Lin Zichen looked up at the sky with the Holy Fire Crystal, only to see the sunset in the west, and the mountains slowly covered the afterglow of the sunset.

He nodded, maybe it was the light of the setting sun that inspired the seal of the holy fire crystal, this stone was really not as simple as the Purple Lion Clan's holy relic, there should be another source of this.

Moreover, at the beginning, Lin Zichen in the Seven Holy Mountains clearly felt that the Divine Heavenly Stone had the breath of Dao Xuan Tianzun, obviously the Divine Heaven Stone was very likely to come from another world, so although this Holy Fire Crystal did not have the breath of Dao Xuan, it had a similar aura to the Divine Heavenly Stone......

Lin Zichen immediately deduced that this stone might also have something to do with another world.

As for where that world is, Lin Zichen doesn't know, but ...... It seems that he is starting to feel that he is getting closer and closer to there.

"Master, what's wrong with you?"

It wasn't until Xiaofeng shouted that Lin Zichen came back to his senses: "Huh? Oh, no, nothing, let's go. ”

All the way to the valley where Mona was sealed, Lin Zichen asked Xiaofeng and Chen Weilong to guard the entrance of the cave first, and then walked in with Kaka.

After taking the Pure Yang Pill, Mona's physical condition was significantly better, and although her body was still very thin, she was much plumper than the last time she saw it.

Mona was asleep, and listening to the breath of her breathing, she could hear that it was much smoother, more peaceful than before.

Kaka took the food from Mona's side out of the cave, threw it out of the cave, and immediately lay down beside her mother, and whispered, "Master, can you wait for my mother to wake up naturally?" ”

Looking at the picture in front of him, Lin Zichen couldn't help but feel a sour nose, he smiled and nodded: "Don't worry, if the Holy Fire Crystal can really be unsealed, I will unseal it while it is asleep." ”

Kaka looked at Lin Zichen, his eyes were full of gratitude, and he immediately leaned against his mother's side.

Lin Zichen took a deep breath, no matter what status a child grows to, he may be like a baby by his mother's side, able to snuggle up to his mother's body, and it may also be the time when he feels the most secure.

Immediately, Lin Zichen slowly sacrificed the Holy Fire Crystal, and the transparent stone was suspended in the space, shining with a warm luster.

Lin Zichen looked at the Holy Fire Crystal in silence, trying to sense the power in it, after all, although the Holy Fire Crystal was in his hand, he had never controlled it.

Suddenly, Lin Zichen felt that under the action of True Qi, the power in the Holy Fire Crystal suddenly underwent a subtle change, as if a force was slowly radiating outward, and this power ...... Apparently controllable.

Lin Zichen nodded, his first attempt to manipulate the Holy Fire Crystal was naturally a little unfamiliar, but if the control was successful, he would naturally become proficient after a few times, and he could reach the speed at which Xuan Nai released flames.

He tried to control that power, and sure enough, under Lin Zichen's control, those forces began to react on the Holy Fire Crystal, and the internal and external forces were connected, and soon a new power was formed, and this power was within the Holy Fire Crystal.

Suddenly, Lin Zichen felt that the true qi around the Holy Flame Crystal suddenly began to converge towards a center, as if it was ready to attack, constantly contracting, and finally forming a visible true qi mass.

Lin Zichen's brows furrowed, knowing that this should be a sign that he could manipulate the Holy Fire Crystal, and this True Qi Mass was the support for the power in the Holy Fire Crystal.

Just when he was thinking about how to urge the power of the Holy Fire Crystal, he saw that the True Qi Mass suddenly exploded, forming a powerful force that rushed into the Holy Fire Crystal, and the other end of the Holy Fire Crystal also instantly struck out a True Qi and rushed straight towards Mona.

The moment the True Qi touched Dao Mona, it suddenly became gentle, like a piece of clothing covering the surface of Mona's body, and soon, that visible layer of True Qi slowly dissipated, and finally turned into nothingness.

Lin Zichen narrowed his eyes slightly and looked at Mona, who was still asleep, and didn't seem to have any signs of waking up, but ...... The breath seems to have changed somewhat.

Lin Zichen stepped forward and squatted down to feel the breath in Mona's body, and soon, he nodded: "Sure enough, Kaka, Mona will take it out of the cave after you do, there should be no problem." ”

"Yes, master, that's it...... Unblocked? ”

Lin Zichen smiled: "I'm not familiar with the Holy Fire Crystal, so it's a little difficult to control, but fortunately, the power in it has been stimulated, and the original old aura in Mona's body has also disappeared, if it's good, it's the sealing qi." ”

"Understood, master!"

Then, Lin Zichen walked out of the cave and looked up, it was already late at night, but Xiaofeng and Chen Weilong were still sitting on the other side of the valley.

Seeing Lin Zichen walking out, Xiaofeng hurriedly ran forward: "Master, how is it?" ”

Lin Zichen nodded: "It should be unsealed, but ...... The way this flame crystal is controlled is indeed something special, and I have never encountered it before. ”

Lin Zichen had all the processes that had just been activated by the Holy Fire Crystal, among which the convergence of the True Qi inside and outside the Holy Fire Crystal was a commonly used means of manipulation, and he also used this method to refine the rune stone at the beginning, but it was just ......

