Waiting for Qinghe, Xiuyuan and Xuanrui returned to their residence from the inner courtyard, and when they saw what Yang Sheng tossed out, several people came over.

"What are these?"

Yang Sheng made three such telescopes in a day's work, and said, "Xuan Rui, you can already use the killing technique of sword cultivation, you can try to cooperate with this object and use the killing technique." ”

Xuan Rui wore the hoop goggles, adjusted it for a while, and then performed the killing trick, he can already kill the weapon as a knife repairer, but it is not yet able to meet the entry requirements of cutting hundreds of zhang after the knife, at most twenty zhang distance can be controlled accurately, beyond this distance, the accuracy will be far worse, and the control of the knife will be greatly weakened. Proves that there is still a long way to go.

Yang Sheng noticed that Xuan Rui threw a pill of Lingqi Stone on his Feimiao Knife, and in his Feimiao Knife was a white spirit spirit, which was a group of white qi in the vein of Shushan Wawu, in the land of spiritual veins, coupled with the continuation of generations of ethnic groups, this vein group has a lot of spiritual power, and some of them are much beyond their own age, and they have lived past one hundred and fifty or sixty years old and become the elders of the group. And 貊 is a kind of body pattern, the best at predatory beasts, than the tiger is not much more worried, in the original Wawu vein mountain, and the next peak of the bear group do not deal with each other, often compete with each other for territory. However, although these spirits prey on wild beasts, they do not set foot in the places where they practice Qi practitioners, and they do not harm people's lives, which can be regarded as a kind of balance. And after the death of these spirits who already have the power of spirit, they can use the spirit for the disciples of Shushan to integrate into the spirit soldiers.

It's also a balance.

After the robbery of Shushan, the Wawu vein was difficult to survive alone, and this group was also wiped out, and some of the spirits were accepted by the spirit soldiers of Shushan, and the spiritual weapons that can be used by disciples in the Shushan Sect are now achieved.

Xuan Rui's knife is a white spirit, belonging to the elders of the original group, the best at concealment, the speed and explosive power are extremely fast, and even can catch birds, so the spirit soldiers with the spirit of the spirit have supplied Wang Cunyuan's Feiyan Gong line. And it can be seen that Wang Cunyuan has high expectations for Xuan Rui, and the white spirit of the knife for Xuan Rui is also the strong king of the original group.

Xuan Rui put on the eyepieces, made a move, the knife flew out, slashed a tree in the distance, cut off the ancient tree with a circumference surrounded by a person, and flew back, Xuan Rui sat on the ground with his buttocks, and did not react for a long time.

Yang Sheng knew at a glance that this was a manifestation of excessive mental consumption, because the distance that the knife flew over just now was already nearly a hundred zhang!

"It works!" Xuan Rui looked up at Yang Sheng in a daze after a while, his eyes were still a little sloppy, "It's like drinking a big sip of spicy throat wine...... It's so delicious!"

......

Xuan Rui slowed down for a long time before he came back to his senses, and the increase in vision brought by the telescope greatly increased the distance of his imperial weapon, knowing that his previous effective range could only hit objects twenty zhang away. Now, in an instant, it was as if he had crossed the boundary that required months or even years of hard practice, and he had almost reached the point of getting started with sword cultivation.

It's incredible.

"It's simply ...... Yang Sheng, how did you do that?"

"What kind of artifact is this?"

Seeing the surprised expressions of the three of them, Yang Sheng knew that now was a trembling burden, so that his friends admired him to the point of no more, but he still couldn't get past his own level, mainly because he couldn't face this face of curiosity.

"In fact, it is a simple truth, the principle of refraction, reflection and imaging of light, light can be refracted and reflected by the medium, just like a mirror and this crystal lens......"

Yang Sheng took the two lenses and explained the whole principle to them like a lecture, and the three of them blinked their eyes.

"How did you come up with that?"

"Let's just say you have a lot of ideas......"

"You seem to be better suited to the ...... of tricks."

Trap ...... I wonder if I can make a steam engine...... But to make a steam engine, is this going to take the hardcore style of steam cultivation immortals?

Seeing the surprise expressions of Qinghe Xuanrui and Xiuyuan mixed with "can you still be like this!" in their sudden realization, Yang Sheng felt that it was not bad to be a teacher who surprised the students without fooling them like a magic stick.

"It's a pity that I can't use the weapon, otherwise I'll have to try this wonderful feeling," Xiuyuan looked at the monocular and was stunned, "There is no way to use this on the talisman seal...... However, this can magnify objects out of thin air, and in many places, it can be very useful. ”

"However, for our high-ranking cultivators in Shushan, it doesn't mean much. Because he has become a high-level cultivator, or even a great cultivator, his eyesight is far from being comparable to that of a middle-level and lower-level alchemist, just like the sword of instrument cultivation, and the high-level instrument cultivation can produce a sword of thousands of zhang, which also means that it can lock things beyond thousands of zhang, this ...... Binoculars are useless. ”

Yang Sheng thought in his heart that if he wanted to see so far, he could still do it, but it would be difficult to say that he was against others and locked on to the other party.

"Next, we're going to promote this thing...... Do you think the disciples in the peak are willing to buy it, and how much will it cost to buy it?"

Xuan Rui said, "I think I must be able to sell it! If it were me, for the sake of my promotion just now, I might be willing to spend fifty pills, which is almost my previous month's income from the outer door chores, to feel the pleasure of this kind of cultivation by leaps and bounds! As for the inner door instrument cultivation, they are all rich, so they are even more willing to spend money." After all, it can increase the distance of their imperial weapons. ”

Yang Sheng said to the three of them, "Tomorrow we will divide our labor, Xuan Rui, you are responsible for contacting the instrument cultivation disciples of the four courtyards, Qinghe, you are in charge of the instrument cultivation senior sister of the inner gate, Xiuyuan, you go and ask the male disciples of the inner door instrument cultivation...... Each of you takes a finished piece, pays for it if you need it, writes down the list, and then gives them the finished piece in a few days. ”

Of course, Yang Sheng got the money first, and then went to Song Ziyuan to make it according to the list, of course he wouldn't let the goods smash into his hands first, and give the money to place an order first.

"I'm going to ask too?" Xiu Yuan's face was embarrassed, he wasn't good at this kind of peddling after all.

For the cultivation of the gentleman's style, this kind of thing is no less than hiding under the overpass and asking people if they want a piece, or if there are any incurable diseases that need to be treated...... Yang Sheng thought for a moment, nodded with a smile on the corner of his mouth, "In that case, you don't have to ask, you are responsible for writing ......"

"Write ......?" Xiu Yuan looked at suspiciously.

"You go get a piece of paper to ......"

Xiu Yuan ran to get the paper, and picked up the pen again, with a pair of talismans and seals, everyone was ready to write.

"I'll read what you wrote. ”

Yang Sheng said, "Have you been depressed all day long because the bottleneck of instrument cultivation cannot be broken, and have you sighed because the gap between the imperial weapon and others is the difference between victory and defeat?

Are you willing to be a step behind? Are you willing to be left behind? Are you willing to only look up at the scenery on the peak of cultivation and not be able to appreciate it?

Now, here comes your savior...... Horizon Weapon!

It can allow you to gain a larger field of vision, obtain more precise control, and obtain the most critical life and death level of weapon cultivation - shoot farther than others!"

After Yang Sheng finished speaking, Qinghe and Xuan Rui looked at him, their eyes blinking.

Xiu Yuan held the pen and looked down at what he had just written, and a sense of shame came to his mind.
