As the village saying goes, "How capable you are, you are not as tall as a rake of cow dung." Cattle are indispensable livestock in the village, and the amount of forage that cattle eat every day is also massive, so there are many cattle grazing, and cow dung is often seen on the side of the road.

But cow dung is a good fertilizer for the villagers, reluctant to burn, Zhang Heng has only seen burning toilet bamboo before, the old people take green bamboo, that is, the most common bamboo in the south, the outer layer of bamboo for weaving, this layer with cyan bamboo skin, tough surname, not easy to decay, more water, can be burned shaped, but the corresponding will be very sharp, used to wipe the butt will cause irreparable ** and double trauma to the soul!

But the white layer in the bamboo is relatively soft, do not cut the hand, the thickness is also there, take a centimeter wide or so into strips, put in the toilet, use directly with the hand to intercept the line, children's strength can also be easily broken, and the length can be decided according to their own preferences, the concept of "self-help" has long been deeply rooted in the countryside.

After convenience, these bamboo pieces will be burned regularly, and the smoke has a deep gray, although the bamboo smell can cover up the smell, but the smoke disperses but does not gather, and cannot rise directly to the sky.

Shaking his head, he quickly swept out of his mind what he had seen and heard about going to the toilet, but he couldn't help but write a note explaining that the big pillar was drawn with bamboo slices, and promoted the beautiful things such as primitive people wiping their buttocks with soft bamboo slices...... Belch!

And thinking of cow dung, he wants to find cattle to farm, so that with the output of cattle labor, he can completely liberate men to fight, but I don't know the cow head tribe, whether the word "cow" in the pronunciation refers to this kind of modern cattle, as well as "horses", if you want to conquer farther areas, mounts are irreplaceable, Ah Qi's camel beasts, endurance has, but can not go down to the paddy field, can not replace the cattle, can not run fast, can not be used as a mount.

"Let the big pillar break the bamboo piece and teach everyone to solve the problem of wiping the buttocks!" Su Xiu looked at the note and was speechless for a long time, is there a difference between men and women in the young king's thoughts? How could this kind of thing be said so directly, how could she tell Da Zhu in a different way.

The smell spread, the smoke came out, but it wasn't much, and it had to wait for more branches under the wolf dung to burn, Su Xiu thought about it and handed the note to Dazhu, but Dazhu couldn't finish the words at all, and in desperation, he had to let Su Hong explain, and when Su Hong finished speaking embarrassedly, he found that he had thought too much, Dazhu nodded seriously, and hurriedly ran to do it, not feeling embarrassed at all.

I can only sigh that they are really two brothers, these surnames are so strong!

Zhang Heng in reality was suddenly stunned, and his eight-point consciousness descended into the stone statue, but he did not break the stone statue, because he was at work at this time, which was not very convenient.

As far as the eye can see, the smoke from the three bonfires rises almost at the same time, and the effect is almost the same, less than a meter apart, the smoke is actually entangled, and finally converges into one place, Zhang Heng's expression can not change, but there is consternation in his eyes.

Because the smoke is bloodshot and has a pale red state, it can be seen with the naked eye alone.

"Bloody!" Zhang Heng muttered.

The fire is getting stronger and stronger, and the smoke is getting thicker and thicker, gradually rising into the sky, showing a vision, as if emitting a blood mist, which looks a little bewitching, but more of it is still a killing atmosphere, which makes people feel a little blood boiling illusion at a glance.

But before the smoke completely rose into the air, it gradually faded, not blood but smoke, at a glance, it was the firewood below that was completely burned, and how could smoke be produced when the open flame came out.

Zhang Heng didn't write a note to say hello, but he felt that the expressions of the Su sisters were a little strange, why did they pinch their noses, could it be ~~ This smoke stinks?

Gradually, there were more and more open flames, and the fire on the left was completely gone, only a trace of blood-colored smoke was rising, and it kept drifting upward, but the higher it was, the more it could not be seen, and then there was a pile in the middle, and finally the three bonfires became prosperous fires, and the smoke completely dissipated, leaving only blood-red smoke to be extinguished.

Zhang Heng nodded, eight points of consciousness fell into reality, looking at the information displayed on the computer screen, some other traces of plant burning were found on the remains of the beacon tower, which proved that the beacon tower not only burned wolf dung, or did not burn wolf dung. As for why many data show that the smoke from wolf dung is very light, I am afraid it is because of the breed of wolf.

There is no blood wolf in modern times, but who can guarantee that there are no blood wolves or other more special wolf species in the ancient times of the earth, and the wolf can become the totem of some peoples, and it must have its inevitable surname.

Shaking his head, thinking that these were of little use to him, a smile appeared on the corner of his mouth, as long as the blood wolf feces in the primordial space could burn out special wolf smoke.

Immediately called Wu directly through a note, let Su Xiu translate for a while, and then after three days of combination verification in the original space, he finally preliminarily settled on a recipe with burning smoke, using tree branches with branches and leaves like cypresses, adding a special kind of hay, which can burn a fairly thick and long-lasting smoke, and then put a certain amount of blood wolf feces into it.

This burning state made Zhang Heng a little shocked, as if he had burned out a giant with the sky above his head, exuding a terrifying blood-red killing aura.

Qin Shou, Yuming, Wind, Jiang'an, Bugu, Dark Yeqi, Blood Wuyao, Nannin, Sneer, Barbarian...... The men moved, and ran in all directions with the team, the blood mist kept rising, and the men ran separately to test how far they could see the blood mist.

Until the men returned after dark, the blood mist was also extinguished at this time, and when Su Xiu collected the men's language, he finally got an exaggerated answer, all the men saw the blood mist far away, and it was clearer.

Zhang Heng can be described as overjoyed, and explained that Wu arranged to continue the test, simply went directly to contact the Kui tribe to test together, and also used the feces of other animals, as well as more plant combinations to burn, if it is really feasible, smoke will be a tool for him to issue orders in the future, different smoke represents different orders, such as: hunting, danger, market, beast tide, summoning, etc., can be achieved through smoke.

Moreover, before the winter of this year, he was going to slaughter carnivores within a radius of dozens of miles, and the gathering was a big problem, if the smoke was gone, he would only need to light the smoke to notify all the nearby tribes, so that they could form a huge team to act together at the same time.

"Boss Shang, why do you have time to come down in person today?" There was some surprise in Old Man Li's tone.

Shang Dong'er went downstairs alone, and did not call Fu Mei to accompany her, nor did she plan to tell her sister about her speculation about Zhang Heng, although the two are sisters, they have different life trajectories, after their parents divorced, one lived with his father and the other with his mother, so the surname is different, Fu Mei followed her mother's surname, and her real name should be "Shang".

"Elder Li, I came to ask why you looked at Zhang Heng differently in the first place?" Shang Dong'er asked directly.

Old man Li was stunned for a moment, in fact, this was also the question he guessed, and after a while, he asked rhetorically: "You also found out?" ”

"What did you find?" Shang Dong'er asked suspiciously.

"Didn't you notice that Zhang Heng had the breath of licking blood from the knife edge......
