Ye Tian couldn't help rolling his eyes. Then he looked back. Now he was only two meters away from the opposite side. He had to walk at least two or three steps!

But now 16 arrows have been shot. What about next time?

Thirty two? Or 64? Or more than 100?

If it is more than 100 roots, even if he does not rely on spiritual power, he may not be able to avoid the past!

But if you use spirit power, who knows what kind of damage these arrows will add.

It's dangerous!

"Hoo... Lao Kang, I'm going forward. You must watch it. This time, it may be more than 100!"

Kang Taiping nodded and began to sweat on his forehead!

Da!

Ye Tian's sole fell down.

When you see the arrow in front of you, Rao takes Ye Tian's character and can't help saying something rude.

"Grass, there are 320 of them."

With that, the spirit power broke out in an instant, and he could not escape by relying on the strength of his body!

Kang Taiping's face turned green when he saw the arrow full of eyes. If it didn't inspire the power of flowers and rootless grass on the other side, he would be shot into a sieve!

At that moment, however, the two people were surprised that the arrow disappeared suddenly, just like the foam in the sunlight.

"What's going on?" Ye Tianyi looks back at Kang Taiping.

"Aside, you don't even think of it with your IQ. Do you think I can know?" Kang Taiping said contemptuously to Ye Tian.

Ye Tian rubs his chin. He really doesn't know what's going on. Everything here is beyond his cognition. He can know a ghost!

No way, ye Tian can only ask the old monster Xueyu, "master, do you know?"

"Oh, nothing. It's just that if you meet someone who uses spirit power, you will automatically give up the attack."

The leaf day suddenly facial expression a black, "the elder how not early say?"

In the blood jade space, the blood jade helplessly spread out her hands, "you didn't ask me, and it's useless for you to ask me, because I just remembered."

Ye Tian wants to be more speechless and speechless. He finds that the spirit of blood jade is not so reliable sometimes!

Now that you know the reason, ye Tian and his wife are very relaxed and go over.

When they walked down the ancient road, the ancient road disappeared.

"Damn, there's no way. How can we go back?" Kang Taiping looks at Ye Tian.

Ye Tian didn't know, so he could only reply, "forget it, go ahead first, and look at it step by step."

Finish saying, continue to walk toward the front, not long, two people looking at the scene in front of, big eyes stare small eyes.

"Well... Why is there such a thing here?" Kang Taiping looks at Ye Tian speechless.

Ye Tian shrugged, "don't ask me, I don't know!"

There is a code door in front of them!

You know, this place can be regarded as a primeval forest place, there is a code door?

This is equivalent to living in ancient times, people are listening in the theater, you just sit by with an MP3, ear earphone, listen to the general!

It's so dramatic!

"Forget it, no matter where it comes from, let's enter the password and hurry to the past!" Kang Taiping waved his hand to Ye Tiandao.

Ye Tianyi didn't look very angry. He pointed to the code door and said, "come on, you can input the code. Do you know what the code is? If there is only one chance to input, what do you do? "

Kang Taiping immediately said, "you come, you come. It's better for you to do this kind of mental work!"

Ye Tian rolled a white eye, and then began to look around, generally like this sudden appearance here with a password, the password should be nearby!

But check for most of the day, ye Tian also did not find any place to record the password!

Even ye Tian on both sides of the tree climbed up to have a look, also did not see any password!

Twenty minutes later, Kang Taiping looked at Ye Tian and asked softly, "Ye Tian, is there any cable?"

Ye Tian shakes his head, and then looks at the password gate. There are four slots in total, that is to say, the password with four numbers. But how can we determine the number?

There is a lock cylinder at the bottom of the password slot, but they didn't get any keys at all. They can only pass according to the password.Then ye Tian continued to look around the corner, did not miss any details, but... Looking for most of the day, still nothing.

All of a sudden, ye Tian's eyes look at the way he came, and then he looks at Kang Tianping.

"Lao Kang, how many steps have you taken along that ancient road?" Ye Tian asked suddenly.

Kang Taiping was stunned, then thought, "1357 steps seems to be!"

Ye Tian nodded, maybe his step is bigger than Kang Taiping's, he only took 1132 steps!

Add the two, that is 2489!

Ye Tian hurried to the password door, Kang Taiping was excited, "do you know the answer?"

"I don't know if it's right, but I have to try it!" Ye Tian finished and entered 2489.

"Password error, there are two opportunities, if not three times, need to continue to unlock a day later!" A slightly mechanical sound suddenly rang out.

Kang Taiping looked like a ghost, "is this code gate so intelligent?"

Ye Tian rolled his eyes. Is it time to pay attention to this?

"Lao Kang, are you sure you are right?" Ye Tianxun asked.

Kang Taiping nodded.

Ye Tian began to rub his chin. So far, apart from the way they walked on the old-fashioned Road, there is no one related to numbers. Is it difficult that the road will stop here?

No, if you don't go back, it's estimated that the Baji boxing club will invite Xia he and others back!

Thinking of this, ye Tian began to sit on the ground and continue to think.

In addition to the steps on the ancient road, where else is there about numbers?

Ten minutes later, ye Tian suddenly stood up, "arrow!"

"Arrow? What arrow? " Kang Taiping looks at Ye Tian and asks.

Ye Tian ignored Kang Taiping, but recalled in his mind that there was one arrow in the first round, two in the second round, and eight in the third round

But the fifth round should be 32, but it increased to 220, which made some mistakes in Ye Tian's reasoning.

"No matter, try it first. Fortunately, after three times, the password gate is not automatically destroyed, but locked. You need to wait until tomorrow to continue to input."

With that, ye Tian put a number in.

"Password error, there is a chance, if not three times, need to continue to unlock a day later!" The mechanical sound sounded again.

This makes Ye Tian frown. What's wrong?

This time, he added the sum of the two men's steps to the number of arrows just now, but it was still wrong!

"Is..." Ye Tian suddenly sounded a possibility.

Just now, because he used spiritual power, those arrows disappeared directly. But what if he didn't use spiritual power? There should be two more arrows in the back!

Because he was only two steps away from the ancient road!

If the last two rounds of arrows follow the previous rule, they are 640 and 1280!

Plus the previous number, it should be the final answer!

Thinking of this, ye Tian entered the answer into the password gate.
