The clear blue sky is like a huge piece of blue paper, and those thin white clouds, slowly floating with the wind, are mixed between the huge blue paper, adding a bit of color to the sky.

Since Xia Dexin had previously said that all the rewards for the freshman assessment needed to be collected within ten days, Chen Huai and the five of them went to various places to receive the Youxue Lotus Pill, the Spiritual Cultivation Time Card, the Fengxing Pill and the Strength Enhancement Pill.

Then he went to the treasure house of Yanming Academy and received a four-grade material for each of them, which was used to improve or advance to the martial soul.

Luo Tai's family is in the ceramics business, and his family background is relatively ordinary. There were no excellent exercises to practice at home, so he chose to receive the academy exercises, and after receiving the elixir and other rewards, he acted separately from Chen Huai and the others.

Chen Huai went to the Library Pavilion that day to explore, but did not find the exercises of the thunder and fire dual system, so he naturally chose to receive the four-grade materials as a reward.

So Chen Huai, He Ningqiu, Chen Xiaoxiao, and Wei Ling'er went to the material library of Yanming Academy.

At the door of the academy's treasure house, there was a middle-aged man, dressed in a simple gray cloth robe, tall, with big shoulders and a round waist, standing there gave people the feeling of standing like a mountain.

Chen Huai and a few people stepped forward, explained their intentions to the middle-aged man, and handed over their respective student certificates to the middle-aged man and said: "Hello teacher, we are the champion group of the freshman competition, and we are here to receive our reward, this is our college certificate. ”

The middle-aged man took the student certificate, checked it with the information, and then returned the certificate to Chen Huai and the others, and said, "Okay, let me explain in advance, there are all kinds of dangerous enchantments in the treasure house, remember not to run around." The fourth-grade materials and the third-grade materials are stored on the second floor, and you can pass through the barrier on the second floor by taking this jade piece. ”

The middle-aged man said, took out four small red jade pieces, handed them to Chen Huai and the others, and then said: "The materials in the treasure house have spiritual power marks, after choosing a fourth-order material, put the materials and jade pieces together before you can bring them out, and then give them to me to check and register." Let's go inside. ”

Chen Huai and the others immediately nodded in response, and walked into this treasure house.

After entering the treasure house, there was a huge room in front, the whole room was shrouded in yellow light screens, and there was a mahogany staircase in the area on the right hand side of the room that was not covered by the light screen, and Chen Huai and the others immediately climbed the stairs to the second floor.

The room on the second floor of the treasure house is also covered by a strange light screen, but the color of the light screen on the second floor is different from that on the first floor, and the color of the light screen is red, which is the same as the jade piece in the hands of Chen Huai and others.

Chen Huai and the others came to the door of this room, that is, in front of the light screen, and according to what the middle-aged man said before, they picked up the red jade piece in their hands and faced the light screen in front of them that was full of powerful spiritual power fluctuations.

As the red jade approached, the light screen floated slightly, and then spread out like water waves, creating an area nearly two meters high, and Chen Huai immediately held the red jade in his hand, passed through the vacant area, and entered the interior of the room.

After Chen Huai entered, the light screen immediately returned to its original state, and the rest of He Ningqiu and the others, using red jade tablets, changed the shape of the light screen, and entered the treasure house one after another.

As soon as they entered this room, everyone was shocked by the sight in front of them, the treasure trove room was very large, and there were rows of shelves made of fine black gilt jade, and tens of thousands of spiritual materials were stored on the shelves.

Chen Huai was stunned by everything in front of him, regardless of the thousands of spiritual materials, just this black gilt jade shelf that presented spiritual materials was a valuable spiritual material.

This black gilt jade is a three-grade material, which can exude a soft spiritual power aura, store and protect spiritual grass, spiritual materials and other items, and is generally made into a box and other sizes to preserve precious items. Like Yanming Academy, it is made into rows of shelves, but I have never heard of it, so I can see the rich heritage of Yanming Academy.

The rows of black gilt jade shelves erected, although they are not like boxes and cabinets that completely seal the spirit grass and spiritual materials, but the volume of this black gilt jade frame is huge, and its spiritual power and aura are gathered together, which is enough to protect these spirit grasses and spiritual materials.

Chen Huai and the others found that these spiritual grasses and spiritual materials were not placed at random, and these materials were classified in detail according to their attributes and characteristics, which was quite convenient for everyone to find suitable materials for themselves.

The four of them immediately dispersed and walked towards the black gilt jade frame that matched their attributes. Chen Huai did not go to the black gilt jade shelf where the thunder-based materials were stored with Chen Xiaoxiao, but walked straight to the shelf where the fire-based materials were placed.

Chen Huai's idea is this, the selected spirit grass and spirit materials are used to improve his own martial soul level, and his thunder beast martial soul is an innate heaven-level martial soul, and it may be difficult to improve it again, and it is definitely not possible to do it with this mere four-grade material.

Therefore, it is better to choose a fire-based material, and first improve your own ground-level martial soul Flame Spear, which is easier to improve than a heaven-level martial soul.

Although Chen Huai does not use the Yan Xingyan Spear now, the improvement of his martial soul level is also of great help to his users themselves. If the Yan Xingyan Spear can successfully improve the rank, it may enhance Chen Huai's combat effectiveness a lot.

Chen Huai walked among these tall black jade shelves, feeling the rich and soft spiritual power of the black gilt jade, and looking at the various spiritual grasses and spiritual materials on the shelves.

Flame vine scales

Burnt grass

Bloodflame Steel

Fire Spirit Teeth

Chen Huai shuttled between the shelves full of fire-based materials, running the spirit control technique, controlling the spiritual power to feel and look at these materials full of fire-based spiritual power, if he encountered a suitable spiritual grass or spiritual material, Chen Huai would take it down and carefully inspect it to see if the quality and function of the material were feasible.

After a while, Chen Huai put the four-grade spiritual material in his hand, the Yan Muscle Bamboo, back on the black gilt jade shelf, wrote down the location of the Yan Muscle Bamboo in his mind, and then walked towards the shelf.

The quality of this Flame Muscle Bamboo is very good, the material is extremely tough, and it also contains a large amount of fire-based spiritual power, Chen Huai guessed that if this Flame Muscle Bamboo is refined, it can not only improve his spiritual power, but also make the Yan Xing Flame Spear harder and more resilient.

Although this Yanjian Bamboo is already a good choice, Chen Huai still wants to explore all the shelves of this fire-based material, and then decide the material he wants to choose. In addition to this Yanjian bamboo, Chen Huai also took a fancy to two materials before.

After a while, Chen Huai checked all the black gilt jade shelves where the fire-based materials were placed, recalled the four materials he was optimistic about before, compared the advantages and disadvantages of the four materials, and then determined the materials he wanted to choose, and walked straight to the materials.

Just when Chen Huai passed by a black gilt jade shelf, he suddenly felt that something was wrong, and Chen Huai's spiritual power told him that this shelf seemed to be a little different from when he was exploring it just now.

Something seems to have changed on this shelf?
