After hearing this, Lin Feng's face immediately fell. Carrido looked funny, patted Lin Feng's shoulder comfortingly, and then left. After a while, Carrido turned back again, but he had a small bag in his hand.

Carrido handed the bag in his hand to Lin Feng and asked him to open it, Lin Feng opened it for some reason, and there were more than twenty shiny crystals inside, red, blue, and green mixed together, and the light that reflected each other made people feel instinctive desire.

Carrido said at this time: "This is the magic crystal, these are all I have accumulated before, now you can use them." ”

Lin Feng was a little overwhelmed, and he wanted to say something but didn't say it.

Carrido said, "Don't worry about it, you are my personal disciple, and these things will also belong to you in the future, and now it is just a little earlier for you," and then turned and left.

Lin Feng seemed to faintly hear his sigh behind him, "I won't need them anyway." Lin Feng couldn't help but think that his teacher might have tried countless methods, but he was still stuck at the peak of the fifteenth level and couldn't break through, had he already given up? Gripping the bag in his hand, Lin Feng secretly swore, "I won't admit defeat like this, I not only have to break through my own bottleneck, but I also have to find a way to make the teacher break through!"

Lin Feng, who was full of thoughts, ended today's potion production early, returned to his small courtyard, and told Shui Rou not to disturb him, and began to meditate. After Lin Feng meditated for two hours, he felt that his mood had finally calmed down, so he took out the small bag given by the teacher, took out a few magic crystals, and looked at them carefully.

The magic crystal is crystal clear, different colors represent different elemental attributes, red is the fire element crystal, blue is the water element crystal, green is the wood element crystal, yellow is the earth element crystal, these four are also the most common magic crystals. For example, the wind element and the thunder element rarely have elemental crystals, which are rare treasures.

The excellence of the magic crystals is distinguished according to the turbidity inside them, the opaque ones belong to the inferior grade, and the translucent ones belong to the medium grade, and the magic crystals in Lin Feng's hand have a high transmittance, indicating that they are all high-grade grades.

Because absorbing crystals of the same attribute would have the effect of getting twice the result with half the effort, Lin Feng left a red magic crystal and put away the others. Lin Feng picked up this crystal, held it in his hand, and once again ran the Junior Mage Meditation Method, and with the guidance of his spiritual power, the fire element in the crystal poured into his mind like a forest, and then quickly transformed into his magic power.

In a burst of excitement, as if a long time had passed, and as if he had only blinked his eyes, Lin Feng's magic power suddenly soared, surging onto the shore like a tide. He felt that his bottleneck had finally been broken, and now he was a first-level junior mage.

After the excitement, looking at the magic crystal in his hand that had exhausted his magic power, it had already shattered into foam. Lin Feng took out an empty potion bottle and collected the powder as a souvenir. This is a testimony to both his successful breakthrough to the full-fledged mage and to his teacher, who expects more from Kali than he does.

Day and night, half a year has passed in the blink of an eye, and it has been a full year since Lin Feng arrived in the imperial capital, and he also spent his sixteenth birthday here.

Because of the help of the magic crystal given by Carrido, during this period, Lin Feng was successfully promoted to a fifth-level junior mage, and his upgrade speed also caused a certain sensation in the Imperial Capital Magic Academy.

However, after learning that Lin Feng relied on the magic crystal pile, in addition to envying his mentor's generosity, everyone's attention to him personally decreased a lot. This also saved Lin Feng a lot of trouble, well, he didn't have to deal with the trouble of buying and buying all kinds of people.

During this period, Nanlin Island also came to the messenger several times, basically his mother's greetings and advice, and the words were full of warmth and care. Lin Feng's uncle Lin Shan also sent a letter, and it was just an official word to reassure him about the territory, perhaps, his uncle hoped that he would never go back.

Previously, Lin Feng arranged for Locklan to collect news and intelligence from all over the country, and now there has been great progress. Although Locklan eats and drinks with people every day, and occasionally takes on a few adventure missions, it seems that there is nothing serious. But in this way, Lin Feng also analyzed from the various gossip they sent: the southern territory of the empire was unstable, and there was a danger of war.

Although Nanlin Island is isolated overseas, and ordinary small-scale wars cannot affect it, Lin Feng keenly feels that if a big war really breaks out in the southern part of the mainland, it will be an opportunity for the development of Nanlin Island. In addition, he was accustomed to fighting and killing in his previous life, and his heart was also restless.

However, before returning to the territory, Lin Feng still had one more thing to do, he had to improve and prepare a potion. Lin Feng was inspired by the physical strength potion used by the war officer, and he wanted to improve the disadvantages of this potion that ordinary people could not use, so that it could be used to improve the physical fitness of ordinary people and improve the physical fitness of ordinary people.

This is also what Lin Feng wants to do for his mother, his mother's illness is because he hurt the origin of his body after great sorrow, and he didn't bother to find a high-level healing practitioner to regulate his body, but as a result, his body collapsed after a year.

Due to the strong effect of the physical strength potion, only the physical fitness of professionals can accept it, and ordinary people can only drink it, and it will only let the powerful energy contained in the potion, tear their bodies. Lin Feng's idea was to improve the energy burst method of the physical strength elixir, so that it could overflow energy more gently and slowly, so that ordinary people's physical bodies could accept and absorb it.

Although Carrido also had the common problem of professionals looking down on civilians, he still gave Lin Feng a lot of help to this research, not only providing a lot of raw materials, but also putting forward some key opinions on the improvement of potions many times, so that Lin Feng successfully perfected his improvement ideas.

Today was an important day, at least for Lin Feng, the physical strength potion he had improved had already been dispensed with. Now there is only one last step, giving it to ordinary people to drink and observing its efficacy and possible adverse reactions. To this end, Carrido used his connections to get several death row inmates from death row to experiment.

Lin Feng didn't have any special feelings, he was not that kind of holy father-type character, and he directly asked his assistant to pour medicine into the death row inmates. The experiment was very successful, at least it didn't kill anyone, although the facial features of those death row inmates were displaced and their muscles were swollen by the soaring potion energy, but the ugly ones were always much more ugly than the dead ones.