Thinking about it, Lin Zichen's eyes seemed to have the ball of true qi behind the Holy Flame Crystal again, which was the most puzzling picture of this kind of urging method.

What kind of power is that true qi? As soon as the true qi exploded, it seemed that all the power poured into the Holy Fire Crystal, thus stimulating the breath in the Holy Fire Crystal.

Just thinking about it, Lin Zichen's eyes suddenly widened: "There is!" ”

"Got it?" Xiaofeng looked puzzled, not knowing what Lin Zichen was talking about.

After Lin Zichen finished speaking, he walked quickly to Chen Weilong and said, "Weilong, if I say what I think, can you draw a drawing?" ”

"Huh? Captain, what kind of drawings are you talking about? Chen Weilong also looked confused and said.

Lin Zichen ignored it, pacing back and forth obviously thinking about something, and with a subtle smile on his face.

Chen Weilong and Xiao Feng glanced at each other, Xiao Feng showed a look of fear, and said, "What's the matter, the master won't ...... Crazy, right? Could that Holy Fire Crystal drive people crazy? ”

"Xiaofeng, don't talk nonsense, the captain should be thinking about things."

"But...... But look at him, what do you think, he's stupid......" Xiaofeng's expression didn't seem to be joking, as if he was really frightened by Lin Zichen's state.

Lin Zichen suddenly turned around: "There is, crossbow!" ”

"Crossbow?" Chen Weilong said.

"Yes, Weilong, I will use the relationship of the academy to find the strongest metal for you, and then build a crossbow, but the crossbow design is different from the tradition, not relying on the catapult power to send arrows, but on explosive power!" Lin Zichen said.

Chen Weilong thought for a while when he heard this: "Crossbow...... I had been in contact with it when I was at the Military Academy, and I knew a little about the construction of crossbows, but the explosiveness was ......."

Lin Zichen smiled: "This explosive power refers to the sudden explosion of a momentum of power, and then let the crossbow arrow shoot, in this way, the launching power of the crossbow arrow has surpassed the ordinary war crossbow, but reached the power of true qi!" ”

"The power of true qi ......" Chen Weilong nodded slowly, "Captain, what you said is right, I can understand it, but how can you have such explosive power?" I can't use my true qi to urge it, in that case, this crossbow is meaningless at all, it is better for me to attack with my bare hands. ”

"Hehe, you're right, but I have a way to make this explosive power appear, set up a true qi slot behind the crossbow arrow, once the true qi in the slot bursts out, the crossbow arrow will naturally be ejected." Lin Zichen said.

Xiao Feng rolled his eyelids: "Captain, Brother Wei Long is asking how to create this kind of accumulation of true qi." ”

Chen Weilong nodded when he heard this.

"Elixir!"

"Pills?" Chen Weilong said.

"That's right, if a pill only contains true qi that can burst out, I can mass-produce this pill, and when the time comes, it will be refined only for you Chen Weilong!"

Hearing this, Chen Weilong took a deep breath, and suddenly an extreme honor came to his heart.

Lin Zichen has always been tall in his eyes, and he can let the captain personally refine an elixir for himself? He didn't even think about it.

And Lin Zichen actually had this idea in the Purple Lion Valley this time, and he was very firm.

He found that Chen Weilong's ability was not only limited to ordinary battles, but also very effective against martial artists and demon beasts, coupled with his own strength in the Mortal Realm, if he could make good use of this True Qi attack weapon, it would definitely be the most powerful output.

"Captain, only ...... Refining for me alone? ”

Lin Zichen nodded and smiled: "Yes, I am confident that this weapon will be the basis for a sniper to gain a foothold in the martial arts!" ”

"Captain, you can say it, as long as you can say it, I can build any kind of structure!" Chen Weilong stood upright, stood in a standard military posture, and said.

Subsequently, Lin Zichen told Chen Weilong about the structure of his imagination, and Chen Weilong immediately had the picture of the drawings in his mind, as for Xiaofeng...... I can't understand it when I stand next to it, that is, I accompany it.

"Captain, but this kind of crossbow will also have a drawback, after all, the True Qi Pill can't kill all opponents."

Hearing Chen Weilong say this, Lin Zichen nodded: "Yes, but even a martial artist can't defeat all opponents, but ...... I think it is possible to place up to three True Qi Pills in the back slot of the crossbow, which can form up to three times the power, so that even if you kill a high-level opponent with one hit, it is not impossible. ”

Chen Weilong smiled when he heard this: "Captain, you are the first person who can combine martial arts and medical skills, and now it seems that you are also the first person who can combine martial arts and combat weapons." ”

"Hehe, everything depends on the effect after it is created, Weilong, give this crossbow a name!"

Chen Weilong nodded, his expression was very serious, after all, this weapon is very likely to accompany his martial arts journey in the future, not a joke.

"Captain, the true qi is bursting, and the crossbow arrows are shot, so it's called the Explosive Dan Crossbow!"

Lin Zichen thought for a while, and the corners of his mouth raised slightly: "Explosive Dan crossbow?" Hehe, let's call it the Explosive Dan Crossbow! ”

In fact, not only Chen Weilong was excited, but Lin Zichen was the same, for him, this not only greatly improved Chen Weilong's attack strength, but also in the future, he could also use the Explosive Dan Crossbow, which could be regarded as killing two birds with one stone.
