The annual Autumn Fair is the most important business exchange event in the Kokura industry. During the fair, there are exercises, elixirs, pets, magic weapons, precious materials, and of course, there are many rare ingredients. In recent years, the trade fair has become more and more prosperous, and the booth rent has risen with the tide, and most of the booths will be rented by strong bulk customers and group customers, such as chambers of commerce and sects.

Ten third-grade spirit stones can be exchanged for one booth.

High-grade spirit stones are exchanged for low-level spirit stones, and the official guide price is 1:100 for each grade. That is to say: 1 third-grade spirit stone = 100 second-grade spirit stones = 10,000 first-grade spirit stones. However, because high-grade spirit stones are more widely used and produce less, their actual exchange ratio is often higher than the official price. Spiritual stones of more than five grades are stored as strategic materials and are almost not circulated in the market.

The spirit stones needed to purchase the booth were an astronomical amount for a low-level monk.

Fortunately, in addition to the official booths, free trade zones are usually derived from the vicinity of trade fairs.

The biggest feature of the free trade zone is that it ...... Freely!

Anyone and any item can be sold, no matter how high the cultivation is, no matter whether the thing sold is valuable or not, and no matter how outrageous the asking price is, as long as the stall is set up in the free trade zone, it is protected by the organizer. Of course, the organizer will charge a fee, and the protection cannot be free.

There will be some messy things on the monk's body, and some of them even the seller does not know the origin, if the eyes are bright enough and the patience is good enough, it is entirely possible to find a treasure in the mass of trading goods.

At the last trade fair, Tang Chen once found a large piece of green turtle shell.

The green turtle shell can be used for refining, and the complete green turtle shell is a good material for refining defensive magic weapons, and the defense is extremely strong. But the biggest value of the green turtle shell is not actually refining, but cooking, take a small amount of green turtle shell into the soup, will make the taste of the soup greatly improved, highly respected by the old food, because the green turtle is very rare, it is not easy to start, the price of the green turtle shell has always been high. That turtle shell was worth at least five third-grade spirit stones at the market price, but unfortunately the seller didn't know the goods, so Tang Chen took it for ten first-grade spirit stones.

In the following months, the frequency of use of soup pots in Qiankun bags skyrocketed.

Last year took a big advantage, and Tang Chen is looking forward to this year's trading fair.

"Qixia Mountain, September 10...... Three months should be in time!"

Tang Chen calculated his schedule and traveled from the Dadong Mountain Range to Qixia Mountain, even if he didn't sit in the teleportation array, there would be more than enough time. The foodie soon fell into longing, fantasizing that he had a sharp eye, and found a few rare ingredients, and the foodie was surrounded by a full sense of happiness.

Yin Gui broadcast a few more local news, and then broadcast the Shattered Star Realm battle report.

Tang Chen closed Yingui, today's news is all about it, and if you listen to it, it will be broadcast in a loop. Although Yin Gui was extremely slow to consume spirit stones, Tang Chen had no interest in listening to the news repeatedly.

He likes Oto-kyu very much, and often wanders in the field, and Oin-kyu is his main channel for obtaining external information.

Yingui first appeared a hundred years ago, the first used for long-distance communication between the army, after a hundred years of development, the technology has been quite mature, began to realize industrialization in the people. Each monk has a sound station, and through a large transmission array, the sound wave signal is transmitted to each station in the area, and then the small transmission array of the station is transmitted to the user, so as to achieve directional transmission of information in the circle.

The company mainly relies on users to purchase the service to survive.

If you want to listen to the announcement, you can go to the station to purchase the station and services, and the station will install a receiving circle for the paying user's tone. The receiving circle contains specific unlock information, which cooperates with the sound wave transmission circle of the sound channel, and after the circle is damaged, the broadcast content cannot be heard, so you can only pay for it again.

The sonic transmission circle is adjusted every year, so the service of the sound gate is also sold on an annual basis.

