Thinking that "friction and electricity" could inspire the old man, Lu Chen planned to write down some of his understanding of water on earth before leaving, and then attach some fantasy applications about water from games and novels. He hoped that the old man could get something from it, and advance to the ninth level he had always wanted to reach, and then walk out of the closed magic tower.

At this time, Lu Chen realized that it was no longer in the restaurant. There was a huge transparent crystal cover on the top, which could directly see the starry sky at night. It was surrounded by a half-person-high wall. The forest scenery could be seen at all, but it was night now and the view was not wide. There was no partition on the entire floor, just a huge room.

"This is probably the best star-watching platform."

Looking at other decorations, it is like a combination of a study, bedroom, and laboratory. There may be various records to be made, and several thick stacks of paper are piled on a huge desk.

Lu Chen did not waste time studying the difference between paper and pen and the earth, nor did he care whether the words he wrote could be understood by the old man. He just wrote some basic common sense and concepts in his memory on blank paper based on his feelings. In a hurry, he did not realize that what he wrote was different from Chinese characters.

———————————————————————————————

The old man came back about an hour later. When he saw Lu Chen lying in front of his workbench, Cisco was recording something, he did not interrupt him, but just walked gently behind him. At the same time, he also remembered that he had a letter of introduction to write.

But at this glance, the old man's eyes were inseparable, which was obviously part of the application of water. What made him most fucked was "What would happen if he controlled a small water ball to trap someone's head, or what would happen if he immediately turned into an ice hockey after the head was trapped."

Another idea that was extended next was even more stuttering. "If we could immediately freeze the water-based spells, will spells such as vortex and water tornadoes have centrifugal force spray ice cubes or even ice cones around?"

The former one seemed very simple, but the old man knew that the requirements for manipulation were very high, and no one would stand there stupidly and let you put the water ball on your head. This is also the reason why all mages are habitually ignored; but the latter one is relatively simple, and it is very easy to imagine that just apply a freezing technique to the vortex technique released by himself. Although he did not understand what centrifugal force was.

The old man knew very well the power of magic such as vortex and water tornado, which was to kill the enemy by rotating power. It can be imagined how strong it would be if the ice cone was thrown out. Even the broken ice cubes were enough to kill people with low strength. Releasing it on the battlefield is absolutely deadly, and its power can be increased by at least one level.

Come back to his imagination, the old man did not disturb Lu Chen. He knew that it was what Lu Chen was going to leave for him, and he was not in a hurry. At this moment, he quietly walked aside and wrote a letter to let Lu Chen bring to his vice president and student. He was also one of Lu Chen's senior brothers. Of course, the content was a little more than before. In addition to asking them to take good care of Lu Chen, the junior brother, he also asked them to get closer to him and ask him humbly. Before he grows up, don't disclose his identity, so as not to cause necessary trouble, etc.

Time, another hour passed, and the old man had already finished writing the letter. Seeing that Lu Chen was still thinking attentively, he had no intention of stopping, so he could only walk over and interrupt him.

"Little Lu Chen, it's enough, no need to think about it anymore. Your 'friction and electricity' plus these are enough for me, an old man, to study it even if I go to the underworld. I don't have much time left, and I still have some things to tell you."

"Ah, teacher, you are here. Is it that fast? Isn't it three hours? But I can't think of anything." Lu Chen rubbed his temples and said a little disbelief.

"Haha, it's been more than two hours. Come on, come over and stretch out your hand. You don't have magic. I'll help you contract the space ring."

Only then did Lu Chen realize that the space ring that was originally worn on his hand had returned to the old man's hand. Combined with the old man's words, he understood that the luggage that the teacher packed for him was all in the space ring.

"This, teacher, you gave it to me, what do you use?" Lu Chen did want it, but he was embarrassed. Besides, the teacher is a Dharma Saint, and the space ring he used must be a very rare and precious item.

Lu Chen's reaction made the old man's favor again. He was indeed a little reluctant to part with this space ring. Although it was not infinite space, it was also ridiculously large. There was no big problem with installing this magic tower. However, at his current level, the space ring was no longer effective.

A few potions and foods, even if they add some daily necessities and spare equipment, cannot use one of them. They are not an alchemist, a scrollman, or something, and do not need to carry a lot of materials. Magic experiments are basically done in the magic tower. This huge space is more of a commemoration for him. Now it is a good choice to give it to this magical student as a gift.

"Does the teacher still have to worry about you? You forgot Moxili's unlucky space ring, but you can't use his. By the way, you have said before that you want to be a archer. The equipment of the assassin is just right for you. I moved all the equipment in his space ring here. It's a pity that the set he wore was chopped into pieces by lightning; but some of the other spare items inside are also good treasures, that is, be careful when you use it in the future, and don't be seen."

