburned skin, and could barely pace by supporting.

"Hey, Tanma is back, and he hasn't brought any good news."

"yes, it's nice to come back alive."

The two camp guards were talking in a low voice, and suddenly saw Hu Yongsheng, and one of them poked the servant who was standing aside.

"Fuduo, it is also the barracks that participated in the competition, you look at the people, leisurely, and then look at you, like us, you are sunburned into carbon under the sun."

He glanced in the direction of their gaze, then withdrew his gaze and continued to look in the direction he was guarding, his expression unchanged.

One of the guards rolled his eyes and said in a strange way, "People have to die more than people, and goods have to be thrown away." Someone else's life is good to become the younger brother of the hussar general, and one person is promoted to the rank of chicken dog and ascends to heaven. ”

"This kid is useless at first glance, he can't be anbang, he can't be convinced by martial arts, he has no power to restrain chickens, he has no skill in cutting his body, and he really has no merit except for having a good face."

The servant who hadn't spoken for a long time pursed his lips lightly, "Huo Guang won the triathlon competition, not because he was powerless. ”

Hu Yongsheng stood not far away and took in their conversation, striking iron still needs its own hardness, no matter which team, if you want to serve the public, you must have your own ability, he smiled helplessly, and walked in front of a few people.

"Excuse me, where can I find a stick or a bamboo pole that is about the size of a flagpole."

Because they didn't expect Hu Yongsheng to come over suddenly, the two guards who were originally going to continue chewing the root of their tongues closed their mouths suddenly and looked away in a panic.

Still expressionless, he pointed in the distance, "There's a spare flagpole there." ”

Hu Yongsheng quickly found a satisfactory pole and returned to the position in the center of the spacious camp just now.

Look up at the position of the sun and firmly stand the pole in the middle of the yellow sand.

"Drop~"

"Congratulations to the host for opening the brain hole skill."

Brain skills?

Poof, Hu Yongsheng almost laughed out loud, can the name be a little more vulgar.

Hu Yongsheng hooked the corners of his mouth and placed a stone on the top of the shadow. Then I began to recite the numbers in my mind, and then observed the distance the shadow moved.

The shadow moved with the movement of the sun, and for about fifteen minutes, another stone was placed at the top of the pole projection.

He crouched on the ground and drew a line between the two marker points and a vertical line in the middle of the straight line.

The second marked point is east and clockwise marked south, north, west, and west.

"Congratulations to the host brain hole skill for improving LV1 (8/10)."

"The host can open the brain hole skill and appreciate in such a short period of time, and if the host can make an invention that is beneficial to this battle, the system can also get points."

"If my invention is successful, you can also get points?" Hu Yongsheng made a small cross and fixed it in the position just marked.

"Yes, host. The points of the system are based on your achievement points. Achievement is different from the host's own stats, and is based on the host's current achievements. ”

"That's it!" Hu Yongsheng walked as he spoke, and had already returned to the big tent.

"So, whether the system is upgraded or not depends on the host."

Hu Yongsheng suddenly had a sense of joy that he was working hard outside to make money, in order to support his own woman, so that she would always be as beautiful as a flower.

Speaking of women, he suddenly remembered that Xiao Yue, before getting the system prompt to wait for the "opportunity to enter the office" under the tree, he went to look for Xiao Yue, but Liu Ma and Xiao Yue were nowhere to be found, he asked the neighbors around him, and he didn't know where they went, thinking of this, Hu Yongsheng's heart was a little sour.

Just after a while, Hu Yongsheng re-engaged in a new task, patting his chest, "It's so simple, five words floated in the sky." ”

"What?"

"That's not a problem!"

System: "......"

Hu Yongsheng didn't brag, he thought of a way to travel in the vast desert without deviating from the direction.

There is no compass here, no GPS positioning, and you can only rely on the rising and setting of the sun to identify a general direction, but in the march, this more general direction can easily cause deviations.

He had to find a way to make a guide that could be mounted on a combat vehicle.

This kind of station train should be able to point south at all times. It does not change depending on the direction of travel.

Hu Yongsheng took out a piece of silk and began to draw the composition in his mind with a pen.

I didn't expect that I, a science and engineering dog who studied mechanical design, could also use the knowledge of going to university in the Western Han Dynasty.

Hu Yongsheng is most fortunate that he did not waste his time in college, he is not a scholar, but he is definitely one of the few in the class in professional courses, and he is also engaged in his major after work, and he is going further and further on the road of science and engineering dogs.

If you really learn anything, you can't learn it in vain, maybe you will use it when you can.

Yes, he is not a science and engineering dog now, but a prince and general who is about to reach the pinnacle of his life and marry Bai Fumei.

Although Hu Yongsheng has a lot of information about his own design, it is only when the mule comes out to slip that he knows, and the operation is feasible, which is really feasible.

I didn't want to delay for a minute, I didn't find the Huns, but they are still on the battlefield, and time is precious.

Hu Yongsheng strode out of the tent.

Ding Bang Bang, Ping Pong Chang, ##¥%¥#%%##

10,000 words are omitted here......

Gongsun Ao was furious and hurriedly broke into Huo Quai's camp.

For Gongsun Ao, the boss of this expedition is the nephew of his friend, who does not look at the face of the monk but also looks at the face of the Buddha, and is also his own family.

Although this "little boss" is only 19 years old, he is indeed extremely brave, and he is a rough man, but he followed Huo to get sick and was convinced.

This time, Huo Quai's younger brother who passed by his hometown and brought back looks handsome, and he is also polite in his life, why did he go crazy today.

"General Huo, you go and see your brother, he has dismantled our two chariots, and I don't know what he is doing."

If we are in our own home, we will dismantle Dad's two bicycles, who cares if you change them into wheelchairs or directly turn them into stretchers.

But this is a battlefield, and every grain of rice, every horse, and every chariot brought by the army is a military quartermaster, and if it is damaged at will, it can be directly beheaded according to military law.

Huo Quzhi heard Gongsun Ao's angry complaint, his eyebrows tightened, he didn't say anything, and strode out of the tent directly.

Because Hu Yongsheng was the younger brother of the hussar general Huo Quai, others just looked unhappy, but they didn't step forward to stop him.

That is, Gongsun Ao yelled at him a few words just now, but he was retorted by him lightly.

At this moment, Huo Quzhi had already walked behind Hu Yongsheng, but he was completely immersed in his "invention and creation" and didn't know anything about it.
