Yu Tianlai listened to the old man who grinded the mirror and really recognized the origin of this ancient mirror, and couldn't help but be quite surprised, and immediately invited him to the room to talk in detail.

After sitting down, the old man pointed to the ancient mirror on the table and said: "The little old man has been obsessed with bronze mirrors all his life, and he has a lot of knowledge in various mirror-making techniques in ancient and modern times. The 'kaleidoscope' little old man has only seen some records of scales and claws in some ancient books, but he has never been lucky enough to see the real thing. ”

Yu Tianlai asked: "What is the mystery of the 'kaleidoscope' that the old man said?"

The old man who grinds the mirror said with these leisurely expressions: "Legend has it that the 'kaleidoscope' can ingest the external influence into the mirror, and then project it into the void. Xiao Lao'er originally thought that this legend was exaggerated, and it was not until this moment that he finally believed that there was such a strange treasure in the world. ”

Yu Tianlai's eyes were a little straight, and he subconsciously held the ancient mirror in his hand, but he couldn't imagine that this old antique actually had photography and projection functions, and it was also the most advanced three-dimensional projection.

Seeing his incredulous face, the old man who grinded the mirror explained with a smile: "The mystery of the 'kaleidoscope' lies in these pits on its surface. The position, depth, and angle of each pit are calculated with great precision, and if the light source can be set in the appropriate position, the light refracted by the mirror and the pit can be affected. Such a method is really ingenious!"

Nie Yinniang, who was obediently standing beside Yu Tianlai, looked at the ancient mirror in his master's hand, and couldn't help but ask: "Master, you said that this mirror has been passed down for hundreds of years, has no one ever thought of using it to reflect light, see if there will be any discoveries?"

Yu Tianlai pointed to the patina-mottled mirror and shook his head: "This layer of things covered by the mirror seems to be patina, but it is actually another substance. The substance appears to have penetrated into the mirror and cannot be removed at all. ”

Nie Yinniang turned to the old man grinding the mirror and asked, "Does the old man have a way?"

The old man who grinds the mirror arched his hand and said: "If the two of you can trust the little old man, the little old man can try his best." ”

Yu Tianlai handed over the ancient mirror without hesitation: "Please also ask the old man to let go." ”

The old man took the ancient mirror, then opened the box he was carrying, took out some bottles and cans from it and placed them on the table. He asked Nie Yinniang to order someone to bring a large basin of boiling water, and successively picked up three small porcelain bottles and put some medicinal powders of various colors in the water. After the pot of boiling water turned black, he dipped his hands in the water along with the ancient mirror.

While cleaning the ancient mirror, he said to Yu Tianlai and Nie Yinniang: "If the little old man sees it well, this ancient mirror should be smeared with a layer of special cement." It can only be washed off with a special potion, and it just so happens that the little old man knows this prescription. ”

After a long time, the old man who grinded the mirror took out the ancient mirror from the potion, first wiped off the water stains with a clean white cloth, and then took out six or seven brushes of different sizes and shapes, stained with several different medicinal powders, and brushed them several times, and finally polished them carefully with a piece of deerskin, and suddenly shouted with a smile: "Okay!"

Yu Tianlai and Nie Yinniang's master and apprentice stepped forward to watch, and saw that the ancient mirror in the hand of the old man who grinded the mirror was very different from before, and the mirror surface was scorching, and there was no trace of patina.

The old man who grinded the mirror asked Nie Yinniang to send four large bronze mirrors, which were placed in four directions of the room with wooden frames, and a huge candle was lit in front of each bronze mirror. He closed the doors and windows to prevent a ray of light from outside, and then carefully adjusted the angles of the four bronze mirrors, casting four rays of light onto the ancient mirror mirror that lay flat on a table in the middle of the room.

Where the four rays of light converged, the ancient mirror suddenly gave birth to a vision, a hazy yellow light projected from the mirror surface into the void above, and the image of a building gradually emerged within the yellow light. The image faded from blurry to clear, and finally it was a miniature architectural model that resembled a solid entity.

Yu Tianlai's eyes were far sharper than ordinary people's eyes staring at the image in the void, but he saw that it was a small Taoist temple, and even saw clearly the three dusty fonts of "Yellow Bud View" written on the plaque at the main entrance of the Taoist temple. The most bizarre thing is that in that image, there is a building that is more than ten times larger than the Taoist temple itself.

He knew in his heart that most of the legendary Wei Boyang's relics were hidden in the underground palace under the Taoist temple, so he was engrossed in observing and remembering every detail in the image. Thanks to his increasingly powerful psychic powers, his memory has now been greatly strengthened, and in a matter of moments, he has completely reproduced the entire effect in his brain.

Seeing that Yu Tianlai's eyes had moved away from the image in the air, the old man grinding the mirror on the side suddenly moved away from a bronze mirror next to him, and the image in the air disappeared instantly with the change of the light source.

Nie Yinniang complained with some dissatisfaction: "What are you doing, old man, I haven't seen it clearly!"

Yu Tianlai was also a little surprised, he could be sure that the old man who had just sharpened the mirror did not carefully observe the aerial image, could it be that the other party really did not have the slightest interest in the secret hidden in the image?

The old man who grinds the mirror seems to see the doubts in Yu Tianlai's heart, and arches his hand to him: "This gentleman, the little old man has a reluctant request. ”

Yu Tianlai said: "The old man has something to say, please speak." ”

The old man grinding the mirror said: "Sir, the influence in this 'kaleidoscope' must have a great secret, but the little old man has no covetous heart for this, please rest assured." What Xiao Lao'er is interested in is the ancient mirror itself. Therefore, I suddenly implore Mr. that when Mr. can't use this ancient mirror, can he temporarily lend it to the little old man for a period of time?"

Yu Tianlai was stunned for a moment, but when he saw that the other party looked indifferent, he bowed his hand and said: "The old man is so open-minded, I admire it." As for this ancient mirror, it will be given by both hands at that time. ”

The old man who grinds the mirror laughed: "Thank you Mr. for being so young, sir, farewell!"

With that, he packed up his belongings and turned around and sprinkled away.

It turned out that Yu Tianlai only learned about the place of Weizhou from Cang Song's mouth, and now he has a clear clue, and with the help of Nie Feng, the powerful local snake, it is naturally much easier to find it again.

Three days later, a group of people sent out by Nie Feng returned to report that they had found a Taoist temple forty miles away in the eastern suburbs of Weizhou that had been abandoned for many years. After asking the local elders, it was confirmed that the name of this Taoist temple was called "Huangya Temple".
