After Lin Feng returned to the Super Scarlet Battle Fortress, he immediately opened the upgrade system of the research institute, and in the excited waiting of Tang Yin, Wei Chiyan and others, he chose to upgrade, and the voice of the system came from his ears, prompting Lin Feng and the others that the research institute has been promoted to a senior research institute +1, and has also studied items such as artillery.

Lin Feng immediately opened the items that could be manufactured, and found that there were indeed more artillery, and in addition, there was one more item, such an item was exactly what Lin Feng needed at the moment, and such an item was the city protective cover. That's right, it's the city protective cover, and it's four, originally, the Scarlet Fortress has no protective cover, and after being promoted to a Super Scarlet Battle Fortress, there is an additional protection function, a protective cover, but it's just a protective cover, just like Brother City, Tang Gate, Black Flame City, etc., it only plays a protective role.

However, what is the Super Scarlet Battle Fortress, this is a Battle Fortress, how can the protective shield not have a counterattack function? The upgraded protective shield of the research institute is a protective shield that can carry out automatic counterattack, which is the green dragon protective cover, the white tiger protective cover, the Vermilion Bird protective cover, and the Xuanwu protective cover.

These four protective shields are not the same as the protective cover of the city, but four statues, placed in the four corners of the city, after the start, there will be four divine beasts, Xuanwu main defense, will be on top of the fortress's original protective cover, plus a protective cover, green dragon, white tiger, Vermilion Bird main attack, will appropriately attack the hostile people, of course, their attack is to consume energy, and this energy is a kind of ore, called Xuanjing ore.

After knowing the effect of this protective cover, Lin Feng and the others showed a smile of surprise on their faces, but where to prepare for this Xuanjing mine, Lin Feng immediately sent a message to the second brother, asking about the Xuanjing mine, it was very unexpected, the second brother actually dug up the Xuanjing mine, and now it is still in the ring, it weighs more than 30 catties, there is no doubt about it, Lin Feng went back directly to get it, and then looked at the manufacturing time of the four divine beasts, and found that there were still 23 hours to complete the manufacturing, Lin Feng and the others could only press the excitement.

After handing over the matter to Tang Yin and the others, Lin Feng went offline directly, tiptoed to Wu Xi Zichen's room, quietly pushed open the door, and found that Zichen was already asleep.

"Zichen, my baby, my brother is here!" Lin Feng shouted in a low voice, followed into Zichen's quilt, reached out and touched it, Ya, this little girl, sleeping naked, didn't lock the door, it seems that she has to be educated.

Soon, Lin Feng's hand touched Zichen's peak, and after a while of kneading, Zichen was already panting, maybe Zichen was too tired, and he didn't wake up, but made a dream-like sound. "Ah Feng, I want it!"

I went, since the beauty wanted, of course I had to meet the beauty's requirements, Lin Feng immediately turned over and got on the horse, supported his little brother, lifted Zichen's slender legs, and straightened his buttocks......

Zichen snorted dreamily, slowly, his eyes opened a slit, and when he saw that he was being pushed by Lin Feng, Zichen's eyes immediately widened, and he was about to exclaim, but Lin Feng immediately blocked her hot lips. After Zichen saw that it was Lin Feng, the long nails of his hands immediately pinched into Lin Feng's back, and Lin Feng, who was in pain, grinned and let go of Zichen's hot lips.

"Begging, I hate it, I actually take advantage of it, while people are sleeping, sneak attack, sneak attack people!" Zichen sneered intermittently.

Zichen's coquettishness aroused Lin Feng's desire even more, and he kept pushing it, and after a long time, he finally sent out his own elixir and jade liquid, lying on Zichen's body, feeling Zichen's full peak.

"Xiao Nizi, say, what are you doing at night, you actually sleep so hard, thanks to me, if you are someone, you will ...... Wet! Lin Feng pinched Zichen's little nose and punished.

"People, they drank a little wine with Sister Nuan Yan at night, so ......" Zichen shyly burrowed into Lin Feng's chest, at this time, Lin Feng had already gotten off Zichen's body and hugged Zichen's neck.

"A little? I can believe that a little bit, I can sleep so dead? Besides, the three of you are known as the iron-blooded triangle, bloodthirsty demons, I don't believe it, you drink a little bit when you drink, by the way, Yan Yan didn't drink it, right? Lin Feng asked.

"Well, Sister Yanyan only drank a glass of red wine, and the doctor said that drinking a little red wine is not a problem, but it will help digestion and be good for the fetus."

"Oh, you guys, if there is such a thing in the future, see how I clean you up!" Lin Feng patted Zichen's buttocks lightly and said, however, Lin Feng didn't expect that Zichen's delicate buttocks were quite elastic!

"Ah Feng, can you sleep with me in your arms tonight?" Zichen raised his head, staring at Lin Feng with sparkling eyes and asked.

"This, I'm going to punish Nuan Yan later, since the beauty has an appointment, of course I have to accompany the beauty!" Lin Feng said with a smile.

"Well, Ah Feng is the best!" Zichen said, lying in the crook of Lin Feng's arm, and gradually fell asleep, Lin Feng was also a little tired, and slowly fell asleep.

At about three o'clock in the morning, Lin Feng was woken up by a gust of fresh wind, and hit a spirit, Lin Feng looked at Zichen who was shrinking in his arms, looking at the smile on the corner of her mouth, Lin Feng kissed it on her forehead, slowly stood up from Zichen's dress, got dressed, and walked out of the room, and at the same time locked the door to avoid any accidents.

Lin Feng, who originally wanted to go to cultivate, walked to the door of Nuan Yan's room, his heart moved, and he immediately put his ear on the door, and there was an even wheezing sound from inside, Lin Feng knew that Nuan Yan was sleeping soundly.

Ya, I actually took the lead in drinking, and I drunk my son's Chen Xiaonizi, and I don't punish you, I feel really uncomfortable.

Lin Feng pushed the door and found that the door was locked, Lin Feng showed a smile on his face, Nuan Yan's sense of self-defense was still quite strong, with a little dark energy, the lock was opened, Lin Feng pushed the door into Nuan Yan's room, locked the door back, Lin Feng quickly took off his clothes and got into Nuan Yan's bed.

Maybe it was because he slept all night, and the strength of the wine with a warm face had already passed, and when he opened his eyes, he saw that it was Lin Feng, who pinched Lin Feng's arms fiercely, squinted his eyes, and gave him a hot kiss.

It's so wet, it's so wet, Lin Feng exclaimed in his heart, there is a lot of water in Nuanyan, and it's very fragrant, I really don't know what Nuan Yan usually eats, and the cloves are actually sweet.

After a hot kiss, Nuan Yan was emotional, Lin Feng was also horny, the little brother was tall, in order to achieve the purpose of punishment, this time, Lin Feng actually turned Nuan Yan onto his body, and he lay down below.

Nuan Yan's cheeks were crimson, and he glanced at Lin Feng whitely, and then helped his little brother into his body......