The principle of the receiving array of Yin Guitai is not complicated, and the Jindan period cultivation is completely capable of cracking it. However, the Jindan monk first respects his identity, and the fee at Yingui Station is not high, so there is no pressure on the Qi Refining Monk to bear the cost, and basically no one will bother to crack the receiving circle.

Oto-kyu service requires a cost, and you have to leave someone else to live.

The time was approaching, and Tang Chen opened his eyes suddenly.

He heard a "rustle" sound.

Look around trying to find the source of the sound, but it's everywhere and it's hard to locate. The sound became louder and louder, like thousands of silkworms gnawing at mulberry leaves together, each sound seemed to gnaw at Tang Chen's heart, making his face more and more ugly, and there was an illusion that the earth was trembling slightly under his feet.

Wait, not a delusion!

The land is indeed moving, and the magnitude is becoming more and more apparent.

Tang Chen stood up suddenly.

In the short time of Leng Shen, the volume has almost caught up with the boiling water, and it is still the kind of whistle kettle.

What's even more terrifying is that the layer of rotten leaves under Tang Chen's feet turned even more violently, making it difficult for him to stabilize his body!

Tang Chen didn't dare to delay any longer, rushed to the nearest big tree, and climbed up with a few swishs. For a grassroots foodie who mainly relies on hunting for food, tree climbing is a must-have skill.

Another advantage of foodies: versatility.

By the time Tang Chen sat on a thick branch, the uninvited guests in the ground had already emerged.

Small black things came out of the rotting leaf layer, and by the light of the fire and the moonlight, Tang Chen could barely distinguish that they were beetles, all black, about the size of an adult's fist. The rustling sound I heard just now was made by the mouthparts of the black beetle, and the cries of countless black beetles converged together, and the weevils blew the trumpet of the charge, which was deafening.

The earth turned into wormholes, and countless black beetles crawled out of their holes.

As far as the eye could see, the entire forest floor was shaking, and the ground was soon occupied by all of them, and there were still dense black beetles gushing out of the cave mouth like a tide, seemingly never-ending.

"Damn it!"

In the face of this overwhelming insect tide, Tang Chen swallowed hard, and his legs became weak.

The campfire had been overturned by insects that had emerged from the ground, and the black beetle did not seem to be too afraid of fire, and the burning firewood was covered by the black beetle's body, which was quickly extinguished due to the lack of air, leaving only wisps of green smoke.

Before the firelight completely disappeared, Tang Chen saw some black beetles climb up a piece of bluestone, crawling all over the complete grass rabbit skeleton. After just a few breaths, the swarm dispersed, and there was nothing left where the rabbit bones had been placed.

Tang Chen felt a chill, these black beetles were so ferocious!

The black beetles moved like a black wave sweeping through everything.

Tang Chen, who was sitting on the tree, felt like a small sampan, floating in the stormy wind, weak and helpless. When Tang Chen found that a large number of black beetles were surrounding the big tree where he was, and when the vanguard began to climb the tree, he almost didn't spew out a mouthful of old blood.

Without thinking much about it, Tang Chen quickly moved towards the top of the tree.

Climb to a height of more than ten meters before daring to take a break and observe the surrounding situation.

In the nearby trees, there were no black beetles gathering and climbing.

Obviously, Tang Chen was targeted, and these insects must have some way to sense their prey.

Not afraid of fire, extremely devouring, able to climb trees, strong perception and surprisingly numerous......

Tang Chen felt that these bugs were disgustingly strong.

He soon discovered that he had underestimated the black beetles.

It's not disgusting, it's perverted!

The trunk of the tree was already crawling with black beetles, and a black wave was heading from the bottom to the top of the tree, not fast, but the direction was clear enough, and in the process, the big tree elephant was dyed black by them. Some of the black beetles that had been squeezed into the lower branches squeaked in a hurry, and then the carapace on their backs parted, revealing a pair of wings and began to fly towards the upper branches.

Black beetles can fly!