"Well, I know, thank you teacher." After the old man said this, Lu Chen happily accepted the teacher's space ring, and he also understood how dangerous it was to be recognized with the enemy's equipment.

After helping Lu Chen to use the space ring contract and teaching him how to use it, the old man repeatedly reminded Lu Chen when he was in danger, and then continued: "There are some scrolls in it for you to defend yourself. However, the teacher is not a scroll master. None of them is powerful. Most of them are third- and fourth-level magic, which are accumulated when teaching the first few students. The color and the number of stars represent attributes and levels, and then the name. Take the time to take a look. Don't be busy when you encounter danger. Be sure to use it proficiently before becoming stronger."

"Well. Teacher, don't you really leave this magical scepter?" The old man's concern made Lu Chen feel urged to say the power of the magical scepter, but considering that he could not explain it, he could not operate the magical scepter, fortunately he didn't say it in the end.

"No, the knowledge you left me is enough for me to think. After this time, I have no confidence to save the artifact, and the Kingdom will keep it. I have already stated this in the letter. Don't you have to worry. Now no one knows that the artifact is not in my hands, and no one will regard you as a target; and maybe you can also use other people's hands to open this magic tower as soon as possible. How can I say that this tower is the best in the Kingdom? It's really a waste to just seal it up and use it for me alone, haha."

The old man was not worried at all that he would be trapped in the magic tower. With the things that Lu Chen left for him, he was confident that he would unlock the closed magic tower after breaking through.

"Let's go, I'll send you out now. Twelve hours is just the maximum time limit. The longer you delay, the more uncertain it is." After saying that, the old man took the lead in walking towards the middle of this floor.

Lu Chen also felt that there was no need to say anything else and followed the old man.

———————————————————————————————

There was a very obvious magic circle on the ground, which looked extremely huge, but the small circle in the middle was only enough for one person to stand.

After Lu Chen stood up, the old man recited a spell and activated the magic circle.

Although he didn't understand magic, looking at the old man's chanting time and the range of the magic circle, Lu Chen knew that it would be more difficult than he thought to get out of the magic tower.

A sourness in my heart for no reason, and I felt like I was going to be farewell to this teacher who had only known each other for a day. The powerlessness and regret that could not save the girl in my dream was also drawn out.

As if he was swearing, Lu Chen shouted at the old man standing outside the magic circle: "Teacher, I will definitely study hard and become strong as soon as possible to come back to see you."

The old man heard what Lu Chen meant, shook his hand, signaling him not to care, and then smiled and stretched out three fingers, and made a gesture that he would go to find him.

It wouldn't be three months, and it wouldn't be three days. Lu Chen easily understood what the old man meant. The sadness of parting in his heart faded a lot, and then disappeared as the magic circle lit up.

———————————————————————————————

On the edge of the Newcorun Forest, more than a dozen carriages formed a circle, and the bonfire was burning vigorously in the middle. A group of people holding weapons guarded the joints of the carriage in two or three.

"Damn Hill, didn't you say that the edge of this forest is very safe? Why are so many fire mastiff beasts running out now?"

"Captain, you can't blame me for this. The Newcorun Forest is famous for its safety. The strongest one here is the fourth-level fire mastiff beast. God knows why they ran out of the center of the forest, and maybe all of them are here. Look at the dozens of cubs behind the trees there."

"Looking at their appearance, they are just defending themselves, not really trying to fill our stomachs. I heard that this is the private territory of Ron Chicres Fassaurus. Perhaps something happened in the forest, these fire mastiffs had to come to take refuge in the periphery."

"Sharon, what you said is true or false, why haven't I heard of it?"

"Tsk, who made you only interested in money and women? You have never seen you care about things in the kingdom, and you are the captain."

"Hill, you kid want to die. You dare to say this to me in front of Sharon. I won't pull your skin after seeing you back."

"Okay, stop arguing. Sharon is right. Everyone cheered up. They are all night monsters and have lost a lot. As long as we can hold on until dawn, it should be fine."

"Yes, the leader."

"Really, the leader?"

"Hesgau, you are a 'warzone' with only brute force. When you go back, you can learn something for me, otherwise I will withdraw your captain and replace it with Hill."

"Haha, thank you, leader."

“…Yes, the leader.”

"Note that they are going to attack again, everyone is ready."

"Hehe, Sharon is so good. You can see that. Should you consider joining us after you go back? Our group still lacks a deputy leader."
